Which statement best describes incremental backups?
They save all data every time regardless of changes.
They save only changes since the last backup and update the archive bit.
They save changes since the last full backup without resetting markers.
They create read-only images mainly for deployment.
Why can restoring from incremental backups take longer than other methods?
Because you need the full backup plus all subsequent incremental backups.
Because the archive bit is never updated.
Because incremental backups include the entire drive each time.
Because they are stored as read-only images.
Differential backups grow larger over the week primarily because they:
reset the archive bit after each run.
do not reset the marker, accumulating all changes since the last full backup.
include the entire operating system each time.
are stored in the cloud by default.
Which backup type usually restores faster than incremental backups because only the full backup and the latest backup of that type are needed?
Differential backups
Incremental backups
Snapshot backups
Archives
What is a snapshot in the context of backups?
A long-term storage method optimized for space and legal retention.
A read-only copy of data at a specific point in time, often used for VMs and services like Active Directory.
A full backup combined with all incrementals.
A method that saves changes since the last full backup and resets markers.
Which scenario is the best use case for archives?
Rapid recovery of frequently changing user files.
Capturing system state for quick OS restore after misconfiguration.
Keeping data for a long time to meet legal or regulatory requirements, optimized for space.
Creating point-in-time images for deploying systems.
Which statement correctly distinguishes archives from backups?
Both are optimized for quick access during restores.
Archives are meant for long-term retention, while backups protect against loss or corruption.
Backups store old data rarely accessed, while archives are used for rapid recovery.
Archives always include entire drives; backups never do.
What do system-state backups primarily copy, and why are they useful?
All user files, enabling complete data restores.
Important operating system settings, allowing quick OS recovery if system files are corrupted or misconfigured.
Entire disks, making them ideal for migrating large datasets.
Only application data, to speed up user file recovery.
Which statement best distinguishes an archive from a backup in IT operations?
An archive is a short-term copy used for rapid disaster recovery; a backup is for long-term retention of inactive data.
An archive preserves data for long-term retention and regulatory or historical needs; a backup creates recoverable copies to restore systems or files after loss or corruption.
Both archives and backups are designed primarily for quick failover of active systems.
Backups eliminate the need for archives by storing only inactive data indefinitely.
A company must keep closed project files for seven years to meet compliance requirements but does not need to restore them quickly if lost. Which strategy is most appropriate?

An organization keeps daily backups on local disk, weekly copies on tape sent to a secure vendor, and replicates key datasets to cloud storage. Which statement is most accurate?
This violates the 3-2-1 rule because it uses more than two media types
This follows the 3-2-1 rule because it keeps multiple copies on different media with at least one offsite
This is noncompliant because cloud copies cannot be offsite
This is inadequate because no copies remain onsite

Set identical hourly backups for all data types
Tailor backup frequency to each data type’s rate of change and business value
Back up only after incidents to save space
Replace backups with server-to-server replication only
Which statement best describes asynchronous replication in a data retention context?
The client receives confirmation only after both primary and secondary have committed the write
Data is first written to the primary; the client is confirmed, and then the data is copied to the secondary
The client writes directly to the secondary to reduce latency
No confirmation is sent to the client until a periodic batch copy completes
In asynchronous replication, what is the primary risk if the primary server fails before the secondary has fully received the data?
Data duplication on the secondary
Client-side corruption of the write request
The client believes the data is safe, but the data can be lost
An automatic rollback will always restore the data
A company needs zero data loss upon primary failure. Based on the material, which replication confirmation behavior should they require?
Confirm the write to the client after the primary commits, then copy to secondary later
Confirm to the client only after both primary and secondary have the write
Confirm only after a daily backup job completes
Confirm to the client immediately upon request receipt without any commit
Which sequence correctly reflects the message flow in asynchronous replication?
Client -> Secondary commit -> Primary confirm -> Client confirm
Client -> Primary commit -> Client confirm -> Copy to Secondary -> Secondary confirm -> Primary confirm
Client -> Primary and Secondary simultaneous commit -> Client confirm
Client -> Primary queue -> Daily batch to Secondary -> Client confirm next day

Side-By-Side Restoral
Snapshot Restoral
Alternate Location Restoral
During a post-incident review, you must compare the current configuration of a service with how it looked last Friday at noon. Which recovery option provides the strongest evidence for this comparison?
In-Place Restoral because it merges current and past states
Snapshot Restoral because it captures an exact point in time
Granular File Restoral because it retrieves single files only
Alternate Location Restoral because it changes the recovery path
Which statement best differentiates Snapshot Restoral from Granular File Restoral?
Snapshots recover only individual files; granular restores entire systems.
Snapshots provide point-in-time recovery for VMs or services; granular targets specific files and versions.
Granular restoral moves data across regions; snapshots only restore locally.
Granular restoral always overwrites existing directories; snapshots always create new ones.
