   A network administrator wants to install new VoIP switches in small network closet but is concerned about the current heat level of the room. Which of the following should the administrator take into consideration before installing the new equipment?

   • AThe power load of the switches
   • BThe humidity in the room
   • CThe fire suppression system
   • DThe direction of airflow within the switches

   Show answer

   Answer: D

   Explanation

   Direction of airflow is a thing and it's different between various switch makes and models. If you orient the switches properly to direct hot air going out in the most logical way you'll make the biggest impact on mitigating heat. You can't change the power levels in the switches, the only thing the tech can actually do that would help is be aware of airflow and control it as properly as possible.

   Which of the following is the next step to take after successfully testing a root cause theory?

   • ADetermine resolution steps.
   • BDuplicate the problem in a lab.
   • CPresent the theory for approval.
   • DImplement the solution to the problem.

   Show answer

   Answer: A

   Explanation

   According to CompTIA Network+ principles, the recommended next step after successfully testing a root cause theory is: A. Determine resolution steps. The sequence often involves identifying the root cause, testing theories to validate the cause, determining the steps needed to resolve the issue, and finally implementing the solution. So, after successfully testing a root cause theory, the next logical step is to determine the resolution steps before moving on to the implementation phase.

   A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?

   • AConfigure ACLs.
   • BImplement a captive portal.
   • CEnable port security.
   • DDisable unnecessary services.

   Show answer

   Answer: C

   Explanation

   C. Enable port security. Port security is a feature available on network switches that allows the administrator to control which devices are permitted to connect to individual switch ports. It enables the switch to limit and identify the MAC addresses allowed to access the network through specific switch ports. By configuring port security, the administrator can define and restrict the number of MAC addresses allowed on a port, specify which MAC addresses are permitted to access the port, and take actions (like shutting down the port) when unauthorized devices attempt to connect. This helps to prevent unauthorized devices from gaining network access via that switch port.

   Which of the following does OSPF use to communicate routing updates?

   • AUnicast
   • BAnycast
   • CMulticast
   • DBroadcast

   Show answer

   Answer: C

   Explanation

   C. Multicast. OSPF uses multicast addresses to communicate routing updates. It sends its updates using the multicast address 224.0.0.5, which is used for all OSPF routers, and the multicast address 224.0.0.6, used for all OSPF designated routers. This method is efficient in terms of network bandwidth, as it allows OSPF routers to receive updates without the need for sending individual updates to each router (unicast) or broadcasting to all devices in the network (broadcast).

   A user notifies a network administrator about losing access to a remote file server. The network administrator is able to ping the server and verifies the current firewall rules do not block access to the network fileshare. Which of the following tools would help identify which ports are open on the remote file server?

   • Adig
   • Bnmap
   • Ctracert
   • Dnslookup

   Show answer

   Answer: B

   Explanation

   B. nmap To identify which ports are open on the remote file server, the network administrator can use the "nmap" tool. Nmap is a network scanning tool that can be used to discover open ports, services running on those ports, and other information about the target system. The other options: A. dig: This is a DNS (Domain Name System) query tool used for looking up domain information. It is not designed for identifying open ports on a server. C. tracert: This is a tool used for tracing the route that packets take to reach a destination. It does not provide information about open ports on a server. D. nslookup: This is another DNS-related tool used for querying DNS servers for domain name information. Like "dig," it is not designed for identifying open ports on a server.

6. Question 626 · 871 in bank

   A security team would like to use a system in an isolated network to record the actions of potential attackers. Which of the following solutions is the security team implementing?

   • APerimeter network
   • BHoneypot
   • CZero trust infrastructure
   • DNetwork segmentation

   Show answer

   Answer: B

   Explanation

   B. Honeypot. A honeypot is a security mechanism set up to act as a trap, simulating vulnerabilities and services that might attract attackers. Its primary purpose is to be probed, attacked, or compromised in order to study the attackers' behavior, techniques, and methods without affecting the actual production systems. The isolated network containing the honeypot is separate from the main network and is designed to monitor and log any unauthorized access attempts or malicious activities. It allows the security team to study the attackers' tactics, tools, and motives while preventing them from reaching critical systems or causing damage to the actual infrastructure.

   An organization has a factory automation solution that requires accurate timing between devices. Which of the following should the network administrator implement?

   • APTP
   • BNTP
   • CNTS
   • DDoT

   Show answer

   Answer: B

   Explanation

   If you're referring to CompTIA study materials, CompTIA does cover foundational networking concepts and might touch on time synchronization in a broader context. However, CompTIA A+, Network+, and Security+ books may not delve deeply into specific protocols like PTP (Precision Time Protocol) for accurate time synchronization. In the context of CompTIA materials, you'd generally expect to see: B. NTP (Network Time Protocol) as the recognized protocol for time synchronization. NTP is widely used for syncing time across networks and devices. So, if you're preparing for a CompTIA exam and basing your answer solely on the material provided by CompTIA, then the answer would likely lean towards: B. NTP Always refer to the specific study material and objectives outlined by CompTIA for the most accurate preparation.

8. Question 628 · 871 in bank

   A network administrator needs to set up a file server to allow user access. The organization uses DHCP to assign IP addresses. Which of the following is the best solution for the administrator to set up?

   • AA separate scope for the file server using a /32 subnet
   • BA reservation for the server based on the MAC address
   • CA static IP address within the DHCP IP range
   • DA SLAAC for the server

   Show answer

   Answer: B

   Explanation

   B. A reservation for the server based on the MAC address. Assigning a DHCP reservation for the server based on its MAC address ensures that the file server will consistently receive the same IP address every time it connects to the network. This approach provides the advantages of DHCP (automatic assignment of IP addresses) while also guaranteeing a specific and consistent IP address for the file server, making it easy for users to access it reliably.

9. Question 629 · 871 in bank

   A fiber link connecting two campus networks is broken. Which of the following tools should an engineer use to detect the exact break point of the fiber link?

   • AOTDR
   • BTone generator
   • CFusion splicer
   • DCable tester
   • EPoE injector

   Show answer

   Answer: A

   Explanation

   Answer is correct: An Optical Time Domain Reflectometer (OTDR) is a device that tests the integrity of a fiber cable and is used for the building, certifying, maintaining, and troubleshooting fiber optic systems. Fusion Splicing is a preferred way to join two fibers together by using heat. Whether the fiber was broken or not long enough, a fusion splicer will make your job easier. You would do this after finding where the break is.

    Which of the following ports is a secure protocol?

    • A20
    • B23
    • C443
    • D445

    Show answer

    Answer: C

    Explanation

    C. 443 Port 443 is associated with the HTTPS (Hypertext Transfer Protocol Secure) protocol, which is a secure version of HTTP. HTTPS is commonly used for secure communication over a computer network, such as the internet. It encrypts the data exchanged between a user's web browser and a web server, providing a secure and private connection.
