Question 1

Refer to the exhibit.

As shown in the figure, RT 5 is a stub area router, an external Internet route is imported by RT 1, and a virtual connection is established between RT 1 and RT 3.At present, the Internet is accessible to routers except RT 5. Why can the Internet not be accessed from RT 5?(Select two answers)

A.The cost of the link between RT 1 and RT 3 is excessively large.

B.RT1 does not inform RT 5 that category 3 LSAs are configured by default.

C.Category 5 LSAs cannot be sent in a stub area.

D.A stub area cannot be connected using a virtual link.

Question 2

When the multicast source starts to send multicast data and no receiver joins in the RP in PIM-SM, which of the following statements are true?

A.After the source DR unicasts registration information to the RP, the multicast routing entries (S, G) of all source groups are generated in the RP but the outbound interface is null.

B.The RP receives a registration message from the source DR, creates a multicast routing entry (S, G), and sends a register stop message to the source DR.

C.After all sources unicast registration information to the RP, no multicast route entries related to source groups are generated due to receiver absence.

D.After receiving a registration message, the RP creates the multicast routing entries (*, G) of all source groups and sends a register stop message to the source DR.

Question 3

C.On a CE, configure STC for user VLANs on the user access side.

D.On a PE, configure Dot1q tunnel interfaces and simple traffic classification (STC) for interfaces on the private network.

Question 4

Which statements about the edge access layer is true?

A.It process additional value-added service and operation support for established callas.

B.It connections users to the network by providing various access means, and converts the format of information can be transmitted on the network.

C.It implement call control. With the software technology as the core, it completes basic real-time call control and connection control.

D.Using the packet technology it provides a comprehensive transport platform that boasts high reliability, quality of service (QoS) assurance, and large capacity.
