1. Correct Answer D

In TCP/IP, the application layer contains all protocols and methods that fall into the realm of process-to-process communications across an Internet Protocol (IP) network. Application layer methods use the underlying transport layer protocols to establish host-to-host connections.

2. Correct Answer A


3. Correct Answer: A

Standard access lists only filter based on source address so they have to be placed as close to the destination as possible.

4. Correct Answer C

Router#copy flash tftp - Cisco IOS is stored in Flash memory on their devices.

5. Correct Answer B

It is rejected because all ACL's by default have an explicit "Deny All" statement at the end, that drops any packet that does not match the list.  This is usually bypassed by adding the "allow any any" statement at the end of the list.
