Question 1371

Exam Question

A solutions architect is designing the storage architecture for a new web application used for storing and viewing engineering drawings. All application components will be deployed on the AWS infrastructure. The application design must support caching to minimize the amount of time that users wait for the engineering drawings to load. The application must be able to store petabytes of data.

Which combination of storage and caching should the solutions architect use?

A. Amazon S3 with Amazon CloudFront
B. Amazon S3 Glacier with Amazon ElastiCache
C. Amazon Elastic Block Store (Amazon EBS) volumes with Amazon CloudFront
D. AWS Storage Gateway with Amazon ElastiCache

Correct Answer

A. Amazon S3 with Amazon CloudFront

Explanation

The recommended combination of storage and caching for the given requirements is:

A. Amazon S3 with Amazon CloudFront.

Amazon S3 (Simple Storage Service) is a highly scalable and durable object storage service that is ideal for storing and retrieving large amounts of data, including engineering drawings. It can handle petabytes of data and provides high durability and availability.

Amazon CloudFront is a content delivery network (CDN) service that caches content at edge locations worldwide, reducing the latency and improving the performance for end users. By using CloudFront with S3, the application can cache the engineering drawings closer to the users, minimizing the time they have to wait for the drawings to load.

Option B, using Amazon S3 Glacier with Amazon ElastiCache, is not suitable for this scenario because Glacier is a long-term archival storage service with high retrieval times, which may not be appropriate for a web application where low-latency access to drawings is required.

Option C, using Amazon Elastic Block Store (Amazon EBS) volumes with Amazon CloudFront, is not the optimal choice as EBS volumes are block-level storage designed for use with EC2 instances, and they do not offer the scalability and durability required for storing petabytes of data.

Option D, using AWS Storage Gateway with Amazon ElastiCache, is not a suitable combination for this scenario. AWS Storage Gateway is used to connect on-premises storage environments with AWS, and it is not necessary in an all-AWS infrastructure. ElastiCache is a caching service, but it is primarily used for in-memory caching of data and is not directly related to storage.

Therefore, option A (Amazon S3 with Amazon CloudFront) is the recommended combination of storage and caching for this web application, providing scalable storage and efficient caching to minimize load times for engineering drawings.

Question 1372

Exam Question

A company currently has 250 TB of backup files stored in Amazon S3 in a vendor’s proprietary format. Using a Linux-based software application provided by the vendor, the company wants to retrieve files from Amazon S3, transform the files to an industry-standard format, and re-upload them to Amazon S3. The company wants to minimize the data transfer charges associated with this conversation.

What should a solution architect do to accomplish this?

A. Install the conversion software as an Amazon S3 batch operation so the data is transformed without leaving Amazon S3.
B. Install the conversion software onto an on-premises virtual machine. Perform the transformation and re-upload the files to Amazon S3 from the virtual machine.
C. Use AWS Snowball Edge devices to expert the data and install the conversion software onto the devices. Perform the data transformation and re-upload the files to Amazon S3 from the Snowball Edge devices.
D. Launch an Amazon EC2 instance in the same Region as Amazon S3 and install the conversion software onto the instance. Perform the transformation and re- upload the files to Amazon S3 from the EC2 instance.

Correct Answer

D. Launch an Amazon EC2 instance in the same Region as Amazon S3 and install the conversion software onto the instance. Perform the transformation and re- upload the files to Amazon S3 from the EC2 instance.

Explanation

To minimize data transfer charges and achieve the desired transformation and re-upload of files, a solution architect should recommend the following approach:

D. Launch an Amazon EC2 instance in the same Region as Amazon S3 and install the conversion software onto the instance. Perform the transformation and re-upload the files to Amazon S3 from the EC2 instance.

By launching an EC2 instance in the same AWS Region as Amazon S3, the data transfer between the EC2 instance and S3 within the same Region is not subject to any data transfer charges. This ensures cost efficiency.

The company can install the Linux-based software application provided by the vendor on the EC2 instance and perform the file transformation. Once the transformation is complete, the transformed files can be re-uploaded to Amazon S3 directly from the EC2 instance. This process minimizes data transfer charges and streamlines the workflow.

Option A, using Amazon S3 batch operations, does not align with the requirement of transforming the files to an industry-standard format. S3 batch operations are designed for processing large numbers of objects in S3 and performing actions on them, but they do not support file format transformation.

Option B, installing the conversion software onto an on-premises virtual machine, would introduce additional data transfer costs for transferring files between on-premises and Amazon S3, which is not desirable in terms of minimizing data transfer charges.

Option C, using AWS Snowball Edge devices, is not necessary in this scenario. Snowball Edge devices are typically used for large-scale data transfers between on-premises and AWS, and while they could be used to export data from S3 and perform transformations, it adds complexity and potential additional costs compared to using an EC2 instance directly.

Therefore, option D (launching an EC2 instance in the same Region as Amazon S3) is the recommended approach to accomplish the file transformation and re-upload while minimizing data transfer charges.

Question 1373

Exam Question

A company has a web application with sporadic usage patterns. There is heavy usage at the beginning of each month, moderate usage at the start of each week, and unpredictable usage during the week. The application consists of a web server and a MySQL database server running inside the data center. The company would like to move the application to the AWS Cloud, and needs to select a cost-effective database platform that will not require database modifications.

Which solution will meet these requirements?

A. Amazon DynamoDB
B. Amazon RDS for MySQL
C. MySQL-compatible Amazon Aurora Serverless
D. MySQL deployed on Amazon EC2 in an Auto Scaling group

Correct Answer

C. MySQL-compatible Amazon Aurora Serverless

Explanation

To meet the requirements of a cost-effective database platform that does not require database modifications, the recommended solution would be:

C. MySQL-compatible Amazon Aurora Serverless

Amazon Aurora Serverless is a fully managed, on-demand, auto-scaling relational database service compatible with MySQL. It is a cost-effective option as it allows you to pay for the actual resources consumed on a per-second basis. It automatically scales capacity based on the workload, handling sudden spikes in usage without any manual intervention.

In this scenario, where the web application experiences sporadic usage patterns with heavy usage at the beginning of each month and moderate usage at the start of each week, Aurora Serverless is well-suited. It can dynamically adjust its capacity to handle these variable workloads, scaling up during peak periods and scaling down during periods of low activity. This flexibility helps in cost optimization as you only pay for the resources used during active periods.

Furthermore, Aurora Serverless is compatible with MySQL, which means you can migrate your existing MySQL database to Aurora without making any modifications to the database schema or code. This makes the migration process seamless and minimizes any disruption to your application.

Options A and B (Amazon DynamoDB and Amazon RDS for MySQL) may not be the best fit for this scenario. DynamoDB is a NoSQL database, and migrating from MySQL to DynamoDB would likely require significant modifications to the database and application code. Amazon RDS for MySQL is a good option for managed MySQL database hosting but does not offer the auto-scaling and cost-optimization benefits of Aurora Serverless.

Option D (MySQL deployed on Amazon EC2 in an Auto Scaling group) would require more management and configuration overhead compared to the fully managed Aurora Serverless. It would also involve manual capacity management and scaling, which might not be ideal for sporadic usage patterns.

Therefore, option C (MySQL-compatible Amazon Aurora Serverless) is the recommended solution for a cost-effective and seamless migration of the web application’s database to the AWS Cloud.

Question 1374

Exam Question

A company is migrating a NoSQL database cluster to Amazon EC2. The database automatically replicates data to maintain at least three copies of the data. I/O throughput of the servers is the highest priority.

Which instance type should a solutions architect recommend for the migration?

A. Storage optimized instances with instance store
B. Burstable general purpose instances with an Amazon Elastic Block Store (Amazon EBS) volume
C. Memory optimized instances with Amazon Elastic Block Store (Amazon EBS) optimization enabled
D. Compute optimized instances with Amazon Elastic Block Store (Amazon EBS) optimization enabled

Correct Answer

A. Storage optimized instances with instance store

Explanation

To prioritize I/O throughput for the migration of a NoSQL database cluster to Amazon EC2, the recommended instance type would be:

A. Storage optimized instances with instance store

Storage optimized instances are designed to deliver high disk throughput and low latency, making them ideal for workloads that require intensive I/O operations, such as a NoSQL database cluster. These instances come with local instance store volumes, which provide high-performance, low-latency storage directly attached to the host server.

By utilizing instance store volumes, you can achieve higher I/O throughput compared to Amazon Elastic Block Store (Amazon EBS) volumes, as the data is accessed locally without going through a network interface. This is particularly advantageous for workloads that prioritize I/O performance.

It’s important to note that instance store volumes are ephemeral and do not persist data after instance termination. However, since the database in question automatically replicates data to maintain at least three copies, the reliance on instance store volumes aligns well with this requirement. The database can leverage its replication mechanisms to ensure data durability.

Option B, burstable general purpose instances with an Amazon EBS volume, might not offer the same level of I/O throughput as storage optimized instances with instance store. Burstable instances are more suited for workloads with burstable performance requirements but may not provide consistent high I/O throughput.

Options C and D (memory optimized instances and compute optimized instances) focus on other aspects of performance, such as memory capacity or computational power, rather than I/O throughput. While they can still provide decent I/O performance, storage optimized instances with instance store are specifically designed for high disk throughput, making them the recommended choice in this scenario.

Question 1375

Exam Question

A company has a large Microsoft SharePoint deployment running on-premises that requires Microsoft Windows shared file storage. The company wants to migrate this workload to the AWS Cloud and is considering various storage options. The storage solution must be highly available and integrated with Active Directory for access control.

Which solution will satisfy these requirements?

A. Configure Amazon EFS storage and set the Active Directory domain for authentication.
B. Create an SMB file share on an AWS Storage Gateway file gateway in two Availability Zones.
C. Create an Amazon S3 bucket and configure Microsoft Windows Server to mount it as a volume.
D. Create an Amazon FSx for Windows File Server file system on AWS and set the Active Directory domain for authentication.

Correct Answer

D. Create an Amazon FSx for Windows File Server file system on AWS and set the Active Directory domain for authentication.

Explanation

To satisfy the requirements of a highly available storage solution integrated with Active Directory for accessing Microsoft Windows shared files in the AWS Cloud, the recommended solution would be:

D. Create an Amazon FSx for Windows File Server file system on AWS and set the Active Directory domain for authentication.

Amazon FSx for Windows File Server is a fully managed native Windows file system that provides compatibility with the Microsoft Windows file storage and Active Directory environment. It offers high availability, durability, and performance while seamlessly integrating with existing Active Directory domains. FSx for Windows File Server supports the SMB protocol, making it an ideal choice for migrating Microsoft SharePoint deployments that require Windows shared file storage.

By creating an FSx for Windows File Server file system, you can easily mount the file system to your SharePoint environment in the AWS Cloud. The file system is highly available within an AWS Availability Zone, and you can enable automatic backups for data protection and disaster recovery.

FSx for Windows File Server natively integrates with your existing Active Directory infrastructure, allowing you to maintain consistent access controls and authentication mechanisms. This ensures that your SharePoint deployment can seamlessly interact with the file system while preserving the security and access controls provided by Active Directory.

Option A (Amazon EFS) does provide a scalable and managed file storage solution, but it does not integrate directly with Active Directory for authentication, which is a specific requirement mentioned in the scenario.

Option B (AWS Storage Gateway file gateway) provides an SMB file share, but it may not offer the same level of integration with Active Directory as FSx for Windows File Server. It also requires setting up and managing a Storage Gateway in addition to the file share.

Option C (mounting an S3 bucket as a volume) is not directly compatible with the Microsoft Windows file system and may require additional configuration and third-party tools to enable Windows shared file storage.

Therefore, the most suitable option that satisfies the requirements is to create an Amazon FSx for Windows File Server file system and set the Active Directory domain for authentication.
