Question No: 106 – (Topic 2)

A network administrator is configuring CoS on a switch and assigns forwarding classes shown below:

class-of-service { forwarding-classes {

class best-effort queue-num 0; class bulk-data queue-num 1; class critical queue-num 3; class voice queue-num 6; class call-signal queue-num 3;

}

}

Based on the configuration, which action prioritizes call-signal traffic over critical traffic?

  1. Assign call-signal traffic and critical traffic to different schedulers.

  2. Assign call-signal traffic and critical traffic to different scheduler maps.

  3. Assign a loss priority of high to the packets in the critical forwarding class and set priority high in the scheduler configuration.

  4. Assign a loss priority of high to the packets in the critical forwarding class and configure drop profiles in the scheduler configuration.
