| Question ID 14409 | Refer to the exhibit.
If host A sends an IP packet to host B, what will the source physical address be in the
frame when it reaches host B?
|
| Option A | 10.168.10.99
|
| Option B | 10.168.11.88
|
| Option C | A1:A1:A1:A1:A1:A1

| Option E | C3:C3:C3:C3:C3:C3
|
| Option F | D4:D4:D4:D4:D4:D4
|
| Correct Answer | E |
Explanation Explanation: When packets transfer from one host to another across a routed segment, the source IP address always remains the same source IP address, and the source physical (MAC) address will be the existing routers interface address. Similarly, the destination IP address always remains the same and the destination physical (MAC) address is the destination routers interface address.
| Question ID 14410 | On a Cisco switch, which protocol determines if an attached VoIP phone is from Cisco or
from another vendor?
|
| Option A | RTP
|
| Option B | TCP
|
| Option C | CDP
|
| Option D | UDP
|
| Correct Answer | C |
Explanation Explanation: The Cisco Unified IP Phone uses CDP to communicate information such as auxiliary VLAN ID, per port power management details, and Quality of Service (QoS) configuration information with the Cisco Catalyst switch. Cisco Discovery Protocol (CDP) is a proprietary protocol designed by Cisco to help administrators collect information about both locally attached and remote devices. By using CDP, you can gather hardware and protocol information about neighbor devices, which is useful info for troubleshooting the network. CDP messages are generated every 60 seconds as multicast messages on each of its active interfaces. The information shared in a CDP packet about a Cisco device includes the following: Name of the device configured with the hostname command IOS software version Hardware capabilities, such as routing, switching, and/or bridging Hardware platform, such as 2600, 2950, or 1900 The layer-3 address(es) of the device The interface the CDP update was generated on Reference: http://computernetworkingnotes.com/cisco-devices-administration-and- configuration/cisco-discoveryprotocol.html
