Huawei HCIE-Routing&Switching (Written)(Huawei Certified ICT Expert-Routing & Switching) Sample Questions:

1. In the aggregate ipv4-address { mask | mask-length }[ as-set | attribute-policy route-policy- name1 | detail-suppressed | origin-policy route-policy-name2 | suppress-policy route-policy- name3 ] command, multiple parameters can be specified to affect the route summarization process and results.
Which statements about this command are true? (Multiple Choice)

A) If suppress-policy is configured, the summarized route can be generated, the if-match clauses of the route-policy can be used to selectively suppress specific routes. Those specific routes that match this route-policy will still be advertised to other BGP peers.
B) If origin-policy is configured, only the specific routes that match the route-policy are used to generate the summarized route.
C) If as-set is configured, the AS_Path of the generated summarized route contains AS_Paths of all specific routes. This avoids routing loops.
D) If attribute-policy is configured, attributes can be set for the summarized route.

2. Which of the following statement about the NSSA area is correct?

A) The NSSA region will automatically generate a default LSA to access the external network.
B) The NSSA region generates Type 7 LSA to inform external routing, and the FA address role in the Type 7 LSA is to prevent loops
C) In the hello message sent by OSPF neighbor in NSSA region, position N is 1 and position E is 0 in option field
D) In the hello message sent by OSPF neighbor in NSSA region, position N is 0 and position E is 1 in option field.

3. Which of the following descriptions are true about the establishment process of LDP LSP? (Multiple Choice)

A) By default, the LSR is for the same FEC. The received label mapping can only come from the optimal next hop. It cannot be from the non-optimal next hop.
B) The process of establishing an LSP is actually the process of binding the FEC to the label and advertising the binding to the upstream LSR of the LSP.
C) When the network topology changes cause the next hop neighbor to change, the LSR can directly reestablish the LSP by using the label sent by the original non-optimal next hop neighbor.
D) In the label publishing DoD mode, for a specific FEC, the LSR does not need to obtain the label request message from the upstream to perform label distribution and distribution.

4. As shown in the configuration, if the administrator configures OSPF on R1 but R1 cannot learn the routes of other routers, what are the possible reasons? (Multiple Choice)
[R1] ospf
[Rl-ospf-1] area 2
[R1-ospf-1-area-0.0.0.2] network 10.0.13.1 0.0.0.0

A) The area ID configured by this router is different from the area ID of its neighbor router.
B) This router is not configured with an OSPF process ID.
C) This router is not configured with authentication, but the neighbor router is configured with authentication.
D) The router's announcement network address does not match the interface mask

5. To enable the routers at both ends of the IPv6 over IPv4 manual tunnel to exchange routing information, you can enable OSPFv3 on the tunnel. OSPFv3 can form a neighbor relationship and use the tunnel interface as a P2P tunnel interface.

A) True
B) False
