18. Which three statements are typical characteristics of VLAN arrangements? (choose three)
Answer
  • A new switch has no VLANs configured.
  • Connectivity between VLANs requires a layer 3 device
  • VLANs typically decrease the number of collision domains
  • Each VLAN uses a separate address space

Image:
61b461d3-920c-40df-b955-f36aa38712b4 (image/png)
Answer
  • Only the host in VLAN 1 on the two switches will be able to communicate with each other
  • The host in all VLANs on the two switches will be able to communicates witch each other
