• Question 1:

  Table of Acronyms

  

  Refer to the exhibit.

  

  An administrator is setting up MPLS Layer 2 VPN connections between several customer sites:

  Connection 1 = Customer site 1 to customer site 2

  Connection 2 = Customer site 1 to customer site 3 On PE-1, interface GigabitEthernet1/0/1 connects to CE-1 at site 1. Which setup establishes the desired connections?

  A. CE-1 connects to CE-2 in one VLAN, which it assigns to VPN instance 1. It connects to CE-3 in a different VLAN, which it assigns to VPN instance 2. PE-1 instant places G1/0/1 in both VPN instances 1 and 2 and associates each VPN instance with a PW for one of the connections.
  B. CE-1 connects to CE-2 in one VLAN and to CE-3 in a different VLAN. PE-1 has two services instances on G1/D/1. One instance encapsulates one VLAN ID and has PW to PE-2, and the other instance encapsulates the other VLAN and has a PW to PE-3
  C. PE-1 has two policy-based routing (PBR) policies, each of which selects traffic destined to Site 2 or Site 3. The appropriate policy is applied to the PW for each connection
  D. CE-1 implements MPLS. It establishes two PWs with PE-1, one for its connection to CE-2 and one for its connection to CE-3. PE-1 maps the out label for the first PW to the in label for a PW to PE-2. It maps the labels similarly for a PW to PE-3.
  A. CE-1 connects to CE-2 in one VLAN, which it assigns to VPN instance 1. It connects to CE-3 in a different VLAN, which it assigns to VPN instance 2. PE-1 instant places G1/0/1 in both VPN instances 1 and 2 and associates each VPN instance with a PW for one of the connections.

  A. Required
  B. Fixed
  C. Not required
  D. Invisible
  E. Random

• Question 5:

  Table of Acronyms

  

  Refer to the exhibit.

  

  An administrator wants to route all external traffic from VPN instances "TenantA" and "TenantB" to a firewall at 10.0.5.5 instance "SharedServices". In addition to setting up the routes between the instances, what is another requirement for this scenario?

  A. A router must implement Network Address Translation (NAT) to translate overlapping tenant network addresses.
  B. Route leaking must be enabled globally on Router1, as well as on each of the VPN instances.
  C. The RAGG 3 interface must be added to VPN instances "TenantA" and "TenantB".
  D. Route leaking must be enabled globally on Router1.
  C. The RAGG 3 interface must be added to VPN instances "TenantA" and "TenantB".

• Question 6:

  Table of acronyms

  

  Refer to the exhibit.

  

  An administrator is setting up an MPLS and L2VPN virtual circuit (VC) between customer Site 1 and Site 2. The administrator is creating a global cross-connect group, which uses LDP signaling, on PE-1. Which two elements are required to do this?

  A. An AC connection (specifies a service instance on g1/0/1) and a peer (PE-2)
  B. A peer (PE-2) and a VPN instance (associated with g1/0/1)
  C. A peer (PE-2) and a VLAN ID (access VLAN or. g1/0/1)
  D. An AC connection (specifies a service instance on g1/0/1) and a VPN instance (associated with g1/0/1)
  C. A peer (PE-2) and a VLAN ID (access VLAN or. g1/0/1)
  D. An AC connection (specifies a service instance on g1/0/1) and a VPN instance (associated with g1/0/1)

• Question 7:

  An HP Unified Wired-Wireless controller controls an AP. The AP implements centralized forwarding. It supports 802.11n clients that implement Wi-Fi Multimedia (WMM) or 802.11 e. Some of the clients are sending traffic in high priority WMM queues.

  How does the AP help to ensure that this traffic is prioritized in the wired LAN?

  A. It maps 802.11 values from wireless traffic to DiffServ Code Points (DSCP) in packets tunneled to the controller.
  B. It implements 802.11n fair scheduling on the port that connects to the switch.
  C. It maps 802.1p values from wireless traffic to 802.11 e values in packets forwarded into the LAN.
  D. It implements Spectralink and uses Spectralink-to-WMM compliance mode.
  A. It maps 802.11 values from wireless traffic to DiffServ Code Points (DSCP) in packets tunneled to the controller.

• Question 8:

  A company has an HP Unified Wired-Wireless controller that controls HP MultiService Mobility (MSM) APs. The network administrator wants to implement protection against rogue APs in the company's campus environment. Only APs that have approved MAC addresses should be allowed to operate and support clients. Controlled APs should send disassociation frames to prevent clients from connecting to rogue APs.

  The administrator sets up APs to monitor the area and creates a permitted MAC address list with the approved AP MAC addresses. The administrator has not configured any other Intrusion Detection System (IDS) settings. Which additional step must the administrator complete?

  A. Enable a dynamic blacklist.
  B. Configure the permitted vendor and permitted SSID lists.
  C. Enable countermeasures.
  D. Deploy the permitted MAC address list as a static attack list to each controlled AP
  C. Enable countermeasures.

• Question 9:

  A. Channel reuse
  B. Dynamic frequency selection (DFS)
  C. Transmit power control (TPC)
  D. Fair scheduling
  A. Channel reuse

• Question 10:

  An administrator has set up an HP BYOD solution for an HP MSM760 controller and its APs.

  These are the specifications:

  

  Guests should only have to register and log in once After that, the guest device should be automatically logged in.

  

  User Access Manager (UAM) provides the portal in which guests register their own accounts.

  

  The MSM760 is connected to a Comware switch, which redirects unregistered guests to the UAM portal.

  Currently guests can reach the portal, register for their accounts, and log in. However, guests report that they cannot reach the Internet after they log in. When the administrator asks the guests to disconnect from the wireless network and then connect again, they succeed in reaching the Internet.

  What could fix this problem?

  A. In the Comware switch settings, add the guest router to the free rule list
  B. In the DHCP scope for the onboardmg VLAN, lower the lease time to about 10 seconds.
  C. Configure SOAP settings for the MSM controller on UAM.
  D. Configure the Comware switch to accept dynamic authorization updates from UAM.
  C. Configure SOAP settings for the MSM controller on UAM.
