-
Which statements are true? (Choose three.)
- The sub-VLANs are configured in the super VLAN view.
- VLANs 1 to 4094 can be configured as a super VLAN.
- The aggregate-vlan command is used to configure the super VLAN.

- SWA
- SWB
- SWC
- None of the above
-
Which statements about the VLAN on S series switches are true? (Choose two.)
- The VLAN IDs on the switch range from 1 to 4090.
- The switch has a default VLAN.
- The priority value in the VLAN tag can be changed on the switch.
- A VLAN tag contains one byte.
-
As shown in the figure, port 1 of switch A is configured with the Fixed mode, and other ports are configured with the Normal mode. The trunk interfaces allow all VLANs. Which VLANs are registered on port 1 of switch C? (Choose three.)
- VLAN 1
- VLAN 5 to VLAN 10
- VLAN 15 to VLAN 20
- VLAN 25 to VLAN 30
-
In STP configuration, which statement about BPDUs is true?
- BPDUs cannot be sent from the designated port.
- BPDUs can be sent only from the designated port.
- BPDUs can be sent from any port.
- None of the above.
-
Which statements about the relationship between GVRP and GARP are true? (Choose two.)
- GVRP, GARP, and GMRP are the standards of the same type.
- GVRP and GARP are defined by IEEE 802.1p.
- GVRP is based on GARP, and is an application of GARP.
- GVRP is a new definition of GARP.
-
On an RSTP network, when an edge port is in protected state, what operation is performed after the edge port receives BPDUs?
- The edge port forwards BPDUs.
- The edge port discards BPDUs.
- The edge port is shut down.
- The edge port obtains required information from BPDUs.
-
The dot1x authentication-method command is used to set the 802.1x authentication mode.
Which is the most secure authentication mode?
- PAP
- EAP
- CHAP
- EAP-TTLS
-
When the topology of a network running RSTP changes, what happens after the change?
- Flooding on the entire network.
- The aging time of MAC address entries is changed.
- Some MAC address entries are deleted.
- All of the above
-
The port isolation function can isolate the ports on the same switch.
- True
- False
-
Which statement about VLAN mapping is true?
- The interface configured with VLAN mapping must be a hybrid interface.
- The same VLANs on different interfaces cannot be mapped to different VLANs.
- Different VLANs on the same interface can be mapped to the same VLAN.
- Any types of interfaces can be configured with VLAN mapping.
-
Which problems on a single spanning tree network can be solved by MSTP? (Choose three.)
- Traffic forwarding paths in some VLANs are faulty.
- Traffic cannot be load balanced.
- The second best path problem may occur.
- The network reliability cannot be improved.
