Question #62
A network architect needs to create a wireless field network to provide reliable service to public safety vehicles.
Which of the following types of networks is the best solution?
- A . Mesh
- B . Ad hoc
- C . Point-to-point
- D . Infrastructure
Correct Answer: A
A
Explanation:
A mesh network is the best solution for providing reliable wireless service to public safety vehicles. In a mesh network, each node (vehicle) can connect to multiple other nodes, providing multiple paths for data to travel. This enhances reliability and redundancy, ensuring continuous connectivity even if one or more nodes fail. Mesh networks are highly resilient and are well-suited for dynamic and mobile environments such as public safety operations.

Question #63
Before using a guest network, an administrator requires users to accept the terms of use.
Which of the following is the best way to accomplish this goal?
- A . Pre-shared key
- B . Autonomous access point
- C . Captive portal
- D . WPA2 encryption
Correct Answer: C
C
Explanation:
A captive portal is a web page that users must view and interact with before being granted access to a network. It is commonly used in guest networks to enforce terms of use agreements. When a user connects to the network, they are redirected to this portal where they must accept the terms of use before proceeding. This method ensures that users are aware of and agree to the network’s policies, making it the best choice for this scenario.

Question #65
An organization has a security requirement that all network connections can be traced back to a user. A network administrator needs to identify a solution to implement on the wireless network.
Which of the following is the best solution?
- A . Implementing enterprise authentication
- B . Requiring the use of PSKs
- C . Configuring a captive portal for users
- D . Enforcing wired equivalent protection
Correct Answer: A
A
Explanation:
Enterprise authentication (such as WPA2-Enterprise) utilizes unique credentials for each user, typically integrating with an authentication server like RADIUS. This allows for tracking and logging user activity, ensuring that all connections can be traced back to individual users. PSKs (Pre-Shared Keys) are shared among users and do not provide individual accountability. Captive portals can identify users but are less secure than enterprise authentication, and Wired Equivalent Privacy (WEP) is outdated and not recommended for security purposes.
Reference: CompTIA Network+ materials highlight enterprise authentication methods as the preferred solution for secure and accountable wireless network access.

Question #66
A customer recently moved into a new office and notices that some wall plates are not working and are not properly labeled Which of the following tools would be best to identify the proper wiring in the IDF?
- A . Toner and probe
- B . Cable tester
- C . Visual fault locator
- D . Network tap
Correct Answer: A
A
Explanation:
A toner and probe tool, also known as a tone generator and probe, is used to trace and identify individual cables within a bundle or to locate the termination points of cables in wiring closets and patch panels. It generates a tone that can be picked up by the probe, helping technicians quickly and accurately identify and label wall plates and wiring. This is the best tool for identifying proper wiring in the Intermediate Distribution Frame (IDF).

Question #67
A network administrator needs to add 255 useable IP addresses to the network. A /24 is currently in use.
Which of the following prefixes would fulfill this need?
- A . /23
- B . /25
- C . /29
- D . /32
Correct Answer: A
A
Explanation:
A /23 subnet provides 512 total addresses, of which 510 are usable (subtracting 2 for network and broadcast addresses). This would satisfy the need for 255 additional addresses.

Question #69
Which of the following network devices converts wireless signals to electronic signals?
- A . Router
- B . Firewall
- C . Access point
- D . Load balancer
Correct Answer: C
C
Explanation:
Role of an Access Point (AP):
Wireless to Wired Conversion: An access point (AP) is a device that allows wireless devices to connect to a wired network using Wi-Fi. It converts wireless signals (radio waves) into electronic signals that can be understood by wired network devices.
Functionality:
Signal Conversion: The AP receives wireless signals from devices such as laptops, smartphones, and tablets, converts them into electronic signals, and transmits them over the wired network.
Connectivity: APs provide a bridge between wireless and wired segments of the network, enabling seamless communication.
Comparison with Other Devices:
Router: Directs traffic between different networks and may include built-in AP functionality but is not primarily responsible for converting wireless to electronic signals.
Firewall: Protects the network by controlling incoming and outgoing traffic based on security rules, not involved in signal conversion.
Load Balancer: Distributes network or application traffic across multiple servers to ensure reliability and performance, not involved in signal conversion.
Deployment:
APs are commonly used in environments where wireless connectivity is needed, such as offices, homes, and public spaces. They enhance mobility and provide flexible network access.

Question #70
Which of the following is the most likely benefit of installing server equipment in a rack?
- A . Simplified troubleshooting process
- B . Decreased power consumption
- C . Improved network performance
- D . Increased compute density
Correct Answer: D
D
Explanation:
Installing server equipment in a rack increases compute density by allowing multiple servers to be organized efficiently in a vertical configuration, saving space while housing more devices in a smaller footprint. This is critical for data centers and businesses with high hardware demands.
Simplified troubleshooting process (A): While racks can aid in organizing equipment, this is a secondary benefit, not the primary purpose.
Decreased power consumption (B): Rack installation does not directly reduce power usage; equipment power consumption remains the same.
Improved network performance (C): Racking servers does not inherently improve network performance; that depends on network configurations.
