B. Incorrect: Only the Windows Server 2003 family includes application recycling
as a feature of IIS. This feature automatically restarts IIS applications and ensures
that active users do not get disconnected during this process.
C. Incorrect: Only the Windows Server 2003 and the Windows 2000 Server families
include bandwidth throttling as a feature of IIS. This feature limits the amount of
traffic that IIS can generate. It is useful for ensuring that Web services do not consume
an Internet connection, thereby reducing performance for users and other
Web sites.
D. Incorrect: Only the Windows Server 2003 and the Windows 2000 Server families
include IP address and domain name restrictions. Using this capability, it is possible
to allow or disallow users based on their source IP address. Alternatively, filtering
can be done based on the results of a reverse DNS lookup of the source IP
address.
E. Correct: The version of IIS included with Windows XP Professional does support
content expiration. This feature improves the performance of the Web site by
instructing the client and proxy servers to cache specified content. Cached content
can be retrieved from the local system, without issuing a request to the Web
server. Content expiration must be enabled only on content that does not change
frequently, to ensure clients always retrieve an up-to-date version of the content.
4. Correct Answers: A
A. Correct: If Kevin logs on interactively, he has Change permission to the files in
the IIS home directory. However, because Kevin can access the Web content only
using HTTP, IIS controls access and limits rights to Read access only. NTFS permissions
do not override limitations enforced by IIS. Instead, effective permissions are
always equal to the lesser access allowed by IIS and NTFS. As a result, the Full
Control provided by the file permissions has no effect.
B. Incorrect: Kevin is not capable of updating files using HTTP because IIS does
not have Write access enabled.
C. Incorrect: Kevin is able to read files in the home directory because IIS has read
access enabled. However, write access is not enabled. NTFS permissions do not
override limitations enforced by IIS. Instead, effective permissions are always
equal to the lesser access allowed by IIS and NTFS. As a result, the Full Control
provided by the file permissions has no effect.
D. Incorrect: Kevin is able to read files in the home directory because IIS has read
access enabled. However, write access is not enabled. Full control also allows for
file permissions to be changed, which is never possible when access to files is
through IIS. NTFS permissions do not override limitations enforced by IIS. Instead,
effective permissions are always equal to the lesser access allowed by IIS and
NTFS. As a result, the Full Control provided by the file permissions has no effect.
