AWS Certified SysOps Administrator - Associate (SOA-C02) Questions and Answers

Question 21

A recent organizational audit uncovered an existing Amazon RDS database that is not currently configured for high availability. Given the critical nature of this database, it must be configured for high availability as soon as possible.

How can this requirement be met?

Options:

Switch to an active/passive database pair using the create-db-instance-read-replica with the --availability-zone flag.

Specify high availability when creating a new RDS instance, and live-migrate the data.

Modify the RDS instance using the console to include the Multi-AZ option.

Use the modify-db-instance command with the --na flag.

Question 22

A company has deployed a web application in a VPC that has subnets in three Availability Zones. The company launches three Amazon EC2 instances from an

EC2 Auto Scaling group behind an Application Load Balancer (ALB).

A SysOps administrator notices that two of the EC2 instances are in the same Availability Zone, rather than being distributed evenly across all three Availability

Zones. There are no errors in the Auto Scaling group's activity history.

What is the MOST likely reason for the unexpected placement of EC2 instances?

Options:

One Availability Zone did not have sufficient capacity for the requested EC2 instance type.

The ALB was configured for only two Availability Zones.

The Auto Scaling group was configured for only two Availability Zones.

Amazon EC2 Auto Scaling randomly placed the instances in Availability Zones.

Question 23

A Sysops administrator launches an Amazon EC2 instance from a Windows Amazon Machine Image (AMI). The EC2 instance includes additional Amazon Elastic Block Store (Amazon EBS) volumes. When the instance is launched, none of the additional Amazon Elastic Block Store (Amazon EBS) volumes are initialized and ready for use through a drive letter. The SysOps administrator needs to automate the EBS volume initialization.

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

Options:

Create an Amazon EventBridge rule. Configure an AWS Systems Manager Automation runbook as a target of the EventBridge rule to initialize the disks after an EC2 instance launch event.

Create an AmazolkventBridge rule. Configure an AWS Lambda function as a target of the EventBridge rule to initialize the drives after the AMI is launched.

Create an AWS Config rule to automatically initialize the EBS volumes on Windows EC2 instances.

Add the secondary volume configuration to the DriveLetterMappingConfig.json file. Configure the InitializeDisks.ps1 Windows PowerShell script to run at launch. Create a new AMI from the running EC2 instance.

Question 24

A company manages an application that uses Amazon ElastiCache for Redis with two extra-large nodes spread across two different Availability Zones. The company's IT team discovers that the ElastiCache for Redis cluster has 75% freeable memory. The application must maintain high availability.

What is the MOST cost-effective way to resize the cluster?

Options:

Decrease the number of nodes in the ElastiCache for Redis cluster from 2 to 1.

Deploy a new ElastiCache for Redis cluster that uses large node types. Migrate the data from the original cluster to the new cluster. After the process is complete, shut down the original duster.

Deploy a new ElastiCache for Redis cluster that uses large node types. Take a backup from the original cluster, and restore the backup in the new cluster. After the process is complete, shut down the original cluster.

Perform an online resizing for the ElastiCache for Redis cluster. Change the node types from extra-large nodes to large nodes.
