Your Path to Success: How to Pass the Nokia 4A0-C02 Nokia SRA Composite Exam Exam

The l-TAG in the l-SID is inspected to determine where the frame should be delivered.

When the B-MAC header is stripped the customer MAC address is then looked up in the FDB

The l-SID in the l-TAG is inspected to determine where the frame should be delivered.

The PE inspects the service label in the MPLS header before stripping the B-MAC header.

TRUE

FALSE

A frame should be sent to the PE that connects to the target site whenever possible.

A frame should be flooded as little as possible.

Customer frames should be switched based on the destination MAC address.

All of the above.

Only (a) and (b) are true.

The SDP must be configured to use GRE encapsulation.

The SDP must follow the same path as the user's SDP.

The SDP should be configured to use an RSVP signaled transport with fast reroute.

The SDP must be the same as the user's SDP.

The same as the number of alternate ports in the topology

1 per segment

The same as the number of root ports

1 per switch

Isolates collision domains.

Requires layer 2 loop prevention.

Slow response to topology changes.

Limited to 4094 vlans per switch.

Increased flooding.

The oam mac-ping will fail. The MAC address must be known in the local FDB to be successful.

The request will be flooded and the only response will come from the PE node that has learned the specified MAC address on a local SAP.

The request will be flooded and the CE device with the corresponding MAC will reply.

All nodes will reply because the oam mac-ping is flooded.

Theloopbackfuntionin802.1ag is an intrusive test that will stop customer data.

The loopback function of 802.lag is a non-intrusive "ping" sent from a MEP to a remote MEP or MIP.

The loopback function in 802.3ah is an intrusive test that will loop customer data.

The loopback function of 802.lag is an intrusive test that will "loop" all customer data back to the original sender.

TRUE

FALSE
