Answer everything, then click Check: your score and explanations will appear.
5.1 · Recall
1. What do we first seek to reduce in operational cybersecurity on the IT side?
Fewer exposed services, unnecessary software and privileged accounts reduce the attack surface: it is the founding principle.
5.2 · Recall
2. What does the RTO of a disaster recovery plan measure?
RTO = maximum recovery time; RPO = tolerable data loss. These are the two benchmarks that size the plan.
5.3 · Recall
3. In ITIL, what is a “problem”?
An incident is a one-off interruption to resolve fast; a problem is the root cause of recurring incidents, to address in depth.
5.4 · Recall
4. Why is documenting IT procedures a continuity issue?
Knowledge that exists only in one head stalls the business in case of absence: documentation makes it shared, reusable and actionable.
5.1 · Application
5. Sofiane discovers a service exposed on the Internet, not updated for months. What does he do first?
Known flaws are actively scanned: you patch after a pilot test, rather than leaving the door open.
5.2 · Application
6. Sofiane wants the payroll service to tolerate very little data loss. Which benchmark does that concern?
RPO measures tolerable data loss: the less you accept, the more frequent backups must be.
5.3 · Application
7. Sofiane sees the same printer go down every Monday morning. What does he do according to ITIL?
Restarting fixes the incident of the moment; looking for the root cause (the problem) stops the recurrence.
5.5 · Application
8. Sofiane targets cloud administration. Which certification path is realistic?
You progress in tiers: fundamentals to frame things, then a more operational associate, practicing in parallel.
5.1 · Arbitration
9. The SME hesitates between stacking every tool or reducing the attack surface. Which choice is healthier?
You first close the unnecessary (attack surface) then stack layers that serve: that is defense in depth.
5.2 · Arbitration
10. Management hesitates to fund a DRP. Which argument is most convincing?
Comparing the cost of an interruption to the cost of the plan and translating needs into RTO/RPO makes the investment concrete.
5.4 · Arbitration
11. Sofiane, the only one who knows a manipulation, must go on leave. What useful thing does he do before?
A tested runbook makes the team autonomous and reduces dependence on a single person: that is the spirit of documentation.
5.5 · Arbitration
12. A colleague of Sofiane wants to specialize in security. What advice does he give?
You choose a path and progress in tiers, practicing in parallel: skill matters more than the badge.
What's next?
Score ≥ 80%: you master the fundamentals of security and professional development — put them into practice on Sofiane's real fleet.
Score between 50% and 80%: go back over the section(s) you missed (5.1 cybersecurity, 5.2 backup/DRP, 5.3 fleet/ITSM, 5.4 documentation, 5.5 specialization), reread the course, then retake the test.
Score < 50%: reread the whole level 5 while applying each 48h challenge (workstation review, DRP sketch, inventory and tickets, tested runbook, specialization journey) before trying again.
And after that? Keep Sofiane's reflexes — harden, patch, back up, document, specialize: they are what moves a support technician toward administration and security.
