| schema:text | A retail bank's card authorisation service is replicated across two data centres. While the network link between them is down, the bank requires that the two sites never approve spending that together exceeds a card's limit. In terms of the CAP theorem, what does this requirement choose, and which processing model fits it? (a) Availability over consistency; BASE, accepting that the remaining limit becomes consistent later; (b) Consistency over availability; ACID, refusing or delaying authorisations that cannot be confirmed; (c) Partition tolerance over both; neither model, since a network partition makes the choice irrelevant; (d) Consistency and availability together; BASE, since replication keeps both during a partition en |

| schema:text | A bank will move its loan database from on-premises servers to a managed cloud database service. According to DAMA-DMBOK2's implementation guidance for data storage and operations, what should come before the move? (a) A readiness and risk assessment (data loss or corruption, technology fit, skills), with the change to how DBAs and developers work planned as part of it; (b) A vendor scorecard only, since a managed service transfers the operational risk to the provider; (c) A one-year freeze on schema changes, so that developers adapt before the DBAs are involved; (d) Nothing beyond a full backup, since a managed service makes a readiness assessment unnecessary en |
