Huawei HCIE-Datacom V1.0 認定 H12-891_V1.0 試験問題:

1. There are multipleSR-MPLS TE tunnel protection mechanisms.FRR (Fast Reroute)constructs avirtual nodeto convert multiple identical route advertisement nodes into a single route advertisement node, and then computes the backup next hop of the virtual node based on theTI-LFA algorithm. In this way, traffic can be quickly switched when a fault occurs.
What is the name of this protection mechanism?

2. With telemetry, certain data can be sampled based on specific sampling paths. Which of the following sampling paths are supported by telemetry?

A) Information about the optical module on an interface
B) CPU information
C) Interface statistics
D) Memory information

3. In Huawei SD-WAN Solution, which of the following tunneling technologies is used to establish data channels?

A) IPsec
B) GRE over IPsec
C) WLAN
D) MPLS

4. In OSPFv3, which of the following types of LSAs can be flooded in the entire AS?

A) Intra-Area-Prefix-LSA
B) Inter-Area-Prefix-LSA
C) AS-external-LSA
D) Link-LSA

5. Which of the following statements is incorrect about intranet security design for a large or medium-sized virtualized campus network?

A) To secure data transmission, the CAPWAP tunnel between the AC and AP supports DTLS encryption.
B) Intranet security refers to both wired and wireless network security.
C) In addition to terminal access security, interface security must be considered during wireless network security design.
D) Traffic suppression can be configured on the wired network to block broadcast traffic by shutting down interfaces.
