Question 1343
Exam Question
A solutions architect is designing a VPC with public and private subnets. The VPC and subnets use IPv4 CIDR blocks. There is one public subnet and one private subnet in each of three Availability Zones (AZs) for high availability. An internet gateway is used to provide internet access for the public subnets. The private subnets require access to the internet to allow Amazon EC2 instances to download software updates.
What should the solutions architect do to enable internet access for the private subnets?
A. Create three NAT gateways, one for each public subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic to the NAT gateway in its AZ.
B. Create three NAT instances, one for each private subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic to the NAT instance in its AZ.
C. Create a second internet gateway on one of the private subnets. Update the route table for the private subnets that forward non-VPC traffic to the private internet gateway.
D. Create an egress-only internet gateway on one of the public subnets. Update the route table for the private subnets that forward non-VPC traffic to the egress- only internet gateway.
Correct Answer
A. Create three NAT gateways, one for each public subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic to the NAT gateway in its AZ.
Explanation
To enable internet access for the private subnets in a VPC with public and private subnets, the recommended approach is:
A. Create three NAT gateways, one for each public subnet in each Availability Zone (AZ). Create a private route table for each AZ that forwards non-VPC traffic to the NAT gateway in its AZ.
Here’s why this solution is the most appropriate:
1. NAT Gateways: NAT gateways provide outbound internet access for resources in private subnets. They act as a gateway for the private subnets to communicate with the internet. By creating a NAT gateway in each public subnet, you can establish internet connectivity for the private subnets.
2. Private Route Tables: Each AZ should have its own private route table associated with the corresponding private subnet. In these route tables, you need to add a route that forwards non-VPC (0.0.0.0/0) traffic to the NAT gateway in the same AZ. This ensures that traffic from the private subnets is routed to the NAT gateway for internet access.
3. High Availability: By deploying a NAT gateway in each public subnet across the AZs, you ensure high availability for outbound internet traffic from the private subnets. If one NAT gateway or AZ becomes unavailable, the other NAT gateways in different AZs can continue to provide internet connectivity.
Using NAT gateways and private route tables is the recommended approach for providing internet access to resources in the private subnets while maintaining security and control. It allows EC2 instances in the private subnets to download software updates and access other necessary resources from the internet.
Question 1344
Exam Question
A company has copied 1 PB of data from a colocation facility to an Amazon S3 bucket in the us-east-1 Region using an AWS Direct Connect link. The company now wants to copy the data to another S3 bucket in the us-west-2 Region. The colocation facility does not allow the use of AWS Snowball.
What should a solutions architect recommend to accomplish this?
A. Order a Snowball Edge device to copy the data from one Region to another Region.
B. Transfer contents from the source S3 bucket to a target S3 bucket using the S3 console.
C. Use the aws S3 sync command to copy data from the source bucket to the destination bucket.
D. Add a cross-Region replication configuration to copy objects across S3 buckets in different Regions.
Correct Answer
C. Use the aws S3 sync command to copy data from the source bucket to the destination bucket.
Explanation
If the colocation facility does not allow the use of AWS Snowball, a possible solution to copy the 1 PB of data from one S3 bucket in the us-east-1 Region to another S3 bucket in the us-west-2 Region is:
C. Use the `aws s3 sync` command to copy data from the source bucket to the destination bucket.
The `aws s3 sync` command is a command-line tool provided by the AWS Command Line Interface (CLI) that synchronizes the contents of a local directory or an S3 bucket with a specified S3 bucket. It efficiently copies new and updated files from the source to the destination while minimizing data transfer.
To accomplish the data copy between the S3 buckets in different regions, you can use the `aws s3 sync` command with the appropriate source and destination bucket endpoints:
aws s3 sync s3://source-bucket s3://destination-bucket –region us-west-2
By specifying the source bucket (`s3://source-bucket`) and the destination bucket (`s3://destination-bucket`) with their respective endpoints, you can initiate the synchronization process to copy the data from the source bucket in the us-east-1 Region to the destination bucket in the us-west-2 Region.
Using `aws s3 sync` is a straightforward and efficient way to perform the data copy, and it leverages the network connectivity established via AWS Direct Connect to transfer the data across Regions.
Question 1345
Exam Question
A company has a 10 Gbps AWS Direct Connect connection from its on-premises servers to AWS. The workloads using the connection are critical. The company requires a disaster recovery strategy with maximum resiliency that maintains the current connection bandwidth at a minimum.
What should a solutions architect recommend?
A. Set up a new Direct Connect connection in another AWS Region.
B. Set up a new AWS managed VPN connection in another AWS Region.
C. Set up two new Direct Connect connections: one in the current AWS Region and one in another Region.
D. Set up two new AWS managed VPN connections: one in the current AWS Region and one in another Region.
Correct Answer
C. Set up two new Direct Connect connections: one in the current AWS Region and one in another Region.
Explanation
To meet the requirement of maximum resiliency and maintain the current connection bandwidth, a solutions architect should recommend:
C. Set up two new Direct Connect connections: one in the current AWS Region and one in another Region.
By setting up two new Direct Connect connections, one in the current AWS Region and another in a different Region, you achieve geographical redundancy and maximize resiliency for the critical workloads. This setup ensures that if one Direct Connect connection or Region experiences an outage, the other connection in a different Region can continue to provide connectivity and maintain the required bandwidth.
With two Direct Connect connections, you can also implement a high-availability configuration by using Link Aggregation Groups (LAGs) to combine the two connections into a single logical connection with aggregated bandwidth. This allows you to achieve the desired 10 Gbps bandwidth while ensuring redundancy and failover capability.
Setting up a new Direct Connect connection in another AWS Region provides a disaster recovery strategy with maximum resiliency, as it allows traffic to be routed to the secondary Region in case of a primary Region failure.
It’s worth noting that AWS managed VPN connections (option B) may not provide the same level of bandwidth and resiliency as Direct Connect connections, especially for critical workloads that require a 10 Gbps connection. VPN connections are typically limited in bandwidth and may not offer the same level of performance and reliability as Direct Connect connections.
Question 1346
Exam Question
A company hosts an application used to upload files to an Amazon S3 bucket. Once uploaded, the files are processed to extract metadata, which takes less than 5 seconds. The volume and frequency of the uploads varies from a few files each hour to hundreds of concurrent uploads. The company has asked a solutions architect to design a cost-effective architecture that will meet these requirements.
What should the solutions architect recommend?
A. Configure AWS CloudTrail trails to log S3 API calls. Use AWS AppSync to process the files.
B. Configure an object-created event notification within the S3 bucket to invoke an AWS Lambda function to process the files.
C. Configure Amazon Kinesis Data Streams to process and send data to Amazon S3. Invoke an AWS Lambda function to process the files.
D. Configure an Amazon Simple Notification Service (Amazon SNS) topic to process the files uploaded to Amazon S3. Invoke an AWS Lambda function to process the files.
Correct Answer
B. Configure an object-created event notification within the S3 bucket to invoke an AWS Lambda function to process the files.
Explanation
To design a cost-effective architecture that meets the requirements of uploading files to an S3 bucket and processing them to extract metadata, with varying volume and frequency of uploads, a solutions architect should recommend:
B. Configure an object-created event notification within the S3 bucket to invoke an AWS Lambda function to process the files.
By configuring an object-created event notification, you can trigger an AWS Lambda function whenever a new file is uploaded to the S3 bucket. This allows you to automate the processing of files and extraction of metadata in near real-time.
AWS Lambda is a serverless compute service that can execute code in response to events, such as object uploads in S3. It provides an efficient and cost-effective way to process the files, as you only pay for the actual compute time used during each execution. Lambda functions can scale automatically to handle concurrent uploads, making it suitable for scenarios with varying volume and frequency of uploads, ranging from a few files per hour to hundreds of concurrent uploads.
Additionally, using Lambda with S3 event notifications eliminates the need for continuously polling the bucket for new uploads, reducing unnecessary costs and optimizing resource utilization.
Option A suggests using AWS CloudTrail and AWS AppSync, which may not be the most suitable solution for file uploads and metadata extraction.
Option C suggests using Amazon Kinesis Data Streams, which is typically used for real-time streaming data processing, but may introduce unnecessary complexity and cost for this specific use case.
Option D suggests using Amazon SNS, which is a pub/sub messaging service, but it may not be the most efficient or cost-effective approach for processing file uploads and extracting metadata.
Therefore, option B with S3 event notifications and AWS Lambda is the recommended choice for a cost-effective architecture that meets the requirements.
Question 1347
Exam Question
A company hosts an online shopping application that stores all orders in an Amazon RDS for PostgreSQL Single-AZ DB instance. Management wants to eliminate single points of failure and has asked a solutions architect to recommend an approach to minimize database downtime without requiring any changes to the application code.
Which solution meets these requirements?
A. Convert the existing database instance to a Multi-AZ deployment by modifying the database instance and specifying the Multi-AZ option.
B. Create a new RDS Multi-AZ deployment. Take a snapshot of the current RDS instance and restore the new Multi-AZ deployment with the snapshot.
C. Create a read-only replica of the PostgreSQL database in another Availability Zone. Use Amazon Route 53 weighted record sets to distribute requests across the databases.
D. Place the RDS for PostgreSQL database in an Amazon EC2 Auto Scaling group with a minimum group size of two. Use Amazon Route 53 weighted record sets to distribute requests across instances.
Correct Answer
A. Convert the existing database instance to a Multi-AZ deployment by modifying the database instance and specifying the Multi-AZ option.
Explanation
To minimize database downtime and eliminate single points of failure in an online shopping application hosted on an Amazon RDS for PostgreSQL database, without requiring changes to the application code, a solutions architect should recommend:
A. Convert the existing database instance to a Multi-AZ deployment by modifying the database instance and specifying the Multi-AZ option.
Choosing option A, converting the existing database instance to a Multi-AZ deployment, is the most appropriate solution for achieving high availability and minimizing downtime without requiring application code changes.
With Multi-AZ deployment, Amazon RDS automatically provisions and maintains a synchronized standby replica of the primary database in a different Availability Zone (AZ). Updates made to the primary database are automatically replicated to the standby replica. In the event of a planned or unplanned outage affecting the primary database, Amazon RDS automatically fails over to the standby replica, minimizing downtime and providing continuous availability.
This approach ensures that there is no single point of failure in the database infrastructure, as data is automatically replicated and failover is handled seamlessly by Amazon RDS. There is no need to manually manage replicas or handle the failover process.
Option B suggests creating a new Multi-AZ deployment using a snapshot, which would require migrating the data to a new instance and introducing additional complexity and potential downtime during the migration process.
Option C suggests using read replicas and weighted record sets with Amazon Route 53, which provides read scalability but does not eliminate the single point of failure for the primary database.
Option D suggests using an EC2 Auto Scaling group with multiple instances, which can provide scalability but does not provide automatic failover and high availability for the database.
Therefore, option A is the recommended solution as it ensures high availability, minimizes downtime, and eliminates single points of failure in the database infrastructure without requiring changes to the application code.
Question 1348
Exam Question
A company is experiencing growth as demand for its product has increased. The company’s existing purchasing application is slow when traffic spikes. The application is a monolithic three-tier application that uses synchronous transactions and sometimes sees bottlenecks in the application tier. A solutions architect needs to design a solution that can meet required application response times while accounting for traffic volume spikes.
Which solution will meet these requirements?
A. Vertically scale the application instance using a larger Amazon EC2 instance size.
B. Scale the application’s persistence layer horizontally by introducing Oracle RAC on AWS.
C. Scale the web and application tiers horizontally using Auto Scaling groups and an Application Load Balancer.
D. Decouple the application and data tiers using Amazon Simple Queue Service (Amazon SQS) with asynchronous AWS Lambda calls.
Correct Answer
C. Scale the web and application tiers horizontally using Auto Scaling groups and an Application Load Balancer.
Explanation
To meet the requirements of improving application response times and handling traffic volume spikes in a monolithic three-tier application, a solutions architect should recommend:
C. Scale the web and application tiers horizontally using Auto Scaling groups and an Application Load Balancer.
Option C, scaling the web and application tiers horizontally using Auto Scaling groups and an Application Load Balancer, is the most appropriate solution in this scenario.
By using Auto Scaling groups, the application can dynamically adjust its capacity based on traffic demand. When traffic spikes occur, additional instances of the web and application tiers can be automatically launched to handle the increased load. This horizontal scaling approach improves the application’s ability to handle higher volumes of traffic and reduces the chances of bottlenecks in the application tier.
The Application Load Balancer distributes incoming traffic across the multiple instances of the application, ensuring that the workload is evenly distributed and providing high availability. It also performs health checks on the instances, automatically removing any instances that are unhealthy from the load balancer’s rotation.
Vertical scaling (option A) by using a larger Amazon EC2 instance size may provide some performance improvement, but it may not be sufficient to handle significant traffic spikes and may still result in bottlenecks.
Scaling the application’s persistence layer horizontally with Oracle RAC on AWS (option B) may provide improved performance for database-related operations but may not address the bottlenecks in the application tier.
Decoupling the application and data tiers using Amazon SQS and asynchronous AWS Lambda calls (option D) can improve scalability and responsiveness, but it involves architectural changes and potentially rewriting parts of the application to work with asynchronous processing, which may not be ideal for a monolithic application.
Therefore, option C, scaling the web and application tiers horizontally using Auto Scaling groups and an Application Load Balancer, is the recommended solution to meet the requirements of improving application response times and handling traffic volume spikes in this scenario.
Question 1349
Exam Question
A company has a 143 TB MySQL database that it wants to migrate to AWS. The plan is to use Amazon Aurora MySQL as the platform going forward. The company has a 100 Mbps AWS Direct Connect connection to Amazon VPC.
Which solution meets the company’s needs and takes the LEAST amount of time?
A. Use a gateway endpoint for Amazon S3. Migrate the data to Amazon S3. Import the data into Aurora.
B. Upgrade the Direct Connect link to 500 Mbps. Copy the data to Amazon S3. Import the data into Aurora.
C. Order an AWS Snowmobile and copy the database backup to it. Have AWS import the data into Amazon S3. Import the backup into Aurora.
D. Order four 50-TB AWS Snowball devices and copy the database backup onto them. Have AWS import the data into Amazon S3. Import the data into Aurora.
Correct Answer
C. Order an AWS Snowmobile and copy the database backup to it. Have AWS import the data into Amazon S3. Import the backup into Aurora.
Explanation
To migrate a 143 TB MySQL database to Amazon Aurora MySQL with the least amount of time, the recommended solution is:
C. Order an AWS Snowmobile and copy the database backup to it. Have AWS import the data into Amazon S3. Import the backup into Aurora.
AWS Snowmobile is a secure data transfer service that uses a 45-foot shipping container to transfer large amounts of data. It is designed for transferring exabytes or petabytes of data. In this scenario, the company’s 143 TB MySQL database falls within the Snowmobile’s capabilities.
By ordering an AWS Snowmobile, the company can copy the database backup to the Snowmobile device. AWS will then securely transfer the data to Amazon S3, which provides highly scalable storage for the database backup. Once the data is in Amazon S3, it can be imported into Amazon Aurora MySQL.
This approach is efficient for large-scale data migration because Snowmobile provides a high-speed, secure, and offline transfer option. It eliminates the need to rely solely on the limited bandwidth of the 100 Mbps AWS Direct Connect connection or the time-consuming process of using Snowball devices.
Options A and B involve copying the data to Amazon S3 directly but do not provide a fast and efficient method for transferring the large amount of data within the given time constraints.
Option D, using four 50-TB AWS Snowball devices, is not the most optimal choice as it requires managing multiple devices and performing the data transfer in smaller chunks compared to the Snowmobile’s larger capacity.
Question 1350
Exam Question
A company is deploying a web portal. The company wants to ensure that only the web portion of the application is publicly accessible. To accomplish this, the VPC was designed with two public subnets and two private subnets. The application will run on several Amazon EC2 instances in an Auto Scaling group. SSL termination must be offloaded from the EC2 instances.
What should a solutions architect do to ensure these requirements are met?
A. Configure the Network Load Balancer in the public subnets. Configure the Auto Scaling group in the private subnets and associate it with the Application Load Balancer.
B. Configure the Network Load Balancer in the public subnets. Configure the Auto Scaling group in the public subnets and associate it with the Application Load Balancer.
C. Configure the Application Load Balancer in the public subnets. Configure the Auto Scaling group in the private subnets and associate it with the Application Load Balancer.
D. Configure the Application Load Balancer in the private subnets. Configure the Auto Scaling group in the private subnets and associate it with the Application Load Balancer.
Correct Answer
C. Configure the Application Load Balancer in the public subnets. Configure the Auto Scaling group in the private subnets and associate it with the Application Load Balancer.
Explanation
To ensure that only the web portion of the application is publicly accessible, while offloading SSL termination from the EC2 instances, the recommended solution is:
C. Configure the Application Load Balancer in the public subnets. Configure the Auto Scaling group in the private subnets and associate it with the Application Load Balancer.
In this solution, the Application Load Balancer (ALB) is configured in the public subnets to handle the public traffic and provide SSL termination. The ALB acts as the entry point for the web portal and routes the incoming requests to the EC2 instances in the private subnets.
By placing the EC2 instances in the private subnets and associating them with the ALB, the web application remains isolated and not directly accessible from the internet. The ALB serves as the bridge between the public and private subnets, allowing incoming traffic to reach the EC2 instances while offloading SSL termination.
Option A, configuring the Network Load Balancer (NLB) in the public subnets and associating the Auto Scaling group in the private subnets with the Application Load Balancer (ALB), does not provide the desired outcome of offloading SSL termination from the EC2 instances.
Option B, configuring the Network Load Balancer (NLB) in the public subnets and associating the Auto Scaling group in the public subnets with the ALB, does not meet the requirement of isolating the EC2 instances in the private subnets.
Option D, configuring the Application Load Balancer (ALB) in the private subnets and associating the Auto Scaling group in the private subnets with the ALB, does not allow for public accessibility to the web portion of the application.
Therefore, option C is the correct choice to meet the requirements outlined in the scenario.
