Study ISC2 CISSP Recovery and Resilience: key concepts, common traps, and exam decision cues.
On this page
Recovery questions are usually about matching resilience investment to business need. CISSP wants you to connect BIA results, RTO/RPO targets, backup strategy, site design, and physical protections into one coherent operating model.
Resilience-choice map
Requirement
Better first instinct
restore a critical service very quickly
tighter recovery architecture and more ready standby capability
protect against data loss
backup and replication choices aligned to RPO
keep facilities and people safe
layered physical and environmental controls
survive disruption over time
continuity and DR planning validated by exercises
What the exam is really testing
If the stem says…
Strong reading
“mission critical”
recovery objectives should drive architecture cost and readiness
“backup exists”
the real question is whether restoration meets the objective
“facility threat”
physical security and safety controls are part of operations, not an afterthought
Decision order that usually wins
Start with business impact and recovery objectives.
Decide whether the issue is time to restore, data-loss tolerance, facility safety, or operating continuity.
Match backup, replication, and standby design to RTO and RPO.
Include physical, environmental, utility, and personnel dependencies.
Validate the whole recovery model through exercises, not assumptions.
These questions reward proportional design. CISSP does not want the fanciest recovery site by default. It wants a design that satisfies business need and is actually testable.
Scenario triage
Scenario
Better first move
outage tolerance is measured in minutes
use more ready standby capability aligned to RTO
data loss tolerance is minimal
improve replication and backup strategy aligned to RPO
backups exist but recovery is uncertain
test restoration against objectives
facility hazard threatens people or operations
apply physical and environmental safeguards
resilience plan looks complete on paper only
run exercises and validate assumptions
Common traps
Trap
Better rule
treating backups as proof of recoverability
recovery must be tested against objectives
choosing the most expensive site model without checking business need
match the site choice to impact and recovery targets
ignoring people, facilities, or utilities in resilience planning
operational resilience is broader than servers alone
