Deallocate the virtual machine. Delete the virtual machine. Implement Privileged Identity Management. Resize the virtual machine. Next

Deallocate the virtual machine If you have virtual machine workloads that are used only during certain periods, but you run them every hour of every day, then you are wasting money. These virtual machines are great candidates to deallocate when not in use and start back when required to save compute costs while the virtual machines are deallocated.

Which Azure Blob storage service tier has the highest storage costs and the fastest access times for reading and writing data? Archive Cool Hot

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 type of strategy uses a series of mechanisms to slow the advancement of an attack that aims to gain unauthorized access to data? defense in depth distributed denial-of-service (DDoS) least privileged access perimeter

defense in depth A defense in depth strategy uses a series of mechanisms to slow the advancement of an attack that aims to gain unauthorized access to data. The principle of least privilege means restricting access to information to only the level that users need to perform their work. A DDoS attack attempts to overwhelm and exhaust an application's resources. The perimeter layer is about protecting an organization's resources from network-based attacks.

Select the answer that correctly completes the sentence. An example of [answer choice] is automatically scaling an application to ensure that the application has the resources needed to meet customer demands. agility elasticity geo-distribution high availability

elasticity Elasticity refers to the ability to scale resources as needed, such as during business hours, to ensure that an application can keep up with demand, and then reducing the available resources during off-peak hours. Agility refers to the ability to deploy new applications and services quickly. High availability refers to the ability to ensure that a service or application remains available in the event of a failure. Geo-distribution makes a service or application available in multiple geographic locations that are typically close to your users.

management groups Management groups can be used in environments that have multiple subscriptions to streamline the application of governance conditions. Resource groups can be used to organize Azure resources. Administrative units are used to delegate the administration of Azure AD resources, such as users and groups. Accounts are used to provide access to resources

Which cloud service model is used by Azure SQL Database? Infrastructure as a service (IaaS) platform as a service (PaaS) software as a service (SaaS)

platform as a service (PaaS)

Your organization is building a custom application. You need to focus on application development rather than configuration and management of servers. Which cloud service model should you use? Select only one answer. infrastructure as a service (IaaS) platform as a service (PaaS) software as a service (SaaS)

platform as a service (PaaS) With PaaS, users can focus on application development because the cloud provider handles all the platform management. In SaaS, the cloud provider manages all aspects of the application environment, such as virtual machines, networking resources, data storage, and applications. IaaS is the closest service model to managing physical servers.

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

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. Deleting or deallocating a resource means that you will no longer be billed for it. Different regions can have different associated prices. Resources cost the same no matter the time of day or the day of the week.

To which object or level is an Azure role-based access control (RBAC) role applied? Select only one answer. policy resource lock resource tag scope

scope An Azure RBAC role is applied to a scope, which is a resource or set of resources that the access applies to. Resource locks prevent the accidental change or deletion of a resource. Resource tags are used to locate and act on resources associated with specific workloads, environments, business units, and owners. Policies enforce different rules across resource configurations so that the configurations stay compliant with corporate standards.

Which type of cloud service model is typically licensed through a monthly or annual subscription? Infrastructure as a service (IaaS) platform as a service (PaaS) software as a service (SaaS)

software as a service (SaaS) SaaS is software that is centrally hosted and managed for you and your users or customers. Usually, one version of the application is used for all customers, and it is licensed through a monthly or annual subscription. PaaS and IaaS use a consumption-based model, so you only pay for what you use.

What is high availability in a public cloud environment dependent on? capital expenditures Cloud-based backup retention limits the service-level agreement (SLA) that you choose the vertical scalability of an app

the service-level agreement (SLA) that you choose Different services have different SLAs. Sometimes different tiers of the same service will offer different SLAs, which can increase or decrease the promised availability.

Select the answer that correctly completes the sentence. Increasing compute capacity for an app by adding RAM or CPUs to a virtual machine is called [answer choice]. disaster recovery high availability horizontal scaling vertical scaling

vertical scaling You scale vertically to increase compute capacity by adding RAM or CPUs to a virtual machine. Scaling horizontally increases compute capacity by adding instances of resources, such as adding virtual machines to the configuration. Disaster recovery keeps data and other assets safe in the event of a disaster. High availability minimizes downtime when things go wrong.
