Options- A. Layer 2
- B. Layer 3
- C. Layer 4
- D. Lawer 7
- Correct Answer
- Layer 4
ExplanationA reliable Transport layer connection uses acknowledgments to make sure all data is transmitted and received reliably. A reliable connection is defined by a virtual circuit that uses acknowledgments, sequencing, and flow control, which are characteristics of the transport layer.

Correct Answer: 10000 through 10255255255
Correct Answer: 19216800 through 192168255255
Correct Answer: Transmission of subnet mask information
Explanation:
To use VLSM, the routing protocols in use possess the capability to transmit subnet mask information.
Correct Answer: banner motd
Explanation:
The typical banner is a message of the day (MOTD) and is set by using the global configuration mode command banner motd.
Correct Answer: Physical layer
Explanation:
If you see that a serial interface and the protocol are both down, then you have a physical layer problem. If you see serial 1 is up, line protocol is down, then you are not receiving (Data Link) Keepalives from the remote end.
Correct Answer: copy tftp flash
Explanation:
The command copy tftp flash will allow you to copy a new IOS into flash memory on your router.
