AWS Certified SysOps Administrator - Associate Practice Test practice questions, page 19 of 19, with answer review and explanations.

Question 91

An application team is working with a SysOps administrator to define Amazon CloudWatch alarms for an application. The application team does not know the application's expected usage or expected growth. Which solution should the SysOps administrator recommend?

  1. Create CloudWatch alarms that are based on anomaly detection.
  2. Create CloudWatch alarms by using a set of composite alarms.
  3. Create CloudWatch alarms by using static thresholds.
  4. Create CloudWatch alarms that treat missing data as breaching.

Question 92

A company runs a stateless application that is hosted on an Amazon EC2 instance. Users are reporting performance issues. A SysOps administrator reviews the Amazon CloudWatch metrics for the application and notices that the instance's CPU utilization frequently reaches 90% during business hours. What is the MOST operationally efficient solution that will improve the application's responsiveness?

  1. Configure CloudWatch logging on the EC2 instance. Configure a CloudWatch alarm for CPU utilization to alert the SysOps administrator when CPU utilization goes above 90%.
  2. Configure an AWS Client VPN connection to allow the application users to connect directly to the EC2 instance private IP address to reduce latency.
  3. Create an Auto Scaling group, and assign it to an Application Load Balancer. Configure a target tracking scaling policy that is based on the average CPU utilization of the Auto Scaling group.
  4. Create a CloudWatch alarm that activates when the EC2 instance's CPU utilization goes above 80%. Configure the alarm to invoke an AWS Lambda function that vertically scales the instance.

Question 93

An ecommerce company uses an Amazon ElastiCache for Memcached cluster for in-memory caching of popular product queries on the shopping site. When viewing recent Amazon CloudWatch metrics data for the ElastiCache cluster, the SysOps administrator notices a large number of evictions. Which of the following actions will reduce these evictions? (Choose two.)

  1. Add an additional node to the ElastiCache cluster.
  2. Increase the ElastiCache time to live (TTL).
  3. Increase the individual node size inside the ElastiCache cluster.
  4. Put an Elastic Load Balancer in front of the ElastiCache cluster.
  5. Use Amazon Simple Queue Service (Amazon SQS) to decouple the ElastiCache cluster.

Question 94

A SysOps administrator wants to provide access to AWS services by attaching an IAM policy to multiple IAM users. The SysOps administrator also wants to be able to change the policy and create new versions. Which combination of actions will meet these requirements? (Choose two.)

  1. Add the users to an IAM service-linked role. Attach the policy to the role.
  2. Add the users to an IAM user group. Attach the policy to the group.
  3. Create an AWS managed policy.
  4. Create a customer managed policy.
  5. Create an inline policy.

Question 95

A company stores critical data in Amazon S3 buckets. A SysOps administrator must build a solution to record all S3 API activity. Which action will meet this requirement?

  1. Configure S3 bucket metrics to record object access logs.
  2. Create an AWS CloudTrail trail to log data events for all S3 objects.
  3. Enable S3 server access logging for each S3 bucket.
  4. Use AWS IAM Access Analyzer for Amazon S3 to store object access logs.
