Resiliency and Recovery II Practice Questions

DataResilient Inc. relies on a cold site for disaster recovery. Which of the following best explains why their recovery process during a power outage was delayed?

• A cold site lacks immediate infrastructure, requiring setup before use.

• Cold sites are geographically closer to the primary site, causing redundancy issues.

• Cold sites require real-time replication, which was disrupted during the outage.

• Cold sites prioritize cost over geographic dispersion.

Which of the following systems at DataResilient Inc. would likely be the most critical during a ransomware attack?

• Learning Management System (LMS)

• Real-time Communication Tools

• Billing and Subscription Management System

• All of the above

Answer explanation

Each system serves a vital role in business continuity, including customer service and financial stability.

How would a multi-cloud system improve resilience for DataResilient Inc.?

• It ensures that all critical systems are hosted in a single, secure cloud environment.

• It allows workloads to shift between cloud providers during outages or attacks.

• It eliminates the need for a disaster recovery site by storing all backups locally.

• It reduces downtime by automatically encrypting data during transit.

Cross-training IT staff is an essential part of capacity planning. How does this strategy improve resilience?

• It reduces recovery time by ensuring key roles can be filled during an incident.

• It eliminates the need for specialized cybersecurity personnel.

• It ensures critical systems are geographically dispersed.

• It automates incident response processes during disasters.

Failover testing ensures that:

• Backup systems can handle live workloads during an outage.

• Incident response plans are reviewed with key stakeholders.

• Cybersecurity personnel can identify vulnerabilities in real-world systems.

• Encryption protocols are correctly implemented during data transfer.

Why is geographic dispersion important for resilience in cloud systems?

• It ensures encryption keys are stored in multiple locations.

• It prevents localized disasters from affecting all critical systems.

• It reduces the cost of disaster recovery solutions.

• It eliminates the need for redundant cloud providers.

Platform diversity enhances resilience by:

• Standardizing all systems on a single operating system.

• Reducing the attack surface by using a mix of operating systems, tools, and providers.

• Ensuring all systems are hosted in a centralized cloud environment.

• Replicating data across a single cloud provider’s geographic locations.

Which of the following testing methods is most likely to reveal communication gaps during an incident?

• a) Tabletop exercises

• b) Failover testing

• c) Security simulations

• d) Parallel processing

Which of the following best describes the purpose of parallel processing during resilience testing?

• • Simulating a cyberattack to evaluate an organization’s response in a controlled environment.

• • Testing backup and recovery procedures alongside live systems without disrupting operations.

• • Running a full failover to a backup site to ensure operational readiness.

• • Conducting a discussion-based exercise to refine incident response plans.

An organization implements redundant resources and scalable systems as part of its resilience strategy. Which of the following scenarios best demonstrates the benefit of this approach?

• • Adding additional servers during a traffic spike to ensure uninterrupted service.

• • Using a single cloud provider to centralize data storage and backup.

• • Storing critical data in a cold site for cost-effective disaster recovery.

• • Encrypting all backup data to prevent unauthorized access.

Answer explanation

Redundant resources provide backup systems to handle failures, while scalable systems allow for dynamic adjustments, such as adding servers, to accommodate increased demand without downtime.
