Why is cloud computing often less expensive than on-premises datacenters? Each correct answer presents a complete solution. Select only one answer. Cloud service offerings have limited functionality. Network bandwidth is free. Services are only offered in a single geographic location. You are only billed for what you use.
Renting compute and storage services and being billed for only what you use often lowers operating expenses. Depending on the service and the type of network bandwidth, charges can be incurred. Cloud service offerings often provide functionality that can be difficult or cost-prohibitive to deploy on-premises, especially for smaller organizations. Major cloud providers offer services around the world. Making it easy and relatively inexpensive to deploy services close to where your users reside.

Increasing the capacity of an application by adding additional virtual machine is called [answer choice]. Select only one answer. agility high availability horizontal scaling vertical scaling
Scaling horizontally increases compute capacity by adding instances of resources, such as adding virtual machines to the configuration. You scale vertically to increase compute capacity by adding RAM or CPUs to a virtual machine. Agility refers to the ability to deploy new applications and services quickly. High availability minimizes downtime when things go wrong.
Which Azure Blob storage service tier has the highest storage costs and the fastest access times for reading and writing data? Select only one answer. Archive Cool Hot
The Hot tier is optimized for storing data that is accessed frequently. The Cool access tier has a slightly lower availability SLA and higher access costs compared to hot data, which are acceptable trade-offs for lower storage costs. Archive storage stores data offline and offers the lowest storage costs, but also the highest costs to rehydrate and access data.
Which two factors affect Azure costs? Each correct answer presents a complete solution. Select all answers that apply. availability zone selection date and time of use resource location resource usage
Usage meters, such as CPU time, disk size, and write operations, are used to calculate your bill for an Azure resource.

What can you use to ensure that a user can only access applications from compliant devices? Select only one answer. Conditional Access hybrid identity multi-factor authentication (MFA) single sign-on (SSO)
Conditional Access is a feature that Microsoft Entra uses to allow or deny access to resources based on identity signals, such as the device being used. SSO enables a user to sign in one time and use that credential to access multiple resources and applications from different providers. MFA is a process whereby a user is prompted during the sign-in process for an additional form of identification. Hybrid identity solutions create a common user identity for authentication and authorization to all resources, regardless of location.
