Which four actions should you recommend in sequence? (To answer, move the a the list of actions to the answer area and arrange them in the correct order.)
Box 1: Run Export-CsRgsConfiguration
Box 2: Restore the Central Management store to a server in the New York Office.
Box 3: Run Import-CsRgsConfiguration.
Box 4: Instruct all of the members of RG1 who are configured as formal agents to sign in again.
/ You have a response group named RG1.
/ RG1 must be used by the users in the New York office if the network in the Denver office is
unavailable for an extended period of time.
/ Contoso plans to implement the following changes to the network:
Establish new branch offices in New York and Montreal that connect to the Denver office by using
a WAN link
*(box 1, box 3) Export-CsRgsConfiguration
Exports data from an existing Response Group application configuration. This data, saved as a .ZIP file, can later be imported using the Import-CsRgsConfiguration cmdlet.
*(box 4) Formal agents are considered active when they manually sign in to the Response Group application web sign in page. Informal agents are considered active when they login to the Lync client, because they are automatically signed in to their Response Groups when they login. An agent who does not sign in or out of the group is called an informal agent. Informal agents are automatically signed in to the group when they sign in to Lync Server, and they cannot sign out of the group.

Topic 6, Mix Questions
You have an Active Directory domain named contoso.com.
Your company has a Microsoft Office 365 subscription. Twenty users are enabled for Microsoft Lync Online. The users frequently travel.
The users report that they receive the following error message when they attempt to sign in to Microsoft Lync from the office: "Cannot sign in because the server is temporarily unavailable. If the problem continues, please contact your support team."
You verify that the users can sign in to Lync when they connect from the Internet. You need to ensure that all of the users can sign in to Lync.
Which alias (CNAME) record should you create in the internal DNS domain?
To answer, select the appropriate record name and the appropriate record target in the answer area.
*The FQDN must be the primary on the cert or be a SAN entry for the cert. Usually, the FQDN would be sip.mydomain.com. Create a SRV record for sip to point to the real FQDN of the host.
*The Lync 2013 Preview client can be set to use manual configuration to check whether the sign-in issue is related to DNS resolution issues. If manual configuration works and automatic configuration doesn't work, it usually indicates a problem with DNS resolution. This usually occurs because the DNS SRV records aren't present or are inaccessible from the client computer. To set Lync 2013 Preview to use manual configuration, follow these steps:
In the upper-right area of Lync 2013 Preview, click the Gear icon to open the Options page.
In the Lync - Options dialog box, click Personal.
Next to the sign-in address, click Advanced.
Make sure that Manual Configuration is selected and that the configuration values are exactly as follows:
Internal server name or IP address: sipdir.online.lync.com:443
External server name or IP address: sipdir.online.lync.com:443
