Amazon SOA-C02 Exam Questions & Practice Tests

Question No 1

A SysOps administrator is creating two AWS CloudFormation templates. The first template will create a VPC with associated resources, such as subnets, route tables, and an internet gateway. The second template will deploy application resources within the VPC that was created by the first template. The second template should refer to the resources created by the first template. How can this be accomplished with the LEAST amount of administrative effort?

Choose the Choices:

Add an export field to the outputs of the first template and import the values in the second template.

Create a custom resource that queries the stack created by the first template and retrieves the required values.

Create a mapping in the first template that is referenced by the second template.

Input the names of resources in the first template and refer to those names in the second template as a parameter.

Question No 2

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?

Choose the Choices:

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 No 3

A company is running an application on premises and wants to use AWS for data backup. All of the data must be available locally. The backup application can write only to block - based storage that is compatible with the Portable Operating System Interface (POSIX). Which backup solution will meet these requirements?

Choose the Choices:

Configure the backup software to use Amazon S3 as the target for the data backups.

Configure the backup software to use Amazon S3 Glacier as the target for the data backups.

Use AWS Storage Gateway, and configure it to use gateway - cached volumes.

Use AWS Storage Gateway, and configure it to use gateway - stored volumes.

Question No 4

A company asks a SysOps administrator to ensure that AWS CloudTrail files are not tampered with after they are created. Currently, the company uses AWS Identity and Access Management (IAM) to restrict access to specific trails. The company's security team needs the ability to trace the integrity of each file. What is the MOST operationally efficient solution that meets these requirements?

Choose the Choices:

Create an Amazon EventBridge (Amazon CloudWatch Events) rule that invokes an AWS Lambda function when a new file is delivered. Configure the Lambda function to compute an MD5 hash check on the file and store the result in an Amazon DynamoDB table. The security team can use the values that are stored in DynamoDB to verify the integrity of the delivered files.

Create an AWS Lambda function that is invoked each time a new file is delivered to the CloudTrail bucket. Configure the Lambda function to compute an MD5 hash check on the file and store the result as a tag in an Amazon 53 object. The security team can use the information in the tag to verify the integrity of the delivered files.

Enable the CloudTrail file integrity feature on an Amazon S3 bucket. Create an IAM policy that grants the security team access to the file integrity logs that are stored in the S3 bucket.

Enable the CloudTrail file integrity feature on the trail. The security team can use the digest file that is created by CloudTrail to verify the integrity of the delivered files.

Question No 5

A company has an Amazon RDS DB instance. The company wants to implement a caching service while maintaining high availability. Which combination of actions will meet these requirements? (Choose two.)

Choose the Choices:

Add Auto Discovery to the data store.

Create an Amazon ElastiCache for Memcached data store.

Create an Amazon ElastiCache for Redis data store.

Enable Multi - AZ for the data store.

Enable Multi - threading for the data store.
