Thoughts on the afternoon questions of the network administrator of the soft exam in the first half of 2013

Generally speaking, the afternoon question is relatively simple:

One is integrated cabling.

The second is to build WEB and DNS servers.

Third, network topology.

Fourth, ASP+ACCESS.

For me, ASP has less contact with ACCESS, but fortunately, it is a simple web code and common sense problems in ACCESS database. It is estimated that network engineers will be more difficult, this part still needs to be strengthened!

Summarize the problems that you are not proficient in:

1, a PTR record in a domain name resolution server, usually used in a special domain to perform an address-to-name image reverse lookup. Each record provides simple data to point to some other location in the domain name space, usually in a forward lookup area. It can be understood as a reverse DNS parsing record.

The primary key (primary key) in the main access database. There is only one primary key in a table. The primary key can also be called the primary key. A primary key can consist of either a field or multiple fields. There can be only one primary key in a table, and the primary key is used to uniquely identify a record in the table.

3, the code that calls the ACCESS database in ASP.
