اخواني هذه هي الاسئلة الخاطئة في ال pass4sure وتصحيحها وهو منقول عن موضوع للأخ يحيى لكن كون الملف الموضوع مرفوع على 4shared فأحببت أن أكتبه كتابة ليتمكن الجميع من قراءته ولكن لا ننسى فضل الاخ يحيى في هذا الموضوع
Q271: assuming only one vlan in the exhibit, which switch is acting as the root bridge?
pass4sure answer: A)switch 1
correct answer: C) switch 3
explanation: the root bridge cannot contain a blocked ports so switch 3 is the correct answer.
Q337:
refer to the exhibit. which route will be found in the routing table of the main router?
pass4sure answer: B) R 192.168.2.0/24 via 192.168.255.26, 00:00:24, serial 0/0
correct answer : C) R 192.168.255.16[120/1] via 192.168.255.26, 00:00:24, serial 0/1
explanation:
as i think because 192.168.2.0 is in two hop from serial 0/0 so it must be [120/2] not [120/1] but in answer (C) the ip 192.168.255.16 is one hop from serial 0/1 so it may be the correct answer
Q342) refer to the exhibit. a network technician enters the following line into the router. Tidmore1(config)#access-list 106 deny tcp 192.168.254.0 0.0.0.255 any www, what is the effect of this configuration?
pass3sure answer: B)all traffic from the 192.168.254.0 lan to the internet is permitted.
correct answer: A) the change has no effect on the packets being filtered
explanation:
if the technician enters the that line after those lines in the exhibit the line has no effect on the packets because we have the command permit any any. so the answer is (A) but if the technician entered the lines begining with the first line and then enters the lines in the exhibit so the answer would be differ and as i think it will be (C).
Q350)refer to the exhibit. a network associate has the internetwork that is shown in the exhibitm but has failed to configure routing properly. which configuration will allow all hosts on the branch LAN to access resources on the HQ LAN with the least impact on router processing and wan bandwidth?
Pass4sure answer: (D)
correct answer : (A)
explanation: here we have two router that they are connecting using the WAN network and because we need to access the HQ LAN using the branch lan in least impact on router processing and WAN bandwidth so the static route will be the most accurate solution to this case because it has the least administrative distance and it also did not need any extra calculations that may be used for OSPF or other dynamic routing algorithm and it reserve the WAN bandwidth better than other routing algorithms.
اخواني هذا عبارة عن مجهود شخصي في شرح حلول الأسئلة فان اصبت فمن الله وان اخطأت فمن نفسي. لا اله الا انت سبحانك اني كنت من الظالمين
ارجو ممن لديه اي تعديل على الاجابات او يرى ان اجاباتي خاطئة أن يخبرني وسأغير الحل ان شاء الله
