Question

Options

• AApplication Load Balancer
• BAWS WAF
• CAWS CloudHSM
• DAWS Direct Connect

• A
  86% (57)
• B
  8% (5)
• C
  2% (1)
• D
  5% (3)

Explanation

Application Load Balancer (ALB) is the right choice because it is specifically designed to distribute incoming web traffic across multiple EC2 instances, improving availability and scalability - exactly what an ecommerce website needs to handle varying loads efficiently.

AWS WAF (Web Application Firewall) is a security service that protects against common web exploits like SQL injection and cross-site scripting - it filters traffic but does not distribute it. AWS CloudHSM is a hardware security module used for cryptographic key management and data encryption, which has nothing to do with traffic distribution. AWS Direct Connect provides a dedicated private network connection between an on-premises data center and AWS, not traffic distribution between EC2 instances.

Memory Tip: Think of a "load balancer" like a traffic cop standing at an intersection - it directs cars (requests) evenly to different roads (EC2 instances) to prevent congestion. Whenever you see keywords like "distribute traffic," "balance load," or "multiple EC2 instances," your answer is almost always a Load Balancer.
