Content filtering blocks access to restricted or malicious websites. When a user attempts to visit a site that violates company policies, they are redirected to a restriction page.

This is a common security measure to prevent employees from accessing phishing or malware-infected sites.

Content filters work by scanning URLs, keywords, or categories and blocking inappropriate or harmful content.

Option A (DLP - Data Loss Prevention): Focuses on preventing sensitive data leaks rather than blocking web access.

Option B (Captive portal): Used mainly in public Wi-Fi to authenticate users before granting access, not to restrict sites.

Option D (DNS sinkholing): Redirects malicious domain requests to a safe address but is not responsible for policy-based restrictions on general content.

802.1Q tagging, also known as VLAN tagging, is used to identify VLANs on a trunk link between switches. This allows the switches to transfer data for multiple VLANs (or networks) over a single physical connection. This method ensures that traffic from different VLANs is properly separated and managed across the network.References: CompTIA Network+ study materials.

BGP (Border Gateway Protocol)is theonly dynamic routing protocol used across the internet. It's classified as an Exterior Gateway Protocol (EGP), responsible for routing between different autonomous systems (ASes).

A. EIGRPandD. OSPFare Interior Gateway Protocols (IGPs), used within organizations.

C. RIPis an outdated IGP with limited use, unsuitable for internet-scale routing.

If the IP phone works but the workstation doesn't, it indicates that theVoice VLAN is functioningcorrectly, but theData VLAN (C)is either misconfigured or missing. The workstation typically connects through the phone, which tags voice and data traffic separately usingVLANs.

A. Voice VLANis for the IP phone, which is already working.

B. Native VLANis for untagged traffic on trunk ports, but doesn’t control access directly.

D. Trunk portis more relevant to switch interconnections than individual workstation ports.
