Question

A wireless networking topology in which client devices communicate directly with each other without the use of a controlling Access Point (AP) is called:

a. IEEE 802.3af
b. Star topology
c. Ad hoc mode
d. IEEE 802.3at
e. Infrastructure mode

Answer 1

The correct answer is c. Ad hoc mode, where client devices communicate directly with each other without an Access Point. This mode is distinct from Infrastructure mode, which uses an AP, and unrelated to the IEEE 802.3af/at PoE standards or the Star topology.

Step-by-step explanation:

The wireless networking topology you are asking about, where client devices communicate directly with each other without the use of a controlling Access Point (AP), is referred to as c. Ad hoc mode.

In Ad hoc mode, each device in the network can communicate directly with any other device in the network. This mode does not require an access point or a connection to a traditional wired network. It is useful for establishing a network quickly and for temporary situations. In contrast, Infrastructure mode requires the use of an Access Point to manage network traffic, and is typically found in most home and business Wi-Fi networks.

Neither IEEE 802.3af nor IEEE 802.3at, which are standards associated with Power over Ethernet (PoE), nor the Star topology, which is a type of network topology where each device is connected to a central hub, are correct in the context of this question.
