Question: 9

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

When forwarding an incoming IP packet in line card, 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.

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.

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.

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