NEW QUESTION 1
A user is configuring the HTTPS protocol on a front end ELB and the SSL protocol for the back-end listener in ELB. What will ELB do?

• A. It will allow you to create the configuration, but the instance will not pass the health check
• B. Receives requests on HTTPS and sends it to the back end instance on SSL
• C. It will not allow you to create this configuration
• D. It will allow you to create the configuration, but ELB will not work as expected

Answer: C

Explanation: If a user is configuring HTTPS on the front end and TCP on the back end, ELB will not allow saving these listeners and will respond with the message.
"Load Balancer protocol is an application layer protocol, but instance protocol is not. Both the Load Balancer protocol and the instance protocol should be at the same layer. Please fix."

• B. lVIuIti AZ instances are not possible with a single ELB
• C. Nlulti AZ instances will provide scalability with ELB
• D. The user can achieve both HA and scalability with ELB

Answer: A

Explanation: If a user is running two instances in separate AZs, it will provide HA with ELB since ELB will automatically stop routing the traffic to unhealthy instances and send it to healthy instances only.

NEW QUESTION 6
An ELB is diverting traffic across 5 instances. One of the instances was unhealthy only for 20 minutes. What will happen after 20 minutes when the instance becomes healthy?

• A. ELB will never divert traffic back to the same instance
• B. ELB will not automatically send traffic to the same instanc
• C. However, the user can configure to start sending traffic to the same instance
• D. ELB starts sending traffic to the instance once it is healthy
• E. ELB terminates the instance once it is unhealth
• F. Thus, the instance cannot be healthy after 10 minutes

Answer: C

Explanation: AWS Elastic Load Balancing continuously checks the health of an instance. If one of the instances is unhealthy it stops sending traffic to it and automatically reroutes the traffic to the remaining running EC2 instances. If the failed EC2 instance is restored, Elastic Load Balancing will again start sending traffic to that instance.

NEW QUESTION 9
A user has launched five instances with ELB. How can the user add the sixth EC2 instance to ELB?

• B. The user must stop the ELB and add the sixth instance.
• C. The user can add the instance and change the ELB config file.
• D. The ELB can only have a maximum of five instance

Answer: A

Explanation: Elastic Load Balancing automatically distributes incoming traffic across multiple EC2 instances. You create a load balancer and register instances with the load balancer in one or more Availability Zones. The load balancer serves as a single point of contact for clients. This enables you to increase the availability of your application. You can add and remove EC2 instances from your load balancer as your needs change, without disrupting the overall flow of information.

NEW QUESTION 19
A user is trying to configure access with S3. Which of the following options is not possible to provide access to the S3 bucket / object?

• A. Define the policy for the IAM user
• B. Define the ACL for the object
• C. Define the policy for the object
• D. Define the policy for the bucket

Answer: C

Explanation: Amazon S3 offers access policy options broadly categorized as resource-based policies and user policies.
Access policies, such as ACL and resource policy can be attached to the bucket. With the object the user can only have ACL and not an object policy. The user can also attach access policies to the IAM users in the account. These are called user policies.
