8) Explain the term DAG (Data Availability Group)?
DAG or Data Availability Group is a framework build is MS Exchange 2013. It is a group of upto 16 mailbox server that hosts a set of databases and provides automatic database level recovery due to failure of servers of databases.
10) Explain how message is delivered to the mailbox database in Exchange 2013?
In exchange 2013, after the message reaches the target mailbox server in the destination AD site, the transport service avails SMTP to carry the message to the mailbox. After that, using RPC, Transport Service delivers the message to the local mailbox.
1) Mention what are the new features in MS Exchange 2013?
3) Mention what are the roles in MS exchange 2013?
In MS exchange 2013, there are two roles Client Access Server and Mailbox Server.
There are a few different troubleshooting methods that I would use if an Exchange Server went down. First, I would check to see if there are any error messages in the Event Viewer that could give me a clue as to what might be wrong. Next, I would check to see if all of the services required for Exchange to run are still running. If they are not, I would start them up again. Finally, I would check to see if there are any updates or patches that need to be installed on the Exchange Server.
The architecture of Exchange Server 2016 is based on a modular design that consists of a set of independent server roles, which can be deployed together in a variety of ways to meet the specific needs of an organization. The server roles are Client Access, Mailbox, Edge Transport, and Unified Messaging. Client Access handles all client connections to the Exchange server, while the Mailbox role stores all the mailbox data. The Edge Transport role provides protection against spam and malware, and the Unified Messaging role provides voicemail and email integration.
The client access server is responsible for handling all client connections to a Microsoft Exchange server. This includes handling all requests for data, such as email messages, as well as managing any updates that need to be made to the data on the server. The client access server is the only server that clients should need to connect to in order to access their Exchange data.
There are pros and cons to both hosted and local exchange servers. With a hosted server, you are relying on the hosting company to keep your server up and running, which can be a risk if they are not reliable. However, hosted servers can be a good option for small businesses that don’t have the resources to manage a local server. Local exchange servers give you more control over your server, but they can be more expensive and require more maintenance.
When you have multiple servers set up for email delivery, each server is configured to check for new messages at a set interval. When a new message arrives, the server will check the message header to see if it is addressed to a user on that server. If it is, the server will deliver the message to the user’s mailbox. If the message is not addressed to a user on that server, the server will check the header to see where the message should be delivered next and forward it accordingly.
