Review for CCNP TSHOOT 642-832 Official Certification Guide

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

When it comes to preparation for Cisco CCNP TSHOOT 642-832 exam, you are not left with many choices, among the available the best sources are Cisco Press books.  Personally for me, my experience helped me to pass the Cisco CCNP TSHOOT 642-832 exam.  But for those who are new to industry they are dependent on study guides and CBT nuggets.

When it comes to study guides still Cisco Press titles are far superior to other publications.  The Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” follows the typical Cisco Press approach, each chapters begins with “Do I know this Already?” quiz and then followed by the subject. This approach is good as it lets you know to determine the knowledge level of the topic; it gives a brief idea to plan out the approach for each chapter. The title comprises of 15 chapters and the final chapter deals with the final preparations for the exam.

The good thing I like about this title is the way how author “Kevin Wallace” presented the known topics from different perspective. Yeah he was quite successful in engaging with his readers and presenting the troubleshooting techniques. The inclusion of many case studies enhanced the author’s presentation and he was quite successful in reaching out the mass. Especially for those who passed CCNP Route and Switch exam they find not much in this title, but they will learn the troubleshooting and maintenance techniques for complex networks. The troubleshooting scenarios and methodology grabbed my attention and I like the way troubleshooting tickets were presented.

I have few suggestion to Cisco Press is to include the pdf version of the title with the CD. The CD also came with the Boson Exam Environment Engine (BEE), it was a huge disappointment for me as the practice exam failed to contain the simulated scenarios. The BEE contained only multiple choices, single choice, drag and drop style questions.

Overall the Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” is a good source for anyone who is preparing for Cisco CCNP TSHOO 642-832 exams and a helpful guide for those who wants to master troubleshooting.

Cisco planning to acquire BNI Video

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Last week Cisco Systems announced its intention to acquire BNI Video, headquartered in Boxborough, Mass.,. BNI Videos are involved in supping video products to service providers that offer video back-office and content delivery network (CDN) analytic capabilities. This announcement is quite evident about Cisco intention to expand its capabilities in its Videoscape TV platform. The main aim of videoscape is to allow service providers to deliver compelling video experiences to any device over any Internet Protocol (IP) network.

“Cisco is committed to working with our service provider customers to deliver next-generation IP-based video experiences across devices,” said Marthin De Beer, senior vice president and general manager of Cisco’s Emerging Business Group. “Service providers globally are embracing our Videoscape vision, and today with the acquisition of BNI Video, we are augmenting our Videoscape platform and giving customers a clear migration path to Videoscape.”

“As a founding investor in BNI Video, Comcast Ventures recognized the potential for this technology to play a critical role in advancing video experiences for Comcast’s customers,” said Tony Werner, chief technology officer, Comcast. “With the combined expertise in IP video systems, Cisco and BNI Video offer service providers a compelling software and infrastructure platform to efficiently deliver video content to multiple devices.”

“Time Warner Cable invested early in BNI Video, as it brought a unique software platform to market that addresses the back-office complexities of delivering TV Everywhere services,” said Mike LaJoie, chief technology officer, Time Warner Cable. “Combining forces with Cisco presents an opportunity to take video service providers to the next level with Internet video, helping to manage networks more efficiently to deliver advanced TV entertainment experiences to consumers.”

Upon the close of the acquisition, BNI Video employees will be integrated into Cisco’s Service Provider Video Technology Group. Under the terms of the agreement, Cisco will pay approximately $99 million in cash and retention-based incentives in exchange for all shares of BNI Video. The acquisition is subject to various standard closing conditions and is expected to be complete in the second quarter of Cisco’s fiscal year 2012.

How to pass Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam? – Series 2

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

For those who are new to Cisco Domain, I strongly recommend them to read the Cisco Press title which for sure will help them to understand the approach they must apply, especially whenever they are troubleshooting any problem in a complex Cisco Network.  Also I strongly suggest building a GNS3 topology based on solutions provided in the Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” and you can also make use of Cisco Press title “CCNP TSHOOT Lab Manual“.

The best thing I like about this lab manual is all configuration files can be downloaded from Cisco Press website. Practice makes man perfect; by troubleshooting various scenarios, which you can build using the above mentioned resource can help you in mastering CCNP TSHOOT topics and can, learn the various approach adapted to trouble shoot more complex Cisco networks. Of course nothing can replace the practical experience but when you simply don’t have that privilege, you can make use of GNS3.

I am hopeful by simply passing Route and Switch exam; you will gain enough confidence and expertise to pass the Cisco TSHOOT exam. Better luck for those who are appearing for the TSHOOT exam, make sure you watch THSOOT Strategies on YouTube by Kevin Wallace which does give you an idea how the real exams look like and do practice the CCNP TSHOOT demo exam available at Cisco web site.

How to pass Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam? – Series 1

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Dear CCNP Certification aspires, the moment you pass the Cisco CCNP Route (642-902) and CCNP Switch (642-813) exams consider yourself you are ready for the Cisco CCNP TSHOOT (642-832) exam. The Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam basically aims at testing you knowledge and skills to plan and perform regular maintenance of complex Enterprise Switched and routed networks  along with testing your skills well known network maintenance models like Cisco Lifecycle Services, FACPS, ITIL and TMN.

The secret behind passing the Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam depends on how good you are at troubleshooting, your experience on maintain and managing complex networks, and of course the courage to challenge yourself by focusing and thinking logically on tickets appear on the real TSHOOT exam.

Since I passed the Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exams I was mentally ready to take the challenge of Cisco TSHOOT exam, but my busy schedule was preventing me. Finally I set the date when should I appear for the Cisco TSHOOT exam and I came out passing the exam. Believe me, it was the easiest Cisco Certification exam I appeared till date in my life.

When it comes to exam preparation I got hold of Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” and checked the latest exam topology published by Cisco Systems. Yes Cisco System does reveal the topology which appears on the real exam, which itself will ease your burden of preparations. Since I possess over a decade of experience on maintaining and managing Complex Cisco Networks I didn’t find myself reading the Cisco Press title from cover to cover. Just read first two chapters for the sake of curiosity. But prepared the GNS3 topology based on the exam topology published by Cisco Systems and practiced few scenarios. I will cover the approach need to be adopted by CCNP aspirers who are pretty new to Cisco Networks in the upcoming post.

Cisco Power Calculator an amazing tool.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Currently we are working on the power calculation and the heat dissipation by the Data Center Switches. Rather looking at each individual catalog, I figured out  Cisco Systems are offering a dynamic tool which helps to calculate the total power required, typical output power, total heal dissipation.

The tool is known as Cisco Power Calculator (CCO login required):/

This utility asks you the type of switch you are using, what kinds of modules you are using, type of supervisor engine etc. After providing all the details the utility provided you a in depth report and you can download the same in an excel sheet or in pdf format. I am attaching the sample report which I calculated for one of our Cisco Catalyst 6513 Switch.powercalc_catalyst_6500_09-27-2011

Review for Cisco CCNP Route 642-902 CBT Nuggets Series

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

In one my articles “How to pass CCNP Route Exam?” I talked about the resources required to peruse CCNP route 642-902. One of the very useful resources is Cisco CCNP Route 642-902 CBT Nuggets Series. I though why not write a review for this product.

As we all know CBT nuggets happens to provide world class training for IT Certifications. They hire best trainers in the industry and deliver excellent training materials for aspiring IT Professionals. When it comes to Cisco Certifications Jeremy Cioara is my favorite. Why? You will discover soon.

He has authored various Cisco books some of them are CCNP Voice Official Certification Guide, Cisco IP Telephony (CIPT), CCNA Exam prep and CCNA Practice questions.  Most important contribution to Cisco Certifications he has made is his affiliation with CBT nuggets to produce world class Cisco training stuff staring from CCNA, CCNP, to CCIE.

When it come the Cisco CCNP Route 642-902 CBT Nuggets Series it’s an awesome series with 28 videos covering all the topics required to pass the CCNP Route exam. What make this series outstanding are the speaking skills of Jeremy Cioara and the in-depth technical knowledge he possess. Jeremy connects with audience as if he is talking to you directly; the way he teaches any concept is amazing. Especially his personalized stories and tips he shares make this series outstanding.

I don’t want to emphasize on the contents of this series as its covers A to Z of CCNP route exam, one thing I would like to highlight about this series is the inclusion of GNS 3 labs , it does gives hands on experience for the CCNP route exam starting from EIGRP to OSPF, BGP and IPv6.  One more key element of this series is inclusion of MP3 files which are quite handy while you are driving or travelling, again it’s the quality of great speaker who manages you to learn the concept even without watching them.

A valuable asset for CCNP aspirer, I strongly recommend all CCNP aspirers to buy this series.

What is Universal Power over Ethernet (UPOE)?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

When it comes delivering power to Cisco Access Points and Cisco IP Phones we all know about the IEEE 802.3af standard which defines standard Power over Ethernet (PoE).  But what is Cisco Universal Power over Ethernet (UPOE)? This is new term for most of us.

It’s a new innovation from Cisco Systems which happens to the industry’s first 60-watt Power over Ethernet technology which Cisco called Universal Power over Ethernet (UPOE).

Cisco Universal Power over Ethernet (UPOE) can offer twice the power per port of products from competing switch vendors – providing both power and network access to a greater range of devices through a single standard Ethernet cable. This can surely help to lower the total cost of IT operations. By using Cisco’s new UPOE line card and UPOE splitter, any device requiring up to 60-watt power can now be powered by Cisco’s Catalyst 4500E Switches. This includes Cisco IP phones, personal telepresence systems, compact switches and Cisco wireless access points.

[kml_flashembed movie="" width="425" height="350" wmode="transparent" /]

Currently Cisco is working with IEEE and third-party device manufacturers to standardize UPOE in next-generation, network-enabled devices. Which for sure may lead to new PoE standard from IEEE?

Currently  Samsung zero client desktop virtualization devices and BT IP turrets have integrated Cisco UPOE technology into their devices to allow customers the immediate advantage of using their existing Cisco network to power these solutions. This is good sign for this emerging technology. Cisco also tested many devices using UPOE technology like Oracle Sun ray clients.

Currently the Cisco Universal Power over Ethernet is available with a new line card on the Cisco Catalyst 4500E switch. The Single Cisco Catalyst Switch 4500E chassis can support up to 120 UPOE ports. The OPOE is utilizes the existing UTP Cabling standard Cat 5e or higher and RJ 45 connectors for deployment. This helps the customers to make use of their existing cabling infrastructure.

Review for CCNP ROUTE 642-902 Official Certification Guide by Wendell Odom

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

In my previous article, we over looked how to pass the CCNP Route 642-902 exam? Also I mentioned the resources required to pass the CCNP Route 642-902 exam. First and foremost the most valuable resource available is the title from Cisco Press called “CCNP ROUTE 642-902 Official Certification Guide by Wendell Odom“.

I thought let me review this title for the benefit of Cisco Certification aspires. No doubt the CCNP ROUTE 642-902 Official Certification Guide is an excellent title with lot of info available in depth. As promised by Cisco Press this title is covers all the topics of Cisco CCNP Route 642-902 exam. This title too follows the typical Cisco Press Style; each chapter begins with “Do I know this Already? Quiz? Which is good to assess your knowledge and accordingly you can prepare for the exam. The best thing I personally liked about this title is the author started by reviewing EIGRP from CCNA perspective.

When I first Wendell Odom’s ICND 1 and 2, I was zapped with his technical writing skills and the way he presented the topics were simply awesome. I was expecting similar interesting wring from Wendell in   title CCNP ROUTE 642-902 Official Certification Guide, but rather it was bit boring and lengthy. There are few typos as well in this title. It would have been a great title if the concepts were explained in short and concise.

However I think this title has a lot of great information in it which is sufficient to pass the Cisco CCNP Route 642-902 Exam. Wendell Odom does a great job of explaining things in detail. I just wish it was an error free title especially when it comes from Cisco Press.
