Which of the following are functionalities provided by AWS Identity and Access Management (IAM)? (Choose two.)

A

Define granular permissions for AWS resources and API actions.

B

Continuously monitor network traffic for intrusions.

C

Enforce the use of a second authentication factor during login.

D

Mitigate distributed denial-of-service (DDoS) attacks.

E

Grant administrative access to on-premises servers.

Explanation

A and C are correct because:
- A: IAM enables granular permissions via policies to control access to AWS resources and API actions.

Other options are incorrect because:

Key Points:
- IAM focuses on authentication, authorization, and access policies.
- MFA is a core IAM feature for securing accounts.
- AWS Shield, WAF, and GuardDuty handle network/DDoS security.
