NEW QUESTION 11
You configure Azure AD Connect for Azure Active Directory Seamless Single Sign-On (Azure AD Seamless SSO) for an on-premises network. Users report that when they attempt to access myapps.microsoft.com, they are prompted multiple times to sign in and are forced to use an account name that ends with onmicrosoft.com.
You discover that there is a UPN mismatch between Azure AD and the on-premises Active Directory. You need to ensure that the users can use single-sign on (SSO) to access Azure resources.
What should you do first?

• A. From the on-premises network, deploy Active Directory Federation Services (AD FS).
• B. From Azure AD, add and verify a custom domain name.
• C. From the on-premises network, request a new certificate that contains the Active Directory domain name.
• D. From the server that runs Azure AD Connect, modify the filtering options.

Answer: B

Explanation: Azure AD Connect lists the UPN suffixes that are defined for the domains and tries to match them with a custom domain in Azure AD. Then it helps you with the appropriate action that needs to be taken. The Azure AD sign-in page lists the UPN suffixes that are defined for on-premises Active Directory and displays the corresponding status against each suffix. The status values can be one of the following:
State: Verified
Azure AD Connect found a matching verified domain in Azure AD. All users for this domain can sign in by using their on-premises credentials.
State: Not verified
Azure AD Connect found a matching custom domain in Azure AD, but it isn't verified. The UPN suffix of the users of this domain will be changed to the default .onmicrosoft.com suffix after synchronization if the domain isn't verified.
Action Required: Verify the custom domain in Azure AD.

NEW QUESTION 13
You need to resolve the Active Directory issue. What should you do?

• A. From Active Directory Users and Computers, select the user accounts, and then modify the User PrincipalName value.
• B. Run idfix.exe, and then use the Edit action.
• C. From Active Directory Domains and Trusts, modify the list of UPN suffixes.
• D. From Azure AD Connect, modify the outbound synchronization rule.

Answer: B

Explanation: IdFix is used to perform discovery and remediation of identity objects and their attributes in an on-premises Active Directory environment in preparation for migration to Azure Active Directory. IdFix is intended for the Active Directory administrators responsible for directory synchronization with Azure Active Directory.
Scenario: Active Directory Issue
Several users in humongousinsurance.com have UPNs that contain special characters. You suspect that some of the characters are unsupported in Azure AD.

NEW QUESTION 14
You have an Azure subscription that contains the resources in the following table.

VM1 and VM2 are deployed from the same template and host line-of-business applications accessed by using Remote Desktop. You configure the network security group (NSG) shown in the exhibit. (Click the Exhibit button.)

You need to prevent users of VM1 and VM2 from accessing websites on the Internet.
What should you do?

• A. Associate the NSG to Subnet1.

• C. Change the DenyWebSites outbound security rule.
• D. Change the Port_80 inbound security rule.

Answer: A

Explanation: You can associate or dissociate a network security group from a network interface or subnet.
The NSG has the appropriate rule to block users from accessing the Internet. We just need to associate it with Subnet1.
References: https://docs.microsoft.com/en-us/azure/virtual-network/manage-network-security-group

NEW QUESTION 15
You have an Azure subscription named Subscription1. Subscription1 contains the virtual machines in the following table.

Subscription1 contains a virtual network named VNet1 that has the subnets in the following table.

VM3 has a network adapter named NIC3. IP forwarding is enabled on NIC3. Routing is enabled on VM3. You create a route table named RT1. RT1 is associated to Subnet1 and Subnet2 and contains the routes in the following table.

You apply RT1 to Subnet1.
For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Answer:

Explanation: Box 1: Yes
Traffic from VM1 and VM2 can reach VM3 thanks to the routing table, and as IP forwarding is enabled on VM3, traffic from VM3 can reach VM1.
Box 2: No
VM3, which has IP forwarding, must be turned on, in order for traffic from VM2 to reach VM1. Box 3: Yes
The traffic from VM1 will reach VM3, which thanks to IP forwarding, will send the traffic to VM2. References: https://www.quora.com/What-is-IP-forwarding

NEW QUESTION 17
You have a virtual network named VNet1 as shown in the exhibit. (Click the Exhibit tab.)

No devices are connected to VNet1.
You plan to peer VNet1 to another virtual network named VNet2 in the same region. VNet2 has an address space of 10.2.0.0/16.
You need to create the peering. What should you do first?

• A. Configure a service endpoint on VNet2.
• B. Modify the address space of VNet1.
• C. Add a gateway subnet to VNet1.
• D. Create a subnet on VNet1 and VNet2.

Answer: B

Explanation: The virtual networks you peer must have non-overlapping IP address spaces. The exhibit indicates that VNet1 has an address space of 10.2.0.0/16, which is the same as VNet2, and thus overlaps. We need to change the address space for VNet1.

NEW QUESTION 18
You have an Azure subscription.
You plan to use Azure Resource Manager templates to deploy 50 Azure virtual machines that will be part of the same availability set.
You need to ensure that as many virtual machines as possible are available if the fabric fails or during servicing.
How should you configure the template? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Select two alternatives below.

• A. platformFaultDomainCount: 0
• B. platformFaultDomainCount: 1
• C. platformFaultDomainCount: 2
• D. platformFaultDomainCount: 3
• E. platformFaultDomainCount: 4
• F. platformUpdateDomainCount: 10
• G. platformUpdateDomainCount: 20
• H. platformUpdateDomainCount: 25
• I. platformUpdateDomainCount: 30
• J. platformUpdateDomainCount: 40
• K. platformUpdateDomainCount: 50

Answer: CG

Explanation: Use two fault domains.
2 or 3 is max, depending on which region you are in. Use 20 for platformUpdateDomainCount
Increasing the update domain (platformUpdateDomainCount) helps with capacity and availability planning when the platform reboots nodes. A higher number for the pool (20 is max) means that fewer of their nodes in any given availability set would be rebooted at once.
