Risk Identification Assessment and Mitigation Questions

Comprehensive practices for proactively identifying, assessing, prioritizing, managing, mitigating, and planning responses to risks across technical, operational, financial, regulatory, security, privacy, and market domains. Candidates should be able to describe methods to surface risks including brainstorming, historical analysis, dependency mapping, scenario analysis, stakeholder interviews, and threat modeling; apply qualitative and quantitative assessment techniques such as probability and impact scoring, risk matrices and heat maps, expected loss calculations, and simulation where appropriate; and use prioritization approaches that reflect risk appetite, tolerance, and cost benefit trade offs. The topic covers selection and design of mitigation options including avoidance, reduction, transfer, and acceptance; preventive, detective, corrective, and compensating controls; layered defense strategies; and domain specific safeguards such as encryption, access controls, logging, data minimization, retention policies, vendor agreements, and incident response planning. It also includes contingency and recovery planning for exposures that cannot be fully mitigated, including defining triggers, contingency actions, owners, contingency budgets and schedule reserves, rollback and fallback strategies, and measurable monitoring indicators. Candidates should be prepared to explain how to create and maintain risk registers, assign owners, monitor and report residual risk, measure control effectiveness over time, align risk activities with architecture and compliance, make trade offs between prevention and contingency, and communicate and escalate risk information to stakeholders and leadership across project and program lifecycles.

Create a plan for a tabletop exercise that validates contingency and recovery plans for a major incident: unauthorized data exfiltration from backups. Include exercise objective(s), scope, participants (engineering, ops, legal, PR, vendors), 3–5 realistic injects, timeline, success metrics, and a post-exercise remediation plan.
MediumSystem Design
53 practiced
Design a layered defense strategy to protect PII across a multi-cloud SaaS platform. Include: data classification, encryption (rest/in-transit/application-level), tokenization/format-preserving techniques, least-privilege and IAM design, logging/alerting, retention minimization, and operational processes (key rotation, access reviews). Explain placement of controls to balance latency and cost.

Define RTO and RPO. For a globally-distributed OLTP customer database, describe a method to determine appropriate RTO and RPO values per service tier and list the architectural choices (replication topologies, backup cadence, region placement) that support those targets, including trade-offs.
HardTechnical
75 practiced
You are advising an engineering team building a payment gateway with a 100ms latency SLO. Evaluate technical and operational controls (e.g., inline TLS termination, HSM-based encryption, WAF, anomaly detection) and propose an optimized control set that meets PCI-DSS requirements while preserving latency. Include testing and measurement strategies to validate both security and performance.
HardSystem Design
61 practiced
Architect an enterprise-scale contingency plan for a catastrophic simultaneous outage affecting multiple regions and data centers (a total-loss scenario). Include:
- Detection triggers and declaration authority- Failover vs degraded-operation strategies- Fallback and rollback procedures- Communication plan (internal/external)- Budget/reserve planning and ownership- RTO/RPO tradeoffs per service tier
Describe governance and runbooks that enable the plan.
