Huawei HCIE-Routing&Switching (Written)(Huawei Certified ICT Expert-Routing & Switching) Sample Questions:
Which of the following statements about the attributes of the ISIS protocol LSP packet is correct?
- A. When the link state information increases, the packet length of the SP can be increased, so that each LSP can carry more information.
- B. Configure an intelligent timer generated by the LSP, which can automatically adjust the delay time according to the change frequency of the routing information.
- C. The LSP fast flooding feature first spreads out LSPs smaller than the specified number to speed up the synchronization process of the LSDB.
- D. Reduce the minimum interval for sending LSPs on an interface to speed up LSP diffusion.
What is the correct description of the BGP reflector? (Multiple Choice)
- A. The route reflector can advertise the routes learned from one client to other clients and non-clients.
- B. IBGP neighbor relationships need to be fully interconnected without a route reflector. The introduction of route reflectors can reduce the requirements for full interconnection.
- C. The route reflector can advertise the routes learned from the non-client to all clients.
- D. The route reflector can advertise the routers learned from IBGP neighbors to all clients and non-clients.
The network administrator defines a traffic policing strategy as follows:
[Huawei] display traffic policy user-defined
User Defined Traffic Policy Information
Policy: p1
Classifier: c1
Operator: OR
Behavior: b1
Committed Access Rate
CIR 256(kbps) , PIR 0(kbps) , CBS 48128(byte) , PBS 80128(byte)
Color Mode: color blind
Conform Action: pass
Yellow Action: pass
Exceed Action: discard
statistic: enable
The router port to which this policy is applied has been idle for about 10 seconds. At this time, there is a huge amount of burst traffic of the c1 type, then how many bytes will the packet be colored in green?
- A. 80128 bytes
- B. 32K bytes
- C. 256K bytes
- D. 48128 bytes
What do we usually call the devices in the MPLS BGP VPN domain? (Multiple choice)
- A. CP
- B. User router
- C. P
- D. PE
The following are the statements about LDP reliability, which one is wrong?
- A. LDP GR Graceful Restart uses the feature that the MPLS forwarding plane is separated from the control plane. The device does not interrupt when the protocol is restarted or the active/standby switchover is performed.
- B. The manually configured LDP FRR policy defaults to a 32-bit backup route that triggers LDP to establish a backup LSP.
- C. LDP FRR can also be used to generate an LSP for the label mapping from the non-optimal next hop. And it can be as a backup of the primary LSP to establish the transfer entries.
- D. The association between the LDP and the IGP requires the IGP to suppress the advertisement of the route and ensure that the LDP path is consistent with the IGP path.
