  Amazon AWS Certified Solutions Architect - Professional Sample Questions (Q85-Q90):

  NEW QUESTION # 85
  A group of Amazon EC2 instances have been configured as high performance computing (HPC) cluster. The instances are running in a placement group, and are able to communicate with each other at network of up to 20 Gbps.
  The cluster needs to communicate with a control EC2 instance outside of the placement group.
  The control instance has the same instance type and AMI as the other instances, and is configured with a public IP address.
  How can the Solutions Architect improve the network speeds between the control instance and the instances in the placement group?

  • A. Ensure that the control instance is using an Elastic Network Adapter.
  • B. Ensure that the instances are communicating using the private IP addresses.
  • C. Move the control instance inside the placement group.
  • D. Terminate the control instance and relaunch in the placement group.

  Answer: D

  Explanation:
  You cannot move an existing instance into a placement group. Instances within a placement group generally have both a public and a private IP address. Communications across a public IP address are limited to 5Gbps or less. Low-latency, high-throughput communications between placement group members can only occur across the private interfaces, using the private IP addresses. These communications can be either 10Gbps or 20Gbps, and are limited by the instance's network configuration.

  NEW QUESTION # 86
  A customer has a 10 GB AWS Direct Connect connection to an AWS region where they have a web application hosted on Amazon Elastic Computer Cloud (EC2). The application has dependencies on an on-premises mainframe database that uses a BASE (Baste Available, Soft state, Eventual consistency) rather than an ACID (Atomicity, Consistency, Isolation, Durability) consistency model. The application is exhibiting undesirable behavior because the database is not able to handle the volume of writes. How can you reduce the load on your on-premises database resources in the most cost-effective way?

  • A. Use an Amazon Elastic Map Reduce (EMR) S3DistCp as a synchronization mechanism between the on- premises database and a Hadoop cluster on AWS.
  • B. Modify the application to write to an Amazon SQS queue and develop a worker process to flush the queue to the on-premises database.
  • C. Provision an RDS read-replica database on AWS to handle the writes and synchronize the two databases using Data Pipeline.
  • D. Modify the application to use DynamoDB to feed an EMR cluster which uses a map function to write to the on-premises database.

  Answer: B
