All of yesterday's questions were short answer.
CCNA Certification And CCENT Certification:
List the three locations from which a Cisco router attempts to load a valid IOS image during the boot process. And list them in order! :)
1. Flash memory (the default).
2. A TFTP server. (Trivial File Transfer Protocol)
3. Read-Only Memory (ROM)
Short answer: Define the term man-in-the-middle attack.
Answer: A network intruder opens a connection with two separate devices, with each device thinking they're communicating with the other device rather than the intruder.
In the world of WPA , what is "Michael", and what does it / he do?
Answer: WPA uses a Message Integrity Check (MIC), sometimes called "Michael", to protect against replay attacks, spoofing, and the man-in-the-middle attacks we discussed in the previous question.
What is "comfort noise"? Is it desirable? How do we enable it, if it's not enabled by default?
Comfort noise is artificial noise that's "pumped in" when the parties involved in the call go silent. It's very low, but it is there, which prevents you from thinking you've been cut off - and again, from personal experience, comfort noise really does make the conversation more comfortable.
Comfort noise is not on by default on a Cisco router, but it's easy enough to enable:
CCNP Certification / BSCI Exam:
In what particular situation would you find yourself using the OSPF command summary-address? Your answer should include the OSPF router type(s) that can run that command.
Answer: Use the summary-address command to summarize non-OSPF routes being redistributed into an OSPF process. From that description, you know only an ASBR can use this command.
CCNP Certification / BCMSN Exam:
When a Cisco switch port receives a dynamic VLAN assignment, what is autoenabled on that port at the same time?
Answer: An interesting default of VMPS is that when a port receives a dynamic VLAN assignment, Portfast is automatically enabled for that port!
I'll have more questions for you later today!
In the meantime, spend some time at my Cisco CCNA, CCNP, and CCENT tutorials page - that page has links to over 200 Cisco practice exams, tutorials, articles, and videos are on the way!
