Lesson 22: Manage Network Services Flashcards
What is the relationship between clients and servers as it relates to network service access?
Client software is used to access network services provided by server software.
The connection is established using a common network protocol known by both the client and server software.
Thus, the client and server software can be from different sources.
What is 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 is the primary interface for configuring network service applications?
Use Internet Accounts preferences as the primary interface in macOS for configuring built-in network applications.
What ability is lost when you upgrade an older Notes service account to support rich media in the Notes application?
When an older Notes service account is upgraded to support rich media, the Notes data is saved to iCloud.
This means you will lose the ability to directly access your notes from versions of macOS earlier than Sierra and versions of iOS earlier than iOS 9.
Older systems can still access Notes from the iCloud website: www.icloud.com.
How does macOS use dynamic network service discovery protocols to access network services?
Devices providing a network service advertise their availability via a dynamic network service discovery protocol.
Clients looking for services request and receive this information to provide you with a list of available network service choices.
Which two dynamic network service discovery protocols are supported by macOS?
macOS supports Bonjour and Server Message Block (SMB), including support for legacy Network Basic Input/Output (NetBIOS) and Windows Internet Naming Service (WINS) dynamic network service discovery protocols.
Which five network file services can you connect to from the Finder’s “Connect to Server” dialog?
From the Finder’s “Connect to Server” dialog, you can connect to:
- 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’s Network folder populated?
The Finder populates the Network folder using information provided by the dynamic network services discovery protocols.
Computers providing services appear as resources inside the Network folder, whereas service discovery zones or workgroups appear as folders.
Any currently connected servers also appear in the Network folder.
Which two methods can be used to automatically connect a network share?
To automatically connect a file share when you log in, drag the share from the Finder to your login items in Users & Groups preferences.
Alternatively, you can drag the share to the right side of your Dock, and it will automatically connect when you click the share’s icon in the Dock.
What are three common troubleshooting techniques for issues involving failure to connect to network services?
To troubleshooting issues involving failure to connect to network services, review Network preferences, review the Network Utility statistics, and attempt to connect to different network services.
How can you verify that a specific network service is available from a service provider?
To verify that 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 port(s) are open.
You should always limit the port scan to the specific ports required for the network service you are testing.
