   Users are reporting poor wireless performance in some areas of an industrial plant. The wireless controller is measuring a low EIRP value compared to the recommendations noted on the most recent site survey. Which of the following should be verified or replaced for the EIRP value to meet the site survey's specifications? (Choose two.)

   • AAP transmit power
   • BChannel utilization
   • CSignal loss
   • DUpdate ARP tables
   • EAntenna gain
   • FAP association time

   Show answer

   Answer: AE

   Explanation

   Signal loss is a generic term, in the context of EIRP antenna gain makes more sense: "Effective Isotropic Radiated Power (EIRP) is calculated as the sum of transmit power, antenna cable/connector loss, and antenna gain."

3. Question 393 · 871 in bank

   A network technician is hired to review all the devices within a network and make recommendations to improve network efficiency. Which of the following should the technician do FIRST before reviewing and making any recommendations?

   • ACapture a network baseline.
   • BPerform an environmental review.
   • CRead the network logs.
   • DRun a bandwidth test.

   Show answer

   Answer: A

   Explanation

   A. Capture a network baseline. Capturing a network baseline is the first step a network technician should take before reviewing and making any recommendations. A baseline helps to establish a starting point to measure network performance, identify performance issues, and track the effectiveness of any changes that are made to the network.

4. Question 394 · 871 in bank

   A company has multiple offices around the world. The computer rooms in some office locations are too warm. Dedicated sensors are in each room, but the process of checking each sensor takes a long time. Which of the following options can the company put in place to automate temperature readings with internal resources?

   • AImplement NetFlow.
   • BHire a programmer to write a script to perform the checks.
   • CUtilize ping to measure the response.
   • DUse SNMP with an existing collector server.

   Show answer

   Answer: D

   Explanation

   D. Use SNMP with an existing collector server. SNMP (Simple Network Management Protocol) is a protocol used for managing and monitoring network devices. It can be used to monitor and collect data from sensors in a network, including temperature sensors. By using an existing SNMP collector server, the company can automate the process of checking temperature readings from multiple sensors in different locations. This can help the company to identify the rooms that are too warm quickly and efficiently, without the need for manual checks.

5. Question 395 · 871 in bank

   Which of the following architectures reduces network latency by enforcing a limit on the number of switching devices on the frame's path between any internal hosts?

   • ASpine and leaf
   • BSoftware-defined network
   • CThree-tiered
   • DCollapsed core

   Show answer

   Answer: A

   Explanation

   A. Spine and Leaf Architecture The spine-leaf architecture consists of only two layers of switches spine and leaf switches. The spine layer consists of switches that perform routing and work as the core of the network. The leaf layer involves access switches that connect to servers, storage devices, and other end-users. This structure helps data center networks reduce hop count and reduce network latency.

6. Question 396 · 871 in bank

   A network administrator is decommissioning a server. Which of the following will the network administrator MOST likely consult?

   • AOnboarding and offboarding policies
   • BBusiness continuity plan
   • CPassword requirements
   • DChange management documentation

   Show answer

   Answer: D

   Explanation

   If the server would be a staff member, A would be correct. As this is about an IT appliance, we are talking about change management here.

7. Question 397 · 871 in bank

   A technician is investigating an issue with connectivity at customer's location. The technician confirms that users can access resources locally but not over the internet. The technician theorizes that the local router has failed and investigates further. The technician’s testing results show that the router is functional; however, users still are unable to reach resources on the internet. Which of the following describes what the technician should do NEXT?

   • ADocument the lessons learned.
   • BEscalate the issue.
   • CIdentify the symptoms.
   • DQuestion users for additional information.

   Show answer

   Answer: B

   Explanation

   Among the options given, B is indeed the one conforming to CompTIA's methodology. C and D should have been done exhaustively in the first place. A comes last after a solution has been shown to work.

8. Question 398 · 871 in bank

   On a network with redundant switches, a network administrator replaced one of the switches but was unable to get a connection with another switch. Which of the following should the administrator check after successfully testing the cable that was wired for TIA/EIA-568A on both ends?

   • AIf MDIX is enabled on the new switch
   • BIf PoE is enabled
   • CIf a plenum cable is being used
   • DIf STP is disabled on the switches

   Show answer

   Answer: A

   Explanation

   As no cross-over cable is being used, auto-MDIX needs to be enabled. No information on redundant routes has been provided to suggest that STP should be active.

9. Question 399 · 871 in bank

   Which of the following would MOST likely be used to review previous upgrades to a system?

   • ABusiness continuity plan
   • BChange management
   • CSystem life cycle
   • DStandard operating procedures

   Show answer

   Answer: B

   Explanation

   Per CertMaster's own N10-008 book, it explains that the change-management process includes Request for Change (RFC) documentation—resources that record why and when a change, such as an upgrade, was made. None of the other options would provide documentation for PREVIOUS changes to a system. Standard operating procedures might document work instructions for handling previously encountered incidents, but not for systemic changes like upgrades.

10. Question 400 · 871 in bank

    The lack of a formal process to grant network permissions to different profiles of employees and contractors is leading to an increasing number of security incidents. Non-uniform and overly permissive network accesses are being granted. Which of the following would be the MOST appropriate method to improve the security of the environment?

    • AChange the default permissions to implicit deny.
    • BConfigure uniform ACLs to employees and NAC for contractors.
    • CDeploy an RDP server to centralize the access to the network.
    • DImplement role-based access control.

    Show answer

    Answer: D

    Explanation

    The MOST appropriate method to improve the security of the environment, given the described situation, would be to implement role-based access control. Role-based access control (RBAC) is a method that assigns permissions to users based on their role in the organization. This method helps ensure that users only have the permissions they need to perform their job duties, and no more. By implementing RBAC, the organization can enforce a more uniform and controlled access to the network, reducing the risk of security incidents caused by overly permissive network accesses. The other options may help to some extent, but they do not address the underlying problem of non-uniform and overly permissive network accesses being granted.
