Question

Which task can only an AWS account root user perform?

A. Changing the AWS Support plan
B. Deleting AWS resources
C. Creating an Amazon EC2 instance key pair
D. Configuring AWS WAF

Answer

A. Changing the AWS Support plan

Explanation 1

The correct answer is A. Changing the AWS Support plan.

The AWS account root user is the superuser of the AWS account. It has full access to all AWS services and resources in the account. This includes the ability to change the AWS Support plan, delete AWS resources, create Amazon EC2 instance key pairs, and configure AWS WAF.

The other options can be performed by IAM users with the appropriate permissions. For example, IAM users can change the AWS Support plan if they have the iam:UpdateAccountPassword permission.

Explanation 2

The correct answer is A. Changing the AWS Support plan.

The AWS account root user is the highest level of access in AWS. It has full control over all AWS resources in the account, including the ability to change the AWS Support plan.

The other options can be performed by users with less privileges, such as IAM users or roles.

Option B, deleting AWS resources, can be performed by IAM users or roles that have been granted the appropriate permissions.
Option C, creating an Amazon EC2 instance key pair, can be performed by IAM users or roles that have been granted the appropriate permissions.
Option D, configuring AWS WAF, can be performed by IAM users or roles that have been granted the appropriate permissions.

Therefore, the only task that can only be performed by an AWS account root user is changing the AWS Support plan.

Here are some other tasks that can only be performed by an AWS account root user:

Creating an AWS account
Changing the account settings
Enabling or disabling Multi-Factor Authentication (MFA)
Resetting the root user password
Deleting the root user account

Explanation 3

The task that can only be performed by an AWS account root user is option A: Changing the AWS Support plan.

Here’s a detailed explanation of why option A is the correct choice:

Option A: Changing the AWS Support plan.

The AWS Support plan determines the level of technical support and assistance provided by AWS.
Changing the AWS Support plan is a task that can only be performed by the AWS account root user.
The root user has full administrative privileges and controls the entire AWS account, including billing and support-related activities.
This task requires access to the account-level settings, which are only accessible to the root user.

Option B: Deleting AWS resources.

Deleting AWS resources can be performed by both the AWS account root user and IAM (Identity and Access Management) users with appropriate permissions.
IAM users can be granted permissions to delete specific resources or have broad deletion rights depending on the assigned policies.
The ability to delete resources is not limited to the root user alone.

Option C: Creating an Amazon EC2 instance key pair.

Creating an Amazon EC2 instance key pair can be performed by both the AWS account root user and IAM users.
IAM users can be assigned the necessary permissions to create key pairs for EC2 instances.
The creation of key pairs is not limited to the root user alone.

Option D: Configuring AWS WAF.

Configuring AWS WAF (Web Application Firewall) can be performed by both the AWS account root user and IAM users.
IAM users can be granted permissions to manage and configure AWS WAF rules and policies.
The configuration of AWS WAF is not limited to the root user alone.

In summary, option A, changing the AWS Support plan, is a task that can only be performed by the AWS account root user. The root user has full administrative privileges and controls the entire AWS account, including support-related activities. Other tasks such as deleting AWS resources, creating EC2 instance key pairs, and configuring AWS WAF can be performed by both the root user and IAM users with appropriate permissions.

Explanation 4

Answer: A. Changing the AWS Support plan

Explanation: The AWS account root user is the email address that you use to sign up for AWS. It has complete access to all AWS services and resources in the account. The root user can perform tasks that other IAM users or roles cannot, such as changing the AWS Support plan, closing the account, or changing the account name or email address. Therefore, option A is the correct answer. Deleting AWS resources, creating an Amazon EC2 instance key pair, and configuring AWS WAF are tasks that can be performed by IAM users or roles with the appropriate permissions. Therefore, options B, C, and D are incorrect.

Explanation 5

The correct answer is A. Changing the AWS Support plan.

The AWS account root user is the email address that you use to sign up for AWS. It has complete and unrestricted access to all the resources and services in your AWS account, including billing, security, and administrative settings. The AWS account root user can perform any task in your AWS account, but some tasks can only be performed by the root user and not by other users or roles. One of these tasks is changing the AWS Support plan.

The AWS Support plan is the level of service and assistance that you receive from AWS. There are four types of AWS Support plans: Basic, Developer, Business, and Enterprise. Each plan offers different benefits and features, such as response times, technical support, case management, and trusted advisor. You can change your AWS Support plan at any time by using the AWS Support Center. However, only the AWS account root user can access the AWS Support Center and change the AWS Support plan. Other users or roles need to have the permission to assume the role of the root user to perform this task.

Option B is incorrect because deleting AWS resources is not a task that can only be performed by the root user. Any user or role that has the necessary permissions can delete AWS resources, such as Amazon EC2 instances, Amazon S3 buckets, or AWS Lambda functions. The permissions are defined by the policies that are attached to the user or role.

Option C is incorrect because creating an Amazon EC2 instance key pair is not a task that can only be performed by the root user. Any user or role that has the necessary permissions can create an Amazon EC2 instance key pair, which is a set of public and private keys that are used to securely connect to an EC2 instance. The permissions are defined by the policies that are attached to the user or role.

Option D is incorrect because configuring AWS WAF is not a task that can only be performed by the root user. Any user or role that has the necessary permissions can configure AWS WAF, which is a web application firewall that protects your web applications from common web exploits. The permissions are defined by the policies that are attached to the user or role.

Therefore, the only task that can only be performed by the AWS account root user among the options is changing the AWS Support plan.

Explanation 6

The correct answer is A. Changing the AWS Support plan. Here is why:

The AWS account root user is the email address that is used to sign up for AWS. It has complete access to all AWS services and resources in the account. The root user can perform some tasks that no other IAM user can, such as changing the AWS Support plan. The AWS Support plan determines the level of technical support and guidance that the account receives from AWS, such as response times, access to experts, and service limits.
Deleting AWS resources, creating an Amazon EC2 instance key pair, and configuring AWS WAF are tasks that can be performed by IAM users with the appropriate permissions. Therefore, options B, C, and D are incorrect.

Explanation 7

The task that can only be performed by an AWS account root user is changing the AWS Support plan. The root user has full administrative access to the AWS account and is the initial user created when setting up the account. This user has unrestricted permissions and can perform actions that other IAM (Identity and Access Management) users or roles may not have permission to do.

Option A, changing the AWS Support plan, requires access to the account’s billing and support settings, which only the root user possesses. This task involves modifying the support plan level, contacting AWS support, and managing the support cases associated with the account.

On the other hand, options B, C, and D can be performed by IAM users or roles with the appropriate permissions. Deleting AWS resources (option B) can be done by users or roles with the necessary permissions to manage and delete resources. Creating an Amazon EC2 instance key pair (option C) and configuring AWS WAF (option D) can also be accomplished by users or roles with the appropriate permissions assigned to them.

It is worth noting that while the root user has extensive privileges, it is generally recommended to create and use IAM users or roles with the least privilege necessary to perform specific tasks. This helps improve security by reducing the risk of accidental or unauthorized actions.

Explanation 8

The correct answer is A. Changing the AWS Support plan. The AWS account root user is the user that is created when you sign up for an AWS account. It has complete administrative privileges and access to all AWS services and resources. One of the tasks that only the root user can perform is changing the AWS Support plan, which determines the level of technical support and guidance that you receive from AWS.

The other options are incorrect because:

B. Deleting AWS resources. This task can be performed by any user that has the necessary permissions to delete the specific resources, such as Amazon EC2 instances, Amazon S3 buckets, or AWS Lambda functions. The root user can delegate permissions to other users by using AWS Identity and Access Management (IAM) policies.
C. Creating an Amazon EC2 instance key pair. This task can be performed by any user that has the necessary permissions to create and manage EC2 key pairs, which are used to securely connect to EC2 instances. The root user can delegate permissions to other users by using IAM policies.
D. Configuring AWS WAF. This task can be performed by any user that has the necessary permissions to configure and manage AWS WAF, which is a web application firewall that protects your web applications from common web exploits. The root user can delegate permissions to other users by using IAM policies.

Explanation 9

The task that can only be performed by an AWS account root user is changing the AWS Support plan (Option A).

The root user has full administrative access to the AWS account. Only the root user can access billing and account-level settings since they have unrestricted permissions. Changing the AWS Support plan involves modifying settings related to the support plan level, contacting AWS Support, and managing support cases for the account.

While the root user can delete AWS resources, create EC2 key pairs, and configure WAF, these tasks can also be performed by IAM users or roles if they have been granted the necessary permissions. IAM users and roles allow restricting access using policies.

To improve security, it is recommended to avoid using the root user for regular tasks and instead create IAM identities with minimum permissions. The root user should mainly be used for administrative functions like changing the AWS Support plan since that requires access to account-level settings.

In summary, of the given options, changing the AWS Support plan is the only task that can solely be performed by the AWS account root user due to its requirement to access billing and support settings at the account level. The other tasks may be performed by the root user or IAM identities with the appropriate permissions.

Explanation 10

The correct answer is A. Changing the AWS Support plan. This is a task that can only be performed by the AWS account root user, according to the AWS documentation. The other options are tasks that can be performed by IAM users with the appropriate permissions. For example, an IAM user with the ec2:CreateKeyPair permission can create an Amazon EC2 instance key pair. An IAM user with the waf:PutWebACL permission can configure AWS WAF. An IAM user with the appropriate permissions for the AWS resources they want to delete can delete those resources. Therefore, these tasks do not require root user credentials.

Explanation 11

The task that can only be performed by an AWS account root user is option A: Changing the AWS Support plan.

Here’s a detailed explanation:

A. Changing the AWS Support plan:

The AWS account root user is the initial user created when you set up your AWS account. It has the highest level of permissions and can perform all administrative tasks in the AWS account.
Changing the AWS Support plan involves selecting and subscribing to a specific AWS Support plan, which typically includes different levels of technical support and access to AWS Support resources.
This task requires access to the AWS account’s billing and support settings, which are typically only accessible to the root user. Other IAM (Identity and Access Management) users and roles may not have the necessary permissions to modify the support plan.

Options B, C, and D can be performed by both the AWS account root user and IAM users with the appropriate permissions:

B. Deleting AWS resources:

IAM users can be granted permissions to delete AWS resources as long as they have the necessary permissions for the specific resource types.

C. Creating an Amazon EC2 instance key pair:

IAM users can also be granted permissions to create EC2 instance key pairs if necessary.

D. Configuring AWS WAF (Web Application Firewall):

IAM users can be given permissions to configure and manage AWS WAF settings, rules, and web ACLs as long as the appropriate permissions are assigned.

In summary, while the AWS account root user has the highest level of permissions and can perform all administrative tasks in the AWS account, other IAM users can be granted specific permissions to perform various tasks within the AWS environment. However, changing the AWS Support plan is typically an action reserved for the root user due to its billing and account management implications.

Explanation 12

A. Changing the AWS Support plan.

The AWS account root user has full access to all resources in the account, including the ability to change the AWS Support plan. This is a task that only the root user can perform. Other tasks such as deleting AWS resources, creating an Amazon EC2 instance key pair, and configuring AWS WAF can be performed by IAM users with the appropriate permissions.

Explanation 13

The correct answer is B. Deleting AWS resources.

Only the root user of an AWS account has the necessary permissions to delete AWS resources, such as EC2 instances, S3 buckets, and RDS instances. This is because the root user has full administrative access to the account and can perform any operation on any resource.

Option A, changing the AWS Support plan, can be done by any user with the appropriate permissions, such as an AWS Support Plan Administrator or a user with the necessary IAM permissions.

Option C, creating an Amazon EC2 instance key pair, can also be done by any user with the appropriate permissions, such as a user with the necessary IAM permissions or an EC2 instance owner.

Option D, configuring AWS WAF, can be done by any user with the appropriate permissions, such as a user with the necessary IAM permissions or an AWS WAF administrator.

Therefore, the only task that only the AWS account root user can perform is deleting AWS resources.

Explanation 14

The correct answer is B – Deleting AWS resources.

The AWS account root user is the account created during AWS signup that has full access to all AWS services and resources. Only the root user has permission to permanently delete AWS resources like S3 buckets, EC2 instances, IAM users etc.

An IAM user with administrative permissions can perform tasks like changing the AWS Support plan (A), creating an EC2 key pair (C) and configuring AWS WAF (D). However, only the root account has permission to permanently delete AWS resources through the AWS Management Console, CLI or API.

Deleting AWS resources is an action that could impact an organization’s resources and billing if not performed carefully. Placing this level of control only with the root user follows security best practices of limiting full access to production systems and resources. IAM users can be assigned granular permissions to manage, but not delete AWS resources as needed without putting the whole AWS environment at risk.

Therefore, the only option that correctly identifies a task that can solely be performed by the AWS account root user is Deleting AWS resources (Option B). The root user maintains full control and ownership over the AWS account.

Explanation 15

The answer to the question is:

C. Creating an Amazon EC2 instance key pair.

Only the AWS account root user has the authority to create an EC2 instance key pair, which is used to securely connect to an Amazon Elastic Compute Cloud (EC2) instance. The root user is the highest-level user in an AWS account, with complete access and control over all AWS resources and services.

Here are some reasons why option C is the correct answer:

Option A, changing the AWS Support plan, can be performed by any user in an AWS account, as it involves managing the support plan for the account, which is a lower-level task compared to creating an EC2 instance key pair.
Option B, deleting AWS resources, can also be performed by any user in an AWS account, as it involves deleting resources that are no longer needed or required.
Option D, configuring AWS WAF, can be performed by any user with the appropriate permissions, as it involves configuring the AWS Web Application Firewall for an AWS resource, which is a lower-level task compared to creating an EC2 instance key pair.

In summary, creating an EC2 instance key pair is a critical task that can only be performed by the AWS account root user, as it grants secure access to the EC2 instances in the account.

Explanation 16

Here is the detailed answer to this question:

The only task that can only be performed by the AWS account root user is deleting AWS resources (Option B).

While an AWS account has only one root user, additional users can be created and those users can be given permissions to perform various tasks. However, deleting AWS resources is a substantial operation that could delete customer data or impact running applications and services. Therefore, AWS only allows the root account user to delete resources to ensure proper authorization for such an impactful action.

The other options can all be performed by non-root IAM users if they have been granted the appropriate permissions:

A – An IAM user can be given permissions to change the AWS Support plan. This is a billing-related operation, not an infrastructure change.

C – IAM users can be granted permissions to create EC2 key pairs via an IAM policy. This does not impact existing resources.

D – IAM users can configure AWS WAF rules if granted the necessary permissions in an IAM policy. WAF is a web application firewall service and does not delete existing infrastructure.

Therefore, the only task restricted solely to the AWS account root user is deleting AWS resources since that is the most impactful operation that could remove customer infrastructure and data. The other options involve operations that do not require root-level permission.

Explanation 17

As an AWS Certified Cloud Practitioner expert, I can confidently answer that the task that can only be performed by an AWS account root user is:

A. Changing the AWS Support plan.

The AWS root user is the highest level of permission in an AWS account, and as such, has complete control over the account’s configurations and resources. The root user is the only user who can perform certain sensitive tasks, such as changing the AWS Support plan.

The other options are not exclusive to the root user:

B. Deleting AWS resources: Any user with the appropriate permissions can delete AWS resources, including the root user.

C. Creating an Amazon EC2 instance key pair: Any user with the appropriate permissions can create an Amazon EC2 instance key pair, including the root user.

D. Configuring AWS WAF: Any user with the appropriate permissions can configure AWS WAF, including the root user.

Therefore, the correct answer is A. Changing the AWS Support plan.

Explanation 18

Only an AWS account root user can change the AWS Support plan.

The AWS Support plan is a contract between AWS and the customer that defines the level of support that the customer will receive.

The AWS Support plan can only be changed by the account root user because this is a critical task that could have a significant impact on the customer’s account.

Explanation 19

The task that can only be performed by an AWS account root user is:

B. Deleting AWS resources

Explanation:
The AWS account root user has full administrative privileges and is the highest level of access in an AWS account. This user is created when you first set up your AWS account. While other IAM (Identity and Access Management) users and roles can be created with varying levels of permissions, only the root user has the authority to perform certain critical actions, such as deleting AWS resources.

Deleting AWS resources can have significant consequences, as it permanently removes the resource and its associated data from your account. Therefore, AWS limits this action to the root user by default to prevent accidental or unauthorized deletion of important resources.

It is important to note that best practices recommend not using the root user for routine tasks or day-to-day operations. Instead, it is recommended to create and use IAM users with appropriate permissions to perform specific actions. By following this practice, you can enforce security and maintain better control over your AWS resources.

Explanation 20

The correct answer is B. Deleting AWS resources.

The AWS account root user is the highest level of access in AWS. It has full permissions to all AWS services and resources in the account. This means that the root user can create, modify, and delete any AWS resource, including billing information.

The other options can be performed by other IAM users or roles, with the appropriate permissions.

Option A, changing the AWS Support plan, can be performed by any user with the appropriate permissions.
Option C, creating an Amazon EC2 instance key pair, can be performed by any user with the appropriate permissions to create EC2 instances.
Option D, configuring AWS WAF, can be performed by any user with the appropriate permissions to configure AWS WAF.

Therefore, the only task that can only be performed by an AWS account root user is deleting AWS resources.

Here are some other tasks that can only be performed by an AWS account root user:

Changing the account settings
Creating and managing IAM users and roles
Enabling and disabling MFA
Deleting billing information

It is important to note that the root user should only be used for the most critical tasks. It is a good practice to create IAM users and roles with specific permissions for day-to-day tasks. This will help to protect your account from unauthorized access.

Explanation 21

The task that can only be performed by an AWS account root user is:
B. Deleting AWS resources.

Explanation:
The AWS account root user is the initial user created when an AWS account is set up. This user has complete administrative access and full control over all AWS resources and services associated with the account. While other IAM (Identity and Access Management) users and roles can be created with specific permissions, the root user retains certain privileges that cannot be delegated to other IAM users or roles.

Option A: Changing the AWS Support plan can be performed by both the root user and IAM users with appropriate permissions. The root user can change the support plan through the AWS Management Console.

Option C: Creating an Amazon EC2 instance key pair can be performed by both the root user and IAM users with the necessary permissions. IAM users can create key pairs using the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs.

Option D: Configuring AWS WAF (Web Application Firewall) can be performed by both the root user and IAM users with the required permissions. IAM users can manage and configure AWS WAF through the AWS Management Console, CLI, or SDKs.

However, option B states that deleting AWS resources can only be performed by the root user. Deleting resources is a critical action that can have a significant impact on an AWS environment, so this privilege is typically restricted to the root user to prevent accidental or unauthorized deletions. Other IAM users can have permissions to manage and delete specific resources, but they cannot delete AWS resources at the account level without root user privileges.
