Before moving four hundred on-premises servers, leadership wants an inventory, a view of which servers depend on which, an Azure sizing estimate and a projected monthly cost — and then a way to actually carry the migrations out. Which service is built for that whole arc?

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 Azure Migrate
Correct. It is the hub for discovery and dependency analysis, for assessments that produce sizing and cost estimates, and then for performing the migration of servers, databases and web applications.
Not correct Azure Advisor
Wrong. Advisor makes recommendations about resources you already run in Azure. It cannot see four hundred servers sitting in your own datacentre, so it has nothing to assess.
Not correct Azure Data Box
Wrong. Data Box moves bulk data offline. It has no opinion about which virtual machine size a server needs or what the estate will cost per month.
Not correct Azure Arc
Wrong for this question, though it is genuinely adjacent. Arc projects servers running elsewhere into Azure so you can govern and manage them where they are — a decision to keep them, not a plan to move them.
Why
Keep the hybrid tools apart by the verb in the requirement. Migrate assesses and moves. Arc governs what stays where it is. Data Box ships bulk data. Advisor advises on what already runs in Azure. A migration programme usually needs the first, may keep the second for whatever never moves, and reaches for the third only when the data volume defeats the network.

More questions on this objective
- 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
