1. Correct Answer C

disable the current interface

2. Correct Answer B

Routed protocols
ROUTED PROTOCOLS are nothing more than data being transported across the networks.
Eg IP, IPV6 and IPX

ROUTING PROTOCOLS are the software that allow routers to dynamically advertise and learn routes, determine which routes are available and which are the most efficient routes to a destination.

3. Correct Answer A

DTE devices (Data Terminal Equipment) which basically means they receive or slave off the clock source provided by the carrier Circuit (DCE). Cisco Interfaces can be configured to DCE mode (they supply clock) by adding the Clock rate command.

4. Correct Answer B

Copy the running configuration to NVRAM

5. Correct Answer A

Internally multicast is treated the same as a broadcast. So the Switch will send it to all ports except from which it was recieved. Same way it will treat a broadcast.

6.  Correct Answer: D

IGRP sends its routing table to its neighbors every 90 seconds. IGRP uses an invalid timer to mark a route as invalid after 270 seconds (three times the update timer). IGRP uses a flush timer to remove a route from the routing table (default flush timer is 630 seconds, seven times the update period).
