Question #6
Refer to the exhibit.

A company wants to implement a portal authentication solution for guests (such a solution is also called Web-Auth). Guest belong to VLAN4, as shown in the exhibit. The intelligent Management Center (IMC) User Access Manager (UAM) will provide authentication and the Web Portal.
Where should the network administrator enable portal authentication?
  1. A
    On the VLAN 4 interface on the core IRF virtual switch
  2. B
    On the ports with membership for VLAN 4 on the access layer IRF virtual switches
  3. C
    On the ports with membership for VLAN 4 on the core IRF virtual switch
  4. D
    On VLAN 4 on the core IRF virtual switch

Correct Answer:
B
Creating a VLAN Interface for the Web-Auth VLAN
The Wireless Edge Services xl Module requires an IP address on the static VLAN to which the Web-Auth WLAN maps. This VLAN must be accessible to the guests, so it should be the VLAN on the access layer IRF virtual switches.

Question #7
Refer to the exhibit.

Switch 1 and switch 2 run open Shortest Path First (OSPF) on all VLANs. Both switches establish an OSPF adjacency to a router at the main data center. Exhibit shows shoes some virtual Routing Redundancy Protocol (VRRP) and OSPF settings on Switch 1 during normal operation.
How can a network administrator increase the resiliency of this solution?
  1. A
    Implement Bidirectional Forwarding Detection (BFD) on the peer keep alive link between the core switches.
  2. B
    Change the VLAN 10 subnet to a /24 subnet and enable VRRP on it. Place Switch 2’s link to the main data center in this subnet.
  3. C
    Make sure that, in each VRRP instance, each switch has a VRRP preempt delay of several minutes.
  4. D
    Configure Switch 1 as an OSPF graceful restart helper in VLAN 11 and Switch 2 as a helper in VLAN 10

Correct Answer:
D
Today many Internet routers implement a separation of control and forwarding functions. Certain processors are dedicated to control and management tasks such as OSPF routing, while other processors perform the data forwarding tasks. This separation creates the possibility of maintaining a router's data forwarding capability while the router's control software is restarted/reloaded. We call such a possibility "graceful restart" or "non-stop forwarding".

Question #8
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 neighbors. which additional step must the administrator complete to accomplish this?
  1. A
    Set OSPF authentication to MD5 mode in the OSPF area settings
  2. B
    Activate MD5 key rotation globally
  3. C
    Enable MD5 key rotation globally
  4. D
    Assign this MD5 key to OSPF VLAN 100

Correct Answer:
D
Authentication-key: OSPF supports three methods of authentication for each interfacenone, simple password, and MD5. Only one method of authentication can be active on an interface at a time.
The MD5 method of authentication requires you to configure a key ID and an MD5 Key

Question #9
Refer to the exhibit.

A user connects a device to GigabitEthernet 1/0/1 on switch. The device does not have an 802.1X supplicant. One minute passes. How does the switch port handle the client?
  1. A
    It blocks the client
  2. B
    It assigns the client to VLAN2
  3. C
    It assigns the client to VLAN3
  4. D
    It assigns the client to VLAN4

Correct Answer:
D
VLAN4 is configured to be a guest vlan.

Question #10
A company uses 802.1X authentication to force users to connect to the network. The company uses access layer switches to enforce the 802.1X authentication and HP IMC User Access manager (UAM) as the RADIUS server.
The customer requires switches to apply a specific settings to contractor use connections. The network administrator checks the switch documentation and determines that this settings uses a vendor-specific attribute (VSA). The administrator check UAN and verifies that it has this VSA defined on it.
How does administrator configure UAM to apply the correct setting?
  1. A
    Define IP port groups on the access devices that need to receive the settings. Configure the VSA and its settings within these groups
  2. B
    Add the settings to the VSA definition and then activate the VSA globally
  3. C
    Create a scenario with the VSA and its settings: apply this scenario to the access devices that need to receive the settings
  4. D
    Create a proprietary attribute policy with the VSA and its settings; apply this policy in the service policy for the contractor users

Correct Answer:
C
HP IMC User Access Management customizable portal pages for smart devices based on access scenarios provide a unique and personalized client experience.
