  The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol in the Internet Protocol Suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, principally wired Ethernet. Media Endpoint Discovery is an enhancement of LLDP, known as LLDP-MED, that provides the following facilities:

  Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority and Differentiated services settings) enabling plug and play networking. Device location discovery to allow creation of location databases and, in the case of Voice over Internet Protocol (VoIP), Enhanced 911 services. Extended and automated power management of Power over Ethernet (PoE) end points.

• Question 8:

  When LLDP is enabled, which value is presented by default as the LLDP Chassis ID on both ProVision and Comware switches?

  A. Router ID
  B. System Name
  C. IP address
  D. MAC address
  D. MAC address

  A network administrator is upgrading the operating system on an HP Comware switch. When copying the new image from a TFTP server to flash of the switch, the process fails because there is not enough flash to store the new operating system. The new operating system is 3.2MB in size. The network administrator then executes the commands shown in the exhibit.

  Which action should the network administrator perform to solve this problem?

  A. Reformat flash and execute the TFTP upgrade command.
  B. Execute the clear Flash command and perform the TFTP upgrade again.
  C. Execute the reset recycle-bin command and perform the TFTP upgrade again.
  D. Execute the delete eld.app command and execute the TFTP upgrade command.
  C. Execute the reset recycle-bin command and perform the TFTP upgrade again.
