● #202
A company wants to host a web application on AWS that will
communicate to a database within a VPC. The application should be
highly available.What should a solutions architect recommend?
A. Create two Amazon EC2 instances to host the web servers behind a
load balancer, and then deploy the database on a large instance.
B. Deploy a load balancer in multiple Availability Zones with an Auto
Scaling group for the web servers, and then deploy Amazon RDS in
multiple Availability Zones.
C. Deploy a load balancer in the public subnet with an Auto Scaling
group for the web servers, and then deploy the database on an Amazon
EC2 instance in the private subnet.
D. Deploy two web servers with an Auto Scaling group, configure a
domain that points to the two web servers, and then deploy a database
architecture in multiple Availability Zones. (B)
● #203
A company's packaged application dynamically creates and returns
single-use text files in response to user requests. The company is using
Amazon CloudFront for distribution, but wants to further reduce data
,transfer costs. The company cannot modify the application's source
code.What should a solutions architect do to reduce costs?
A. Use Lambda@Edge to compress the files as they are sent to users.
B. Enable Amazon S3 Transfer Acceleration to reduce the response
times.
C. Enable caching on the CloudFront distribution to store generated files
at the edge.
D. Use Amazon S3 multipart uploads to move the files to Amazon S3
before returning them to users. (A)
● #204
A database is on an Amazon RDS MySQL 5.6 Multi-AZ DB instance
that experiences highly dynamic reads. Application developers notice a
significant slowdown when testing read performance from a secondary
AWS Region. The developers want a solution that provides less than 1
second of read replication latency.What should the solutions architect
recommend?
A. Install MySQL on Amazon EC2 in the secondary Region.
B. Migrate the database to Amazon Aurora with cross-Region replicas.
C. Create another RDS for MySQL read replica in the secondary
Region.
D. Implement Amazon ElastiCache to improve database query
performance. (B)
● #205
, A company is planning to deploy an Amazon RDS DB instance running
Amazon Aurora. The company has a backup retention policy
requirement of 90 days.Which solution should a solutions architect
recommend?
A. Set the backup retention period to 90 days when creating the RDS
DB instance.
B. Configure RDS to copy automated snapshots to a user-managed
Amazon S3 bucket with a lifecycle policy set to delete after 90 days.
C. Create an AWS Backup plan to perform a daily snapshot of the RDS
database with the retention set to 90 days. Create an AWS Backup job to
schedule the execution of the backup plan daily.
D. Use a daily scheduled event with Amazon CloudWatch Events to
execute a custom AWS Lambda function that makes a copy of the RDS
automated snapshot. Purge snapshots older than 90 days (B)
● #206
A company currently has 250 TB of backup files stored in Amazon S3 in
a vendor's proprietary format. Using a Linux-based software application
provided by the vendor, the company wants to retrieve files from
Amazon S3, transform the files to an industry-standard format, and re-
upload them to Amazon S3. The company wants to minimize the data
transfer charges associated with this conversation.What should a
solutions architect do to accomplish this?
A. Install the conversion software as an Amazon S3 batch operation so
the data is transformed without leaving Amazon S3.
