Options

• ALocal disk backup
• BDual-active in the same city
• CMultiple Live in the Same City
• DTwo locations and three centers
• ECloud Disaster Recovery
• FMain backup in the same city

• A

• B
  81% (44)

Explanation

Options B through F all describe recognized data center-level disaster recovery architectures that involve redundant infrastructure, geographic or logical separation, and the ability to maintain or restore financial services after a disaster. Dual-active (B) and Multiple Live (C) in the same city keep all nodes handling live traffic simultaneously, eliminating single points of failure. Two locations and three centers (D) is the classic financial-industry standard - a primary site, a same-city backup, and a remote backup - providing both local and geographic redundancy. Cloud disaster recovery (E) leverages off-site cloud infrastructure for failover, while main-backup in the same city (F) maintains a hot standby ready to take over from the primary within the same metropolitan area.

Option A (local disk backup) is wrong because it is merely a data storage/backup technique on a single machine or server - it provides no geographic separation, no redundant data center, and no ability to sustain operations if the physical site is destroyed. It protects data at the file level, not the site level.

Memory tip: Think of the question as asking "what counts as a data center strategy?" - anything that involves a second (or third) site or system taking over qualifies. Local disk backup never leaves the building, so it fails the "disaster recovery center" test immediately.
