Database administrators are often responsible for managing and maintaining the various components of SQL Server clustering. The clustering technique is used in a variety of applications and the questions asked of a candidate in an interview will vary depending on the scope of the job. To help ensure that you are fully prepared for such an interview, it is important to have an understanding of the types of SQL Server clustering interview questions that you may be asked. In this blog post, we will take a look at some of the common questions employers may ask about SQL Server clustering. We will discuss the types of questions to expect, proper preparation, and how to answer the questions in a professional and informed manner. By understanding the types of questions that may be asked, you can create the best possible impression and demonstrate to potential employers that you possess the knowledge and expertise necessary to handle the responsibilities of a SQL Server clustering administrator.

SQL Server Interview Questions and Answers | What is SQL Server Clustering
Choose Take Offline from the popup menu item when you right-click the SQL Server Group in the Cluster Administrator.
A distinct server name is used to publish groups to clients on the network that include resources such as an IP address and a network name in addition to other resources. They are referred to as virtual servers because to clients, these groups appear as individual servers. Users can access virtual servers’ applications and services in the same way they can physical servers’ applications and services. They don’t need to be aware that they are joining a cluster, and they don’t even need to know which node they are attached to.

| As all of us need every service should be 24 into 7 and available every time we need that. So every services provider need to technically strong. TO overcome this problem new concept comes into picture that is failover cluster. It is group of independent computers that work together to increase the availability of applications and services. Here each clustered server connected by cables and by software. And this clustered server called nodes. If one cluste |
| r nodes fails then another node begins to work. It is good technique which is not dependent on single server. |
What is SQL Server AlwaysOn?
Since SQL Server 2012, Microsoft has referred to high availability and disaster recovery solutions as AlwaysOn. There are currently two features included in AlwaysOn. For SQL Server databases, these two features support high availability and disaster recovery:
The new features added to SQL Server 2012 to support data high availability and disaster recovery are called AGs as opposed to SQL Server AlwaysOn FCIs, which are SQL Server clustered instances. With the assistance of the Availability Group, we can combine each set of databases into a single entity and perform a failover all at once.
A failover cluster that is configured so that both cluster nodes are active at all times is called an “Active-Active cluster.” That is, one instance of SQL Server runs continuously on each node, and when a node fails, both instances continue to run on that node until the failed node is brought back online (after the problem that caused the node failure has been resolved). The instance is then transferred back to the chosen node.
A failover cluster configured so that only one cluster node is active at any given time is known as an “Active-Passive cluster.” The other node, known as the Passive Node, is constantly online but inactive while it waits for the Active Node to fail. At that point, the Passive Node assumes control of the SQL Server Services and becomes the Active Node, with the previous Active Node becoming a Passive Node.
FAQ
What is clustering in SQL Server?
A group of two or more physical servers (nodes) connected by a local area network (LAN) and each hosting a SQL server instance with the same access to shared storage is known as a SQL Server cluster.
How many IP required for SQL Server clustering?
Your SAP system has six IP addresses and corresponding host names in a properly configured cluster with two nodes. Each cluster node has two IP addresses: one for the cluster and one for the liveCache cluster group.
What are the prerequisites of SQL Server clustering?
A failover cluster’s nodes must all run the same operating system edition and version and be of the same platform, either 32-bit or 64-bit. Additionally, 64-bit Windows operating systems and 64-bit hardware must be used to install 64-bit SQL Server editions.
How many types of clusters are there in SQL Server?
You have a choice between single-instance clustering and multiple-instance clustering (referred to in SQL Server 7). 0 as active/passive and active/active clustering, respectively).
