Q204. In the switching network shown in the figure, VLAN 10 is set as the Super VLAN on the switch SWA, and VLAN2 and VLAN3 are sub VLANs of VLAN 10. VLAN, port Ethernet1/0/3 is a Trunk port, PVID is VLAN1, and all VLANs are allowed to pass; VLAN2 and VLAN20 are created on switch SWB, port Ethernet1/0/4 is a Trunk port, PVID is VLAN1, and all VLANs are allowed to pass. After setting the IP addresses of each device as shown in the figure, you can judge which of the following is correct?

PCC can communicate with PCB

PCC can communicate with SWA

PCC can communicate with SWB

SWA can communicate with SWB

Q205. As shown in the figure, SWA and SWC enable STP. SWA is the root, and SWB does not enable STP. Initially, link 2 is not connected. PCB can send data to PCA. If link 1 fails at this time, the maintenance personnel connect link 2. which of the following statement about the recovery process of the data transmission service from PCB to PCA is correct? (Multiple choice)

Since SWB does not enable STP, it takes 300 seconds by default for PCB to JPCA service recovery.

SWA will generate TCNBPDU and notify SWC. SWC will send configuration BPDU with TC set. After a period of time, the MAC address aging time of SWC and SWA will become the Forward Delay time.

SWB’s port EO/1 can enter the forwarding state immediately without delay

In this case, by default, the service from PCB to PCA can be restored after 15 seconds.

Q206. In the switching network shown in the figure, VLAN10 is set as Private VLAN on switch SWA, VLAN2 and VLAN3 are Secondary VLAN of VLAN10, VLAN2-VLAN20 is set on switch SWB, and VLAN20 is set as Private VLAN, and VLAN4 is Secondary VLAN of VLAN20. After setting the IP addresses of each device as shown in the figure, which of the following is correct for the communication between PCA and PCB?

You need to enable the local proxy ARP function in the VLAN10 view of SWA so that PCA can communicate with PCB.

The local proxy ARP function needs to be enabled in the VLAN20 view of SWB so that PCA can communicate with PCB.

PCA can communicate directly with PCB without additional configuration

The local proxy ARP function needs to be enabled in the VLAN10 virtual interface view of SWA so that PCA can communicate with PCB.
E You need to enable the local proxy ARP function in the VIAN20 virtual interface view of SWB so that PCA can communicate with PCB.

Q207. In SDN networks, which of the following security functions are currently widely used? (Multiple choice)

Q209. Two routers RTA and RTB are connected through a LAN to form a VRRP backup group. The interface configurations are as follows: RTA’s GigabitEthernet1/0.1 vlan-type dot1 q vid 2 Lp address 192.168.0.252 255.255.255.0 Vrrp vrid 1 virtual-ip 192.168.0.254 Vrrp vrid 1 priority 120 RTA’s GigabitEthernet1/0.2 vlan-type dot1 q vid 3lp address 192.168.1.252 255.255.255.0 Vrrp vrid 2 virtual-ip 192.168.1.254 Vrrp vrid 2 priority 120 RTB ‘s GigabitEthernet1/0.1 :Vlan-type dot1 q vid 2 Lp address 192.168.0.253 255.255.255.0 Vrrp vrid 1 virtual-ip 192.168.0.254 RTB’s GigabitEthernet1/0.2: vlan-type dot1 q vid 3lp address
192.168.1.253 255.255.255.0
Vrrp vrid 2 virtual-ip 192.168.1.254
The IP addresses of HostA and HostB in the LAN are 192.168.0.1 and 192.168.1.1 respectively. What can we learn from the above information? (Multiple choice)

If the backup group uses the real MAC mode, the gateway MAC address learned by HostA and HostB is the same.

If the backup group uses the real MAC mode, the gateway MAC addresses learned by HostA and HostB are not the same.

If the backup group uses the virtual MAC mode, the gateway MAC address learned by HostA and HostB is the same as

If the backup group uses the virtual MAC mode, the gateway MAC addresses learned by HostA and HostB are different.

Q210. Which of the following descriptions about VCFC License are correct? (Multiple choice)

Two License Servers are not supported for HA

After VCFC is installed, there is a 180-day trial license, and the functions are not restricted during the trial period.

After the trial license expires, you need to register the license. Currently, VCFC supports applying for authorization on the License Server.

Due to network failure or other reasons, the VCFC is disconnected from the License Server. At this time, the VCFC’s related functions will be affected immediately due to the lack of the license.

Q211. Which of the following statements about the BPDU format of MSTP is correct? (Multiple choice)

The MSTP BPDU consists of the RSTBPDU field and the MST-specific field.

If the MST region is regarded as a switch running RSTP logically, the CIST external path cost is equivalent to the root path cost of the RSTP switch.

If the MST region is regarded as a switch running RSTP logically, the CIST region root ID is equivalent to the designated bridge ID of the RSTP switch. Usually, this ID is the smallest bridge ID in the MST region.

To calculate CST, only the value of the RSTBPDU field is required

Q212. In the network shown in the figure, the interconnection lines between RT1, RT2, RT3, RT4 and RT5 are all Gigabit Ethernet lines, running OSPF, and routing interconnection after publishing the corresponding network segments. The routers all run the PIM SM protocol, and the RP is connected to the receiver on RT4, and IGMP is enabled on the corresponding interface. When the multicast meteor initially forwarded along the RPT meets the conditions for switching to the SPT, which of the following routers will receive the (S, G) join message? (Multiple choice)

RT1

RT2

RT3

RT4

RT5

Q213. Which of the following descriptions of the snmp-agent command are correct? (Multiple choice)

The nmp-agent command contains local-engine in the configuration file, so you cannot use the copy method to configure the smmp of multiple devices in the same management domain.

When the snmp-agent command is executed, if the local-engineid is not specified, the system will automatically calculate the local-engineid

The local-engineid automatically calculated by the snmp-agent command is unique, so it is recommended to keep the automatically calculated local-engineid unchanged without manually specifying it.

The local-engineid automatically calculated by the snmp-agent command may be repeated, so it is recommended to manually configure the local-engineid to keep the local-engineid of the device in the SNMP management domain unique.

Q214. After executing the display interface Ethernet 1/0/2 command on the switch SWA, the output information is as follows:
[SWA] display interface Ethernet 1/0/2
Ethernet1/0/2 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 Ethernet1/0/2 only allows data from VLAN 1 and VLAN 10 to pass through.

The current switch has only VLAN1 and VLAN10.

The data frame with VLAN1 tag will not be stripped when it leaves port Ethernet1/0/2

Data frames with VLAN 20 tags will be discarded when they enter port Ethernet 1/0/2

Q215. When the router receives multicast data, which of the following searches the multicast forwarding table? (Multiple choice)

If there is no corresponding (S, G) entry in the multicast forwarding table, the router discards the multicast data

If there is a corresponding (SG) entry in the multicast forwarding table, and the interface where the packet actually arrives matches the inbound interface in the entry, the router forwards the multicast data.

If there is a corresponding (S, G) entry in the multicast forwarding table, but the interface where the packet actually arrives does not match the inbound interface in the entry, the router discards the multicast data.

If the multicast data RPF interface does not match the incoming interface in the (SG) table entry, the router will update the incoming interface of the table entry to the RPF interface obtained by the check.

Q216. A customer purchased a router. If the performance indicators of this router are MTBFW5000 and MTTRSOQ 5, then which of the following is the reliability of this router?

99.9%

99.99%

99.999%

99.9999%

Q217. Regarding the configuration of bridge priority in spanning tree, which of the following is correct?
(Multiple choice)

The bridge priority is 16 bits in total, ranging from 0 to 65535.

If the switch is not configured with a bridge priority, the default value is 32768

The bridge priority value step is 4096

The smaller the priority value, the lower the priority of the bridge.
