Good day

,
I am presently unemployed, trying hard through home study (can't afford college learning to pass these exams, so hopefully I can get some work as soon as possible, to meet family committments, I 'm sure it's the same for most people, it's great to have this support network available.
I have heard that in the exam the some commands like config t, show ipconfig /all etc are not permitted in the test simulation software.
Is this peoples experience?
How do you view a switch/routers configuration detail, when you can't use config t, show ipconfig /all?
How can you see which type of a router or switch is used in a diagram?
Can you do simulation test exam type questions and practice some lab exam type simulation questions for these exams?
Thank you have a nice weekend.
