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? (Choose two.)

  1. Create an Amazon Elastic File System (Amazon EFS) file system. Mount the file system to the EC2 instances by using user data.
  2. Create a Multi-AZ Network Load Balancer in front of the EC2 instances.
  3. Place the EC2 instances in an Auto Scaling group within a single subnet.
  4. Launch the EC2 instances into a cluster placement group.
  5. Launch the EC2 instances into a partition placement group.

Answer(s): C,D



A company’s customers are reporting increased latency while accessing static web content from Amazon S3. A SysOps administrator observed a very high rate of read operations on a particular S3 bucket.
What will minimize latency by reducing load on the S3 bucket?

  1. Migrate the S3 bucket to a region that is closer to end users’ geographic locations.
  2. Use cross-region replication to replicate all of the data to another region.
  3. Create an Amazon CloudFront distribution with the S3 bucket as the origin.
  4. Use Amazon ElastiCache to cache data being served from Amazon S3.

Answer(s): C



A SysOps administrator needs to develop a solution that provides email notification and inserts a record into a database every time a file is put into an Amazon S3 bucket.
What is the MOST operationally efficient solution that meets these requirements?

  1. Set up an S3 event notification that targets an Amazon Simple Notification Service (Amazon SNS) topic. Create two subscriptions for the SNS topic. Use one subscription to send the email notification. Use the other subscription to invoke an AWS Lambda function that inserts the record into the database.
  2. Set up an Amazon CloudWatch alarm that enters ALARM state whenever an object is created in the S3 bucket. Configure the alarm to invoke an AWS Lambda function that sends the email notification and inserts the record into the database.
  3. Create an AWS Lambda function to send the email notification and insert the record into the database whenever a new object is detected in the S3 bucket. Invoke the function every minute with an Amazon EventBridge (Amazon CloudWatch Events) scheduled rule.
  4. Set up two S3 event notifications. Target a separate AWS Lambda function with each notification. Configure one function to send the email notification. Configure the other function to insert the record into the database.

Answer(s): A
