A. Approved access user name and password

B. Issue the access level of access users

C. Record access traffic and duration

D. Distribute the directories accessible to users

문제5

As shown in the networking, SWA and SWB enable STP, SWC does not enable STP when initially Link 2 is not connected, PCB can send data to PCA, if Link 1 fails at this time, the maintenance personnel will connect Link 2, then The statement about the recovery process from PCB to PCA data transfer industry is correct (assuming PCA will not actively send data) __

A. Because the SWA link interruption will cause the topology change processing process, which shortens the MAC address aging time of SWA and SWB, it takes 15 seconds by default for service recovery

B. Service recovery needs to wait for the SWC MAC address to age, so the default time of 300 seconds is required

C. As SWB port E0/1 needs 30 seconds to enter the forwarding state by default, the service needs 30 seconds to recover by default

D. When the SWB port E0/1 enters the Forwarding state, the topology change processing process will be triggered, so the final restoration of the service requires the default 30+15=45 seconds

정답: B

문제6

The RRPP ring main ring 1 is formed on the customer LAN switches SWA, SWB, and SWC, which can be known from the above information

A. If the switch SWA is the master node, a Common-Flush-FDB message is sent in the Failed state to notify all transmission nodes to refresh FDB

B. If the switch SWB is a transmission node and is in the Preforwarding state, it cannot receive the Complete-Flush-FDB message from the master node within the specified time, and releases the temporarily blocked port by itself

C. If the switch SWB is a transmission node and is in the Preforwarding state, it cannot receive the CommonFlush-FDB message from the master node within the specified time, and releases the temporarily blocked port by itself

D. If the switch SWA is the master node, it sends a Complete-Flush-FDB message in the Failed state to notify all transmission nodes to refresh FDB

정답: A,B

문제7

C. 00-00-5E-82-82-01

D. 00-00-5E-02-82-01

정답: A

문제8

A. The mapping relationship between VLANs and instances in different MST regions is independent and can be different or the same

B. After the MSTI calculation is completed, the same physical port may have different roles in different instances

C. After the MSTI calculation is completed, the data flow between the domain and the domain must pass through the Master port

D. Root bridge of MSTI The root bridge of IST can be the same switch

정답: A,B,D

문제9

The switches SWA and SWB are connected together through two optical fiber Gigabit Ethernet links, and the switch SWA has the following interface configuration:
[SWA]interface GigabitEthernet 1/0/1
[SWA-GigabitEthernet1/0/1]gvrp
[SWA-GigabitEthernet1/0/1]port link-type trunk
[SWA-GigabitEthernet1/0/1]port trunk permit vlan 1 10
[SWA]interface GigabitEthernet 1/0/2
[SWA-GigabitEthernet1/0/2]port link-type trunk
[SWA-GigabitEthernet1/0/2]port trunk permit vlan 1 10
If you want to configure link aggregation to aggregate these two links together, if the configuration on the SWB is correct, you can know from the above information

A. Only by changing the configuration of GigabitEthe1/0/2 to be consistent with GigabitEthe1/0/1, can they join the same aggregation group

B. Only when GigabitEthernet1/0/2 and Gigabit1/0/1 allow all VLANs to pass, they can join the same aggregation group

C. After link aggregation is configured on both SWA and SWB, if both SWA and SWB enable MSTP on the aggregation port, GigabitEthernet1/0/1 and GigabitEthe1/0/2 can participate in forwarding

D. After link aggregation is configured on SWASWB, if both SWA and SWB enable MSTP on the aggregation port, one of GigabitEthe1/0/1 and GigabitEthe1/0/2 will be blocked

정답: C

문제10

The following statements about PIM SM are correct:

A. When receiving a registration message from a multicast source, the RP sends a join message to the multicast source, and generates an (S, G) entry when it receives traffic from the multicast source normally multicast forwarding

B. When a multicast source initially sends traffic, an (S, G) entry will be formed on the DR connected to it

C. Before the multicast traffic is normally forwarded from the RP to the multicast receiver, the routers along the way have established (*, G) entries

D. The RP will forward multicast traffic downstream only after receiving the data forwarded by the multicast source.

정답: B,C

문제11
