You plan to configure a federation trust between Fabrikam and Contoso.
You need to recommend a certificate for the federation trust.
Which of the following certificates is the best recommendation? (More than one answer choice may achieve the goal. Select the BEST answer.)

A.    a certificate from a third-party certification authority (CA)
B.    the self-signed certificate automatically generated by the Exchange 2010 Setup wizard
C.    the self-signed certificate automatically generated by the New Federation Trust wizard
D.    a certificate from an internal certification authority (CA)

Answer: C

QUESTION 163
You are the enterprise administrator for an Exchange Server 2010 organization.
All users run Microsoft Office Outlook 2010.
You are designing a sharing solution for your organization and a partner organization.
The partner organization also uses Exchange Server 2010.
You need to recommend a strategy for sharing information with the partner organization to meet the following requirements:

– Provide cross-organizational access to user contacts
– Provide cross-organizational access to free\busy information

A.    Implementing Microsoft Identify Lifecycle Manager (ILM) 2007
B.    Implementing Federated Delegation
C.    Running the Microsoft Exchange Inter-Organization Replication tool
D.    Creating cross-forest trusts

Answer: B
Explanation:
Information workers frequently need to collaborate with external recipients, vendors, partners, and customers and share their free/busy (also known as calendar availability) and contact information. Federation in Microsoft Exchange Server 2010 helps with these collaboration efforts. Federation refers to the underlying trust infrastructure that supports federated delegation, an easy method for users to share calendar and contact information with recipients in other external federated organizations. To learn more about federated delegation, see Understanding Federated Delegation.

wps3553.tmp

Example
Two Exchange organizations, Contoso, Ltd. and Fabrikam, Inc., want their users to be able to share free/busy information with each other. Each organization creates a federation trust with the Microsoft Federation Gateway and configures its account namespace to include the domain used for its user’s e-mail address domain. Contoso employees use one of the following e-mail address domains:
contoso.com, contoso.co.uk, or contoso.ca. Fabrikam employees use one of the following e-mail address domains: fabrikam.com, fabrikam.org, or fabrikam.net. Both organizations make sure that all accepted e-mail domains are included in the account namespace for their federation trust with the Microsoft Federation Gateway. Rather than requiring a complex Active Directory forest or domain trust configuration between the two organizations, both organizations configure an organization relationship with each other to enable free/busy sharing.
The following figure illustrates the federation configuration between Contoso, Ltd. and Fabrikam, Inc.

QUESTION 164
Contoso, Ltd. has an Exchange Server 2010 environment that accepts email for the contoso.com email domain. Fabrikam, Inc. has an Exchange Server 2010 environment that accepts mail for the fabrikam.com email domain.
Contoso acquires Fabrikam and establishes an internal network connection between the two companies.
After the acquisition, only the Contoso Exchange Server environment accepts external email.
You have the following requirements:

– Retain existing fabrikam.com email addresses.
– Enable users in both Exchange Server environments to receive mail at contoso.com email addresses.

You need to recommend a solution that meets the requirements.
Which two actions should you recommend? (Each correct answer presents part of the solution.
Choose two.)

A.    Create an internal relay accepted domain for contoso.com.
B.    Create an external relay accepted domain for contoso.com.
C.    Create an internal receive connector.
D.    Create an internal send connector.

Answer: AD
Explanation:
You need to create an internal relay accepted domain and a send connector to relay to the fabrikam servers

Internal Relay Domain
When you configure an internal relay domain, some or all of the recipients in this domain don’t have mailboxes in this Exchange organization. Mail from the Internet is relayed for this domain through Hub Transport servers in this Exchange organization. This configuration is used in the scenarios that are described in this section.

In the following figure, Fourthcoffee.com is configured as an internal relay domain for the Exchange 2010 organization in the Contoso.com forest. The MX resource records for Fourthcoffee.com reference a public IP address for the Contoso.com organization. A forest trust exists between Fourthcoffee.com and Contoso.com, and GAL synchronization is configured. The Contoso.com Edge Transport server accepts messages for the Fourthcoffee.com SMTP domain from the Internet and then relays those messages to the Hub Transport servers in the Contoso.com Exchange organization. The messages are then routed to the Hub Transport servers in the Fourthcoffee.com Exchange organization. A cross-forest Send connector is configured for routing messages from Contoso.com to Fourthcoffee.com. Messages that are sent from Fourthcoffee.com to external recipients are routed to the Hub Transport servers in the Contoso.com forest. A second cross-forest Send connector is configured for routing messages from Fourthcoffee.com to Contoso.com. When the Hub Transport servers in Contoso.com receive messages from the internal relay domain Fourthcoffee.com, they deliver messages for recipients in authoritative domains and relay messages for Internet recipients to the Edge Transport server for delivery.

QUESTION 165
A corporate environment includes Exchange Server 2010 SP1. The Exchange Server environment includes two Client Access servers, two Hub Transport servers, and two Mailbox servers on the internal network, and two Edge Transport servers in a perimeter network. An edge subscription is in place between the Hub Transport servers and the Edge Transport servers.
When an Edge Transport server fails, messages accepted by that server are not delivered.
You need to recommend a solution for ensuring that messages accepted by either Edge Transport server are attempted for delivery if either Edge Transport server fails.
What should you recommend?

A.    Enable shadow redundancy.
B.    Create a new remote domain.
C.    Create a new send connector.
D.    Enable back pressure.

Answer: A
Explanation:
Understanding Shadow Redundancy
Applies to: Exchange Server 2010 SP2
High availability strategies for Exchange have focused on the availability and recoverability of data stored in mailbox databases. When you implement a highly available solution for your Mailbox servers, the e-mail messages won’t be lost, and they can easily be recovered after a failure, after they arrive in a mailbox.
However, these strategies didn’t extend to messages while they’re in transit. If a Hub Transport server fails while processing messages and can’t be recovered, data loss could occur. As the volume of messages processed by Hub Transport servers increases, potential data loss becomes an increasing concern for administrators. Microsoft Exchange Server 2007 introduced the transport dumpster feature for the Hub Transport server role.
An Exchange 2007 Hub Transport server maintains a queue of messages delivered recently to recipients whose mailboxes are on a clustered mailbox server. When a failover is experienced, the clustered mailbox server automatically requests every Hub Transport server in the Active Directory site to resubmit mail from the transport dumpster queue. This prevents mail from being lost during the time taken for the cluster to fail over. While this does provide a basic level of transport redundancy, it’s only available for message delivery in a cluster continuous replication (CCR) environment and doesn’t address potential message loss when messages are in transit between Hub Transport and Edge Transport servers.
Exchange Server 2010 introduces the shadow redundancy feature to provide redundancy for messages for the entire time they’re in transit. The solution involves a technique similar to the transport dumpster. With shadow redundancy, the deletion of a message from the transport databases is delayed until the transport server verifies that all of the next hops for that message have completed delivery. If any of the next hops fail before reporting back successful delivery, the message is resubmitted for delivery to that next hop. Shadow redundancy provides the following benefits:
It eliminates the reliance on the state of any specific Hub Transport or Edge Transport server. As long as redundant message paths exist in your routing topology, any transport server becomes disposable.
If a transport server fails, you can remove it from production without emptying its queues or losing messages.
If you want to upgrade a Hub Transport or Edge Transport server, you can bring that server offline at any time without the risk of losing messages. It eliminates the need for storage hardware redundancy for transport servers. It consumes less bandwidth than creating duplicate copies of messages on multiple servers. The only additional network traffic generated with shadow redundancy is the exchange of discard status between transport servers. Discard status is the information each transport server maintains. It indicates when a message is ready to be discarded from the transport database.
It provides resilience and simplifies recovery from a transport server failure. Shadow redundancy is implemented by extending the SMTP service. The service extensions allow SMTP hosts to negotiate shadow redundancy support and exchange discard status for shadow messages.

QUESTION 166
Your company has offices in New York and Miami. The offices connect to each other by using a dedicated WAN link. Each office has a direct connection to the Internet. An Active Directory site exists for each office. Each office contains one Mailbox server, two Hub Transport servers, and two Client Access servers. All servers have Exchange Server 2010 Service Pack 1 (SP1) installed and run Windows Server 2008 R2.
The Mailbox servers are configured as shown in the following table.

wpsC7C6.tmp

You need to recommend a high-availability solution for the Mailbox servers that meets the following requirements:

– The mailbox databases must be automatically available if a single Mailbox server fails.
– The mailbox databases must be automatically available if the WAN link between the offices fails.
– The mailbox databases must be available if all of the Exchange servers in an office become unavailable, after an administrator performs a manual failover.

Which of the following solutions is the best recommendation? (More than one answer choice may achieve the goal. Select the BEST answer.)

A.    Add a Mailbox server to each office.
Create one database availability group (DAG).
Add all Mailbox servers to the DAG.
Add a file share witness to the Miami office.
Create a copy of each mailbox database.
B.    Add a Mailbox server to each office.
Create two database availability groups (DAGs).
Add one Mailbox server from each office to each DAG.
Add a file share witness to each office.
Create a copy of each mailbox database.
C.    Add two Mailbox servers to the Miami office.
Add one Mailbox server to the New York office.
Create two database availability groups (DAGs).
Add all of the Mailbox servers in the Miami office to one of the DAGs.
Add all of the Mailbox servers in the New York office to the other DAG.
Add a file share witness to each office.
Create a copy of each mailbox database.
D.    Add two Mailbox servers to each office.
Create one database availability group (DAG).
Add all of the Mailbox servers in the Miami office to the DAG.
Add a file share witness to the New York office.
Create a copy of each mailbox database.

Answer: B

QUESTION 167
A corporate environment will include Exchange Server 2010 in two Active Directory Domain Services (AD DS) sites.
You need to recommend a solution that provides a single connection point for all Outlook Web
App (OWA) connections.
What should you recommend?

A.    Deploy one Client Access server array for each AD DS site.
B.    Deploy one Client Access server array.
C.    Configure a hardware load balancer for the Client Access servers.
D.    Configure Autodiscover in each AD DS site for a common internal URL.

Answer: C
Explanation:
In an organization that has multiple Active Directory sites and multiple Client Access in each site, you can use Network Load Balancing (NLB) to load balance traffic proxies between the Client Access servers in each site and for users directly accessing those servers. Just deploying a load balancer isn’t enough ensure traffic is balanced effectively. You must also perform some additional configuration of the InternalURL and ExterrnalURL properties. We recommend you include only Client Access servers within the same Active Directory site in a load-balancing array. You can deploy NLB in an Internet-facing Active Directory site and in a non-Internet-facing Active Directory site.

QUESTION 168
A corporate environment will include Exchange Server 2010.
You need to recommend a solution that meets the following client access requirements:

– Automatic failover of specific client access protocols
– Distribution of client access traffic across multiple Client Access servers
– Secure Sockets Layer (SSL) session ID for clientto Client Access server affinity

What should you recommend?

A.    Deploy a Client Access server array.
B.    Deploy Microsoft Forefront Unified Access Gateway (UAG) as a reverse proxy.
C.    Deploy a hardware load balancer for the Client Access servers.
D.    Deploy Microsoft Forefront Threat Management Gateway (TMG) as a reverse proxy.

Answer: C
Explanation:
Hardware Load Balancing
If you have more than eight Client Access servers in a single Active Directory site, your organization will need a more robust load balancing solution. Although software load balancing solutions available, a hardware load balancing solution provides the most capacity solutions, see Microsoft Unified Communications Hardware Load Balancer Deployment. For more information about Exchange 2010 server solution, see Microsoft Unified Hardware Load Balancing Hardware Load Balancer Deployment.

Hardware load balancers support very high traffic throughput and can be configured to load balance in many ways. Most hardware load balancer vendors have documentation about how their product works with Exchange 2010. The simplest way to configure hardware load balancers is to create a fallback list of the be applied by the load balancer. For example, the load balancer will try cookie-based affinity first, then SSL session ID, and then source IP affinity.

QUESTION 169
A corporate environment includes a two-node Exchange Server 2010 Client Access server array.
You are designing a disaster recovery plan for the Client Access servers. The plan must meet the following requirements:

– Back up the SSL certificates.
– Back up the Windows Network Load Balancing (NLB) configuration.
– Back up only the minimum amount of data.

You need to recommend the components to back up on each Client Access server.
What should you recommend?

A.    the system state and the registry
B.    only the system state
C.    the registry and the system volume
D.    the system state and the system volume

Answer: B
Explanation:
Exchange Server 2010 Client Access Server Backup and Recovery The Exchange Server 2010 Client Access Server role is responsible for client connectivity to mailboxes. All client connection methods are provided by the Client Access server, including:
MAPI (eg connecting via Outlook on the LAN)
HTTPS (eg Outlook Web App, ActiveSync, or Outlook Anywhere) IMAP POP3
The only client connections to Mailbox server resources that the Client Access server does not provide are Outlook clients connecting to Public Folder databases. Outlook connects directly to the Mailbox server for public folders. What Needs to be Backed Up on Client Access Servers? To plan for backup and recovery of the Client Access server you should start by knowing where the server stores its configuration and data. Active Directory ?the majority of the Client Access server configuration is stored in Active Directory. For example the internal and external URL settings of the OWA virtual directory are stored in Active Directory.
Exchange 2010 Client Access server settings stored in Active Directory However not all of the settings for these Client Access server features are stored in Active Directory.
System State ?the system state of the Client Access server stores important information such as the SSL certificates installed on the server, and service configuration information (eg dependencies and startup options). If the server is a member of an Exchange 2010 CAS array the NLB configuration is also stored in the system state. Finally if there are other applications installed on the server then those will likely have settings stored in the registry as well.
File System ?because of the Client Access server’s integration with IIS there are multiple configuration files stored on the file system itself for components such as the OWA virtual directory. The IIS root config file (aka the IIS metabase) is also stored in the file system.
Planning the Client Access Server Backup
As you plan the Client Access server backup strategy there are different techniques that you can consider depending on your requirements.
Backing up Everything
A full system backup of the Exchange 2010 Client Access server, along with a working Active Directory, will have all of the required information to recover the Client Access server. Naturally this backup takes the longest to run, and will use up the most backup storage.
Backup up the Minimum

To reduce backup storage and keep the backup time frame shorter the minimum data on the Client Access server can be backed up. This involves backing up the system state of the server, and configuration files stored in the \ClientAccess path of the Exchange Server 2010 installation folder (C:\Program Files\Microsoft\Exchange Server\V14 by default).
Backing up Nothing
It may be practical to not back up the Client Access server at all if:
There are multiple, redundant Client Access servers deployed (ie Client Access Server Array)
The SSL certificates are exported or retrievable from elsewhere Customizations to the Client Access server virtual directories can be quickly reapplied using an existing script
If all of those conditions are true then the Client Access server may not need to be backed up at all.

QUESTION 170
A company deploys Exchange Server 2010. The environment includes three datacenters located in New York, Dallas and Miami. Each datacenter is configured as an Active Directory Domain Services (AD DS) site. Each site has one Client Access server, one Hub Transport server and one Mailbox server. The Mailbox servers in New York and Dallas are configured in a database availability group (DAG).
You have the following requirements:

– Ensure that mail flow is not interrupted if any one Hub Transport server fails.
– Deploy the minimum number of additional servers.

You need to recommend a solution that meets the requirements.

What should you recommend?

A.    Deploy one additional Hub Transport server in New York and one additional Hub Transport server
in Dallas.
B.    Add the Hub Transport role to the Client Access server in Miami.
C.    Deploy one additional Hub Transport server in each site.
D.    Deploy one additional Hub Transport server in Miami.
