Question 1:
In the infrastructure as a service (laaS) cloud service model, which two components are the responsibility of the cloud service provider? Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.
A. the configuration and maintenance of storage
B. the installation and configuration of the operating system
C. maintaining the hardware
D. the network configuration
E. physical security of the datacenter infrastructure
Correct Answer: CE
Infrastructure as a service (IaaS) is a type of cloud computing service that offers essential compute, storage, and networking resources on demand, on a pay-as-you-go basis. IaaS is one of the four types of cloud services, along with software as a service (SaaS), platform as a service (PaaS), and serverless.
Migrating your organization\’s infrastructure to an IaaS solution helps you reduce maintenance of on-premises data centers, save money on hardware costs, and gain real-time business insights. IaaS solutions give you the flexibility to scale your IT resources up and down with demand. They also help you quickly provision new applications and increase the reliability of your underlying infrastructure.
IaaS lets you bypass the cost and complexity of buying and managing physical servers and datacenter infrastructure. Each resource is offered as a separate service component, and you only pay for a particular resource for as long as you need it. A cloud computing service provider like Azure manages the infrastructure, while you purchase, install, configure, and manage your own software – including operating systems, middleware, and applications.

Correct Answer:
Explanation:
Azure Arc simplifies governance and management by delivering a consistent multi-cloud and on-premises management platform.
Azure Arc provides a centralized, unified way to:
Manage your entire environment together by projecting your existing non-Azure and/or on-premises resources into Azure Resource Manager.
Manage virtual machines, Kubernetes clusters, and databases as if they are running in Azure.
Etc.
Incorrect:
*
Why use Azure AD Connect?
Integrating your on-premises directories with Azure AD makes your users more productive by providing a common identity for accessing both cloud and on-premises resources. Users and organizations can take advantage of:
Users can use a single identity to access on-premises applications and cloud services such as Microsoft 365.
Single tool to provide an easy deployment experience for synchronization and sign-in.
Provides the newest capabilities for your scenarios. Azure AD Connect replaces older versions of identity integration tools such as DirSync and Azure AD Sync.

VPN Gateway sends encrypted traffic between an Azure virtual network and an on-premises location over the public Internet. You can also use VPN Gateway to send encrypted traffic between Azure virtual networks over the Microsoft network. A VPN gateway is a specific type of virtual network gateway.

Pipeline agent is machine where your build is performed. An agent is installable software that runs one job at a time. Agent job is a set of steps which is recognized as execution boundary. Each job runs on an agent. All of the steps run together on the same agent.

Question 3:
Note: The question is included in a number of questions that depicts the identical set-up. However, every question has a distinctive result. Establish if the solution satisfies the requirements.
You are currently trying to generate a number of managed Microsoft SQL Server instances in an Azure environment. During the process, you are presented with a notification informing you that the Azure subscription limits must be increased.
You want to make sure that you can complete your task.
Solution: You generate a service health alert.
Does the solution meet the goal?
A. Yes
B. No
Correct Answer: B
Question 4:
You need to identify the type of failure for which an Azure availability zone can be used to protect access to Azure services. What should you identify?
A. a physical server failure
B. an Azure region failure
C. a storage failure
D. an Azure data center failure
Correct Answer: D
Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. An Availability Zone is a physically separate zone, within an Azure region. There are three Availability Zones per supported Azure region.
Each Availability Zone has a distinct power source, network, and cooling. By architecting your solutions to use replicated VMs in zones, you can protect your apps and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone.

Question 10:
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while
others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You plan to deploy several Azure virtual machines.
You need to ensure that the services running on the virtual machines are available if a single data center fails.
Solution: You deploy the virtual machines to two or more resource groups.
Does this meet the goal?
A. Yes
B. No
Correct Answer: B
A resource group is a logical container for Azure resources. When you create a resource group, you specify which location to create the resource group in. However, when you create a virtual machine and place it in the resource group, the virtual machine can still be in a different location (different datacenter). Therefore, creating multiple resource groups, even if they are in separate datacenters does not ensure that the services running on the virtual machines are available if a single data center fails.

Question 11:
To which cloud models can you deploy physical servers?
A. private cloud and hybrid cloud only
B. private cloud only
C. private cloud, hybrid cloud and public cloud
D. hybrid cloud only
Correct Answer: A
A private cloud is on-premises so you can deploy physical servers.
A hybrid cloud is a mix of on-premise and public cloud resources. You can deploy physical servers on-premises.

Question 12:
What is guaranteed in an Azure Service Level Agreement (SLA) for virtual machines?
A. uptime
B. feature availability
C. bandwidth
D. performance
Correct Answer: A
The SLA for virtual machines guarantees ‘uptime’. The amount of uptime guaranteed depends on factors such as whether the VMs are in an availability set or availability zone if there is more than one VM, the distribution of the VMs if there is more than one or the disk type if it is a single VM.
The SLA for Virtual Machines states:
1.
For all Virtual Machines that have two or more instances deployed across two or more Availability Zones in the same Azure region, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.99% of the time.
2.
For all Virtual Machines that have two or more instances deployed in the same Availability Set or in the same Dedicated Host Group, we guarantee you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the time.
3.
For any Single Instance Virtual Machine using Premium SSD or Ultra Disk for all Operating System Disks and Data Disks, we guarantee you will have Virtual Machine Connectivity of at least 99.9%.

A. an Azure web app
B. an Azure virtual machine
C. an Azure logic app

Your company deploys several virtual machines on-premises and to Azure. ExpressRoute is deployed and configured for on-premises to Azure connectivity.
Several virtual machines exhibit network connectivity issues.
You need to analyze the network traffic to identify whether packets are being allowed or denied to the virtual machines.
Solution: Use Azure Advisor to analyze the network traffic.
Does this meet the goal?
A. Yes
B. No
Correct Answer: B
Instead use Azure Network Watcher IP Flow Verify, which allows you to detect traffic filtering issues at a VM level.
Note: IP flow verify checks if a packet is allowed or denied to or from a virtual machine. The information consists of direction, protocol, local IP, remote IP, local port, and remote port. If the packet is denied by a security group, the name of the
rule that denied the packet is returned. While any source or destination IP can be chosen, IP flow verify helps
administrators quickly diagnose connectivity issues from or to the internet and from or to the on-premises environment.
