Guide - Part 7: Network Services Flashcards
What’s 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’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 applications?
Internet Accounts preference is the primary interface in OS X for configuring built-in network applications.
How does OS X 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 the user with a list of available network service choices.
Which two dynamic network service discovery protocols are supported by OS X?
OS X supports Bonjour and Server Message Block (SMB), including support for legacy Network Basic Input/Output and Windows Internet Naming Service (NetBIOS and WINS) dynamic network service discovery protocols.
Which five network file services can you connect to from the “Connect to Server” dialog in the Finder?
From the “Connect to Server” dialog in the Finder, you can connect to:
- Server Message Blocks/Common Internet File System (SMB/ CIFS)
- SMB2/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 populated inside the Network folder in the Finder?
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, and 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 the user logs in to the system, drag the share from the Finder to the user’s login items in Users & 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 for 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 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 port(s) are open. You should always limit the port scan to the specific ports required for the network service you’re testing.
What are some known issues that arise when connecting to network file services?
Files with metadata may cause problems for NFS or WebDAV network file systems. Also, avoid AFP 2 services provided by Windows file servers.
Which sharing services can OS X provide?
The OS X sharing services include DVD or CD sharing, Screen Sharing, File Sharing, Printer Sharing, Scanner Sharing, Remote Login, Remote Management (ARD), Apple Events, Internet Sharing, and Bluetooth Sharing.
What’s the security risk of enabling client sharing services?
If a client sharing service is compromised, an unauthorized user can control your Mac and execute unwanted applications or processes.
Which application can provide on-demand screen sharing
even when the Screen Sharing service isn’t enabled?
The Messages application allows for on-demand screen sharing that can be used even when the system screen sharing service isn’t enabled.
What’s AirDrop, and how do you know if a specific Mac supports it?
AirDrop provides a quick and easy method to share files locally via Wi-Fi. AirDrop creates a secure peer-to-peer network between local devices. You can verify that a Mac supports AirDrop from the Finder Go menu.
