CASE STUDY: MediSecure Overview: Telehealth provider, 1500 employees, $300M revenue. Core app on AWS, 3 acquired clinics on VMware, fragmented EHRs, Active Directory. Business Req: Unify patient records, integrate clinics in 90 days, launch patient portal. Execs: CEO wants rapid integration; CFO wants CapEx to OpEx; CISO demands strict HIPAA/GDPR compliance. Tech Req: End-to-end PHI encryption, comprehensive audit logging, hybrid connectivity to clinics, DR (RPO 5m, RTO 1h). Constraints: Clinics have low bandwidth, high staff turnover requires automated IAM, legacy EHRs cannot be modified immediately. QUESTION: Which database architecture meets the Disaster Recovery requirements of RPO 5 minutes and RTO 1 hour for the unified patient portal?
Your SRE team wants to implement Chaos Engineering to test the resilience of a microservices application running on GKE. Which THREE actions represent valid chaos engineering experiments in GCP? (Select THREE)
CASE STUDY: ManuIoT Overview: Industry: Manufacturing Size: 100 factories globally Environment: - 100,000 sensors - Local SCADA - Fragmented SQL Server DBs - No central analytics Requirements: - Predictive maintenance - Real-time global dashboards - Edge computing Exec Statements: - CEO: Monetize telemetry. - CFO: Costs must scale linearly. - VP Ops: Factory lines need local control if internet drops. Tech Reqs: - Ingest 1M msgs/sec - Stream processing - Offline factory capabilities - Train ML centrally, deploy to edge Constraints: - Low bandwidth/high latency at factories - Legacy MQTT protocol - Zero IT staff at factories QUESTION: To satisfy the VP of Operations' requirement for offline factory capabilities and local control, which solution should you deploy at the factories?
Your company is designing a disaster recovery (DR) plan for a critical application. The business requirements state a Recovery Time Objective (RTO) of 15 minutes and a Recovery Point Objective (RPO) of 5 minutes. Which DR architecture should you implement?
CASE STUDY: ShopGlobal Company Overview: ShopGlobal is an international e-commerce retailer. They are preparing for their largest annual sales event (Black Friday) and want to migrate off their aging on-premises infrastructure. Current Technical Environment: - 3 on-premises data centers (US-East, US-West, EU-Central). - VMware vSphere environment with 500 VMs. - Monolithic Java application running on Tomcat. - Oracle RAC database for transactions. - 50 TB of product images on SAN storage. Business Requirements: - Ensure 100% availability during the upcoming holiday season. - Modernize the application architecture over the next 3 years. - Reduce capital expenditure (CapEx) by shifting to an OpEx model. Executive Statements: - CEO: "Downtime during Black Friday costs us $1M per hour. We need bulletproof reliability." - CFO: "We want to stop buying hardware. Move everything to a pay-as-you-go model." - CTO: "We want to eventually move to microservices, but we don't have time to rewrite the app before the holidays." Technical Requirements: - Migrate the existing VMs to the cloud with minimal changes initially. - Implement a global CDN for product images to reduce latency. - Set up disaster recovery with an RPO of 15 minutes and RTO of 1 hour. - Ensure PCI-DSS compliance for payment processing. Constraints: - The migration must be completed in 4 months (before the code freeze). - The Oracle database license cannot be easily transferred to the cloud. - The team has no experience with Kubernetes or containers yet. QUESTION: To meet the Disaster Recovery requirements (RPO of 15 minutes, RTO of 1 hour), how should you configure the architecture?
Your organization has adopted Site Reliability Engineering (SRE) practices. The development team wants to push a major new feature to production, but the operations team notes that the application has consumed 110% of its error budget for the current 30-day window due to recent outages. According to SRE principles, what should happen next?
