Lesson 24: Manage Network Services Flashcards
• Describe how macOS accesses shared network services. • Configure built-in macOS network apps. • Browse and access network file services using the Finder. • Troubleshoot network shared service issues.
What’s the relationship between clients, servers, and network service access?
Client software is used to access network services that are provided by server software.
The client and server software use network protocols and standards to communicate with each other.
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 UDP port number is used for communications.
What’s the primary interface for configuring network service apps?
Internet Accounts preference is the primary interface in macOS High Sierra for configuring built-in network apps.
How does macOS High Sierra use dynamic network service discovery protocols to access network services?
Devices that provide a network service advertise their availability through a dynamic network service discovery protocol.
Clients who are looking for services request and receive this information to provide the user with a list of available network service choices.
Which two dynamic network service discovery protocols are supported by macOS High Sierra?
macOS High Sierra supports Bonjour and Server Message Block (SMB), including support for the legacy Network Basic Input/Output System (NetBIOS) and Windows Internet Naming Service (WINS) dynamic network service discovery protocols.
Which five network file services can you connect to from the Finder “Connect to Server” dialog?
From the Connect to Server dialog in the Finder, you can connect to these services and systems:
- Server Message Block / Common Internet File System (SMB / CIFS), including SMB2 and SMB3
- Apple File Protocol (AFP)
- Network File System (NFS)
- Web-based Distributed Authoring and Versioning (WebDAV)
- File Transfer Protocol (FTP) network file services
How are items inside the Finder Network folder populated?
The Finder populates the Network folder using information provided by the dynamic network services discovery protocols.
Computers that provide services appear as resources inside the Network folder, and service discovery zones or workgroups appear as folders.
Any currently connected servers also appear in the Network folder.
In what two ways can you automatically connect a network share?
To automatically connect a file share when a user logs in to the system, drag the share from the Finder to the user’s login items in Users and Groups preferences.
Or you can drag the share to the right side of the user’s Dock, and it will automatically connect when the user clicks the share’s icon in the Dock.
What are three common troubleshooting techniques you can use when you can’t connect to network services?
Review Network preferences, review the Network Utility statistics, and try to connect to different network services.
How can you verify that a specific network service is available from a service provider?
To verify whether a specific service is available from a service provider, first use the Network Utility Ping tab to verify basic connectivity.
Then use the Network Utility Port Scan tab to verify that the specific service ports are open.
You should always limit the port scan to the specific ports required for the network service you’re testing.
