Tis more than time for a new CCENT and CCNA video - and today's video is one you CCNP Bulldogs should have a look at, too!


Apologies about my absence this past week. My parole officer was being a real pain.   

I KID!  I KID!

We'll start this vid with a very quick discussion of a situation that every computer certification candidate runs into sooner or later - one that you won't find discussed in any study guide (except mine!).

We'll follow that with an important lab -- so with no further ado, let's get to it right after you grab your copies of my ICND1 and ICND2 Study Guides!

I realize I've been strangely quiet lately.  

The silence ends today. 

 I am likely to remain strange, though.    : )

Here's your CCNA and CCENT Training Post for Sunday, Mar 9!


Let's hit today's practice exam on Telnet and SSH first!  


1.  A user just connected to your Cisco router via Telnet.  Assuming all default settings, what operational mode is that user in right now?



2.   What command will disable your the inactivity timer on a Cisco router's console port?



3.  It's a great idea to be able to telnet to your switch's management interface. By default, what interface is that?


4.  We'll wrap up with a multiple choice question.  Which of the following commands are required at minimum for a successful Telnet configuration?


A.  login

B.  priv level 15

C.  password

D.  logging synchronous


Answers coming right up --  right after you click these links! :)

Now let's hit those answers and hope they don't hit back! 

1.  By default, the user's in user exec mode.  If you want them to be able to enter privileged exec mode, you'll need to ... well, watch the video I post here Monday afternoon to see that in action on live Cisco routers!

2.  That's the exec-timeout 0 0 command.  Those are two zeroes, not two "O"s. :)


3.   Your Cisco switch management interface is VLAN1.


4.   A, C.   At the very least, you'll need the login and password commands configured on your VTY lines.  The other commands are helpful, but optional.

Thanks for tackling today's practice exam, and I'll see you Monday afternoon with a new CCNA / CCENT Video Boot Camp!

Here's your CCNP ROUTE and TSHOOT Training Post for Sunday, March 9!



As I was saying before Blogger rudely interruped me...

Today's Post has a new practice exam question followed by a VERY important CCNP ROUTE video.  Let's get to it!


Today's question:

Examine the following and tell me what numeric value, if any, will be used for the OSPF RID on this router.    Assume all interfaces are open and operating normally.

int loopback0
   ip address 10.1.1.1 255.255.255.0


int serial1
   ip address 172.12.1.1 255.255.0.0


int serial2  
   ip address 40.1.1.1 255.0.0.0


int fast0/0
    ip address 200.1.1.1 255.255.255.0

router ospf 1
    network 172.12.0.0 0.0.255.255
    network 40.0.0.0 0.255.255.255


We'll check out the answer and today's video right after this!


Our website is getting a makeover later this month  --

and we're celebrating now with this CCNP special, back in stock after last week's sellout!

Online access to every video in the course!

(US, APO, AE, UK, and Canada shipping only on this item.)

Get it all for just $199 -- right now!




Let's chat about that question:

If the router-id command is present in the OSPF config, the IP address specified with that command is the RID, no questions asked.

In this config, that command is not present, so the OSPF RID will be the highest IP address assigned to a loopback interface.

We have one loopback address here, so the OSPF RID is 10.1.1.1, even though that address is not OSPF-enabled.

It's vital to remember the address used for the RID does NOT have to be OSPF-enabled ( that is, named with the "network" command in the OSPF config.)

If there was no loopback, the highest IP address assigned to a physical interface would be the RID -- again, that interface would not have to be OSPF-enabled.

I can practically guarantee these rules will pop up in some fashion on your CCNP ROUTE and TSHOOT exams.   Easy points when you know the rules -- and here's a video to reinforce the RID concepts, and the entire lab's run on a live Cisco router. 

Enjoy!

Here's your CCNP SWITCH Training Post for Thursday, March 6!





Before we get started here, just a quick word -- for those of you asking how the new site's coming along, let me just say it's looking VERY good, and we expect to launch by the end of the month.

So if on occasion I haven't been here on the blog every day, the new website is to blame.  : )    It'll be worth it!


Right now, let's talk about ARP.

Do you give much thought to ARP at all?

Me either. It's a lot like DHCP, STP, etc., in that it works so well that we don't give it a lot of day-to-day thought.

Network intruders do, though, and that's why we have a little something called DAI -- Dynamic ARP Inspection.  That's what today's practice exam is all about, and there's a Video Boot Camp to boot.

Let's get started!


1.  The DAI process uses the same database used by another Cisco router function.  Which one?

A.  STP

B.  DHCP Snooping

C.  Username / password challenge

D.  PPP  (CHAP Only)

E.  None of the above.




2.   Dynamic ARP Inspection utilizes "trusted" and "untrusted" ports.  Which of the following happens when an ARP Request arrives on an untrusted port?


A.   The port goes into shutdown mode.


B.   If there is an entry for the ARP message in the database, the message is dropped.


C.    The port goes into err-disabled mode.


D.   The database is checked, and if there's an entry for that ARP message, the message goes on through.




3.    Which of the following matches Cisco's recommendations regarding DAI deployment?


A.  Trust ports connected to hosts


B.  Don't trust ports connected to hosts


C.  Ports connected to other switches should be configured as trusted


D.  All ports connected to other switches should be untrusted


Answers and today's video right after this!

Today's answers:

1.  "B".  Dynamic ARP Inspection and DHCP Snooping share a common database.  (As opposed to sharing a separate one, I suppose!)


2.  "D".   Don't fall for this one.  A port in untrusted mode does NOT shut down or disable itself in any way when an ARP message is received.   "Untrusted" just means the DAI database will be checked for a match.


3.  "B, C".  When you configure DAI to trust ports leading to switches and not trust ports leading to hosts, that means an ARP message will only be inspected once as it travels.   (DAI runs only on ingress ports!)


Now let's spend some time with this CCNP SWITCH Video Boot Camp on DAI, and I'll see you Friday, new website permitting! :)

Here's your CCNA and CCENT Training Post for Monday, Mar 3!


I've posted the latest CCNA and CCENT Video Boot Camps here for you, and there's a new practice exam ready for you, too.  

Let's get to it!











Now on to today's practice exam!


1.  When an EIGRP route is usable and is not currently being recalculated, what code do you expect to see next to that route in the topology table?

A.  D

B.  D EX

C.  E

D.  P

(Looks like an eye chart, doesn't it?)



2.   By default, how many secure MAC addresses does Port Security allow a port to have?

Bonus: If that answer is non-zero, tell me how the switch determines what address or addresses should be considered secure.


3.   Convert the hex value 9F to decimal.


Answers coming right up --  right after you click these links! :)

(Over 150 practice exam questions!)





Now let's hit those answers and hope they don't hit back! 

1.  (C).  Watch this one -- the Topology table will not have "D" or "D EX" next to any EIGRP routes.  That's in the Route table.  Routes that are ready for use are marked with "P" for Passive in the Topology table.



2.   Port security will allow a port one secure MAC address by default, and if you do not configure a static secure address, the next source address learned on that port will be considered the secure MAC address.


3.   The hex value 9F means we have 9 units of 16 and 15 units of 1.  144 + 15 = 159.

Here's your CCNP SWITCH Training Post for Monday, March 3!





Today's practice exam question is followed by a CCNP SWITCH Video Boot Camp you MUST see!

(Well, you don't have to.  But it would be smart!)



Today's Question:

Which of the following are Cisco switch defaults?

A.  Port Security runs in shutdown mode.

B.  The well-known MAC address for HSRP is 0000.0c07.acxx, with "xx" being the HSRP group number in hux.

C.  Port Security is set to allow no secure MAC addresses.

D.  HSRP interfaces are set with a priority of 100.

E.  The HSRP Hello time is 3 seconds.


We'll check the answer right after this!

(An even better deal - get all 3 CCNP Video Boot Camps for just $99!)



The answer to today's question: 

Every one of those is a Cisco switch default except "C".  By default, Port Security is set to allow one secure MAC source address.

Now, let's take a look at this Video Boot Camp for some important details on Cisco root switch elections, and I'll see you Tuesday with a new practice exam question and a new video to boot!
