1.Which of the following features ensures even distribution of traffic to Amazon EC2 instances in multiple Availability Zones registered with a load balancer?

A.Elastic Load Balancing request routing

B.An Amazon Route 53 weighted routing policy

C.Elastic Load Balancing cross-zone load balancing

D.An Amazon Route 53 latency routing policy

Answer:C

Elastic Load Balancing cross-zone load balancing

Explanation:

Cross-zone load balancing ensures that traffic is evenly distributed across all registered Amazon EC2 instances, regardless of the Availability Zone (AZ) they are in.
When enabled, each load balancer node distributes traffic across all registered instances in all AZs, helping to maintain even traffic distribution.
It improves load balancing efficiency, especially when instance counts vary between zones.

3.Does Dynamic DB support in-place atomic updates?

A.It is not defined

B.No

C.Yes

D.It does support in-place non-atomic updates

Answer:C

Yes

Explanation:

Amazon DynamoDB supports in-place atomic updates through the use of the UpdateItem API.
Atomic updates allow you to modify attributes in a single, all-or-nothing operation, ensuring that the update is applied only if specific conditions are met.
This is useful for incrementing counters or making conditional updates without conflicts.

5.Are you able to integrate a multi-factor token service with the AWS Platform?

A.No, you cannot integrate multi-factor token devices with the AWS platform.

B.Yes, you can integrate private multi-factor token devices to authenticate users to the AWS platform.

C.Yes, using the AWS multi-factor token devices to authenticate users on the AWS platform.

Answer:C

Yes, using the AWS multi-factor token devices to authenticate users on the AWS platform.

Explanation:

AWS Multi-Factor Authentication (MFA) enhances security by requiring users to provide an additional authentication factor beyond just a username and password.
AWS supports the use of:
- Virtual MFA devices (such as Google Authenticator or Authy).
- Hardware MFA devices (such as Gemalto tokens or YubiKey).
MFA can be enabled for IAM users and the root account to protect access to AWS resources.
