H3C Constructing H3C High-Performance Campus Networks 認定 GB0-371-ENU 試験問題:

1. Which of the following statements about ring network technology is correct?

A) RRPR requires a dedicated hard cow, so the cost is higher
B) RRPP (Rapid Ring Protection Protocol) is a network layer protocol specifically applied to Ethernet rings
C) Ethernet ring technology is becoming more mature and low in cost. The technologies to solve the problem of layer 2 network loops include RPR and RRPP
D) The convergence time of RRPP has nothing to do with the number of nodes on the ring network, and can be applied to networks with larger network diameters

2. Regarding the MSTP calculation process, the correct statement is

A) The Alternate port and Backup port on the CST must be domain boundary ports and must not be in the MST domain
B) The calculation process of MSTP is to first calculate CST and IST through MSTBPDU, and then the switches in the domain send MSTI BPDU to calculate the spanning tree of each instance
C) In MSTP, since the ports at both ends of the link may be designated ports in different instances, the ports at both ends of the link may both receive and send MST BPDUs at the same time
D) When calculating CST, the external path cost will be given priority, and the internal path cost will be compared only when the external path cost is the same

3. To configure the Ethernet1/0/1 port of the switch SWA as a hybrid port, its PVID is VLAN20, and when sending VLAN20 data frames without tagging, when sending VLAN 10 data frames, then the following configuration Is the process correct (choose one or more)

A) [SWA]vlan10 [SWA-vlan 10]quit [SWA]vlan 20 [SWA-vlan20]quit [SWA]interface Ethernet 1/0/1 [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1 /0/1 ]port hybrid vlan 10 tagged
B) [SWA]vlan10 [SWA-vlan10]quit [SWA]vlan 20 [SWA-vlan20]quit [SWA]interface Ethernet 1/0/1 [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged [SWA-Ethernet1 /0/1 ]port hybrid vlan 20 untagged
C) [SWA]interfaceEthernet 1/0/1 [SWA-Ethernet1/0/1]port link-type hybrid [SWA-Ethernet1/0/1]port hybrid pvid vlan 20 [SWA-Ethernet1/0/1]port hybrid vlan 10 tagged [SWA-Ethernet1/0/1]port hybrid vlan 20 untagged [SWA-Ethernet1/0/1]quit [SWA]vlan 10 [SWA-vlan10]quit[SWA]vlan 20
D) [SWA]vlan10 [SWA-vlan 10]quit [SWA]vlan 20 [SWA-vlan20]port Ethernet 1/0/1 [SWA-vlan20]quit [SWA]interface Ethernet 1/0/1 [SWA-Ethernet1 /0/1 ]port link-type hybrid [SWA-Ethernet1 /0/1]port hybridvlan 10 tagged
E) None of the above is correct

4. Regarding the rapid switching mechanism of designated ports in RSTP, what are the correct statements?

A) When the designated port in RSTP is in Discarding state, RSTBPDU with Proposal set to be sent
B) The designated port fast switching mechanism must be on the point-to-point link
C) The designated port receives the RST BPDU with the Proposal bit set, and the disadvantage is that this port is a follower port, the port will send the RST BPDU with the Agreement bit set
D) The purpose of the synchronization process is to eliminate the possibility of loops locally on the bridge, and all designated ports need to be blocked during the synchronization process

5. Which of the following statements about SOA and ITolP are correct?

A) ITolP solution embodies the core idea of SOA
B) SOA solutions require the integration of IT infrastructure and the establishment of a unified IT infrastructure platform based on network technology
C) SOA is based on the network, eliminates the information gap caused by heterogeneous systems, integrates various services such as storage, security, and multimedia, and realizes the componentization and resourceization of IT infrastructure
D) ITolP allows flexible, fast and efficient construction of enterprise intelligent applications, and can quickly adapt to changes in enterprise business processes
