What are the minimum RAM and hard drive requirements for
installing OS X Server?
The minimum RAM and hard disk requirements for OS X
Server are:
• 2GB of RAM (more for high-demand servers running
multiple services)
What tool do you use to perform an installation and initial
configuration of OS X Server?
You use the Server app to perform an installation and initial
configuration of OS X Server.
If you’re installing OS X Server on a Mac, what is one
configuration step you should take before installing?
Configure your Mac with OS X to use a manually assigned
IPv4 address.
What are two kinds of names associated with your server, and
what are they used for?
You can use the Server app to configure these two names:
• Computer name—This is what appears in the Finder
sidebar for other Macs if your server offers file sharing
services.
• Host name—Computers and devices can access services
offered by your server by using your server’s DNS host
name, even if they’re not on its local network, as long as the
host name corresponds with an IPv4 address that reachable
and not blocked by firewalls.
How can you install the Server app on an administrator
computer?
You can use the Mac App Store to download OS X Server, or
just copy the Server app to your Applications folder.
What is the purpose of DNS?
To convert host names into IP addresses and IP addresses to
host names.
If no DNS server is defined when configuring OS X Server,
how will the server provide DNS for itself?
A basic DNS server is configured automatically and turned on.
If you’re using an external DNS server to provide DNS for your
server, what should you do prior to configuring the server?
You should check that the DNS server has the proper forward
and reverse DNS information configured for your server’s host
name and IPv4 address.
When is it OK to leave the automatically configured DNS
server running with no modification?
When it’s a very simple network with one server, and all the
computers and devices are on the same network.
When might you want to use a manually configured DNS
service on your OS X Server?
When you want to have records for multiple computers and
devices.
Using an administrator computer with the Server app
installed, how do you use the Server app to administer a
remote server?
Open the Server app, choose Manage > Connect to Server,
select your remote server from the list (or select Other, and
then provide its host name or address), and provide
credentials for a local administrator.
What option do you need to select in order to allow another
Mac to administer your server, and where is its checkbox?
Select your server in the Server app sidebar (in the Hardware
section), click the Settings tab, and then select the option
“Allow remote administration using Server.”
What applications can you quickly access through the Tools
menu?
The Tools menu gives you access to these applications:
• Directory Utility
• Screen Sharing
• System Image Utility
• Xsan Admin
Do you have to install extra software to take control of your
server’s keyboard and mouse?
No, you don’t have to install extra software. On your server
computer, open the Server app and select your server in the
Server app sidebar (in the Hardware section). Click the
Settings tab, select the checkbox “Enable screen sharing and
remote management,” and then on your administrator
computer use Screen Sharing to take control of your server
computer’s keyboard.
How do you hide the Next Steps drawer?
Click the Next Steps button, or choose Help > Next Steps
Button.
If you use the Server app to choose a different service data
volume to a volume called /Volumes/Data, what folder will
contain the service data?
In this case, your service data will be stored in /Volumes/Data/
Library/Server.
Do you need to stop all services before using the Server app
to change your service data volume?
No, the Server app automatically stops the appropriate
services before moving the data to the new service data
volume.
Can you remotely install OS X Server on a brand new Mac
computer that comes with OS X Server, without first
configuring OS X on that computer?
No, you need to configure OS X before installing and
configuring OS X Server.
What is the difference between a root CA and an
intermediate CA?
An intermediate CA’s public key certificate is signed by
another CA. A root CA’s public key certificate is signed by
itself. Note that there’s a set of root CAs and intermediate CAs
that OS X trusts.
What is the problem with just using a self-signed SSL
certificate?
Computers and devices accessing services that use a selfsigned
SSL certificate will see a message that the SSL
certificate is not trusted. It’s a security risk to teach users to
just trust any SSL certificate that causes a warning.
What tool do you use to create a new self-signed SSL
certificate and a CSR?
Use the Server app to create a new self-signed SSL certificate
and a CSR.
What do you need before you can create a CSR?
You need a self-signed SSL certificate before you can use it to
create a CSR.
What is the purpose of alerts?
Alerts provide a system of warning of various conditions.
What are the two ways alerts can be delivered?
Email and alerts pushed to the Server app
If you wish to use push alerts, what is the first step you need
to take?
Configure the Apple Push Notification service for the server
that you’re using.
If an alert details offers to update services, what is the correct
action?
Understand the alert and rectify the situation before making
any configuration changes, as they may be unneeded.
Which volumes are shown in the Storage tab in the Server
app?
All volumes that are visible and mounted on the server.
Why use Time Machine to back up OS X Server?
Time Machine provides a simple backup system that’s
capable of backing up OS X Server and restoring its services.
What files are not backed up by Time Machine that might be
important in a server to a system administrator?
/Library/Logs/ is not backed up.
What kind of backup targets can be used for Time Machine?
Locally connected volumes and AFP file shares.
If you don’t want to drop the oldest backups, what should
you do?
Don’t let the backup target volumes fill up because the oldest
backups will be dropped.
What are three ways of recovering data from a Time Machine
backup?
From the Time Machine graphical interface, directly from the
backup volume, and via Restore from Time Machine Backup
in the Recovery volume.
Describe the difference between authentication and
authorization, and give an example of each.
Authentication is the process by which the system requires
you to provide information before it allows you to access a
specific account. An example is entering a name and
password while connecting to the Apple Filing Protocol
service. Authorization refers to the process by which
permissions are used to regulate a user’s access to specific
resources, such as files and shared folders, once the user has
been successfully authenticated.
What is the difference between user and administrator
accounts on OS X Server?
User accounts provide basic access to a computer or server,
whereas administrator accounts allow a person to administer
the computer. On OS X Server, an administrator account is
typically used for changing settings on the server computer
itself, usually through the Server app.
Which applications can you use to configure OS X Server local
user and group settings?
You can use the Users & Groups preferences and the Server
app to create and configure local user and group settings.
What tool can you use to import and export user accounts?
You can use the Server app to import and export user
accounts. Additionally, as you’ll see in the next lesson, you can
use the Server app to import network users after you
authenticate as a directory administrator.
Which two formats of files can you use to import users with
the Server app?
You can use the Server app to import a character-delimited
text file with user information, but you need a header line to
define the characteristics of the information contained in the
file. You can also import a text file that has a header line at
the beginning of the file that defines the contents of the file.
If you decide to manually manage access to services, what are
some services included in the list?
Services include Calendar, Contacts, File Sharing, FTP, Mail,
Messages, Profile Manager, Time Machine, and VPN.
When you select the checkbox to grant authorization for a
user to access File Sharing services, what file sharing
protocols does this enable for the user?
Authorization to use File Sharing includes AFP and SMB
protocols.
When you click the Manage Service Access button, does this
prevent users that you create in the future from being able to
access your OS X Server services?
No, even after you choose to manage service access
manually, new users that you create automatically get
authorization to access services. Of course, you can edit a user
and remove authorization for that user to access a service.
