It's Saturday, August 8, and here are the answers to yesterday's Cisco practice exam questions!



Coming later this weekend - a new CCNA certification exam over on the main site, along with a CCNP BSCI exam and a new CCNA Security tutorial. Watch the blog over the weekend for links!


Check the blog posts from yesterday and today for more free practice exams and tutorials!


CCNA Certification And CCENT Certification:

It's a classic question, but you gotta know these by heart. What are the three RFC 1918 private address ranges? Include the masks in your answer.

Answer:

Class A: 10.0.0.0 /8


Class B: 172.16.0.0 /12 (watch that one, it's not /16)


Class C: 192.168.0.0 /16 (watch that one also, it's not /24)



CCNA Security Certification / CCNP ISCW Exam:

How can you configure SDM to preview the commands before delivering them to the router, and also give you a confirmation prompt when you leave SDM?



Answer: I personally check Preferences in SDM every time I use it, and I recommend you do the same. Before proceeding to the Configuration section, go to the upper-left corner of the initial SDM window and select Preferences, as shown here:








Then you can edit these three prefs to your heart's delight! (The following illustration was trimmed to fit Blogger.)

CCNP / ONT Exam:

In the following line, a service policy is being applied - but to what?

R1(config-cp)#service-policy input NTP_POLICE

Answer: The config-cp prompt indicates that we're applying the service policy directly to the Control Plane, so this must be a CoPP configuration.
