Correct answer: AWS CloudWatch + AWS SNS

A--Explanation: Amazon SNS can deliver notifications by SMS text message or email to the Amazon Simple Queue Service (SQS) queues or to any HTTP endpoint. The user can configure a web service (HTTP End point) in his data center which receives data and launches an instance in the private cloud. The user should configure the CloudWatch alarm to send a notification to SNS when the “StatusCheckFailed” metric is true for the EC2 instance. The SNS topic can be configured to send a notification to the user’s HTTP endpoint which launches an instance in the private cloud.

Correct answer: Use the 1AM groups and add users as per their role to different groups and apply policy to group

C--Explanation: With AWS 1AM, a group is a collection of 1AM users. A group allows the user to specify permissions for a collection of users, which can make it easier to manage the permissions for those users. A group helps an organization manage access in a better way; instead of applying at the individual level, the organization can apply at the group level which is applicable to all the users who are a part of that group.

Correct answer: Set an AutoScalingRollingUpdate policy in the CloudFormation template to update the stack.

C

Correct answer: The user can use the copy URL functionality of CloudWatch to share the exact details

C--Explanation: Amazon CloudWatch provides the functionality to graph the metric data generated either by the AWS services or the custom metric to make it easier for the user to analyze. The console provides the option to save the URL or bookmark it so that it can be used in the future by typing the same URL. The Copy URL functionality is available under the console when the user selects any metric to view.

Correct answer: Add an action to AWS Trusted Advisor to turn off EC2 instances based on the Low Utilization Amazon EC2 Instances check, terminating instances identified by Trusted Advisor as running for more than 24 hours.

B

Correct answer: He can suspend scaling temporarily

A--Explanation: The user may want to stop the automated scaling processes on the Auto Scaling groups either to perform manual operations or during emergency situations. To perform this, the user can suspend one or more scaling processes at any time. Once it is completed, the user can resume all the suspended processes.-- Reference: htto://docs.aws.amazon.com/autoscaling/latest/userguide/as-suspend-resume-processes.html

Correct answer: Destination: 0.0.0.0/0 and Target: vgw-12345

C--Explanation: The main route table came with the VPC, and it also has a route for the VPN-only subnet. A custom route table is associated with the public subnet. The custom route table has a route over the Internet gateway (the destination is 0.0.0.0/0, and the target is the Internet gateway). If you create a new subnet in this VPC, it’s automatically associated with the main route table, which routes its traffic to the virtual private gateway. If you were to set up the reverse configuration (the main route table with the route to the Internet gateway, and the custom route table with the route to the virtual private gateway), then a new subnet automatically has a route to the Internet gateway.-- Reference: http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC Route Tables.html

Correct answer: Auto Scaling will throw an error since there is a conflict in the schedule of two separate Auto Scaling Processes

A--Explanation: Auto Scaling based on a schedule allows the user to scale the application in response to predictable load changes. The user can also configure the recurring schedule action, which will follow the Linux cron format. As per Auto Scaling, a scheduled action must have a unique time value. If the user attempts to schedule an activity at a time when another existing activity is already scheduled, the call will be rejected with an error message noting the conflict.

Correct answer: Install and configure the unified CloudWatch agent.
