Q1. An orgAMzation has 10000 employees. The orgAMzation wants to give restricted AWS access to each employee. How can the orgAMzation achieve this?

A. Create an IAM user for each employee and make them a part of the group

B. It is not recommended to support 10000 users with IAM

C. Use STS and create the users’ run time

D. Use Identity federation with SSO

Answer: D

Explanation:

Identity federation enables users from an existing directory to access resources within your AWS account,

making it easier to manage your users by maintaining their identities in a single place. In this case, the federated user is the only solution since AWS does not allow creating more than 5000 IAM users. Reference: http://docs.aws.amazon.com/IAM/latest/UserGuide/LimitationsOnEntities.html

Q2. A user is creating a new EBS volume from an existing snapshot. The snapshot size shows 10 GB. Can the user create a volume of 30 GB from that snapshot?

A. Provided the original volume has set the change size attribute to true

B. Yes

C. Provided the snapshot has the modify size attribute set as true

D. No

Answer: B

Explanation:

A user can always create a new EBS volume of a higher size than the original snapshot size. The user cannot create a volume of a lower size. When the new volume is created the size in the instance will be shown as the original size. The user needs to change the size of the device with resize2fs or other OS specific commands.

Q3. A user has launched one EC2 instance in the US West region. The user wants to access the RDS instance launched in the US East region from that EC2 instance. How can the user configure the access for that EC2 instance?

A. It is not possible to access RDS of the US East region from the US West region

B. Open the security group of the US West region in the RDS security group’s ingress rule

C. Configure the IP range of the US West region instance as the ingress security rule of RDS

D. Create an IAM role which has access to RDS and launch an instance in the US West region with it

Answer: C

The user cannot authorize an Amazon EC2 security group if it is in a different AWS Region than the RDS DB instance. The user can authorize an IP range or specify an Amazon EC2 security group in the same region that refers to an IP address in another region.

Reference: http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithSecurityGroups.html

Q4. A user has attached one RDS security group with 5 RDS instances. The user has changed the ingress rule for the security group. What will be the initial status of the ingress rule?

A. Approving

B. Implementing

C. Authorizing

D. It is not possible to assign a single group to multiple DB instances

Answer: C

Explanation:

When the user makes any changes to the RDS security group the rule status will be authorizing for some time until the changes are applied to all instances that the group is connected with. Once the changes are propagated the rule status will change to authorized.
