• A university research group and the city open-data office jointly fund a shared environment for civic datasets, with shared governance and a common compliance posture. Which cloud deployment model best fits this arrangement?
• After a ransomware event, the city keeps identity services on-premises but rebuilds citizen-facing apps in public cloud at the same time. Which deployment model describes this split of responsibilities?
• A new municipal portal version runs in parallel environment B while production traffic stays on environment A until cutover; rollback means flipping traffic back to A. Which deployment strategy is this?
• Only 5% of citizens should see the new UI first while metrics are watched before a wider rollout. Which deployment strategy matches this plan?
• City permit API instances are upgraded a few at a time so the service never goes fully dark. Which deployment strategy is being used?
• A tiny utility VM is upgraded on the same instance during a maintenance window with brief downtime accepted. Which deployment strategy fits this approach?
• Rollback must be near-instant after a bad release without rebuilding every server from scratch. Which strategy best supports that requirement?
• A risk-averse city council wants limited blast radius on day one of a citizen portal redesign. Which deployment strategy best minimizes initial user exposure?
• Capacity is tight and running two full production stacks for blue-green is too expensive for the parks reservation API. Which deployment approach is most appropriate?
• Health checks fail mid-rollout on the tax-payment API. What should the team do regarding the rolling wave?
• A stateful network appliance used for city VPN aggregation cannot easily run two versions side by side. Which deployment strategy is most realistic for its upgrade?
• Feature flags plus a tiny traffic slice will validate a payments change before citywide enablement. Which deployment strategy does this describe?
• After green proves healthy for the licensing portal, blue is kept briefly as instant rollback capacity and then recycled. Which practice does this describe?
• Ops confuses a canary (small user percentage) with blue-green (full parallel environment switch). What is the key distinction?
• A basement datacenter permitting app is moved into public cloud VMs with minimal redesign. Which migration direction does this represent?
• A SaaS trial ends and the city must bring data and processing back into its own datacenter. Which migration type is this?
• Workloads move from Provider A to Provider B after a municipal contract change. Which migration type is this?
• The city lifts permitting VMs to cloud IaaS with almost no code change to exit aging hardware quickly. Which migration strategy is this?
• The inspection app keeps most of its code but swaps self-managed MySQL for a provider-managed database. Which migration strategy best describes this?
• A monolith for citizen casework is redesigned into microservices and managed services to gain cloud-native scalability. Which migration strategy is this?
• A rarely used legacy license server stays on-premises for now during the cloud migration program. Which 6 R-style decision is this?
• An unused departmental Access application is shut down instead of migrated. Which migration strategy decision is this?
• Code is reworked to use cloud APIs and eventing while preserving external behavior for the grants portal. Which migration strategy is this?
• Before moving the records-management workload, teams size CPU, RAM, and disk so cloud resources match the workload profile. Which migration consideration is this?
• Large historical archives may need offline appliance shipping rather than weeks of thin WAN upload during the city's cloud migration. Which migration consideration does this highlight?
• A city's legacy permitting app still requires an OS build the target cloud marketplace images no longer offer cleanly. What migration consideration does this primarily highlight?
• A county evaluates leaving a niche PaaS that stores case files in proprietary export formats. What migration risk should planners emphasize?
• Citizen PII for a municipal benefits system must remain in-country, and several destination regions fail that rule. What migration constraint is this?
• A city plans to exit its on-premises datacenter as part of a cloud migration business case. Besides application hosting, which facilities consideration should finance include?
• Municipal cloud ops wants networks, VMs, and load balancers declared once and applied the same way every time. Which approach best meets that need?
• Ops wants OS packages, services, and config files on city VMs installed identically every time. Which practice fits best?
• A deployment script sets the cloud region from a variable and creates a NAT gateway only when a flag is true. What scripting concepts does this demonstrate?
• Cloud engineers wrap tagging standards in reusable functions so every municipal stack applies the same labels. Why does that modularity help?
• Two staging and production environments for a city portal are created from the same template and should match aside from parameters. Which IaC benefit is being pursued?
• Someone changed a security group in the cloud console for a city API. Automation must notice the live setup no longer matches the desired code. What capability is needed?
• A municipality stores infrastructure templates in Git so every change is reviewed and can be rolled back. What practice does this illustrate?
• A city pipeline validates infrastructure templates in a sandbox before any production apply. What is the primary goal?
• Runbooks explain how deployment parameters map to each municipal environment for the next on-call engineer. Why keep that documentation with the automation?
• A deployment definition for city cloud resources is stored as nested key/value text that many cloud APIs accept natively. Which common format is described?
• Ops prefers indentation-based, human-friendly templates for Kubernetes manifests and many automation tools in the city platform. Which format fits that preference?
• An engineer hotfixes a city load balancer in the console, then the next pipeline run overwrites the change. What lesson should the team reinforce?
• Police video evidence needs multi-petabyte capacity with infrequent retrieval after about 90 days. Which provisioning choice best matches those requirements?
• A municipal OLTP database requires disks with guaranteed high IOPS and low latency. What should provisioning emphasize?
• Citizen PII volumes for a benefits app must use encryption and must not be reachable over the public internet. What should provisioning enforce?
• A seasonal park reservation system must minimize idle cost between tourist peaks. Which provisioning approach best fits?
• The voting results API SLA requires survival of an availability-zone failure. How should resources be provisioned?
• A city recreation portal will process cardholder data and must land in architectures and controls suited to that obligation. What drives the provisioning choices?
• A latency-sensitive CAD integration between city design systems needs private connectivity and carefully sized bandwidth. What network provisioning focus is required?
• Batch map rendering needs many short-lived vCPUs, while an interactive GIS desktop needs fewer stronger cores or GPU-class instances. What compute provisioning principle applies?
• Architects face cheapest archive storage versus a mandate for sub-second retrieval on the same dataset. What should they do?
• A county cloud team must provision storage, compute, networking, and security controls for a new permit portal, but architects keep skipping categories until after click-ops begin. What approach best maps business requirement categories to concrete resource choices before anyone creates resources?
