Tier 4 in DR tier models (e.g., SHARE) uses point-in-time copies (e.g., snapshots) for recovery, balancing cost and data loss.

Option B (Tier 5):Adds remote replication, not just point-in-time.

Option C (Tier 0):No backup.

Option D (Tier 6):Near-zero data loss, beyond simple copies.

“Tier 4 employs point-in-time copies to provide reliable recovery with moderate RPO, suitable for many organizations” (Module: Disaster Recovery Tiers, Section: Tier Definitions).

In PASIS architecture, increasing confidentiality (e.g., via encryption) increases storage requirements due to added overhead (e.g., metadata, keys).

Option A (Reaction):Not a PASIS feature.

Option B (Latency):May increase, but not direct as storage.

Option D (Durability):Unaffected by confidentiality.

“Higher confidentiality in PASIS, through encryption, directly increases storage needs due to additional data overhead” (Module: Survivable Storage Systems, Section: PASIS Trade-offs).

Colocation Facilities involve renting space and infrastructure (e.g., cooling, power) in a shared data center, offering a cost-effective backup site solution, as Jack chose.

Option A (Hot Sites):Fully operational, expensive, not cost-focused.

Option B (Cold Sites):Basic space, no pre-installed infrastructure like cooling.

Option C (Warm Sites):Partially equipped, more costly than colocation.

“Colocation Facilities provide cost-efficient backup by renting shared data center resources, including cooling and security, ideal for budget-conscious organizations” (Module: Alternate Sites, Section: Site Types).

A Synthetic Backup combines a full backup with subsequent incremental backups to create an updated full backup, as described.

Option A (Incremental):Only changes, not combined with full.

Option B (Differential):Changes since last full, not synthesized.

Option D (Incremental Forever):Continuous incrementals, not full synthesis.

“Synthetic Backup merges a full backup with incrementals, creating an efficient, updated full copy for recovery” (Module: Data Backup and Recovery, Section: Backup Techniques).

Tier 6 in DR tier models (e.g., SHARE) provides automated recovery of data and applications with near-zero downtime and data loss, fitting Phil’s scenario.

Option A (Tier 4):Point-in-time copies, less automated.

Option B (Tier 7):Fully mirrored, zero loss, more than needed here.

Option D (Tier 2):Basic offsite backup, not automated.

“Tier 6 offers automated recovery of data and applications, minimizing manual intervention and downtime” (Module: Disaster Recovery Tiers, Section: Tier Definitions).
