What is the Microsoft Power Platform? Quick overview!
It is a series of integrated tools designed to unlock the potential of other Microsoft applications.
“Microsoft Power Platform” is the general term for three Microsoft products: Power BI, Power Apps and Power Automate, Power Virtual Agent. This Microsoft Power platform merges all data into a common data model. It is a set of products provided by Microsoft to develop and build complex business solutions, analyze and graph data visualization, automate business processes, or build virtual agents for communication.
Power Platform has many exciting possibilities and implications, but it is difficult to know where to start or what it can do for your organization. If you want to learn more about the Power platform, or discuss a potential idea, please contact us today.
Four products provided by the Microsoft Power platform
There are four products:
- POWER BI – used to analyze data from different data sources
- Power Apps – used to build powerful mobile applications for internal use within the organization
- Power Automation – used to design automated workflows to reduce manual tasks.
- Power Virtual Agent – used to develop flexible chatbots that can communicate with external clients
| POWER BI (Overview 2020) | Power BI is a business analysis tool that allows you to easily connect to data sources, create visualizations, and quickly acquire business intelligence. |
| Power Apps (Overview 2020) | Power Apps is a low-code custom application development method that allows users to quickly create applications in a “point and click” manner. Power Apps is more like a service platform provided by Microsoft’s Power platform. This service enables users to quickly build applications that can run on any modern web browser, such as Chrome, Firefox, etc., as well as native mobile applications using Android, IOS, or Windows. |
| Power Automate (Overview 2020) | Power Automate allows you to create automated workflows between Microsoft services or other third-party applications, so that workers can avoid performing repetitive tasks and save valuable time. |
| Power Virtual Agent (Overview 2020) | Power Virtual Agent is a BOT construction service provided by Microsoft for business users. Using it, users can build virtual chat agents from scratch without writing a line of code. All integration and logic can be implemented in the graphical user interface of the Power Virtual Agent portal. |

QUESTION 1
Your company recently deployed a new Active Directory forest named contoso.com. The first domain controller in the forest runs Windows Server 2012 R2.
You need to identify the time-to-live (TTL) value for domain referrals to the NETLOGON and SYSVOL shared folders.
Which tool should you use?
A. Ultrasound
B. Replmon
C. Dfsdiag
D. Frsutil
Correct Answer: C Explanation
Explanation/Reference:
Explanation:
What does DFSDiag do?
dfsdiag /testreferral:
Perform specific tests, depending on the type of referral being used.
* For Sysvol and Netlogon referrals perform the validation for Domain referrals and that it's TTL has the
default value (900s).
Etc.
QUESTION 2
Your network contains two Active Directory forests named contoso.com and adatum.com. Contoso.com contains one domain. Adatum.com contains a child domain named child.adatum.- com.
Contoso.com has a one-way forest trust to adatum.com. Selective authentication is enabled on the forest trust.
Several user accounts are migrated from child.adatum.com to adatum.com. Users report that after the migration, they fail to access resources in contoso.com. The users suc- cessfully accessed the resources in contoso.com before the accounts were migrated.
You need to ensure that the migrated users can access the resources in contoso.com.
What should you do?
A. Replace the existing forest trust with an external trust.
B. Run netdom and specify the /quarantine attribute.
C. Disable SID filtering on the existing forest trust.
D. Disable selective authentication on the existing forest trust.
Correct Answer: C Explanation
Explanation/Reference:
Explanation: Security Considerations for Trusts Need to gain access to the resources in contoso.com
Disabling SID Filter Quarantining on External Trusts Although it reduces the security of your forest (and is therefore not recommended), you can dis- able SID filter quarantining for an external trust by using the Netdom.exe tool. You should con- sider disabling SID filter quarantining only in the following situations:
* Users have been migrated to the trusted domain with their SID histories preserved, and you want to grant
them access to resources in the trusting domain based on the SID history attribute.
Etc.
Incorrect: not B. Enables administrators to manage Active Directory domains and trust relationships from the command prompt, /quarantine Sets or clears the domain quarantine not D. Selective authentication over a forest trust restricts access to only those users in a trusted forest who have been explicitly given authentication permissions to computer objects (resource computers) that reside in the trusting forest
QUESTION 3
Your network contains an Active Directory forest named adatum.com. The forest contains a sin- gle domain. The domain contains four servers. The servers are configured as shown in the fol- lowing table.
You need to update the schema to support a domain controller that will run Windows Server 2012 R2. On which server should you run adprep.exe?
A. Server1
B. DC3
C. DC2
D. DC1 Correct Answer: B
Explanation Explanation/Reference:
Explanation:
Upgrade Domain Controllers to Windows Server 2012 R2 and Windows Server 2012
You can use adprep.exe on domain controllers that run 64-bit versions of Windows Server 2008 or
Windows Server 2008 R2 to upgrade to Windows Server 2012. You cannot upgrade domain controllers
that run Windows Server 2003 or 32-bit versions of Windows Server 2008. To re- place them, install
domain controllers that run a later version of Windows Server in the domain, and then remove the domain
controllers that Windows Server 2003.
QUESTION 4
Your network contains an Active Directory forest named contoso.com. The forest contains three domains. All domain controllers run Windows Server 2012 R2.
The forest has a two-way realm trust to a Kerberos realm named adatum.com.
You discover that users in adatum.com can only access resources in the root domain of contoso.- com.
You need to ensure that the adatum.com users can access the resources in all of the domains in the forest.
What should you do in the forest?
A. Delete the realm trust and create a forest trust.
B. Delete the realm trust and create three external trusts.
C. Modify the incoming realm trust.
D. Modify the outgoing realm trust.
Correct Answer: D Explanation
Explanation/Reference:
*
A one-way, outgoing realm trust allows resources in your Windows Server domain (the do- main that you are logged on to at the time that you run the New Trust Wizard) to be accessed by users in the Kerberos realm.
*
You can establish a realm trust between any non-Windows Kerberos version 5 (V5) realm and an Active Directory domain. This trust relationship allows cross-platform interoperability with security services that are based on other versions of the Kerberos V5 protocol, for example, UNIX and MIT implementations. Realm trusts can switch from nontransitive to transitive and back. Realm trusts can also be either one-way or two-way.

QUESTION 5
Your network contains an Active Directory forest named contoso.com. The forest contains two domains named contoso.com and childl.contoso.com. The domains contain three domain con- trollers.
The domain controllers are configured as shown in the following table.
You need to ensure that the KDC support for claims, compound authentication, and kerberos ar- moring setting is enforced in the child1.contoso.com domain.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Upgrade DC1 to Windows Server 2012 R2.
B. Upgrade DC11 to Windows Server 2012 R2.
C. Raise the domain functional level of childl.contoso.com.
D. Raise the domain functional level of contoso.com.
E. Raise the forest functional level of contoso.com.
Correct Answer: AE Explanation
Explanation/Reference:
Explanation:
The root domain in the forest must be at Windows Server 2012 level. First upgrade DC1 to this level (A),
then raise the contoso.com domain functional level to Windows Server 2012 (E).
* (A) To support resources that use claims-based access control, the principal's domains will need to be running one of the following: / All Windows Server 2012 domain controllers / Sufficient Windows Server 2012 domain controllers to handle all the Windows 8 device au- thentication requests / Sufficient Windows Server 2012 domain controllers to handle all the Windows Server 2012 re- source protocol transition requests to support non-Windows 8 devices

QUESTION 8
Your network contains two Web servers named Server1 and Server2. Both servers run Windows Server
2012 R2.
Server1 and Server2 are nodes in a Network Load Balancing (NLB) cluster. The NLB cluster contains an
application named App1 that is accessed by using the URL http://app1.contoso.com.
You plan to perform maintenance on Server1.
You need to ensure that all new connections to App1 are directed to Server2. The solution must not
disconnect the existing connections to Server1.
What should you run?
A. The Set-NlbCluster cmdlet
B. The Set-NlbClusterNode cmdlet
C. The Stop-NlbCluster cmdlet
D. The Stop-NlbClusterNode cmdlet
Correct Answer: D Explanation
Explanation/Reference:
The Stop-NlbClusterNode cmdlet stops a node in an NLB cluster. When you use the stop the nodes in the
cluster, client connections that are already in progress are interrupted. To avoid in- terrupting active
connections, consider using the -drain parameter, which allows the node to con- tinue servicing active
connections but disables all new traffic to that node.
-Drain <SwitchParameter>
Drains existing traffic before stopping the cluster node. If this parameter is omitted, existing traf- fic will be
dropped.
QUESTION 9
Your network contains two servers named HV1 and HV2. Both servers run Windows Server 2012 R2 and have the Hyper-V server role installed.
HV1 hosts 25 virtual machines. The virtual machine configuration files and the virtual hard disks are stored in D:\VM.
You shut down all of the virtual machines on HV1.
You copy D:\VM to D:\VM on HV2.
You need to start all of the virtual machines on HV2. You want to achieve this goal by using the minimum amount of administrative effort.
What should you do?
A. Run the Import-VMInitialReplication cmdlet.
B. From HV1, export all virtual machines to D:\VM. Copy D:\VM to D:\VM on HV2 and over- write the existing files. On HV2, run the Import Virtual Machine wizard.
C. From HV1, export all virtual machines to D:\VM. Copy D:\VM to D:\VM on HV2 and over- write the existing files. On HV2, run the New Virtual Machine wizard.
D. Run the Import-VM cmdlet.
Correct Answer: D Explanation
Explanation/Reference:
Explanation:
Import-VM
Imports a virtual machine from a file.
Example
Imports the virtual machine from its configuration file. The virtual machine is registered in- place, so its files
are not copied.

QUESTION 10
Your network contains an Active Directory domain named contoso.com. The domain contains two member servers named Server1 and Server2. All servers run Windows Server 2012 R2.
Server1 and Server2 have the Failover Clustering feature installed. The servers are configured as nodes in a failover cluster named Cluster1. Cluster1 contains a cluster disk resource.
A developer creates an application named App1. App1 is NOT a cluster-aware application. App1 runs as a service. App1 stores date on the cluster disk resource.
You need to ensure that App1 runs in Cluster1. The solution must minimize development effort.
Which cmdlet should you run?
A. Add-ClusterGenericServiceRole
B. Add-ClusterGenericApplicationRole
C. Add-ClusterScaleOutFileServerRole
D. Add-ClusterServerRole
Correct Answer: B Explanation
Explanation/Reference:
Add-ClusterGenericApplicationRole Configure high availability for an application that was not originally designed to run in a failover cluster. If you run an application as a Generic Application, the cluster software will start the application, then
periodically query the operating system to see whether the application appears to be run- ning. If so, it is
presumed to be online, and will not be restarted or failed over.
EXAMPLE 1 -Command Prompt: C:\PS>
Add-ClusterGenericApplicationRole -CommandLine NewApplication.exe
Name OwnerNode State
cluster1GenApp node2 Online Description
This command configures NewApplication.exe as a generic clustered application. A default name will be used for client access and this application requires no storage.

QUESTION 11
Your network contains an Active Directory domain named contoso.com. The domain contains a server named Server1 that runs Windows Server 2012 R2. The system properties of Server1 are shown in the exhibit. (Click the Exhibit button.)
You need to configure Server1 as an enterprise subordinate certification authority (CA). What should you do first?
A. Add RAM to the server.
B. Set the Startup Type of the Certificate Propagation service to Automatic.
C. Install the Certification Authority Web Enrollment role service.
D. Join Server1 to the contoso.com domain.
Correct Answer: D Explanation
Explanation/Reference:
Explanation: Enterprise CAs must be domain members. From the exhibit we see that it is only a
Workgroup member.
Note:
A new CA can be the root CA of a new PKI or subordinate to another in an existing PKI.
Enterprise subordinate certification authority
An enterprise subordinate CA must get a CA certificate from an enterprise root CA but can then issue
certificates to all users and computers in the enterprise. These types of CAs are often used for load
balancing of an enterprise root CA.
Enterprise CAs can be used to issue certificates to support such services as digital signatures, Se- cure
Multipurpose Internet Mail Extensions (S/MIME) secure mail, Secure Sockets Layer (SSL) or Transport
Layer Security (TLS) secured web access and smart card authentication. Enterprise CAsare used to
provide certificate services to internal users who have user accounts in the do- main.
Requiring Active Directory, an Enterprise subordinate CA obtains its certificate from an already existing
CA.
These types of CAs are used to provide smart-card-enabled logons by Windows XP and other Windows
Server 2003 machines.
After a root certification authority (CA) has been installed, many organizations will install one or more
subordinate CAs to implement policy restrictions on the public key infrastructure (PKI) and to issue
certificates to end clients. Using at least one subordinate CA can help protect the root CA from
unnecessary exposure. If a subordinate CA will be used to issue certificates to users or computers with
accounts in an Active Directory domain, installing the subordinate CA as an enterprise CA allows you to
use the client's existing account data in Active Directory Do- main Services (AD DS) to issue and manage
certificates and to publish certificates to AD DS. Membership in local Administrators, or equivalent, is the
minimum required to complete this procedure. If this will be an enterprise CA, membership in Domain
Admins, or equivalent, is the minimum required to complete this procedure.
