Interview Question for active diectory and exchange

Interview Question for active diectory and exchange



What is RUS?

The Recipient Update Service (RUS) is responsible for creating and maintaining E-Mail Addresses in your Exchange Organization. The Recipient Update Service creates an Entry (Recipient Update Service (Enterprise Configuration)) for the entire Exchange Organization for modifying objects in the Configuration Container Partition in Active Directory and one RUS for every Exchange enabled Domain in this Forest.

Which contains have in Exchange 2003 Default Recipient policy?

Exchange Server 2003 there is one Recipient Policy called Default Policy. The Default Policy contains Proxy addresses for the Default SMTP domain and one address for X.400.

  1. What is the maximum number of exchange sites in a domain?
  2. what is the maximum number of Exchange sites can you run in a forest?
  3. What is the maximum number of containers can you create in an exchange server enterprise?
  4. what is bridgehead server

In Exchange 2000, a bridgehead server is a connection point from a routing group to another routing group, remote system, or other external system

5 What is AD

Active Directory

The directory service for Windows 2000 Server. It stores information about objects on the network and makes this information available for authorized administrators and users. Active Directory gives network users access to permitted resources anywhere on the network using a single logon process. It provides administrators with an intuitive hierarchical view of the network and a single point of administration for all network objects.

What is Administrative group?

administrative group

A collection of Active Directory objects that are grouped together for the purpose of permissions management. An administrative group can contain policies, routing groups, public folder hierarchies, servers, and chat networks. The content of an administrative group depends on choices you make during installation.

What is circular login?

Circular logging

A method of logging transactions in Microsoft Web Storage System in which earlier log files are overwritten after the transactions in the log file have been committed to the database.

What is distribution list?

distribution list

A group of recipients created to expedite mass mailing of messages and other information. When e-mail is sent to a distribution list, all members of that list receive a copy of the message

What is Domain?

domain

A grouping of servers and other network objects under a single name. Domains provide the following benefits:

You can group objects into domains to help reflect your company's organization in your computer network.

Each domain stores only the information about the objects located in that domain. By partitioning the directory information this way, the Active Directory scales up to as many objects as you need to store information about on your network.

Each domain is an administrative boundarythis means that security policies and settings (such as administrative rights, security policies, and security descriptors) do not cross from one domain to another. Note, however, that the domains within a forest are not security boundaries that guarantee isolation from each other. Only the forest constitues a security boundary.

What is DC

A computer running Windows 2000 Server that manages user access to a network, which includes logging on, authentication, and access to Active Directory and shared resources.

What is DHCP

Dynamic Host Configuration Protocol

(DHCP) A protocol for assigning Internet Protocol (IP) addresses to computers and other devices on a TCP/IP network. Dynamic addressing permits a computer to have a different address each time it logs on to a network

What is front-end & back-end server?

front-end and back-end architecture

An Exchange architecture in which clients access a set of protocol servers (the front end) for collaboration information, and these servers in turn request data from separate servers (the back end). A front-end and back-end architecture provides a scalable, single point of contact for all data requests.

front-end server

A server that receives requests from clients and relays them to the appropriate back-end server.See also: back-end server

What is global address list?

(GAL) A list containing all Exchange users, contacts, groups, conferencing resources, and public folders in an organization. This list is retrieved from the global catalog servers in Active Directory and is used by Outlook clients to address messages or find information about recipients within the organization.

What is GC?

A server that holds a complete replica of the configuration and schema naming contexts for the forest, a complete replica of the domain naming context in which the server is installed, and a partial replica of all other domains in the forest. The global catalog is the central repository for information about objects in the forest.

What is infrastructure master ?

A domain controller that updates cross-domain group-to-user references to reflect a user s new name. The infrastructure master updates these references locally and uses replication to bring all other replicas of the domain up to date. If the infrastructure master is unavailable, these updates are delayed.

What is Lightweight Directory Access Protocol ?

(LDAP) A network protocol designed to work on TCP/IP stacks to extract information from a hierarchical directory such as X.500. It is useful for searching through data to find a particular piece of information.

What is mail exchanger resource record ?

(MX resource record) A Domain Name System (DNS) record that specifies a mail exchange server for a DNS domain name. A mail exchange server is a host that either processes or forwards mail for the DNS domain name. Processing the mail means either delivering it to the addressee or passing it to a different type of mail transport. Forwarding the mail means sending it to its final destination server, sending it using Simple Mail Transfer Protocol (SMTP) to another mail exchange server that is closer to the final destination, or queuing it for a specified amount of time.

What is mail-enabled ?

An Active Directory object that has at least one e-mail address defined. If the user is mail-enabled, the user has an associated e-mail address, but does not have an associated Exchange mailbox

What is message transfer agent ?

(MTA) An Exchange component that routes messages to other Exchange MTAs, information stores, connectors, and third-party gateways. Also referred to as X.400 protocol in Exchange 2000 System Manager.

What is namespace?

namespace

A set of names associated with a domain or forest that identifies objects that belong to the domain or forest. A DNS name creates a namespace; for example, microsoft.com.

What is recipient, recipient Policy, Recipient Update Service.?

recipient

An Active Directory object that is mail-enabled, mailbox-enabled, or that can receive e-mail. A recipient is an object within Active Directory that can take advantage of Exchange functionality.

recipient policy

Policies that are applied to mail-enabled objects to generate e-mail addresses. They can be defined to apply to thousands of users, groups, and contacts in Active Directory by using a Lightweight Directory Access Protocol (LDAP) query interface in a single operation.

Recipient Update Service

An Exchange 2000 service that updates the recipient objects within a domain with specific types of information. You can schedule appropriate intervals to update the recipient objects. For example, this service updates recipient objects with address list membership and e-mail addresses at intervals scheduled by the administrator.

What is RAID?

Redundant array of independent disks

(RAID) A mechanism for storing identical data on multiple disks for redundancy, improved performance, and increased mean time between failures (MTBF). RAID provides fault tolerance and appears to the operating system as a single logical drive.

What is Routing Group, routing group bridgehead server & routing group connector ?

routing group

A collection of Exchange servers that have full-time, reliable connections. Messages sent between any two servers within a routing group go directly from source to destination. Similar to administrative groups, routing groups are optional and are not visible in System Manager unless they are enabled.

routing group bridgehead server

A server within a routing group that exchanges directory updates with a server in another routing group.

routing group connector

A connector that specifies the connection of a local routing group to a server in a remote routing group. It also specifies the local bridgehead server, if any, and the connection cost, schedule, and other configuration properties.

What is schema & schema master?

Schema

A logical model for data; an organizational framework. Schema defines the universe of objects that can be stored in Active Directory. For each object class, the schema defines what attributes an instance of the class must have, what additional attributes it can have, and what object class can be a parent of the current object class.

Schema master

The domain controller that performs write operations to the directory schema. Schema updates are replicated from the schema master to all other domain controllers in the forest. Only the schema master domain controller can perform this task.

What is SID?

Security identifier

(SID) A data structure of variable length that uniquely identifies user, group, service, and computer accounts within a forest. Every account is issued a SID when the account is first created. Access control mechanisms in Windows 2000 identify security principals by SID rather than by name.

What is SRS?

A directory service (similar to the directory used in Exchange Server 5.5) implemented in Exchange 2000 to allow integration with Exchange 5.x sites that use both remote procedure call (RPC) and mail-based replication. Site Replication Service works with Active Directory Connector (ADC) to provide replication services from Active Directory to the Exchange 5.x Directory Service.

What is smart host?

smart host

A designated server through which Exchange routes all outgoing messages. The smart host then makes the remote connection. If a smart host is designated, the Exchange server only needs to transmit to the smart host, instead of repeatedly contacting the domain until a connection is made. Also known as a relay host.

What is transaction log file?

A file that maintains a record of every message stored in a storage group and provides fault tolerance in the event that a database must be restored.

What is universal group?

A Windows 2000 group available only in native mode that is valid anywhere in a forest. A universal group appears in the global catalog but contains primarily global groups from domains in a forest. This is the simplest form of group and can contain other universal groups, global groups, and users.See also: domain local group

What is zone?

In a DNS database, a zone is a contiguous portion of the DNS tree that is administered as a single separate entity by a DNS server. The zone contains resource records for all the names within the zone

What is DomainPrep:

DomainPrep creates the groups and permissions necessary for Exchange servers to read and modify user attributes in Active Directory. You must run DomainPrep before installing your first Exchange server in a domain. While the DomainPrep Setup switch may seem to do the same thing as ForestPrep on the surface, its purpose is different. Whereas ForestPrep prepared the schema and configuration partitions of Active Directory, DomainPrep prepares the domain partition. Another key difference is that while ForestPrep is run once (in the forest root domain) for the entire forest, DomainPrep must be run in each of the following domains:

  • The forest root domain
  • All domains that will contain Exchange Server 2003
  • All domains that will contain Exchange mailbox-enabled objects (users and groups), even if the domain does not have its own Exchange Server 2003 server

The DomainPrep switch creates the groups and permissions required by Exchange Server 2003. Two security groups are created by DomainPrep:

  • Exchange Enterprise Servers: A domain local group that contains all Exchange servers running in the forest.
  • Exchange Domain Servers: A global group that contains all Exchange servers running in the domain you have selected.

To run DomainPrep, you must use a user account that is a member of the Domain Admins group in the local domain.

What is ForestPrep?

Exchange 2003 ForestPrep extends the Active Directory schema to include Exchange-specific classes and attributes. ForestPrep also creates the container object for the Exchange organization in Active Directory. The schema extensions supplied with Exchange 2003 are a superset of those supplied with Exchange 2000.

In short, ForestPrep prepares the Active Directory forest and the schema for the installation of Exchange Server 2003. ForestPrep must be run only once in the whole forest. ForestPrep extends the schema to include Exchange specific classes and attributes.
