When examining SMB connections which are SteelHead optimized, you notice that for each IP client and server pair, there are often two connections created – one on destination port 139 and one on destination port
445. What is the reason for this?

1. A. This is because SMB2 and CIFS optimization are both enabled on the SteelHeads.
2. B. The server must be ignoring or resetting connections on port 139, so the client tries again on port 445.
3. C. The server must be ignoring or resetting connections on port 445, so the client again on port 139.
4. D. Clients often try to connect on port 139 and 445 simultaneously for compatibility reason
