NEW QUESTION 16
You work for a startup that has developed a new photo-sharing application for mobile devices. Over recent months your application has increased in popularity; this has resulted in a decrease in the performance of the application due to the increased load. Your application has a two-tier architecture that is composed of an Auto Scaling PHP application tier and a MySQL RDS instance initially deployed with AWS CloudFormation. Your Auto Scaling group has a min value of 4 and a max value of 8. The desired capacity is now at 8 due to the high CPU utilization of the instances. After some analysis, you are confident that the performance issues stem from a constraint in CPU capacity, while memory utilization remains low. You therefore decide to move from the general-purpose M3 instances to the compute-optimized C3 instances. How would you deploy this change while minimizing any interruption to your end users?
- A. Updatethe launch configuration specified in the AWS CloudFormation template with thenew C3 instance type. Also add an UpdatePolicy attribute to your Auto Scalinggroup that specifies an AutoScalingRollingUpdate. Run a stack update with thenew template
- B. Signin to the AWS Management Console, copy the old launch configuration, and createa new launch configuration that specifies the C3 instances. Update the AutoScaling group with the new launch configuration. Auto Scaling will then updatethe instance type of all running instances
- C. Signinto the AWS Management Console and update the existing launch configurationwith the new C3 instance type. Add an UpdatePolicy attribute to your AutoScaling group that specifies an AutoScaling RollingUpdate.
- D. Updatethe launch configuration specified in the AWS CloudFormation template with thenew C3 instance type. Run a stack update with the new template. Auto Scalingwill then update the instances with the new instance type.
Answer: A
Explanation:
Explanation
The AWS Documentation mentions the below
The AWS::AutoScaling::AutoScalingGroup resource supports an UpdatePolicy attribute. This is used to define how an Auto Scaling group resource is updated when an update to the Cloud Formation stack occurs. A common approach to updating an Auto Scaling group is to perform a rolling update, which is done by specifying the AutoScalingRollingUpdate policy. This retains the same Auto Scaling group and replaces old instances with new ones, according to the parameters specified.

If you're trying to configure an AWS Elastic Beanstalk worker tier for easy debugging if there are problems finishing queue jobs, what should you configure?
- A. Configure Enhanced Health Reporting
- B. Configure a Dead Letter Queue
- C. Configure Blue-Green Deployments.
- D. Configure Rolling Deployments.
Answer: B
Explanation:
Elastic Beanstalk worker environments support Amazon Simple Queue Service (SQS) dead letter queues. A dead letter queue is a queue where other (source) queues can send messages that for some reason could not be successfully processed. A primary benefit of using a dead letter queue is the ability to sideline and isolate the unsuccessfully processed messages. You can then analyze any messages sent to the dead letter queue to try to determine why they were not successfully processed.

Which of the following Cache Engines does Opswork have built in support for?
- A. Memcache
- B. Redis
- C. There is no built in support as of yet for any cache engine
- D. Both Redis and Memcache
Answer: A
Explanation:
Explanation
The AWS Documentation mentions
AWS OpsWorks Stacks provides built-in support for Memcached. However, if Redis better suits your requirements, you can customize your stack so that your application servers use OastiCache Redis.
Although it works with Redis clusters, AWS clearly specifies that AWS Opsworks stacks provide built in support for Memcached.
Amazon OastiCache is an AWS service that makes it easy to provide caching support for your application server, using either the Memcached or Redis caching engines. OastiCache can be used to improve the application server performance running on AWS Opsworks stacks.

NEW QUESTION 23
A consulting company was hired to assess security vulnerabilities within a client company's application and propose a plan to remediate all identified issues. The architecture is identified as follows: Amazon S3 storage for content, an Auto Scaling group of Amazon EC2 instances behind an Elastic Load Balancer with attached Amazon EBS storage, and an Amazon RDS MySQL database. There are also several AWS Lambda functions that communicate directly with the RDS database using connection string statements in the code.
The consultants identified the top security threat as follows: the application is not meeting its requirement to have encryption at rest.
What solution will address this issue with the LEAST operational overhead and will provide monitoring for potential future violations?
- A. Configure the application to encrypt each file prior to storing on Amazon S3. Enable OS-based encryption of data on EBS volumes. Encrypt data on write to RDS. Run cron jobs on each instance to check for encrypted data and notify via Amazon SNS. Use S3 Events to call an AWS Lambda function and verify if the file is encrypted.
- B. Enable SSE encryption on the S3 buckets, EBS volumes, and the RDS database. Store RDS credentials in EC2 Parameter Store. Enable a policy on the S3 bucket to deny unencrypted puts.
Set up AWS Config rules to periodically check for non-encrypted S3 objects and EBS volumes, and to ensure that RDS storage is encrypted. - C. Enable SSE encryption on the S3 buckets and RDS database. Enable OS-based encryption of data on EBS volumes. Configure Amazon Inspector agents on EC2 instances to report on insecure encryption ciphers. Set up AWS Config rules to periodically check for non-encrypted S3 objects.
- D. Enable Secure Sockets Layer (SSL) on the load balancer, ensure that AWS Lambda is using SSL to communicate to the RDS database, and enable S3 encryption. Configure the application to force SSL for incoming connections and configure RDS to only grant access if the session is encrypted. Configure Amazon Inspector agents on EC2 instances to report on insecure encryption ciphers.

NEW QUESTION 29
Two teams are working together on different portions of an architecture and are using AWS CloudFormation to manage their resources. One team administers operating system-level updates and patches, while the other team manages application-level dependencies and updates. The Application team must take the most recent AMI when creating new instances and deploying the application.
What is the MOST scalable method for linking these two teams and processes?
- A. The Operating System team uses CloudFormation stack to create an AWS CodePipeline pipeline that builds new AMIs. The team then places the AMI ARNs as parameters in AWS Systems Manager Parameter Store as part of the pipeline output. The Application team specifies a parameter of type ssm in their CloudFormation stack to obtain the most recent AMI ARN from the Parameter Store.
- B. The Operating System team uses CloudFormation stack to create an AWS CodePipeline pipeline that builds new AMIs, then places the latest AMI ARNs in an encrypted Amazon S3 object as part of the pipeline output. The Application team uses a cross-stack reference within their own CloudFormation template to get that S3 object location and obtain the most recent AMI ARNs to use when deploying their application.
- C. The Operating System team maintains a nested stack that includes both the operating system and Application team templates. The Operating System team uses a stack update to deploy updates to the application stack whenever the Application team changes the application code.
- D. The Operating System team uses CloudFormation to create new versions of their AMIs and lists the Amazon Resource names (ARNs) of the AMIs in an encrypted Amazon S3 object as part of the stack output section. The Application team uses a cross-stack reference to load the encrypted S3 object and obtain the most recent AMI ARNs.

Elastic Beanstalk supports the deployment of web applications from Docker containers. With Docker
containers, you can define your own runtime environment. You
can choose your own platform, programming language, and any application dependencies (such as package
managers or tools), that aren't supported by other
platforms. Docker containers are self-contained and include all the configuration information and software
your web application requires to run.
By using Docker with Elastic Beanstalk, you have an infrastructure that automatically handles the details of
capacity provisioning, load balancing, scaling, and
application health monitoring.
