In the 3DR (Data Protection, Disaster Recovery, Doomsday Recovery) model, Remote Backup of Data Protection is termed the “doomsday recovery level,” representing the ultimate offsite safeguard against catastrophic loss.

Option A:Basic local protection, not doomsday-level.

Option B:Long-term storage, not recovery-focused.

Option C:General backup, not remote-specific.

“Remote Backup of Data Protection, dubbed the doomsday recovery level in 3DR, ensures data survival through offsite replication” (Module: Data Protection Strategies, Section: 3DR Model).

A Cold Backup is performed when the database is offline, ensuring data consistency by avoiding changes during the process, as described.

Option A (Online Data Backup):Implies active system backup, not offline.

Option B (Hot Backup):Taken while the system is online.

Option C (Full System Backup):Broad term, not offline-specific.

“Cold Backup occurs with the database offline, ensuring a consistent snapshot without transaction interference” (Module: Data Backup and Recovery, Section: Backup Types).

A Threat is any circumstance or event with the potential to disrupt operations or degrade assets, as described.

Option A (Impact):Result of a threat, not the cause.

Option B (Vulnerability):Weakness exploited by threats.

Option C (Hazard):Natural danger, narrower than “threat.”

“A Threat is any potential event that can disrupt operations or assets, requiring identification for effective DR planning” (Module: Risk Management, Section: Threat Definitions).

Confidentiality in PASIS ensures data is protected from unauthorized access, using encryption and access controls, aligning with Jessie’s goal of restricting access to authorized employees.

Option A (Reaction):Not a PASIS feature.

Option C (Availability):Ensures access, not restriction.

Option D (Maintenance):Not a security feature.

“Confidentiality in PASIS architecture secures data against unauthorized access, employing encryption and controls to safeguard critical information” (Module: Survivable Storage Systems, Section: PASIS Features).

A Hot Site is a fully operational alternate site with duplicated systems and data, running in parallel to the primary site. It allows immediate failover and continuity of operations with minimal downtime, meeting John’s need for near-instant resumption.

Option A (Cold Site):A basic facility with power and space, requiring significant setup time.

Option B (Warm Site):Partially equipped, with some pre-installed systems, but not fully operational in real time.

Option D (Colocation Facilities):Shared data centers, not inherently designed for immediate failover.

“Hot Sites are fully redundant, mirrored environments that operate concurrently with primary sites, ensuring zero to minimal downtime during failover, ideal for critical operations” (Module: Alternate Sites, Section: Site Types).

RAID 3 uses striping with a dedicated parity drive, meeting all requirements: parity for reconstruction, good speed (sequential access), and lower cost than RAID 10 or RAID 1 (fewer drives than RAID 10). Option C duplicates RAID 1, likely a typo.

Option A (RAID 10):Mirroring and striping, expensive, no parity drive.

Option B/C (RAID 1):Mirroring, no parity, costly for multiple drives.

Option D (RAID 3):Parity-based, cost-effective, meets all criteria.

“RAID 3 employs a dedicated parity drive for data reconstruction, offering good performance and cost-efficiency for backup solutions” (Module: Storage Technologies, Section: RAID Levels).

A Team-wide BIA (Business Impact Analysis) evaluates interruptions specific to a department or team due to internal system failures, as described.

Option B (Organization-wide):Covers the entire organization, not department-specific.

Option C (Country-wide):Too broad, not system-focused.

Option D (Branch-wide):Branch-level, not necessarily team/department.

“Team-wide BIA assesses the impact of internal system failures on a specific department, tailoring continuity plans to team needs” (Module: Business Impact Analysis, Section: BIA Scope).

Non-Authoritative Active Directory Restoration is used to restore a domain controller’s Active Directory database from a backup when other domain controllers in the domain are still operational. It allows the restored server to synchronize with the intact servers, updating its directory to the current state. Since Zane’s other servers have intact Active Directories, this method ensures consistency without overwriting domain-wide data.

Option A (Server Migration):Involves moving services to a new server, not restoring AD.

Option B (Data Replication):A general process, not specific to AD restoration.

Option C (Authoritative Restoration):Used when the restored AD data must override others, not applicable here.

“Non-Authoritative Active Directory Restoration recovers a domain controller by leveraging replication from other intact controllers, ensuring domain consistency without forcing changes” (Module: System Recovery, Section: Active Directory Recovery).

Disaster Recovery (DR) encompasses restoring data, applications, and infrastructure post-disaster, ensuring business operations resume, aligning with the question’s broad scope.

Option A (Data Recovery):Limited to data, not applications or infrastructure.

Option C (Application Recovery):Focuses only on applications.

Option D (Recovery Management):A process, not the ability itself.

“Disaster Recovery restores data, applications, and infrastructure after a disaster, enabling business continuity” (Module: Disaster Recovery Planning, Section: DR Definition).

Distributed File System Replication (DFSR) synchronizes the SYSVOL folder across domain controllers in a Windows domain, ensuring consistency. The document’s answer (D) is incorrect; backups don’t synchronize live data.

Option A (Load Balancing):Distributes traffic, not file sync.

Option B (Failover):Switches to backups, not synchronization.

Option D (Data Backup):Copies data, not real-time sync.

“DFSR ensures SYSVOL synchronization across domain servers, maintaining uniform policy and file access” (Module: Server Management, Section: Domain Synchronization).

TheSYSVOL folderin a Windows domain environment contains critical data such as Group Policy objects and logon scripts, and it must be kept synchronized across multiple domain controllers within the same domain.Distributed File System Replication (DFSR)is the technology used in modern Windows Server environments (since Windows Server 2008 and later) to replicate and synchronize the SYSVOL folder across these servers. DFSR ensures that changes made to SYSVOL on one domain controller are efficiently replicated to others, maintaining consistency.

A. Load Balancing: This method distributes network or application traffic across multiple servers to optimize resource use and availability, but it does not handle file synchronization.

B. Failover: This refers to switching to a backup system in case of failure, not synchronizing data between servers.

D. Data Backup: This involves creating copies of data for recovery purposes, not real-time synchronization across servers.

Thus,Distributed File System Replication (DFSR)is the method that keeps the SYSVOL folder synchronized across multiple servers in the same domain.
