Passed ITIL v3 Foundation exam

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

 

Yesterday I passed ITILv3 Foundation exam, these days I am on my vacation in Bangalore. Since arrived I was thinking of ITILv3. I started contacting ITILv3 training centers and figured out VYOM labs is the best training center in this part of the World. Initially the training dates in Bangalore were conflicting with my brother’s wedding date, so I started looking other leaders in ITIL training in Bangalore.

 

Somehow things didn’t work well for me in Bangalore for training; again I approached VYOM labs for any training schedule in and around Bangalore on 26 & 27th of March. Pune was the only destination where ITIL v3 foundation training was conducted. I decided to attend the Pune ITIL v3 training offered by VYOM labs. It was worth attending the training. The instructor Ms. Beena Dhage an ITIL expert conducted the training in excellent way. I would strongly recommend to attend her training sessions if you are planning for ITIL v3 foundation. Two days of rigorous fun filled training and little practice can help you achieve IITL v3 foundation. I did also enjoy the company of my fellow trainees who were very supportive and most of them too pass their ITILv3 exam at first attempt. Congrats to them.

I hope to start next step in ITIL by preparing for life cycle modules ” Service Strategy or Service Transition” may be this time I will go for an online training with VYOM labs as they are offering both foundation and Intermediate trainings.

You can contact VYOM labs for more information on training info@vyomlabs.com

SonicWall has introduced Deep Packet Inspection for SSL (DPI-SSL) traffic as part of its latest SonicOS release.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

SonicWall adds Deep Packet Inspection for SSL traffic in its latest SonicOS 5.6 release. Whenever you upgrade your SonicWall firewall with the latest SonicOS 5.6 OS it will help counter the growing risk from encrypted threats, and from legitimate encrypted applications which may bypass content filtering and leak valuable information or expose networks to attacks from malware.

The OS upgrade includes DPI seamlessly applied to SSL traffic, and can inspect inside all SSL sessions across all ports, independently of the protocol, resulting in both encrypted and decrypted data being scanned, monitored and protected.. It also includes SonicWall’s Re-Assembly Free Deep Packet Inspection (RFDPI) engine.

“Encryption is obviously an essential tool in security.  Yet encryption is now being used as a tool to defeat security,” said Patrick Sweeney, vice president, Product Management. “With SonicWALL’s DPI-SSL inspection capabilities, companies can ensure that security tools are working for them, not against them. Companies are put back in control of the data that leaves their network while controlling what web sites users’ access.”

Cisco splits from HP

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

 

Cisco will not renew the reseller contract with HP which is due to end by April 2010. Which means HP will no longer be a Cisco Certified Channel Partner or Global Service Alliance Partner. The increased competition between two giants in the Data Center Sector is the main reason for this split, Keith Goodwin, Senior Vice President of Cisco’s Worldwide Partner Organization said on a webcast.

Keith Goodwin, senior vice president of Cisco’s worldwide partner organization said in a statement: “Being a Cisco Certified Channel Partner has numerous benefits including access to proprietary information (such as product roadmaps) and partner profitability initiatives. Given the evolution of our relationship it simply no longer makes sense to provide these benefits to HP.”

According to figures from Dell’Oro Group Cisco had more than two-third of the Ethernet Market Share in last third quarter, whereas HP and 3Com were at second and third place. HP is no shaping up to be not just a competitor to Cisco but also it might be Cisco’s biggest rival. With acquisition of 3Com, HP has a fair line up of both routing and switching product.

Review for CCNP SWITCH 642-813 Official Certification Guide

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

 

I am always a great fan of David Hucaby; he comes up with pretty good titles, which can be easily used for achieving Cisco Certifications by self-study. His latest addition to the world of Cisco Certification is CCNP SWITCH 642-813 Official Certification Guide.  Thanks to Cisco Press and David to release this title so soon.

 

Thanks to Cisco Press and Jamie in especial for making this happen. I don’t believe that I have a CCNP SWITCH 642-813 title with me. As we all know Cisco came up with a new version of CCNP Certification which requires only three exams to pass compared to four in the prevision version of CCNP.

 

 

The current CCNP SWITCH 642-813 book is much lighter compared to the CCNP Switch 642-812 book.  It’s divided into 6 parts. I liked the way topics are distributed. This book is written in an easy way it covers all the exam topics and also provides some good troubleshooting steps especially I liked the VTP troubleshooting part.

A chapter dealing with Securing Switch access is amazing I liked the best practices used for securing Switches. The Author David Hucaby did a commendable job. The CCNP Switch 642-812 title come with 100 practice questions for the CCNP 642-813 exam developed by Cisco Press and delivered by Boson. The CCNP SWITCH 642-813 title is up to date and most of the info referred deals with the latest IOS versions.

 

 

Overall this entire book is an excellent source for preparing for Cisco CCNP 642-813 exams, my advice is to buy this book along with CCNP Routing and Switching Quick Reference  book. With these two, you should have everything you need! Best of luck to you all CCNP Certification aspirers.
