Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 5

What is the difference between PIM sparse mode and PIM dense mode?

Answer options

• A. Sparse mode supports only one switch. Dense mode supports multiswitch networks.
• B. Sparse mode floods. Dense mode uses distribution trees.
• C. Sparse mode uses distribution trees. Dense mode floods.
• D. Sparse mode supports multiswitch networks. Dense mode supports only one switch.

Correct answer: C

Explanation

The correct answer is C because PIM sparse mode uses distribution trees to efficiently manage multicast traffic by only sending data to nodes that need it, whereas PIM dense mode floods the network with traffic, assuming all nodes are interested. The other options incorrectly describe the functionalities of sparse and dense modes.
