السلام عليكم

الاخ الكريم اشكرك جزيل الشكر على الموقع هذا

http://www.certyourself.com/exams/comptia/...aplus1/exam.cgi

وقد وجدت به العديد من الاسئلة الجميلة وان كانو يعاودون الرجوع لها مرات عدة

ولكن اعتقد ان هناك بعض الاسئلة مغالط فى الاجابات

مثلا

يسال الموققع عن تحميل سيستم ديسك فما الطريقة

وهذا هو نص السوال

1. What is the fastest method to create a bootable disk?

Enter FORMAT A:/U/S with any disk in drive A:

Enter SYS C: A: with a previously formatted disk in drive A:

Diskcopy another bootable disk

Enter SYS A: with a previously formatted disk in drive A:

------------

اعتقد ان الاجابة السليمة تكون

Enter SYS C: A: with a previously formatted disk in drive A

ولكن للعجب انهم اختارو الاجابة التالية

Enter SYS A: with a previously formatted disk in drive A:

فمن اين ياخذ الديسك ملفات السيستم

وكثير منها كذالك

ولكن لك الشكر على هذا السيت واعتقد ان هناك كثير منه موجود وبالاخص فى موضوع الشبكات

والله اعلم
