NEW QUESTION # 431
After a daily scrum with your development teams, you've agreed that using Blue/Green style deployments
would benefit the team. Which technique should you use to deliver this new requirement?

  • A. Create a new Autoscaling group with the new launch configuration and desired capacity same as that of
    the initial Autoscaling group and
    associate it with the same load balancer. Once the new AutoScaling group's instances got registered with
    ELB, modify the desired capacity of the initial AutoScal ing group to zero and gradually delete the old
    Auto scaling group. *>/
  • B. Using an AWS OpsWorks stack, re-deploy your application behind an Elastic Load Balancing load
    balancer and take advantage of OpsWorks stack versioning, during deployment create a new version of
    your application, tell OpsWorks to launch the new version behind your load balancer, and when the new
    version is launched, terminate the old OpsWorks stack.
  • C. Re-deploy your application on AWS Elastic Beanstalk, and take advantage of Elastic Beanstalk
    deployment types.
    B- Using an AWS CloudFormation template, re-deploy your application behind a load balancer, launch
    a new AWS CloudFormation stack during each deployment, update your load balancer to send half your
    traffic to the new stack while you test, after verification update the load balancer to send 100% of traffic
    to the new stack, and then terminate the old stack.

Answer: B

Explanation:
Explanation
This is given as a practice in the Green Deployment Guides

A blue group carries the production load while a green group is staged and deployed with the new code. When
if s time to deploy, you simply attach the green group to
the existing load balancer to introduce traffic to the new environment. For HTTP/HTTP'S listeners, the load
balancer favors the green Auto Scaling group because it uses a least outstanding requests routing algorithm
As you scale up the green Auto Scaling group, you can take blue Auto Scaling group instances out of service
by either terminating them or putting them in Standby state.

NEW QUESTION # 432
Your company is supporting a number of applications that need to be moved to AWS. Initially they thought of moving these applications to the Elastic beanstalk service. When going to the Elastic beanstalk service, you can see that the underlying platform service is not an option in the Elastic beanstalk service. Which of the following options can be used to port your application onto Elastic beanstalk

  • A. Createa docker container for the custom application and then deploy it to Elasticbeanstalk.
  • B. Usethe Opswork service to create a stack. In the stack, create a separate customlayer. Deploy the appl ication to this layer and then attach the layer toElastic beanstalk
  • C. Usecustom chef recipe's to deploy your application in Elastic beanstalk.
  • D. Usecustom Cloudformation templates to deploy the application into Elasticbeanstalk

Answer: A

Explanation:
Explanation
The AWS documentation mentions the following
Clastic 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.

NEW QUESTION # 433
You are designing a system which needs, at minumum, 8 m4.large instances operating to service traffic. When designing a system for high availability in the us-east-1 region, which has 6 Availability Zones, you company needs to be able to handle death of a full availability zone. How should you distribute the servers, to save as much cost as possible, assuming all of the EC2 nodes are properly linked to an ELB?
Your VPC account can utilize us-east-1's AZ's a through f, inclusive.

  • A. 8 servers in each of AZ's a and b.
  • B. 2 servers in each of AZ's a through e, inclusive.
  • C. 3 servers in each of AZ's a through d, inclusive.
  • D. 4 servers in each of AZ's a through c, inclusive.

Answer: B

Explanation:
You need to design for N+1 redundancy on Availability Zones. ZONE_COUNT = (REQUIRED_INSTANCES / INSTANCE_COUNT_PER_ZONE) + 1. To minimize cost, spread the instances across as many possible zones as you can. By using a though e, you are allocating
5 zones. Using 2 instances, you have 10 total instances. If a single zone fails, you have 4 zones left, with 2 instances each, for a total of 8 instances. By spreading out as much as possible, you have increased cost by only 25% and significantly de-risked an availability zone failure.

NEW QUESTION # 434
Which of the following Cloudformation helper scripts can help install packages on EC2 resources

  • A. cfn-hup
  • B. cfn-init
  • C. cfn-get-metadata
  • D. cfn-signal

Answer: B

Explanation:
Explanation
The AWS Documentation mentions
Currently, AWS CloudFormation provides the following helpers:
cf n-init: Used to retrieve and interpret the resource metadata, installing packages, creating files and starting services.
cf n-signal: A simple wrapper to signal an AWS CloudFormation CreationPolicy or WaitCondition, enabling you to synchronize other resources in the stack with the application being ready.
cf n-get-metadata: A wrapper script making it easy to retrieve either all metadata defined for a resource or path to a specific key or subtree of the resource metadata.
cf
n-hup: A daemon to check for updates to metadata and execute custom hooks when the changes are detected.

NEW QUESTION # 435
How can you resolve a dependency Error when using Cloudformation?

  • A. Usethe mappings attribute
  • B. UsetheDependsOn attribute
  • C. Use the Error attribute
  • D. Usethe parameter attribute

Answer: B

Explanation:
Explanation
The AWS troubleshooting guide for Cloudformation states the following
To resolve a dependency error, add a DependsOn attribute to resources that depend on other resources in your
template. In some cases, you must explicitly declare dependencies so that AWS Cloud Formation can create or
delete resources in the correct order. For example, if you create an Elastic IP and a VPC with an Internet
gateway in the same stack, the Elastic IP must depend on the Internet gateway attachment.
