CCNA Certification And CCENT Certification:
What's the net effect of the following two commands?
line con 0
exec-timeout 0 0
logging synchronous
Answer: Setting the exec-timeout command to zero minutes and zero seconds effectively disables the console line timeout, since that's where we're configuring the command. The logging synchronous command prevents console messages from appearing while you're entering a command; the message will appear after you hit Enter.
Both of these are great Cisco home lab commands, and they just might pop up on an exam or two as well!

Short answer: What is the Nyquist Theorem?
Answer: We need a guideline for how many voice samples to take, and the Nyquist Theorem is that guideline. According to this theorem, the sampling rate should be twice as high as the highest frequency of the signal for the signal to be accurately rebuilt at the destination.I'll have new questions for you later today! I've also posted answers to the three CCNP exams I posted on the website, along with a brand-new CCNA/CCNP home lab video on configuring a frame relay switch - look for links to all these great features in today's other blog posts!
