- (Exam Topic 2)
A company that designs multiplayer online games wants to expand its user base outside of Europe. The company transfers a significant amount of UDP traffic to Keep all the live and interactive sessions of the games The company has plans for rapid expansion and wants to build its architecture to provide an optimized online experience to its users
Which architecture will meet these requirements with the LOWEST latency for users''

A. Set up a Multi-AZ environment in a single AWS Region Use Amazon CloudFront to cache user sessions
B. Set up environments in multiple AWS Regions Create an accelerator in AWS Global Accelerator, and add endpoints from different Regions to it
C. Set up environments in multiple AWS Regions Use Amazon Route 53. and select latency-based routing
D. Set up a Multi-AZ environment in a single AWS Regio
E. Use AWS Lambda@Edge to update sessions closer to the users

Correct Answer:B

Question 57

- (Exam Topic 1)
An e-commerce company is revamping its IT infrastructure and is planning to use AWS services. The company's CIO has asked a solutions architect to design a simple, highly available, and loosely coupled order processing application. The application is responsible (or receiving and processing orders before storing them in an Amazon DynamoDB table. The application has a sporadic traffic pattern and should be able to scale during markeling campaigns to process the orders with minimal delays.
Which of the following is the MOST reliable approach to meet the requirements?

A. Receive the orders in an Amazon EC2-hosted database and use EC2 instances to process them.
B. Receive the orders in an Amazon SOS queue and trigger an AWS Lambda function lo process them.
C. Receive the orders using the AWS Step Functions program and trigger an Amazon ECS container lo process them.
D. Receive the orders in Amazon Kinesis Data Streams and use Amazon EC2 instances to process them.

Correct Answer:B
Q: How does Amazon Kinesis Data Streams differ from Amazon SQS?
Amazon Kinesis Data Streams enables real-time processing of streaming big data. It provides ordering of records, as well as the ability to read and/or replay records in the same order to multiple Amazon Kinesis Applications. The Amazon Kinesis Client Library (KCL) delivers all records for a given partition key to the same record processor, making it easier to build multiple applications reading from the same Amazon Kinesis data stream (for example, to perform counting, aggregation, and filtering).

Question 58

- (Exam Topic 2)
A company has created an OU in AWS Organizations for each of its engineering teams Each OU owns multiple AWS accounts. The organization has hundreds of AWS accounts A solutions architect must design a solution so that each OU can view a breakdown of usage costs across its AWS accounts. Which solution meets these requirements?

A. Create an AWS Cost and Usage Report (CUR) for each OU by using AWS Resource Access Manager Allow each team to visualize the CUR through an Amazon QuickSight dashboard.
B. Create an AWS Cost and Usage Report (CUR) from the AWS Organizations management account- Allow each team to visualize the CUR through an Amazon QuickSight dashboard
C. Create an AWS Cost and Usage Report (CUR) in each AWS Organizations member account Allow eachteam to visualize the CUR through an Amazon QuickSight dashboard.
D. Create an AWS Cost and Usage Report (CUR) by using AWS Systems Manager Allow each team to visualize the CUR through Systems Manager OpsCenter dashboards

Correct Answer:B

Question 59

- (Exam Topic 1)
A team collects and routes behavioral data for an entire company The company runs a Multi-AZ VPC environment with public subnets, private subnets, and in internet gateway Each public subnet also contains a NAT gateway Most of the company's applications read from and write to Amazon Kinesis Data Streams. Most of the workloads am in private subnets.
A solutions architect must review the infrastructure The solutions architect needs to reduce costs and maintain the function of the applications The solutions architect uses Cost Explorer and notices that the cost in the EC2-Other category is consistently high A further review shows that NatGateway-Bytes charges are increasing the cost in the EC2-Other category.
What should the solutions architect do to meet these requirements?

A. Enable VPC Flow Log
B. Use Amazon Athena to analyze the logs for traffic that can be remove
C. Ensure that security groups are Mocking traffic that is responsible for high costs.
D. Add an interface VPC endpoint for Kinesis Data Streams to the VP
E. Ensure that applications have the correct IAM permissions to use the interface VPC endpoint.
F. Enable VPC Flow Logs and Amazon Detective Review Detective findings for traffic that is not related to Kinesis Data Streams Configure security groups to block that traffic
G. Add an interface VPC endpoint for Kinesis Data Streams to the VP
H. Ensure that the VPC endpoint policy allows traffic from the applications.

Correct Answer:D
https://docs.aws.amazon.com/vpc/latest/privatelink/vpc-endpoints-access.html
https://aws.amazon.com/premiumsupport/knowledge-center/vpc-reduce-nat-gateway-transfer-costs/
VPC endpoint policies enable you to control access by either attaching a policy to a VPC endpoint or by using additional fields in a policy that is attached to an IAM user, group, or role to restrict access to only occur via the specified VPC endpoint

Question 60

- (Exam Topic 1)
A solutions architect is building a web application that uses an Amazon RDS for PostgreSQL DB instance The DB instance is expected to receive many more reads than writes The solutions architect needs to ensure that the large amount of read traffic can be accommodated and that the DB instance is highly available. Which steps should the solutions architect take to meet these requirements? (Select THREE.)

A. Create multiple read replicas and put them into an Auto Scaling group
B. Create multiple read replicas in different Availability Zones.
C. Create an Amazon Route 53 hosted zone and a record set for each read replica with a TTL and a weighted routing policy
D. Create an Application Load Balancer (ALBJ and put the read replicas behind the ALB.
E. Configure an Amazon CloudWatch alarm to detect a failed read replica Set the alarm to directly invoke an AWS Lambda function to delete its Route 53 record set.
F. Configure an Amazon Route 53 health check for each read replica using its endpoint

Correct Answer:BCF
https://aws.amazon.com/premiumsupport/knowledge-center/requests-rds-read-replicas/
You can use Amazon Route 53 weighted record sets to distribute requests across your read replicas. Within a Route 53 hosted zone, create individual record sets for each DNS endpoint associated with your read replicas and give them the same weight. Then, direct requests to the endpoint of the record set. You can incorporate Route 53 health checks to be sure that Route 53 directs traffic away from unavailable read replicas
