Huawei HCIP-Routing&Switching-IERS(Huawei Certified ICT Professional-Implementing Enterprise Routing and Switching Network) 認定 H12-221-ENU 試験問題:

1. Which types of access control lists can be divided into? (Multiple Choice)

A) Layer 2 ACL
B) Advanced access control list
C) Basic access control list
D) User-defined ACLs

2. Which of the following description of the distribution tree is correct?

A) SPT applies to both PIM-DM and PIM-SM.
B) RPT applies to both PIM-DM and PIM-SM.
C) The RP (Rendezvous Point) is root, the multicast distribution tree that the multicast group members as leaves called SPT.
D) The multicast source is root, the multicast distribution tree that the multicast group members as leaves called RPT.

3. RSTP convergence speed is faster than STP. Which of the following statements are correct? (Multiple Choice)

A) In STP, in order to avoid temporary loops, at least one forwarding delay must be waited. After all network port roles are determined, all ports can forward them.
B) Once the P/A negotiation is unsuccessful, the selection of the designated port needs to wait for two Forward delays. The negotiation process is the same as STP.
C) There is only one standard for detecting whether the topology changes in RSTP. A non-edge port migrates to the Forwarding state.
D) The P/A negotiation process can continue to be passed downstream

4. The difference between ASM and SSM of PIM-SM are? (Multiple choice)

A) After the member DR of the ASM learns the requirements of the host, it sends a Join message to the source DR directly.
B) After the member DR of the SSM learns the requirements of the host, it sends a Join message to the source DR directly.
C) SSM does not need to maintain the RP, does not need to build an RPT, and does not need to register multicast source. You can directly establish an SPT between the source and the group member.
D) ASM does not need to maintain the RP, does not need to build an RPT, and does not need to register multicast source. You can directly establish an SPT between the source and the group member.

5. Which of the following descriptions is correct about BGP Local-Preference? (Multiple choice)

A) BGP route the default value of Local-Preference is 100.
B) BGP Local-Preference is usually used in the routing rule policy to control how data flows into As
C) In BGP routing rules, the priority of MED is higher than Local-Preference, that is the priority is compared with MED.
D) In BGP routing rules, the priority of Preferred-Value is higher than Local-Preference, that is the priority is compared with Preferred-Value.
