H3C Constructing H3C High-Performance Campus Networks GB0-371-ENU Prüfungsfragen mit Lösungen:
1. Regarding the relationship between RSTP and STP, the correct statement is
A) RSTP has all the functions of STP, but it only uses one type of BPDU
B) RSTP is defined in the old EE802.1 D standard, and its protocol thinking is the same as STP, but the convergence time is improved
C) The switch running RSTP can work with the switch running STP and improve the convergence time of STP
D) RSTP can implement load sharing of data of different VLANs on Trunk links on the basis of STP
2. The advantages of modular network architecture include (choose one or more)
A) It is allowed to dynamically call IT resources through open interfaces to realize a standard, compatible, safe, intelligent and manageable IT application environment
B) It replaces the traditional hierarchical network model to facilitate network planning and deployment
C) Each module can be planned and deployed separately. The function of the network can be added or removed by adding or deleting modules, which is conducive to building a complex network
D) Allow different application functions or application systems to share data, resources and capabilities, and participate in business processes
3. The following statements about multicast routing protocols are correct:
A) Intra-domain multicast routing protocols include: MSDP, DVMRP, MOSPF, PIM
B) In dense mode, the multicast data stream is flooded from the multicast source to every corner of the network by pushing, and the multicast receiver passively receives multicast packets
C) The multicast routing protocol has two modes: dense and sparse
D) In sparse mode, the multicast data stream is sent from the multicast source to the multicast receiver in a pull mode, and the multicast receiver actively sends and receives requests
4. In the network connection shown in the figure, SWA and SWB are Layer 3 switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and Master of VRRP, and SWC is the Layer 2 switch connected to the access terminal , The following description about network link failure is correct
A) When the link between SWA and SWB is interrupted, the topology of STP will change, and both upstream ports of SWC will become Forwarding
B) When the link between SWA and SWB is interrupted, the VRRP Master will switch, and SWB will become the new VRRP Master
C) After the link between SWA and SWC is interrupted, the VRRP Master will remain unchanged, but the SWC downstream terminal will not communicate with the gateway.
D) When the link between SWA and SWC is interrupted, the topology of STP will change, and G1/0/2 of SWC will become Forwarding
5. The customer requires that during network design, there must be high-reliability equipment in key parts, and the reliability of the equipment should reach 99.999%.
A) MTBF>Y699^; MTTR<U1
B) MTBF>Y28 years; MTTR<U1
C) MTBF>Y343^; MTTR<U1
D) MTBF>Y9 years; MTTR<U1
