Refer to the exhibit. A network administrator attempts to improve multicast traffic flow and performs some packet captures for validation. What can the network administrator conclude from the results?

Question

Exhibit

Options

• AThe data rate increased from 6 Mbps to 300 Mbps because Broadcast Multicast Optimization
• BThe type field remains consistent because Dynamic Multicast Optimization (DMO) was
• CThe data rate increased from 6 Mbps to 300 Mbps because Dynamic Multicast Optimization
• DThe capture taken after optimization does not show a packet length because Multicast

• A
  6% (2)
• B
  3% (1)
• C
  79% (26)
• D
  12% (4)

Explanation

Dynamic Multicast Optimization (DMO) converts multicast frames into individual unicast frames for each client. Since unicast frames can use the full negotiated data rate between the AP and client (up to 300 Mbps), rather than the conservative base rate required for multicast transmissions (6 Mbps), the packet capture after optimization correctly shows the dramatic data rate increase - confirming option C.

Why the distractors fail:

• A uses the fictional term "Broadcast Multicast Optimization" - no such standard feature exists; the correct term is DMO.
• B claims the type field stays consistent, but DMO fundamentally changes the frame type from multicast to unicast, so the type field would differ between captures.
• D is incomplete and references the wrong feature name, making it incoherent as a conclusion.

Memory tip: Think of DMO as "Multicast Disguised as Unicast" - by disguising multicast as individual unicast transmissions, the AP unlocks the fast lane (300 Mbps) instead of staying in the slow multicast lane (6 Mbps).
