Certificates like these shouldn't be used for getting a step in the door, rather they should help YOU learn more about a specific area, so that you have the confidence to apply for jobs within that area and know what you're talking about.
Too many people do these certificates to get the piece of paper. That's not what they are about, they are about learning more about a product. Simply as that IMO....
Pick an area you'd like to get into, and pick a course to help you learn as much as possible in that area. From there, you can start applying for jobs etc etc, as you have the knowledge required. Some employers considering the MCSE / CCNA a benefit still, but not many.
