Switches SWA and SWB are connected together through two optical fiber Gigabit Ethernet links, and the following interface configuration is available on switch SWA:
[SWA] interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet 1/0/1] gvrp
[SWA-GigabitEthernet 1/0/1] port link-type trunk
[SWA-GigabitEthernet 1/0/1] port trunk permit vlan 1 10
[SWA] interface GigabitEthernet 1/0/2
[SWA-GigabitEthernet 1/0/2] port link-type trunk
[SWA-GigabitEthernet 1/0/2] port trunk permit vlan 1 10
From the above, we can know which of the following?

GigabitEthernet1/0/1 and GigabitEthe1/0/2 cannot be added to the same aggregation group

Only when the configuration of GigabitEthe1/0/2 is changed to be consistent with that of GigabitEthe1/0/1, can the two be added to the same aggregation group.

If MSTP is enabled on the SWA4 switch, one of GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 will be blocked.

If the SWA switch has MSTP enabled, GigabitEthe1/0/1 and GigabitEthe1/0/2 can participate in forwarding

質問 121
Which of the following statements about the principle of SmartLink & Monitor Link is correct?

SmartLink is a port linkage solution that monitors the device uplink. The Up/Down status change of the uplink triggers the Up/Down change of the downlink.

MonitorLink implements redundant backup of the primary and backup links, and enables traffic to be quickly switched to the backup link when the primary link fails.

MonitorLink sends Flush messages to notify other devices to refresh the MAC address forwarding table and ARP table entries.

SmartLink sends Flush messages to notify other devices to refresh MAC address forwarding entries and ARP entries.

質問 125
As shown in the figure, there is no connection between SWA and SWB at the beginning. SWA and SWB enable RSTP. When the topology is stable, the ports connecting SWA and SWB assume that SWA will become the new root bridge. Which of the following statements are correct? (Multiple choice)

After SWB completes the synchronization process, it will reply with an Agreement message to SWA, and its port E1/0/1 will immediately enter the forwarding state.

After receiving the Agreement message sent by SWB, SWA’s port E1/0/1 will immediately enter the forwarding state.

The designated port of SWB will continue the P/A handshake process with the downstream switch

During the P/A process, no timer will be used, so the designated port can quickly enter the forwarding state, thereby achieving rapid network convergence.

質問 126
Two routers are connected together through a LAN to form a VRRP backup group. The configuration on each interface is as follows:
[RTA-GigabitEthernet1/0] display this
IP address 192.168.0.252 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.0.254
[RTB-GigabitEthernet1/0] display this
IP address 192.168.0.253 255.255.255.0
Vrrp vrid 1 virtual-ip 192.168.1.254
What can we learn from the above information?

RTA is the Master router of the backup group

RTB is the Master router of the backup group

RTA and RTB cannot elect a backup group master router

質問 127
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
Ethernet1/0/1 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
what can we learn from the above information? (Multiple choice)

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

The data frame with VLAN1 tag will be stripped of the tag when it leaves port Ethernet1/0/1

Data frames with VLAN 20 tags can be forwarded from port Ethernet 1/0/1

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

質問 128
Regarding loop protection, which of the following is correct? (Multiple choice)

Link blocking or one-way link may cause loops

After the loop protection function is enabled, when the BPDU stored on the port ages, the loop protection takes effect.

If the role of the root port changes, it will change to the Discarding state and will not forward messages, so as not to form a loop in the network. The Discarding state will be maintained until the port receives a BPDU again and becomes a root port again.

In MSTP, this function is valid for root ports, alternate ports, and backup ports.

質問 129
As shown in the figure, SWA, SWB and SWC enable STP. If the bridge priority of SWA is set to
61440 after the topology converges, which of the following statements are correct? (Multiple choice)

After the priority is adjusted, SWA will still send configuration BPDUs with itself as the root.

After receiving the low-priority configuration BPDU, SWC will immediately respond with the configuration BPDU with itself as the root.

After the configuration BPDU saved locally by SWB ages, it will send a configuration BPDU with itself as the root to SWA.

By default, the topology will converge again after 30 seconds.

質問 130
As shown in the figure, the switches are all running RSTP. Initially, SWA, SWB and SWC are interconnected. When the topology is stable, SWB and SWD are connected. Which of the following statements are correct? (Multiple choice)

SWB will clear the MAC addresses learned on ports E0/1 and E0/2 and send RST BPDUs with TC set from these two ports.

After SWA receives the BPDU with TC set, it will clear all MAC address tables and send the RST BPDU with TC set from E0/2.

After receiving the BPDU with TC set, SWC will clear the MAC address learned on port E0/1 and send a RST BPDU with TC set from the port.

SWB will send a RST BPDU with TC set within twice the Hello Time.

質問 131
Which of the following statements about the calculation process of MSTP is correct? (Multiple choice)

Master port of the MST region-located on the regional root of the IST

Each MST region has a Master port

In the actual calculation process, the calculation of CST and IST is not in order, but is completed simultaneously.

In the actual calculation process, CIST must be calculated first, and then MSTI calculation can be performed.

質問 132
In the switching network shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN4 and VLAN20 are created on switch SWB, and VLAN20 is set as Isolate-user-vlan, and VLAN4 is set as Secondary VLA of VLAN20. After setting the IP addresses of each device as shown in the figure, if the local proxy ARP function is enabled on SWA and SWB, and SWA and SWB are allowed to send ICMP packets, then execute the command tracert 10.1.1.2 on PCA, and PCA will display the jumps required to reach PCB ()

Multicast group information maintained by the router

Number of multicast group Report messages

Multicast Group IGMP Querier

質問 134
In the switching network shown in the figure, VLAN10 is set as isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are secondary VLANs of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as isolate-user-vlan, and VLAN4 is the secondary VLA of VLAN20. After setting the IP addresses of each device as shown in the figure, which of the following statement is correct?

The PCA message enters from the GigabitEthem1/0/1 port of SWA and comes out from the GigabitEthem1/0/3 port with the VLAN Tag VLAN 1

PCA’s message comes out of SWA’s GigabitEthem1/0/3 port and enters SWB’s GigabitEthem1/0/4 port. The VLAN tag it carries is VLAN 10.

When SWB accesses PCA, the message from SWB’s GigabitEth1/0/4 does not carry a VLAN Tag

SWB’s message enters from SWA’s GigabitEthem1/0/3 port and leaves from GigabitEthem1/0/1 port with the VLAN tag VLAN10.
