The answers are: A, C, & D.
Hopefully, I can explain this to make sense. A /20 subnet requires 4094 total hosts and/or 16 subnets. Start first w/ your subnets by counting by increments of 16 (0, 16, 32, 48, etc.). The 10.1.160.XXX subnet starts at 10.1.160.0 and ends at 10.1.175.255, therefore the subnet address would be 10.1.160.0 and the broadcast address would be 10.1.175.255 making everything in between possible host addresses. As you can see in the list of choices, your broadcast and subnet addresses are listed and an IP from the NEXT subnet (10.1.176.1). Hope that helps.
Which IP addresses are valid for hosts belonging to the 10.1.160.0/20 subnet...Choose 3
A_10.1.168.0
B_10.1.176.1
C_10.1.174.255
D_10.1.160.255
E_10.1.160.0
F_10.1.175.255
I understand why option E cannot be correct because it is the network but how can I quickly compute the correct answers when the increment is 16? What am I missing to quickly solve this on a test? I had no problems getting the other subnet questions correct so I know my method is correct. Puzzled & any help is certainly appreciated!
I think router$show ip interface is correct answer. HELP!!
Good luck to u all~!
Thanks.
it is valid and 90% of the questions from it
study them well and get tested
:)
FYI...to whoever is going to download vce file on the upper-right of this screen here, it's version dated June 25th, 2012 and it will be $24.99 if you want to buy for a regular version like I had before, and don't make s mistake like me (DO NOT UPDATE!!). I don't have J-O-B, no money, I need to focus on my study, now I got distracted with this issue.
Could someone please...if you have saved the .VCE older version somewhere please share, help to rescue me with this issue (Please DO NOT include virus!!)
Thank you so much.
sure there not, just memorize them and you should be fine, if you concerned that you can't pass the .vce exam, don't worry, just answer all the questions correctly and you will pass, except for Drag questions and sims :)
Restore your windows the day before this miss happened with you and you will be fine :)
Need help please! for some reason my VCE file became "Trial COPY" after it asked me to "Update Now" or cancel. After the program Window closed, I opened it again just like I normally would, then this window pops up, asking if I'd like to update to a newer version, so I clicked on "update now". Now, I can only view 5 questions at a time, unlike 339 or my choice. I clicked on Download IT (2.7 MB), it is the same thing. I went to cnet to download from there, got virus came with it. Unintalled/reinstall, clean up virus mess, still got trial COPY. Can someone please kindly advise me, I'm stuck! Thank you so much ahead.
yaaaaaaaaaaaaaaay
:)
B. Port security;
D. VLAN's
and may be
E. PoE
Why A. Layer 3 support needed in access layer??
thus if the answer for C was something like 'status of POST testing' , than you would have a valid argument.
hope this clears things up, but I know what you mean...just got to read carefully.
