   Which of the following is the first step to troubleshoot a network issue?

   • AIdentify the problem.
   • BDocument the findings.
   • CEstablish a theory of probable cause.
   • DTest the theory to determine the cause.

   Show answer

   Answer: A

   Explanation

   The troubleshooting process typically begins with identifying and defining the problem clearly. This initial step involves gathering information about the issue, such as the symptoms, the scope, and any recent changes to the network or systems. After identifying the problem, you would proceed with documenting findings, establishing a theory of probable cause, and testing that theory to determine the cause.

   Explanation

   A client-to-site VPN (also known as a remote access VPN) allows individual employees to securely connect to the company’s network from remote locations using their devices. This provides a secure tunnel over the internet, ensuring that remote users can access the company’s resources as if they were on-site.

   • AMultifactor
   • BRADIUS
   • CSSO
   • DLocal authentication

   Show answer

   Explanation

   Single Sign-On (SSO) permits a user to use one set of login credentials (e.g., username and password) to access multiple applications. SSO can allow a user to access a third-party website without needing to enter a password specifically for that site, as long as the user is already authenticated through a central SSO service.

   Which of the following is required for hosts to receive DHCP addresses from a server that is located on a different subnet?

   • ADHCP scope
   • BDHCP snooping
   • CDHCP reservations
   • DDHCP relay

   Show answer

   Answer: D

10. Question 790 · 871 in bank

    A network engineer needs to change an entire subnet of SLAAC-configured workstation addresses. Which of the following methods would be the best for the engineer to use?

    • AChange the address prefix in ARP in order for the workstations to retrieve their new addresses.
    • BChange the address prefix in a router in order for the router to advertise the new prefix with an ND.
    • CChange the address prefix scope in a DHCP server in order for the workstations to retrieve their new addresses.
    • DChange the workstations’ address prefix manually because an automated method does not exist.

    Show answer

    Answer: B

    Explanation

    In SLAAC, workstations use router advertisements (RAs) sent by routers to configure their IP addresses based on the advertised prefix. By changing the address prefix on the router, the router will advertise the new prefix through the ND protocol. Workstations will then automatically update their addresses based on the new prefix provided in the RA messages.
