質問 # 176
A user connects to a corporate VPN via a web browser and is able to use TLS to access the internal financial system to input a time card. Which of the following best describes how the VPN is being used?
正解：C
解説：
The scenario describes a user connecting to a corporate VPN via a web browser using TLS to access an internal system. This setup is best described as a "clientless" VPN. Clientless VPNs do not require a VPN client to be installed on the user's device; instead, they rely on a standard web browser to establish the connection. This method is particularly useful for providing secure, remote access to applications through a web interface without the need for additional software installations.

質問 # 177
Which of the following network cables involves bounding light off of protective cladding?
正解：C
解説：
Multimode fiber optic cables involve the transmission of light signals that bounce off the core's cladding as they travel down the fiber. This characteristic differentiates it from single-mode fiber, where the light travels directly down the fiber without reflecting off the cladding.
Here are some detailed points about multimode fiber cables:
* Construction: Multimode fibers have a larger core diameter, typically 50 or 62.5 microns, compared to single-mode fibers, which have a core diameter of about 9 microns.
* Light Propagation: The larger core of multimode fiber allows multiple light modes to propagate. These modes travel at different angles, leading to reflections off the core-cladding boundary.
* Distance and Bandwidth: Due to modal dispersion, where different light modes arrive at the receiver at
* different times, multimode fibers are suited for shorter distance applications compared to single-mode fibers. Typical distances are up to 550 meters for 10 Gbps Ethernet using OM4 multimode fiber.
* Applications: Multimode fibers are commonly used in LANs (Local Area Networks), data centers, and for shorter distance data transmission due to their cost-effectiveness and ease of installation.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide, which covers fiber optic technologies, including the differences between multimode and single-mode fibers.
* Cisco Networking Academy: Provides training materials and reference guides on the properties of different fiber optic cables.
* Fiber Optic Association (FOA): A professional society dedicated to fiber optics, offering extensive information and certification on fiber optic technologies.
Multimode fibers are specifically designed for short-range communication with higher data rates and are typically used in environments like data centers, where high bandwidth over shorter distances is crucial. The reflections off the cladding, inherent to multimode fiber, facilitate this high-capacity communication.
質問 # 178
A customer purchases a new UTM device and wants the development team to integrate some of the device's data-reporting capabilities into the company's custom internal support software. Which of the following features should the development team use to obtain the device's data?
正解：C
解説：
An API (Application Programming Interface) is the best choice when a development team needs to integrate a device's reporting data directly into custom software. In Network+ (N10-009) objectives, network operations commonly include device management, monitoring, and automation, and APIs are a key method for programmatic access to operational data (often via REST/HTTPS with structured formats like JSON). This enables the internal support application to pull dashboards, health metrics, events, configuration details, and reporting outputs in a controlled, developer-friendly way.
SNMPv2c is primarily used for network monitoring and polling counters/alerts, but it is less secure (community strings) and is not as flexible for modern application integration as an API. A MIB is not a data- access "feature" by itself; it's the schema/definitions SNMP uses to describe managed objects. A SIEM is a separate security analytics platform that collects and correlates logs/events-useful for security operations, but not the direct interface a custom support tool would typically call to retrieve device reporting data.
質問 # 179
A client wants to increase overall security after a recent breach. Which of the following would be best to implement? (Select two.)
正解：B、E
解説：
To increase overall security after a recent breach, implementing least privilege network access and central policy management are effective strategies.
* Least Privilege Network Access: This principle ensures that users and devices are granted only the access necessary to perform their functions, minimizing the potential for unauthorized access or breaches. By limiting permissions, the risk of an attacker gaining access to critical parts of the network is reduced.
* Central Policy Management: Centralized management of security policies allows for consistent and streamlined implementation of security measures across the entire network. This helps in quickly responding to security incidents, ensuring compliance with security protocols, and reducing the chances of misconfigurations.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide: Discusses network security principles, including least privilege and policy management.
* Cisco Networking Academy: Provides training on implementing security policies and access controls.
* Network+ Certification All-in-One Exam Guide: Covers strategies for enhancing network security and managing policies effectively.
質問 # 180
A network technician is requesting a fiber patch cord with a connector that is round and twists to install. Which of the following is the proper name of this connector type?
正解：D
解説：
The ST (Straight Tip) connector uses a round, bayonet-style twist lock mechanism for installation.
