Amazon AWS Certified Solutions Architect - Associate (SAA-C03) Sample Questions (Q250-Q255):

NEW QUESTION # 250
A user is hosting a public website on AWS. The user wants to have the database and the app server on the AWS VPC. The user wants to setup a database that can connect to the Internet for any patch upgrade but cannot receive any request from the internet. How can the user set this up?

A. Setup DB in a local data center and use a private gateway to connect the application with DB.
B. Setup DB in a private subnet which is connected to the internet via NAT for outbound.
C. Setup DB in a private subnet with the security group allowing only outbound traffic.
D. Setup DB in a public subnet with the security group allowing only inbound data.

Answer: B

Explanation:
Explanation/Reference:
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the user to launch AWS resources into a virtual network that the user has defined. AWS provides two features that the user can use to increase security in VPC: security groups and network ACLs. When the user wants to setup both the DB and App on VPC, the user should make one public and one private subnet. The DB should be hosted in a private subnet and instances in that subnet cannot reach the internet. The user can allow an instance in his VPC to initiate outbound connections to the internet but prevent unsolicited inbound connections from the internet by using a Network Address Translation (NAT) instance.

NEW QUESTION # 251
A Solutions Architect is designing a solution to monitor weather changes by the minute. The frontend application is hosted on Amazon EC2 instances. The backend must be scalable to a virtually unlimited size, and data retrieval must occur with minimal latency.
Which AWS service should the Architect use to store the data and achieve these requirements?

A. Amazon DynamoDB
B. Amazon EBS
C. Amazon RDS
D. Amazon S3

Answer: D

NEW QUESTION # 252
A company runs an application on Amazon EC2 instances. that are part of an Auto Scaling group Traffic to the application increases substantially during business hours. A solutions architect needs to implement an Auto Scaling policy that addresses user latency concerns during periods of high traffic. The company does not want to provision more compute man is necessary What should me solutions architect do to meet these requirements?

A. Configure a scheduled scaling policy that launches additional EC2 instances during business hours
B. Configure dynamic step or simple scaling policies with Ama7on CloudWatch alarms to add and remove EC2 instances based on alarm status
C. Configure a dynamic target tracking scaling policy with the appropriate scaling metric
D. Configure a predictive scaling policy with the appropriate scaling metric.

Answer: A

NEW QUESTION # 253
A company runs an application on an Amazon EC2 instances backed by Amazon Elastic Block Store (Amazon EBS). The instances needs to be available for 12 hours daily. The company wants to save costs by making the instance outside the window required for the application. However, the contents of the memory must be preserved whenever the instance is unavailable.
What should a solutions architect do lo meet this requirement?

A. Stop the instance outside the application's availability window Start up the instance again when required
B. Use Auto Scaling to scale down the instance outside the application's availability window Scale up the instance when required.
C. Terminate the instance outside the application's availability window Launch the instance by using a preconfigured Amazon Machine Image (AMI) when required
D. Hibernate the instance outside the application's availability window Start up the instance again when required

Answer: A

NEW QUESTION # 254
You are responsible for a web application that consists of an Elastic Load Balancing (ELB) load balancer
in front of an Auto Scaling group of Amazon Elastic Compute Cloud (EC2) instances. For a recent
deployment of a new version of the application, a new Amazon Machine Image (AMI) was created, and
the Auto Scaling group was updated with a new launch configuration that refers to this new AMI. During
the deployment, you received complaints from users that the website was responding with errors. All
instances passed the ELB health checks.
What should you do in order to avoid errors for future deployments? (Choose 2 answer)

A. Set the Elastic Load Balancing health check configuration to target a part of the application that fully
tests application health and returns an error if the tests fail.
B. Add an Elastic Load Balancing health check to the Auto Scaling group. Set a short period for the health
checks to operate as soon as possible in order to prevent premature registration of the instance to the
load balancer.
C. Create a new launch configuration that refers to the new AMI, and associate it with the group. Double
the size of the group, wait for the new instances to become healthy, and reduce back to the original size.
If new instances do not become healthy, associate the previous launch configuration.
D. Enable EC2 instance CloudWatch alerts to change the launch configuration AMI to the previous one.
Gradually terminate instances that are using the new AMI.
E. Increase the Elastic Load Balancing Unhealthy Threshold to a higher value to prevent an unhealthy
instance from going into service behind the load balancer.

Answer: A,C
