1. Understanding Link Aggregation in NSX

IP Hash and LACP (Link Aggregation Control Protocol) are methods for link aggregation used in NSX-T networking.

Both techniques allow multiple physical links to be combined into a logical interface for higher bandwidth and redundancy.

2. Why "IP Hash Uses a Hash Function, LACP Uses a Control Protocol" is Correct (C)

IP Hash:

Uses a hashing functionto distribute traffic based onsource and destination IP addresses.

It does not negotiate link aggregation dynamically.

LACP:

Uses a control protocolto dynamically negotiate and maintain aggregated links.

Automatically detects and manages failures in aggregated links.

3. Why Other Options are Incorrect

(A - IP Hash Uses Control Protocol):

IP Hash does not use a control protocol; it only applies a hash function.

(B - LACP Uses Hashing Instead of Control Protocol):

LACP does not use a hash function for traffic distribution; it uses a negotiation protocol.

(D - LACP Hashes MAC Instead of IP):

LACP does not perform hashing; it manages link aggregation dynamically.

4. NSX Best Practices for Link Aggregation

LACP is recommended for environments where dynamic link negotiation is required.

IP Hash is used in environments where static load balancing is preferred.

Ensure the correct uplink profile is assigned to NSX Transport Nodes for link aggregation.
