1. 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?: SQS
2. 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?: Enable
versioning for the source bucket and configure Cross-Region Replication
3. 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?: Latency
4. 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?: Amazon SQS messages
5. A company hosts a website from two EC2 instances. Users access the
website through an Elastic Load Balancer (ELB). The company needs to
ensure the website is highly available if one or more of the EC2 instances
are unavailable. Which solution should this company use?: Configure the
ELB to implement Auto
Scaling based on health checks
6. A company plans to migrate a legacy application to EC2 with no
modifications to the application. The company hopes to add modern cloud
features to immediately respond to changing needs. Which cloud feature
will achieve this goal?: Auto scaling
7. A company plans to migrate a legacy application to EC2 with no
modifications to the application. The application has regular seasonal
increases in demand, and it must automatically adapt to these needs. Which
scaling option should be included in the migration?: Scheduled
8. A company plans to migrate a legacy application to Amazon EC2 with
no modifications to the application. The application constantly changes
demands with no patterns, and it must automatically adapt to these needs.
Which scaling option should be included in the migration?: Dynamic

9. A company plans to migrate a legacy application to Amazon EC2 with
no modifications to the application. Once the application has completed a
trial in the cloud, the company needs to use machine learning algorithms to
adapt the application to changing demands. Which scaling option should be
used?: Predictive
10. A web application uses a web server with a separate database server.
The database provides results to the web server. Users report long delays in
receiving their results. Logs reveal that the CPU utilization metric for the
web server consistently reaches 100%. Performance metrics for the
database are nominal. How can the response time be improved?: By scaling
the web server layer through the addition of web servers
11. An administrator is concerned that a consumer may fail and not receive
every message immediately. The administrator chooses to use Amazon
Simple Queue Service (Amazon SQS) to ensure the consumer will be able to
receive all the messages. Which mechanism does Amazon SQS use to allow
the consumer to receive a queued message after the consumer is restored?:
Pull 12. How should an administrator recover queued messages from
Amazon
Simple Queue Service (Amazon SQS) if the consumer fails?: Pull the queue
after the application is restored
13. An application has the following storage requirements:
Information is stored in multiple tables on a single server.
Master records can be linked to zero or more child records by using shared
keys.
The solution must support up to 15 additional replicas.
Which solution should be used?: Amazon Aurora
14. A Linux application needs to use a shared file system. Which solution
should be used?: Amazon EFS
15. A company has data stored on premises and needs to identify a solution
that stores snapshots of the local data in AWS. Which solution should be
used?: Stored Volume Gateway
16. How should end-to-end confidentiality be achieved for data stored in an
Amazon S3 bucket?: By setting default encryption and a policy to enforce
HTTPS connections on the bucket
17. A client plans to use the internet to copy a large amount of data from an
on-premises Network File System (NFS) store to Amazon S3. Which
service will transfer the data in the shortest time?: Amazon Web Services
DataSync 18. A client has an existing on-premises tape backup
