Explanation
A question asking to choose two correct pairings of an application integration or monitoring service with its role.
- 1「application integration or monitoring service with its role」Correctly map the roles of SQS/SNS/CloudWatch
BIncorrect
Amazon SNS — a persistent block storage that attaches to EC2.
This description is about storage; the persistent block storage that attaches to EC2 is Amazon EBS.
Amazon SNS is a Pub/Sub (publish/subscribe) messaging service. When a publisher sends a message once to a topic, it is delivered simultaneously (fan-out) to multiple subscribers (such as Lambda, SQS, email, and HTTP) that subscribe to that topic. It is used to broadcast one event to many systems. The storage description is wrong, so it is incorrect.
CIncorrect
Amazon CloudWatch — an audit log that records who performed which API operation.
Recording who performed which API operation is AWS CloudTrail.
CloudWatch is a metrics and log monitoring service, so the description is wrong and incorrect.
DCorrect
Amazon CloudWatch — collects and monitors metrics and raises an alarm when a threshold is exceeded.
This is correct. Amazon CloudWatch collects and monitors metrics and logs, and when a threshold is exceeded it raises an alarm to send a notification or run an action.
EIncorrect
Amazon SQS — a DNS that translates domain names into IP addresses.
The DNS that translates domain names into IP addresses is Amazon Route 53.
SQS is a message queue, so the description is wrong and incorrect.
Key Takeaway
Pairings: SQS = queue (in-order processing) / SNS = Pub/Sub (broadcast) / CloudWatch = metric monitoring and alarms / EventBridge = event routing. Beware of confusing CloudWatch (monitoring) with CloudTrail (auditing).
