CCENT And CCNA Flash Card Practice Exam It's nice to share, so share and Google +1 this exam! :)  As always, my Flash Card questions give you no multiple choice answers.  (Neither will a Cisco router or switch!) A quick tease -- I'll have 700 of these for you to access on your phone, PC, or just about anything else later this summer for a VERY reasonable price. Tease over.  Let's get the job done! Join over 50,000 happy Bulldogs in my CCNA, CCNP, and Security courses on Udemy ! Some free, some paid, all great!  Follow this banner to see the full list of courses, and there are some SERIOUS discounts on the paid courses in today's practice exam post! (Free courses will not be further discounted.) 1.  You have four routers on an OSPF broadcast network.  There are no issues with adjacencies or timers.  Once the network has converged, how many routers will have full adjacencies with all other routers on that segment? 2.  Of our EIGRP friend

Here's a new CCNP SWITCH practice exam for you! Let's hit these flashcard questions hard, and when you're done here, be sure to use these additional free CCNP SWITCH tutorials to help you nail the exam and earn your CCNP! No need to put your answers in the form of a question, but if you want to hear Alex's voice in your head, feel free! 1.  This command globally enables DHCP Snooping on a Cisco switch. 2.  The full interface-level command that enables DHCP Snooping on a particular interface and confirms the port is indeed trustworthy. 3.  When dealing with STP defaults, a port's path cost of 19 indicates you're working with this port speed. 4.  It's the default STP priority of a Cisco switch. 5.  Of loop guard, root guard, and port security, the Cisco switch security feature that can result in a port entering the "root-inconsistent" state. Answers and today's video righ

CCNA And CCNP In-Depth Lab: Today: Advanced, real-world usage of the IP ROUTE command. Like it?  Google +1 it. Got it?  Good!  : )  --  Chris B. In an earlier CCNA and CCNP Command Discussion, we saw the fundamentals of the ip route command in action. Today, we'll see an often-overlooked option of this command that can serve you well in real-world networking... ... and it'll also reinforce an important Cisco routing concept or two. Let's get started! In networking, we'll take as much redundancy as we can get. It's not enough to have one loop-free path from "A" to "B", we want a backup path in place so if the primary path goes down for any reason, the backup path can smoothly (we hope!) go into action. (If you were waiting for the "but", it's on the way.) But on occasion, networking can get just a bit complicated.  For example, today's network! Simple enough, right?   Welll...... In real-world netw

CCNA And CCNP In-Depth Lab: The Three (Three?) ADs Of EIGRP Your only cost for this huge CCNA and CCNP tutorial is a share or a Google +1.  Thanks!   -- Chris B. A few basics of admin distance before we get EIGRP-specific: The administrative distance of a route doesn't really have anything to do with "distance".  It's actually a measurement of the believability of a route source.  The lower the AD, the more believable the source is. The AD range is 0 - 255, with 255 indicating an untrustworthy source. Simple enough, right?  Right!   But.... (and you knew that was coming) .... there are some additional details that go along with ADs that we need to know for our CCNA and CCNP exams as well as avoiding confusion when working with real-world networks. Take the admin distances of EIGRP routes, for example.  And yes, I said "distances", because there are multiple EIGRP admin distances -- and not just the two you might already know about. Let&#
