Question #16
Refer to the exhibit.

The switches in the exhibit are using SPBM. An administrator wants to send CustomerA traffic directly over the new link, shown by the dotted line in the exhibit, as a premium service for that customer. The existing links will be used for backup. The new link is reserved for CustomerA traffic.
How does the administrator set up Switch 1 to help to achieve this goal?

How does the administrator set up Switch 1 to help to achieve this goal?
- Aby assigning the CustomerA interfaces and the specific links in the path to the same S-VLAN ID
- Bby creating a PW connection between Switch 1 and Switch 3, and mapping the CustomerA service instance to that PW
- Cby setting up a new B-VLAN and assigning it to the new link and the backup links, and mapping the CustomerA I-SID to that B-VLAN
- Dby changing the CustomerA I-SID 255 and defining the interface for the reserved link as the priority path in I-SID 255

Question #17
Refer to the exhibit.

The switches shown in the exhibit form a TRILL region. The network administrator has enabled TRILL. What helps to ensure that Switch 2 sends multicasts and broadcasts over both of its switch-to-switch links?

The switches shown in the exhibit form a TRILL region. The network administrator has enabled TRILL. What helps to ensure that Switch 2 sends multicasts and broadcasts over both of its switch-to-switch links?
- AConfigure a switch to be the tree root bridge and allow the creation of multiple trees.
- BConfigure Switch 3 and Switch 4 with the same designated routing bridge (DRB) priority.
- CConfigure Switch 2 with multiple MSTP instances, which are mapped to TRILL access VLANs.
- DConfigure Switch 2 to enable TRILL Equal Cost Multi-Path (ECMP) globally.
Correct Answer:
D
Equal-cost multi-path routing (ECMP) is a routing strategy where next-hop packet forwarding to a single destination can occur over multiple "best paths" which tie for top place in routing metric calculations.

Question #19
A company has a data center that hosts multiple tenants. The company is adding a second and third data center. The core of each data center is an IRF virtual switch.
These are the IRF connections:
✑ IRF 1 is the core of the first data center.
✑ IRF 2 is the core of the second data center.
✑ IRF 3 is the core of the third data center.
✑ The three data centers are fully interconnected with dark fiber.
✑ IRF 1, IRF 2, and IRF 3 have connections to a WAN and to the Internet.
Which option for the connections between the data centers provides the best resiliency and stability?

✑ IRF 1, IRF 2, and IRF 3 have connections to a WAN and to the Internet.
Which option for the connections between the data centers provides the best resiliency and stability?
- Aa link aggregation that consists of all of the links
- BMSTP running on the links
- CIRF 1,IRF 2,and IRF 3 combined into a single IRF virtual device
- DSPBM configured across IRF 1, IRF 2, and IRF 3
Correct Answer:
C
IRF technology extends network control over multiple active switches. Management of a group of IRFenabled switches is consolidated around a single management IP address, which vastly simplifies network configuration and operations. You can combine as many as nine HP A-series switches to create an ultra- resilient virtual switching fabric comprising hundreds or even thousands of 1-GbE or 10-GbE switch ports.

Question #20
Refer to the exhibit.

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

A network administrator wants to connect four data centers using HP EVI. What is the correct setup for the EVI tunnel interfaces?
- Athree EVI tunnel interfaces on each EVI edge device—one EVI tunnel interface is required for each GRE tunnel in the mesh
- Bthree EVI tunnel interfaces on Switch 1, which will act as the hub, and one EVI tunnel interface each on the other switches
- Cone EVI tunnel interface on each EVI edge device–the devices automatically establish GRE tunnels between these interfaces
- Done EVI tunnel interface on Switch 1, which will be configured as the ENDP server, and no interfaces on the other switches
