CompTIA Updated N10-009 Exam Questions and Answers by zach

A content filter blocks access to specific websites based on category, URL, or keywords. This is the best solution to restrict gambling websites.

Breakdown of Options:

A. ACLs – Control network access, not specific web content.

B. Content filter – ✅ Correct answer. Used to block access to unwanted websites.

C. Port security – Prevents unauthorized device connections, not web traffic filtering.

D. Screened subnet – A DMZ isolates public-facing servers, not user restrictions.

An SVI (Switched Virtual Interface) is a logical interface on a Layer 3-capable switch used to route traffic between VLANs. This is particularly useful in environments where voice and data traffic need to be separated, as each type of traffic can be assigned to different VLANs and routed accordingly.

SVI (Switched Virtual Interface): A virtual interface created on a switch for inter-VLAN routing.

VLAN Routing: Enables the routing of traffic between VLANs on a Layer 3 switch, allowing for logical separation of different types of traffic, such as voice and data.

Use Case: Commonly used in scenarios where efficient and segmented traffic management is required, such as in VoIP implementations.

MFA (Multi-Factor Authentication) requires factors from different categories:

Something you know → Password, PIN

Something you have → Smart card, hardware (hard) token

Something you are → Biometric

The correct second factor is a hard token.

A. PIN = something you know (same factor as password).

B. Favorite color = knowledge-based, same factor as password.

D. Mother’s maiden name = weak knowledge-based, same factor as password.

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.
