A review for “Troubleshooting and Maintaining Cisco IP Networks (TSHOOT) Foundation Learning Guide: (CCNP TSHOOT 300-135)”

CCNP, Certifications, Cisco, Cisco Press

First and foremost I would like to thank my Professional friend Jamie Shoup for providing me the copy of this book. When it comes to preparations for Cisco certifications Cisco Press books are awesome. Cisco Press titles are written based on the blue print and topics covered for the exam.  The Cisco Press title “Troubleshooting and Maintaining Cisco IP Networks (TSHOOT) Foundation Learning Guide: (CCNP TSHOOT 300-135)” is crafted for the CCNP TSHOOT exam 300-135.

CCNP Tshoot

This title consists of 10 chapters covering following topics

  • Chapter 1 Troubleshooting Methods
  • Chapter 2 Structured Troubleshooting
  • Chapter 3 Network Maintenance Tasks and Best Practices
  • Chapter 4 Basic Switching and Routing Process and Effective IOS Troubleshooting Commands
  • Chapter 5 Using Specialized Maintenance and Troubleshooting Tools
  • Chapter 6 Troubleshooting Case Study: SECHNIK Networking
  • Chapter 7 Troubleshooting Case Study: TINC Garbage Disposal
  • Chapter 8 Troubleshooting Case Study: PILE Forensic Accounting
  • Chapter 9 Troubleshooting Case Study: Bank of POLONA
  • Chapter 10 Troubleshooting Case Study: RADULKO Transport

The author is quite smart in discussing the troubleshooting approaches in chapter 1, this really gives a good understanding of troubleshooting approach one could adopt in any given situation. Personally I liked the chapter that deals with the Network Maintenance best practices as the author discusses every aspect of troubleshooting including the most neglected part like documentation and policy.

The case study chapters are quite interesting and prepares a CCNP aspirer to think out of the box at times to troubleshoot the problems reported in day to day network operations and also now you have the liberty of downloading the typologies and diagrams from the Cisco press website for your own reference.

To conclude a good title, quite easy to understand what the author is trying to express, the only suggestion Cisco might consider is offering Virtual labs for the cases mentioned in this book or at least share the VIRL typologies so that one can have good hand on before appearing for the CCNP TSHOOT exam 300-135

Being CCIE is an ultimate thing in life?

CCIE, Certifications, Cisco certifications, Networking

Recently I received a message in LinkedIn, asking about CCIE, the question put forward to me was as follows

 ‪”I’m just curious about network technologies. There is a lot of hype about CCIE; it is said once you pass CCIE lab there are plethora of opportunities waiting for you. Some even speculate starting salary of 25k SAR in KSA. Is CCIE a global certification which is accepted worldwide even in North America?

‪Do you agree with aforementioned assertions? Please share some insights.”

ccie5

Many of the Networking or non-networking professionals have certain beliefs related to CCIE, some of them are

  • CCIE is an ultimate certificate.
  • Once one passed the  CCIE lab, he conquered the world.
  • Companies around the World will approach to him with amazing 3 digit offers.
  • A new horizon will open for him; he will be welcomed everywhere

Well all these things are wrong beliefs. Certainly it does adds value to one’s career, but at the same time he /she should justify the CCIE certificate he/she posses.

Recently trends are changing even college graduates with no networking experience started to prepare for CCIE labs and they are successful in passing the lab. Does this justify that; they have the same caliber of the experienced Network Engineer, certainly not. At one end this is a good sign, this shows how CCIE is valued in the professional world. But at the same time CCIE is losing its value due to huge increase in the number of CCIE s.

I believe experience and knowledge is what matters, not the certifications. Many people have a wrong perception towards CCIE; they think by passing the CCIE lab they can conquer the world. Well this is obsoletely wrong.

Wisdom and experience cannot be replaced by certifications, certifications does add value to those, who  already posses good experience in the field. Yes CCIE is one of most prestigious certification and accepted world wide, yes CCIE does offer a good remuneration provided that you are experienced and can justify your CCIE.

Virtual resources for Palo Alto Accredited Configuration Engineer (ACE) Exam preparations

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
Networking

When it comes to Palo Alto Accredited Configuration Engineer (ACE) Exam preparations, options are quite minimal in terms of virtual resources. As discussed in my previous post one can either relies on Palo Alto PA -200 firewall or their Palo Alto VM 100 firewall, you may need to contact your local Palo Alto team to get the trial access with license.

If you got hold of Palo Alto VM 100 firewall then preparing the lab scenario using Unified Networking Lab is quite easier.

You can find out more details about Unified Networking Lab by visiting their web site and I recommend you to download the unetllab from their website. Still it’s in beta version yet it is more powerful. You can simulate scenarios using many vendors’ virtual products.

Once you downloaded and installed the Unified Networking Lab do follow the instructions mentioned in this blog by Andrea the creator of Unified Networking Lab. This blog shows you how to copy the Palo Alto VM 100 firewall into Unified Networking Lab

In the next post I will show how to create the topology recommended by Palo Alto for   the Palo Alto Accredited Configuration Engineer (ACE) Exam.

Palo Alto should consider offering virtual labs for Palo Alto certification preparations

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
Cisco, F5

When it comes to preparations for any Certification exams, it is key to have an access to the appliance either in Physical or Virtual form. When it comes to Palo Alto certification preparations its quite challenging to find the virtual resources. Palo Alto recommends to practice their Firewall Installation, Configuration, and Management: Essentials I -Lab Manual on PA – 200 firewall which is a hardware appliance not a virtual appliance.

Palo Alto recommends the below shown topology for preparations of Palo Alto Accredited Configuration Engineer (ACE) Exam – PAN-OS 6.0

Well I believe the same topology can be created on the virtual environment especially when Palo Alto is marketing their virtual firewalls. Like F5 they can offer a trial license of 30 days purely for study purpose or certification purposes or like Cisco’s VIRL which can be bought at very nominal price. When it comes to preparations of much advance Palo Alto certifications like Palo Alto Networks Certified Network Security Engineer (PCNSE), one has to purely rely on either on Official Palo Alto training or hands on experience

It would be worth Palo Alto give a serious thought on coming out with a solution for their certification preparations especially when they are growing and trying to dominate the Next Generation Firewall world.

Two books one should consider while preparing for CCIE

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
CCIE, Cisco, Network, Networking

When it comes it comes to CCIE lab preparations most of us talk about the technical resources one should refer, hardly I see some one talks about the non-technical part of preparation. Well I am not trying to reinvent the wheel, yet would like to suggest two titles that will keep you motivated and help you to build a complete CCIE journey strategy.

There was great initiative by two gentlemen Dean Bahizad and Vivek Tiwari both of them are CCIE’s, they  understood the pain and come out with an amazing title called “Your CCIE Lab Success Strategy: The Non-Technical Guidebook

CCIE-Strategy

An amazing title, which serves as a personnel coach to some one who is preparing for the CCIE lab, they have crafted their journey in an interesting fashion and does offer lots of tips and strategies one could imagine of. So I certainly recommend to have this in your book self. This book offers a lot and its quite simple and a small book, which can be read in a week’s time.

Its been observed we give up the things even before starting the CCIE journey, we are afraid of failure, incompetency, no self confidence, no motivation to move forward, negativity, laziness and much more, in order to over come all these trials once could refer to Tony Robbins “ Awaken the giant with in “

Both these titles are quite helpful and will be your best friends for the journey of CCIE.

Does CCIE track selection needs counseling?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
CCIE, Cisco, Cisco certifications, Network

When it comes to choosing a CCIE track most of the CCIE aspirers are confused, everyday I encounter at least one CCIE aspirers approaching me for an advice. Some times I petty them but there are in need of guidance, so I morally try to support them and guide them to best of my ability.

CCIE

Why are most of them are confused in choosing CCIE tracks?

Its been observed that most of them are confused at the step 1 of CCIE, they struggle to choose a CCIE track for them, some of them try to meet instructor after instructor of different tracks to select the CCIE track, this makes them more confused. Even I have seem some people start with a CCIE track A for few months and then again they change their track to track B, this is not a good sign for some one who already started the journey of CCIE.

I believe most of them want to choose a CCIE track for different reasons like

  • Which CCIE track is in more demand?
  • Which CCIE track is easy to pass?
  • Which CCIE track offers me more remuneration?
  • Which CCIE track is easy to simulate?
  • Which CCIE track costs less?

So and so forth, well these are not the valid reasons to select a CCIE track. I strongly believe there should be strong desire and passion towards a particular track, which comes out when you ask the series of questions which mentioned in the article “ The Journey of CCIE – Series 1”. Yet some people may need some sort of Pre CCIE counseling in selecting a CCIE track and planning their journey.

Well as per my knowledge no one is offering such service, if some one wants to seek any guidance they can reach me out I can assist them in choosing their passions. Yes CCIE is a passion and can be only achieved when some one gives more than 100%. Please do feel free to reach me out, I will more than glad to help you.

What is Accredited Configuration Engineer (ACE) Exam – PAN-OS 6.0 Version exam ?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
configuration

Yesterday I passed the Palo Alto Accredited Configuration Engineer (ACE) Exam – PAN-OS 6.0 Version, the exam was quite easier provided you have hands on experience on Palo Alto firewall.

The Palo Alto Accredited Configuration Engineer (ACE) Exam – PAN-OS 6.0 Version is an entry-level exam of Palo Alto Certifications, which tests your knowledge of the core features and functions of Palo Alto Networks next-generation firewalls. The ACE exam is web-based and consists of 50 multiple-choice questions. The exam is not timed, and you can retake it as many times as necessary to earn a passing score.

Those who wants to be an Accredited Configuration Engineer (ACE) Exam – PAN-OS 6.0 Version, they just need to visit Palo Alto education website and get registered. Once done with registration, one can straight away attempt the Accredited Configuration Engineer (ACE) Exam provided he/she has the through knowledge of Palo Alto firewall. If not the best way to master ACE concepts is to register for Firewall Installation, Configuration, & Management (EDU-101 or EDU-201), EDU-101 is available at no cost as a self-paced online learning experience. EDU-201 is instructor-led with lab exercises and is offered through Palo Alto Network Authorized Training Centers (ATCs).

I took Firewall Installation, Configuration, & Management (EDU-101) self-paced online course which is about 6 hours long. The course is quite informative and the instructor has done an amazing job in explaining the concepts in simple language.

Certainly the Firewall Installation, Configuration, & Management (EDU-101) gives any one a good understanding of the concepts, but what about the hands on experience?  You can certainly use the Firewall Installation, Configuration, and Management: Essentials I -Lab Manual for this purpose provided you have an access to any Palo Alto firewall which is not under production. Palo Alto recommends PA -200 firewall for this lab, however if you don’t have physical appliances one can make use of Unified Networking Lab for the preparation of the Accredited Configuration Engineer (ACE) Exam. In the upcoming post I will try to shed some light on Unified Networking Lab and how you can make it as your source of preparation.

Can Cisco dominate the Next Generation Firewall domain?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
Cisco ASA, Cisco Firewall, Cisco security, Fortinet, Security

Recently Cisco announced threat-focused next-generation firewall (NGFW). Cisco is trying to integrate FirePOWER with Cisco ASA to provide the features of next-generation firewall (NGFW). Only time will say how successful Cisco will be capturing the Next Generation firewall market.

Currently we all know Cisco has a very little presence when it comes to Security products, leaders like Palo Alto, Check point , Juniper and to certain extent Fortinet are making their impact and presence in the firewall world.

datasheet-c78-733916_0

According to Cisco the ASA with FirePOWER Services features these comprehensive capabilities:

  • Site-to-site and remote access VPN and advanced clustering provide highly secure, high-performance access and high availability to help ensure business continuity.
  • Granular Application Visibility and Control (AVC) supports more than 3,000 application-layer and risk-based controls that can launch tailored intrusion prevention system (IPS) threat detection policies to optimize security effectiveness.
  • The industry-leading Cisco ASA with FirePOWER next-generation IPS (NGIPS) provides highly effective threat prevention and full contextual awareness of users, infrastructure, applications, and content to detect multivector threats and automate defense response.
  • Reputation- and category-based URL filtering offer comprehensive alerting and control over suspicious web traffic and enforce policies on hundreds of millions of URLs in more than 80 categories.
  • AMP provides industry-leading breach detection effectiveness, a low total cost of ownership, and superior protection value that helps you discover, understand, and stop malware and emerging threats missed by other security layers.

I do expect Cisco may have some impact on the market share, especially after acquiring Source Fire things may change the trends for Cisco. Cisco is trying to add the rich features and flavors of Source Fire products into its ASA firewall. Once I get an access to their Next Generation Firewall it will be much easier to comment on the services Cisco is offering and can be compared with their competitors.

The Journey of CCIE – In a nutshell

Yasir Irfan Yasir Irfan Profile: Yasir Irfan
CCIE, Cisco, Network

There is always an end to every journey, so this will be the last series I am going to write on my journey of CCIE, I will come back with articles in future that may hit the topics of CCIE Routing and Switching exam. But as a series this will be the last one.

in-a-Nutshell

Lets summarize all the ten series in this post, so that if some one wants to access all the previous series he/she may use the links mentioned here.

Series 1 – The power of questions was discussed and why it is important to ask empowering questions before starting a journey of CCIE.

Series 2 – The important of selecting the study material for the preparation of CCIE Lab and I highlighted some of the well-known resources one may opt for.

Series 3 – The well-known work books available and quite popular among CCIE aspirers.

Series 4 – In this article we reviewed Narbik R&S Workbook Bundle v5.0 and I gave my personel opinion about this bundle and why I opted this for my preparations for the lab.

Series 5 – We reviewed INE’s CCIE Routing and Switching version 5 workbooks and the great thing about the INE offers with this workbook and the virtual support they render for practicing their workbooks.

Series 6 – We discussed about the importance of having a Study plan for the journey of CCIE and what are things we need to consider while planning our preparations.

Series 7 – The importance of having a study partner and how it helped me to achieve my CCIE, I always recommend to have study partner.

Series 8 – The power one could have by challenging himself is awesome, so waiting for? Challenge yourself and achieve what you want.

Series 9 – The importance of following one’s passion is very to key to choose the track what you want to attempt.

Series 10 – How anyone can take control of their CCIE preparations by scheduling the lab, human brain supports remarkably when there is a target ahead. So schedule the lab feel the change.

I wish you all the best and I am pretty sure hard work never goes into vein, irrespective of the lab result the journey of CCIE it self teaches a lot.
