A network administrator is planning a flow table entry that provides fast failover for the traffic flow in case a link fails.
Which key element would the flow entry contain?
- A . a group identifier that specifies at least two output ports
- B . a backup set action that modifies the packet and sends it to the controller
- C . a forward action to the reserved port NEAREST_ACTIVE
- D . a go-to-table action that sends traffic to another table if the port is down
A
Explanation:
The FAST-FAILOVER group is designed specifically to detect and overcome port failures.
The FAST-FAILOVER (FF) group. A FF group is designed to detect and respond to port failures. Each bucket has a watch port/group as a special parameter, which monitors the liveness of that port or group being watched. Only one bucket is used at a time, and the bucket will only be changed if the watch port/ group of the bucket transitions from up to down. Upon such an event, another bucket will be chosen whose watch port/group indicates the link is up.

An HP switch is controlled by an HP VAN SDN Controller. An SDN application attempts to create a flow entry that forwards traffic out Port 2 on this HP switch.
However, the switch does not forward any traffic out this port. The exhibit shows the status for ports on that switch.

- A . Port 2 is part of a link aggregation with Port 1.
- B . Port 2 is down.
- C . Port 2 is placed in the discarding state by spanning tree.
- D . Port 2 does not support a VLAN on which OpenFlow is enabled.
Refer to the exhibit.

Evaluate each scenario for multi-tenant isolation, and match the scenario to the technology that best meets its needs.
Explanation:
Technologies that support multi-tenant solutions include MDC, MCE, and SPBM.
Box 1: SPBM
Over 16 million customers can each have a separate set of 4094 VLANs.
Box 2: MCE
MCE aka VRF, a single physical router can host multiple virtual routers, with separate routing tables and data planes for each customer. However, there’s a single management plane, single admin.
Box 3: MDC
MDC creates virtual devices inside a physical device. Each client has isolated ASICs, admin login and configurations, control plane, and data plane.

A company is using MCE to create a multi-tenant data center solution. Network administrators want to isolate all management functions in a VPN instance “Management”. Each switch has an IP address in 10.0.2.0/24 on its Management Ethernet port, and HP IMC manages the switches on these IP addresses.

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?
- A . by assigning the CustomerA interfaces and the specific links in the path to the same S-VLAN ID
- B . by creating a PW connection between Switch 1 and Switch 3, and mapping the CustomerA service instance to that PW
- C . by 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
- D . by changing the CustomerA I-SID 255 and defining the interface for the reserved link as the priority path in I-SID 255
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?

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?
- A . a link aggregation that consists of all of the links
- B . MSTP running on the links
- C . IRF 1, IRF 2, and IRF 3 combined into a single IRF virtual device
- D . SPBM configured across IRF 1, IRF 2, and IRF 3
C
Explanation:
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.

Exhibit 2
Network clients are configured to use the switch as their default gateway in VLAN 2. The HP Comware switch places VLAN 2 in OpenFlow instance 1. An SDN application has created the flow entry shown in Exhibit 1 to route traffic from 10.1.2.0/24 to 10.1.3.0/24. Exhibit 1 does not show the output interface for the flow.
Which output interface supports the needs of this scenario?
- A . CONTROLLER
- B . ANY
- C . NORMAL
- D . TABLE
C
Explanation:
NORMAL: Represents the traditional non-OpenFlow pipeline of the switch. Can be used only as an output port and processes the packet using the normal pipeline. If the switch cannot forward packets from the OpenFlow pipeline to the normal pipeline, it must indicate that it does not support this action.

In addition to setting up the routes between the instances, what is another requirement for this scenario?
- A . The RAGG 3 interface must be added to VPN instances “TenantA” and “TenantB.”

A
Explanation:
Network Visualizer supports integration with Microsoft Active Directory using LDAP protocol to obtain user groups which translates in user identity integration. Because of the detailed information and correlated data available to SDN, network administrators can determine the traffic that needs to be captured by filtering per user, user-group, device types, location, application, state of network, and time.
