CompTIA N10-008 Questions Answers

The authentication method that this setup describes is SSO (Single Sign-On). SSO is a technique that allows a user to log in once to a main web application and then access multiple other applications or services without having to re-enter credentials. SSO simplifies the user experience and reduces the number of passwords to remember and manage. References: CompTIA Network+ N10-008 Certification Study Guide, page 371; The Official CompTIA Network+ Student Guide (Exam N10-008), page 14-5.

• The address 127.0.0.1 is a special IP address that is used to refer to the local host or the computer itself12.
• This address is also known as the loopback address, because it loops back to the same device without going through any network devices12.
• A network technician can use this address to perform traffic diagnostic tests on a potentially faulty network card, by sending and receiving packets to and from the same device12.
• This way, the technician can check if the network card is functioning properly, without involving any external factors such as network congestion, firewall rules, or routing issues12.
• The address 10.10.10.10 (A) is a private IP address that is used for internal network communication, but it is not a loopback address12.
• The address 192.168.0.1 © is another private IP address that is often used as the default gateway for home routers, but it is also not a loopback address12.
• The address 255.255.255.0 (D) is a subnet mask that is used to define the network and host portions of an IP address, but it is not an IP address itself12. References:

 A split tunnel VPN solution would allow secure, remote access for sales staff to the CRM application without impacting videoconferencing traffic. A VPN stands for virtual private network, which is a secure connection between two or more devices over a public network, such as the internet. A VPN encrypts and authenticates the data, ensuring its confidentiality and integrity. A split tunnel VPN is a type of VPN that allows some traffic to go through the VPN tunnel, while other traffic goes directly to the internet. This can improve performance and bandwidth utilization by reducing unnecessary encryption and routing overhead. By using a split tunnel VPN, sales staff can access the CRM application that connects to a database server in the corporate data center through the VPN tunnel, while using online videoconferencing services through their local internet connection. References: [CompTIA Network+ Certification Exam Objectives], What Is Split Tunneling? | NordVPN

• A network technician should follow a network troubleshooting methodology to systematically identify and resolve network problems12.
• A network troubleshooting methodology consists of several steps, such as identifying the problem, establishing a theory of probable cause, testing the theory, implementing a solution, verifying functionality, and documenting the results12.
• In this scenario, the network technician has determined the cause of a network disruption, which means that they have completed the steps of identifying the problem, establishing a theory of probable cause, and testing the theory12.
• The NEXT step for the technician to perform is to establish a plan of action to resolve the issue, which means that they should define the steps, resources, and tools needed to implement a solution that can fix the network disruption12.
• Establishing a plan of action to resolve the issue is the next step, because it can help the technician to prepare for the implementation, avoid potential risks or complications, and communicate the plan to the stakeholders12.
• The other options are not the next step for the technician to perform, because they are either previous or subsequent steps in the network troubleshooting methodology12:
