Windows Interview Questions
- What’s the role of http.sys in IIS? It is the point of contact for all incoming HTTP requests. It listens for requests and queues them until they are all processed, no more queues are available, or the Web server is shut down.
- Where’s ASP cache located on IIS 6.0? On disk, as opposed to memory, as it used to be in IIS 5.
- What is socket pooling? Non-blocking socket usage, introduced in IIS 6.0. More than one application can use a given socket.
- Describe the process of clustering with Windows 2003 Server when a new node is added. As a node goes online, it searches for other nodes to join by polling the designated internal network. In this way, all nodes are notified of the new node’s existence. If other nodes cannot be found on a preexisting cluster, the new node takes control of the quorum resources residing on the shared disk that contains state and configuration data.
- What applications are not capable of performing in Windows 2003 Server clusters? The ones written exclusively for NetBEUI and IPX.
- What’s a heartbeat? Communication processes between the nodes designed to ensure node’s health.
- What’s a threshold in clustered environment? The number of times a restart is attempted, when the node fails.
- You need to change and admin password on a clustered Windows box, but that requires rebooting the cluster, doesn’t it? No, it doesn’t. In 2003 environment you can do that via cluster.exe utility which does not require rebooting the entire cluster.
- For the document of size 1 MB, what size would you expect the index to be with Indexing Service? 150-300 KB, 15-30% is a reasonable expectation.
- Doesn’t the Indexing Service introduce a security flaw when allowing access to the index? No, because users can only view the indices of documents and folders that they have permissions for.
- What’s the typical size of the index? Less then 100K documents - up to 128 MB. More than that - 256+ MB.
