Question #11 Topic 1

Security groups in VPC operate at the ______.

A data transport layer level
B subnet level
C instance level
D gateway level

Suggested Answer: C
NOTE: You can secure your VPC instances using only security groups. When you launch an instance in a VPC, you can associate one or more security groups that you've created. The security groups act as a firewall for associated Amazon EC2 instances, controlling both inbound and outbound traffic at the instance level. Reference: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Security.html

Question #12 Topic 1

An instance has enabled basic monitoring only for CloudWatch. What is the minimum time period available for basic monitoring?

A 60 seconds
B 360 seconds
C 300 seconds
D 240 seconds

Suggested Answer: C
NOTE: When a user is setting up an alarm on the EC2 instance metric, the time period should be equal to or more than the metric frequency. For basic monitoring, the metric is monitored at every 5 minutes (300 seconds). Reference: http://docs.aws.amazon.com/AmazonCloudWatch/latest/APIReference/API_MetricDatum.html

Question #13 Topic 1

A user has launched an EBS backed EC2 instance in the US-East-1a region. The user stopped the instance and started it back after 20 days. AWS throws up an `˜InsufficientInstanceCapacity' error. What can be the possible reason for this?

A AWS does not have sufficient capacity in that availability zone
B AWS zone mapping is changed for that user account
C There is some issue with the host capacity on which the instance is launched
D The user account has reached the maximum EC2 instance limit

Suggested Answer: A
NOTE: When the user gets an 'InsufficientInstanceCapacity' error while launching or starting an EC2 instance, it means that AWS does not currently have enough available capacity to service the user request. If the user is requesting a large number of instances, there might not be enough server capacity to host them. The user can either try again later, by specifying a smaller number of instances or changing the availability zone if launching a fresh instance.

Question #14 Topic 1

The ______ IAM policy element describes the specific action or actions that will be allowed or de-nied.

Suggested Answer: B
NOTE: The Action element describes the specific action or actions that will be allowed or denied. Statements must include either an Action or NotAction element. Each AWS service has its own set of actions that describe tasks that you can perform with that service. Reference: http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_elements.html
