Question #21 Topic 1

An ecommerce company wants to design a highly available application that will be hosted on multiple Amazon EC2 instances. How should the company deploy the EC2 instances to meet these requirements?

A . cross multiple edge locations
B . Across multiple VPCs
C . Across multiple Availability Zones
D . Across multiple AWS accounts

Suggested Answer: C
NOTE: Answer is C. Deploying across multiple Availability Zones helps achieve high availability as it protects the application from the failure of a single location. VPCs, AWS accounts, or edge locations aren't specifically designed for high availability.

Question #22 Topic 1

A company wants to minimize network latency between its Amazon EC2 instances. The EC2 instances do not need to be highly available. Which solution meets these requirements?

A . Use EC2 instances in a single vailability Zone.
B . Use Amazon CloudFront as the database for the EC2 instances.
C . Use E2 instances in the same edge location and the same Availability Zone.
D . Use EC2 instances in the same edge location and the same AWS Region.

Suggested Answer: A
NOTE: Answer is A. The question is about minimizing network latency between EC2 instances. Since high availability is not a requirement, using EC2 instances in a single Availability Zone is the most appropriate solution. This is because instances in the same availability zone will have the lowest latency. Other options such as using CloudFront or different edge locations and regions do not specifically cater to minimizing latency between EC2 instances.

Question #23 Topic 1

A . mazon Elastic Block Store (mazon EBS)
B . Amazon S3
C . Amazon Elastic File System (Amazon EFS)
D . AWS Storage Gateway

Suggested Answer: B

It's designed for durability, and it stores files for the long term and encrypts them to provide security. Moreover, it also provides direct access over the internet and it can be very cost-effective based on the storage class chosen.

C . AWS credits
D . Cost allocation tags

Suggested Answer: B
NOTE: Answer is B. Consolidated billing is a feature used when managing costs across multiple Amazon Web Services (AWS) accounts. It allows you to combine usage from all accounts in your organization. This leads to a higher aggregate usage level, which often results in lower prices due to volume pricing.

Question #25 Topic 1

Which AWS service provides the capability to view end-to-end performance metrics and troubleshoot distributed applications?

A . WS Cloud9
B . AWS CodeStar
C . AWS loud Map
D . AWS X-Ray

Suggested Answer: D
NOTE: Answer is D. AWS X-Ray helps developers analyze and debug distributed applications, such as those developed using a microservices architecture. So it's better suited to provide the capability to view end-to-end performance metrics and troubleshoot distributed applications.
