Power over Ethernet (PoE) delivers power to devices such as VoIP phones over the same cables used for data.
If the total power requirement of connected devices exceeds the PoE power budget of the switch or injector, some devices may not receive adequate power and could intermittently reboot. This issue would not affect the workstation, which is likely receiving power separately. References: CompTIA Network+ Exam Objectives and official study guides.

A Client-to-Site VPN allows a remote user to securely connect to a company's internal network, providing access as if they were physically on-site.

When high-bandwidth services like videoconferencing are introduced, two primary factors may degrade performance:
Incorrect QoS Settings (E):QoS (Quality of Service) is used to prioritize traffic. If not configured correctly, critical services like video may not get the necessary bandwidth and prioritization.
Network Congestion (F):Video services consume large amounts of data. If the network doesn't have sufficient bandwidth or is not segmented properly, congestion will slow down all services.
DNS misconfiguration (A) would affect name resolution, not bandwidth.
Malware (C) could degrade performance, but is not tied to the described scenario.
Outdated software (D) may affect performance in some cases, but not directly linked to network congestion in this case.
Inadequate network security (B) isn't likely to cause general slowness related to video traffic.
# So, the most likely culprits are E. Incorrect QoS settings and F. Network congestion.

WPA3-Enterprise provides strong security and supports authentication using domain identities through a RADIUS server and 802.1X authentication. This is the best choice for a corporate environment requiring user- based authentication.
WPA3-Enterprise Benefits:
Uses 802.1X with EAP (Extensible Authentication Protocol) to authenticate users via a directory service (e.g., Active Directory).
Eliminates shared passwords (PSK) for authentication.
Provides strong encryption and resistance to brute-force attacks.
Incorrect Options:
A). Enable MAC Security:
MAC filtering is not secure because MAC addresses can be spoofed.
B). Generate a PSK for Each User:
Pre-shared keys (PSK) are used in WPA-Personal, not in an enterprise setting.
Does not scale well in corporate environments.
C). Implement WPS:
Wi-Fi Protected Setup (WPS) is a vulnerable security method meant for home users.
Not suitable for enterprise authentication.

GDPR (General Data Protection Regulation)is alegal frameworkenforced by the European Union to protect personal data and privacy. Unlike internal organizational policies such as AUPs or codes of conduct, GDPR is alegislated regulation, and organizations must comply or face legal consequences.
