1. True or False? VLANs improve network performance by segmenting broadcast domains.
- True
- False
Explanation: The correct answer is True. A VLAN is a logical broadcast domain that can span multiple LAN segments. This can improve network performance by segmenting large broadcast domains into smaller broadcast domains. Broadcast frames are not forwarded between VLANs.
2. True or False? VLANs can improve security by isolating sensitive data from the rest of the network.
- True
- False
Explanation: The correct answer is True. Traffic generated within a VLAN remains within that VLAN and is completely separated from other parts of the network.
3. Which type of VLAN is assigned to 802.1Q trunk ports to carry untagged traffic?
- default
- native
- data
- management
Explanation: The native VLAN is assigned to 802.1Q trunk ports to carry untagged traffic.
4. True or False? It is a best practice to configure the native VLAN as VLAN 1.
- True
- False
Explanation: The correct answer is False. By default, the native VLAN is VLAN 1, however it is best practice to configure the native VLAN to be an unused VLAN.
5. Which is true of VLAN 1? (Choose all that apply.)
- All switch ports are assigned to VLAN 1 by default.
- The native VLAN is VLAN 1 by default.
- The management VLAN is VLAN 1 by default.
- VLAN 1 cannot be renamed or deleted.
Explanation: All answers are True. VLAN 1 is the default native and management VLAN. All switch ports are by default assigned to this VLAN. VLAN 1 cannot be renamed nor deleted.
