Which DR testing method carries the HIGHEST risk to production operations but provides the most realistic validation?
Answer: Full interruption test
A full interruption test shuts down the primary site completely and forces all operations to run on the DR site, providing the most realistic test but risking actual business disruption if the DR site fails.
In DR planning, 'single point of failure' (SPOF) analysis is conducted to:
Answer: Identify components whose failure would disrupt the entire recovery process
SPOF analysis identifies any component — hardware, software, network, or personnel — that, if it fails, would halt recovery entirely, allowing planners to add redundancy where needed.
What does 'geographic diversity' mean in the context of DR site selection?
Answer: Ensuring the DR site is far enough from the primary to avoid the same localized disaster
Geographic diversity in DR site selection means placing the recovery site far enough from the primary site so that a regional disaster (hurricane, earthquake, flood) will not affect both simultaneously.
Which statement BEST describes the relationship between RTO and the cost of a DR solution?
Answer: Lower RTO generally requires greater investment in faster, always-ready recovery infrastructure
A shorter RTO demands more expensive solutions such as hot sites, synchronous replication, and pre-provisioned infrastructure, because the systems must be ready to take over with minimal delay.
A company's DR plan has not been updated in 18 months during which they migrated to a new ERP system. What is the MOST significant risk?
Answer: Recovery procedures may reference systems and processes that no longer exist, causing recovery failure
An outdated DR plan risks recovery failure because procedures, system dependencies, and contact information may no longer reflect the actual IT environment after major changes like an ERP migration.
Which metric measures the percentage of time a system is operational and available over a given period?
Answer: Availability (uptime percentage)
System availability, expressed as a percentage (e.g., 99.9% uptime), measures how often a system is operational during a defined period and is a key SLA metric in DR planning.
What is the PRIMARY benefit of storing DR plan documentation in an offsite, cloud-accessible location?
Answer: It ensures recovery teams can access the plan even if the primary site and its documentation are destroyed
Storing DR plans offsite or in the cloud ensures that if the primary site is destroyed in a disaster, recovery teams can still access the documentation they need to execute the recovery.
