Question 1

What does the IIS 'Failed Request Tracing' (FREB) feature capture?

Accepted Answer

Detailed trace events for requests that match defined failure conditions

Answer

Failed Request Tracing records a detailed event trace (including module pipeline stages, timing, and headers) for requests that meet specified failure criteria such as status codes or time thresholds.

Question 2

Which process isolation model does IIS use by default to protect the web server from application failures?

Accepted Answer

Worker process isolation where each application pool runs in its own w3wp.exe

Answer

By default, each IIS application pool runs in a separate w3wp.exe worker process, so a crash in one application does not affect other sites or the IIS service itself.

Question 3

What is the purpose of the 'maxAllowedContentLength' setting in IIS Request Filtering?

Accepted Answer

It sets the maximum size of an HTTP request body in bytes that IIS will accept

Answer

maxAllowedContentLength (under requestFiltering/requestLimits) sets the maximum allowed size of the request entity body; requests exceeding this limit are rejected with a 413 error.

Question 4

In IIS, which HTTP status code is returned when a client is denied access due to IP address restrictions?

Accepted Answer

403 Forbidden

Answer

IIS returns 403 Forbidden when a client's IP address is blocked by the IP Address and Domain Restrictions feature, indicating the server understood the request but refuses to fulfill it.

Question 5

What is the function of the HTTP.sys kernel-mode driver in IIS?

Accepted Answer

It handles low-level HTTP request parsing and response caching in the Windows kernel

Answer

HTTP.sys is a kernel-mode driver that listens on the network stack, performs HTTP request parsing, and implements a kernel-mode response cache to improve performance.
