TCP ports and sockets ??????
|
|
|
| Can anyone tell me what level of detail questions on TCP ports and sockets will be on the exam?
I ask this for several reasons.
1) The 50-407 version of the Sybex book seems to cover this is detail, but the 50-507 Cisco book doesn't seem to do so. Also the Sybex book seems to not make much sense if you compare the text to the appendix
2) If the exam is only looking to see if we know about what sockets and ports are, I don't want to waste time studying this in detail, and will devote more time to other areas that I still need to work on. But on the other hand, if I need to know the info, then Study, Study

| You can be sure that ports are going to be on the exam in various ways. Not only are you going to be asked about "well known ports" 1023 and below as specified by rfc 1700 but in other ways as well. For example, you'll see it in regards to "access lists" and determing what kind of traffic is permited or denied based on port numbers. While you don't have to know them all, you should know that FTP uses port 21, Telnet uses 23 and WWW;HTTP uses 80 maybe you'll need TFTP which uses port 69.
You want to remember these well. This is about what you can expect to see. | |

| Thanks.
That helps ALOT. Remembering 4 commonly used Ports is much easier than knowing them all. Plus I kind of suspected that the objective is not to know them all.
