Read the first 7 Network Configuration flashcards as text

  1. A technician needs to remove a stubborn network location profile from a Mac managed by MDM. Where should they look first?

    Answer: Profiles section in System Settings

    MDM-deployed network profiles appear in System Settings > Privacy & Security > Profiles (or General > Device Management), where they can be reviewed and removed if authorized.

  2. Which protocol does macOS use by default to automatically discover printers, file shares, and other services on a local network without requiring manual configuration?

    Answer: Bonjour (mDNS)

    Bonjour uses multicast DNS (mDNS) and DNS-SD to advertise and discover services on a local network without a central server.

  3. A user reports that their Mac connects to the corporate VPN successfully but cannot reach internal servers by hostname, only by IP. What is the most likely cause?

    Answer: The VPN is not pushing internal DNS server settings to the Mac

    When the VPN does not push internal DNS server addresses, the Mac continues using its default DNS servers which cannot resolve internal hostnames.

  4. What is the function of the 'networksetup -setdnsservers' command in macOS Terminal?

    Answer: Assigns custom DNS server addresses to a specified network service

    The `networksetup -setdnsservers ` command sets the DNS servers for the specified network interface from the command line.

  5. A Mac on a school network receives an IP but the user cannot browse to any website. Pinging 8.8.8.8 succeeds but pinging google.com fails. What is the problem?

    Answer: DNS resolution is failing

    Successfully pinging an IP address but failing to ping a hostname confirms DNS resolution is not working, as IP routing is functional.

  6. In macOS Network settings, what is the purpose of configuring a 'Search Domain'?

    Answer: It appends the domain to short hostnames so they resolve correctly on a local network

    A search domain causes macOS to append the domain suffix to unqualified hostnames (e.g., 'server' becomes 'server.company.local') enabling local name resolution.

  7. Which macOS feature creates an encrypted tunnel between a Mac and a private network, and is configurable directly within System Settings without third-party software for IKEv2 connections?

    Answer: VPN (built-in IKEv2/IPSec client)

    macOS includes a built-in VPN client supporting IKEv2, IPSec, and L2TP protocols, configurable in System Settings > VPN without additional software.
