A company plans to migrate several of its high performance computing (HPC) virtual machines (VMs) to Amazon EC2 instances on AWS. A SysOps administrator must identify a placement group for this deployment. The strategy must minimize network latency and must maximize network throughput between the HPC VMs.
Which strategy should the SysOps administrator choose to meet these requirements?

  1. Deploy the instances in a cluster placement group in one Availability Zone.
  2. Deploy the instances in a partition placement group in two Availability Zones.
  3. Deploy the instances in a partition placement group in one Availability Zone.
  4. Deploy the instances in a spread placement group in two Availability Zones.

Answer(s): A



An errant process is known to use an entire processor and run at 100%. A SysOps administrator wants to automate restarting an Amazon EC2 instance when the problem occurs for more than 2 minutes.
How can this be accomplished?

  1. Create an Amazon CloudWatch alarm for the EC2 instance with basic monitoring. Add an action to restart the instance.
  2. Create an Amazon CloudWatch alarm for the EC2 instance with detailed monitoring. Add an action to restart the instance.
  3. Create an AWS Lambda function to restart the EC2 instance, invoked on a scheduled basis every 2 minutes.
  4. Create an AWS Lambda function to restart the EC2 instance, invoked by EC2 health checks.

Answer(s): B



A company maintains a large set of sensitive data in an Amazon S3 bucket. The company's security team asks a SysOps administrator to help verify that all current objects in the S3 bucket are encrypted.
What is the MOST operationally efficient solution that meets these requirements?

  1. Create a script that runs against the S3 bucket and outputs the status of each object.
  2. Create an S3 Inventory configuration on the S3 bucket. Include the appropriate status fields.
  3. Provide the security team with an IAM user that has read access to the S3 bucket.
  4. Use the AWS CLI to output a list of all objects in the S3 bucket.

Answer(s): B



Users are periodically experiencing slow response times from a relational database. The database runs on a burstable Amazon EC2 instance with a 350 GB General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume. A SysOps administrator monitors the EC2 instance in Amazon CloudWatch and observes that the VolumeReadOps metric drops to less than 10% of its peak value during the periods of slow response.
What should the SysOps administrator do to ensure consistently high performance?

  1. Convert the gp2 volume to a General Purpose SSD (gp3) EBS volume.
  2. Convert the gp2 volume to a Cold HDD (sc1) EBS volume.
  3. Convert the EC2 instance to a memory optimized instance type.
  4. Activate unlimited mode on the EC2 instance.

Answer(s): D
