d. D. Network adds, moves, and changes are achieved with ease by just configuring a port into the
appropriate VLAN

Answer 1

36. c. NVRAM should be erased and the router restarted.
- The startup-config is stored in NVRAM; erase it before loading a new config.

37. c. Fas 0/2
- In the CDP output from SW-3, the Port ID column shows the remote (SW-2) interface as Fa0/2.

38. c. The configuration register setting is incorrect.
- A common cause is the config register set to 0x2142 so the router ignores startup-config on boot. (NVRAM corruption is possible but less common.)

39. d. Ctrl+Shift+6, then X
- Use the Ctrl+Shift+6 (often shown as Ctrl+^), then x to suspend a Telnet session and return to the session prompt.

40. a, b, d. show interfaces; show ip route; ping
- These are useful for diagnosing LAN connectivity on a switch (interface status/errors, routing info on multilayer devices, and reachability tests).

41. d. Network adds, moves, and changes are achieved with ease by just configuring a port into the appropriate VLAN.
- VLANs provide logical segmentation that simplifies moves/adds/changes.
