LDAP is commonly used for centralized user authentication and directory services, allowing systems and applications to authenticate users against a directory such as Active Directory.

If thecompany's SSID is not visiblein some areas while other networks are still visible, the most likely cause isinsufficient wireless coverage. The wireless signaldoes not reach those areas, meaning additional access points or signal boosters may be required.
Breakdown of Options:
* A. Interference or channel overlap- Would causeslow or unstable connections, but the SSID should still be visible.
* B. Insufficient wireless coverage-#Correct answer.If the SSID is not appearing, thesignal is too weakin that area.
* C. Roaming misconfiguration- Would causedevices to stay on weaker APsinstead of switching, but the SSID should still be visible.
* D. Client disassociation issues- This woulddisconnect users, but they shouldstill see the network.

Lockable cabinets are an effective physical security measure to prevent unauthorized access or modifications to hardware in an MDF (Main Distribution Frame) closet. By securing the equipment inside a locked cabinet, only authorized personnel can make changes to the hardware, which helps safeguard against tampering or unauthorized modifications.

Weak signal strength and low throughput in specific areas indicate coverage gaps, so adding additional access points improves signal coverage and capacity in those locations to resolve the connectivity issue.
