Question 3:  

Which of the following is true of an EIGRP loop-free route?



A.  AD > FD

B.  FD > AD

C.  AD = FD

D.  These two values do not matter as far as the absence of a loop in EIGRP routing.

Here are the answers!

1.  A, B.   EIGRP neighbors must agree on the metric weights and the AS number.  There is no area number in EIGRP, nor is there a "neighbor" command needed in EIGRP hub-and-spoke networks.



2.  B, C.  You'll find successor routes in both the EIGRP route and topology tables.



3.   B.  The Feasible Distance of an EIGRP route must be larger than that of the Advertised Distance for that route to be considered loop-free.

4.  B, C, D.   Autosummarization is on by default in EIGRP, and EIGRP supports VLSM.   

The backup routes, known as "feasible successors" in EIGRP-speak, are calculated in advance and kept in the EIGRP topology table.   

Wildcard masks are recommended with EIGRP configs, but they're not required.   

I'll see you Saturday with another new exam!

Here are the answers!

1.  (B).   You should use the ip ospf priority 0 command on the spoke interfaces to disqualify them from the DR/BDR election.



2.  The default OSPF cost of a Serial interface is 64.



3.   That's the default-information originate always command.


4.  (C).  The DROTHER will inform both the DR and BDR of the change.  The DR then floods news of that change to the rest of the routers on the segment. The BDR gets that info so it can keep its database totally up-to-date as quickly as possible in case it has to quickly step in for the DR.


I'll see you Wednesday with another practice exam! Keep grinding on that CCENT and CCNA deadline -- you can beat it!

Hi Bulldogs!


Time for a new CCNA and CCENT practice exam!


With a little over 30 days to go to the Sept. 30 CCNA deadline, there's a lot of anxiety out there.

Get rid of that anxiety with this free 4-minute video, tackle the practice exam, and then let's get back to work on beating that deadline!






Today's practice exam is a mixed bag, just like the real thing.  Let's get to work!


Question 1:  

Convert the hex value a7d to decimal.




Question 2:

Put these in order of their numeric value, from lowest to highest.


A.  STP port cost of a FastEthernet port

B.  Interval between Hello BPDUs transmissions by the root bridge

C.  STP's "Forward Delay" 

D.  STP's "Max Age"

E.  Default OSPF interface priority




Question 3:  

Two switches are connected via two crossover cables.  Of the four ports involved in those two connections, how many will STP block in order to prevent switching loops?






4.   Convert the binary string 00111101 to decimal.


The answers right after this!




35 days remain on the CCNA and CCENT exam game clock -- and I've got your back with this guarantee!

Here are the answers!

1.  The hex value of a7d breaks down to...

10 units of 256 = 2560

7 units of 16 = 112

13 units of 1 = 13

Add 'em up and you get 2685!


2.  From lowest to highest...

(E)  Default OSPF interface priority = 1

(B)  Seconds between Hello BPDUs = 2 

(C)  STP Forward Delay = 15

(A)  STP FastEthernet port cost = 19

(D)  STP Forward Delay = 20


3.  In that scenario, only one of the ports will be put into blocking mode.  The other three will be forwarding.


4.   The bits set to 1:  32, 16, 8, 4, 1.  Add 'em up and you get 61!


See you again Wednesday with another new exam, and anytime you're ready on YouTube and Udemy!

Hi Bulldogs!


I'm doing everything I can to help you get CCENT and CCNA certified before the Sept 30 deadline, and that includes a new practice exam right here on the Bulldog Blog every single day through Sept 30!


These practice exams are also tailor-made for those of you working on the new CCNA and CCENT exams, and I'll have new YouTube videos for those exams starting this very week!

By the way  -- if you haven't watched the latest CCNA video I've created for you, please take just 4 minutes to watch it right now.  After you're done, hit this new practice exam, and I"ll see you Monday with a new one right here on the Bulldog Blog!






Frame Relay hasn't gone anywhere - it's all over the 640-802 and 200-120 CCNA exams.  Let's sharpen our skills for success on either exam with this practice exam!


Question 1:  

What field in Cisco's version of HDLC enables multiprotocol support?


A.  ARP

B.  TYPE

C.  ACK

D.  REQUEST

E.  CONTROL



Question 2:  

Which of the following would result in show int serial0 giving you the following output?

"serial0 is up, line protocol is down"

A.  missing clockrate

B.  LMI mismatch

C.  loose cable

D.  all of the above


3.  In the following command, under what circumstances will CHAP be used?


ppp encapsulation pap chap


A.  If the PAP authentication attempt results in a failure.

B.  This is an illegal command, so CHAP will never come into play and the router will not accept the command.

C.  When the PAP authentication attempt results in no replies from the remote router.

D.  Once PAP results in a successful authentication, CHAP will be run as an authentication verification "double-check".



4.   I just ran a debug, and this is the entire output of that debug.  What debug is it?

20:47:52: Se1 CHAP: O CHALLENGE id 187 len 23 from "R1"
20:47:52: Se1 CHAP: I CHALLENGE id 186 len 23 from "R3"
20:47:52: Se1 CHAP: O RESPONSE id 186 len 23 from "R1"
20:47:52: Se1 CHAP: I RESPONSE id 187 len 23 from "R3"
20:47:53: Se1 CHAP: O SUCCESS id 187 len 4

20:47:53: Se1 CHAP: I SUCCESS id 186 len 4


The answers right after this important, time-sensitive message!




36 days remain on the CCNA and CCENT exam game clock -- and I've got your back with this guarantee!

Every single one of the 5,317 students in my CCNA Video Boot Camp get my fully-updated, all-new 200-120 CCNA Video Boot Camp in September - FREE!


Even if you don't get to take the current exam before Sept 30, or you don't pass, you'll have my all-new videos to prep you for the new exam...

Here are the answers!

1.  (B)   Cisco's version of HDLC added a TYPE field, which made multiprotocol support possible.    

2.  (A, B).  If the interface is up physically but the line protocol's down, there's a logical problem, and that could be a missing clockrate or a LMI mismatch. "C" is incorrect, because if the cable were loose, the "Serial0 is up" would actually say "Serial0 is down".


3.  (C).  The command ppp encapsulation pap chap means CHAP will be used if the PAP attempt times out due to a lack of replies from the other end of the link.  CHAP would NOT be used if PAP actively fails the remote router.


4.   That's the full output of debug ppp authentication.  You would also see that in the middle of the output of debug ppp negotiation, but you'd get a lot of other information, too!


Thanks for taking this practice exam!  I'll see you Monday with a new one, and anytime on YouTube and Udemy!

Here are the answers!

1.  (A).  Of those four, only switches allow us to break up a single broadcast domain into smaller ones.  

2.  (A).  An unknown unicast is a unicast frame whose source MAC address is not in the switch's MAC address table, and as a result of that, the frame is flooded.


3.  The source MAC address of incoming frames serves as the "password" for port security.


4.   Core, Distribution, Acccess.

A brand-new CCNA and CCNP practice exam has been added to this post -- along with my back-to-school $22 CCNA Security Special!

__________________________________

Hi Bulldogs!


Every CCENT and CCNA candidate in the world needs to see this video as soon as possible.   


If you're not working on either of those right now, please share it with someone who is -- or who's even thinking about it.  

Yes, it's that important!    Thanks for your help, and I'll see you later today with a new practice exam!

Chris B.











Let's get some work in with our hex, binary, and IPV6 conversions!

1.  Convert the hex value 4aF to decimal.


2.  Convert the binary string 00111101 to decimal.


3.  What is the shortest possible legal expression for this IP Version 6 address?

2222:1110:0000:0000:0000:3013:0000:0001


4.  Convert the decimal 45 to hex.


5.  What is the full 128-bit expression of this compressed IPv6 address?

3333:110:2220::5a:1

The answers right after this brief message - and you need to take advantage of this!

Earn one of today's most important certifications for just $22 with my CCNA Security Back-To-School special!

Over 1800 students have already taken advantage of this opportunity.   Join us right now -- for just $22!





And now -- da da DA da da daaaaa!  

The answers!

1.  With the hex value 4aF, you have:

4 units of 256 = 1024

10 units of 16 = 160

15 units of 1 = 15

Total =  1199.


2.   The binary string 00111101 has the 32, 16, 8, 4, and 1 bits set to "1".  Add those up and you have 61!


3.  Using both zero and leading zero compression on that address, and using our one instance of zero compression of the two consecutive blocks of zeroes for maximum compression, we get:

2222:1110::3013:0:1


4.  The decimal 45 converts to the hex value 2D (2 units of 16, 13 units of 1).


5.  To uncompress any IPv6 address, start by adding your leading zeroes back to any block where leading zero compression was used.  You know any block with less than four numbers but with at least one still there was compressed with leading zero compression.

That gives us...

3333:0110:2220::005a:0001

Then replace the set of colons (zero compression) with enough blocks to bring the address back to eight full blocks, and you're all set!

3333:0110:2220:0000:0000:0000:005a:0001

Done and done!

See you Thursday evening EST with more, and right now on YouTube and Udemy!





















Thursday, August 08, 2013



Hi Bulldogs!


Here's your free CCNA and CCENT practice exam for Thursday, August 8!


And thanks for watching my Udemy videos for over three MILLION minutes this summer!


If you're not there yet - wait no longer. Follow this link to my paid and free courses (including my famous $44 CCNA Video Boot Camp), and I'll see you there!

Chris Bryant's Video Boot Camps on Udemy

"I actually took a CCNA boot camp week long class and I was frazzled by mid week. I have actually had experience in my own production environment at my current job but still was overwhelmed at the amount of information. 

After starting this online boot camp class I was amazed at how easy it was to take it all in at my own pace. And the ability to keep reviewing the info whenever I needed to was a huge plus! Great training at an unbelievable low cost!"   -  Jason Palmer, a VERY happy CCNA Video Boot Camp student!
______________________________







Question 1:

In the following command, what does the first "2" represent?

int fast 0/0
    ipv6 ospf 2 area 2



A.  The interface identifier.


B.  The OSPF interface priority.

C.  The OSPF process number.

D.  The solicited-node multicast node number.

E.  None of the above.




Question 2:

Which of the following is true of the OSPFv3 RID?

A.  It's configured with the router-id command.


B.  It must be in IPv4 dotted decimal format, not in the format of an IPv6 address.


C.  If you have no IPv4 addresses on the router, you'll need to manually configure a RID.


D.  It must be in IPv6 address format; the OSPFv3 process will not accept an IPv4 address format for the RID.




Question 3:

With stateless DHCP and IPv6, which of the following values must still be supplied to the hosts via a DHCP Server?

A.  DNS Server

B.  Default gateway

C.  Lease duration

D.  The host's IPv6 address

Here are the answers!

1.  (C).  The first number is the process number, and the second is the area number.   (I know the second one is obvious. :)  )


2.  (A, B, C).  When it comes to the OSPFv3 RID, you can hardcode it with the router-id command, it has to be in IPv4 dotted decimal format, and if you don't have an IPv4 address on your router, you have to use the router-id command before you can continue with your configuration.


3.  (A).   DHCPv6 stateless autoconfiguration almost eliminates the need for a DHCP server, but not quite - the DNS server information still has to come from that server.
