Microsoft Internet Information Server Technology & Digital Applications 4 — Questions and Answers
Question 1: Which IIS log format field records the time taken to service a request in milliseconds?
- sc-bytes
- time-taken (Correct answer)
- cs-uri-stem
- s-computername
Correct answer: time-taken
The time-taken field in W3C Extended log format records the elapsed time in milliseconds from when IIS received the request to when the last byte was sent.
Question 2: In IIS, what does SNI (Server Name Indication) enable?
- Faster SSL handshakes
- Hosting multiple SSL certificates on a single IP address and port (Correct answer)
- Certificate auto-renewal
- Mutual TLS authentication
Correct answer: Hosting multiple SSL certificates on a single IP address and port
SNI is a TLS extension that allows the client to specify the hostname during the handshake, enabling IIS to present the correct SSL certificate for multiple sites on one IP.
Question 3: What is the role of the IIS 'Output Caching' feature?
- Stores user session data in memory
- Caches the response output of dynamic pages to reduce repeated processing (Correct answer)
- Compresses static files on disk
- Buffers log writes to improve disk performance
Correct answer: Caches the response output of dynamic pages to reduce repeated processing
Output Caching stores rendered responses in memory so subsequent identical requests are served from cache without re-executing application code.
Question 4: Which IIS authentication mechanism uses Kerberos tickets and NTLM as fallback without transmitting passwords?
- Basic Authentication
- Digest Authentication
- Windows Authentication (Negotiate) (Correct answer)
- Anonymous Authentication
Correct answer: Windows Authentication (Negotiate)
Windows Authentication with the Negotiate provider uses Kerberos first, falling back to NTLM, and never sends the actual password over the network.
Question 5: What is the maximum number of worker processes that can be assigned to a single IIS application pool using Web Garden configuration?
- 1
- 4
- Limited only by server hardware and licensing (Correct answer)
- 10
Correct answer: Limited only by server hardware and licensing
A Web Garden allows multiple worker processes per application pool, with the practical limit determined by available CPU cores and server resources.
Question 6: Which IIS module handles the mapping of request URLs to physical file paths on disk?
- HTTP Logging Module
- Static File Module (Correct answer)
- Static Compression Module
- DefaultDocument Module
Correct answer: Static File Module
The Static File Module serves files directly from disk by resolving the URL to a physical file path and streaming the file contents as the HTTP response.
Question 7: In the context of IIS and ASP.NET, what does the 'Integrated Pipeline Mode' provide compared to 'Classic Mode'?
- Faster static file serving
- ASP.NET modules participate in the full IIS request pipeline for all content types (Correct answer)
- Automatic HTTPS redirection
- Improved FTP transfer speeds
Correct answer: ASP.NET modules participate in the full IIS request pipeline for all content types
Integrated Pipeline Mode unifies the ASP.NET and IIS request pipelines, allowing ASP.NET HTTP modules to run for all requests, not just managed content.
