Hi Bulldogs!

Here's another new CCNA practice exam for you -- and with just 61 days left until the Sept. 30 deadline, we can use all the practice we can get!  :)  


Let's hit it, and thanks for dropping by the Bulldog Blog today!



Question 1:

Which OSPF network types will result in a dash appearing in show ip ospf neighbor where you'd usually expect to see "DR" or "BDR"?


A.   Broadcast

B.   NBMA

C.   point-to-point

D.   None of them



Question 2:    

You have sequence number 10, 20, and 30 in an ACL. You remove line 20.  As a result, what will the number of line 30 change to?


A.  20

B.  25

C.  15

D.  It won't change.


Question 3:

Of "access-list" and "ip access-list", which allows you to use sequence numbers in order to edit the line order of an ACL?


A.  "access-list" only

B.  "ip access-list" only

C.   Both of these commands will allow it.


D.  Neither of these commands will allow that.




Question 4:

Give one practical reason for writing an explicit "deny any" as the last line of an ACL, as opposed to relying on the implicit "deny any".



Question 5:


You're editing the lines in an ACL.   What single command will remove line 30 from an existing ACL?



Answers right after this quick, important message!

OSPF Quick Quiz answers:

1.  (C).   An OSPF point-to-point network will not elect a DR or BDR.  We don't need either for a link that'll literally have two hosts to begin with.



2.   (D).  The existing sequence numbers in your ACL will not change.


3.  (B).  You do need to use "ip access-list" to edit a numbered ACL via the sequence numbers.


4.   You could write the explicit deny with log at the end in order to log the number of packets denied by that line.

5.  The simple line "no 30" will remove that line.  I'll post a free video on my YouTube CCNA Video Training Channel soon to show you how this works.

Be sure to check out the free practice exam in the next blog post!

And we're back --- again!  

My apologies for the lack of blog updates lately -- we've been running into some "issues" with our hosting friends that I believe have finally been resolved.   

So once again I'll be posting CCNA, CCENT, and CCNP links throughout the day, including a new practice exam.

See you later today!

Let's take a moment for a CCNA and CCNP Quick Quiz on IP Version 6, NAT, PAT, and more!

Question 1:

Which of the following do OSPFv2 and OSPFv3 have in common?  Choose all that apply.

A.   Sending of Hello packets for dynamic neighbor discovery.

B.   The SPF algorithm.

C.   The use of the router-id command to create the OSPF RID manually.

D.   The use of areas, the metric of "cost", and LSA exchange.

OSPF Quick Quiz answers:

1.  First, we gotta know that OSPFv2 is the good ol' OSPF we're come to know and love with our IPv4 configurations, and OSPFv2 is simply OSPF for IPv6.

Next, we have to know that while there are important differences between the two versions, none of them were listed in this question.  

Both versions use Hello packets, dynamically discover neighbors, use the SPF algorithm, offer the router-id command for manual setting of the RID, and both use areas, cost, and LSAs.



2.   The OSPFv2 reserved address 224.0.0.5 is represented in OSPFv2 by FF02::5, and the OSPFv2 reserved address 224.0.0.6 is represented by FF02::6.


3.  You can use the IP address on the outside interface with PAT, Port Address Translation, but you shouldn't do so with either version of NAT.


4.  The wildcard mask 255.255.255.255 is represented by the word "any".   With that wildcard mask, you literally have 32 "I don't care" bits.


5.  The hex value a4D breaks down to ...

10 units of 256  = 2560

4 units of 16 = 64

13 units of 1 = 13

... add 'em up and you have 2837!

See you tomorrow with five new CCNA and CCNP practice exam questions, and just maybe a new video or two!

Here's a brand-new CCNA and CCENT practice exam for you!

With 74 days to the Sept. 30 deadline, let's get in all the work we can!  :)

CCNA / CCENT Practice Exam Question 1:

Read this Cisco port security config written for interface fast 0/2 and identify the true statements.


switchport port-security

switchport port-security maximum 2

switchport port-security mac-address aaaa.aaaa.aaaa


A.  Port security will not work - this is an invalid configuration.


B.  The mac address "aaaa.aaaa.aaaa" will be considered secure.


C.  The next source MAC address seen by that switch port will be considered "sticky".


D.  The port will be shut down when any frames come in on that port, regardless of source MAC address.


Question 2:

Identify the defaults for Cisco port security.

A.  Mode


B.  Number of secure MAC addresses

C.  Enabled / disabled



Question 3:

A port has been shut down by Cisco port security. Which of the following is true of that port?

A.  Line protocol will be down.

B.  Physical status will be "administratively down".

C.  Will be "err-disabled".

D.  Will be "root-inconsistent".

And now -- the answers!

Question 1:

Correct answers are B and C.  With the max number of MAC addresses set to two and only one secure static address defined, that means the next dynamically learned address ("sticky") will also be considered secure.



Question 2:

The default Cisco port security mode is "shutdown", the default number of secure MAC addresses is one, and port security is disabled by default on all ports.


Question 3:

Correct answers are A and C.  The line protocol will be down, the physical interface will be down (not administratively down - that only happens when we shut the port manually), and the port will be error-disabled.


See you Friday with more!

I'll be posting new practice exam questions for the CCNA, CCENT, CCNA Security, and CCNP exams all day Friday!

Be sure to read the post below this one regarding the CCNA exam change - there's some vital information there!

Let's get started!

CCNA / CCENT Practice Exam Question 1:

When you run "show interface serial0", you're hoping to see "Serial0 is up, line protocol is down".

Each of the following situations will result in a different (and undesirable) readout for that command.   Tell me *exactly* what the output will be when the following situations arise:

A.  The cable is loose

B.  There's an encapsulation issue

C.  There's an LMI mismatch issue 

D.  The router interface has been left at its open/shut default

E.  The DCE is not supplying the clockrate


CCNA and CCENT Question 2 and 3:

Convert the binary string 00110111 to decimal.

Convert the hex value 4aF to decimal.



The answers are right after this quick, important message regarding the CCNA exam change!

And now -- the answers!

Question 1:

A.   If the cable is loose, you'll see "Serial0 is down, line protocol is down".


B, C, E:  All three of these situations will result in "Serial0 is up, line protocol is down".  The interface is fine physically, but logically there's a problem.

D.  Cisco router interfaces are shut by default, so you'll see "Serial0 is administratively down, line protocol is down". 


Questions 2 and 3:

The binary string 00110111 converts to the decimal 55.

The hex value 4aF represents 4 units of 256, 10 units of 16, and 15 units of 1.

1024 +  160  +  15   =   1199


See you later today with more questions and a video or two!

With the Sept. 30 CCNA and CCENT deadline approaching, I'm seeing the same understandable question in my email and in Twitter over and over....

"Do I still have time to get my CCNA before September 30?"

The short answer: Yes, you do.

Even better, though, is that while you're studying for the exam that expires on Sept. 30 (CCNA 640-802 and CCENT 640-822 expire that day)...

... you're ALSO studying for the new CCNA and CCENT exams!

And no, I'm not kidding!  Look at this list of huge exam topics...

Spanning Tree Protocol

Cisco Switching Fundamentals

Passwords

OSPF

Troubleshooting L2 and L3

Networking Models

Routing Fundamentals and Static Routing

EIGRP

WAN Protocols

... that's just a partial list of the topics that appear on both the "old" and "new" exams. 

So even if something happens that prevents you from even taking the current exams before Sept. 30, none of your current study time is wasted!

There is also a huge danger in delaying your studies due to the change, and I see this every time the CCNA exam changes.  Some students will just stop studying, thinking "I'll just wait for the deadline to pass and then concentrate on the new exams" -- and they waste MONTHS of their own career by waiting, and some of them never come back!

My advice to you -- keep studying for the current exams!

Here's another way to cover all your bases for the CCNA deadline:

... FREE.



And considering you pay only $44, with no additional or monthly charges of any kind for the videos, you're totally covered for the exam changes -- and you get my world-class, one-of-a-kind instruction.

Whether you choose my videos or someone else's, don't put your studies off - keep working, and you'll get the job done!
