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

Refer to the exhibit.

An HP provision switch has OpenFlow table entries indicated in the exhibit.

The switch should forward most traffic between 10.1.10.0/24 and 10.1.20.0/24 on port 1. However any IP traffic between server 1, at 005056-111111 and

10.1.10.10, and server 2, at 005056-222222 and 10.20.20, should be forwarded on port 2.

Which change to the rules let the switch behave as desired?

A. For flow 3, the table ID is set to 200, and the priority is set to 47000

B. For flow 4, the priority is set to 47000

C. For flow 4, the table ID is set to 100, and the priority is set to 47000

D. For flow 3, the instruction is set to Write Actions output 1

An administrator wants to connect four data centers using HP EVI. What is the correct setup for the EVI tunnel interfaces?

A. Three EVI tunnel interfaces on each EVI edge device-one EVI tunnel interface is required for each GRE tunnel in the mesh

B. One EVI tunnel interface on Switch 1, which will be configured as the ENDP server, and no interfaces on the other switches

C. Three EVI tunnel interfaces on Switch 1, which will act as the hub. and one EVI tunnel interface each on the other switches

D. One EVI tunnel interface on each EVI edge device--the devices automatically establish GRE tunnels between these interfaces

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

An administrator is setting up an EVI solution on four HP Comware switches. The switches reach each other on these IP address:

Switch1 = 10.1.1.1

Switch2 = 10 2.2 2

Switch3 = 10.3.3.3

Switch4 = 10.4.4.4

The administrator wants to make Switch1 and Switch2 potential EVI Network Discovery Protocol (ENDP) servers. What is the proper configuration on the Switch1 EVI tunnel interface?

A. evi neighbor-discovery server enable evi neighbor-discovery client enable 10.1.1.1

B. evi neighbor-discovery server enable evi neighbor-discovery client enable 10.2.2.2

C. evi neighbor-discovery client enable 10.3.3.3 evi neighbor-discovery client enable 10.4.4.4

D. evi neighbor-discovery client enable 10.3.3.3 evi neighbor-discovery client enable 10.4.4.4

Which OpenFlow use case is an example of Network Functions Virtualization (NFV)?

A. Use OpenFlow to deploy configurations using IMC VAN SDN Manager.

B. Use OpenFlow to implement a router on an open-vswitch.

C. Use OpenFlow to replace the need of an snmp-agent on the switch.

D. Use OpenFlow to implement traffic prioritization on the edge.

Refer to the exhibit.

A company has two HP Unified Wired-Wireless controllers. The MSM APs in Area 1 in the exhibit are controlled by Controller1. The MSM APs in Area 2 in the exhibit are controlled by Controlled. The company purchases a Controlled to provide backup for both Controller1 and Controller2 (N+1 redundancy).

How does the administrator set up the APs in Area 1 so that they contact Controlled if Controller1 fails?

A. Create a roam group that includes Controller1, Controlled, and Controlled. Make sure that Controlled has the highest IP address

B. Create AP templates for the area 1 APs on Controlled and set its connection priority for these APs to 7.

C. Create a backup AC configuration group between Controller1 and Controlled. Enable Fast Backup on the group.

D. On Controller1, configure the new controller's IP address as the backup controller for the APs

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

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.

A Company has APs that are deployed relatively close together. These APs are controlled by an HP Unified Wired-Wireless controller. Which setting helps to prevent the APs from interfering with each other while also letting the APs extend their coverage area if one of the AP fails?

A. Channel reuse

B. Dynamic frequency selection (DFS)

C. Transmit power control (TPC)

D. Fair scheduling
