A.

Routes learned from L3Outs on border leaf switches are not redistributed into MP-BGP at the ingress leaf.

B.

Route control subnets control the exchange of routing information (prefixes) into and out of the fabric (Control plane)

C.

Security import subnets control the forwarding of packets into and out of L3Out connections (data plane).

D.

Routes are not redistributed to leaf switches where the same VRF is present.

QUESTION 84

In a FabricPath network, known unicast traffic is sent with the outer destination address populated with the destination SID, SSID, and local ID. Which statement describes the outer destination address in the case of unknown unicast?

 

A.

The outer destination address is a reserved multicast MAC address known as MC1 (010F.FFC2.02C0).

B.

The outer destination address is a broadcast address (FFFF.FFFF.FFFF).

C.

< font face="Arial">The outer destination address is not required because FabricPath uses the FTag to forward unknown unicast.

D.

The outer destination address is a reserved multicast MAC address known as MC1 (010F.FFC1.01C0).

 

Correct Answer: D

QUESTION 86

Which two statements about end-host mode are true? (Choose two.)

 

A.

In end-host mode, if a vNIC is hard pinned to an uplink port and this uplink port goes down, the system repms the vMIC, and the vNIC go

B.

End-host mode allows the fabric in interconnect to act as an end host to the network, representing all servers (hosts) connected to it through vNICs.

C.

End-host mode is the default Ethernet switching mode.

D.

In end-host mode, the fabric interconnect runs the 5pann,ng Tree Protocol to avoid loops.

E.

In end-host mode, if a vNIC is hard pinned to an uplink port and this uplink port goes down, the system repins the vNIC but the vNIC remain down until manual intervention.

Which statement about glean throttling in Cisco NX-OS is true?

 

A.

When forwarding an incoming IP packet in line ca
rd, if the Address Resolution Protocol request for the next hop is not resolved, the line card forwards the packets to the supervisor. The supervisor resolves the MAC address for the next hop and programs the hardware.

B.

The traffic policing feature manages the maximum rate of traffic through a token bucket algorithm. The token bucket algorithm can use the user-configured values to determine the maximum rate of traffic allowed on an interface at a given moment in time.

C.

Cisco NX-OS supports a rate-limiting feature to manages the access bandwidth policy for a network by ensuring that traffic falling within specified rate parameters is sent, while dropping packets that exceed the acceptable amount of traffic or sending them with a different priority.

D.

The traffic shaping feature in Cisco NX-OS to avoid bottle necks in the network.

 

Correct Answer: A

B.

You must manually distribute NTP authentication keys on the NTP server and Cisco NX-US devices across the network.

C.

C.CFS distributes the local NTP configuration to master only which then forwards to all devices in network.

D.

If CFS is used to distribute NTP, all devices in the network must have the different VRFs configured then as used for NTP.

 

Correct Answer: AB
