Amazon AWS Certified Solutions Architect - Professional Sample Questions (Q356-Q361):

NEW QUESTION # 356
A media company has a static web application that is generated programmatically. The company has a build pipeline that generates HTML content that is uploaded to an Amazon S3 bucket served by Amazon CloudFront. The build pipeline runs inside a Build Account. The S3 bucket and CloudFront distribution are in a Distribution Account. The build pipeline uploads the files to Amazon S3 using an 1AM role in the Build Account. The S3 bucket has a bucket policy that only allows CloudFront to read objects using an origin access identity (OAI). During testing, all attempts to access the application using the CloudFront URL result in an HTTP 403 Access Denied response.
What should a solutions architect suggest to the company to allow access the objects in Amazon S3 through CloudFront?

A. Modify the S3 upload process in the Build Account to add the bucket-owner-full-control ACL to the objects at upload.
B. Create a new cross-account 1AM role in the Distribution Account with write access to the S3 bucket.
Modify the build pipeline to assume this role to upload the files to the Distribution Account.
C. Modify the S3 upload process in the Build Account to set the object owner to the Distribution Account.
D. Create a new 1AM role in the Distribution Account with read access to the S3 bucket. Configure CloudFront to use this new role as its OAI. Modify the build pipeline to assume this role when uploading files from the

Answer: B

NEW QUESTION # 357
A company has VPC flow logs enabled for its NAT gateway. The company is seeing Action = ACCEPT for inbound traffic that comes from public IP address
198.51.100.2 destined for a private Amazon EC2 instance.
A solutions architect must determine whether the traffic represents unsolicited inbound connections from the internet. The first two octets of the VPC CIDR block are 203.0.
Which set of steps should the solutions architect take to meet these requirements?

A. Open the Amazon CloudWatch console. Select the log group that contains the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as "like 198.51.100.2" and the source address set as "like 203.0". Run the stats command to filter the sum of bytes transferred by the source address and the destination address.
B. Open the AWS CloudTrail console. Select the log group that contains the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as "like 198.51.100.2" and the source address set as "like 203.0". Run the stats command to filter the sum of bytes transferred by the source address and the destination address.
C. Open the AWS CloudTrail console. Select the log group that contains the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as "like 203.0" and the source address set as "like 198.51.100.2". Run the stats command to filter the sum of bytes transferred by the source address and the destination address.
D. Open the Amazon CloudWatch console. Select the log group that contains the NAT gateway's elastic network interface and the private instance's elastic network interface. Run a query to filter with the destination address set as "like 203.0" and the source address set as "like 198.51.100.2". Run the stats command to filter the sum of bytes transferred by the source address and the destination address.

NEW QUESTION # 358
A company has developed a mobile game. The backend for the game runs on several virtual machines located in an on-premises data center. The business logic is exposed using a REST API with multiple functions. Player session data is stored in central file storage. Backend services use different API keys for throttling and to distinguish between live and test traffic.
The load on the game backend varies throughout the day. During peak hours, the server capacity is not sufficient. There are also latency issues when fetching player session data. Management has asked a solutions architect to present a cloud architecture that can handle the game's varying load and provide low-latency data access. The API model should not be changed.
Which solution meets these requirements?

A. Implement the REST API using an Application Load Balancer (ALB). Run the business logic in AWS Lambda. Store player session data in Amazon DynamoDB with on-demand capacity.
B. Implement the REST API using Amazon API Gateway. Run the business logic in AWS Lambda. Store player session data in Amazon DynamoDB with on- demand capacity.
C. Implement the REST API using a Network Load Balancer (NLB). Run the business logic on an Amazon EC2 instance behind the NLB. Store player session data in Amazon Aurora Serverless.
D. Implement the REST API using AWS AppSync. Run the business logic in AWS Lambda. Store player session data in Amazon Aurora Serverless.

Answer: B

NEW QUESTION # 359
You need a persistent and durable storage to trace call activity of an IVR (Interactive Voice Response) system. Call duration is mostly in the 2-3 minutes timeframe. Each traced call can be either active or terminated. An external application needs to know each minute the list of currently active calls. Usually there are a few calls/second, but once per month there is a periodic peak up to 1000 calls/second for a few hours. The system is open 24/7 and any downtime should be avoided. Historical data is periodically archived to files. Cost saving is a priority for this project.
What database implementation would better fit this scenario, keeping costs as low as possible?

A. Use RDS Multi-AZ with a "CALLS" table and an indexed "STATE" field that can be equal to
"ACTIVE" or 'TERMINATED".
In this way the SQL query is optimized by the use of the Index.
B. Use RDS Multi-AZ with two tables, one for "ACTIVE_CALLS" and one for
"TERMINATED_CALLS".
In this way the "ACTIVE_CALLS" table is always small and effective to access.
C. Use DynamoDB with a "Calls" table and a Global Secondary Index on a "IsActive" attribute that is present for active calls only.
In this way the Global Secondary Index is sparse and more effective.
D. Use DynamoDB with a "Calls" table and a Global Secondary Index on a "State" attribute that can equal to "active" or "terminated".
In this way the Global Secondary Index can be used for all items in the table.

Answer: C

Explanation:
https://aws.amazon.com/dynamodb/faqs/
Q: Can a global secondary index key be defined on non-unique attributes?
Yes. Unlike the primary key on a table, a GSI index does not require the indexed attributes to be unique.
Q: Are GSI key attributes required in all items of a DynamoDB table?
No. GSIs are sparse indexes. Unlike the requirement of having a primary key, an item in a DynamoDB table does not have to contain any of the GSI keys. If a GSI key has both hash and range elements, and a table item omits either of them, then that item will not be indexed by the corresponding GSI. In such cases, a GSI can be very useful in efficiently locating items that have an uncommon attribute.

NEW QUESTION # 360

A. Amazon RDS for PostgreSQL.
B. Amazon ElastiCache for Redis
C. Amazon RDS for MySQL
D. Amazon ElastiCache for Memcached
