An enterprise wants to build an application for selling concert tickets, with a web layer and an
application layer. Which Amazon service should be used so ticket orders are not lost if the application
layer fails? - ANSWER-SQS
To comply with its disaster recovery requirements, an enterprise is required to store copies of all data
in a specific Amazon S3 bucket in an additional Region. How should this requirement be fulfilled? -
ANSWER-Enable versioning for the source bucket and configure Cross-Region Replication
An application is deployed in the us-west-1 and eu-west-1 Regions, and the users should be sent to
the Region with the fastest response for them, regardless of their location. The solution must
minimize administrative effort. Which routing policy should be used? - ANSWER-Latency
A notification is sent to an Amazon SQS queue when an object is uploaded to an Amazon S3 bucket.
An Amazon ECS cluster processes messages from the queue. The required queue size fluctuates
based on the number of incoming messages and the processing speed. The company needs to design
a scaling strategy for auto scaling that will minimize the queue size. Which metric should be used for
auto scaling to minimize the queue size? - ANSWER-Amazon SQS messages
A company is building a high-performance computing (HPC) clustered workload on AWS using EC2
instances and is looking for a fully managed, shared storage solution for this workload. Once the HPC
portion of the data processing is complete, the company would like to serve the resulting data
directly on the internet. Which Amazon service would be the most cost-effective solution for these
requirements? - ANSWER-FSx for Lustre
Which Amazon storage class monitors data usage and moves data to the most cost-effective
location? - ANSWER-S3 Intelligent-Tiering
Which tool reduces time and costs by allowing a customer to automate the creation and track the
changes of entire resource environments? - ANSWER-CloudFormation
, An organization needs a low-cost system to host its website. Which elastic compute configuration
meets the requirement at the least cost? - ANSWER-A general purpose instance with a hard disk
drive
A development team needs a system to run recurring benchmark tests for an artificial intelligence
application. To remove variability from one test to the other, the storage will be reinitialized for each
test. Which elastic compute configuration meets the requirements while minimizing cost and
administration time? - ANSWER-An accelerated computing instance with an instance store
A client wants to use a managed service to replace an EC2 instance that currently hosts a shared big
data analytics store, accessible via the NFS protocol. The managed service must provide read-after-
write consistency and low latency for read and write operations. Which Amazon service should this
client choose? - ANSWER-EFS
A client wants to use a managed service to replace an EC2 instance that currently hosts a Windows
Server file server, with shares accessible via the SMB protocol. The managed service must provide
support for Active Directory and Distributed File System. Which Amazon service should this client
choose? - ANSWER-FSx
When users consume data from an Amazon S3 bucket, a company wants to reduce transfer costs by
enforcing that the content is delivered using CloudFront. Which feature should be configured? -
ANSWER-Origin access identity
A company needs to store backup data in Amazon S3. There are no restrictions on where the data
can be stored geographically. The company wants to find the lowest cost for storage and transfers.
Which boundary should this company consider comparing storage fees at? - ANSWER-Region
A client wants to implement redundant network access to EC2 instances with automatic failover in
case the existing AWS Direct Connect connection fails. The solution must minimize cost. Which
network access option should this client use? - ANSWER-Site-to-Site VPN
A client has 100 on-premises locations in the northwestern United States. Each location has network
access to the same Amazon VPCs in the US West AWS Region via Internet Protocol Security (IPSec)
tunnels. The client plans to create 500 Amazon VPCs in the same Region. The client needs to ensure
all Amazon VPCs will be accessible from each of its on-premises locations. The solution must
