By: Chris Bryant
To help you prepare for total success on your Cisco certification exams, here’s a new set of CCNA, CCNP, Security, and CCENT practice exam questions! Answers are at the bottom of the page. Enjoy!
What command results in the following output?
00:11:37: RIP: received v2 update from 18.104.22.168 on Serial0
00:11:37: 22.214.171.124/24 via 0.0.0.0 in 1 hops
What's the basic purpose of the logging synchronous command?
CCNA Security Certification / CCNP ISCW Exam:
When configuring a basic firewall in SDM, what are the three options for the preconfigured security levels? Can you create your own custom security levels?
CCNP Certification / BSCI Exam:
In the following output, describe....
1. Why we would use this command in the first place
2. The meaning of "100"
3. The meaning of "300"
4. The default setting for this particular value, and what we're changing it to.
R1(config-if)#ip bandwidth-percent eigrp 100 300
CCNP Certification / BCMSN Exam:
What router redundancy protocol is defined by RFC 2281?
CCNP / ONT Exam:
IntServ uses RSVP, but DiffServ does not. What does DiffServ use in place of RSVP?
Here are the answers!
CCNA: Answer: That's the output of debug ip rip.
CCENT: Answer: When the router wants you to know something, it wants you to know right now. If the router sends a message to the console while you're entering a command, by default the router will interrupt your work to show you this message.
In the following example, I opened a Serial interface, which will always result in at least two messages relating to the physical and logical state of the interface. I started typing a sentence immediately after I opened the interface to show you what happens. I've bolded the sentence I was entering.
R1#so here i am
4d04h: %SYS-5-CONFIG_I: Configured from console by consoletyp
4d04h: %LINK-3-UPDOWN: Interface Serial0, changed state to uping and
4d04h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to upi've been interrupted quite badly!
4d04h: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial0, changed state to down
This may seen trivial, but when you have a long command entry interrupted by a console message, you'll wonder how to prevent that from happening. (After you stop yelling at the router, that is.)
By configuring the logging synchronous command on the console port, you're telling the router to hold such messages until it detects no input from the keyboard and no other output from the router, such as a show command's output.
R1(config)#line console 0
synchronous Synchronized message output
