A storage network engineer is implementing a port channel for multiple FCIP interfaces with write acceleration in a client's storage network. Which channel mode must be used?

Question

Options

• Aon
• Bpassive
• Cactive
• Dforce

• A
  5% (1)
• B
  9% (2)
• C
  82% (18)
• D
  5% (1)

Explanation

Active mode (C) is required for FCIP port channels with write acceleration because this feature depends on dynamic capability negotiation between FCIP peers - the two endpoints must actively exchange and agree on write acceleration parameters before the channel is established.

Why the others are wrong:

• A (on): Static mode - forces the port channel up without any protocol negotiation, so write acceleration capabilities can never be exchanged or agreed upon.
• B (passive): Waits for the remote side to initiate negotiation; if both ends are passive (or the remote isn't actively offering), the required capability exchange stalls, blocking write acceleration.
• D (force): Bypasses normal negotiation entirely to bring the channel up regardless of compatibility, which skips the handshake that write acceleration depends on.

Memory tip: Match the feature to the mode - write acceleration is an active optimization, so it demands active negotiation. If a feature requires two sides to agree on something dynamic, passive or static modes can never guarantee that agreement.
