Topic 3, Mix Questions

NEW QUESTION 2
You have an Azure subscription that contains two resource groups named RG1 and RG2. RG2 does not contain any resources. RG1 contains the resources in the following table.

Which resource can you move to RG2?

• A. W10_OsDisk
• B. VNet1
• C. VNet3
• D. W10

Answer: B

Explanation: When moving a virtual network, you must also move its dependent resources. For example, you must move gateways with the virtual network. VM W10, which is in Vnet1, is not a dependent resource.

NEW QUESTION 3
You need to identify the storage requirements for Contoso.
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
Contoso is moving the existing product blueprint files to Azure Blob storage.
Use unmanaged standard storage for the hard disks of the virtual machines. We use Page Blobs for these. Box 2: No
Box 3: No

NEW QUESTION 4
You plan to back up an Azure virtual machine named VM1.
You discover that the Backup Pre-Check status displays a status of Warning. What is a possible cause of the Warning status?

• A. VM1 does not have the latest version of WaAppAgent.exe installed.
• B. VM1 has an unmanaged disk.
• C. VM1 is stopped.
• D. A Recovery Services vault is unavailable.

Answer: A

Explanation: The Warning state indicates one or more issues in VM’s configuration that might lead to backup failures and provides recommended steps to ensure successful backups. Not having the latest VM Agent installed, for example, can cause backups to fail intermittently and falls in this class of issues.

Your company registers a domain name of contoso.com.
You create an Azure DNS zone named contoso.com, and then you add an A record to the zone for a host named www that has an IP address of 131.107.1.10.
You discover that Internet hosts are unable to resolve www.contoso.com to the 131.107.1.10 IP address.
You need to resolve the name resolution issue.
Solution: You create a PTR record for www in the contoso.com zone. Does this meet the goal?

• A. Yes

NEW QUESTION 11
Your company registers a domain name of contoso.com.
You create an Azure DNS named contoso.com and then you add an A record to the zone for a host named www that has an IP address of 131.107.1.10.
You discover that Internet hosts are unable to resolve www.contoso.com to the 131.107.1.10 IP address. You need to resolve the name resolution issue.

NEW QUESTION 14
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.

Overview
The following section of the exam is a lab. In this section, you will perform a set of tasks in a live environment. While most functionality will be available to you as it would be in a live environment, some functionality (e.g., copy and paste, ability to navigate to external websites) will not be possible by design. Scoring is based on the outcome of performing the tasks stated in the lab. In other words, it doesn’t matter how you accomplish the task, if you successfully perform it, you will earn credit for that task.
Labs are not timed separately, and this exam may have more than one lab that you must complete. You can use as much time as you would like to complete each lab. But, you should manage your time appropriately to ensure that you are able to complete the lab(s) and all other sections of the exam in the time provided.

You plan to create 100 Azure virtual machines on each of the following three virtual networks:
VNET1005a
VNET1005b
VNET1005c
All the network traffic between the three virtual networks will be routed through VNET1005a.
You need to create the virtual networks, and then to ensure that all the Azure virtual machines can connect to other virtual machines by using their private IP address. The solution must NOT require any virtual network gateways and must minimize costs.
What should you do from the Azure portal before you configure IP routing?

Answer:

Explanation: Step 1: Click Create a resource in the portal.
Step 2: Enter Virtual network in the Search the Marketplace box at the top of the New pane that appears. Click Virtual network when it appears in the search results.
Step 3: Select Classic in the Select a deployment model box in the Virtual Network pane that appears, then click Create.
Step 4: Enter the following values on the Create virtual network (classic) pane and then click Create: Name: VNET1005a
Address space: 10.0.0.0/16 Subnet name: subnet0 Resource group: Create new
Subnet address range: 10.0.0.0/24
Subscription and location: Select your subscription and location.
Step 5: Repeat steps 3-5 for VNET1005b (10.1.0.0/16, 10.1.0.0/24), and for VNET1005c 10.2.0.0/16, 10.2.0.0/24).

NEW QUESTION 19
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.
