CompTIA Network+ Certification Exam Sample Questions (Q237-Q242):

NEW QUESTION # 237
Which of the following are environmental factors that should be considered when installing equipment in a building? (Choose two).

  • A. Humidity control
  • B. Fire suppression system
  • C. UPS location
  • D. Power load
  • E. Proximity to nearest MDF
  • F. Floor construction type

Answer: A,B

Explanation:
When installing equipment in a building, environmental factors are critical to ensure the safety and longevity of the equipment. A fire suppression system is essential to protect the equipment from fire hazards. Humidity control is crucial to prevent moisture-related damage, such as corrosion and short circuits, which can adversely affect electronic components. Both factors are vital for maintaining an optimal environment for networking equipment.


NEW QUESTION # 238
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. Link aggregation
  • B. 802.1Q tagging
  • C. Jumbo frames
  • D. Half duplex

Answer: A

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.

NEW QUESTION # 239
Network administrators are using the Telnet protocol to administer network devices that are on the
192.168.1.0/24 subnet. Which of the following tools should the administrator use to best identify the devices?

  • A. nmap
  • B. telnet
  • C. dig
  • D. tracert

Answer: A

Explanation:
nmap(Network Mapper) is the best tool in this scenario. It can scan the 192.168.1.0/24 subnet to discoverlive hosts, open ports (like Telnet on port 23), and device types. It's ideal for mapping and auditing the network.
* A. digis a DNS lookup tool; not useful for identifying hosts on a subnet.
* C. tracertshows the path packets take to a destination, not for host discovery.
* D. telnetis the protocol being used, not a tool for scanning or identifying devices.
#Reference:
CompTIA Network+ N10-009 Official Objectives: 5.1 - Given a scenario, use the appropriate network troubleshooting tools.


NEW QUESTION # 240
A network engineer discoversnetwork trafficthat is sendingconfidential informationto anunauthorized and unknown destination. Which of the followingbest describesthe cause of this network traffic?

  • A. Darkware
  • B. Ransomware
  • C. Malware
  • D. Adware

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
Malwarerefers toany malicious softwarethat canexfiltrate confidential data, includingspyware, trojans, and rootkits. This fits the scenario whereunauthorized data transferis occurring.
Breakdown of Options:
* A. Adware- Displaysads, doesnot typically steal data.
* B. Ransomware- Encrypts filesbut does not exfiltrate data.
* C. Darkware-Not a real cybersecurity term.
* D. Malware-Correct answer.Malicious software is responsible for unauthorized data exfiltration.


NEW QUESTION # 241
Which of the following disaster recovery concepts is calculated by dividing the total hours of operation by the total number of units?

  • A. MTTR
  • B. RTO
  • C. MTBF
  • D. RPO

Answer: C

Explanation:
* Introduction to Disaster Recovery Concepts:
* Disaster recovery involves strategies and measures to ensure business continuity and data recovery in the event of a disaster.
* Mean Time Between Failures (MTBF):
* MTBF is a reliability metric used to predict the time between failures of a system during operation. It is calculated by dividing the total operational time by the number of failures.
* Formula:MTBF=Total Operational TimeNumber of Failurestext{MTBF} = frac{text{Total Operational Time}}{text{Number of Failures}}MTBF=Number of FailuresTotal Operational Time
* This metric helps in understanding the reliability and expected lifespan of systems and components.
* Example Calculation:
* If a server operates for 1000 hours and experiences 2 failures, the MTBF is:
MTBF=1000 hours2=500 hourstext{MTBF} = frac{1000 text{ hours}}{2} = 500 text{ hours}MTBF=21000 hours=500 hours
* Explanation of the Options:
* A. MTTR (Mean Time to Repair):The average time required to repair a system after a failure.
* B. MTBF (Mean Time Between Failures):The correct answer, representing the average time between failures.
* C. RPO (Recovery Point Objective):The maximum acceptable amount of data loss measured in time.
* D. RTO (Recovery Time Objective):The target time set for the recovery of IT and business activities after a disaster.
* Conclusion:
* MTBF is a crucial metric in disaster recovery and system reliability, helping organizations plan maintenance and predict system performance.
