A company needs to deploy a multi-region, low-latency read workload
for their globally distributed application using AWS. Which AWS service
and architecture pattern is most appropriate for this requirement?
A. Use AWS Global Accelerator with S3 replication
B. Use Amazon DynamoDB global tables
C. Use RDS Multi-AZ deployment in multiple regions
D. Use Amazon ElastiCache replication across regions
Answer: B
Rationale: DynamoDB global tables provide multi-region, fully replicated,
low-latency reads and writes, which suits the global low-latency read
workload scenario better than RDS multi-AZ (which is regional) or Global
Accelerator (which improves network performance but does not solve
data consistency).
When architecting serverless microservices using AWS Lambda, which of
the following is NOT a recommended best practice?
A. Use environment variables for configuration
B. Package all dependencies within the Lambda function zip
C. Use Lambda layers for shared code or libraries
D. Store session state within Lambda temporary disk (/tmp)
Answer: D
Rationale: Lambda's /tmp storage is ephemeral and limited (512 MB); it
should not be relied on for session state as it can be lost or inconsistent
across invocations.
Which AWS service can you use to implement a decoupled event-driven
architecture with guaranteed message durability and ordering?
2
, A. Amazon SQS standard queues
B. Amazon SQS FIFO queues
C. Amazon SNS topics
D. AWS Step Functions
Answer: B
Rationale: SQS FIFO queues provide message durability, exactly-once
processing, and guaranteed ordering, essential for event-driven
architectures requiring ordering guarantees.
What is the primary benefit of using AWS Transit Gateway in a large
multi-VPC environment?
A. Simplifies VPC peering by providing a centralized hub
B. Reduces NAT Gateway costs
C. Enables IPv6 connectivity between VPCs
D. Acts as a firewall to block traffic between VPCs
Answer: A
Rationale: Transit Gateway acts as a centralized hub to connect multiple
VPCs and on-premises networks, simplifying management and reducing
complexity compared to mesh VPC peering.
If you have an EC2 instance that requires consistent low network latency
and high throughput to accessing an EBS volume, which EBS volume type
should you choose?
A. General Purpose SSD (gp3)
B. Magnetic (standard)
C. Provisioned IOPS SSD (io2)
D. Cold HDD (sc1)
Answer: C
Rationale: Provisioned IOPS SSD (io2) volumes are designed for critical
