A company's HTTP application is behind a Network Load Balancer (NLB). The NLB's target group
is configured to use an Amazon EC2 Auto Scaling group with multiple EC2 instances that run the
web service.
The company notices that the NLB is not detecting HTTP errors for the application. These errors
require a manual restart of the EC2 instances that run the web service. The company needs to
improve the application's availability without writing custom scripts or code.
What should a solutions architect do to meet these requirements?
A. Enable HTTP health checks on the NLB. supplying the URL of the company's application.
B. Add a cron job to the EC2 instances to check the local application's logs once each minute.
If HTTP errors are detected, the application will restart.
C. Replace the NLB with an Application Load Balancer.
Enable HTTP health checks by supplying the URL of the company's application.

A company runs a shopping application that uses Amazon DynamoDB to store customer
information. In case of data corruption, a solutions architect needs to design a solution that
meets
a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 1 hour.
,What should the solutions architect recommend to meet these requirements?
A. Configure DynamoDB global tables.
For RPO recovery, point the application to a different AWS Region.
B. Configure DynamoDB point-in-time recovery.
For RPO recovery, restore to the desired point in time.
C. Export the DynamoDB data to Amazon S3 Glacier on a daily basis.
For RPO recovery, import the data from S3 Glacier to DynamoDB.
D. Schedule Amazon Elastic Block Store (Amazon EBS) snapshots for the DynamoDB table every
15 minutes.
For RPO recovery, restore the DynamoDB table by using the EBS snapshot. - ✔✔B

A company runs a photo processing application that needs to frequently upload and download
pictures from Amazon S3 buckets that are located in the same AWS Region. A solutions
architect
has noticed an increased cost in data transfer fees and needs to implement a solution to reduce
these costs.
How can the solutions architect meet this requirement?
A. Deploy Amazon API Gateway into a public subnet and adjust the route table to route S3 calls
through It.
B. Deploy a NAT gateway into a public subnet and attach an end point policy that allows access
to
the S3 buckets.
C. Deploy the application Into a public subnet and allow it to route through an internet gateway
to access the S3 Buckets
,D. Deploy an S3 VPC gateway endpoint into the VPC and attach an endpoint policy that allows
access to the S3 buckets. - ✔✔D

A company recently launched Linux-based application instances on Amazon EC2 in a private
subnet and launched a Linux-based bastion host on an Amazon EC2 instance in a public subnet
of a VPC. A solutions architect needs to connect from the on-premises network, through the
company's internet connection, to the bastion host, and to the application servers. The
solutions
architect must make sure that the security groups of all the EC2 instances will allow that access.
Which combination of steps should the solutions architect take to meet these requirements?
(Choose two.)
A. Replace the current security group of the bastion host with one that only allows inbound
access
from the application instances
B. Replace the current security group of the bastion host with one that only allows inbound
access
from the internal IP range for the company
C. Replace the current security group of the bastion host with one that only a - ✔✔CD

A solutions architect is designing a two-tier web application. The application consists of a
public-
facing web tier hosted on Amazon EC2 in public subnets. The database tier consists of Microsoft
SQL Server running on Amazon EC2 in a private subnet. Security is a high priority for the
company.
How should security groups be configured in this situation? (Choose two.)
, A. Configure the security group for the web tier to allow inbound traffic on port 443 from
0.0.0.0/0.
B. Configure the security group for the web tier to allow outbound traffic on port 443 from
0.0.0.0/0.
C. Configure the security group for the database tier to allow inbound traffic on port 1433 from
the
security group for the web tier.
D. Configure the security group for the database tier to allow outbound traffic on ports 443 and
1433 to the security group for the web tier.
E. Configure the security group for the database tier to allow inbound tr - ✔✔AC

A company wants to move a multi-tiered application from on premises to the AWS Cloud to
improve the application's performance. The application consists of application tiers that
communicate with each other by way of RESTful services. Transactions are dropped when one
tier becomes overloaded. A solutions architect must design a solution that resolves these issues
and modernizes the application.
Which solution meets these requirements and is the MOST operationally efficient?
A. Use Amazon API Gateway and direct transactions to the AWS Lambda functions as the
application layer.
Use Amazon Simple Queue Service (Amazon SQS) as the communication layer between
application services.
B. Use Amazon CloudWatch metrics to analyze the application performance history to
determine
the server's peak utilization during the performance failures.
