Dynamics CRM Online Deployment Exam MB2-706

Today I took and passed the Dynamics CRM Online Deployment exam MB2-706. The title only mention Dynamics CRM Online, however when I look more carefully on the skills measured section, there are some topics that quite overlapped with the Dynamics CRM Installation exam MB2-708.

First of all, I won’t break the NDA of the exam but I would like to give my thought on the exam. And if you ask me anything about sample questions and answers, I would say upfront, but sorry I won’t give anything.

As I mentioned earlier on the post that there are some overlapped topics with the installation exam, however I was quite unprepared when I was given some questions that supposedly only applicable for on-premise installation. Then I spent the time of the feedback to point out the questions that not accurate for the Online Deployment. Apart from that, the rest of the exams questions completely reflects the items that listed on the skills measured.

For the preparation of the exam, I just used the Dynamics CRM Online Deployment MOC training material from PartnerSource, however the training itself is not sufficient to pass the exam. Referring back to the skills measured, there are some topics that were not covered in the Online Deployment training, maybe combined with the installation course would be beneficial. Reading the Implementation and Administration guide also a good supplement to prepare the exam.

And one more tip for the exam: Second Shot. Microsoft is offering the second chance if you don’t pass the exam for the first time. The Second Shot offer valid for MCP exams that is taken between January 5, 2015, and May 31, 2015. My tip on this Second Shot is not use this opportunity to memorise the questions, but to identify on which section(s) that we are weak at, then do better preparation for the second chance.

I hope this helps!

I have just completed and passed the MB2-706 certification. (Online deployment certification.)

Interesting as the first certification I have completed online, not sure I’ll rush towards taking the exam on-line again.

I can’t / won’t break the NDA by mentioning specific questions but if you are preparing for the exam, the first tip I have it to actually prepare for the MB2-708 and MB2-706 exams together. There is a large amount of cross over. (MB2-708 being the CRM installations exam.)

I expected the main focus of MB2-706 to be Office 365 admin of CRM subscriptions and instances. Don’t get me wrong that stuff is covered but the exam goes quite a bit wider than that. Review the skills measured on the Microsoft site and ensure you have EVERYTHING covered.

I was unprepared for the number of questions about Outlook deployment and Email Router set-up. So much so that I did the unthinkable and failed first time out! Just shows that the old saying of “fail to prepare, prepare to fail” is bang on.

The “positive” was I got to try out using second shot! Your second attempt is currently still free with second shot. Originally this involved a lengthy process of obtaining a voucher and entering the code when you book the exam. They have made the process smoother these days, if you are eligible for second shot its automatically allocated when you book the exam.

Several questions came up about the process of upgrading from CRM2013 to CRM2015. When you are conducting research for the exam don’t just focus on a vanilla install. Look at any specific considerations for folks moving from earlier versions of CRM.

Be prepared for frustration with some questions! All the questions are valid in the wider context of a CRM deployment but quite a few seemed irrelevant for an online deployment exam. But to be fair Microsoft do make this clear in the skills measured. The word server appears six times in the administration section of the skills measured, that should have been my clue that some questions might feel more aligned to an on premise deployment exam. This area of the skills measured does not have a focus on online deployment and as this is up to 25% of the questions you should expect a significant number of questions that might feel off topic.

QUESTION 1
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

Answer: B
Explanation:
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 running. 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 2
Your network contains an Active Directory domain named contoso.com. The domain contains a file server named Server1 that runs Windows Server 2012 R2. All client computers run Windows 8.
You need to configure a custom Access Denied message that will be displayed to users when they are denied access to folders or files on Server1.
What should you configure?

A. A classification property
B. The File Server Resource Manager Options
C. A file management task
D. A file screen template

Answer: B
Explanation:
Access-denied assistance can be configured by using the File Server Resource Manager console on the file server.
Note: Access-denied assistance is a new feature in Windows Server 2012, which provides the following ways to troubleshoot issues that are related to access to files and folders:
* Self-assistance. If a user can determine the issue and remediate the problem so that they can get the requested access, the impact to the business is low, and no special exceptions are needed in the central access policy. Access-denied assistance provides an access-denied message that file server administrators can customize with information specific to their organizations. For example, an administrator could set the message so that users can request access from a data owner without involving the file server administrator.
Reference: Scenario: Access-Denied Assistance


QUESTION 2
Your network contains an Active Directory domain named contoso.com. The domain contains a member server named Server1 that has the Active Directory Federation Services server role installed. All servers run Windows Server 2012.
You complete the Active Directory Federation Services Configuration Wizard on Server1.
You need to ensure that client devices on the internal network can use Workplace Join.
Which two actions should you perform on Server1? (Each correct Answer presents part of the solution. Choose two.)

A. Run Enable-AdfsDeviceRegistration -PrepareActiveDirectory.
B. Edit the multi-factor authentication global authentication policy settings.
C. Run Enable-AdfsDeviceRegistration.
D. Run Set-AdfsProxyProperties HttpPort 80.
E. Edit the primary authentication global authentication policy settings.

Answer: C,E
Explanation:
C. To enable Device Registration Service
On your federation server, open a Windows PowerShell command window and type: Enable-AdfsDeviceRegistration
Repeat this step on each federation farm node in your AD FS farm.
E. Enable seamless second factor authentication
Seamless second factor authentication is an enhancement in AD FS that provides an added level of access protection to corporate resources and applications from external devices that are trying to access them. When a personal device is Workplace Joined, it becomes a ‘known’ device and administrators can use this information to drive conditional access and gate access to resources.
To enable seamless second factor authentication, persistent single sign-on (SSO) and conditional access for Workplace Joined devices.
In the AD FS Management console, navigate to Authentication Policies. Select Edit Global Primary Authentication. Select the check box next to Enable Device Authentication, and then click OK.
Reference: Configure a federation server with Device Registration Service.

QUESTION 3
You create a new virtual disk in a storage pool by using the New Virtual Disk Wizard. You discover that the new virtual disk has a write-back cache of 1 GB.
You need to ensure that the virtual disk has a write-back cache of 5 GB.
What should you do?

A. Detach the virtual disk, and then run the Resize-VirtualDisk cmdlet.
B. Detach the virtual disk, and then run the Set-VirtualDisk cmdlet.
C. Delete the virtual disk, and then run the New-StorageSubSystemVirtualDisk cmdlet.
D. Delete the virtual disk, and then run the New-VirtualDisk cmdlet.

Answer: D
Explanation:
So what about changing the cache size? Well, you can't modify the cache size, but you can specify it at the time that you create a new virtual hard disk. In order to do so, you have to use Windows PowerShell.
New-VirtualDisk –StoragePoolFriendlyName "<storage pool name>" –FriendlyName "<v
Reference: Using Windows Server 2012's SSD Write-Back Cache


QUESTION 4
Your company has offices in Montreal, New York, and Amsterdam.
The network contains an Active Directory forest named contoso.com. An Active Directory site exists for each office. All of the sites connect to each other by using the DEFAULTIPSITELINK site link.
You need to ensure that only between 20:00 and 08:00, the domain controllers in the Montreal office replicate the Active Directory changes to the domain controllers in the Amsterdam office.
The solution must ensure that the domain controllers in the Montreal and the New York offices can replicate the Active Directory changes any time of day.
What should you do?

A. Create a new site link that contains Montreal and Amsterdam. Remove Amsterdam from DEFAULTIPSITE1INK. Modify the schedule of DEFAULTIPSITELINK.
B. Create a new site link that contains Montreal and Amsterdam. Create a new site link bridge. Modify the schedule of DEFAULTIPSITELINK.
C. Create a new site link that contains Montreal and Amsterdam. Remove Amsterdam from DEFAULTIPSITELINK. Modify the schedule of the new site link.
D. Create a new site link that contains Montreal and Amsterdam. Create a new site link bridge. Modify the schedule of the new site link.

Answer: C
Explanation:
We create a new site link between Montreal and Amsterdam and schedule it only between 20:00 and 08:00. To ensure that traffic between Montreal and Amsterdam only occurs at this time we also remove Amsterdam from the DEFAULTIPSITELINK.

QUESTION 5
Your network contains an Active Directory domain named contoso.com. The domain contains a server named Server1 that runs Windows Server 2012 R2 and has the DHCP Server server role installed.
You need to create an IPv6 scope on Server1. The scope must use an address space that is reserved for private networks. The addresses must be routable.
Which IPV6 scope prefix should you use?

A. 2001:123:4567:890A::
B. FE80:123:4567::
C. FF00:123:4567:890A::
D. FD00:123:4567::

Answer: D
Explanation:
Explanation/Reference:
* A unique local address (ULA) is an IPv6 address in the block fc00::/7, defined in RFC 4193. It is the approximate IPv6 counterpart of the IPv4 private address.
The address block fc00::/7 is divided into two /8 groups: / The block fc00::/8 has not been defined yet.
/ The block fd00::/8 is defined for /48 prefixes, formed by setting the 40 least-significant bits of the prefix to a randomly generated bit string.
* Prefixes in the fd00::/8 range have similar properties as those of the IPv4 private address ranges:
/ They are not allocated by an address registry and may be used in networks by anyone without outside involvement.
/ They are not guaranteed to be globally unique.
/ Reverse Domain Name System (DNS) entries (under ip6.arpa) for fd00::/8 ULAs cannot be delegated in the global DNS.
Reference: RFC 4193


QUESTION 6
Your network contains an Active Directory forest named contoso.com.
Users frequently access the website of an external partner company. The URL of the website is http://partners.adatum.com.
The partner company informs you that it will perform maintenance on its Web server and that the IP addresses of the Web server will change.
After the change is complete, the users on your internal network report that they fail to access the website. However, some users who work from home report that they can access the website.
You need to ensure that your DNS servers can resolve partners.adatum.com to the correct IP address immediately.
What should you do?

A. Run dnscmd and specify the CacheLockingPercent parameter.
B. Run Set-DnsServerGlobalQueryBlockList.
C. Run ipconfig and specify the Renew parameter.
D. Run Set-DnsServerCache.

Answer: D
Explanation:
The Set-DnsServerCache cmdlet modifies cache settings for a Domain Name System (DNS) server.
Run Set-DnsServerCache with the -LockingPercent switch.
/ -LockingPercent<UInt32>
Specifies a percentage of the original Time to Live (TTL) value that caching can consume. Cache locking is configured as a percent value. For example, if the cache locking value is set to 50, the DNS server does not overwrite a cached entry for half of the duration of the TTL. By default, the cache locking percent value is 100. This value means that the DNS server will not overwrite cached entries for the entire duration of the TTL.
Note. A better way would be clear the DNS cache on the DNS server with either Dnscmd /ClearCache (from command prompt), or Clear-DnsServerCache (from Windows PowerShell).
Reference: Set-DnsServerCache
http://technet.microsoft.com/en-us/library/jj649852.aspx
Incorrect:
Not A. You need to use the /config parameter as well:
You can change this value if you like by using the dnscmd command:
dnscmd /Config /CacheLockingPercent<percent>
