A web application runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Auto Scaling group across multiple Availability Zones. A SysOpe administrator notices that some of these EC2 instances show up as heathy in the Auto Scaling g-out but show up as unhealthy in the ALB target group. What is a possible reason for this issue?

A. Security groups ate rot allowing traffic between the ALB and the failing EC2 instances

B. The Auto Seating group health check is configured for EC2 status checks

C. The EC2 instances are failing to launch and failing EC2 status checks.

D. The target group health check is configured with an incorrect port or path

A company's SysOps administrator deploys a public Network Load Balancer (NLB) in front of the company's web application. The web application does not use any Elastic IP addresses. Users must access the web application by using the company's domain name. The SysOps administrator needs to configure Amazon Route 53 to route traffic to the NLB. Which solution will meet these requirements MOST cost-effectively?

A. Create a Route 53 AAAA record for the NLB.

B. Create a Route 53 alias record for the NLB.

C. Create a Route 53 CAA record for the NLB.

A company has developed a service that is deployed on a fleet of Linux-based Amazon EC2 instances that are in an Auto Scaling group. The service occasionally fails unexpectedly because of an error in the application code. The company's engineering team determines that resolving the underlying cause of the service failure could take several weeks. A SysOps administrator needs to create a solution to automate recovery if the service crashes on any of the EC2 instances. Which solutions will meet this requirement? (Select TWO.)

A. Install the Amazon CloudWatch agent on the EC2 instances. Configure the CloudWatch agent to monitor the service. Set the CloudWatch action to restart if the service health check fails.

B. Tag the EC2 instances. Create an AWS Lambda function that uses AWS Systems Manager Session Manager to log in to the tagged EC2 instances and restart the service. Schedule the Lambda function to run every 5 minutes.

C. Tag the EC2 instances. Use AWS Systems Manager State Manager to create an association that uses the AWS-RunSheIIScript document. Configure the association command with a script that checks if the service is running and that starts the service if the service is not running. For targets, specify the EC2 instance tag. Schedule the association to run every 5 minutes.

D. Update the EC2 user data that is specified in the Auto Scaling group's launch template to include a script that runs on a cron schedule every 5 minutes.

E. Update the EC2 user data that is specified in the Auto Scaling group's launch template to ensure that the service runs during startup. Redeploy all the EC2 instances in the Auto Scaling group with the updated launch template.

A company is using an Amazon CloudWatch alarm lo monitor the FreeLocalStorage metric for an Amazon Aurora PostgreSQL production database The alarm goes into ALARM state and indicates that the database is running low on temporary storage. A SysOps administrator discovers that a weekly report is using most of the temporary storage that is currently allocated. What should the SysOps administrator do to solve this problem?

A. Turn on Aurora PostgreSQL query plan management.

B. Modify the configuration of the DB cluster to turn on storage auto scaling.

C. Add an Aurora read replica to the DB cluster. Modify the report lo use the new read replica.

D. Modify the DB instance class for each DB instance In the DB cluster to increase the instance size.

A SysOps administrator must ensure that all of a company's current and future Amazon S3 buckets have logging enabled If an S3 bucket does not have logging enabled an automated process must enable logging for the S3 bucket. Which solution will meet these requirements?

A. Use AWS Trusted Advisor 10 perform a check for S3 buckets that do not have logging enabled Configure the check to enable logging for S3 buckets that do not have logging enabled.

B. Configure an S3 bucket policy that requires all current and future S3 buckets to have logging enabled

C. Use the s3-bucket-logging-enabled AWS Config managed rule. Add a remediation action that uses an AWS Lambda function to enable logging.

D. Use the s3-bucket-logging-enabled AWS Config managed rule. Add a remediation action that uses the AWS-ConfigureS3BucketLoggmg AWS Systems Manager Automation runbook to enable logging.

A SysOps administrator needs to implement a backup strategy for Amazon EC2 resources and Amazon RDS resources. The backup strategy must meet the following retention requirements:
• Daily backups: must be kept for 6 days
• Weekly backups: must be kept for 4 weeks:
• Monthly backups: must be kept for 11 months
• Yearly backups: must be kept for 7 years
Which backup strategy will meet these requirements with the LEAST administrative effort?

A. Use Amazon Data Lifecycle Manager to create an Amazon Elastic Block Store (Amazon EBS) snapshot policy. Create tags on each resource that needs to be backed up. Create multiple schedules according to the requirements within the policy. Set the appropriate frequency and retention period.

B. Use AWS Backup to create a new backup plan for each retention requirement with a backup frequency of daily, weekly, monthly, or yearly. Set the retention period to match the requirement. Create tags on each resource that needs to be backed up. Set up resource assignment by using the tags.

C. Create an AWS Lambda function. Program the Lambda function to use native tooling to take backups of file systems in Amazon EC2 and to make copies of databases in Amazon RDS. Create an Amazon EventBridge rule to invoke the Lambda function.

D. Use Amazon Data Lifecycle Manager to create an Amazon Elastic Block Store (Amazon EBS) snapshot policy. Create tags on each resource that needs to be backed up. Set up resource assignment by using the tags. Create multiple schedules according to the requirements within the policy. Set the appropriate frequency and retention period. In Amazon RDS, activate automated backups on the required DB instances.

A Sysops administrator configured AWS Backup to capture snapshots from a single Amazon EC2 instance that has one Amazon Elastic Block Store (Amazon EBS) volume attached. On the first snapshot, the EBS volume has 10 GiB of data. On the second snapshot, the EBS volume still contains 10 GiB of data, but 4 GiB have changed.

A. 12 GiB

B. 16 GiB

C. 26 GiB

D. 32 GiB

A SysOps administrator must configure a resilient tier of Amazon EC2 instances for a high performance computing (HPC) application. The HPC application requires minimum latency between nodes Which actions should the SysOps administrator take to meet these requirements? (Select TWO.)

A. Ensure that all the EC2 instances have the correct tags for Systems Manager access.

B. Configure AWS Identity and Access Management Access Analyzer to determine and automatically remediate the issue.

C. Ensure that all the EC2 instances have an instance profile with Systems Manager access.

D. Configure Systems Manager to use an interface VPC endpoint.

A user working in the Amazon EC2 console increased the size of an Amazon Elastic Block Store (Amazon EBS) volume attached to an Amazon EC2 Windows instance. The change is not reflected in the file system. What should a SysOps administrator do to resolve this issue?
