PADS

PADR

PADO

PADT

NO.39 Which of the following statements regarding the description of LDP is incorrect?

Between two LSRs that run LDP, the LDP session is established and Label/FEC mapping information is exchanged.

In MPLS, LDP is used to implement label distribution, label control and label retention.

The two routers between which LDP session is established are called LDP Peer.

The UDP and TCP port number for LDP is 64.

NO.40 Assuming that a router which only supports IP Precedence receives a packet marked with DSCP, which of the following statements is correct?

The last three bits of DSCP are set to 101.

Eight levels of AF in DSCP are mapped into eight levels of IP Precedence.

The first three bits of DSCP are mapped into three bits of IP Precedence.

All 8 bits of TOS are set to zero.

NO.41 When configuring Diff-Serv in QoS, the edge router on Diff-Serv network classify packets according to its source address, destination address or other parameters, assigning different IP precedence for different packets, while other routers classify packets according to IP precedence.

True

False

NO.42 Which of the following statements is correct regarding Hellolnterval in OSPF?

The range of Hellolnterval is from 0 to 65535.

Hellolnterval can be modified by administraor.The smaller the value, the faster (he topology change discovery.

Hellolnterval is 10 seconds for NBMA and broadcast network by default.

Hellolnterval is 30 seconds for P2P and P2MP network by default.

NO.43 Which of the following statements regarding Attachment Bit are correct?

After the Level! router receives Level-1 LSP with Attachment bit set to 1, it will generates default route with the nearest Level-1-2 router as the next hop.

The Attachment Bit can be generated by the Level-2 or Level-1-2 router.

The Attachment Bit can be generated in Level-2 LSP.

The Attachment Bit is carried In Level-1 LSP generated by Level-1-2 router connected to another area.

NO.44 Which of the following are the features of Huawei IPRAN solution?

Supports Layer 3 networking and smooth evolution to LTE, protecting customers’ investment.

One network, one set of O&M, full service bearing, lowest network construction cost and O&M cost; Visualized O&M, Reducing O&M Costs and Simple and Efficient.

Oriented to FMC and Adapted to Future Development Requirements.

Based on a unified router platform and a unified VRP platform, IP RAN is compatible with PTN products.

NO.45 BGP Is an exterior gateway protocol which runs among ASs. It focuses on routes control and selection of optimal routes rather than discovery and calculation of routes.

True

False

NO.46 Which of the following statements are correct?

Both TE FRR and VPN FRR are used to protect tunnels, and therefore they can replace each other.

After VPN FRR is deployed, the end-to-end service convergence time is shorter than 1 second.

TE FRR Implements quick traffic switchovers if a PE becomes faulty.

VPN FRR implements quick traffic switchovers if a PE becomes faulty.

NO.47 There are two MAC address learning modes in the VPLS: unqualified and qualified. In qualified mode, all VLANs are processed by the same VSI and they share the same broadcast domain or MAC address space.

True

False
