Q221. A web-startup runs its very successful social news application on Amazon EC2 with an Elastic Load Balancer, an Auto-Scaling group of Java/Tomcat application-servers, and DynamoDB as data store. The main web-application best runs on m2 x large instances since it is highly memory- bound Each new deployment requires semi-automated creation and testing of a new AM for the application servers which takes quite a while ana is therefore only done once per week.
Recently, a new chat feature has been implemented in nodejs and wails to be integrated in the architecture. First tests show that the new component is CPU bound Because the company has some experience with using Chef, they decided to streamline the deployment process and use AWS Ops Works as an application life cycle tool to simplify management of the application and reduce the deployment cycles.
What configuration in AWS Ops Works is necessary to integrate the new chat module in the most cost-efficient and filexible way?
A. Create one AWS OpsWorks stack, create one AWS Ops Works layer, create one custom recipe
B. Create one AWS OpsWorks stack create two AWS Ops Works layers create one custom recipe
C. Create two AWS OpsWorks stacks create two AWS Ops Works layers create one custom recipe
D. Create two AWS OpsWorks stacks create two AWS Ops Works layers create two custom recipe
Answer: C
Q222. Amazon EBS provides the ability to create backups of any Amazon EC2 volume into what is known as
A. snapshots
B. images
C. instance backups
D. mirrors
Answer: A
Explanation:
Amazon allows you to make backups of the data stored in your EBS volumes through snapshots that can later be used to create a new EBS volume.
Reference: http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/Storage.htmI
Q223. A user wants to increase the durability and availability of the EBS volume. Which of the below mentioned actions should he perform?
A. Take regular snapshots.
B. Create an AMI.
C. Create EBS with higher capacity.
D. Access EBS regularly.
Answer: A
Explanation:
In Amazon Web Services, Amazon EBS volumes that operate with 20 GB or less of modified data since their most recent snapshot can expect an annual failure rate (AFR) between 0.1% and 0.5%. For this reason, to maximize both durability and availability of their Amazon EBS data, the user should frequently create snapshots of the Amazon EBS volumes.

Q224. A user is planning a highly available application deployment with EC2. Which of the below mentioned options will not help to achieve HA?
A. Elastic IP address
B. PIOPS
C. AMI
D. Availability Zones
Answer: B
Explanation:
In Amazon Web Service, the user can achieve HA by deploying instances in multiple zones. The elastic IP helps the user achieve HA when one of the instances is down but still keeps the same URL. The AM helps launching the new instance. The PIOPS is for the performance of EBS and does not help for HA. Reference: http://media.amazonwebservices.com/AWS_Web_Hosting_Best_Practices.pdf
Q225. Do you need to shutdown your EC2 instance when you create a snapshot of EBS volumes that serve as root devices?
A. No, you only need to shutdown an instance before deleting it.
B. Yes
C. No, the snapshot would turn off your instance automatically.
D. No
Answer: B
Explanation:
Yes, to create a snapshot for Amazon EBS volumes that serve as root devices, you should stop the instance before taking the snapshot.

Q226. George has launched three EC2 instances inside the US-East-1a zone with his AWS account. Ray has launched two EC2 instances in the US-East-Ia zone with his AWS account. Which of the below mentioned statements will help George and Ray understand the availability zone (AZ) concept better?
A. All the instances of George and Ray can communicate over a private IP with a minimal cost
B. The US-East-1a region of George and Ray can be different availability zones
C. All the instances of George and Ray can communicate over a private IP without any cost
D. The instances of George and Ray will be running in the same data centre
Answer: B
Explanation:
Each AWS region has multiple, isolated locations known as Availability Zones. To ensure that the AWS resources are distributed across the Availability Zones for a region, AWS independently maps the Availability Zones to identifiers for each account. In this case the Availability Zone US-East-Ia where George’s EC2 instances are running might not be the same location as the US-East-Ia zone of Ray’s EC2 instances. There is no way for the user to coordinate the Availability Zones between accounts.

Q227. Can I initiate a "forced failover" for my MySQL Multi-AZ DB Instance deployment?
A. Only in certain regions
B. Only in VPC
C. Yes
D. No
Answer: A
Q228. You have been asked to set up a database in AWS that will require frequent and granular updates. You know that you will require a reasonable amount of storage space but are not sure of the best option. What is the recommended storage option when you run a database on an instance with the above criteria?
A. Amazon S3
B. Amazon EBS
C. AWS Storage Gateway
D. Amazon Glacier
Answer: B
Explanation:
Amazon EBS provides durable, block-level storage volumes that you can attach to a running Amazon EC2 instance. You can use Amazon EBS as a primary storage device for data that requires frequent and granular updates. For example, Amazon EBS is the recommended storage option when you run a database on an instance.

Q229. Can resource record sets in a hosted zone have a different domain suffix (for example, www.bIog. acme.com and www.acme.ca)?
A. Yes, it can have for a maximum of three different TLDs.
B. Yes
C. Yes, it can have depending on the TLD.
D. No
Answer: D
Explanation:
The resource record sets contained in a hosted zone must share the same suffix. For example, the exampIe.com hosted zone can contain resource record sets for www.exampIe.com and wvvw.aws.exampIe.com subdomains, but it cannot contain resource record sets for a www.exampIe.ca subdomain.

Q230. After setting up some EC2 instances you now need to set up a monitoring solution to keep track of these instances and to send you an email when the CPU hits a certain threshold. Which statement below best describes what thresholds you can set to trigger a CIoudWatch Alarm?
A. Set a target value and choose whether the alarm will trigger when the value is greater than (>), greater than or equal to (>=), less than (<), or less than or equal to (<=) that value.
B. Thresholds need to be set in IAM not CIoudWatch
C. Only default thresholds can be set you can't choose your own thresholds.
D. Set a target value and choose whether the alarm will trigger when the value hits this threshold
Answer: A
Explanation:
Amazon CIoudWatch is a monitoring service for AWS cloud resources and the applications you run on AWS. You can use Amazon CIoudWatch to collect and track metrics, collect and monitor log files, and set
alarms.
When you create an alarm, you first choose the Amazon CIoudWatch metric you want it to monitor. Next, you choose the evaluation period (e.g., five minutes or one hour) and a statistical value to measure (e.g., Average or Maximum).
To set a threshold, set a target value and choose whether the alarm will trigger when the value is greater than (>), greater than or equal to (>=), less than (<), or less than or equal to (<=) that value.
