A network architect is designing a new network and must ensure that devices from different vendors can interoperate. The architect is considering whether to use the OSI model or the TCP/IP model as the design reference. Which consideration is most important for ensuring vendor interoperability?

The choice of model does not affect interoperability because all networking devices use the same protocols.

The OSI model is outdated, so using it would hinder interoperability with modern devices.

Using the TCP/IP model ensures that all devices use the same protocols, which is sufficient for interoperability.

Using the OSI model as a reference ensures that each layer's functions are clearly defined, promoting standard-based implementation.

A network analyst is troubleshooting a performance issue. The analyst captures packets and sees that the TCP window size is consistently small, and the receiver is sending frequent ACK packets. The analyst suspects the issue is at the transport layer. Which action would best confirm this suspicion?

Check the Ethernet frame size for jumbo frames.

Check the IP header for TTL values.

Check for TCP retransmissions and duplicate ACKs in the capture.

Check the HTTP response headers for server delays.
