Decommissioning requires safe shutdown, data clearing, proper disposal, and documentation.

Question 6: Why is co-channel interference (CCI) a significant concern when deploying multiple access points using the same channel?

It causes APs to automatically reboot
APs on the same channel compete for air time, degrading throughput for all connected clients (Correct answer)
It only affects 5 GHz networks, not 2.4 GHz
It reduces the physical range of each access point

Correct answer: APs on the same channel compete for air time, degrading throughput for all connected clients

Co-channel interference occurs when multiple APs share the same channel, causing them to contend for medium access and reducing overall network throughput.

Encourage capable clients to connect on the 5 GHz band (Correct answer)
Prevent clients from roaming between APs
Force all clients to the 2.4 GHz band for wider coverage

Correct answer: Encourage capable clients to connect on the 5 GHz band

Band steering nudges dual-band capable clients toward the 5 GHz band to reduce congestion on the 2.4 GHz band.

Regular safety drills ensure that all personnel are prepared to respond effectively during actual emergencies.

Question 24: Which feature helps isolate clients on a public Wi-Fi?

Client isolation (Correct answer)
DHCP binding
SSID hiding
MAC filtering

Correct answer: Client isolation

Client isolation is a security feature commonly used on public Wi-Fi networks. It prevents wireless clients connected to the same access point from directly communicating with each other.

Blocks low-bandwidth devices
Prevents data encryption
Increases overall bandwidth
Prioritizes important network traffic (Correct answer)

Correct answer: Prioritizes important network traffic

QoS (Quality of Service) is a set of technologies that manage and prioritize network traffic to ensure that critical applications and services receive the necessary bandwidth and low latency. By assigning higher priority to traffic like voice calls or video streaming, QoS prevents congestion from less time-sensitive data. This optimization improves the user experience for essential services by ensuring consistent performance.

Question 28: What does EIRP stand for in the context of wireless networking?

Enhanced Interference Reduction Protocol
External IP Routing Protocol
Effective Internal Radio Power
Equivalent Isotropically Radiated Power (Correct answer)

Correct answer: Equivalent Isotropically Radiated Power

EIRP (Equivalent Isotropically Radiated Power) is the total power radiated by an antenna system, combining transmit power and antenna gain.

Question 29: A wireless network is experiencing slow performance because many legacy 802.11b clients are connected. What feature can the administrator enable to improve performance for newer clients?
