Cisco Has Announced Three Additional CCNA Certifications!
But To Earn Them, You've Got To Be CCNA Certified, So Get Started Today!
Cisco has announced three brand-new CCNA-level Certifications:
CCNA Security
CCNA Voice
CCNA Wireless
Click those links to go to the new resource pages I've created for each new exam - I'll post practice questions, written tutorials, and video training on those pages in the weeks and months ahead.
There is a new CCNA Security tutorial on using SDM to configure one-step lockdown - the link is on the CCNA Security Resource page.
These new certifications are going to be a tremendous career boost to those who earn them.
Why? Just look at these statistics!
Security: Right now, 46% of companies included in the survey have a position dedicated to security - that's going to almost double over the next five years to 80%.
Voice: Currently, 40% of surveyed customers have a voice specialist. That number will rise to 69% in the next five years.
Wireless: While 33% of surveyed companies currently have a position dedicated to wireless, that value will double over the next five years to 66%.
(Stats were arrived at by Forrester Consulting during a study sponsored by Cisco. You can get a copy here.)
Those statistics tell a simple tale:
Network admins who have knowledge and certification in security, wireless, and voice will have a huge advantage over network admins who do not.
That's why Cisco is introducing these new certifications, and exactly why I'll be releasing Study Packages for all three of these specializations, beginning in September!
There's one detail you need to take care of now, though.
To earn any of these CCNA specialist certifications, you must earn your CCNA first, by either the one-exam (640-802) path or the two exam path (ICND 1 and 2).
This announcement by Cisco makes it more important than ever to be CCNA certified. Be ready to earn these new certifications by earning your CCNA now!
Just imagine how impressive your resume and reputation will be when you're CCNA certified and certified in security, voice, and wireless!
Personally, I'd hire you in a minute, and I've always been tough about who I hire. And if you already worked for me, you'd get the next promotion.
Get ready for these new certifications by starting on your CCNA now. Take five minutes to read this page - it's more important than ever.

Starting this September, I'll be releasing Study Packages for CCNA Security, CCNA Voice, and CCNA Wireless. While I'm working on those, you need to be working on your CCNA to take advantage of these vital new certifications.

Here are the answers to yesterday's questions!
CCNA Exam:
What command enables the dynamic mappings of DLCIs to IP addresses? Is this command used globally, at the interface level, or elsewhere?
Answer: That's the frame-relay inverse-arp command, and that should be enabled on the appropriate interface and/or subinterfaces. Inverse ARP is enabled by default on Cisco router serial interfaces.
CCNA Security Exam and CCNP / ISCW Exam Question:
What is RFC 3704 filtering, and why would we use it as part of a security plan?
Answer: IP Spoofing can be used against your network in several ways:
To inject a stream of malicious code and/or commands into your network
To trick legitimate network hosts into sending sensitive data to the attacker
As part of a reconnaissance attack, an attack that in itself may not be damaging, but is used to gather information for future, more destructive attacks.
RFC 3704 (an updated version of RFC 2827) recommends that packets from the following network ranges be prohibited from entering your network:
0.0.0.0 /8
10.0.0.0 /8 (RFC 1918 Class A private range)
127.0.0.0 /8 (loopback address range)
172.16.0.0 /12 (RFC 1918 Class B private range)
192.168.0.0 /16 (RFC 1918 Class C private range)
224.0.0.0 /4 (reserved for IP multicasts)
240.0.0.0 /4 (RFC 1918 Class E private range)
Blocking these address ranges for incoming traffic on your network's perimeter routers is sometimes called "2827 filtering" or "3704 filtering", referring to the original and updated RFCs that discuss this topic in a great deal of detail.
In the following configuration, what happens if you leave the subnets option out of the redistribution command?
R3(config)#router ospf 1
R3(config-router)#redistribute rip subnets
R3(config-router)#redistribute connected subnets
Answer: Subnets will not successfully be redistributed into OSPF.
What's the difference between Root Guard, BDPU Guard, and Loop Guard?
Answer: When a port is running Root Guard, no switch found off that port can become the root switch. When a superior BPDU is received on such a port, here's what you'll see:
00:26:46: %SPANTREE-2-ROOTGUARD_BLOCK: Root guard blocking port FastEthernet0/24 on VLAN0023.
If any BPDU comes in on a port that's running BPDU Guard, the port will be shut down and placed into error disabled state, shown on the switch as err-disabled.
Loop Guard prevents switching loops from forming due to unidirectional links. I'll have a fully-illustrated BCMSN exam tutorial on that subject on the website this upcoming week.
CCNP / ONT Exam:
Marking and classification often work hand-in-hand, but they're not quite the same thing. Define each term.
Answer: Classification identifies a certain type of traffic, while Marking is assigning a value to that class of traffic.
That's it for today! Enjoy your day, and I'll see you Sunday!
To your success,
