Question 1:
Which of the following steps in the troubleshooting methodology includes checking logs for recent changes?
A. Identify the problem.
B. Document the findings and outcomes.
C. Test the theory to determine cause.
D. Establish a plan of action.
Correct Answer: A

Question 2:
A customer recently moved into a new office and notices that some wall plates are not working and are not properly labeled
Which of the following tools would be best to identify the proper wiring in the IDF?
A. Toner and probe
B. Cable tester
C. Visual fault locator
D. Network tap
Correct Answer: A
A toner and probe tool, also known as a tone generator and probe, is used to trace and identify individual cables within a bundle or to locate the termination points of cables in wiring closets and patch panels.
It generates a tone that can be picked up by the probe, helping technicians quickly and accurately identify and label wall plates and wiring.
This is the best tool for identifying proper wiring in the Intermediate Distribution Frame (IDF). References: CompTIA Network+ Exam Objectives and official study guides.
Question 3:
Which of the following steps of the troubleshooting methodology should a technician take to confirm a theory?
A. Duplicate the problem.
B. Identify the symptoms.
C. Gather information.
D. Determine any changes.
Correct Answer: A

Question 4:
An organization wants to ensure that incoming emails were sent from a trusted source. Which of the following DNS records is used to verify the source?
A. TXT
B. AAAA
C. CNAME
D. MX
Correct Answer: A
A TXT record can be used to store SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) information, which help verify that an email has been sent from a trusted source.
Question 5:
A user\’s VoIP phone and workstation are connected through an inline cable. The user reports that the VoIP phone intermittently reboots, but the workstation is not having any network-related issues
Which of the following is the most likely cause?
A. The PoE power budget is exceeded.
B. Port security is violated.
C. The signal is degraded
D. The Ethernet cable is not working
Correct Answer: A
Power over Ethernet (PoE) delivers power to devices such as VoIP phones over the same cables used for data.
If the total power requirement of connected devices exceeds the PoE power budget of the switch or injector, some devices may not receive adequate power and could intermittently reboot.
This issue would not affect the workstation, which is likely receiving power separately. References: CompTIA Network+ Exam Objectives and official study guides.
Question 6:
Which of the following security methods uses physical characteristics of a person to authorize access to a location?
A. Access control vestibule
B. Palm scanner
C. PIN pad
D. Digital card reader
E. Photo ID
Correct Answer: B
A palm scanner is a security method that uses physical characteristics of a person, specifically the unique features of their palm or hand, to authorize access to a location. This biometric method is based on the individual\’s palm print, which is unique to each person.
Question 7:
Which of the following protocols provides remote access utilizing port 22?
A. SSH
B. Telnet
C. TLS
D. RDP
Correct Answer: A
SSH (Secure Shell) is a protocol used to securely connect to a remote server/system over a network. It operates on port 22 and provides encrypted communication, unlike Telnet which operates on port 23 and is not secure. TLS is used for
securing HTTP connections (HTTPS) and operates on ports like 443, while RDP (Remote Desktop Protocol) is used for remote desktop connections and operates on port 3389.
Reference:
The CompTIA Network+ materials and tutorials cover SSH as the standard protocol for secure remote access, highlighting its operation on port 22.
Question 8:
A company is designing a new complex. The primary and alternate data centers will be in separate buildings 6.2mi (10km) apart and will be connected via fiber. Which of the following types of SFP is the best choice?
A. 10GBASE-SR
B. 10000BASE-LX
C. 10GBASE-LR
D. 1000BASE-SX
Correct Answer: C
Question 9:
Which of the following attacks can cause users who are attempting to access a company website to be directed to an entirely different website?
A. DNS poisoning
B. Denial-of-service
C. Social engineering
D. ARP spoofing
Correct Answer: A
Network segmentation involves dividing a network into smaller segments or subnets. This is particularly important when integrating OT (Operational Technology) devices to ensure that these devices are isolated from other parts of the network.
Segmentation helps protect the OT devices from potential threats and minimizes the impact of any security incidents. It also helps manage traffic and improves overall network performance.

Question 10:
A network administrator performed upgrades on a server and installed a new NIC to improve performance. Following the upgrades, usera are unable to reach the server. Which of the following is the most likely reason.
A. The PoE power budget was exceeded.
B. TX/RX was transposed.
C. A port security violation occured.
D. An incorrect cable type was installed.
Correct Answer: D
When a network administrator installs a new Network Interface Card (NIC) and users are unable to reach the server, one of the common issues is the use of an incorrect cable type.
Network cables must match the specifications required by the NIC and the network infrastructure (e.g., Cat5e, Cat6 for Ethernet).
NIC Compatibility: The new NIC might require a specific type of cable to function properly. Using a cable not rated for the NIC\’s required speeds or capabilities can result
in connectivity issues.
Cable Standards: Different NICs and network devices might need different cabling standards (straight-through vs. crossover cables, or specific fiber optic types).
Connection Types: Ensuring that the cable connectors are appropriate for the NIC ports (e.g., RJ45 for Ethernet, LC connectors for fiber optics).

Question 13:
A technician is planning an equipement installation into a rack in a data center that practices hot aisle/cold aise ventilation. Which of the following directions should the equipement exhaust face when installed in the rack?
A. Sides
B. Top
C. Front
D. Rear
Correct Answer: D
In a data center that practices hot aisle/cold aisle ventilation, equipment should be installed so that the exhaust faces the rear of the rack. This setup ensures that hot air is expelled into the hot aisle, maintaining proper airflow and cooling efficiency.
Hot Aisle/Cold Aisle Configuration: Equipment intake should face the cold aisle where cool air is supplied, and exhaust should face the hot aisle where hot air is expelled. Cooling Efficiency: Proper orientation of equipment helps
maintain an efficient cooling environment by segregating hot and cold air, preventing overheating and improving energy efficiency.

Question 14:
A network administrator is planning to implement device monitoring to enhance network visibility. The security that the solution provies authentication and encryption. Which of the following meets these requirements?
A. SIEM
B. Syslog
C. NetFlow
D. SNMPv3
Correct Answer: D
SNMPv3 (Simple Network Management Protocol version 3) provides device monitoring with authentication and encryption.
This enhances network visibility and security by ensuring that monitoring data is securely transmitted and access to network devices is authenticated.
Authentication: SNMPv3 includes robust mechanisms for authenticating users accessing network devices.
Encryption: It provides encryption to protect the integrity and confidentiality of the data being transmitted.
Network Management: SNMPv3 allows for detailed monitoring and management of network devices, ensuring better control and security.
Network References:

Question 15:
A network technician needs to use an RFC1918 IP space for a new office that only has a single public IP address. Which of the following subnets should the technician use for the LAN?
A. 10.10.10.0/24
B. 127.16.10.0/24
C. 174.16.10.0/24
D. 198.18.10.0/24
Correct Answer: A
The RFC1918 IP space is a set of private IP addresses that are not routable on the public Internet and can be used for internal networks.
The RFC1918 IP space consists of three ranges: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/161 Out of the four options, only A. 10.10.10.0/24 belongs to one of these ranges, specifically the 10.0.0.0/8 range.
Therefore, the technician should use this subnet for the LAN. References1: https://en.wikipedia.org/wiki/Private_network
