Objective 1.3: Review

  1. Correct Answers: A and C

    1. Correct: You need to ensure that a trust relationship is established between the resource forest and the domains that host accounts in the account forests. The easiest way to accomplish this is to set up forest trusts, although in environments with more complex security needs you may configure more selective trusts.

    2. Incorrect: You do not need to install Exchange 2010 in the account forests to accomplish this goal. Exchange 2010 is installed in multiple forests.

    3. Correct: Linked mailboxes are created in the resource forest and linked to accounts in the account forests.

    4. Incorrect: You create linked mailboxes in the resource forest and not in the account forest.

  2. Correct Answer: D

    1. Incorrect: The New-Mailbox cmdlet is used to create mailboxes. In this case, you want to create a group which uses a query against an Active Directory attribute to populate its membership.

    2. Incorrect: The New-DistributionGroup cmdlet allows you to create a new distribution group. Distribution groups have static memberships and require manual membership changes, which is not appropriate given management’s requirements in this situation.

    3. Incorrect: The Set-DistributionGroup cmdlet is used to modify the properties of an existing distribution group. You cannot use the Set-DistributionGroup cmdlet to create a dynamic distribution group.

    4. Correct: Dynamic distribution groups can be configured using queries based on an Active Directory attribute, such as department membership. The membership of dynamic distribution groups is determined when the group is expanded on a Hub Transport server.

  3. Correct Answer: C

    1. Incorrect: You cannot use the New-MailboxDatabase cmdlet to modify the default mailbox database maximum size limit on an Exchange Server 2010 SP1 mailbox server. You can only modify this limit by editing the registry.

    2. Incorrect: Each Exchange mailbox server can only host one public folder database. Because there are only five mailbox servers, there is a maximum of five public folder databases.

    3. Incorrect: Each Exchange mailbox server can only host one public folder database. Because there are only five mailbox servers, there is a maximum of five public folder databases.

    4. Incorrect: Each Exchange mailbox server can only host one public folder database. Because there are only five mailbox servers, there is a maximum of five public folder databases.

  5. Correct Answers: A, C, and D

    1. Correct: You use the New-AcceptedDomain cmdlet to create a new accepted domain. This will be necessary if you want to use the email domain cohowinery.com in an email address policy.

    2. Incorrect: Get-EmailAddressPolicy lists the properties of an email address policy. You can’t use this cmdlet to create and apply a new email address policy.

    3. Correct: You use the New-EmailAddressPolicy to create a policy that will apply the cohowinery.com email domain in default reply-to addresses in the organization. It is also possible to modify the existing policy, but that option was not available.

    4. Correct: You use the Update-EmailAddressPolicy cmdlet to apply a new or modified email address policy.

Objective 1.3: Thought Experiment

  1. You should set up linked mailboxes in the Contoso.com Exchange organization for users with accounts in the Fabrikam.com forest.

  2. You can modify the existing email address policy or create a new email address policy.

  3. You should create a static distribution group. This will allow you to delegate the appropriate administrative privileges to Simone from Accounts Receivable.

  4. You should make Simone from Accounts Receivable the group owner, also known as the group manager.

  5. Set the approval setting to Owner Approval. This will allow Simone from Accounts Receivable to approve membership.

Objective 1.4: Review

  1. Correct Answer: A

    1. Correct: The LoadGen tool, also known as the Exchange Server Load Generator, allows you to test the adequacy of a CAS deployment for a specific number of clients.

    2. Incorrect: The Jetstress tool allows you to simulate mailbox database I/O and is suitable for testing mailbox server performance, but it does not allow you to simulate specific client load against a CAS deployment.

    3. Incorrect: The Exchange Best Practices Analyzer allows you to compare an Exchange deployment against best practices, but it does not allow you to simulate specific client load against a CAS deployment.

    4. Incorrect: The Remote Connectivity Analyzer allows you to verify that ActiveSync, Exchange Web Services, Outlook, and Internet Email work correctly, but it cannot be used to simulate specific client load against a CAS deployment.

  2. Correct Answer: C

    1. Incorrect: It is necessary to have a Client Access Server in each site where there is a mailbox server. Deploying one Client Access Server would be insufficient when the proposed design has five sites with mailbox servers.

    2. Incorrect: It is necessary to have a Client Access Server in each site where there is a mailbox server. Deploying four Client Access Server would be insufficient when the proposed design has five sites with mailbox servers.

    3. Correct: It is necessary to have a Client Access Server in each site where there is a mailbox server. Because there are five sites, a minimum of five Client Access Servers are necessary.

    4. Incorrect: It is necessary to have a Client Access Server in each site where there is a mailbox server. Although having seven Client Access Servers would provide redundancy in the event that a Client Access Server failed, five Client Access Servers is the minimum amount necessary.

  3. Correct Answer: A

    1. Correct: The mailbox servers are only in a single site, so you only need to deploy a single Client Access Server to support this configuration.

    2. Incorrect: You only need to deploy a single Client Access Server to support this configuration.

    3. Incorrect: You only need to deploy a single Client Access Server to support this configuration.

    4. Incorrect: You only need to deploy a single Client Access Server to support this configuration.

  4. Correct Answer: A

    2. Incorrect: Microsoft’s theoretical optimum ratio is that there are three processor cores on a site’s Client Access Servers for every four processor cores on a site’s Mailbox servers.

    3. Incorrect: Microsoft’s theoretical optimum ratio is that there are three processor cores on a site’s Client Access Servers for every four processor cores on a site’s Mailbox servers.

    4. Incorrect: Microsoft’s theoretical optimum ratio is that there are three processor cores on a site’s Client Access Servers for every four processor cores on a site’s Mailbox servers.

  5. Correct Answer: C

    1. Incorrect: Configuring the Autodiscover service for Internet Access allows clients on external networks to be configured automatically through Autodiscover. Taking this step will not ensure that Outlook 2010 clients get Autodiscover information from the closest Active Directory site.

    2. Incorrect: Configuring the Autodiscover for multiple forests allows users running Outlook 2007 or Outlook 2010 in one forest to access Client Access Servers in a remote forest. Taking this step will not ensure that Outlook 2010 clients get Autodiscover information from the closest Active Directory site.

    3. Correct: Configuring the Autodiscover service for Site Affinity ensures that Outlook 2007 and Outlook 2010 clients get Autodiscover information from the closest Active Directory site.

    4. Incorrect: Configuring the Exchange ActiveSync Autodiscover settings allows automatic configuration of ActiveSync clients. Taking this step will not ensure that Outlook 2010 clients get Autodiscover information from the closest Active Directory site.

Objective 1.4: Thought Experiment

  1. You must deploy Client Access Serves in the Auckland, Wellington, Dunedin, and Christchurch sites.

  2. You can ensure that clients using Autodiscover are provisioned with profile information from the closest Active Directory site by configuring site affinity.

  3. You can configure CAS to use the same name for all services, you can use certificates that support SANs, or you could configure the CAS with wildcard certificates.

  4. You should deploy Outlook Anywhere because you want to allow remote access to Exchange mailboxes for clients running Outlook 2010 without configuring VPN or DirectAccess.

  5. Because you need to support users accessing Outlook Web App from personal computers, you should use a trusted third-party CA, which will minimize the problems involved in getting clients to trust the certificates.

Objective 1.5: Review

  1. Correct Answer: A

    1. Correct: The Exchange Server Load Generator 2010 allows you to test a simulated client workload against all aspects of an Exchange Server 2010 deployment. You can use this tool to determine how many clients a simulated Exchange Server 2010 deployment can comfortably handle.

    2. Incorrect: The Exchange Server Jetstress 2010 tool allows you to benchmark mailbox server storage, but does not allow you to test other aspects of an Exchange Server deployment.

    3. Incorrect: The Exchange Server Remote Connectivity Analyzer allows you to test client connectivity configuration, but does not allow you to test an Exchange server deployment against a simulated number of clients.
