When creating and placing resources within resource groups there are a few considerations: Each resource must exist in one, and only one, resource group. A resource group can contain resources that reside in different regions. You decide how you want to allocate resources to resource groups based on what makes the most sense for your organization. You can add or remove a resource to a resource group at any time. You can move a resource from one resource group to another. Resources for an application do not need to exist in the same resource group. However, it is recommended that you keep them in the same resource group for ease of management.

What is the service for managing privacy on Azure called? 1. It depends on your subscription level. 2. There isn't a single service, as privacy is part of every service on Azure. 3. Azure Privacy Center. 4. Azure User Safety Portal. 5. Azure Privacy Portal. Ch. 11 ###

There isn't a single service, as privacy is part of every service on Azure. Privacy is a core component of each and every Azure service, so there isn't a single service. All products are built with privacy as a first class citizen.

Resiliency

Resiliency is the ability of a system to recover from failures and continue to function. It's not about avoiding failures, but responding to failures in a way that avoids downtime or data loss. The goal of resiliency is to return the application to a fully functioning state following a failure. High availability and disaster recovery are two crucial components of resiliency.

What are the two types of scaling on Azure? 1. Scaling up or down, and scaling out. 2. Scaling out and scaling across. 3. There is only one type of scaling: scaling up/down. 4. Scale Sets and High Availability

1. Scaling up or down, and scaling out.

Which are factors used to verify a user with multi-factor authentication? Choose 3 1. Something you say. 2. Something you know. 3. Something you can recall quickly. 4. Something you have. 5. Something you feel. 6. Something you are. Ch. 8

2. Something you know. 4. Something you have. 6. Something you are.

What does fault tolerance describe for cloud computing? 1. The ability for multiple regions within Azure to "cover" each other in case of an outage. 2. A complete plan to recover critical business systems and normal operations, in case of a disaster. 3. A system within Azure that uses cloud computing resources to mitigate faults quickly. 4. The resilience of cloud computing to guarantee no downtime.

4. The resilience of cloud computing to guarantee no downtime. Some computing systems require no downtime whatsoever. Using the cloud to leverage fault tolerance can guarantee this. Faults aren't just mitigated quickly, but instantly. Regions covering each other is called geo-redundancy, and recovery plans should always be part of a cloud implementation. Next question

What is an Azure Function? Choose 2 1. A single unit of compute that is triggered by a separate process. 2. A serverless service on Azure. 3. A function to update any resources on Azure. 4. A foundational component of any Azure infrastructure. 5. An add-on to any paid Azure subscription that allows using Azure services as functions in your applications.

1. A single unit of compute that is triggered by a separate process. 2. A serverless service on Azure. Azure Functions are single-task services that can take an input, process it, and then die. It is the first serverless product on Azure. It is a stand-alone product which doesn't rely on other Azure services, although Functions can certainly integrate with them. Functions are available on all subscriptions and are very inexpensive to use.

What is a PowerShell cmdlet? 1. A small lightweight command to perform an action. 2. A lightweight version of PowerShell that can run on mobile devices. 3. A PowerShell scripting language specifically for Azure. 4. An piece of advice from Microsoft about PowerShell updat

1. A small lightweight command to perform an action. Cmdlets make up the majority of Azure features for PowerShell. This makes it easier to be consistent and efficient when interacting with Azure resources. There is no lightweight version of PowerShell and PowerShell works with many different services in Windows.

Tags applied at a resource group level are propagated to resources within the resource group. True False Control and organize Azure resources with Azure Resource Manager

FALSE

Tags can be applied to any type of resource on Azure True False Control and organize Azure resources with Azure Resource Manager

FALSE

Availability Zones are primarily for VMs, managed disks, load balancers, and SQL databases. Azure services that support Availability Zones fall into two categories:

Zonal services - you pin the resource to a specific zone (for example, virtual machines, managed disks, IP addresses) Zone-redundant services - platform replicates automatically across zones (for example, zone-redundant storage, SQL Database).
