| Do client access array names need to be included on the SAN cert? |
|
Definition
| The FQDN of each RPC CA array is only used by internal Outlook and don’t need to be included on the SAN list in the certificate as RPC traffic doesn’t use or require a certificate for it to be encrypted. Also does not need to be (and shouldn't be) listed in external DNS. |

| How did Exchange Outlook Anywhere clients connect? |

| What are three benefits of the RPC Client Access Server in Exchange 2010? |
|
Definition
- with MAPI and directory connections moved to the Client Access Server role in the middle tier layer, Exchange now has a single common path through which all data access occurs
- having a single common path for all data access, will allow for more concurrent connections and mailboxes per mailbox server. In Exchange 2007 a Mailbox server could handle 64.000 connections compared to Exchange 2010 which will increase that number to a 250.000 RPC context handle limit.
-better client experience during switch-over and fail-overs when you have deployed a highly available solution that makes use of the new Database Availability Group (DAG) HA feature (30 second disconnection vs. upward of 30 minutes in 2007) |

| What change must be made to the default RPC settings in Exchange 2010 to allow Outlook 2003 clients to connect to Exchange 2010 client access servers? |
|
Definition
You must set the "encryptionRequired" parameter to false. Here is the powershell: Set-RpcClientAccess –Server –EncryptionRequired $false
Alternatively, you could set the RPC encryption in the Outlook 2003 client to enabled. |
|
|
Term
| If you are globally disabling RPC encryption, where would you do this? |
|
Definition
| on BOTH the CAS servers and the mailbox servers. This is because public folder connections still go to the mailbox server's RPC client access service. If mailbox and CAS roles are colocated, it only has to be set once. |

| In Windows NLB, what is the difference between unicast and multicast mode? |
|
Definition
| In unicast, the MAC addresses of the cluster members will be changed to a virtual MAC address. In Multicast mode, a virtual MAC address is added, but the original addresses are retained. Unicast is prefereable for Exchange, but if you are virtualizing with VMware you should use multi-cast mode. |

Best Effort: (with Best Effort the database will mount no matter the copy queue length. Be careful with this setting as you could loose a lot of mailbox data!)
Best Availability (this is default): (with Best Availbility the database will mount automatically as long as the copy queue length is less than or equal to 12. If the copy queue length is more than 12, the database will not be able to mount) |

| What is the primary active manager (PAM)? |
|
Definition
| PAM is the Active Manager in a DAG that decides which copies will be active and passive. PAM is responsible for getting topology change notifications and reacting to server failures. The DAG member that holds the PAM role is always the member that currently owns the cluster quorum resource (default cluster group). If the server that owns the cluster quorum resource fails, the PAM role automatically moves to a surviving server that takes ownership of the cluster quorum resource. In addition, if you need to take the server that hosts the cluster quorum resource offline for maintenance or an upgrade, you must first move the PAM to another server in the DAG |
|
|
Term
| What is the standby active manager (SAM)? |
|
Definition
| The SAM provides information on which server hosts the active copy of a mailbox database to other components of Exchange that are running an Active Manager client component (for example, RPC Client Access service or Hub Transport server). The SAM detects failures of local databases and the local Information Store. It reacts to failures by asking the PAM to initiate a failover (if the database is replicated). A SAM doesn't determine the target of failover, nor does it update a database’s location state in the PAM. It will access the active database copy location state to answer queries for the active copy of the database that it receives. |
|
|
Term
| What actions does the active manager take to recover from a failure in a replicated mailbox database? |
|
Definition
1.Active Manager detects the failure.
2.The PAM runs an internal algorithm called best copy selection (BCS).
3.A process called attempt copy last logs (ACLL) occurs, which tries to copy any missing log files from the server that hosted the active database copy prior to the failover.
4.Once the ACLL process has completed, the PAM issues a mount request to the Microsoft Exchange Information Store via remote procedure call (RPC). At this point, either:
a.The database mounts and is made available to clients; or
b.The database does not mount, and PAM performs steps 2-4 on the next best copy (if one is available). |

|
Definition
a hunt group is defined as a set of extension numbers that are grouped as a single unit. When an incoming call is received, the PBX or IP PBX uses the hunt group to "hunt" for an available or open line, extension, or channel that can be used to receive the call.
Hunt groups are used to efficiently distribute calls into or out of a specific unit. For example, a PBX or IP PBX might be configured to have 10 extension numbers for a sales department. The 10 sales extension numbers would be configured as one hunt group.
A UM IP gateway is associated with an AD UM hunt group, which together establishes a link between an IP gateway hardware device and a UM dial plan. |
