Huawei HCNP-R&S Fast Track 認定 H12-224-ENU 試験問題:

1. Which of the following statements regarding OSPF external route types is false?

A) OSPF includes Type 1 and Type 2 external routes.
B) A Type 2 external route is always preferred over a Type 1 external route when other conditions are the same.
C) The cost of a Type 1 external route is the addition of the AS external cost and the AS internal cost (the cost from a router to an ASBR).
D) The cost of a Type 2 external route is the AS external cost.

2. Which of the following statements regarding BGP Update messages is false?

A) Update messages are sent in multicast mode.
B) Generally, Update messages are sent after Keepalive messages.
C) Update messages can be used to advertise multiple reachable mutes.
D) Update messages are used to exchange routing information between BGP peers.

3. Which of the following statements regarding AS_Path is false?

A) AS_Path is a very important well-known mandatory attribute in BGP.
B) AS_Path is a list of ASs that a BGP route passes through.
C) When a router has two or more routes to the same destination, the router compares the AS_Path attributes of these routes and prefers the route with the longer AS_Path attribute.
D) BGP does not accept the routes whose AS_Path attribute contains the local AS number.

4. Which of the following statements regarding the STP configuration is true?

A) STP automatically runs by default and therefore does not require configuration.
B) The STP convergence speed is slow, which may cause network interruption. Therefore, disabling STP is a preferred solution.
C) For routine STP configuration, the position of the STP blocked port is controlled to ensure that the blocked port is not located on a backbone link or device.
D) Similar to the implementation of routing protocols, data flows between switches can be adjusted by modifying link costs.
E) The RSTP algorithm is simple and reliable and supports fast convergence. Therefore, all switches on the network are configured to work in RSTP mode.

5. MPLS performs different actions on labels.
What is the meaning of the pop action?

A) The top label is added to the MPLS label stack.
B) The top label is replaced with another value.
C) The top label is replaced with the label of another group.
D) The top label is removed from the MPLS label stack.
