NEW QUESTION 1

A technician is troubleshooting servers with high CPU usage. While trying to connect, the technician needs to open a port for remote access. Which of the following ports should the
technician open?

• A. 443
• B. 3321
• C. 8080
• D. 5900

Answer: D

Explanation:
Port 5900 is the default port used by Virtual Network Computing (VNC), a graphical desktop-sharing system that allows remote access to another computer’s screen, keyboard and mouse1. VNC is one of the tools that can be used for remote troubleshooting of servers with high CPU usage, as it enables the technician to see the server’s desktop and perform actions on it. Port 5900 is also one of the ports listed in the CompTIA Network+ N10-008 exam objectives under the section "1.4 Given a scenario, use appropriate software tools to troubleshoot connectivity issues"2.
The other ports are not commonly used for remote access. Port 443 is used for Hypertext Transfer Protocol Secure (HTTPS), a secure version of HTTP that encrypts the communication between a web browser and a web server3. Port 3321 is used for Telepathy Broker Service, a service that provides communication between applications and telephony devices4. Port 8080 is used for HTTP Alternate, an alternative port for HTTP that is often used by web servers for testing or proxy purposes5.

NEW QUESTION 15

Users are reporting performance issues when attempting to access the main fileshare server. Which of the following steps should a network administrator perform next based on the network troubleshooting methodology?

• A. Implement a fix to resolve the connectivity issues.
• B. Determine if anything has changed.
• C. Establish a theory of probable cause.
• D. Document all findings, actions, and lessons learned.

Answer: B

Explanation:
According to the network troubleshooting methodology, the first step is to identify the problem and gather information about the current state of the network using the network troubleshooting tools that are available1. The next step is to determine if anything has changed in the network configuration, environment, or usage that could have caused or contributed to the performance issues1. This step helps to narrow down the possible causes and eliminate irrelevant factors. For example, the network administrator could check if there were any recent updates, patches, or modifications to the fileshare server or the network devices that connect to it. They could also check if there was an increase in network traffic or demand for the fileshare server resources2.
The other options are not correct because they are not the next steps in the network troubleshooting methodology. Implementing a fix to resolve the connectivity issues (A) is premature without determining the root cause of the problem. Establishing a theory of probable cause © is a later step that requires testing and verification. Documenting all findings, actions, and lessons learned (D) is the final step that should be done after resolving the problem and restoring normal network operations1.
