Configuration monitoring and management tools (often part of network management systems) maintain version-controlled records of device configurations, track changes, and log who made them. This provides accountability and supports compliance audits.

A. Network access control (NAC) manages endpoint access policies but does not track device config changes.

C. Zero Trust is a security framework requiring strict identity verification, not a configuration tracking tool.

D. Syslog collects system logs, but without a config monitoring system, it does not directly compare documentation to device state.

Comprehensive and Detailed Explanation (aligned to N10-009):

Multimode fiber uses multiple paths (modes) of light that bounce off the cladding to travel through the fiber. This is effective for shorter distances but more prone to dispersion.

A. Twinaxial is copper, not fiber.

B. Coaxial carries electrical signals, not light.

C. Single-mode fiber uses a single light path directly through the core without bouncing.

A rogue DHCP server occurs when an unauthorized or misconfigured DHCP server assigns incorrect IP addresses, default gateways, or DNS settings to clients.

•In this scenario:

•The user can ping the gateway, meaning local network communication is working.

•However, they cannot access network resources, which suggests incorrect IP configuration (likely due to a rogue DHCP server assigning the wrong gateway or DNS).

•Why not the other options?

•VLAN hopping (A): This is an attack that exploits VLAN configurations to gain access to unauthorized VLANs. It would not typically cause multiple users to lose network access.

•Distributed DoS (C): A DDoS attack floods a network or service with traffic, but this issue is more likely misconfigured IP settings than an actual attack.

•Evil twin (D): This refers to a fraudulent Wi-Fi network mimicking a legitimate one. Since the users are on a wired network (ipconfig output checked), this is not applicable.

Increasing the MTU (Maximum Transmission Unit) size allows larger frames to be transmitted, reducing overhead and improving throughput — especially for large file transfers like backups.

A. QoS prioritizes traffic but doesn’t reduce backup times directly.

B. SDN is a network management model, not a parameter change.

D. VXLAN encapsulates VLANs, not relevant to backup speeds.

E. TTL is for packet lifetime, not throughput.
