Be sure to check today and yesterday's blog posts for links to new CCNA Security tutorials, and I'll have several new CCNA and CCNP exams posted over the weekend with links here in the blog as well!
CCNA Certification And CCENT Certification:
What command resulted in the following output?
R3# ?
All possible debugging has been turned off
Answer: The command was undebug all, or "u all" for short!
CCNA Security Certification / CCNP ISCW Exam:
With regards to the IOS Firewall Feature Set, what is "generic inspection"? What methods of generic inspection are available?
Answer: If you want to inspect all TCP and/or UDP connections, you can specify TCP and/or UDP as the inspected protocol in the ip inspect command rather than a more-specific entry. This is generic inspection. The options are TCP and UDP.
CCNA Wireless:
What version of EAP involves a RADIUS server and strong two-way authentication between client and server?
Answer: Cisco's Lightweight Extensible Authentication Protocol (LEAP). The RADIUS server will authenticate the client, and then the client will authenticate the RADIUS server, resulting in strong two-way authentication.
Describe briefly which countries generally prefer the linear quantization method, and which ones generally prefer the logarithmic method.
Answer: Linear is primarily used in the Unites States, and logarithmic is primarily used everywhere else!
CCNP Certification / BSCI Exam:
What command network service or protocol uses the reserved IP address 224.0.0.12?
Answer: HSRP uses that reserved address.
CCNP Certification / BCMSN Exam:
After you resolve the issue that resulted in the following console output, what should you do next?
05:06:04: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/7, puttingFa0/7 in err-disable state
05:06:04: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 000f.f773.ed20 on port FastEthernet0/7.
Answer: You need to bring the port out of err-disabled state, so just shut and reopen the port after resolving the issue - which in this case, of course, is a port-security violation.
What part do access points play in the Cisco Self-Healing Network?
Answer: When an AP is lost, the CiscoWorks Wireless LAN Solution Engine (WLSE) will tell that AP's neighbors to increase their cell coverage, which allows the users who were connected to the now-lost AP to still connect to the wireless network.
More questions, practice exams, and Cisco tutorials to come over the weekend!
To your success,
