Security wants sign-ins from the office network to proceed normally, sign-ins from anywhere else to require a second factor, and any sign-in to the finance application from an unmanaged device to be refused outright. Which capability expresses all three rules?

Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
The options
Correct Conditional Access policies
Correct. Conditional Access evaluates signals at sign-in — the user, the location, the state of the device, the application being reached, the assessed risk — and applies a decision: allow, allow with extra requirements, or block.
Not correct Azure role-based access control assignments
Wrong. Role assignments decide what an already-authenticated principal may do to Azure resources. They have no visibility of where a sign-in came from or what device it used.
Not correct Turning on multifactor authentication for everybody, everywhere, always
Wrong. It satisfies one clause by ignoring the other two: office sign-ins get prompted anyway, and the finance application is still reachable from an unmanaged device. Blanket rules are what signal-based policies replace.
Not correct Resource locks on the finance application's resources
Wrong. A lock prevents a resource being deleted or modified by administrators. It cannot refuse a user's sign-in, which is what two of the three rules require.
Why
Conditional Access is the if-then layer of identity: if these signals hold, then require this or block. It is what makes multifactor authentication proportionate rather than constant, and it is where device state, location and risk enter the decision. Remember the division of labour — Conditional Access decides whether you get in and on what terms, role-based access control decides what you can touch once you are.

- An image-resizing routine runs for about two seconds whenever a file lands in a storage container — perhaps two hundred times on a busy day, and not at all on a quiet one. The team wants to pay for the work done and maintain no servers. Which compute option fits? machine-checked
- A fifteen-year-old accounting application needs a kernel-level driver, a scheduled task that edits the registry, and a runtime version nobody supports any more. The business wants it running in Azure this quarter with as few code changes as possible. Where does it go? machine-checked
- A team runs nine small services, each with its own conflicting library versions. They want each one packaged with its dependencies, starting in seconds, several to a host, without a separate operating system per service. Which compute type are they describing? machine-checked
- Which TWO of these statements about Azure compute types are true? machine-checked
- A public website runs on four identical virtual machines behind a load balancer. Traffic triples while a television advert airs and falls back an hour later. The team wants instances added and removed automatically against CPU, all built from one image, with nobody clicking. Which option is designed for that? machine-checked
- Three virtual machines form a quorum-based cluster in a region that has no availability zones. You want them placed so that neither a single rack losing power nor a single batch of planned host maintenance can take all three at once. What do you configure? machine-checked
