Load Balancers Quiz

Question 1 of 5
What is the primary technical trade-off between Layer 4 (L4) and Layer 7 (L7) load balancing in high-throughput architectures?
L4 load balancing requires TLS certificates to route requests, causing higher memory overhead, whereas L7 operates entirely in user-space with zero copy buffers.
L4 operates at the transport layer, routing raw TCP streams with minimal CPU overhead, while L7 decrypts SSL/TLS and inspects HTTP headers/cookies, requiring significantly more CPU resource per request.
L4 is limited to handling UDP traffic and cannot maintain session state, while L7 supports TCP state tracking and Anycast IP routing.
L4 only supports static routing protocols like Weighted Round Robin, whereas L7 allows dynamic routing using client IP hashing.
