Q1. (Topic 6)
You have an Exchange Server 2013 organization that has two sites. The sites use a single namespace.
Each site contains two Exchange servers and a hardware load balancer. Mailboxes are distributed evenly between the sites.
Your company’s IT policy states that all users must be able to access their mailbox if one site fails.
You implement a DNS round robin solution for the Client Access server infrastructure.
When a site outage occurs, some users report experiencing intermittent slowness when they connect to their mailbox.
You need to recommend a solution to resolve the issue.
What are two possible recommendations to achieve this goal? Each correct answer presents a complete solution.
A. Remove the Virtual IP (VIP) of the failed data center.
B. Implement geo-dns
C. Add one additional Client Access server to each site.
D. Deploy a Windows Failover Cluster in each site.
E. Lower the TTL of the DNS records.
Answer: A,E
Q2. (Topic 6)
You have a database availability group (DAG). The DAG is configured as shown in the following table.
You need to prevent a split-brain condition if a restore operation of the DAG occurs.
What should you do?
A. Deploy an alternate witness server to each site.
B. Modify the Datacenter Activation Coordination (DAC) mode.
C. Set the quorum model of the cluster to Node and Disk Majority.
D. Deploy another Mailbox server to Site2.
Answer: B
Explanation:
Datacenter Activation Coordination (DAC) mode is a property setting for a database availability group (DAG). DAC mode is disabled by default and should be enabled for all DAGs with two or more members that use continuous replication.
If a catastrophic failure occurs that affects the DAG (for example, a complete failure of one of the datacenters), DAC mode is used to control the startup database mount behavior of a DAG. When DAC mode isn't enabled and a failure occurs that affects multiple servers in the DAG, and then when a majority of the DAG members are restored after the failure, the DAG will restart and attempt to mount databases. In a multi-datacenter configuration, this behavior could cause split brain syndrome, a condition that occurs when all networks fail, and DAG members can't receive heartbeat signals from each other. Split brain syndrome can also occur when network connectivity is severed between datacenters. Split brain syndrome is prevented by always requiring a majority of the DAG members (and in the case of DAGs with an even number of members, the DAG's witness server) to be available and interacting for the DAG to be operational. When a majority of the members are communicating, the DAG is said to have quorum.
Q3. (Topic 6)
Your company has offices in Tokyo, Bangkok, and Shanghai.
All connections to the Internet are routed through an Internet connection in the Tokyo office. All of the offices connect to each other by using a WAN link.
The network contains 10 servers that have Exchange Server 2010 installed. The servers are configured as shown in the following table.
You plan to deploy 10 servers that will have Exchange Server 2013 installed. The servers will be configured as shown in the following table.
Each site has an IP-PBX that provides telephony services for the mailboxes in that site by using unsecured SIP over TCP 5070. The IP-PBX uses the same port to connect to multiple SIP peers.
You need to recommend which tasks must be performed to ensure that the Unified Messaging (UM) features are available to the mailboxes if a single server fails.
Which three actions should you include in the recommendation? (Each correct answer presents part of the solution. Choose three.)
A. Configure the Exchange Server 2013 Mailbox servers to listen to unsecured SIP on TCP 5070.
B. Configure the Exchange Server 2013 Client Access servers to listen to unsecured SIP on TCP 5070.
C. Install the Client Access server role on the Exchange Server 2013 servers in the Shanghai and Bangkok offices.
D. Configure the Exchange Server 2013 Mailbox servers as additional SIP peers that contain new pilot identifiers.
E. Configure the Exchange Server 2013 Client Access servers as additional SIP peers that contain new pilot identifiers.
Answer: B,C,E
Explanation:
Note:
* Exchange 2013 Unified Messaging offers administrators: / A complete voice mail system Unified Messaging offers a complete voice mail solution using a single store, transport, and directory infrastructure. The store is provided by a Mailbox server and forwarding of incoming calls from a VoIP gateway or IP PBX is handled by a Client Access server. All email and voice mail messages can be managed from a single management point, using a single administration interface and tool set. / An Exchange security model The Microsoft Exchange Unified Messaging service on a Mailbox server and the Microsoft Exchange Unified Messaging Call Router service on a Client Access server run as a single Exchange server account. Consolidation
* The client access server (CAS) is a server role that handles all client connections to Exchange Server 2010 and Exchange 2013. The CAS supports all client connections to Exchange Server from Microsoft Outlook and Outlook Web App, as well as ActiveSync applications. The CAS also provides access to free/busy data in Exchange calendars.
The CAS is one of five server roles in Exchange Server 2007 and Exchange 2010, and one of two server roles in Exchange Server 2013. It must be installed in every Exchange Server organization and on every Active Directory (AD) site that has the Exchange mailbox server role installed.

Q5. (Topic 2)
You need to recommend a solution to ensure that during the planned migrations, all Autodiscover requests are processed by the Exchange Server 2013 Client Access servers.
What should you recommend?
A. On the Exchange Server 2007 Client Access servers, modify the AutodiscoverServiceInternalURI.
B. On the Exchange Server 2007 Client Access servers, modify the ExternalURL value of the Autodiscover virtual directory.
C. On the Exchange Server 2013 Client Access servers, modify the ExternalURL value of the Autodiscover virtual directory.
D. On the Exchange Server 2013 Client Access servers, modify the AutodiscoverServiceInternalURI.
Answer: A
Explanation:
The Exchange Server 2007 Client Access servers must be configured to use the Exchange Server 2013 Client Access server. We do this by setting the AutodiscoverServiceInternalURI property.
Q6. DRAG DROP - (Topic 6)
You have an Exchange Server 2013 database availability group (DAG). Each member of the DAG has two network interfaces named Network1 and Network2. Network1 is used for client connections. Network2 is used for database replication.
Network2 fails.
You discover that replication traffic is sent over Network1.
You need to ensure that all of the database replication traffic is sent over Network2. The solution must minimize database replication downtime.
Which three actions should you perform?
To answer, move the three appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Q7. (Topic 6)
You have an Exchange Server 2013 organization that contains a database available group (DAG) named DAG1. DAG1 contains three Mailbox servers named Server1, Server2, and Server3. DAG1 contains a mailbox database copy named DB1.
You implement a lagged copy of DB1 on Server3. The copy lag time is seven days.
You need to ensure that copies of successfully processed email messages are stored on Server1 and Server2 for seven days.
What should you modify?
A. The Shadow Redundancy settings
B. The Safety Net settings
C. The settings of DAG1
D. The settings of DB1
Answer: B
Explanation:
Microsoft Exchange 2013 Safety Net is a new feature in Exchange Server 2013 that prevents data loss by maintaining a queue of successfully delivered messages.
The Exchange 2013 Safety Net is essentially a delivery queue that exists on each Exchange 2013 mailbox server. Each time a message is delivered to a database, a copy of that message is held within the Safety Net. The message copy remains in the Safety Net until its expiration date, which is determined by the administrator.
