- Question
Which one of the following is true regarding VLANs?
Options- A. Two VLANs are configured by default on all Cisco switches.
- B. VLANs only work if you have a complete Cisco switched internetwork. No off-brand switches are allowed.
- C. You should not have more than 10 switches in the same VTP domain.
- D. VTP is used to send VLAN information to switches in a configured VTP domain.
- Correct Answer
- VTP is used to send VLAN information to switches in a configured VTP domain.
ExplanationSwitches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunking Protocol (VTP) is used to propagate VLAN information across a trunk link. - 1. Which class of IP address has the most host addresses available by default?

Options- A. 1
- B. 2
- C. 5
- D. 12 Discuss
- 7. What is the main reason the OSI model was created?
Options- A. To create a layered model larger than the DoD model.
