• Question 12:

  Which HP device or port type can modify, read, and respond to 802.1Q VLAN tags?

  A. ProVision loopback ports
  B. Comware tagged ports
  C. Comware trunk ports
  D. Provision untagged ports
  C. Comware trunk ports

• Question 13:

  Refer to the exhibit. Exhibit: Network topology

  

  A company has implemented a switched network based on the RSTP spanning tree protocol. Assume the following:

  

  All switches have the same priority

  

  All ports have the same cost

  

  All ports have the same priority

  Based on this information, which answer is correct?

  A. Port 2 on SwitchC is a designated port.
  B. Port 3 on SwitchC is a designated port.
  C. Port 1 on SwitchB is a discarding port.
  D. Port 1 on SwitchD is a root port.
  B. Port 3 on SwitchC is a designated port.

  ---

  MSTP selects the device with the lowest MAC address as the root bridge, so in this case it is SwitchD. The root bridge is the only bridge in the network that does not have a root port. All other bridges receive BPDUs on at least one port.

• Question 14:

  All OSPF routers from adjacencies with other OSPF routers in each broadcast domain.

  What is the correct sequence of states when forming an adjacency with any OSPF router in the broadcast domain?

  Hot Area:

  

  

  ---

  Step 1 Two-way state

  Step 2 Exchange state

  Step 3 Domain Static

• Question 15:

  Refer to the exhibit.

  Exhibit: HP ProVision command output

  

  What does the term "blackhole" mean for the 10.11.30.0/24 route?

  A. The switch will drop all traffic sourced from 10.11.30.0/24 and will send an ICMP message to the source.
  B. The switch will drop all traffic sourced from 10.11.30.0/24 and will not send an ICMP message to the source.
  C. The switch will drop all traffic destined to 10.11.30.0/24 and will not send an ICMP message to the source.
  D. The switch will drop all traffic destined to 10.11.30.0/24 and will send an ICMP message to the source.
  C. The switch will drop all traffic destined to 10.11.30.0/24 and will not send an ICMP message to the source.

• Question 16:

  Which HP ProVision switch command could a network administrator use to upgrade the operating system from an attached USB drive?

  A. Update from usb flash
  B. Copy usb flash
  C. File-management usb
  D. Upgrade usb flash
  B. Copy usb flash

• Question 17:

  Which wireless technology is limited to operate in a frequency range with only three non- overlapping channels?

  A. 802.1a
  B. 802.1x
  C. 802.1ad
  D. 802.11g
  D. 802.11g

  ---

  802.11b (and 802.11g) networks offer 11 channels, but only three channels (1, 6, and 11) do not overlap with each other. In a large-scale building or campus-wide installation, the ability to use only three channels can reduce real-world throughput and make avoiding interference from other 802.11b or 802.11g-based wireless networks difficult.

• Question 18:

  A company has purchased Intelligent Management Center (IMC) and wants to centralize AAA policies for the HP switches on the IMC server. Which protocol should the company use for the interaction between the IMC server and the HP switches?

  A. LACP
  B. LLDP
  C. SNMP
  D. RADIUS
  D. RADIUS

• Question 19:

  Refer to the exhibit.

  Exhibit: Network topology and configuration

  

  Originally, all four switches had the same region configuration. VLAN 14 was added to Switch_D and then mapped to instance 2. How does this affect the MSTP topology?

  A. Load sharing is lost, one of the uplinks is blocked for all traffic on Switch_C and Switch_D
  B. A layer 2 loop exists and will cause sporadic connectivity issues
  C. All connectivity is lost, both uplinks are blocked on Switch_D
  D. Load sharing is lost, one of the uplinks is blocked for all traffic on Switch_D
  C. All connectivity is lost, both uplinks are blocked on Switch_D

• Question 20:

  Refer to the exhibit. Exhibit: Network topology

  

  The server shown in the exhibit is configured for dynamic LACP. There is only one link between Switch 1 and Switch 2. Which HP switching solution should the network administrator implement?

  A. Distributed trunking on Comware Switches or ProVision switches
  B. IRF on Comware switches or Provision switches
  C. IRF on Comware switches or but not on ProVision switches
  D. Distributed trunking on ProVision switches but not on Comware switches
  C. IRF on Comware switches or but not on ProVision switches
