A user has configured ELB with Auto Scaling. The user temporarily suspended the Auto Scaling terminate process. What might the Availability Zone Rebalancing process (AZRebalance) conse-quently cause during this period?

• Auto Scaling will keep launching instances in all AZs until the maximum instance number is reached.

• AZ Rebalancing might now allow Auto Scaling to launch or terminate any instances.

• AZ Rebalancing might allow the number instances in an Availability Zone to remain higher than the maximum size

• It is not possible to suspend the terminate process while keeping the launch active.

If you specify only the general endpoint (autoscaling.amazonaws.com), Auto Scaling directs your request to the:

• us-west-2 endpoint

• eu-central-1.

• eu-west-1 endpoint.

• us-east-1 endpoint.

Which of the following statements is true about Auto Scaling?

• You can only delete your Auto Scaling group but not your Auto Scaling setup.

• If the Auto Scaling infrastructure is being deleted, it is not mandatory to delete the launch con-figuration.

• You can only delete your Auto Scaling set up but not your Auto Scaling group.

• If the Auto Scaling infrastructure is being deleted, it is mandatory to delete the launch configura-tion.

A placement group in Amazon EC2 can

• place high memory instances in one logical group.

• logically name and tag different tiers of the system (DB, application, business logic etc).

• isolate any instance-type physically so that groups access local resources.

• reduce network latency and increase network throughput

Which of the following comes before Auto Scaling group creation?

• Creating the Auto Scaling launch config

• Creating the Auto Scaling policy

• Creating the Auto Scaling tags

• Creating the Auto Scaling instance

Can a user depict CloudWatch metrics such as CPU utilization in % and Network I/O in bytes on a single graph?

• No, a user cannot graph two separate metrics on the same graph.

• Yes, a user can graph several metrics over time on a single graph.

• No, a user cannot plot several metrics on a single graph since the units are different.

• Yes, a user can graph multiple metrics on the same graph provided they are of the same instance in the same AZ.

• It is the number of successful records in a PutRecords operation per Amazon Kinesis stream, measured over the specified time period.

• It is the time taken per PutRecords operation to calculate the statistics of the PutRecords opera-tions.

• It is the number of successful PutRecord operations per Amazon Kinesis stream, measured over the specified time period.

Which of the CloudWatch services mentioned below is NOT a part of the AWS free tier?

• 1 million API request/month

• 10 metrics/month

• 15 detailed monitoring metrics

What is a placement group in Amazon EC2?

• It is a logical grouping of EC2 instances within a single Availability Zone
