- 8.Which one of the following statements is true regarding STP?
- A.
STP is used to defend against spoofing attacks.
- B.
STP is used to maintain the VLAN configuration consistency across the Layer 2 network.
- C.
STP is used to prevent loops from being formed when switches or bridges are interconnected via multiple paths across the Layer 2 network.
- D.
STP is used to negotiate whether an interconnection between two switches should be put into access or trunk mode.
- E.
STP is used to detect the loss of bidirectional communication on a link.
- 9.Which two of the following statements are true regarding standalone and lightweight access points? (Choose two.)
- A.
Lightweight access points are self-contained, each offering one or more fully functional BSSs.
- B.
Standalone access points can be configured one-by-one and offer complete functionality by themselves.
- C.
Lightweight access points rely on a central wireless LAN controller to retrieve their configurations.
- D.
Lightweight access points are also known as autonomous access points.
