SK0-005 security-disaster-recovery Practice Question

A financial services firm requires a disaster recovery site that provides immediate failover with zero data loss. Which type of site should they implement?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

A hot site with synchronous replication.

Option A is correct because a hot site with synchronous replication ensures that data is written to both primary and secondary sites simultaneously, providing zero RPO and immediate failover. Option B (warm site) requires some time to bring systems online, leading to downtime and potential data loss. Option C (cold site) involves significant setup time and last-known-good backup restoration. Option D (cloud with daily snapshots) introduces an RPO of up to 24 hours, not zero data loss.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • A warm site with asynchronous replication.

    Why it's wrong here

    Warm sites require time to activate and may lose data that hasn't been replicated since the last sync, resulting in a non-zero RPO.

  • A cloud-based site with daily snapshots.

    Why it's wrong here

    Daily snapshots introduce a Recovery Point Objective (RPO) of up to 24 hours, meaning potential data loss of up to a full day.

  • A cold site with tape restoration.

    Why it's wrong here

    Cold sites require hardware setup and tape restoration, leading to significant downtime and data loss up to the last backup.

  • A hot site with synchronous replication.

    Why this is correct

    Synchronous replication ensures data is mirrored in real-time, enabling immediate failover with no data loss.

Same concept, more angles

2 more ways this is tested on SK0-005

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. An organization requires a disaster recovery site that can be operational within 24 hours after a disaster declaration, with critical data replicated on a regular basis, but not necessarily real-time. Which type of site should they implement?

medium
  • A.Warm site
  • B.Alternate processing site
  • C.Cold site
  • D.Hot site

Why A: Option A is correct because a warm site provides pre-installed hardware and network infrastructure, along with data backups that can be loaded and activated within a day. Hot sites offer immediate failover but are more expensive and not necessary here. Cold sites are empty space and take weeks. An alternate processing site is a vague term.

Variation 2. A small business needs a disaster recovery site that can be brought online within 2 hours of a primary site failure. The business can tolerate minimal data loss. Which type of recovery site should they implement?

easy
  • A.Cold site
  • B.Hot site
  • C.Warm site
  • D.Mobile site

Why B: Option C is correct because a hot site maintains near-real-time data replication and preconfigured hardware, enabling failover within 2 hours and minimal data loss. A cold site (Option A) requires hardware setup and data restoration, taking days. A warm site (Option B) has pre-installed hardware but lacks current data, typically taking hours to a day to activate. A mobile site (Option D) is a portable solution with variable provisioning time and may not meet the 2-hour requirement consistently.
