CompTIA Network+ Certification Exam Sample Questions (Q539-Q544):

NEW QUESTION # 539
A technician is trying to install a VolP phone, but the phone is not turning on. The technician checks the cable gong from the phone to the switch, and the cable is good. Which of the following actions IS needed for this phone to work?

  • A. Add a POE injector
  • B. Enable MDIX.
  • C. Reconfigure the port.
  • D. Use a crossover cable.

Answer: A

Explanation:
* A POE injector is a device that provides power and data over a single Ethernet cable to a POE device, such as a VoIP phone, a wireless access point, or a security camera12.
* A POE injector is needed when the switch or router that connects to the POE device does not support POE or does not have enough POE ports available12.
* A POE injector can be installed between the switch or router and the POE device, using two Ethernet cables: one from the switch or router to the injector, and another from the injector to the POE device12.
* A POE injector can supply up to 30W of power per port, depending on the POE standard it supports (802.3af or 802.3at)12.
* B. Enable MDIX is not a correct answer because MDIX is a feature that allows a switch or router to automatically detect the type of cable (straight-through or crossover) and adjust the pin assignments accordingly34.
* MDIX is not related to providing power to a POE device, and it is usually enabled by default on modern switches and routers34.
* C. Use a crossover cable is not a correct answer because a crossover cable is a type of Ethernet cable that swaps the transmit and receive pairs of wires, allowing two devices of the same type (such as two switches or two computers) to communicate directly56.
* A crossover cable is not needed to connect a VoIP phone to a switch or router, as they are different types of devices that use different pin assignments56.
* A crossover cable also does not provide power to a POE device, and it may not work with gigabit Ethernet or auto-MDIX devices56.
* D. Reconfigure the port is not a correct answer because reconfiguring the port on the switch or router that connects to the VoIP phone does not address the issue of providing power to the phone78.
* Reconfiguring the port may involve changing the speed, duplex, VLAN, or security settings, but none of these affect the power delivery to the POE device78.
* Reconfiguring the port may also cause network connectivity or performance issues if the settings are not compatible with the VoIP phone or the network78.

NEW QUESTION # 540
A client recently added 100 users who are using VMs. All users have since reported slow or unresponsive desktops. Reports show minimal network congestion, zero packet loss, and acceptable packet delay. Which of the following metrics will MOST accurately show the underlying performance issues? (Choose two.)

  • A. Jitter
  • B. Bandwidth
  • C. Latency
  • D. Temperature
  • E. CPU usage
  • F. Memory

Answer: E,F

Explanation:
The question asks about the metrics that will most accurately show the underlying performance issues of slow or unresponsive desktops for users who are using VMs (virtual machines).
VMs are software-based simulations of physical computers that run on a host system. They share the resources of the host system, such as CPU, memory, disk space, etc.
If the host system does not have enough resources to support the number of VMs running on it, the performance of the VMs will suffer. This is especially true if the VMs are running resource-intensive applications or tasks.
Therefore, the metrics that will most accurately show the underlying performance issues are CPU usage and memory. These metrics indicate how much of the host system's resources are being consumed by the VMs and how much is available for other processes.
The other metrics are not relevant to the question, as they are related to the network performance, not the host system performance. They are:
Temperature: the measure of how hot the host system or its components are. High temperature can cause overheating and damage to the hardware, but it is not directly related to the performance of the VMs.
Bandwidth: the measure of how much data can be transferred over a network connection in a given time. Low bandwidth can cause network congestion and slow data transfer, but it is not directly related to the performance of the VMs.
Latency: the measure of how long it takes for a data packet to travel from one point to another on a network. High latency can cause delays and poor quality of service, but it is not directly related to the performance of the VMs.
Jitter: the measure of how much the latency varies over time on a network. High jitter can cause inconsistent and unpredictable network performance, but it is not directly related to the performance of the VMs.

NEW QUESTION # 541
A company is designing a SAN and would like to use STP as its medium for communication. Which of the following protocols would BEST suit me company's needs?

  • A. SFTP
  • B. FTP
  • C. iSCSI
  • D. Fibre Channel

Answer: D

Explanation:
A SAN also employs a series of protocols enabling software to communicate or prepare data for storage. The most common protocol is the Fibre Channel Protocol (FCP), which maps SCSI commands over FC technology. The iSCSI SANs will employ an iSCSI protocol that maps SCSI commands over TCP/IP.
STP (Spanning Tree Protocol) is a protocol used to prevent loops in Ethernet networks, and it is not a medium for communication in a storage area network (SAN). However, Fibre Channel is a protocol that is specifically designed for high-speed data transfer in SAN environments. It is a dedicated channel technology that provides high throughput and low latency, making it ideal for SANs. Therefore, Fibre Channel would be the best protocol for the company to use for its SAN. SFTP (Secure File Transfer Protocol), iSCSI (Internet Small Computer System Interface), and FTP (File Transfer Protocol) are protocols used for transferring files over a network and are not suitable for use in a SAN environment.


NEW QUESTION # 542
Which of the following copper wire standards utilizes four pairs of wires to achieve Gigabit Ethernet speeds?

  • A. 1000BASE-FX
  • B. 1000BASE-LR
  • C. 1000BASE-SX
  • D. 1000BASE-T

Answer: D

Explanation:
The correct answer is 1000BASE-T. This standard is part of the Ethernet technologies and uses four pairs of Category 5 or higher copper cables. It's designed to support networks at Gigabit Ethernet speeds up to 1000 Mbps (1 Gbps) over distances up to 100 meters. Unlike the other options listed, which pertain to fiber optic cable standards (1000BASE-FX, 1000BASE-LR, and 1000BASE-SX), 1000BASE-T is the only one utilizing copper wiring, making it the suitable choice for this question.


NEW QUESTION # 543
A network administrator needs to provide evidence to confirm that recent network outages were caused by increased traffic generated by a recently released application. Which of the following actions will BEST support the administrator's response?

  • A. Collect the router's NetFlow data.
  • B. Export the firewall traffic logs.
  • C. Generate a network baseline report for comparison.
  • D. Plot interface statistics for dropped packets.

Answer: B
