FCP_WCS_AD-7.4 Exam - Question 6

A. The load balancer is configured to load balance traffic among multiple availability zones. The exhibit shows that the ELB spans multiple availability zones, including us-east-2a, us-east-2b, and us-east-2c, indicating that it is set up for cross-AZ load balancing. C. You can use the DNS name to reach the targets behind the ELB. The DNS name (LabELB-716e15332f6401f8.elb.us-east-2.amazonaws.com) provided in the exhibit is used to access the load balancer, which distributes the traffic to the targets behind it. The other options are incorrect: B: The Amazon Resource Name (ARN) identifies the load balancer resource but is not used to access the ELB or its targets. D: The ELB is Internet-facing, as indicated in the exhibit, not configured for internal VPC traffic.

A Page 144 & 145 The main types of load balancers covered in this lesson are ELB and the GWI_B. The ELB encompasses the NLB, the ALB, and the CLB. NLB can handle the varying load of your traffic in a single AZ or across multiple AZs. C. page 45 Amazon Route 53: A scalable and highly available domain name system (DNS) web service, designed to route incoming internet traffic to resources such as web servers, load balancers, and other AWS services.

not D: scheme = internet facing not B: not used to reach load balancers

Explanation: A (The load balancer is configured to load balance traffic among multiple availability zones): The provided ELB configuration shows multiple subnets deployed in different availability zones. ELBs are designed to distribute traffic across multiple AZs to ensure high availability and fault tolerance. This statement is correct. C (You can use the DNS name to reach the targets behind the ELB): AWS ELBs provide a DNS name that clients can use to access your applications. Traffic sent to this DNS name is routed to one of the underlying targets (such as EC2 instances) registered with the load balancer. This statement is also correct.
