2. Answer C is correct. You should use a special RJ-45-to-RJ-45 rollover cable to connect a data terminal or console to the RJ-45 console port of a switch. An adapter may be needed to connect to the appropriate port on the data terminal or console. Be certain not to connect a live Ethernet connection, ISDN line, or analog telephone line to an RJ-45 console port on a switch; doing so may damage the switch. You should use an unshielded twisted pair (UTP) crossover cable if you want to connect a switch to a repeater or to another switch. You should use a standard, straight-through UTP cable to connect a router or a client workstation to a switch.

3. Answer B is correct. CAT 5 UTP crossover cable can be used to connect two switches.

Choices A, C, and D are incorrect. A management cable, a RJ-45 to DB-9 terminal cable, is used to connect a PC to a switch (or router). A RJ-45-to-RJ-45 rollover cable is used to connect the console port of the switch to a console PC or terminal. A straight cable can be used to connect a switch to a router or a workstation.

4. Answer A is correct. Before you enable CGMP on a switch, you must disable IGMP snooping if it is enabled. If you try to enable CGMP without first disabling IGMP snooping, an error message is generated.

5. Answer B is correct. Cat 5 UTP crossover cabling can be used to connect two switches.

Choice A is incorrect. A management cable, a RJ-45 to DB-9 terminal cable, is used to connect a PC to a switch (or router).

Choice C is incorrect. A RJ-45-to-RJ-45 rollover cable is used to connect the console port of the switch to a console PC or terminal.

Choice D is incorrect. A straight cable can be used to connect a switch to a router or a workstation.

6. Answer D is correct. The traffic has to be routed between the VLANs. A routing mechanism has to be provided for interVLAN communication.

Choices A and B are incorrect. Either IEEE 802.1Q or ISL trunking protocol can be used.

Choice C is also incorrect. Access switch has no use for interVLAN routing.

7. Answer C is correct. If a device is correctly connected to a port, and the device is powered on, the port light emitting diode (LED) will come on and stay on.

Choice A is incorrect as it is not used to see the loop.

Choice B is incorrect as it does not identify RTS signals.

Choice D is also incorrect. If lights comes on and goes off, then that means the device is not correctly connected.

8. Answer C is correct. The show standby command will display the virtual IP address, the virtual MAC address, and the IP address of the active and standby routers.

Choices A, B, and D are incorrect. There are no such commands.

9. Answer A is correct. Trunking is a way to carry traffic from several VLANs over a point-to-point link between the two devices. Two ways in which Ethernet trunking can be implemented are:

• ISL (Cisco proprietary protocol)
• 802.1Q (Institute of Electrical and Electronics Engineers (IEEE) standard)

The native VLAN is the VLAN to which the port will belong if that link becomes non-trunk.

10. Answer B is correct. In order for CGMP to operate correctly on a switch, the switch must have a network connection to a router running CGMP. A CGMP-capable IP multicast router detects all ICMP packets and informs the switch when specific hosts join or leave IP multicast groups.
