NO.1

As shown in the figure, RTA, RTB, and RTC use the OSPF protocol. The default cost value is used

for links, and unicast routes converge on the entire network. The Loopback 0 interface is set to

configure RTC as the RP or BSR. The SPT switching threshold uses the default value on RTB. The

receiver joins the multicast group 225.1.1.1. The multicast source sends multicast data to the

destination address 225.1.1.1. Which interface is the inbound interface in the (10.1.1.1, 225.1.1.1)

entry on RTB?

A.

Ethernet 1/0/0

B.

Ethernet 1/0/1

C.

Ethernet 2/0/0

D.

Null

Answer:

A

NO.2

About the merits and demerits of inter- AS VPN-IPv4 Option B using MP-EBGP between ASBRs,

which statement is true?

A.

An ASBR does not store VPN routes but sends them out as label data.

B.

An ASBR is required to store all VPN routes, which challenges the performance of the ASBR.

C.

VRFs matching PEs must be configured on the ASBR.

D.

The inter-AS scheme in Option B is an inherent feature of VPN.

Answer:

B

NO.3

As shown in the figure, MPLS, MPLS TE, and MPLS RSVP-TE are configured on RTA, RTB, RTC,

and RTD. Tunnel1/0/0 and Tunnel2/0/0 are set up based on the explicit path RTA-RTB-RTC.

Tunnel1/0/0 has a hot-standby path (RTA-RTD-RTC) and an FRR path: RTA-RTD-RTC, whereas

Tunnel2/0/0 has an ordinary path (RTA-RTD-RTC) and an FRR path. Which of the following statements

are true?

A.

When the link between RTA and RTB is faulty, the state of Tunnel1/0/0 is hotstanby inuse.

B.

When the link between RTB and RTC is faulty, the state of Tunnel2/0/0 is ordinary inuse.

C.

When the link between RTA and RTB is faulty, the state of Tunnel2/0/0 is ordinary inuse.

D.

When the link between RTA and RTB is faulty, the state of Tunnel2/0/0 is FRR inuse.

Answer:

A,D

NO.4

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 all sources unicast registration information to the RP, no multicast route entries related to

source groups are generated due to receiver absence.

B.

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.

C.

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.

D.

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.

Answer:

C,D

NO.5

Which of the following can be implemented in an IP backbone network?

A.

BGP

B.

MPLS

C.

RIP

D.

ISIS

Answer:

A,B,D

NO.6

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 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.

A stub area cannot be connected using a virtual link.

C.

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

D.

Category 5 LSAs cannot be sent in a stub area.

In MPLS QoS , traffic policies are developed on simple traffic classified and complex traffic

classification policies based on simple traffic classification the service class color, and drop priority of

packet are reset based on the packet in the traffic policies on complex traffic classification measures

such as traffic classification is applied on border routers in Different domain, and traffic classification

core routers. QoS policies are configured by performing the following operations:

Defines DiffSer domain and configuring a traffic policy.

Classification traffic

Defines traffic behavior and configures characteristics of behaviors.

Defines a traffic policy and specifies for traffic categories

Applies the traffic policy

Configure L-LSP

Configures reserve address checks

Adds interface to the DiffSer domain

Which of the proceeding operations are required when you configured simple traffic classification?

A.
