  The switch shown in the exhibit should from a TRILL region. For Switch 1 interface ten1/0/22, what is a valid port link-type and TRILL port type?

  A. port link type = access port in any VLAN TRILL port type = TRILL access port
  B. port link type = access port in any VLAN TRILL port type = TRILL trunk port
  C. port link type = trunk port that permits VLMs 10 and 20 TRILL- port type = TRILL access port
  D. port link type = hybrid port with untagged VLANs 10 and 20 TRILL port type = TRILL hybrid port
  C. port link type = trunk port that permits VLMs 10 and 20 TRILL- port type = TRILL access port

• Question 4:

  A company has an HP BYOD solution with these requirements:

  

  Employees can connect their own devices to an Employees SSID, which enforces Wi-Fi Protected Access 2 (WPA2) with 802.1X.

  

  User Access Manager (UAM) is the RADIUS server for 802.1X authentication, and it enforces EAP-TLS.

  

  The employees will first connect to an open SSID, access a portal page, and download the proper certificates for completing 802.1X authentication.

  To meet these requirements, an administrator needs to deploy the correct certificate templates on UAM. What determine deploy?

  A. Whether the company uses Active Directory (AD) or Open LDAP
  B. Type of endpoint devices and the device operating systems (OS)
  C. Government regulations with which the company must comply
  D. Level of security that the company requires
  B. Type of endpoint devices and the device operating systems (OS)

  An HP Comware switch is configured with the MDC feature. It has three MDCs, which use the same CPU and are assigned these CPU weights:

  

  MDC 1 = 10

  

  MDC 2 = 4

  

  DC 3 = 2

  Currently:

  

  MDC 1 needs to use 25 percent of the CPU resources.

  

  MDC 2 needs to use 60 percent of the CPU resources.

  

  MDC 3 needs to use 60 percent of the CPU resources.

  Approximately what percentage of the CPU does each MDC receive while at the current CPU request rates?

  A. MDC 1 = 25 percent, MDC 2 = 50 percent, and MDC 3 = 25 percent
  B. MDC 1 = 63 percent, MDC 2 = 25 percent, and MDC 3 = 12 percent
  C. MDC 1 = 10 percent. MDC 2 = 4 percent, and MDC 3 = 2 percent
  D. MDC 1 = 25 percent. MDC 2 = 25 percent, and MDC 3 = 12 percent
  B. MDC 1 = 63 percent, MDC 2 = 25 percent, and MDC 3 = 12 percent

• Question 6:

  Refer to the exhibit.

  

  The exhibit shows the Fibre Channel (FQ zones that are members of zonesets on an HP Comware switch. How does this zoning affect the FC fabric operation?

  A. Host bus adapter (HBA) pWWNs in zoneset 1 belong to VSAN 1, which is currently active. HBA pWWNs in zoneset 2 belong to VSAN 2, which is inactive
  B. Server pWvVNs in zone 1 can discover targets pWWNs in zone 2. Server pWWNs in zone 3 can discover target pWWNs in zone 4.
  C. A sender pWWN in zone 1 can discover target pWWNs in zone 1. A server pWWN in zone 2 can discover target pWWNs in zone 2.
  D. The switch matches a host bus adapter (HBA) pWWN to entries in zone 1 to determine whether an HBA can connect to a port. If it does not find a match, it checks zone 2.
  D. The switch matches a host bus adapter (HBA) pWWN to entries in zone 1 to determine whether an HBA can connect to a port. If it does not find a match, it checks zone 2.

  An administrator has configured an HP Comware switch to support FCoE in Fibre Channel Forwarder (FCF) mode. A switch interface, ten1/0/1, connects to a sewer FC host bus adapter (HBA), The HBA should send storage traffic in VSAN 2, which is associated with VLAN 20.

  How should the administrator assign FC traffic for this HBA to VSAN 2?

  A. By binding a VFC interface to ten1/0/1 and specifying VSAN 2 as the VFC interface trunk VSAN
  B. By accessing the VLAN 20 configuration view and specifying ten1/0/1 as a member port of the VLAN
  C. By configuring ten1/0/1 as an F-mode FC port and specifying VSAN2 as the port access VSAN
  D. By accessing the VSAN 2 configuration view and adding ten1/0/1 as a trunk port
  C. By configuring ten1/0/1 as an F-mode FC port and specifying VSAN2 as the port access VSAN

• Question 8:

  An SDN application needs to create reactive flow table entries in response to specific packets. The flow_mod APIs will create the actual entries, but application must be configured with another API as part of this function. What is that API?

  B. A listener API that registers the application to listen for data paths
  C. A listener API that registers the application to listen for meters
  D. A sequence packet listener (SPL) API that specifies the Advisor role and the match criteria for the packets
