Wireless Networking

Which characteristic best describes an Independent Basic Service Set (IBSS) connection?

• It requires an access point for communication.

• Devices communicate indirectly through a central server.

• It is created for a particular purpose without any previous planning.

• It is primarily used for long-term, stable network connections.

What is the primary distinction between an SSID and a BSSID in a wireless network?

• SSID is the hardware address of an access point, while BSSID is the network name.

• SSID is the network name that users see, while BSSID is the unique hardware address of an access point.

• Both SSID and BSSID refer to the same network identifier.

• BSSID is used for temporary connections, whereas SSID is for permanent ones.

What is the main benefit of using an Extended Service Set Identifier (ESSID) in a wireless network?

• It provides a unique name for each individual access point.

• It requires devices to manually reconnect when moving between different access points.

• It enables seamless roaming for devices as they move between multiple access points sharing the same network name.

• It restricts network access to only a single, designated access point.

What is the primary purpose of a captive portal in a wireless network?

• To encrypt all data transmitted over the network.

• To allow direct device-to-device communication without an access point.

• To authenticate users and often require agreement to terms before granting full network access.

• To automatically configure the wireless security mode for connected devices.

What is a key difference between WPA/WPA2/WPA3-Personal (PSK) and WPA/WPA2/WPA3-Enterprise (802.1X) wireless security modes?

• Personal mode uses individual user credentials, while Enterprise mode uses a pre-shared key.

• Enterprise mode requires no authentication, while Personal mode requires a password.

• Personal mode uses a pre-shared key for all users, while Enterprise mode authenticates users individually with a server.

• Enterprise mode is less secure than Personal mode due to shared credentials.

Which characteristic best describes an omnidirectional antenna?

• It focuses the wireless signal in a single direction.

• It distributes the wireless signal evenly on all sides.

• It is primarily used for connecting different buildings over long distances.

• It requires a separate authentication server for user access.

How is antenna performance measured in dB (decibels) related to power?

• Every 1 dB of gain triples the power.

• Every 3 dB of gain doubles the power.

• Every 10 dB of gain halves the power.

• dB gain is only relevant for omnidirectional antennas.

What is a primary distinction between autonomous and lightweight access points?

• Autonomous access points are managed by a central controller, while lightweight access points are standalone.

• Lightweight access points handle most wireless tasks, while autonomous access points rely on a switch.

• Autonomous access points are standalone devices, while lightweight access points rely on a switch for intelligence and configuration.

• Lightweight access points are more expensive and complex to deploy than autonomous ones.
