Question 1

A company has an infernal web application that runs on Amazon EC2 instances behind an Application Load Balancer. The instances run in an Amazon EC2 Auto

Scaling group in a single Availability Zone. A SysOps administrator must make the application highly available.

Which action should the SysOps administrator take to meet this requirement?

Options :

A : Increase the maximum number of instances in the Auto Scaling group to meet the capacity that is required at peak usage.

B : Increase the minimum number of instances in the Auto Scaling group to meet the capacity that is required at peak usage

C : Update the Auto Scaling group to launch new instances in a second Availability Zone in the same AWS Region.

D : Update the Auto Scaling group to launch new instances in an Availability Zone in a second AWS Region.

Answer: C

Question 2

A SysOps administrator wants to monitor the free disk space that is available on a set of Amazon EC2 instances that have Amazon Elastic Block Store (Amazon EBS) volumes attached. The SysOps administrator wants to receive a notification when the used disk space of the EBS volumes exceeds a threshold value, but only when the DiskReadOps metric also exceeds a threshold value. The SysOps administrator has set up an Amazon Simple Notification Service (Amazon SNS) topic.

How can the SysOps administrator receive notification only when both metrics exceed their threshold values?

Options :

A : Install the Amazon CloudWatch agent on the EC2 instances. Create a metric alarm for the disk space and a metric alarm for the DiskReadOps metric. Create a composite alarm that includes the two metric alarms to publish a notification to the SNS topic.

B : Install the Amazon CloudWatch agent on the EC2 instances. Create a metric alarm for the disk space and a metric alarm for the DiskReadOps metric. Configure each alarm to publish a notification to the SNS topic.

C : Create a metric alarm for the EBSByteBalance% metric and a metric alarm for the DiskReadOps metric. Create a composite alarm that includes the two metric alarms to publish a notification to the SNS topic.

D : Configure detailed monitoring for the EC2 instances. Create a metric alarm for the disk space and a metric alarm for the DiskReadOps metric. Create a composite alarm that includes the two metric alarms to publish a notification to the SNS topic

Answer: A

Question 4

A SysOps administrator is troubleshooting a VPC with public and private subnets that leverage custom network ACLs. Instances in the private subnet are unable to access the internet. There is an internet gateway attached to the public subnet. The private subnet has a route to a NAT gateway that is also attached to the public subnet. The Amazon EC2 instances are associated with the default security group for the VPC.

What is causing the issue in this scenario?

Options :

A : There is a network ACL on the private subnet set to deny all outbound traffic.

B : There is no NAT gateway deployed in the private subnet of the VPC.

C : The default security group for the VPC blocks all inbound traffic to the EC2 instances.

D : The default security group for the VPC blocks all outbound traffic from the EC2 instances.

Answer: A
