Manage Network Services Flashcards
What’s the relationship between clients, servers, and network service access?
Client software accesses network services that server software provides. The slicing and server software use network protocols and standards to communicate with each other.
What do you need to access a network service?
The service’s local network or internet location
What is authentication?
Security technologies in place to ensure that you’re allowed to access only certain resources
What does dynamic network service discovery protocols enable you to do?
Browse LANs and WANs resources without knowing specific server addresses.
What are two examples of how macOS uses dynamic network service discovery?
- Browse for available network file shares with the Finder
2. Locate new network printers from Printers and Scanners preferences
What is Zero Configuration Networking, or Zeroconf?
A collection of standards drafts that provide automatic local network configuration, naming, and service discovery.
What broadcast discovery protocol does Bonjour use?
Multicast DNS (mDNS) on UDP port 5353
What is Bonjour?
The Apple implementation of Zeroconf, that is the primary set of dynamic network service discovery protocols used by macOS-native services and apps.
Why does Bonjour integrate so well with other TCP/IP-based network services?
Because Bonjour is based on TCP/IP standards
What is Server Message Block (SMB)?
The most common network service for sharing files and printers
What are the 5 network host identification methods?
- IP address
- DNS Hostname
- Computer name
- Bonjour name
- NetBIOS name
What are the two methods your Mac configures its hostname?
- macOS attempts to resolve its hostname by performing a DNS reverse lookup on its primary IP address.
- If it can’t, it uses the Bonjour name instead
What is the NetBIOS name?
The legacy Windows dynamic network discovery protocol as part of the SMB service.
What’s the relationship between a network service and a network port?
Network services are established using a common network protocol. The protocol specifies which TCP or User Datagram Protocol (UDP) port to use for communications.
What handles web communication for Safari by using TCP port 80?
Hypertext Transfer Protocol (HTTP)
What’s the primary interface for configuring network service apps, such as Mail, Calendars, Notes, Reminders, Contacts, and Messages
Internet Accounts preferences

True/False: The Apple ID you sign into on Messages, has to match the Apple ID you sign into iCloud with.
False, they do not have to match. As long as you sign into Messages with a valid Apple ID, the messages app will work. However, for syncing purposes, it is recommended that you sign into iCloud and Messages with the same Apple ID
How can users join a FaceTime call without an Apple ID in macOS Monterey?
They will join in a browser.
How are items inside the Finder Network folder populated?
By using information that the dynamic network service discovery protocols provide. Computers that provide services appear as resources inside the Network folder, and service discovery zones or workgroups appear as folders.
What are the 5 network file service protocols that macOS provides built in support?
- Server Message Block version 3 (SMB 3)
- Apple Filing Protocol (AFP)
- Network File System (NFS)
- Web-based Distributed Authoring and Versioning (WebDAV)
- File Transfer Protocol (FTP)
What are the two ways to get to the Network folder?
- Click “Network” in the Finder sidebar
2. Choose Go > Network (or press Shift-Command-K)
What are the three methods your Mac uses to AUTOMATICALLY authenticate when you attempt to connect to a Mac that provides file-sharing services?
- Kerberos credentials (If using Kerberos single sign-on)
- If you’ve connected before, your Mac attempts to used the saved authentication information
- Your Mac attempts to authenticate as a guest user
What are the three methods your Mac uses to MANUALLY authenticate when you attempt to connect to a Mac that provides file-sharing services?
- Authenticate as a Guest to connect anonymously to the file service
- Select “Registered User” to authenticate using a local or network account known by the computer providing the shared items
- Using an Apple ID, if it appears as an option
How do you connect manually to an SMB or AFP?
- Choose Go > Connect to Server (Command-K)
2. Type in either smb:// or afp:// followed by the server IP address, DNS hostname, computer name, or Bonjour name.
How can you make Mounted servers appear on the Desktop?
Finder Preferences > General > Check box for Connect servers

- Create a shortcut by dragging the network share to the right side of the Dock
What website can you check real-time Apple service statuses?
www.apple.com/support/systemstatus

Gives you an idea about which ports are open and available to provide network services.
What is the basic first step to troubleshoot a network service?
“ping”
- Open Terminal
- Enter “ping”, then press the Space bar
- Enter the device network address or hostname
- Press Return
If successful, press Control-C or Command-Period to stop the ping command
What three things do you need to check to verify that a specific network service is available from a service provider?
- Verify basic connectivity (ping terminal command)
- Verify DNS resolution (nslookup, dig, host, or dscacheutil terminal commands)
- Verify that the specific service ports are open (nc terminal command)
How can you troubleshoot web browser issues?
- Adjust how browser works with certain websites. For example, Safari > Preferences > Websites can customer how Safari acts with various websites
- Install Safari extensions to customize the way your browser works
