HP HP0-Y51 Exam Questions & Answers

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

A. 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 UCandC traffic.

B. 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.

C. The application receives RESTful API calls from a plug-in to Lync. It uses information obtained to create proactive prioritized flows for UC and traffic.

D. 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 and C traffic.

A company is considering TRILL and SPBM as options for the data center architecture. The company is interested in how the solution handles load-balancing unicast traffic. What correctly describes the TRILL and SPBM options?

A. TRILL can use Equal Cost Multi-Path (ECMP). SPBM selects one best path to each SPBM switch in each B-VLAN, but can select different paths for different B-VLANs

B. SPBM can use Equal Cost Multi-Path (ECMP). TRILL does not support ECMP for unicasts, but can load-balance multicast, depending on the tree configuration.

C. Neither SPBM nor TRILL can use Equal Cost Multi-Path (ECMP). Both technologies can send traffic for different VLAN VLANs or I-SIDs on different links.

D. Both SPBM and TRILL can use Equal Cost Multi-Path (ECMP) to load-balance unicasts. provided that ECMP is enable at hardware level.
