Welcome to Certifiable, your exam prep headquarters. Here you'll find questions about some of the tricky areas that are fair game for the certification exams. Following the questions, you'll find the correct answers and explanatory text. We change the questions weekly.
When you have more than one site in your replication system, you must create links to connect the sites for replication. In Active Directory (AD), a site link object identifies a set of sites that you can schedule to communicate at uniform cost through some transport between sites. One of the most important things about sites is that they let you control the parameters for replication. Which of the following parameters can you set for a site link in Active Directory Sites and Services? (Choose all that apply.)
- Replication period
- Replication schedule
Backing up data is a critical task for all network administrators. Typically you want to schedule backups to occur during nonpeak hours so you don't disrupt network users' usual activities. If you use the Windows 2000 Backup utility to do your backups, which of the following types of backup can you schedule to run during nonpeak hours? (Choose all that apply.)
- Authoritative backup
- Differential backup
- Incremental backup
- Non-authoritative backup
- Normal backup
Certain actions require an administrator to boot into Directory Services Restore Mode. Which of the following actions involving Active Directory (AD) require this? (Choose all that apply.)
- An authoritative restore
- A non-authoritative restore
- Offline defragmentation
- Online defragmentation
- A restore of the system state data
Answer to Question 1
The correct answers are B—Cost; E—Replication period; and F—Replication schedule. Site links specify the cost of the link, which controls the desirability of remote sites as sources of replication information. In addition, site links specify the schedule, how frequently periodic replication occurs over the link during the schedule window, and the behavioral options that might influence how replication occurs.
Answer to Question 2
The correct answers are B—Differential backup; C—Incremental backup; and E—Normal backup. There are five backup types: copy, daily, differential, incremental, and normal. You can schedule all of these through the Backup utility and the Task Scheduler. Authoritative and non-authoritative are types of RESTORES. By default, all restores are non-authoritative. To perform an authoritative restore, you must use the Ntdsutil utility.
Answer to Question 3
The correct answers are A—An authoritative restore; and C—Offline defragmentation. An authoritative restore requires that you boot the computer into Directory Services Restore Mode. You must also perform an offline defragmentation, which can reduce the size of the Active Directory (AD) database, while booted into Directory Services Restore Mode.
Non-authoritative restores don't require that you boot the computer into Directory Services Restore Mode. Online defragmentation runs periodically on a domain controller (DC) and doesn't need to happen in Directory Services Restore Mode. By default, restores of the system state data are non-authoritative.
