Question # 21

The MDU attached to this PE has been configured with active/standby SDP's configuration option has been configured for the PE to recognize that this SDP is in standby mode?

Options:

A.

On the PE the endpoint has been configured with "supress-standby-signalling"

B.

On the PE the endpoint has been configured with "no supress-standby-signalling"

C.

On the MDU the endpoint has been configured with "supress-standby-signalling"

D.

On the MDU the endpoint has been configured with "no supress-standby-signalling1

Questions # 22:

How can one ensure that a specific switch will be select as root in an STP network?

Options:

A.

Set the bridge priority to 131071.

B.

Set the bridge priority to 0.

Question # 23

Assume there are two VPLS services configured on the MDU. How could load-balancing be achieved when using Active/Standby pseudowires?

Options:

A.

This cannot be done.

B.

Each VPLS will use the same pair of SDP's with the same endpoint configured with the option "load-balancing 2".

C.

Each VPLS will need their own pair of spoke-SDP's configured. The spoke-sdp's that are to be active should be configured with the option "precedence primary".

D.

Under the end-point configuration, enable load-balancing 2 and the MDU will load balance automatically.

B.

Adding or removing a SAP may require several network touches.

C.

Adding or removing a service may require several network touches.

D.

Adding or removing an Epipe may require several network touches.

E.

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

B.

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

C.
