Question 1

A SysOps administrator is optimizing the cost of a workload. The workload is running in multiple AWS Regions and is using AWS Lambda with Amazon EC2 On-Demand Instances for the compute. The overall usage is predictable. The amount of compute that is consumed in each Region varies, depending on the users' locations.

Which approach should the SysOps administrator use to optimize this workload?

A : rchase Compute Savings Plans based on the usage during the past 30 days

B : rchase Convertible Reserved Instances by calculating the usage baseline.

C : rchase EC2 Instance Savings Plane based on the usage during the past 30 days

D : rchase Standard Reserved Instances by calculating the usage baseline.

Answer: A

Question 2

A company has a workload that runs on several Amazon EC2 instances. The company must retain the workload's system logs and application logs for 13 months. The logs must be available for the entire 13 months. The termination of an EC2 instance must not result in the loss of log information. Which solution will meet these requirements?

A : Create an Amazon S3 bucket Apply a bucket policy to expire objects after 13 months. Schedule a shell script to periodically copy the logs to the S3 bucket Ensure that the attached instance profile has permissions to copy logs to the S3 bucket.

B : Create a log group in Amazon CloudWatch Logs. Specify an Expire Events After value of 13 months. Configure the syslog protocol on the EC2 instances to push the logs to the log group. Ensure that the attached instance profile has permissions to push logs to the log group.

C : Create an Amazon S3 bucket. Apply a bucket policy to expire objects after 13 months. Deploy the unified Amazon CloudWatch agent onto the EC2 instances. Configure the agent to store the logs in the S3 bucket. Ensure that the attached instance profile has permissions to store objects in the S3 bucket,

D : Create a log group in Amazon CloudWatch Logs. Specify an Expire Events After value of 13 months Deploy the unified CloudWatch agent onto the EC2 instances. Configure the agent to push the logs to the log group. Ensure that the attached instance profile has permissions to push logs to the log group.

Answer: D

Question 3

The SysOps administrator needs to configure a website for CloudFront when the DNS CNAME record points to an S3 URL instead of CloudFront.

A : Disable S3 Block Public Access on the S3 bucket.

B : Create an S3 access point in the same AWS Region where the S3 bucket is located. Configure the access point policy to allow CloudFront to read from the S3 bucket. Point the CNAME record to the S3 access point name.

C : Modify the value of the DNS CNAME record to be arn:aws:s3:::example-com-website-files instead of the S3 URI.

D : Modify the value of the DNS CNAME record to be dllllllabcdef8.cloudfront.net instead of the S3 URI.

Answer: D

Question 4

A company has an AWS Lambda function in Account A. The Lambda function needs to read the objects in an Amazon S3 bucket in Account B. A SysOps administrator must create corresponding IAM roles in both accounts.

Which solution will meet these requirements?

A : Account A, create a Lambda execution role to assume the role in Account B. In Account B. create a role that the function can assume to gain access to the S3 bucket.

B : Account A, create a Lambda execution role that provides access to the S3 bucket. In Account B, create a role that the function can assume.

C : Account A, create a role that the function can assume. In Account B, create a Lambda execution role that provides access to the S3 bucket.

D : Account A. create a role that the function can assume to gain access to the S3 bucket. In Account B, create a Lambda execution role to assume the role in Account A.

Answer: A

Question 5

The SysOps administrator needs to resolve high disk I/O issues during the bootstrap process of Nitro-based EC2 instances in an Auto Scaling group with gp3 EBS volumes. Options (Select TWO):

A : Increase the EC2 instance size.

B : Increase the EBS volume capacity.

C : Increase the EBS volume IOPS.

D : Increase the EBS volume throughput.

E : Change the instance type to an instance that is not Nitro-based.

Answer: C,D
