A few cards from the deck
What is cloud computing?
Show the answer
The delivery of computing services (compute, storage, networking, databases, analytics...) over the internet, on demand, with pay-as-you-go pricing.
The provider owns and operates the physical infrastructure. The customer consumes resources when needed, without buying or maintaining hardware, and pays only for what they use.
Which of the following factors does NOT affect the cost of an Azure resource?
- Outbound network traffic
- The deployment region
- The number of tabs open in the Azure portal
- The resource type and size
Show the answer
The number of tabs open in the Azure portal
Cost depends on factors such as resource type, consumption, region, network traffic, subscription type, Marketplace purchases and maintenance. Using the portal isn't billed.
As you move from IaaS to PaaS to SaaS, the share of responsibility held by the … increases.
Show the answer
As you move from IaaS to PaaS to SaaS, the share of responsibility held by the cloud provider increases.
With IaaS, the customer manages the OS, middleware and applications. With PaaS, the provider also manages the OS and runtime. With SaaS, the provider manages almost everything except data, identities and devices.
What is an Azure region?
Show the answer
A geographical area that contains one or more nearby datacenters connected by a low-latency network.
You choose the region for each resource. That choice affects latency, service availability, compliance (data residency) and price.
Which of the following criteria does NOT influence the choice of an Azure region?
- The color of the Azure portal theme
- Data residency requirements
- Proximity to users
- Availability of the required service in the region
Show the answer
The color of the Azure portal theme
Not every service is available everywhere, latency depends on distance to users, and regulations may require a specific country. Prices also vary from one region to another.
An Azure region that supports availability zones has a minimum of … of them.
Show the answer
An Azure region that supports availability zones has a minimum of three of them.
This minimum of three zones makes it possible to spread redundant resources and survive the loss of an entire zone.
