H3C Constructing H3C High-Performance Campus Networks Sample Questions:

1. The following information is the snmp-related configuration on a H3C network device:
snmp-agent
snmp-agent local-engineid 800007DB00E0FC79887C6877
snmp-agent community read public
snmp-agent community write private
snmp-agent sys-info version all
Which description of the result of snmp access to this device is correct?

A) No matter which version is adopted, this device cannot be accessed and set up
B) You can successfully access and set up this device through snmpv2c
C) You can successfully access and set this device through snmpV3
D) You can successfully access and set up this device through snmpv1

2. Which statement is correct about the communication between switch VLANs?

A) In the figure, by default, the SWA port E1/0/1 needs to wait twice the duration of the Forward Delay before it can enter the Forwarding state
B) Both RSTP and MSTP require the designated port of the upstream device to perform rapid migration after receiving the Agreement message from the downstream device
C) In RSTP, the downstream device will respond to the BPDU with Agreement set only after receiving the BPDU with both Proposa and Agreement set to from the upstream device
D) By configuring stp no-agreement-check on the port, the MSTP switch will not check whether the Agreement bit is set in the Proposal BPDU sent upstream

3. Which statement about the STP protocol is correct?

A) STP is used to construct the shortest path between two nodes in the LAN
B) STP is used to eliminate data link layer loops in LAN
C) When the active link fails, STP can activate the redundant link and restore network connectivity
D) STP is mainly used in token ring networks

4. The two switches SWA and SWB are connected together by four Ethernet cables. The corresponding interface on the switch SVVA has the following configuration:
[SWA-Ethernet1/0/1]display this
duplex full
speed 10
[SWA-Ethernet1/0/2]display this
duplex full
speed 10
[SWA-Ethernet1/0/3]display this
duplex half
speed 100
[SWA-Ethernet1/0/4]display this
duplex half
speed 100
It can be known from the above information

A) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are Ethernet1/0/3 and Ethernet1/0/4
B) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are all four ports
C) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are Ethernet1/0/1 and Ethernet1/0/3
D) Four Ethernet ports join the same aggregation group through static aggregation, and the selected ports are Ethernet1/0/1 and Ethernet1/0/2

5. In the PIM-DM network as shown in the figure, part of the unicast routing table of routers RT1 and RT2 is as follows:
<RT1>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.0.0/16xxxxP1-1 C1-110.1.1.1POI11
1.1.1.0/24xxxxP1-2 C1-210.1.1.1Port1
<RT2>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.1.0/24XXXX P2-1 C2-111.1.1.1Port2
1.1.1.1/32XXXX P2-2 C2-211.1.1.1Port2
Then, when routers RT1 and RT2 perform Assert, the winner should be

A) If P1-2=P2-2, C1-2<C2-2, RT2 wins
B) If P1-1=P2-2, C1-1=C2-2, RT1 wins
C) If P1-2>P2-2, C1-1<C2-2, RT2 wins
D) If P1-2=P2-2, C1-2=C2-2, RT2 wins
E) If P1-1>P2-2, C1-1<C2-2, RT1 wins
F) If P1-1=P2-2, C1-1<C2-2, RT1 wins
