Practice MCQ
An incident is traced to index design and column order. What is the correct fix?
Role practice MCQ for Backend Engineer
Practice MCQAn incident review traces a failure to tool contract design: one tool served both reads and writes behind a mode argument, the agent set the mode to read, and the call committed a write. Which remediation should the Agentic AI Engineer prioritize?

Practice MCQAn internal billing system can tolerate 8 hours of downtime and at most 1 hour of data loss if its primary region is lost. The stack is a stateless application tier over a 400 GB PostgreSQL database, both rebuilt from infrastructure-as-code templates and machine images. Which disaster recovery strategy meets these objectives at the lowest cost?
Role practice MCQ for Cloud Architect
Practice MCQAn online fraud-scoring service must return a decision within 1 s of event ingestion. Bursts of 8× baseline arrive every evening from partner batch exports, inference is capped at 2,400 events/s by a fixed GPU pool, and the next release inserts a message queue between the ingest API and the workers as a hard cutover with no shadow period. Which design should the review approve?

Practice MCQAn SoC pairs an application CPU with an on-chip neural accelerator using zero-copy DMA shared memory. When migrating the design from a hardware-coherent interconnect (ACE/CHI) to a non-coherent interconnect to save area and idle power, what change must the driver software implement to guarantee memory correctness?

Practice MCQAn unattended provisioning agent caused two incidents: a run retried create_record 240 times over 25 minutes before the watchdog killed it with no result; another emitted a record id and reported success while the store held no such record, and billing closed the job. Jobs run unattended at 200/hr, tool calls take 50ms-40s, plans vary per request, and each run must stop within 3 minutes. Which termination design fixes both failures?

Practice MCQComplaints about confidently wrong RAG answers land 10-14 days after the call, and the call itself returned outcome: answered. The provider's request logs expire after 7 days, and the search index is republished nightly so replaying the query the next morning returns different passages. Compliance has cleared keeping call payloads with retrieved document references for 30 days. Which logging design should the team adopt?

Practice MCQDuring fault-tolerant quantum error correction, syndrome extraction circuits take a finite cycle time \(t_\text{cycle}\) consisting of multi-qubit entangling gates, ancilla readout, and state reset. How does \(t_\text{cycle}\) constrain the system relative to physical decoherence times \(T_1\) and \(T_2\)?

Practice MCQThe release gate scores every summary with a single 1–5 quality number. The last two prompt changes each moved it by 0.3, nobody can say which property moved, and the judge model was swapped mid-period. Safety must be able to block the release on its own, verdicts are go/no-go per property, and the team has 200 human ratings a week. Which evaluation design should the team ship before the release in two weeks?
Role practice MCQ for AI Engineer
Practice MCQThe runbook-retrieval assistant logs a similarity score for every query. On a labelled slice of 1,400 production questions, 22% have no answer anywhere in the corpus. The launch gate requires every refusal to be checkable from the request log without asking the model anything, and support wants each refusal to hand the user a concrete next step. How should the team design abstention for the pilot?
