The -null built-in map

The -null built-in map is always used in association with a mount point and tells automount not to mount any remote filesystems to this mount point on the local host. This excludes any mounts to the associated mount point that may be specified:

on the automount command line.

in any master or direct maps read by automount. (Indirect maps do not include a mount point and so are not relevant to this discussion.)

Here is an example of -null map usage on the automount command line:

automount /usr/bin -null

In this example, automount will ignore all instructions to mount remote filesystems to /usr/bin. See ``Using built-in automount maps'' for further examples of using the -null map.

Q. Is there a recertification policy for the MCITP certification?

We no longer require a "refresh" or recertification of the MCITP certification within three years. To better meet our customers� needs, we now retire a certification when mainstream support for the related technology phases out. If you earned an MCITP certification before the policy change, no action is required�the updated policy applies to your certification, which will remain valid until mainstream support for the related technology ends.

Q. Does MCSA equate to MCITP: Server Administrator and does MCSE equate to MCITP: Enterprise Administrator?

No, not exactly. The MCITP on Windows Server 2008 certification requires a new skill set�in some cases, a more robust one�that differs from the skill set needed for MCSA and MCSE certifications.

MCITP: Server Administrator certification covers more operations-related job skills than the MCSA certification.
MCITP: Enterprise Administrator maps to an actual job role profile, whereas the MCSE certification does not. The latter combines technology and job skills.

Q. Are the MCTS and MCITP certifications replacing the MCSA and MCSE certifications?

No. The MCSA and MCSE certifications are not being replaced. There is no change to the Microsoft Windows 2000 Server and Windows Server 2003 tracks and certifications. The MCTS and MCITP certifications are for Windows Server 2008.

Q. Am I a Microsoft Certified Professional (MCP) if I earn an MCITP certification?

Yes and no. The term MCP is used both as a general term for all Microsoft Certified Professionals and as the name of a certification. As an MCITP, you become part of the Microsoft Certified Professional community, with access to all related benefits, information, and activities. You do not earn a certification titled "MCP." You should use the MCITP certification on your resum� and in business collateral, which indicates your specialty and shows that you are a member of the MCP community.

Q. How long will my certification be valid?

All Microsoft Certified Technology Specialist (MCTS), Microsoft Certified IT Professional (MCITP), and Microsoft Certified Professional Developer (MCPD) certifications retire when Microsoft discontinues mainstream support for the related technology. After a certification retires, it still appears on your transcript but is listed as "inactive." In most cases, an upgrade path is available for people who have that certification, which allows them to demonstrate their skills on the newest version of the technology without completing all exams associated with the new certification. The following certifications will not be retired: Microsoft Certified Systems Engineer (MCSE), Microsoft Certified Systems Administrator (MCSA), Microsoft Certified Desktop Support Technician (MCDST), Microsoft Certified Database Administrator (MCDBA), Microsoft Certified Solution Developer (MCSD), and Microsoft Certified Applications Developer (MCAD).
