Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q386-Q391):

NEW QUESTION # 386
A company is migrating a new application from an on-premises data center to a new VPC in the AWS Cloud.
The company has multiple AWS accounts and VPCs that share many subnets and applications.
The company wants to have fine-grained access control for the new application. The company wants to ensure that all network resources across accounts and VPCs that are granted permission to access the new application can access the application.

A. Use an AWS PrivateLink endpoint service to make the new application accessible to other VPCs.
Control access to the application by using an endpoint policy.
B. Deploy a transit gateway in the account that hosts the new application. Share the transit gateway with each account that needs to connect to the application. Update route tables in the VPC that hosts the new application and in the transit gateway to enable connectivity.
C. Use an Application Load Balancer (ALB) to expose the new application to the internet. Configure authentication and authorization processes to ensure that only specified VPCs can access the application.
D. Set up a VPC peering connection for each VPC that needs access to the new application VPC. Update route tables in each VPC to enable connectivity.

Answer: A

Explanation:
AWS PrivateLink is the most suitable solution for providing fine-grained access control while allowing multiple VPCs, potentially across multiple accounts, to access the new application. This approach offers the following advantages:
* Fine-grained control: Endpoint policies can restrict access to specific services or principals.
* No need for route table updates: Unlike VPC peering or transit gateways, AWS PrivateLink does not require complex route table management.
* Scalable architecture: PrivateLink scales to support traffic from multiple VPCs.
* Secure connectivity: Ensures private connectivity over the AWS network, without exposing resources to the internet.
Why Other Options Are Not Ideal:
* Option A:
* VPC peering is not scalable when connecting multiple VPCs or accounts.
* Route table management becomes complex as the number of VPCs increases.Not scalable.
* Option B:
* While transit gateways provide scalable VPC connectivity, they are not ideal for fine-grained access control.
* Transit gateways allow connectivity but do not inherently restrict access to specific applications.
Not ideal for fine-grained access control.
* Option D:
* Exposing the application through an ALB over the internet is not secure and does not align with the requirement to use private network resources.Security risk.

* AWS Networking Services Comparison:AWS Whitepaper - Networking Services

NEW QUESTION # 387
A company is deploying an application in three AWS Regions using an Application Load Balancer Amazon Route 53 will be used to distribute traffic between these Regions. Which Route 53 configuration should a solutions architect use to provide the MOST high-performing experience?

A. Create a CNAME record with a geoproximity policy.
B. Create an A record with a latency policy.
C. Create a CNAME record with a failover policy.
D. Create an A record with a geolocation policy.

Answer: B

Explanation:
To provide the most high-performing experience for the users of the application, a solutions architect should use a latency routing policy for the Route 53 A record. This policy allows Route 53 to route traffic to the AWS Region that provides the lowest possible latency for the users1. A latency routing policy can also improve the availability of the application, as Route 53 can automatically route traffic to another Region if the primary Region becomes unavailable2.

NEW QUESTION # 388
A company recently launched an e-commerce application that is running in eu-east-2 region, which strictly requires six EC2 instances running at all times. In that region, there are 3 Availability Zones (AZ) that you can use - eu-east-2a, eu-east-2b, and eu-east-2c.
Which of the following deployments provide 100% fault tolerance if any single AZ in the region becomes unavailable? (Select TWO.)

A. eu-east-2a with four EC2 instances, eu-east-2b with two EC2 instances, and eu-east-2c with two EC2 instances
B. eu-east-2a with two EC2 instances, eu-east-2b with two EC2 instances, and eu-east-2c with two EC2 instances
C. eu-east-2a with three EC2 instances, eu-east-2b with three EC2 instances, and eu-east-2c with three EC2 instances
D. eu-east-2a with two EC2 instances, eu-east-2b with four EC2 instances, and eu-east-2c with two EC2 instances
E. eu-east-2a with six EC2 instances, eu-east-2b with six EC2 instances, and eu-east-2c with no EC2 instances

Answer: C,E

Explanation:
Fault Tolerance is the ability of a system to remain in operation even if some of the components used to build the system fail. In AWS, this means that in the event of server fault or system failures, the number of running EC2 instances should not fall below the minimum number of instances required by the system for it to work properly. So if the application requires a minimum of 6 instances, there should be at least 6 instances running in case there is an outage in one of the Availability Zones or if there are server issues.

In this scenario, you have to simulate a situation where one Availability Zone became unavailable for each option and check whether it still has 6 running instances.
Hence, the correct answers are: eu-east-2a with six EC2 instances, eu-east-2b with six EC2 instances, and eu-east-2c with no EC2 instances and eu-east-2a with three EC2 instances, eu-east-2b with three EC2 instances, and eu-east-2c with three EC2 instances because even if one of the availability zones were to go down, there would still be 6 active instances.

NEW QUESTION # 389
A company is designing an application where users upload small files into Amazon S3. After a user uploads a file, the file requires one-time simple processing to transform the data and save the data in JSON format for later analysis.
Each file must be processed as quickly as possible after it is uploaded. Demand will vary. On some days, users will upload a high number of files. On other days, users will upload a few files or no files.
Which solution meets these requirements with the LEAST operational overhead?

A. Configure Amazon EventBridge (Amazon CloudWatch Events) to send an event to Amazon Kinesis Data Streams when a new file is uploaded. Use an AWS Lambda function to consume the event from the stream and process the data. Store the resulting JSON file in Amazon Aurora DB cluster.
B. Configure Amazon S3 to send an event notification to an Amazon Simple Queue Service (Amazon SQS) queue. Use an AWS Lambda function to read from the queue and process the data. Store the resulting JSON file in Amazon DynamoDB. Most Voted
C. Configure Amazon EMR to read text files from Amazon S3. Run processing scripts to transform the data. Store the resulting JSON file in an Amazon Aurora DB cluster.
D. Configure Amazon S3 to send an event notification to an Amazon Simple Queue Service (Amazon SQS) queue. Use Amazon EC2 instances to read from the queue and process the data. Store the resulting JSON file in Amazon DynamoDB.

Answer: B

Explanation:
Explanation
Amazon S3 sends event notifications about S3 buckets (for example, object created, object removed, or object restored) to an SNS topic in the same Region.
The SNS topic publishes the event to an SQS queue in the central Region.
The SQS queue is configured as the event source for your Lambda function and buffers the event messages for the Lambda function.
The Lambda function polls the SQS queue for messages and processes the Amazon S3 event notifications according to your application's requirements.

NEW QUESTION # 390
[Design Secure Architectures]
A company is migrating its on-premises PostgreSQL database to Amazon Aurora PostgreSQL. The on-premises database must remain online and accessible during the migration. The Aurora database must remain synchronized with the on-premises database.
Which combination of actions must a solutions architect take to meet these requirements? (Choose two.)

A. Create an AWS Database Migration Service (AWS DMS) replication server
B. Create an ongoing replication task.
C. Convert the database schema by using the AWS Schema Conversion Tool (AWS SCT).
D. Create a database backup of the on-premises database
E. Create an Amazon EventBridge (Amazon CloudWatch Events) rule to monitor the database synchronization

Answer: A,B

Explanation:
AWS Database Migration Service supports homogeneous migrations such as Oracle to Oracle, as well as heterogeneous migrations between different database platforms, such as Oracle or Microsoft SQL Server to Amazon Aurora. With AWS Database Migration Service, you can also continuously replicate data with low latency from any supported source to any supported target. For example, you can replicate from multiple sources to Amazon Simple Storage Service (Amazon S3) to build a highly available and scalable data lake solution. You can also consolidate databases into a petabyte-scale data warehouse by streaming data to Amazon Redshift. Learn more about the supported source and target databases.https://aws.amazon.com/dms/
