CompTIA Network+ Certification Exam Sample Questions (Q100-Q105):

NEW QUESTION # 100
An administrator is configuring a switch that will be placed in an area of the office that is accessible to customers. Which of the following is the best way for the administrator to mitigate unknown devices from connecting to the network?

A. SSE
B. ACL
C. Perimeter network
D. 802.1x

Answer: D

Explanation:
802.1x is a network access control protocol that provides an authentication mechanism to devices trying to connect to a LAN or WLAN. This ensures that only authorized devices can access the network, making it ideal for mitigating the risk of unknown devices connecting to the network, especially in accessible areas.
802.1x Authentication: Requires devices to authenticate using credentials (e.g., username and password, certificates) before gaining network access.
Access Control: Prevents unauthorized devices from connecting to the network, enhancing security in public or semi-public areas.
Implementation: Typically used in conjunction with a RADIUS server to manage authentication requests.
Network Reference:
CompTIA Network+ N10-007 Official Certification Guide: Covers 802.1x and its role in network security.
Cisco Networking Academy: Provides training on implementing 802.1x for secure network access control.
Network+ Certification All-in-One Exam Guide: Explains the benefits and configuration of 802.1x authentication in securing network access.

NEW QUESTION # 101
Which of the following must be implemented to securely connect a company's headquarters with a branch location?

A. Split-tunnel VPN
B. Full-tunnel VPN
C. Clientless VPN
D. Site-to-site VPN

Answer: D

Explanation:
Site-to-Site VPN: A site-to-site VPN is used to securely connect two networks, such as a company's headquarters and a branch location, over the internet. This type of VPN creates a secure tunnel for data transmission, ensuring confidentiality and integrity.
Split-tunnel VPN (A): Allows some traffic to bypass the VPN tunnel, which may not secure all communications.
Clientless VPN (B): Used for individual users to access the network without VPN client software.
Full-tunnel VPN (C): Typically used for individual user traffic rather than connecting two networks.
Reference: CompTIA Network+ Official Study Guide, Domain 1.3 (Secure Network Connections).

NEW QUESTION # 102
A research facility is expecting to see an exponential increase in global network traffic in the near future. The offices are equipped with 2.5Gbps fiber connections from the ISP, but the facility is currently only utilizing
1Gbps connections. Which of the following would need to be configured in order to use the ISP's connection speed?

A. Link aggregation
B. Port duplex
C. 802.1Q tagging
D. Network address translation

Answer: A

NEW QUESTION # 103
Which of the following network cables involves bounding light off of protective cladding?

A. Multimode
B. Single-mode
C. Twinaxial
D. Coaxial

Answer: A

Explanation:
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.

NEW QUESTION # 104
A network administrator changed an external DNS to point customers to a new server. Which of the following tools should the administrator use to test the new server's configuration?

A. nslookup
B. ping
C. tcpdump
D. tracert

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step
nslookup allows querying DNS records to verify if the new server is correctly resolving domain names.
ping (A) tests basic connectivity, not DNS configuration.
tracert (B) shows network path latency but doesn't test DNS.
tcpdump (C) captures packets but isn't ideal for DNS verification.
