10 original practice questions · Untimed · Follow each question’s response instructions
1. A parcel company wants dispatchers to test new route-planning features every week. It currently buys servers for each experiment, although most trials are abandoned. The board asks which proposed measure best connects a cloud initiative to this business objective. Assume data controls and service suitability will be evaluated separately.
gcdl-q-0012. A fictional mapping startup limits calls to one Google Cloud API using a rate quota. Storage and other services in the same project continue consuming resources. A founder claims this quota guarantees that the project's total monthly bill stays below a specified currency amount. Which response best evaluates that claim using the purpose of quotas?
gcdl-q-0453. A small design agency needs shared email, calendars, and document editing. It has no requirement for a custom application and no team available to maintain application code or operating systems. It still needs to decide who can access client documents. Which proposal best matches the agency's needs and its remaining responsibility?
gcdl-q-0074. A fictional architecture practice wants early spending visibility for its experimental project without automatically interrupting designers' work. Finance wants a monthly planned amount, notifications to a nominated project manager, and a warning based on forecasted costs before the month ends. Which TWO settings belong in an alerts-only Cloud Billing budget for this requirement? Select exactly TWO.
Select all that apply.
gcdl-q-0465. A fictional ticket distributor has hundreds of partner applications using a stable API. It plans to replace one backend implementation over several releases, but cannot require all partners to update together. An API proxy layer is available for this transition. Which use of that layer best supports backend evolution while preserving the agreed partner-facing interface?
gcdl-q-0356. A manufacturer proposes moving an unstable inventory process unchanged to cloud-hosted virtual machines. Its process still has duplicate product records and no agreed owner for data corrections. Which response best addresses the claim that the move alone will complete its digital transformation?
gcdl-q-0047. An insurer intentionally operates one analytics workload on Google Cloud and a separate business application on another public-cloud provider. Management wants a description of its provider strategy. No connection to privately operated infrastructure is specified. Which statement is best supported?
gcdl-q-0038. An authorized employee resolves the intended service name and completes a permitted network connection. The service then returns an application authorization denial for a reporting operation. Which next investigation follows the demonstrated failure boundary?
gcdl-q-0539. A regional ticketing service has chosen a Google Cloud region that meets its documented location requirements. Its current design places the application and its critical database in one zone. Management now requires the service to remain usable during a single-zone outage; surviving an entire regional outage is outside this project. Which TWO actions directly address and validate this requirement? Select exactly TWO.
Select all that apply.
gcdl-q-00910. A factory already sends sensor messages through Pub/Sub into BigQuery. The messages arrive successfully, but each device reports temperature in its own unit and the dashboard combines them incorrectly. Engineers need managed processing that converts readings into one agreed unit before writing analytical records. Which change targets this defect at the appropriate pipeline stage?
gcdl-q-017Answers & reasoning
1. Measure how quickly a team can provision an experiment, evaluate it with dispatchers, and retire unused resources. · Choice A
The stated objective is a faster learning cycle, not maximum infrastructure consumption. A measure covering provisioning, user evaluation and retirement tests whether teams can experiment and stop paying for unnecessary capacity. Cloud services can support this agility, but a deployment label alone does not demonstrate business value. Cost, access and reliability still need their own evidence; this measure makes no automatic claim about them.
gcdl-q-0012. The quota restricts that API's consumption, so total spending still needs separate cost controls. · Choice A
A rate quota restricts how much of a particular resource can be consumed over a time period. It can block requests that exceed the allowed consumption, but its unit and scope are not the project's aggregate currency bill. Storage and other services continue to create charges in this scenario. The founder should assess costs and suitable controls across the actual services instead of treating one API quota as a universal financial limit.
gcdl-q-0453. Adopt a SaaS collaboration suite and administer user access and stored client data. · Choice A
The agency wants a finished collaboration application rather than a platform for developing or installing one. SaaS supplies the application and transfers more of the supporting operational work to the service provider, fitting the absence of a development or operating system team. That responsibility shift does not decide which employees may view client documents. The customer still administers access controls and the data it places in the service. The appropriate proposal combines a finished service with deliberate customer access management.
gcdl-q-0074. Scope the budget to the experimental project and set its monthly planned amount.; Configure a forecasted-cost threshold and a notification channel reaching the project manager.
Translate the request into budget scope, period, amount and notification behavior. An alerts-only budget can cover a specific project, use a monthly planned amount, and alert when forecasted costs cross a selected percentage. A suitable notification channel can reach the nominated project manager. These settings give visibility without the automatic interruption the scenario excludes. A rate quota addresses a particular resource's consumption, while disabling billing or selecting a spend-cap intervention changes the requested operating behavior.
gcdl-q-0465. Keep the partner interface stable and route its requests through Apigee to the changing backend. · Choice C
The constraint is independent partner release schedules, so the integration boundary must remain stable while the implementation changes. Apigee proxies can isolate API consumers from backend changes and provide a consistent interface. The team must still implement and test compatible behavior behind that interface; merely adding a proxy cannot repair a breaking contract automatically. Direct backend coupling or a mandatory simultaneous cutover transfers the backend release schedule to partners, contradicting the scenario.
gcdl-q-0356. Treat the infrastructure move as one component, and assign data ownership and process improvements alongside measurable business goals. · Choice D
Changing the hosting location can support transformation but cannot settle an unresolved business process or determine authoritative product data. The proposal needs accountable people, process changes and measures of inventory quality as well as suitable technology. This answer preserves the possible value of migration while addressing the exact defects that the stem says will remain after the move.
gcdl-q-0047. It uses a multicloud strategy because workloads run on more than one cloud provider. · Choice C
Using more than one cloud provider supports the multicloud description. It does not by itself prove portability, resilience or freedom from proprietary dependencies. Those outcomes require examining application interfaces, data formats, operating procedures and staff capabilities. The question deliberately distinguishes describing an existing strategy from claiming benefits that have not been tested.
gcdl-q-0038. Identify the application principal and the permission required for the reporting operation. · Choice D
The observations establish name resolution and a network connection for the tested client. They do not establish permission to perform every application operation. An authorization denial calls for checking which principal the application sees and what permission that operation requires. A connection can be healthy while a particular action is intentionally forbidden. The IAM principle is principal, action and resource; any fix should preserve least privilege rather than granting broad access to remove an error.
gcdl-q-0539. Distribute the application and its critical data dependencies across separate zones with failover.; Simulate a zone outage and verify that the service continues through its failover path.
Treat a zone as a failure domain and trace every critical dependency. A second application copy cannot preserve service if both copies or their only database depend on the failed zone. Placement and data availability must therefore support operation across separate zones. The design must also be exercised. Simulating a zone outage checks that traffic and dependencies actually move to a working path. These actions target the specified zonal event; they do not establish protection against loss of the whole region, which would need a separate recovery design.
gcdl-q-00910. Add a Dataflow transformation between message ingestion and BigQuery output. · Choice A
The defect is not that events fail to arrive or that dashboards refresh too slowly. It is that comparable measurements are represented in incompatible units. The pipeline needs an explicit transformation implementing the agreed conversion before the analytical records are written. Dataflow reads from sources, transforms data, and writes to destinations, including the documented Pub/Sub-to-BigQuery pattern. Engineers must define and test the conversion itself; a managed processing service does not decide business semantics. Retention, dataset relocation, and refresh frequency preserve the same incorrect values if no conversion is added.
