A company’s reporting job that used to run in 15 minutes is now taking an hour to run. An application generates the reports. The application runs on Amazon EC2 instances and extracts data from an Amazon RDS for MySQL database.
A SysOps administrator checks the Amazon CloudWatch dashboard for the RDS instance and notices that the Read IOPS metrics are high, even when the reports are not running. The SysOps administrator needs to improve the performance and the availability of the RDS instance.
Which solution will meet these requirements?

  1. Configure an Amazon ElastiCache cluster in front of the RDS instance. Update the reporting job to query the ElastiCache cluster.
  2. Deploy an RDS read replica. Update the reporting job to query the reader endpoint.
  3. Create an Amazon CloudFront distribution. Set the RDS instance as the origin. Update the reporting job to query the CloudFront distribution.
  4. Increase the size of the RDS instance.

Answer(s): B



A company’s SysOps administrator regularly checks the AWS Personal Health Dashboard in each of the company’s accounts. The accounts are part of an organization in AWS Organizations. The company recently added 10 more accounts to the organization. The SysOps administrator must consolidate the alerts from each account’s Personal Health Dashboard.
Which solution will meet this requirement with the LEAST amount of effort?

  1. Enable organizational view in AWS Health.
  2. Configure the Personal Health Dashboard in each account to forward events to a central AWS CloudTrail log.
  3. Create an AWS Lambda function to query the AWS Health API and to write all events to an Amazon DynamoDB table.
  4. Use the AWS Health API to write events to an Amazon DynamoDB table.

Answer(s): A



A company runs an application on Amazon EC2 instances. The EC2 instances are in an Auto Scaling group and run behind an Application Load Balancer (ALB). The application experiences errors when total requests exceed 100 requests per second. A SysOps administrator must collect information about total requests for a 2-week period to determine when requests exceeded this threshold.
What should the SysOps administrator do to collect this data?

  1. Use the ALB’s RequestCount metric. Configure a time range of 2 weeks and a period of 1 minute. Examine the chart to determine peak traffic times and volumes.
  2. Use Amazon CloudWatch metric math to generate a sum of request counts for all the EC2 instances over a 2-week period. Sort by a 1-minute interval.
  3. Create Amazon CloudWatch custom metrics on the EC2 launch configuration templates to create aggregated request metrics across all the EC2 instances.
  4. Create an Amazon EventBridge (Amazon CloudWatch Events) rule. Configure an EC2 event matching pattern that creates a metric that is based on EC2 requests. Display the data in a graph.

Answer(s): A



A company recently migrated its application to a VPC on AWS. An AWS Site-to-Site VPN connection connects the company’s on-premises network to the VPC. The application retrieves customer data from another system that resides on premises. The application uses an on-premises DNS server to resolve domain records. After the migration, the application is not able to connect to the customer data because of name resolution errors.
Which solution will give the application the ability to resolve the internal domain names?

  1. Launch EC2 instances in the VPC. On the EC2 instances, deploy a custom DNS forwarder that forwards all DNS requests to the on-premises DNS server. Create an Amazon Route 53 private hosted zone that uses the EC2 instances for name servers.
  2. Create an Amazon Route 53 Resolver outbound endpoint. Configure the outbound endpoint to forward DNS queries against the on-premises domain to the on-premises DNS server.
  3. Set up two AWS Direct Connect connections between the AWS environment and the on-premises network. Set up a link aggregation group (LAG) that includes the two connections. Change the VPC resolver address to point to the on-premises DNS server.
  4. Create an Amazon Route 53 public hosted zone for the on-premises domain. Configure the network ACLs to forward DNS requests against the on-premises domain to the Route 53 public hosted zone.

Answer(s): B
