A company is using Amazon CloudFront to serve static content for its web application to its users. The CloudFront distribution uses an existing on-premises website as a custom origin.
The company requires the use of TLS between CloudFront and the origin server. This configuration has worked as expected for several months. However, users are now experiencing HTTP 502 (Bad Gateway) errors when they view webpages that include content from the CloudFront distribution.
What should a SysOps administrator do to resolve this problem?

  1. Examine the expiration date on the certificate on the origin site. Validate that the certificate has not expired. Replace the certificate if necessary.
  2. Examine the hostname on the certificate on the origin site. Validate that the hostname matches one of the hostnames on the CloudFront distribution. Replace the certificate if necessary.
  3. Examine the firewall rules that are associated with the origin server. Validate that port 443 is open for inbound traffic from the internet. Create an inbound rule if necessary.
  4. Examine the network ACL rules that are associated with the CloudFront distribution. Validate that port 443 is open for outbound traffic to the origin server. Create an outbound rule if necessary.

Answer(s): A



An Amazon CloudFront distribution has a single Amazon S3 bucket as its origin. A SysOps administrator must ensure that users can access the S3 bucket only through requests from the CloudFront endpoint.
Which solution will meet these requirements?

  1. Configure S3 Block Public Access on the S3 bucket. Update the S3 bucket policy to allow the GetObject action from only the CloudFront distribution.
  2. Configure Origin Shield in the CloudFront distribution. Update the CloudFront origin to include a custom Origin_Shield header.
  3. Create an origin access identity (OAI). Assign the OAI to the CloudFront distribution. Update the S3 bucket policy to restrict access to the OAI.
  4. Create an origin access identity (OAI). Assign the OAI to the S3 bucket. Update the CloudFront origin to include a custom Origin header with the OAI value.

Answer(s): C



A SysOps administrator is designing a solution for an Amazon RDS for PostgreSQL DB instance. Database credentials must be stored and rotated monthly. The applications that connect to the DB instance send write-intensive traffic with variable client connections that sometimes increase significantly in a short period of time.
Which solution should a SysOps administrator choose to meet these requirements?

  1. Configure AWS Key Management Service (AWS KMS) to automatically rotate the keys for the DB instance. Use RDS Proxy to handle the increases in database connections.
  2. Configure AWS Key Management Service (AWS KMS) to automatically rotate the keys for the DB instance. Use RDS read replicas to handle the increases in database connections.
  3. Configure AWS Secrets Manager to automatically rotate the credentials for the DB instance. Use RDS Proxy to handle the increases in database connections.
  4. Configure AWS Secrets Manager to automatically rotate the credentials for the DB instance. Use RDS read replicas to handle the increases in database connections.

Answer(s): C



A company wants to reduce costs for jobs that can be completed at any time. The jobs currently run by using multiple Amazon EC2 On-Demand Instances and the jobs take slightly less than 2 hours to complete. If a job falls for any reason it must be restarted from the beginning.
Which solution will meet these requirements MOST cost-effectively?

  1. Purchase Reserved Instances for the jobs.
  2. Submit a request for a one-time Spot Instance for the jobs.
  3. Submit a request for Spot Instances with a defined duration for the jobs.
  4. Use a mixture of On-Demand Instances and Spot Instances for the jobs.

Answer(s): C



An environment consists of 100 Amazon EC2 Windows instances. The Amazon CloudWatch agent is deployed and running on all EC2 Instances with a baseline configuration file to capture log files. There is a new requirement to capture the DHCP log files that exist on 50 of the instances.
What is the MOST operationally efficient way to meet this new requirement?

  1. Create an additional CloudWatch agent configuration file to capture the DHCP logs. Use the AWS Systems Manager Run Command to restart the CloudWatch agent on each EC2 instance with the append-config option to apply the additional configuration file.
  2. Log in to each EC2 Instance with administrator rights. Create a PowerShell script to push the needed baseline log files and DHCP log files to CloudWatch.
  3. Run the CloudWatch agent configuration file wizard on each EC2 instance. Verify that the baseline log files are included and add the DHCP log files during the wizard creation process.
  4. Run the CloudWatch agent configuration file wizard on each EC2 instance and select the advanced detail level. This will capture the operating system log files.
