easy📝 Conceptual Q1 of 15
AWS - Elastic Load Balancing
What type of traffic does an AWS Network Load Balancer (NLB) primarily handle?
ATCP and UDP traffic at the connection level
BHTTP and HTTPS traffic at the application level
COnly HTTP traffic
DOnly HTTPS traffic
Step-by-Step Solution
Solution:
  1. Step 1: Understand NLB traffic handling

    A Network Load Balancer operates at the transport layer (Layer 4), which means it handles TCP and UDP traffic.
  2. Step 2: Differentiate from other load balancers

    Unlike Application Load Balancers that handle HTTP/HTTPS at Layer 7, NLB focuses on connection-level traffic like TCP and UDP.
  3. Final Answer:

    TCP and UDP traffic at the connection level -> Option A
  4. Quick Check:

    Traffic type = TCP/UDP [OK]
Quick Trick: NLB works at Layer 4 for TCP/UDP, not HTTP/HTTPS [OK]
Common Mistakes:
  • Confusing NLB with Application Load Balancer
  • Thinking NLB handles only HTTP
  • Assuming NLB works at Layer 7
