Maintaining and Supporting a Network Flashcards
You need to ensure that your server supports a new disk standard—what would you do?
Purchase a new server that supports the new standard.
Go to the server manufacturer’s website and see if there is a BIOS update for that server that will update the BIOS code to make the server aware of the new standard.
Format the hard drives and then restore the data.
Go to the server manufacturer’s website and see if there is a BIOS update for that server that will update the BIOS code to make the server aware of the new standard.
It is important to remember that as your hardware gets older you can update the BIOS or ROM code on that server or device to bring it up to date with features or technologies that have come out since the manufacturer built the device
You are going to upgrade your e-mail server software to a new version. What should you do before the software upgrade?
Perform the upgrade on a test system first.
Delete the e-mails from the server—you need the space for the new software.
Back up the server before attempting the upgrade.
Both A and C.
Both A and C.
Before performing any kind of hardware or software upgrade, you should make sure that you have tested the upgrade first. After you have tested the upgrade, before performing the upgrade on a production server, make sure that you have backed up the production server in case something goes wrong
What is a hot-fix?
An update that is noncritical
A number of updates that are bundled and will bring your system up to date
A critical update that should be applied to your system as soon as possible
A critical update that should be applied to your system as soon as possible
A hot-fix is a critical update that cannot wait for the next service pack to be supplied. You should apply hot-fixes right away. Make sure that you have tested the hot-fix on a test system first
What feature of Microsoft operating systems allows you to update the system fairly easily?
System Restore
Windows Messenger
Windows Update
Windows Update
Windows Update is a feature of Microsoft operating systems that allows the user to use Windows Update to connect to the Windows Update site, from which updates are downloaded for that operating system
What Microsoft feature can you use to deliver updates to all clients on the network from a central point?
Windows Update
Backup
WSUS
WSUS
Windows Server Update Service (WSUS) can be installed on a Windows server and allows you to manage deployment of patches and updates from a central point
What is the name of malicious software that monitors Internet activity?
Virus
Worm
Spyware
Spyware
Spyware is malicious software planted on your system that can monitor your Internet activity
It is critical that you keep what part of your virus protection software up to date?
Menu commands
Viruses
Virus definitions
Virus definitions
It is critical that you keep your virus definitions up to date. The virus definitions are the part of the virus protection software that makes the software aware of what viruses exist. Virus protection software vendors are constantly updating their definitions, and you can download the updates from the Internet through the virus protection software
What feature of virus protection software is responsible for protecting your system at the time a file with a virus is activated?
Real-time protection
At-the-time protection
Active protection
Real-time protection
Real-time protection saves you from needing to run a virus scan manually because as you open or access files, the virus protection software scans the file being accessed
What type of backup backs up files that have changed and then clears the archive bit?
Full
Incremental
Differential
Incremental
Incremental backups clear the archive bit after backing up a file that has changed. Because the archive bit is cleared, the file will not be backed up with the next incremental backup unless it is changed again
You have been performing a full backup every Sunday night and have been doing incremental backups on Monday, Tuesday, Wednesday, and Thursday nights. Your server crashes during the day on Wednesday. What is your restore strategy?
Restore only Tuesday night’s backup.
Restore the last full backup from Sunday and then restore the last incremental, which is Tuesday’s.
Restore the last full backup from Sunday and then restore the incremental backups from Monday and Tuesday.
Restore the last full backup from Sunday and then restore the incremental backups from Monday and Tuesday.
You will need to restore the last full backup and each incremental backup up to the crash in this scenario. Each incremental backup applies the changes since the previous incremental, and all incrementals build on the full backup being performed, bringing the server up to date
Where should you make certain that you have stored a copy of your network backups?
In your manager’s office
On a different server for quick restores
Offsite in a safe, trusted location
Offsite in a safe, trusted location
You should make sure that you store a copy of your backups offsite in a safe, trusted location. The purpose of having the tapes stored offsite is to be able to recover from a disaster to your premises that would destroy servers and backups
What type of backup backs up files that have changed and does not clear the archive bit?
Full
Incremental
Differential
Differential
A differential backup backs up any file that has changed, but does not clear the archive bit. This is useful because each differential backup includes all changes from the time of the last full backup to the time of the differential backup
You have been performing a full backup every Sunday night and have been doing differential backups on Monday, Tuesday, Wednesday, and Thursday nights. Your server crashes during the day on Thursday—what is your restore strategy?
Restore only Wednesday night’s backup.
Restore the last full backup from Sunday and then restore the last differential backup, which is Wednesday’s.
Restore the last full backup from Sunday and then restore all of the differential backups from Monday and Tuesday.
Restore the last full backup from Sunday and then restore the last differential backup, which is Wednesday’s.
For this scenario you would restore Sunday’s full backup to create a starting point and then apply the last differential backup to bring the server up to date to the time of the last differential
How would you make sure that you do not forget to perform a backup each night?
Create a backup plan.
Schedule the backup software to do the backup automatically.
Ask your manager to remind you to do the backup each night.
Schedule the backup software to do the backup automatically.
The best thing to do is to schedule your backups so that you are not dependent on memory and they are performed automatically
Before performing a backup operation, what should you have in place to ensure that everyone knows and understands the backup strategy?
An assistant
A backup plan
A security document
A backup plan
Make sure that you have a backup plan and that it is up to date so that all systems administrators know what is being backed up and what the restore strategy is in case of failure
