Question 49

A user is creating a PIOPS volume. What is the maximum ratio the user should configure between PIOPS and the volume size?

A. 5

B. 10

C. 20

D. 30

Correct Answer:D
Provisioned IOPS volumes are designed to meet the needs of I/O-intensive workloads, particularly database workloads that are sensitive to storage performance and consistency in random access I/O throughput. A provisioned IOPS volume can range in size from 10 GB to 1 TB and the user can provision up to 4000 IOPS per volume.
The ratio of IOPS provisioned to the volume size requested can be a maximum of 30; for example, a volume with 3000 IOPS must be atleast 100 GB.

Question 50

An organization is making software for the CIA in US

A. CIA agreed to host the application on AWS but ina secure environmen

B. The organization is thinking of hosting the application on the AWS GovC|oud regio

C. Which of the below mentioned difference is not correct when the organization is hosting on the AWS GovCIoud in comparison with the AWS standard region?

D. The billing for the AWS GovCLoud will be in a different account than the Standard AWS account.

E. GovCIoud region authentication is isolated from Amazon.com.

F. Physical and logical administrative access only to U.

G. persons.

H. It is physically isolated and has logical network isolation from all the other region

Correct Answer:A
AWS GovCIoud (US) is an isolated AWS region designed to allow U.S. government agencies and customers to move sensitive workloads into the cloud by addressing their specific regulatory and compliance requirements. The AWS GovCIoud (US) Region adheres to the U.S. International Traffic in
Arms Regulations (ITAR) requirements. It has added advantages, such as: Restricting physical and logical administrative access to U.S. persons only
There will be a separate AWS GovCIoud (US) credentials, such as access key and secret access key than the standard AWS account
The user signs in with the IAM user name and password
The AWS GovCIoud (US) Region authentication is completely isolated from Amazon.com
If the organization is planning to host on EC2 in AWS GovCIoud then it will be billed to standard AWS account of organization since AWS GovCIoud billing is linked with the standard AWS account and is not be billed separately

Question 51

Your company hosts a social media site supporting users in multiple countries. You have been asked to provide a highly available design tor the application that leverages multiple regions tor the most recently accessed content and latency sensitive portions of the wet) site The most latency sensitive component of the application involves reading user preferences to support web site personalization and ad selection. In addition to running your application in multiple regions, which option will support this appIication’s requirements?

A. Serve user content from S3. CIoudFront and use Route53 latency-based routing between ELBs in each region Retrieve user preferences from a local DynamoDB table in each region and leverage SQS to capture changes to user preferences with SOS workers for propagating updates to each table.

B. Use the S3 Copy API to copy recently accessed content to multiple regions and serve user content from S3. C|oudFront with dynamic content and an ELB in each region Retrieve user preferences from an EIasticCache cluster in each region and leverage SNS notifications to propagate user preference changes to a worker node in each region.

C. Use the S3 Copy API to copy recently accessed content to multiple regions and serve user content from S3 CIoudFront and Route53 latency-based routing Between ELBs In each region Retrieve user preferences from a DynamoDB table and leverage SQS to capture changes to user preferences with SOS workers for propagating DynamoDB updates.

D. Serve user content from S3. C|oudFront with dynamic content, and an ELB in each region Retrieve user preferences from an EIastiCache cluster in each region and leverage Simple Workflow (SWF) to manage the propagation of user preferences from a centralized OB to each EIastiCache cluster.

Correct Answer:A

Question 52

AWS has launched T2 instances which come with CPU usage credit. An organization has a requirement which keeps an instance running for 24 hours. However, the organization has high usage only during 11 AM to 12 PM. The organization is planning to use a T2 small instance for this purpose.
If the organization already has multiple instances running since Jan 2012, which of the below mentioned options should the organization implement while launching a T2 instance?

A. The organization must migrate to the EC2-VPC platform first before launching a T2 instance.

B. While launching a T2 instance the organization must create a new AWS account as this account does not have the EC2-VPC platform.

C. Create a VPC and launch a T2 instance as part of one of the subnets of that VPC.

D. While launching a T2 instance the organization must select EC2-VPC as the platform.

Correct Answer:C
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. The user can create subnets as per the requirement within a VPC. The AWS account provides two platforms:
EC2-CLASSIC and EC2-VPC, depending on when the user has created his AWS account and which regions he is using. If the user has created the AWS account after 2013-12-04, it supports only EC2-VPC. In this scenario, since the account is before the required date the supported platform will be
EC2-CLASSIC. It is required that the organization creates a VPC as the T2 instances can be launched only as a part of VPC.

Question 53

A read only news reporting site with a combined web and application tier and a database tier that receives large and unpredictable traffic demands must be able to respond to these traffic fluctuations automatically. What AWS services should be used meet these requirements?

A. Stateless instances for the web and application tier synchronized using EIastiCache Memcached in an autoscaimg group monitored with CIoudWatch and RDS with read replicas.

B. Stateful instances for the web and application tier in an autoscaling group monitored with CIoudWatch and RDS with read replicas.

C. Stateful instances for the web and application tier in an autoscaling group monitored with CIoudWatc

D. And multi-AZ RDS.

E. Stateless instances for the web and application tier synchronized using EIastiCache Memcached in an autoscaling group monitored with CIoudWatch and multi-AZ RDS.

Correct Answer:A
