HP Building HP SDN and FlexNetwork Solutions Sample Questions:

1. How does the HP Optimizer SDN Application -Microsoft Lync enhance QoS for Microsoft Lync?

A) The application pre-provisions several flows on all HP switches, which redirect all IP traffic to the HP VAN SDN Controller. Each TCP session is then assigned the correct priority before it can be established.
B) The application registers as a packet listener for all IP packets in the HP VAN SDN Controller. It creates reactive flows for all user traffic, including prioritized ones for UC&C traffic.
C) The application registers as a packet listener for TCP 5060 in the HP VAN SDN Controller. It uses packets received to create reactive prioritized flows for UC & C traffic.
D) The application receives RESTful API calls from a plug-in to Lync. It uses information obtained to create proactive prioritized flows for UC & traffic.

2. Table of Acronyms

Refer to the exhibit.

An administrator wants to establish a remote LDP session between PE-1 (loopback IP address
10.0 0.1) and PE-2 (loopback IP address; 10.0.0.2). What is required to do this?

A) Both PE-1 and PE-2 have a VPN instance that is defined with the same route distinguisher
(RD)
B) Both PE-1 and PE-2 advertise the same label for their loopback IP address
C) Both PE-1 and PE-2 use ordered mode for LDP.
D) Both PE-1 and PE-2 advertise their loopback IP address with OSPF and with LDP.

3. A company has a Unified Wired-Wireless controller solution, which uses its local portal to authenticate guests.
The company is adding an HP BYOD solution with these requirements:
-The User Access Manager (UAM) server with IP address 10.1 3.4 should provide the portal in which guests register own accounts -Guests should only have to register and log in once. After that,the guest device automatically logs inby MAC address
The administrator removes the local portal settings and begins to reconfigure the solution. What is one change that the administrator must take to the settings for the Guest SSID?

A) Apply an ACL that redirects HTTP traffic to 10.1.3.4.
B) Configure the associated WLAN-ESS interface as a hybrid port and enable MAC-based VLANs.
C) Create a domain that specifies 10.1.3.4 as the RADIUS server and define that as the portal domain.
D) Set up a remote portal server that specifies the UAM IP address and portal URL.

4. An HP Virtual Cloud Networking (VCN) SDN Application runs on an HP VAN SDN Controller. How does VCN help to provision networking for virtualized services in a cloud solution?

A) By using southbound OpenStack Layer 2 Agent APIs to set up the correct VLANs on virtual switches, as well as tunnels between virtual switches
B) By using northbound RESTful APIs to receive information from servers and switches acting as Network Functions Virtualization (NFV)-complaint routers
C) By using southbound RADIUS APIs to provision dynamic VLANs on data center switches, basing those VLANs on the customer identity
D) By using northbound Java APIs to integrate with and configure Ethernet Virtual Bridging (EVB) applications

5. An HP VAN SDN Controller runs the HP Network Protector SDN Application. The application has programmed an HP Switch with flows that output to the service insertion tunnel. How does the switch forward packets matching these flows to the controller?

A) Encapsulated in OpenFlow packets and transmitted over the auxiliary connection
B) Encapsulated in an IPSec tunnel
C) Encapsulated in OpenFlow packets and transmitted in the controller VLAN
D) Encapsulated in a GRE tunnel
