CompTIA Network+ Certification Exam Sample Questions (Q152-Q157):

NEW QUESTION # 152
Which of the following network cables involves bounding light off of protective cladding?

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

Answer: B

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 # 153
SIMULATION
A network technician needs to resolve some issues with a customer's SOHO network.
The customer reports that some of the devices are not connecting to the network, while others appear to work as intended.
INSTRUCTIONS
Troubleshoot all the network components and review the cable test results by Clicking on each device and cable.
Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem.

Cable Test Results:
Cable 1:

Cable 2:
Cable 3:
Cable 4:

Answer:

Explanation:
See the Explanation for detailed information on this simulation
Explanation:
(Note: Ips will be change on each simulation task, so we have given example answer for the understanding) To troubleshoot all the network components and review the cable test results, you can use the following steps:
Click on each device and cable to open its information window.
Review the information and identify any problems or errors that may affect the network connectivity or performance.
Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem.
Fill in the remediation form using the drop-down menus provided.
Here is an example of how to fill in the remediation form for PC1:
The component with a problem is PC1.
The problem is Incorrect IP address.
The solution is Change the IP address to 192.168.1.10.
You can use the same steps to fill in the remediation form for other components.
To enter commands in each device, you can use the following steps:
Click on the device to open its terminal window.
Enter the command ipconfig /all to display the IP configuration of the device, including its IP address, subnet mask, default gateway, and DNS servers.
Enter the command ping <IP address> to test the connectivity and reachability to another device on the network by sending and receiving echo packets. Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.
Enter the command tracert <IP address> to trace the route and measure the latency of packets from the device to another device on the network by sending and receiving packets with increasing TTL values. Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.
Here is an example of how to enter commands in PC1:
Click on PC1 to open its terminal window.
Enter the command ipconfig /all to display the IP configuration of PC1. You should see that PC1 has an incorrect IP address of 192.168.2.10, which belongs to VLAN 2 instead of VLAN 1.
Enter the command ping 192.168.1.1 to test the connectivity to Core Switch 1. You should see that PC1 is unable to ping Core Switch 1 because they are on different subnets.
Enter the command tracert 192.168.1.1 to trace the route to Core Switch 1. You should see that PC1 is unable to reach Core Switch 1 because there is no route between them.
You can use the same steps to enter commands in other devices, such as PC3, PC4, PC5, and Server 1.

NEW QUESTION # 154
A network administrator is developing a method of device monitoring with the following requirements:
Allows for explicit, by user, privilege management
Includes centralized logging of changes
Offers widely accessible remote management
Provides support of service accounts
Which of the following will most closely meet these requirements?

A. SNMP
B. SSO
C. API
D. SIEM

Answer: C

Explanation:
Comprehensive and Detailed Step-by-Step
API (Application Programming Interface) enables secure and granular access control, remote management, and logging, making it ideal for network monitoring.
SNMP (A) is mainly used for device monitoring but lacks centralized logging and user-based privilege control.
SIEM (C) is a security monitoring tool focused on log collection, not device management.
SSO (D) is related to authentication, not monitoring.
Reference: CompTIA Network+ N10-009 Official Documentation - Network Monitoring & Management Technologies.

NEW QUESTION # 155

Answer:

Explanation:
See explanation below.
Explanation:
On the first exhibit, the layout should be as follows

Exhibit 2 as follows
Access Point Name AP2

Exhibit 3 as follows
Access Point Name AP3

NEW QUESTION # 156
A company is purchasing a 40Gbps broadband connection service from an ISP. Which of the following should most likely be configured on the 10G switch to take advantage of the new service?

A. 802.1Q tagging
B. Link aggregation
C. Half duplex
D. Jumbo frames

Answer: B

Explanation:
Since the switch supports only 10Gbps per port, achieving 40Gbps throughput requires link aggregation (LACP), which combines multiple 10Gbps links into one logical interface for higher bandwidth.
Breakdown of Options:
A: 802.1Q tagging - VLAN tagging helps segment traffic but does not increase throughput.
B: Jumbo frames - Jumbo frames reduce overhead but do not increase bandwidth.
C: Half duplex - Half duplex restricts communication, reducing performance instead of improving it.
D: Link aggregation - Correct answer. LACP combines multiple 10Gbps links to provide a 40Gbps connection.
Reference:
