Q171. When the switch running MSTP and the switch running RSTP work together, the statement is correct.

The RSTP switch regards the MST domain as a logical switch, and the bridge ID is the ID of the switch directly connected to the RSTP switch in the MST domain

The MSTP switch will treat the RSTP switch as an MSTP domain composed of a single switch

MSTP switch and RSTP switch can belong to the same MST domain

MSTP switch will parse RSTBPDU into MST BPDU, where IRPC is 0

Q172. The following statements about the PIM SM joining process are correct.

As long as the DR has a local receiver of multicast group G, the DR will periodically send join messages upstream

When there is no receiver of multicast group G in the DR, the DR will send a pruning message to the upstream router

If there are still receivers in the shared network segment under the interface where the upstream router receives the pruning message, the receiver will send a group join message

Both PIMSM and PIM DM have a pruning veto process

Q173. After executing the displayinterface Ethernet 1/0/1 command on the switch SWA, the output information is as follows:
[SWA]display interface Ethernet 1/0/1
Ethernetl/0/1 current state: UP
PVID: 10
Mdi type: auto
Link delay is 0(sec)
Port link-type: trunk
VLAN passing: 1 (default vlan), 10
VLAN permitted: 1 (default vlan), 2-4094
Trunk port encapsulation: IEEE 802.1q
Port priority: 0
It can be judged from the above output

Port Ethernet1/0/1 is a Trunk port, allowing all VLAN data to pass through

Data frames with VLAN1 tags will be stripped of tags when they leave port Ethernet1/0/1

Data frames with VLAN20 tags can be forwarded from port Ethernet1/0/1

Data frames with VLAN10 tags will not be discarded when entering port Ethernet1/0/1

Q174. In the PIM-DM networking, regarding the process of SPT formation (without considering the state refresh mechanism), the correct description is:

After the process of flooding and pruning, an SPT between the multicast source and the multicast receiver is formed

The diffusion-pruning process is carried out periodically

The pruned interface no longer sends multicast packets downstream

As long as the network topology and unicast routing information remain unchanged, the formed SPT tree will not change

Q175. In the switching network as shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are Sub VLAN of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to set the IP address of each device as shown in the figure, check the MAC address table on SWA, you can judge PCC belongs to

VLAN 1

VLAN 2

VLAN 3

VLAN 10

Q176. The customer’s two switches SWA and SWB are connected together through seven Ethernet cables, and are configured with dynamic link aggregation. The corresponding ports on the switch SWA are Ethernet 1/0, Ethernet 1/0/2, and Ethernet 1/0/3 , Ethernet 1/0/4, Ethernet 1/0/5, Ethernet 1/0/6, Ethernet1/0/7 If the switches SWA and SWB only support 6 ports per aggregation group, and the SWA switch has the following configuration:
[SWA]interface Ethernet 1/0/7
[SWA-Ethernet1/0/7]lacp port-priority 4096
The LACP status output on the device is as follows:
[SWA]display lacp system-id
Actor System ID: 0x8000, 00e1-fc00-5000
[SWB]display lacp system-id
Actor System ID: 0x8000, 00e0-fc43-7384
From the above information, we can know_

In the case of the same port configuration, Ethernet1/0/1 port is the Unselected port of the aggregation group

In the case of the same port configuration, the Ethernet1/0/2 port is the Unselected port of the aggregation group

In the case of the same port configuration, Ethernet1/0/6 port is the Unselected port of the aggregation group

When the configuration of each port is the same, the Ethernet1/0/7 port is the Unselected port of the aggregation group

Q177. The following statements about BSR and RP in PIMSM are correct (choose one or more)

-There can only be one BSR in a PIMSM domain

-There can only be one C-BSR in a PIMSM domain

There can only be one RP in a PIMSM domain

-There can only be one C-RP in a PIMSM domain

Q178. In the switching network as shown in the figure, all three switches only have the default VLAN 1, the interconnection ports of the three switches are Trunk, and all VLANs are allowed to pass, and the three switches have the global and port GVRP function enabled. VLAN 10 is created on the switch SVVA, VLAN 20 is created on the switch SWC, check the status information of each Trunk port on the three switches, the correct one is displayed below (choose one or more)

[SWA]display interface Ethernet 1/0/1 Ethernetl/0/1 current state: UP …… PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

[SWB]display interface Ethernet 1/0/1 Ethernet1/0/1 current state: UP …… PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

[SWB]display interface Ethernet 1/0/2 Ethernet1/0/2 current state: UP …… PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

[SWC]display interface Ethernet 1/0/1 Ethernet1/0/1 current state: UP …… PVID: 1 Mdi type: auto Link delay is 0(sec) Port link-type: trunk VLAN passing: 1 (default vlan), 10 VLAN permitted: 1 (default vlan), 2-4094 Trunk port encapsulation: IEEE 802.1q

Q179. There are multiple IGMPv2 group member hosts (Client1/Client2/Client3) in the shared network segment, and multiple IGMPv2 routers (Router1/Router2), as shown in the following figure:
192.168.207.254 192.168.207.253
Router1 Router2
+++++
Clientl Client2 Client3
192.168.207.1 192.168.207.2192.168.207.3
So, the following statement is correct

Routerl and Router2 periodically send general group queries to the shared network segment

Only Router1 periodically sends general group queries to the shared network segment

Only Router2 periodically sends general group queries to the shared network segment

After the host receives the query message, only Clients send the Report message

After the host receives the general group query message, Client1, Client2, and Client3 may all send Report messages

After the host receives the general group query message, after the first host sends the Report message, the other hosts’ Report messages are suppressed

Q180. The customer purchases a router equipment. If the performance index of the router is MTBFW5000 and MTTRSOQ 5, the reliability of the router is

99.9%

99.99%

99.999%

99.9999%

Q181. In order to achieve efficient network management, what servers do we often need to deploy in large campus networks?

Network management server

FTP server

Telnet server

Log server

NTP server

Q182. Regarding the P/A mechanism of MSTP, the correct statement is

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

In MSTP, the downstream device only responds to the BPDU with the Agreement set when it receives the BPDU with both Proposal and Agreement set from the upstream device.

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

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

Q183. The following statements about RP election in PIMSM are correct:

The announcement message information periodically sent by the C-RP router includes the C-RP address, priority, and the range of multicast groups it serves, etc.

After the BSR collects the announcement message information, it summarizes it into an RP-Set and sends it in multicast

One RP can serve multiple multicast groups

-A multicast group can select multiple RPs for load sharing

Q184. Regarding the relationship between SuperVLAN and Sub VLAN, the following description is correct

SuperVLAN is equivalent to aggregating Sub VLANs so that all Sub VLANs share the same Layer 3 interface

SuperVLAN only establishes Layer 3 interfaces, responsible for Layer 3 forwarding of Sub VLAN

Sub VLAN only contains physical ports, and the internal host uses the address of the Super VLAN interface as the gateway

Although physical ports cannot be included in SuperVLAN configuration, after the mapping relationship between Super VLAN and Sub VLAN is established, the physical ports included in SubVLAN belong to Super VLAN

Q185. In the networking shown in the figure, the PIMSM protocol runs between RT1, RT2 and RT3, the RP is 1.1.1.1 RT3 is connected to the receiver, and IGMP is enabled on the corresponding interface, and the multicast source 2.2.2.2 is connected to View the unicast routing table on RT3 on RT2 as follows:

RT1

RT2

RT3

Q186. Which of the following statements about ring network technology is correct?

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

RRPP (Rapid Ring Protection Protocol) is a network layer protocol specifically applied to Ethernet rings

RRPR requires a dedicated hard cow, so the cost is higher

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

RT2 incoming interface list: Portl

Q188. As shown in the title picture, SWA, SWB, SWC and SWD enable STP. SWA, SWB and SWC form a loop. After the topology is stable, connect SWD and SWB. Assuming the same link overhead, the process of topology change of STP is The following statements are correct

SWD will send TCN BPDUs from port E0/1

SWB will send TCN BPDU from port E0/2

If the link between SWC and SWA is interrupted, SWC will send out TCN BPDU from port E0/3

If the link between SWB and SWC is interrupted, both SWB and SWC will send TCN BPDUs from port E0/2

Q189. Regarding root bridge protection, the following statements are correct:

When root bridge protection is not configured, the root bridge will lose its status as the root bridge if it receives a higher priority BPDU

After the root bridge protection is configured, the ports receive high-priority BPDUs, and the status of these ports will be set to Listening and no longer forward packets

The port will undergo a transition from the Listening state to the Forwarding state. During this period, if the port does not receive a better BPDU, the port will resume its original forwarding state.

Root bridge protection is configured in port view

Q190. In the switching network as shown in the figure, VLAN 10 is set as Super VLAN on the switch SWA, VLAN 2 and VLAN 3 are Sub VLANs of VLAN 10, Port Ethernet1/0/3 is a Trunk port, PVID is VLAN 1, allowing all VLANs to pass ; Create VLAN2~VLAN20 on the switch SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to pass, after setting the IP address of each device as shown in the figure, the following statement is correct
