A pre-deployment site survey helps in identifying the best locations for APs to ensure optimal coverage, capacity, and minimal interference.

A spectrum analyzer is used to measure the RF spectrum and detect interference, helping in planning the wireless network layout.

MRI machines can cause significant RF interference, so it’s important to place APs away from these devices and use shielded cabling to minimize interference.

A passive site survey listens to existing RF activity and interference without sending any data, which helps in identifying interference sources without affecting the network.

Adding an AP in the dead zone will provide coverage to that area, ensuring there are no gaps in the wireless network.

Proper VLAN and subnet configuration is crucial for segregating wireless traffic and ensuring smooth integration of wireless controllers with the wired network.

CAPWAP (Control and Provisioning of Wireless Access Points) is the protocol used to control and manage APs from the wireless controller.

Enabling PoE on switch ports provides power to the APs through the Ethernet cable, simplifying deployment and reducing the need for separate power sources.

LAG combines multiple network links into a single logical link, providing load balancing and redundancy, which enhances network reliability and performance.

Configuring VLANs on the switches ensures proper segmentation of traffic, which is critical for managing and securing the network.

Mobility groups help in managing client handoffs between APs, allowing for seamless roaming and continuous connectivity.

802.11r fast roaming reduces the time required for clients to transition between APs, minimizing disconnections during movement.

An anchor controller is typically used to manage and secure guest traffic, isolating it from the internal network.

Fast roaming (802.11r) ensures that clients can transition between APs quickly and seamlessly, maintaining connectivity.

Mobility groups and fast roaming ensure that employees can move across the campus without experiencing disconnections, providing a seamless user experience.

N+1 redundancy provides an additional controller that can take over in case the primary controller fails, ensuring high availability.

SSO ensures that in case of a controller failure, a secondary controller can take over with minimal downtime, maintaining network reliability.

Load balancing helps distribute client connections evenly across APs, preventing any single AP from becoming overloaded and improving overall performance.

FlexConnect allows an AP to continue providing services to clients even if the connection to the primary controller is lost, ensuring continuous operation.

Redundant controllers with SSO ensure that if one controller fails, the other can seamlessly take over, minimizing disruption to the network.

What is the primary benefit of using 802.11ac Wave 2 over 802.11n in a wireless network?

MU-MIMO allows multiple devices to communicate with an AP simultaneously, significantly improving performance in high-density environments.

RRM optimizes the RF environment by dynamically adjusting channel assignments and power levels to reduce interference and improve performance.

Directional antennas focus the RF signal in a specific direction, which can help reduce interference and increase the signal strength in targeted areas.

Manually adjusting the channels to ensure minimal overlap helps reduce co-channel interference, improving overall connectivity and performance.

WPA3 offers enhanced security features, including stronger encryption and protection against brute-force attacks, providing a more secure wireless network.

A staggered or honeycomb layout ensures even coverage and minimal interference, providing optimal performance in a large open-plan office.

Load balancing distributes client connections evenly across multiple APs, preventing any single AP from becoming overloaded and ensuring better overall performance.

Staggering the AP placement vertically helps ensure even coverage and minimizes interference between floors in a multi-story building.

Sector antennas are ideal for outdoor environments with high user density, as they provide focused coverage over specific areas, reducing interference and enhancing performance.
