Partly checked. None of the 45 questions here has been read against the cited source by a person. 45 questions have been checked against their cited clause by an automated pass — which is not the same thing, and is not a signature.
Only questions a person has signed for are used in mock exams here. That is the whole difference between the two kinds of checking above.
What this objective covers
The 45 questions written for this objective cite 4 Microsoft AZ-900 study guide skill areas (architecture-and-services.compute-and-networking, architecture-and-services.core-architectural-components, architecture-and-services.identity-access-security, architecture-and-services.storage).
They break down as 39 single-answer questions, 4 choose-several questions and 2 type-the-answer questions.
Questions on this objective (page 1 of 3)
- 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
- You are creating your first Azure virtual machine and want to know what it genuinely requires alongside it. Which statement is correct? machine-checked
- Two hundred seasonal contractors need a standard Windows desktop with the company's line-of-business applications, reached from their own unmanaged laptops, for four months. IT insists no company data ends up on those laptops. Which Azure service is built for this? machine-checked
- A web API written in a supported framework must be online next week. The team wants managed HTTPS, scaling out on demand, a way to warm up a new build and swap it into production, and no operating system to patch. Which hosting option is the natural fit? machine-checked
- A containerised platform has grown to thirty services that must be scheduled across nodes, restarted automatically when they fail, upgraded without downtime, and able to find each other by name. Which hosting option matches that list? machine-checked
- A governance review asks, for each hosting option in use, who is responsible for patching the guest operating system. Which statement is accurate? machine-checked
- Two virtual networks in the same region, owned by two different subscriptions, must exchange traffic privately at low latency. The team does not want to deploy or pay for gateways and does not want the traffic on the public internet. What do you configure? machine-checked
- You are dividing a virtual network with the address space 10.10.0.0/16 into subnets for a web tier, an application tier and a database tier. Which statement about that is correct? machine-checked
- Your company owns a domain name through an external registrar and wants Azure to answer public DNS queries for it, managed with the same tooling and role assignments as the rest of the estate. What does Azure DNS do here, and what does it not do? machine-checked
- Which TWO of these statements about virtual network peering are true? machine-checked
- A bank moves tens of terabytes a day between its own datacentre and Azure. It needs predictable throughput, and its regulator objects to that traffic crossing the public internet at all. Which connectivity option should it buy? machine-checked
- A developer working from home occasionally needs to reach a database that has only a private IP address inside an Azure virtual network. There is no VPN device at the developer's end and no office network to connect. What is the appropriate answer? machine-checked
- A storage account must be reachable from your virtual network and nowhere else, addressed by a private IP from your own address space so that on-premises staff reach it through the existing VPN. What do you configure? machine-checked
- An auditor asks whether the traffic flowing over your ExpressRoute circuit is encrypted. What is the accurate answer? machine-checked
- A payment API must keep serving requests if one datacentre in its Azure region loses power. Legal advice is that the data may not leave the region. Which arrangement satisfies both constraints? machine-checked
