QUESTION: 1
Refer to the exhibit.
An HP Comware Switch connects to Voice over (VoIP) phones. The phones connect to user’s computes, so each switch port connects a computer and a phone.
These are the specifications:
The VLAN for data traffic is VLAN3
The VLAN for traffic VoIP is VLAN11
The phones support Link Layer Discovery Protocol (LLDP) Media Endpoint Detection (MED).
The network administrator wants to use LLDP-MED to advertise the voice VLAN ID and priority settings to the phones. The phones will then send tagged traffic in that VLAN. The switch should not check the incoming traffic’s MAC address against its voice OID list. The exhibit shows the applicable switch port configuration.
Which additional step must the administrator complete to accomplish this?
A. Enable voice VLAN 11 (voice vlan 11 enable)
B. Change the port to trunk mode (port link-type trunk)
C. Enable LLDP compatibility with Cisco Discovery Protocol (CDP) (lldp compliance admin- status cdp txrx)
D. Enable the port to advertise voice VLAN 11 with LLDP (lldp voice-vlan 11)
Answer: D
QUESTION: 2
A network administrator wants to configure Open Shortest Path (OSPF) MD5 authentication on VLAN 100 on an HP ProVision switch. The administrator has created a global MD5 key chain with an ID and key string that matches the neighbor’s. which additional step must the administrator complete to accomplish this?
A. Set OSPF authentication to MD5 mode in the OSPF area settings
B. Activate MD5 key rotation globally
C. Enable MD5 key rotation globally
D. Assign this MD5 key to OSPF VLAN 100

QUESTION: 3
A network administrator is configuring several HP Comware switches as an HP Intelligent Resilient Framework (IRF) virtual device. According to best practices at, which point during the IRF configuration process should the administrator activate the IRF ports?
A. After enabling the physical interfaces that are assigned to IRF ports and saving the settings
B. After configuring IRF ports but before assigning physical interfaces to them
C. After enabling the physical interfaces that are assigned to IRF ports but before saving the settings
D. Before configuring IRF ports or assigning physical interfaces to them
Answer: A
Explanation:
Use the irf-port-configuration active command to activate configurations on all IRF ports on the device.
When you physically connect members of an IRF virtual device and bind physical IRF port(s) to an IRF port whose link state is DIS or DOWN, which you can display with the display irf topology command, execution of this command is required to establish the IRF virtual device.
Note that activating IRF port configurations may cause merge of IRF virtual devices and automatic device reboot. Therefore, to avoid configuration loss you are recommended to set the member ID for the device in the following way:
1) Plan the network and member IDs in advance. Determine the number of IRF ports to be created, and which physical IRF ports is used for IRF virtual device establishment.
2) Change member IDs. (Member ID change takes effective after device reboot, so change member IDs before executing the irf-port-configuration active command.)
3) Connect SFP+ cables or fibers and make sure that the physical IRF ports are well connected.
4) Create IRF ports.
5) Bind physical IRF ports to IRF ports.
6) Save the current configurations to the configuration file to be used at the next startup.
7) Activate configurations on all IRF ports.
When the system starts up, if you bind a physical IRF port to an IRF port through the configuration file, or add a new physical port, configurations on IRF ports are automatically activated without the need to execute this command again.
QUESTION: 4
A company needs a simple authenticate solution for guests. The HP Comware access layer switches will implement portal authentication (or Web-Auth). The network administrator wants the switch to host the login web page on an IP address that not used for any other purpose.
What should the administrator do to accomplish this goal?
A. Set the IP address when defining the local portal server, and create a loopback interface for the address
B. Create RADIUS scheme that specifies this IP address for the authentication server. Select this scheme for portal authentication in the default domain
C. Create a layer 3 interface for the guest VLAN and assign the desired IP address. Activate local portal authentication on this interface.
D. Set the IP address when defining the local portal server, and the switch automatically begins using that address.

QUESTION: 5
For which use case is a basic or standard access control list (ACL) appropriate?
A. Controlling which devices can access other devices based on the MAC addresses
B. Controlling which devices can access other devices based on the IP protocol number
C. Controlling which devices can access other devices based on the IP addresses
D. Controlling which devices can access other devices based on the source VLAN tag
Answer: C
