2. When preparing for a compliance assessment of your system built inside of AWS.

What are three best-practices for you to prepare for an audit? (Choose three.)

Gather evidence of your IT operational controls

Request and obtain applicable third-party audited AWS compliance reports and certifications

Request and obtain a compliance and security tour of an AWS data center for a pre-assessment security review

Request and obtain approval from AWS to perform relevant network scans and in-depth penetration tests of your system’s Instances and endpoints

Schedule meetings with AWS’s third-party auditors to provide evidence of AWS compliance that maps to your control objectives

3. You have started a new job and are reviewing your company’s infrastructure on AWS You notice one web application where they have an Elastic Load Balancer (&B) in front of web instances in an Auto Scaling Group When you check the metrics for the ELB in CloudWatch you see four healthy instances in Availability Zone (AZ) A and zero in AZ B There are zero unhealthy instances.

What do you need to fix to balance the instances across AZs?

Set the ELB to only be attached to another AZ

Make sure Auto Scaling is configured to launch in both AZs

Make sure your AMI is available in both AZs

Make sure the maximum size of the Auto Scaling Group is greater than 4

4. You have been asked to leverage Amazon VPC BC2 and SOS to implement an application that submits and receives millions of messages per second to a message queue. You want to ensure your application has sufficient bandwidth between your EC2 instances and SQS

Which option will provide the most scalable solution for communicating between the application and SQS?

Ensure the application instances are properly configured with an Elastic Load Balancer

Ensure the application instances are launched in private subnets with the EBS-optimized option enabled

7. Your application currently leverages AWS Auto Scaling to grow and shrink as load Increases/ decreases and has been performing well. Your marketing team expects a steady ramp up in traffic to follow an upcoming campaign that will result in a 20x growth in traffic over 4 weeks. Your forecast for the approximate number of Amazon EC2 instances necessary to meet the peak demand is 175.

What should you do to avoid potential service disruptions during the ramp up in traffic?

Ensure that you have pre-allocated 175 Elastic IP addresses so that each server will be able to obtain one as it launches

Check the service limits in Trusted Advisor and adjust as necessary so the forecasted count remains within limits.

Change your Auto Scaling configuration to set a desired capacity of 175 prior to the launch of the marketing campaign

Pre-warm your Elastic Load Balancer to match the requests per second anticipated during peak demand prior to the marketing campaign

8. You have an Auto Scaling group associated with an Elastic Load Balancer (ELB). You have noticed that instances launched via the Auto Scaling group are being marked unhealthy due to an ELB health check, but these unhealthy instances are not being terminated.

What do you need to do to ensure trial instances marked unhealthy by the ELB will be terminated and replaced?

Change the thresholds set on the Auto Scaling group health check

Add an Elastic Load Balancing health check to your Auto Scaling group

Increase the value for the Health check interval set on the Elastic Load Balancer

10. An organization has configured a VPC with an Internet Gateway (IGW). pairs of public and private subnets (each with one subnet per Availability Zone), and an Elastic Load Balancer (ELB) configured to use the public subnets. The application s web tier leverages the ELB. Auto Scaling and a mum-AZ RDS database instance. The organization would like to eliminate any potential single points ft failure in this design.

What step should you take to achieve this organization’s objective?

Nothing, there are no single points of failure in this architecture.

Create and attach a second IGW to provide redundant internet connectivity.

Create and configure a second Elastic Load Balancer to provide a redundant load balancer.

Each subnet maps to a single Availability Zone

A CIDR block mask of /25 is the smallest range supported

Instances in a private subnet can communicate with the internet only if they have an Elastic IP.

By default, all subnets can route between each other, whether they are private or public

V Each subnet spans at least 2 Availability zones to provide a high-availability environment

12. You are creating an Auto Scaling group whose Instances need to insert a custom metric into CloudWatch.

Which method would be the best way to authenticate your CloudWatch PUT request?

Create an IAM role with the Put MetricData permission and modify the Auto Scaling launch configuration to launch instances in that role

Create an IAM user with the PutMetricData permission and modify the Auto Scaling launch configuration to inject the userscredentials into the instance User Data

Modify the appropriate Cloud Watch metric policies to allow the Put MetricData permission to instances from the Auto Scaling group

Create an IAM user with the PutMetricData permission and put the credentials in a private repository and have applications on the server pull the credentials as needed

Data is automatically saved as an E8S volume.

Data is automatically saved as an ESS snapshot.

Data is automatically deleted.

Data is unavailable until the instance is restarted.

14. You have a web application leveraging an Elastic Load Balancer (ELB). In front of the web servers deployed using an Auto Scaling Group Your database is running on Relational Database Service (RDS) The application serves out technical articles and responses to them in general there are more views of an article than there are responses to the article. On occasion, an article on the site becomes extremely popular resulting in significant traffic increases that causes the site to go down.

What could you do to help alleviate the pressure on the infrastructure while maintaining availability during these events? (Choose three.)

Leverage CloudFront for the delivery of the articles.

Add RDS read-replicas for the read traffic going to your relational database

Leverage ElastiCache for caching the most frequently used data.

Use SOS to queue up the requests for the technical posts and deliver them out of the queue.

Two public subnets for ELB two public subnets for the web-servers, and two public subnets for RDS

17. An application that you are managing has EC2 instances & Dynamo OB tables deployed to several AWS Regions in order to monitor the performance of the application globally, you would like to see two graphs:

1) Avg CPU Utilization across all EC2 instances

2) Number of Throttled Requests for all DynamoDB tables.

How can you accomplish this?

Tag your resources with the application name, and select the tag name as the dimension in the Cloudwatch Management console to view the respective graphs

Use the Cloud Watch CLI tools to pull the respective metrics from each regional endpoint Aggregate the data offline & store it for graphing in CloudWatch.

Add SNMP traps to each instance and DynamoDB table Leverage a central monitoring server to capture data from each instance and table Put the aggregate data into Cloud Watch for graphing.

Add a CloudWatch agent to each instance and attach one to each DynamoDB table. When configuring the agent set the appropriate application name & view the graphs in CloudWatch.

20. You have two Elastic Compute Cloud (EC2) instances inside a Virtual Private Cloud (VPC) in the same Availability Zone (AZ) but in different subnets. One instance is running a database and the other instance an application that will interface with the database. You want to confirm that they can talk to each other for your application to work properly.

Which two things do we need to confirm in the VPC settings so that these EC2 instances can communicate inside the VPC? (Choose two.)

A network ACL that allows communication between the two subnets.

Both instances are the same instance class and using the same Key-pair.

That the default route is set to a NAT instance or internet Gateway (IGW) for them to communicate.
