CompTIA Network+ Certification Exam Sample Questions (Q96-Q101):

NEW QUESTION # 96
Which of the following attacks involves creating a rogue access point with the same SSID as a legitimate wireless network to deceive users into connecting?

Answer: D

Explanation:
An evil twin attack sets up a rogue AP with the same SSID as a legitimate wireless network, tricking users into connecting. Once connected, the attacker can intercept traffic or harvest credentials.
* B. Describes ARP spoofing.
* C. Describes MAC spoofing.
* D. Describes on-path attacks, which may follow, but the evil twin method begins with SSID impersonation.
References (CompTIA Network+ N10-009):
* Domain: Network Security - Wireless threats, rogue APs, evil twin.


NEW QUESTION # 97
Which of the following is enforced through legislation?

Answer: A

Explanation:
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.
Reference:Section 4.1 - Basic Network Security Concepts - "GDPR and Compliance Regulations"


NEW QUESTION # 98
A network administrator is responding to a request to configure a new IP phone. Which of the following should the network administrator do to allow data and voice traffic to be properly prioritized?

Answer: B

Explanation:
To ensure voice and data traffic are properly prioritized for an IP phone, the administrator should modify (configure) QoS. In Network+ (N10-009), QoS is the primary mechanism used to prioritize latency-sensitive traffic such as VoIP. By classifying and marking voice frames/packets (often using DSCP/CoS values) and applying priority queuing, the network ensures voice traffic experiences minimal delay and jitter even when links are congested. This is essential for call quality because voice is highly sensitive to variation in delivery time and packet loss.
802.1Q tagging is important for VLAN separation (and many IP phone deployments use a voice VLAN), but VLAN tagging alone does not guarantee prioritization; it separates traffic, while QoS provides preferential treatment. Full duplex can reduce collisions on Ethernet links, but it does not implement traffic prioritization policies. Changing the native VLAN is a trunking/security configuration detail and not the correct action to prioritize voice versus data. In practice, networks often use both a voice VLAN (802.1Q) and QoS, but for the explicit requirement of prioritization, QoS is the correct answer.


NEW QUESTION # 99
Which of the following services runs on port 636?

Answer: A

Explanation:
LDAP over SSL (LDAPS) uses port 636 to provide secure, encrypted authentication for directory services.
Breakdown of Options:
A . SMTP (Simple Mail Transfer Protocol) - Uses port 25, not 636.
B . Syslog - Uses port 514 (UDP), not 636.
C . TFTP (Trivial File Transfer Protocol) - Uses port 69 (UDP), not 636.
D . LDAPS (Lightweight Directory Access Protocol Secure) - ✅ Correct answer. Uses port 636 for secure directory authentication.
Reference:
CompTIA Network+ (N10-009) Official Study Guide - Domain 3.1: Compare and contrast network protocols.
RFC 4511: Lightweight Directory Access Protocol (LDAP)


NEW QUESTION # 100
Which of the following is the best example of implementing role-based access control?

Answer: A

Explanation:
Role-based access control, or RBAC, assigns permissions according to a user's job role or responsibility within the organization. In this question, granting data center access only to server and network administrators is the best example because the permission is tied directly to the users' operational roles. Server administrators and network administrators typically require physical or logical access to data center infrastructure to perform maintenance, troubleshooting, configuration, and support tasks. This aligns with the CompTIA Network+ N10-009 security objectives related to authentication, authorization, and access control.
Option B is too broad because giving the entire IT department access to an application development server may violate least privilege. Not every IT employee needs that access. Option C describes multifactor authentication, which strengthens authentication but does not define authorization by role. Option D is closer to discretionary access control because the HR director is deciding who can access files. RBAC is centrally defined by roles, not by an individual data owner's discretion. Therefore, option A is the strongest RBAC example.
