Here's your all-new CCNA and CCENT practice exam for Friday, December 27!

Before we get to today's questions, allow me to thank you for making my CCNA Triple Threat such a huge success on Amazon!

No Kindle Required -- read them on any PC, MAC, or smartphone with the Free Kindle Apps!




My ICND1 Study Guide, ICND2 Study Guide, and Binary Math Mastery ebooks are certified Amazon Best Sellers, thanks to your support!

If you don't have yours -- grab 'em now, and get certified in 2014 with a little help from the Bulldog!

Let's get to today's practice exam!


1.  Which of the following values does EIGRP use by default to calculate routes?

A.  bandwidth

B.  load

C.  reliability

D.  MTU

E.  delay


2.  In the following command, what exactly does the "100" represent?

ip hold-time eigrp 100 50

A.  The bandwidth allowed to EIGRP.

B.  The EIGRP hold time  (Hello time).

C.  The EIGRP AS.

D.  The EIGRP hold time (Dead time).

E.  The variance setting.



3.  You're about to disable EIGRP autosummarization.   Which of the following should you expect or do afterward?


A.  The line protocol will go down briefly.

B.  The router's EIGRP adjacencies will drop.

C.  You'll need to reload the router to take effect.

D.  None of the above.


Answers right after this brief, important break!

And now -- the answers!

1: "A, E".  EIGRP will use the bandwidth and delay values by default to calculate route metrics.


2.  "C".   You have to watch EIGRP commands closely, since the Autonomous System numbers tend to pop up in almost every EIGRP-related command.  Like this one, for instance!  



3.  "B".  This is a good thing to know!   When you disable EIGRP autosummarization, that route will lose its existing EIGRP adjacencies.   If nothing else has changed, they should come back very quickly.

Thanks for taking today's free practice exam, and for making TBA part of your success story!


Always Be Passing,

Chris B.

Santa's loading his sleigh, I'm working on my new CCENT and CCNA practice exam -- coming January 13! (Hint: Huge discount that day.)

I'm also putting the finishing touches on my all-new practice exam site, which will have plenty of free practice exams for the CCENT, CCNA, CCNP, Network+, and Security+ exams...

... and much, much more. 2014's going to be the biggest year yet for TBA -- and for you!

I'm very, very lucky to do what I do for a living.

From the bottom of my heart -- thank you!  

Chris B.

Here's your all-new CCNA and CCENT Training Post for Monday, December 23!

Speaking of practice exams, my all-new CCNA and CCNP practice exam site launches in January, along with a total refresh of the main TBA website! (Finally!)


And now... today's practice exam!

1.  Under which of the following circumstances will a DUAL Query be sent in EIGRP?


A.  One is sent with every EIGRP Hello packet.

B.  An EIGRP route has gone into Passive state.

C.  A feasible successor has been lost and there is no successor.

D.  Never, because EIGRP doesn't use DUAL.

E.  A successor route has left the IP routing table and there's no feasible successor.



2.   Regarding EIGRP, OSPF, and wildcard masks, which of the following is true?

A.  Neither protocol requires this type of mask, but you can use wildcard masks with either protocol.


B.  EIGRP requires wildcard mask usage, but OSPF does not.


C.  OSPF requires you use wildcard masks, but EIGRP does not.


D.  Both protocols require the use of wildcard masks.



3.   Which of the following is true regarding EIGRP autosummarization?

A.  It's on by default.

B.  The "no auto-summary" command is a default command, written when you enter an EIGRP AS.

C.  Leaving this feature on can lead to subnet advertisement issues in your network.

D.  Under no circumstances should EIGRP autosummarization be disabled.



4.   Given the following EIGRP route entry, give the exact value we expect to see where the four Xs are, and what that value represents.

D       2.2.2.2 [XXXX /409600] via 172.23.23.2, 00:01:49, Ethernet0

And now -- the answers!

1.  "E".   EIGRP's DUAL Query process goes into action when a successor route is lost and there is no feasible successor.



2.  "C".  OSPF requires the use of wildcard masks, but EIGRP does not.  



3.  "A,C".  EIGRP autosummarization is on by default, and leaving it on can lead to some trouble with advertising subnets in your network, which in turn can lead to suboptimal routing.



4.  The "xxxx" would be 90 in this case, since this is an EIGRP internal route.  We know it's an EIGRP interal route because of the "D" routing code at the far left.

That number is the administrative distance of the routing protocol, which is a measure of believability.  If the code were "D EX", it would be an EIGRP external route, and that route would have an AD of 170.

See you Tuesday with another new practice exam!

Always Be Passing,

Chris B.

Here's your all-new CCNA  Training Post for Thursday, Dec. 19!

A new CCNP post follows later today!

Hey, I have a quick favor to ask before we get to today's questions....

... if you're planning to buy a Kindle (or anything else from Amazon), use this link to do so.  

Amazon tosses us a few cents or a few bucks when you do that, and that helps us keep our Video Boot Camp prices low!

And with six new courses coming in 2014 (no kidding), it all counts!

Kindles And More On Amazon

Thanks!  : )  Let's get to work on OSPF!



1.  What OSPF command would prevent Hello packets from being sent out a particular interface, while still allowing the network that interface resides on to be advertised to other routers?


2.  Where exactly would you configure that command?  (Don't say "On a Cisco router", that's not quite specific enough.)



3.  What is the exact command you would use on an Ethernet interface to double its default OSPF cost?






4.   You've just changed the OSPF reference bandwidth on a Cisco router.  What should you do next?


A.  Restart the router in order for the change to take effect.


B.  Restart the OSPF processes in order for the change to take effect.


C.  Ensure the reference bandwidth value you set on this router is the same on other OSPF routers in the same network.



D.  Use the default-information originate command to reset the OSPF costs.



5.  An OSPF router wants to advertise a default route to neighboring stub routers. Problem is, that router doesn't have a default route to advertise.  Which of the following single commands could you run in order to resolve this issue?


A.  default-information originate


B.  passive-interface



C.  redistribute static


D.  None of the above.





Answers right after this brief, important break!

Time to make a choice.


You can choose to put off your studies until 2014 and lose your momentum totally ...

... or you can be wise and keep hitting your studies now.

Over 7000 students are already there. Join us now!




And now -- the answers!

1 and 2:  You'd use the passive interface command to do so, and that command is configured under the OSPF routing process, not on the interface itself:

router ospf 1
    passive-interface ethernet0



3.  The default OSPF cost of an Ethernet interface is 10, so you'd use the interface-level command ip ospf cost 20.


4.  "C".  You don't have to reload the router, but you should make sure the reference bandwidth is the same on all OSPF-speaking routers in your network.  The router will give you a warning about that, and I'll show you that info in a new Video Boot Camp later today!



5.  "D".  You need this full command:

default-information originate always

The "always" allows the router to advertise a default route that it doesn't actually have.

"default-information originate" by itself will advertise a default route IF the router actually has one, and the question said the router didn't have one. (That's why route redistribution wouldn't work, either.)


Great work!  See you later today with a new Video Boot Camp and on Friday with a new practice exam!

Always Be Passing,

Chris B.

Here's your all-new CCNA and CCNP Training Post for Tuesday, December 17!

A quick word before we get started...


Do NOT let your studies slide during the holidays -- no problem with taking a little time off, but if you let your studies totally drop over the next few weeks, you're going to have a hard time getting started again in mid-January.

I've seen it happen to others.  Don't let it happen to you!

With that in mind, let's get to today's EIGRP practice exam, and I'll see you Wednesday with another new exam!

Let's get started!


1.  Let's start with the fundamentals. What routing algorithm does EIGRP use?



2.  Identify the true statements.

A. EIGRP is no longer Cisco-proprietary.

B. You can only run EIGRP on Cisco routers.

C.  The AD of an EIGRP internal route is higher than that of an EIGRP external route.

D.  An external EIGRP route is one that's been learned via route redistribution.


3.   Which of the following do potential EIGRP neighbors have to agree upon in order to become actual EIGRP neighbors?

A.  AS number

B.  They must reside on the same subnet.

C.  Area number

D.  EIGRP neighbors don't have to agree on any of these factors or values.


Answers right after this brief, important break!

Time to make a choice.

And now -- the answers!

1.   EIGRP uses DUAL to calculate routes.


2.   Checking out each choice...

A is true.  EIGRP was once Cisco-proprietary, but that's no longer true.

For that reason, B is false.

C is false.  The AD of an EIGRP External route is 170, where the AD of an EIGRP Internal route is 90.

D is true.  When EIGRP learns of a route via route redistribution, that route is marked as External.


3.   A and B.   Potential EIGRP neighbors must be in the same Autonomous System and they must reside on the same subnet.



Great work!  See you Wednesday!

Always Be Passing,

Chris B.

Here's your all-new CCNA and CCNP Training Post for Wednesday, December 11!

There's another new OSPF practice exam right below this one - tackle it when you're done here, and I'll see you Wednesday with another new practice exam!

Let's get started!


1.  Which two of the following describe link-state protocols?

A.  Routing updates sent at regularly scheduled times.


B.  Routing updates contain all known routes discovered by that protocol.


C.  Routing updates contain only the state of the links (hence the name, "link-state")


D.  Link state info is kept in a database separate from the IP routing table.



2.  What single word is used to describe an OSPF metric? 



3.  An individual LSA is refreshed how often, if it's not otherwise refreshed due to a topology change?


A.  Every 30 seconds.

B.  Every 30 minutes.

C.  Every 30 hours.

D.  Every 30 days.



4.   You want to place all router interfaces with IP addresses in the 172.12.23.0 /24 subnet into OSPF area 0, and you've configured the following network statement to do so.    

R2(config-router)# network 172.12.23.0 0.0.0.255 area 0 

Is there a problem with this statement?

A.  Nope.

B.  You're in the wrong config mode.

C.  The network mask is written incorrectly.

D.  The wildcard mask is misconfigured.

E.  The "area" value is in the wrong place in this statement.


Answers right after this brief, important break!

You have to make a choice.

And now -- the answers!

1.   "C, D".   Link-state routing updates contain information about the state of the links, and that info is kept in a database that is separate from the IP routing table.


2.  The OSPF route metric is cost.


3.  "B".  Each individual LSA is refreshed every 30 minutes.   This is on an individual basis - it's not that every LSA is refreshed at the same time.



4.  "A".  There's nothing wrong with that network statement.  The config mode is find, the wildcard mask is fine, and the area value is at the correct place in the overall statement.

Great work!  I'll see you Thursday with another practice exam along with a brand-new Video Boot Camp!

Here's your all-new CCNA and CCNP Training Post for Monday, December 9!

I strongly recommend you CCNP candidates out there take this practice exam for a refresher on fundamentals!

And just a quick word... my CCNA and CCENT ICND2 Study Guide will be out later this week!  



My CCNA and CCENT ICND1 Study Guide is already an Amazon Bestseller, with several 5-star reviews there already!



If you don't have yours yet -- grab it now, they might run out!  : ) 


(Seriously, it's really good.  And guaranteed.  And 10 bucks!)



And now, your OSPF practice exam!

1.  What number is assigned to the LSA type known as a "Network LSA", and that identifies the DR and BDR?


2.  A "DROTHER" detects a topology change on an OSPF broadcast segment.  What routers will receive notification of that change directly from that DROTHER?

A.  The DR only.

B.  The DR and BDR only.

C.  All routers on the broadcast segment.

D.  The other DROTHERS on that particular segment only.



3.  To what IP address are OSPF Hellos multicast?  (There's a hint to part of the address!)



4.   Exactly how often are OSPF Hellos multicast by DRs and BDRs residing on an OSPF broadcast network?


5.  Which of the following would NOT interfere negatively with an OSPF adjacency?


A.  The interfaces through which the adjacency is forming are on different subnets.


B.  The routers involved are using different OSPF process IDs.


C.  The routers are using different OSPF RIDs.


D.   The adjacent interfaces are using different OSPF hello and dead timers.


E.   One interface is set for OSPF stub routing and the other is not.

And now -- the answers!

1.  The Network LSA is LSA Type 2.


2.  "B".  In this scenario, the DROTHER will notify both the DR and BDR of the change.   It's then up to the DR to let any other DROTHERS on that segment know what's going on.

3.  OSPF Hello packets are multicast to 224.0.0.5.


4.  OSPF Hello packets are multicast every 10 seconds by any router on an OSPF broadcast network (not just DRs and BDRs).


5.   Going through each scenario....

"A" would interfere with the adjacency.

"B" would not, since the OSPF process ID is locally significant only.

"C" would not, since we like our routers to use different RIDs.

"D" would definitely bring an OSPF adjacency to a halt.   Interfaces must agree on OSPF Hello and Dead times in order to form and keep an adjacency.


"E" would get in the way of an adjacency as well.   If one interface is sending Hellos with the stub flag set and the other is sending Hellos with that same flag not set, no adjacency will form.

See you Tuesady with another all-new practice exam!

Here's your all-new CCNA and CCNP Training Post for Thursday, December 5!


Let's get to work!

1.  By default, how many secure addresses per port does a Cisco switch allow when port security has been enabled?


2.  What is the default security mode for port security?


3.  Port security has just closed a port on your switch due to a security violation.  What exact logical state will the interface be placed into?


4.   A Cisco switch port has port security enabled.  No secure addresses have been configured.  As a result, what secure address will be used?

A.  None, since a static address must be configured for port security to function.

B.  The next dynamically learned source MAC address.

C.  The next dynamically learned destination MAC address.

D.  One of the MAC addresses that were statically assigned to the CPU at the factory (a good reason to configure a different one!)


Answers right after this brief, important break!

You have to make a choice.

You can put off your studies until 2014 and lose your momentum totally ...

And now -- the answers!

1, 2, 3:  By default, Cisco port security will assign one secure MAC address for each port-security enabled port.  

The default security mode is shutdown, and when shutdown closes a port, the port will go into err-disabled state.  

That means that once you clear up the issue that caused the port to be closed down, you have to manually close and re-open the port.  You don't have to reload the switch, but the port won't reset on its own.

4.  "B".  If you enable port security on a port and don't assign a static secure MAC address, the next source MAC address that switch sees on an incoming frame will be the secure address.

See you Saturday with another all-new practice exam!

Hi Bulldogs!

Apologies on the slight delay -- here's the brand-new CCNA and CCENT Video Boot Camp I mentioned yesterday!

There's a lot of important lab work in this one, so let's get right to it!

Chris B.







Tuesday, December 03, 2013


Here's your all-new CCNA and CCNP Training Post for Tuesday, December 3!

There's a new practice exam here for you now, and I'll have a new Video Boot Camp on this exam's subject for you later today!


Before we get to today's practice exam, just a quick preview...

.... later this month, I'll release my all-new CCNA and CCENT practice exam!

I've been asked to write a practice exam for years -- and here it is!

It's not "just another practice exam" - it's a true training experience.  

Video questions, voice questions, exclusive training videos -- the works, and for a LOT less than other practice exams!

When it's released, my blog readers get THE lowest price!




Now on to today's first exam:

All of today's questions deal with the following Cisco command line output. 


Click on the image to enlarge, and let's get started!





1.   What command displays that output?


2.   Right now, all of the values are at zero.  (But you knew that.)   When the Frame Relay connection is working correctly, which two of those values should you expect to see increment?


3.   There's one particular counter in that output that would indicate a problem if it's incrementing.  Which counter is that?


Answers right after this brief message!


You can put off your studies until 2014...

... or you can be wise and keep hitting your studies now.

My CCNA Video Boot Camp is the best way to keep your success momentum rolling!

You receive over 27 hours of downloadable, info-packed CCENT and CCNA instruction from yours truly for just $44!





Now let's get to those answers....


1.  That's the output of a very important Frame Relay troubleshooting command, show frame-relay lmi.


2.  When all is well with the LMI and there's no mismatch, you should expect to see both counters on the next-to-last line increment -- num status enq. sent and num status msgs Rcvd.


3.  Timeouts are rarely a good thing, and they're really bad here.  If the Num Status Timeouts counter starts incrementing, that means we have an LMI mismatch and the line protocol is going to go down very shortly.


Be sure to watch the video in this post for a lab on live Cisco routers so you can see all of this in action --  I'll post that video later on Tuesday.   See you then!


Chris B.
