Cost-Effective Disaster Recovery Simulation Strategy

SK0-005 By islever Editorial Last updated

Short answer

B Build a cloud IaaS and perform a fail over of the application.

Question

A company wants to find an affordable way to simulate a fail over of a critical application. The company does not currently have a solution for it. The application consists of 15 servers, and the company would like to simulate on production configurations and IP address schemes. Which of the following would be the most cost-effective solution?
  1. Build a warm site and perform a fail over of the application.
  2. Build a cloud IaaS and perform a fail over of the application. Correct Answer
  3. Build a hot site and perform a fail over of the application.
  4. Build a cold site and perform a fail over of the application.
  5. Perform a tabletop fail over of the application.

Key Takeaways

Tests the distinction between 'tabletop exercises' (discussion-based) and actual technical simulations, while balancing cost against the requirement to test IP schemes and server configurations.

The question asks for the most cost-effective way to simulate a failover using production configurations. Community consensus favors Cloud IaaS (Option B) as it offers affordable, on-demand infrastructure without the high capital expenditure of physical sites.

Common mistake: Candidates often choose Tabletop (Option E) because it is technically free or low-cost; however, tabletop exercises are discussion-based role-playing and do not involve actual system simulation or IP scheme validation.

Expert Analysis

Why the Answer Is Correct

Cloud IaaS (Option B) allows the organization to spin up temporary virtual servers that mirror production configurations and IP schemes without purchasing permanent hardware. This pay-as-you-go model makes it significantly more cost-effective than building and maintaining dedicated physical disaster recovery sites.

Why the Other Options Are Wrong

Warm sites (A) and Hot sites (C) require significant ongoing maintenance and hardware costs, making them expensive for a one-time simulation. Cold sites (D) lack pre-provisioned hardware, requiring time to install systems, which defeats the purpose of a quick simulation. Tabletop (E) is a discussion exercise, not a technical simulation of the application stack.

Community Comment Notes

Comment [1] correctly highlights that 'simulation' implies technical execution, ruling out tabletop discussions. Comment [4] argues for E based on pure monetary cost but fails to meet the technical definition of simulating server and IP configurations provided in the CompTIA context.

Exam Strategy

When a question mentions 'simulation' involving technical components (like IPs or servers), eliminate discussion-only methods like Tabletop. Prioritize solutions that offer scalability and pay-per-use pricing (like Cloud IaaS) when 'cost-effective' is the primary constraint alongside technical requirements.

    Simulate and simulation are mentioned. Tabletop does not simulate. Tabletop is a discussion of a hypothetical situation and what could and should happen. Out of the remaining answers, B is the most cost effective to get this done.
  2. ccoli 👍 2
    Tabletop isn't really a simulation. B is the correct answer.
  3. Stache 👍 1 Answered E
    Correct answer is E, all other option are very cost-intensive. From CompTIA Server+ Student Guide: Tabletop/Simulated failover—the disaster recovery procedures are implemented on a limited scale. Participants engage in role-playing to ensure comprehension and realism.

    I am going to vote E because its free (besides paying the empoyees) it does say cost effective.
