Argument5
A Solutions Architect is designing the storage layer for a production relational database. The
database will run on Amazon EC2. The database is accessed by an application that performs intensive
reads and writes, so the database requires the LOWEST random I/O latency.
Which data storage method fulfills the above requirements?
Selecione a resposta
1 resposta correta
A.
Store data in a filesystem backed by Amazon Elastic File System (EFS).
B.
Store data in Amazon S3 and use a third-party solution to expose Amazon S3 as a filesystem to the
database server.
C.
Store data in Amazon Dynamo DB and emulate relational database semantics.
D.
Stripe data across multiple Amazon EBS volumes using RAID 0.

Questionário

4/10
Argument2
A news organization plans to migrate their 20 TB video archive to AWS. The files are rarely
accessed, but when they are, a request is made in advance and a 3 to 5-hour retrieval time frame is
acceptable. However, when there is a breaking news story, the editors require access to archived
footage within minutes.
Which storage solution meets the needs of this organization while providing the LOWEST cost of
storage?
Selecione a resposta
1 resposta correta
A.
Store the archive in Amazon S3 Reduced Redundancy Storage.
B.
Store the archive in Amazon Glacier and use standard retrieval for all content.
C.
Store the archive in Amazon Glacier and pay the additional charge for expedited retrieval when
needed.
D.
Store the archive in Amazon S3 with a lifecycle policy to move this to S3 Infrequent Access after 30
days.

Argument4
A Solutions Architect must select the most cost-efficient architecture for a service that
responds to web requests. These web requests are small and query a DynamoDB table.
The request rate ranges from zero to several hundred each second, without any predictable patterns.
What is the MOST cost-efficient architecture for this service?
Selecione a resposta
1 resposta correta
A.
Network Load Balancer/Amazon EC2
B.
Application Load Balancer/Amazon ECS

Questionário

6/10
Argument0
An application uses an Amazon SQS queue as a transport mechanism to deliver data to a
group of EC2 instances for processing. The application owner wants to add a mechanism to archive
the incoming data without modifying application code on the EC2 instances.
How can this application be re-architected to archive the data without modifying the processing
instances?
Selecione a resposta
1 resposta correta
A.
Trigger a Lambda function by using Amazon CloudWatch Events to retrieve messages from the
SQS queue and archive to Amazon S3.
B.
Use an Amazon SNS topic to fan out the data to the SQS queue in addition to a Lambda function
that records the data to an S3 bucket.
C.
Set up an Amazon Kinesis Data Stream so that multiple instances can receive data.
Add a separate EC2 instance that is configured to archive all data it receives.
D.
Write the data to an S3 bucket, and use an SQS queue for S3 event notifications to tell the
instances where to retrieve the data.

Questionário

7/10
Argument3
The application tier for a workload runs on EC2 instances that are unevenly distributed across
two Availability Zones. The instances are behind a Network Load Balancer and are accessed through
layer 4 TCP connections.
The instances in the lesser populated Availability Zone are failing as the result of high CPU utilization.
Which configuration change can help mitigate the issue?
Selecione a resposta
1 resposta correta
A.
Modify the Network Load Balancer to enable sticky sessions
B.
Modify the Network Load Balancer to enable cross-zone load balancing.
C.
Switch to using an Application Load Balancer and enable sticky sessions.
D.
Switch to using an Application Load Balancer and enable cross-zone load balancing.

Questionário

8/10
Argument1
A company wants to migrate a three-tier web application to AWS. The company wants to
control the placement of the instances and have visibility into underlying sockets and cores for
licensing purposes.

1 resposta correta
A.
EC2 Reserved Instances
B.
EC2 Spot Instances
C.
EC2 Dedicated Hosts
D.
EC2 Placement Groups
