b) They provide better security than IAM roles
c) They reduce cloud storage costs
d) They allow unauthorized access by default
Answer: a) They increase the risk of credential leaks
Explanation: Long-term access keys can be stolen or misused, posing security risks.
187. What IAM best practice improves security when managing permissions?
a) Implementing the principle of least privilege
b) Assigning full permissions to all IAM users
c) Using a single IAM user for all cloud resources
d) Disabling IAM policies
Answer: a) Implementing the principle of least privilege
Explanation: Least privilege access ensures users receive only the permissions required for their tasks.
188. How can organizations detect unusual IAM activity?
a) Enable CloudTrail logging and monitoring
b) Disable IAM policy versioning
c) Assign IAM root access to all users
d) Use a single IAM user for all cloud applications
Answer: a) Enable CloudTrail logging and monitoring
Explanation: CloudTrail logs IAM activities, helping detect unusual behavior.
189. What IAM feature helps enforce a “Zero Trust” security model?
a) Conditional access policies with strict rules
b) Using a shared IAM administrator account
c) Assigning full IAM permissions to all users
d) Using default IAM settings
Answer: a) Conditional access policies with strict rules
Explanation: Conditional access policies enforce strict, context-based access control for a Zero Trust model.
190. Why should IAM groups be used instead of assigning permissions to individual users?
a) IAM groups simplify permission management
b) IAM groups allow users to bypass IAM policies
c) IAM groups provide more storage for IAM credentials
d) IAM groups eliminate the need for IAM roles
Answer: a) IAM groups simplify permission management
Explanation: IAM groups enable efficient permission assignment to multiple users.
191. What IAM feature allows organizations to block unauthorized API requests from certain locations?
a) IAM policy conditions with aws:SourceIp
b) IAM policy versioning
c) IAM access key rotation
d) IAM password expiration policies
Answer: a) IAM policy conditions with aws:SourceIp
Explanation: IAM policies with aws:SourceIp restrict API access based on the source IP address.
192. What should be done when an IAM user’s access is no longer needed?
a) Disable or delete the IAM user immediately
b) Assign the IAM user a different role
c) Store the IAM user’s credentials in a backup file
d) Keep the IAM user active indefinitely
Answer: a) Disable or delete the IAM user immediately
Explanation: Removing unused IAM accounts minimizes security risks.
193. How can organizations prevent unauthorized changes to IAM policies?
a) Use Service Control Policies (SCPs) to restrict modifications
b) Assign all users administrative access
c) Disable IAM role-based access control
d) Use hardcoded credentials for authentication
Answer: a) Use Service Control Policies (SCPs) to restrict modifications
Explanation: SCPs enforce IAM policy restrictions across an organization.
194. What is a risk of using overly permissive IAM policies?
a) Unauthorized access to cloud resources
b) Reduced cloud computing performance
c) IAM policies not functioning properly
d) Increased IAM storage costs
Answer: a) Unauthorized access to cloud resources
Explanation: Overly permissive IAM policies can lead to data breaches and security threats.
195. What IAM security measure prevents unauthorized role assumption?
a) IAM trust policies with strict conditions
b) Assigning IAM roles to all users
c) Enabling IAM wildcard permissions
d) Allowing root user access to modify roles
Answer: a) IAM trust policies with strict conditions
Explanation: IAM trust policies define who can assume roles, preventing unauthorized access.
196. What is the main advantage of using IAM federated authentication?
a) Users can authenticate using external identity providers
b) Users are automatically granted full access
c) IAM passwords are stored in plaintext
d) IAM roles are no longer needed
Answer: a) Users can authenticate using external identity providers
Explanation: Federated authentication enables secure access via third-party identity providers.
197. What is the function of an IAM access advisor?
a) It identifies unused permissions assigned to IAM users and roles
b) It automatically grants full IAM permissions
c) It disables IAM policies for inactive users
d) It stores IAM credentials securely
Answer: a) It identifies unused permissions assigned to IAM users and roles
Explanation: IAM Access Advisor helps optimize permissions by detecting unused privileges.
198. Why should IAM users avoid using the root account for daily tasks?
a) The root account has unrestricted access and poses a security risk
b) The root account has limited permissions
c) The root account cannot create IAM users
d) The root account automatically resets passwords
Answer: a) The root account has unrestricted access and poses a security risk
Explanation: The root account should only be used for critical administrative tasks.
199. What is the best IAM practice for securing API credentials?
a) Store API credentials in a secrets management service
b) Hardcode credentials in the application code
c) Use a single access key for all API calls
d) Disable authentication for APIs
Answer: a) Store API credentials in a secrets management service
Explanation: Secrets management tools securely store and manage API credentials.
200. What IAM feature helps organizations enforce security best practices?
a) IAM security audits and compliance monitoring
b) Assigning root access to all IAM users
c) Using shared IAM credentials
d) Disabling IAM logging
Answer: a) IAM security audits and compliance monitoring
Explanation: Regular IAM audits ensure compliance with security policies.
