Here's your all-new CCNA and CCNP Training Post for Tuesday, November 26!


Many thanks for making my CCNA And CCENT ICND 1 Study Guide the #1 Kindle Best Seller in the Technology / Protocols section!

Don't have yours yet?  Grab it today!

(And thanks for the +1s in Google -- all of us here at TBA really appreciate them!)





Today's CCNA / CCENT Practice Exam Topic:  "Fundamentals Of Switching"

Let's get to it!   A little warmup first....


1.   The receipt of an "unknown unicast" frame results in which of the following actions by a Cisco switch?

A.  flood

B.  filter

C.  frame

D.  multicast




2.  Host A sends a frame addressed to Host B.   After the switch between those two devices receives that frame, the switch sends a copy of that frame out every single port except the one it came in on.

Host B successfully receives the frame and immediately responds to host A.

Assuming normal switch operation, which of the following are true of the frame sent from Host A to Host B?

Choose ALL that apply.


A.  That frame was an unknown unicast.

B.  The frame was flooded by the switch.

C.  The switch filtered the frame.

D.  The frame was a multicast.

E.   The frame was a broadcast.


3.  Match the Cisco switch processing method with the phrase that describes it.

The methods: 

Cut-through


Store-and-forward

Fragment-free

A.  No error detection capabilities

B.  High level of error detection

C.  The "middle ground" of error detection among these three methods


We'll get to the answers right after this incredibly 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.  "A".  An "unknown unicast" sounds like a contradiction in terms, but the "unknown" refers to the fact that the switch doesn't have an entry for this frame's unicast destination in its MAC table.  Therefore, that frame's going to be flooded.


2.  A, B.  This frame was a unknown unicast, and the switch flooded it.

How do we know it wasn't a broadcast frame?   The first line of the question mentions "... a frame addressed to Host B", which makes the frame a unicast.


3.  Cut-through switching has no error detection capabilities, store-and-forward has the greatest error detection capabilities of the three, and fragment-free is the middle ground.   

Fragment-free switching has some error-detection capabilities, but not as great as store-and-forward.

Be sure to scroll down in the blog for more practice exams, and I'll see you later today with a brand-new video!

See you then!

Here's your CCNP SWITCH and TSHOOT Practice Exam Post for Sunday, November 24!

Today's post includes one of the most popular videos I've ever created -- and it just happen to cover today's practice exam topic in depth!

Let's dive right in!

Today's Topic:  Root Guard

1.  A port with Root Guard enabled receives an "inferior BPDU".   What will the state of that port be 15 seconds after that BPDU arrives on the port?

A.   Normal operation will continue.

B.   "err-disabled"

C.   "port-inconsistent"

D.   "shutdown"



2.    Root Guard can be configured on what switches in your Cisco network?

A.  The root switch only.

B.  The root and secondary root switches only.

C.  Any switches you like.

D.  Any switches except the root and secondary root.



3.   On what basis is Root Guard enabled?

A.  per-port

B.  per-VLAN

C.  All ports or no ports

D.  All VLANs or no VLANs 


I'll have the answers for you right after this quick message!

It's time for you to join us - and you can start my CCNP SWITCH course in minutes for just $44!


Join us today - click this banner or the link, and let's get started on your CCNP SWITCH pass!





And now... the answers!

1.  "A".  Root Guard will take action when a superior BPDU is received, but will do nothing when an inferior BPDU comes in.


2.  "C".  Root Guard can be configured on any switches you'd like to run it on.


3.   "A".  You'll enable Root Guard on a per-port basis.


Here's a great video where you can see Root Guard in action!  Enjoy, and I'll see you Monday with more!

Thanks for putting up with the sporadic blog posts this week - had a little extra dental work done, and now I'm back at it!

I've got two videos on the way for all of you later today Friday -- and one's a bit of a rant. Might cause some waves.  We'll see.

Right now, let's head to today's CCNA and CCENT practice exam - and be sure to check out Udemy's "Early Black Friday" price of $38 on my CCNA Video Boot Camp!

It will NOT be that low again.  Ever.  Sign up now and save some dough!

See you there!

Join us right now by clicking this banner, and take advantage of the special Black Friday price - it's even lower than the price on the banner!





Success on the CCENT and CCNA exams is all about the fundamentals -- and so it today's free CCNA practice exam!

1.  Of TCP and UDP, which uses a "cumulative ack scheme"?

A.  TCP only.

B.  UDP only.

C.  Both TCP and UDP.

D.  Neither one.


2.    Which of the following best describes the overall process of the UDP three-way handshake?

A.  SYN, SYN/ACK, ACK

B.  ACK, SYN, SYN/ACK

C.  SYN, ACK, SYN

D.  SYN, SYN, ACK

E.  None of the above.


3.   Fill in the blank:  UDP's advantage over TCP is that UDP has less ________.



4.   Which of the following describe TCP?  Choose all that apply.

A.  Guarantees delivery of segments

B.  Performs error detection

C.  Performs windowing

D.  Does not have sequencing number capability

E.  Runs at L3 of the OSI model

The answers right after this great big THANK YOU!   

Like I said above -- thank you for making my CCNA And CCENT ICND1 Study Guide an Amazon Bestseller in the Technology section!

Grab your copy today for less than 10 bucks!




And now... the answers revealed!

1.   The correct answer is "A".  Only TCP uses a cumulative acknowledgement scheme.


2.   The right answer is "E", because UDP doesn't have a three-way handshake.  (TCP does, though.)

3.   UDP has less overhead than TCP, and that's UDP's main advantage over TCP.

4.   A, B, and C.   TCP guarantees segment delivery, it performs error detection, and performs windowing.   D is false because TCP does have sequence numbers, and E is false because TCP runs at L4 of the OSI model.

That's it for now!   See you later today with those two new videos!

Today's CCNA / CCENT Practice Exam Topic:  "Intro To Networking"

Let's get to it!


1.   Which OSI layer ensures the remote communications partner is available? 


2.  Which of the following accurately describes the FCS?

A.  Runs at Layer 3 of the OSI model

B.  Operates at the Data Link layer of the OSI model

C.  The recipient of the frame detects the error

D.  The sender of the frame detects the error, which in turn saves valuable bandwidth.



3.  Which of the following best describes the capabilities of the Frame Check Sequence?

A.  It performs error recovery but not detection.

B.  The FCS can perform both error detection and recovery.

C.  The FCS can detect an error, but it's not responsible for recovery.

D.  The FCS can perform neither error detection nor recovery.

We'll get to the answers right after this incredibly brief message!


Join over 6700 happy Bulldogs in my CCNA Video Boot Camp!

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.  Making sure the remote partner is available is the job of the Application layer.


2.  B, C.  The Frame Check Sequence runs at the Data Link layer, and it's the recipient of the frame that actually performs the error detection.


3.  "C".  The previous question gave you a hint!  The FCS can aid in error detection, but it doesn't perform error recovery.  

Be sure to scroll down in the blog for more practice exams, and I'll see you Monday night with a very important CCNA 200-120 video!

See you then!

A CCNA practice exam like you've never seen.....

... because there's never been one like this.  

Coming very soon -- only from TBA!

Friday, November 15, 2013






Here's your CCNP SWITCH Training Post for Friday, November 15!

Let's get right to today's practice exam, and later today I'll post a brand-new CCNP SWITCH Video Boot Camp on this important topic!  Today's question is five questions in one.....

Which of the following is true of Uplinkfast?

A.  Used to protect the current root switch from being dethroned

B.  Applies to the native VLAN only

C.  Is recommended for use in the outer two layers of the Cisco 3-Layer Switching Model only

D.  Not recommended for use on root switches

E.  Is enabled on all VLANs on the switch or none at all -- this feature cannot be enabled on a per-VLAN basis.




Over 38,000 future and present CCNAs and CCNPs are in my Video Boot Camps on Udemy.

It's time for you to join us - and you can start my CCNP SWITCH course in minutes for just $44!


Join us today - click this banner or the link, and let's get started on your CCNP SWITCH pass!





And now... the answers!  From top to bottom ---

A is false. Uplinkfast doesn't really have anything to do with protecting the root switch.

B is false, and you'll see why in just a moment.

C is true.  You should use Uplinkfast in the distribution and core layers only - not on access-level switches.

D is true, as you can't enable Uplinkfast on a root switch.

E is true.  When you enable Uplinkfast on a switch, it's enabled for all VLANs on that switch -- not just the native VLAN.

See you later today with a new CCNP SWITCH Video Boot Camp!

And while you're here -- please check this out.  It's the best investment you can make in your CCNP SWITCH success, and it's about ten bucks!

... right after you take on this new practice exam!



1.   You just placed a port into VLAN 17.   Problem is, you haven't created VLAN 17 yet!     What's going to happen?

A.  You'll be prompted to create the VLAN.


B.  The port will enter err-disabled state.   You'll have to create the VLAN manually and then reopen the interface.

C.   The VLAN will be dynamically created for you.

D.   You'll be given an indication this is an illegal command.




2.  Speaking of that kind of thing, what's the full and exact command to place a port into VLAN 17, assuming you're at the port configuration level?



3.  You've configured OSPF on the following subinterface:


int s0.13 point-to-point
     ip address 172.1.1.1 255.255.255.0

By default, this interface will be seen as belonging to what type of OSPF network?

A.  NBMA

B.  Broadcast

C.  Point-to-Point

D.  Point-to-Multipoint

E.  There's not enough information here to answer the question.

We'll get to the answers right after this incredibly brief message!





I told you it was brief!  Now let's get to those answers....


1.  "C".   This is your lucky day!  The Cisco switch will dynamically create the VLAN for you.


2.  The full command to place a switch port into VLAN 17 is switchport access vlan 17.


3.  "C".   You might this the interface would be part of an OSPF NBMA network, and if it were a physical interface, you'd be right.    

When the interface is a point-to-point subinterface, though, it will default to the OSPF network point-to-point network type -- and that will have a serious impact on your adjacencies, as you'll see in Friday's brand-new CCNA and CCNP Video Boot Camp!

See you then!

Chris B.











Here's your CCNP ROUTE and TSHOOT Training Post for Thursday, November 7!
