• Question 51:

  A company has migrated a fleet of hundreds of on-premises virtual machines (VMs) to Amazon EC2 instances. The instances run a diverse fleet of Windows Server versions along with several Linux distributions. The company wants a solution that will automate inventory and updates of the operating systems. The company also needs a summary of common vulnerabilities of each instance for regular monthly reviews.

  What should a solutions architect recommend to meet these requirements?

  A. Set up AWS Systems Manager Patch Manager to manage all the EC2 instances. Configure AWS Security Hub to produce monthly reports.
  B. Set up AWS Systems Manager Patch Manager to manage all the EC2 instances. Deploy Amazon Inspector, and configure monthly reports.
  C. Set up AWS Shield Advanced, and configure monthly reports. Deploy AWS Config to automate patch installations on the EC2 instances.
  D. Set up Amazon GuardDuty in the account to monitor all EC2 instances. Deploy AWS Config to automate patch installations on the EC2 instances.
  B. Set up AWS Systems Manager Patch Manager to manage all the EC2 instances. Deploy Amazon Inspector, and configure monthly reports.

• Question 52:

  A company processes large amounts of data by using Amazon EC2 instances in an Auto Scaling group.

  The data processing jobs run for up to 48 hours each week. The data processing jobs can handle interruptions. However, the company wants to minimize the interruptions. The company wants to use the latest generation of Amazon EC2 instances each year.

  Which solution will meet these requirements in the MOST cost-effective way?

  A. Purchase Convertible Reserved Instances (RIs) on an All Upfront basis for a 3-year term for the instance types currently in use.
  B. Purchase Standard Reserved Instances (RIs) on an All Upfront basis for a 1-year term for the instance types in use.
  C. Purchase Spot Instances with a price-capacity-optimized allocation strategy. Override instance types in the Auto Scaling group.
  D. Purchase Spot Instances with a capacity-optimized allocation strategy. Override instance types in the Auto Scaling group.
  D. Purchase Spot Instances with a capacity-optimized allocation strategy. Override instance types in the Auto Scaling group.

  ---

  Explanation

  The correct answer is D because the workload is interruptible, runs for only up to 48 hours each week, and the company wants the most cost-effective solution while also minimizing interruptions. These requirements strongly align with Amazon EC2 Spot Instances. Spot Instances provide significant savings compared with On-Demand pricing and are ideal for batch processing, analytics, and other fault-tolerant workloads that can recover from interruptions.

  To minimize the chance of interruption, the best allocation strategy is capacity-optimized. This strategy places Spot requests into the most available Spot capacity pools, which reduces the likelihood that the running instances will be reclaimed. That is more aligned with the requirement than focusing primarily on the absolute lowest price. By using instance type overrides in the Auto Scaling group, the company can specify multiple acceptable instance types across generations and sizes. This improves access to capacity and helps the company adopt newer generation instances over time without locking into a single family or type.

  Option A is incorrect because Convertible Reserved Instances are not as cost-effective as Spot for an interruptible workload that runs only part of the week, and a 3-year term reduces flexibility.

  Option B is incorrect because Standard Reserved Instances are better for steady-state workloads and do not support the requirement to move to the latest generation each year as flexibly.

  Option C is close, but price-capacity- optimized balances cost and capacity; the question prioritizes minimizing interruptions, so capacity-optimized is the better answer.

  AWS cost optimization guidance recommends Spot Instances with a capacity-focused strategy for fault-tolerant workloads that need low cost and fewer interruptions.

• Question 53:

  A company has an on-premises server that uses an Oracle database to process and store customer information. The company wants to use an AWS database service to achieve higher availability and to improve application performance. The company also wants to offload reporting from its primary database system.

  Which solution will meet these requirements in the MOST operationally efficient way?

  A. Use AWS Database Migration Service (AWS DMS) to create an Amazon RDS DB instance in multiple AWS Regions. Point the reporting functions toward a separate DB instance from the primary DB instance.
  B. Use Amazon RDS in a Single-AZ deployment to create an Oracle database. Create a read replica in the same zone as the primary DB instance. Direct the reporting functions to the read replica.
  C. Use Amazon RDS deployed in a Multi-AZ cluster deployment to create an Oracle database. Direct the reporting functions to use the reader instance in the cluster deployment.
  D. Use Amazon RDS deployed in a Multi-AZ instance deployment to create an Amazon Aurora database. Direct the reporting functions to the reader instances.
  D. Use Amazon RDS deployed in a Multi-AZ instance deployment to create an Amazon Aurora database. Direct the reporting functions to the reader instances.

• Question 54:

  A company uses an Amazon RDS for MySQL instance. To prepare for end-of-year processing, the company added a read replica to accommodate extra read-only queries from the company's reporting tool.

  The read replica CPU usage was 60% and the primary instance CPU usage was 60%. After end-of-year activities are complete, the read replica has a constant 25% CPU usage. The primary instance still has a constant 60% CPU usage. The company wants to rightsize the database and still provide enough performance for future growth.

  Which solution will meet these requirements?

  A. Delete the read replica Do not make changes to the primary instance
  B. Resize the read replica to a smaller instance size Do not make changes to the primary instance
  C. Resize the read replica to a larger instance size Resize the primary instance to a smaller instance size
  D. Delete the read replica Resize the primary instance to a larger instance
  B. Resize the read replica to a smaller instance size Do not make changes to the primary instance

• Question 55:

  A company is deploying a new gaming application on Amazon EC2 instances. The gaming application needs to have access to shared storage.

  The company requires a high-performance solution to give the application the ability to use an existing custom protocol to access shared storage. The solution must ensure low latency and must be operationally efficient.

  Which solution will meet these requirements?

  A. Create an Amazon FSx File Gateway. Create a file share that uses the existing custom protocol. Connect the EC2 instances that host the application to the file share.
  B. Create an Amazon EC2 Windows instance. Install and configure a Windows file share role on the instance. Connect the EC2 instances that host the application to the file share.
  C. Create an Amazon Elastic File System (Amazon EFS) file system. Configure the file system to support Lustre. Connect the EC2 instances that host the application to the file system.
  D. Create an Amazon FSx for Lustre file system. Connect the EC2 instances that host the application to the file system.
  D. Create an Amazon FSx for Lustre file system. Connect the EC2 instances that host the application to the file system.

  ---

  Explanation

  Amazon FSx for Lustreis a high-performance, fully managed file system that is ideal for applications requiring low-latency access to shared storage, especially in use cases like gaming where high throughput and low latency are essential. It integrates easily with EC2 instances, providing fast and scalable shared storage, and supports custom protocols for specific application needs.

  Option A (FSx File Gateway): FSx File Gateway is designed for hybrid cloud storage and is not suited for high-performance gaming workloads.

  Option B (EC2 Windows instance): Setting up a file share on a Windows instance would introduce additional administrative overhead and would not provide the necessary performance.

  Option C (EFS with Lustre): While Lustre is integrated with FSx, EFS does not natively support Lustre.

  D. Place the instances in a cluster placement group. Choose instance types that support enhanced networking.
  D. Place the instances in a cluster placement group. Choose instance types that support enhanced networking.

  ---

  Explanation

  For applications requiring high network throughput and low latency between EC2 instances, AWS recommends using a Cluster Placement Group:

  Cluster Placement Group: Packs instances close together inside an Availability Zone, enabling workloads to achieve the low-latency network performance necessary for tightly-coupled node-to-node communication.

  Enhanced Networking: Selecting instance types that support enhanced networking provides higher bandwidth, higher packet-per-second (PPS) performance, and consistently lower inter-instance latencies.

  By combining a Cluster Placement Group with enhanced networking-enabled instance types, the company can meet the stringent performance requirements of its real-time industrial application.
