In the CompTIA Network+ (N10-009) troubleshooting methodology, the step that follows verifying full system functionality (confirming the issue is resolved and validating with the user/requirements) is documenting findings, actions, and outcomes. Documentation is a required closing step because it captures what the original symptoms were, what troubleshooting steps were performed, what root cause was identified (if found), what remediation was applied, and what validation confirmed success. This record supports operational continuity by enabling faster resolution if the issue recurs, improving knowledge transfer across teams, and meeting organizational change-control or compliance requirements.
The other options fall in different parts of the methodology. Attempting to replicate the problem is typically performed earlier-after identifying symptoms and before or during isolation-to confirm the issue and help narrow scope. Implementing the plan occurs before verification; you implement the selected solution or escalation plan and then test/verify. Escalating the issue occurs when the technician lacks access, expertise, time, or evidence to proceed, and it can happen during troubleshooting-but it is not the standard step that comes after verifying resolution.

To implement data loss prevention (DLP) and restrict user access to social media platforms and personal cloud storage, the company should deploy content filtering. Content filtering examines the data being transmitted over the network and can block specific types of content or websites based on predefined policies. This type of filtering is effective in preventing access to specific web services and ensuring that sensitive information does not leave the network through unauthorized channels. Port, DNS, and MAC filtering serve different purposes and are not as effective for DLP in this context.

A jump box is a hardened system that provides secure access to isolated or sensitive devices on a separate network.
Breakdown of Options:
A). Jump box - # Correct answer. Acts as a middle point for secure remote access.
B). API gateway - Used for managing API calls, not remote access to isolated devices.
C). Secure Shell (SSH) - Requires direct connectivity, which may not be available for an isolated device.
D). Clientless VPN - Allows web-based VPN access, but does not guarantee access to isolated devices.

Shortening the DHCP lease time allows IP addresses assigned to transient guest users to return to the available pool more quickly, reducing the chance that the address pool will be exhausted.

802.1X is a port-based Network Access Control (NAC) method that enforces authentication before allowing access to the network. It uses a RADIUS server for identity verification and policy enforcement, ensuring only authorized users/devices gain access.
* A. Standard ACL filters traffic by IP, not identity.
* B. MAC filtering controls devices by hardware address but can be spoofed.
* D. SSO (Single Sign-On) provides user convenience across services, not network-level access control.
