MS Exchange 2013 interview questions and answers :

1 .What is the new features in Exchange server 2013.

New Managed Store completely rewritten in C# was introduced. 

Exchange Administration Center (EAC)

Exchange architecture revisions:

Exchange 2013 has just two roles: Client Access server role and Mailbox server role. The Mailbox server role includes all the typical server components (including unified messaging), and the Client Access server role handles all the authentication, redirection, and proxy services. You can deploy Exchange 2013 with an Exchange 2010 Edge Transport server role and 2013 Edge role.

Modern public folders:

DLP (data loss prevention): DLP is new in Exchange 2013's transport rules, but it's also a continuation of Mail Tips in that it warns users when they may be violating policies meant to prevent disclosure of sensitive data ETC.

  1. What are the features removed from Exchange 2013 compared to legacy version of Exchange server.

 Exchange Management console was removed.

Extensible Storage Engine (ESE) streaming backup APIs

User Datagram Protocol (UDP) notifications

Document Access, Message Flag, Spell Check, Search folder are removed from Outlook Web App

Client authentication using Integrated Windows authentication (NTLM) for POP3 and IMAP4 users

  1. Where Exchange Server stores the Exchange related information in Active Directory

Domain Partition – Mail enable recipient, groups and contact related to domain level are stored

Configuration Partition – Stores the Exchange configuration information like, policies, global settings, address list, connecters and it contains the information related to forest level

Schema Partition – stores the Exchange specific classes and attributes

  1. What are the types of Active Directory deployment that server supported in Exchange Server 2013 deployment.

Single Forest

Multi Forest

Resource Forest

  1. Difference between Exchange 2013 on-premises, Online, office 365 and Windows Azure Power shell.

The Exchange Online is able to manage the users and permission of Exchange service. The Office 365 (Windows Azure AD) is to manage the whole Office 365 service. Windows Azure can use to manage users, domain and other things which will affect the whole Office 365 service. It is not able to be used to manage Exchange service, Lync service and SharePoint service. To manage Exchange service, you need to use Exchange Online PowerShell to perform the activity.

  1. What is purpose of running prepare schema and prepare AD switches in Exchange server 2013

Prepare Schema – After running the Prepare Schema switch, the Active directory will contain the classes and attributes required to support Exchange environment

Prepare AD – after running the Prepare AD switch, new container will be created to hold the details of the information from server to databases to connectors. This process also created universal security groups to manage Exchange and sets appropriate permissions on objects to allow them to be managed

  1. What is the purpose of Auto discover service & Availability Service?

The Auto discover service does the following:

Automatically configures user profile settings for clients running Microsoft Office Outlook 2007, Outlook 2010, or Outlook 2013, as well as supported mobile phones.

Provides access to Exchange features for Outlook 2007, Outlook 2010, or Outlook 2013 clients that are connected to your Exchange messaging environment.

Uses a user's email address and password to provide profile settings to Outlook 2007, Outlook 2010, or

Outlook 2013 clients and supported mobile phones. If the Outlook client is joined to a domain, the user's domain account is used.

Availability service—The Availability service is the replacement for Free/Busy functionality responsible for making a user’s calendar availability visible to other users making meeting requests.

Retrieve current free/busy information for Exchange 2013 mailboxes

Retrieve current free/busy information from other Exchange 2013 organizations

Retrieve published free/busy information from public folders for mailboxes on servers that have previous versions of Exchange

  1. Explain the list of files will be there under Exchange 2013 database folder

.edb File - A mailbox database is stored as an Exchange database (.edb) file.

Checkpoint file .chk, keeps track of which transactional logs moves into database files. Keep on check the log file entering the database in a current order

Transactional log – eoo.log file which write the current transactions into transactional logs. If it reaches 1 MB, it will rename the log file into E00000001.log

Temp.EDB – Temporary database file, which will process the transactional logs that are to be to write in .EDB Database file

.JRS – Reserved Log files – if the size of the disk is full and you can’t write any mails as transactional logs these files will help into action

  1. What you mean by database portability in exchange 2013

Database portability is a feature that enables a Microsoft Exchange Server 2013 mailbox database to be moved to or mounted on any other Mailbox server in the same organization running Exchange 2013 that has databases with the same database schema version. Mailbox databases from previous versions of Exchange can't be moved to a Mailbox server running Exchange 2013. By using database portability, reliability is improved by removing several error-prone, manual steps from the recovery processes. In addition, database portability reduces the overall recovery times for various failure scenarios.

  1. What is the purpose of DAC?

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.

  1. How to check backup is completed successfully for the Exchange 2013 mailbox database.

Get-Mailboxdatabase -status | Format-List Identity, *backup*

  1. What is the purpose of site mailbox in Exchange server 2013.

Site mailbox requires Exchange 2013 and Sharepoint 2013 which has the functionally of shared storage through an Exchange 2013 mailbox for email messages and a SharePoint 2013 site for documents, and a management interface that addresses provisioning.

  1. What is the change on public folder in Exchange Server 2013.

Public folder uses specially designed mailboxes to store both the public folder hierarchy and the content. This also means that there’s no longer a public folder database. High availability for the public folder mailboxes is provided by a database availability group (DAG).

  1. What is S/MIME certificate and how to send email using S/MIME certificate

S/MIME (Secure/Multipurpose Internet Mail Extensions)used for users to encrypt outgoing messages and attachments so that only intended recipients who have a digital identification (ID), also known as a certificate, can read them. With S/MIME, users can digitally sign a message, which provides the recipients with a way to verify the identity of the sender and that the message hasn't been tampered with.Setting up S/MIME for Outlook Web App needs Exchange 2013 SP1 which can be configured using Powershell command   :   Get-SmimeConfig and Set-SmimeConfig

  1. What is RBAC and list out the management role present in Exchange Server 2013.

Role Based Access Control (RBAC) is the permissions model used in Microsoft Exchange Server 2013. With RBAC, you don't need to modify and manage access control lists (ACLs), which was done in Exchange Server 2007. ACLs created several challenges in Exchange 2007, such as modifying ACLs without causing unintended consequences, maintaining ACL modifications through upgrades, and troubleshooting problems that occurred due to using ACLs in a nonstandard way.

Below roles you can manage.

Organization Management

 View-Only Organization Management

 Recipient Management

 UM Management

 Discovery Management

 Records Management

 Server Management

 Help Desk

 Hygiene Management

 Compliance Management

 Public Folder Management

 Delegated Setup

  1. What is the service needed to move mailbox in Exchange 2013.

Move requests are processed by two services:

 Microsoft Exchange Mailbox Replication service (MRS)

 Microsoft Exchange Mailbox Replication Proxy (MRSProxy) service

  1. What is the purpose of File Share Witness?

A witness server is a server outside a DAG that's used to achieve and maintain quorum when the DAG has an even number of members. DAGs with an odd number of members don't use a witness server. All DAGs with an even number of members must use a witness server. The witness server can be any computer running Windows Server. There is no requirement that the version of the Windows Server operating system of the witness server matches the operating system used by the DAG members.

  1. List out the different type of quorum model used in Exchange server 2013.

Even - Node and File Share Majority quorum mode

Odd - Majority quorum mode

DAGs with an even number of members use the failover cluster's Node and File Share Majority quorum mode, which employs an external witness server that acts as a tie-breaker. In this quorum mode, each DAG member gets a vote. In addition, the witness server is used to provide one DAG member with a weighted vote (for example, it gets two votes instead of one). The cluster quorum data is stored by default on the system disk of each member of the DAG, and is kept consistent across those disks. However, a copy of the quorum data isn't stored on the witness server. A file on the witness server is used to keep track of which member has the most updated copy of the data, but the witness server doesn't have a copy of the cluster quorum data. In this mode, a majority of the voters (the DAG members plus the witness server) must be operational and able to communicate with each other to maintain quorum. If a majority of the voters can't communicate with each other, the DAG's underlying cluster loses quorum, and the DAG will require administrator intervention to become operational again.

DAGs with an odd number of members use the failover cluster's Node Majority quorum mode. In this mode, each member gets a vote, and each member's local system disk is used to store the cluster quorum data. If the configuration of the DAG changes, that change is reflected across the different disks. The change is only considered to have been committed and made persistent if that change is made to the disks on half the members (rounding down) plus one. For

Example, in a five-member DAG, the change must be made on two plus one members, or three member’s total.

  1. Difference between Primary Active Manager and Standby Active Manager

Primary Active Manager (PAM)

 

An Active Manager role held by a single DAG member at any given time that is responsible for responding to failures an initiating corrective action in the form of a database or server failover.

Standby Active Manager (SAM)

 An Active Manager role held by all DAG members that do not hold the PAM role that is responsible for monitoring for local failures and responding to queries from CAS and Hub as to the location of the user’s mailbox database.

  1. What is the purpose of safety-net and transport dumpster.

Transport dumpster helps to protect against data loss by maintaining a queue of successfully delivered messages that hadn't replicated to the passive mailbox database copies in the DAG. When a mailbox database or server failure required the promotion of an out-of-date copy of the mailbox database, the messages in the transport dumpster were automatically resubmitted to the new active copy of the mailbox database.

The transport dumpster has been improved in Exchange 2013 and is now called Safety Net.

Similarity between Safety Net and transport dumpster in Exchange 2010:

Safety Net is a queue that's associated with the Transport service on a Mailbox server. This queue stores copies of messages that were successfully processed by the server. You can specify how long Safety Net stores copies of the successfully processed messages before they expire and are automatically deleted. The default is 2 days.
