Free DevOps Engineering on AWS Certification Questions and Answer

Question 1

Which of the following services may be utilized to determine the health of an application in an AWS Blue Green deployment?

Accepted Answer

AWS CloudWatch

Answer

Amazon CloudWatch is a service that monitors AWS resources and applications. CloudWatch gathers and visualizes data, ingests and monitors log files, and creates alarms. It gives system-wide insight into resource use, application performance, and operational health, all of which are critical for detecting application health early in blue/green deployments.

Question 2

You work as a DevOps Engineer for your organization. You've been tasked with developing a continuous integration and continuous delivery model for the application in your firm. You'll need an AWS service to build up the pipelines and describe each stage. Which of the following services is best?

Accepted Answer

AWS Code Pipeline

Answer

AWS Code Pipeline is a continuous delivery service that allows you to model, visualize, and automate the procedures necessary for software release. The various steps of a software release process may be simply modeled and configured. Code Pipeline improves the actions needed to continually build software modifications.

Question 3

You have recently been assigned to manage the Automated resources that your organization has set up in AWS. You want to leverage some of the company's chef recipes for the existing OpsWorks stacks that are already set up in AWS. However, when you get to the recipes area, there is no possibility to add any recipes. What may be the cause of this?

Accepted Answer

The stacks were created without the custom cookbooks option. Just change the stack settings accordingly.

Answer

AWS OpsWorks for Chef Automate allows you establish AWS-managed Chef servers with Chef Automate premium capabilities and manage them with the Chef DK and other Chef tools. A Chef server controls nodes in your environment, records node information, and acts as a central repository for your Chef cookbooks. The cookbooks include recipes that are executed by the Chef Infra client (chef-client) agent on each Chef-managed node. Chef tools such as knife and Test Kitchen may be used to manage nodes and cookbooks on a Chef server under the AWS OpsWorks for Chef Automate service.

Question 4

Your company has an AWS-hosted application that uses DynamoDB. The IT security department has mandated that all source IP addresses that make calls to the DynamoDB tables be logged. Which of the following services may be utilized to meet this requirement?

Accepted Answer

AWS CLoudTrail

Answer

When you create an AWS account, CloudTrail is activated. When something happens in your AWS account, it's logged as a CloudTrail event. In the CloudTrail console, browse to Event history to examine the last 90 days of recorded API activity (management events) in an AWS Region.

Question 5

You're working on a personal project. The application is hosted in an Auto Scaling group. There is only one instance in the ASG, and the EC2 instance may be canceled and restarted at any moment. When a new instance is launched in the ASG, the EC2 DNS name and IP address are updated. You own a hosted zone in redirect 53 and intend to construct a record set to redirect internal traffic to the instance. Which approach of dynamically updating the record set is the most cost-effective?

Accepted Answer

Configure a CloudWatch Event rule to monitor the Auto Scaling events. The CloudWatch Event rule triggers a Lambda function to point the CNAME in the record set to the private DNS of the new EC2 instance.

Answer

In this case, a low-cost technique is necessary. Option A is wrong because Option B is more affordable since the T2.micro EC2 instance is not essential for the combos of CloudWatch Event + Lambda Function.
