Question 2

According to the SAP-egress policy configured and applied, which queue will EF traffic use?

AQueue 2 in 'policer-output-queues,' the default queue group used by policers on egress, because there are no queues in the 'qg-10' queue-group template.

BThe local SAP's queue 1, because there is no queue in the 'qg-10' queue-group template for EF traffic.

CQueue 1 in the 'qg-10' queue-group, because it exists by default and all traffic is mapped to it.

DEF traffic is dropped because there are no queues in the 'qg-10' queue-group template.

Question 3

By default, how does a hybrid port on a Nokia 7750 SR share its allocated buffer space between access and network pools?

AAll buffer space is initially allocated to access pools, and some of it is reallocated to network pools if network interfaces are configured on it.

BAll buffer space is initially allocated to network pools, and some of it is reallocated to access pools if service SAPs are configured on it.

CBuffer space is allocated 50% for access pools and 50% for network pools.

DBuffer space is allocated 25% for access pools and 75% for network pools.

Question 5

Which of the following about self-generated traffic QoS is TRUE?

AThe DSCP marking stays ncl for all applications; only the internal forwarding class is manipulated across different applications.

BDSCP bits can be set per application, per routing instance.

CThe internal forwarding class for self-generated traffic is set once and applied to the base router and all VPRN instances.

DSelf-generated traffic can be marked at Layer 2 no matter what encapsulation is used on the network interfaces.
