Job interview questions-1
“Gangsters are not define by how low your jeans fall by your waist but more of how your jeans stands up to their expectations. – American Gangster 2007, the movie”
I recently wondered about some of the technical questions for interviews that we usually face….. Yes, my company now has a lot of turnover of human resources recently due to various reasons. Since I am in charge of the windows platform, I was wondering about some of the windows technology questions that usually interviewers would ask. This topic would be a good blogging questions or prompter.
Me, myself, I haven’t really got really tough technical questions in an interview. So I can’t speak from experience. But here is where the Big Wide Internet comes in handy. Anyone who is a system admin, system designer, IT architect, IT specialist would know this next name that I am going to mention. He is a very very famous name within the IT community especially in the windows domain. He is from Israel, and is one of the two who holds, Windows Server System – Exchange Server MVP in Israel. He has done various reviews of books and his site, generates about 16, 000 hits per week! He is Daniel Petri. Daniel if you are reading, I am a fan!
Anyway, in his site, he has stated some of the questions that could be asked if you are a MCSE certified and looking for a system admin job. Its pretty haunting list that some of the stuff I don’t know how to answer.. But google came to my rescue. But as my fellow blogger, WingLoon mentioned, doing this and providing answers to all Daniel’s questions might not be helpful since some of the readers might just memorize the answers and be ready. My answers are in no way, the final and correct answers per say. I might even quote the wrong answers. Here is where you as readers could contribute to the list and answers.
So here it goes:
1. What is an AD?
AD is called Active Directory. Active Directory is basically a directory service that is used in a windows platform group called domain. It unifies management and the maintainability of a large group of objects like computers, servers and users. Its also a database that can be queried and is hierarchical, replicated, and extensible. Basically in the windows server that is responsible of the AD maintenance which is called Domain Controller, there is a file where is database is populated, its called NTDS.dit.
2. What is LDAP?
LDAP stands for Lightweight Directory Access Protocol. In plain and simple terms, its a database whereby it has all the details of all of organizations, individuals, and other resources such as files and devices in a network, whether on the Internet or on a corporate intranet,” and whether or not you know the domain name, IP address, or geographic whereabouts. An LDAP directory can be distributed among many servers on a network, then replicated and synchronized regularly. An LDAP server is also known as a Directory System Agent (DSA). Its a not a relational database. Outlook and other email programs uses LDAP to search for a recipient in an organization. Does AD has LDAP capabilities? Yes, AD adhere to the standard LDAP protocol (defined in RFC 2251). If you use any LDAP capable tool to query AD, it works. If you’ve ever searched for information using the Active Directory Users & Computers MMC snap-in, you’ve already seen an LDAP search in action, working behind the scenes to retrieve the information you requested.
adfind -b dc=mycompany,dc=com -s subtree -f “(&(objectCategory=person)(objectClass=user)(samAccountName=j*))”
3. Can you connect Active Directory to other 3rd-party Directory Services? Name a few options.
The only ones I know off, is eDirectory services from Novell. I don’t have any much info on this at this moment. If you guys know of anything please do let me know in the comment section. Thanks.
