Want to become a CCNP? There are six steps to help you becoming a CCNP (Cisco Certified Network Professional) and increasing your chances of capturing the right job and joining network support personnel.

1. Compare professional certification options on the Cisco website. Find out that the CCNP is just one of many professional certifications available. Choose the “Participating in the Program” link to find approved Cisco training facilities and schools in your area whether you’ve obtained the CCNA elsewhere or prefer to change your current training facility or school.
2. Finish curriculum requirements and successfully pass the CCNA exam (and possibly obtain the recommended CCENT training/exam beforehand). Certify your capabilities to install, configure, as well as troubleshoot LANs or WANs and become a CCNP.
3. Discover that many traditional colleges offer Cisco networking training; however, some don’t have higher level certification courses available. Unearth Cisco-approved training facilities and online courses that typically offer higher level Cisco networking certification training. Evaluate cost, convenience and courses.
4. Realize that grasping and memorizing CCNP material and coursework is hard work, and the pace and intensity rivals that of the CCNA training. Set up for taking in new complex information as well as taking on new costs and testing.
5. Demonstrate new knowledge and skills acquired in CCNP training for managing routers/switches plus integrated voice, wireless as well as security network applications to become a CCNP. Consume information from the “Building Cisco Multilayer Switched Networks (BCMSN),” “Building Scalable Cisco Internetworks (BSCI),” “Implementing Secure Converged Wide Area Networks (ISCW)” and “Optimizing Converged Cisco Networks (ONT)” training courses to become a CCNP. Make sure programs are taught by certified instructors and cover the Cisco-approved CCNP curriculum.
6. Double check course details before signing up for a Cisco certification program and investigate the school or training facility to make sure it is Cisco approved. Become a CCNP once you’ve successfully mastered the curriculum and completed the certification tests. Pass the combination of the 642-901 BSCI, 642-812 BCMSN, 642-825 ISCW and 642-845 ONT required exams; or pass the combination of the 642-892 Composite, 642-825 ISCW and 642-845 ONT required exams.

David: “My brother is about to face the 642-901. He felt kind of confy two weeks ago, but now he′ve heard about so many people failing, that he′ll be preparing a litte more before diving in.

To prepare he took the Boson training last week with the new courseware and thought it was preety good, however he is still trying to get some decent test simulation software(Boson′s still 801 -oriented and the router simulator simply doesn′t do a good job). He also got the new BSCI book which seems superior to the previous one, at least in the chapters that he reviewed. Anyone knows anything about an updated software? All other comments on the 642-901 exam are welcome too.”

Exam Description: The Building Scalable Cisco Internetworks (BSCI 642-901) is a qualifying exam for the Cisco Certified Network Professional CCNP?, Cisco Certified Design Professional CCDP?, and Cisco Certified Internetwork Professional CCIP? certifications. The BSCI 642-901 exam will certify that the successful candidate has important knowledge and skills necessary to use advanced IP addressing and routing in implementing scalability for Cisco ISR routers connected to LANs and WANs. The exam covers topics on Advanced IP Addressing, Routing Principles, Multicast Routing, IPv6, Manipulating Routing Updates, Configuring basic BGP, Configuring EIGRP, OSPF, and IS-IS.

With the new and updated exams its hard to recommend stuff — the “old” stuff may have been good, but no idea about the “updated stuff.”

For the Old CCNP I used the Cisco Press Flash Cards and Practice Exams — and thought success on the practice questions did indicate possible future success on the real exams. Plus I like the “reference sheets” that were PDF files on the CD (which sound like they may be available separately now from Cisco Press). Not sure if the updated Flash Cards/Practice Exams are available.

Boson does the test engine for the Flash Cards and for the Practice Exams that come with the Cisco Press books. In the past they had different “exam sets” you could buy if you needed more practice (or another evaluation of real exam readiness).

Serum is a complex mix of albumins, growth factors and growth inhibitors and is probably one of the most important components of cell culture medium. The most commonly used serum is fetal bovine serum. Other types of serum are available including newborn calf serum and horse serum. The quality, type and concentration of serum can all affect the growth of cells and it is therefore important to screen batches of serum for their ability to support the growth of cells(take especial care of 96 well plate). In addition there are other tests that may be used to aid the selection of a batch of serum including cloning efficiency, plating efficiency and the preservation of cell characteristics.

Fetal bovine serum (FBS) has been used to prepare a number of biological and has an excellent record of safety. The recognition of Bovine spongiform encepalopathy (BSE) in 1986 and it’s subsequent spread into continental Europe along side the announcement of the probable link between BSE and a new variant of Creutzfeldt Jacob disease in Humans, stimulated an increased concern about safe sourcing of all bovine materials. In 1993 the Food and Drug Administration (FDA) “recommended against the use of bovine derived materials from cattle which have resided in, or originated from countries where BSE has been diagnosed. The current (European Union) EU guidelines on viral safety focus on sourcing, testing and paying particular attention to the potential risk of cross contamination during slaughtering or collection of the starting tissue. As far as BSE is concerned, the EU guidelines on minimizing the risk of BSE transmission via medicinal products, CPMP/BWP/877/96, recommends the main measures to be implemented in order to establish the safety of bovine material versus the BSE risk. Again, similarly the focus is on geographical origin, the age of the animals, the breeding and slaughtering conditions, the tissue to be used and the conditions of it’s processing.

The use of FBS in production processes of medicinal products is acceptable provided good documentation on sourcing, age of the animals and testing for the absence of adventitious agents is submitted. All responsible suppliers of FBS for bio-pharmaceutical applications will provide such documentation.

Recent regulatory requirements in Europe stress the importance of justifying the use of material of bovine, caprine or ovine origin in the production of pharmaceutical products. Thus, although FBS has been used for many years in the production process of many medicinal products such as viral vaccines , recombinant DNA products and ELISA Plate, at present there is a justified trend to remove all material of animal origin from manufacturing processes. Sigma-Aldrich has recognized this growing trend and works closely with customers to optimize animal free media formulations to meet each customer’s cell culture requirements.

Similarly the FDA has similar guidelines when accepting regulatory submissions. The FDA regulates all medicinal products for Human use, such as therapeutics, vaccines ,diagnostics and Cell Culture Plates, and, usually, the United States Department Agriculture (USDA) are not involved.

This article provides helpful information for you to prepare for Cisco exam 350-001, the CCIE Written exam. The CCIE (Cisco Certified Internetwork Expert) certification has historically been the most valued in the area of networking. There are two steps to achieve this valued certification:

• A 100 question written test, which this Cramsession will help to prepare you for
• And an intense lab exam, which will test the limits of your technical knowledge

I’ve compiled a list of study suggestions for 350-001 that you might find useful:

• Print out a copy of the exam 350-001 blueprint from the Cisco website. Use this as the basis of your notes, and don’t consider yourself ready for the exam until you are completely comfortable with ALL the topics on the list. The blueprint changes occasionally, but the current version can be found at: Written Exam Blueprint v3.0
• Buy a few books. This seems simple enough, but I’ve found there are two types of books lists for the CCIE - those for the lab and those for the written. They’re not the same. For our purposes here, there are two things we want to accomplish with our reading: to quickly get the written out of the way to start the long road to the lab; and to try as much as possible to conserve money and time by finding and reading materials that are applicable to both.
• Download sample exams. There are several available, but regardless of which vendor’s questions you choose, take advantage of a significant pool of questions, and select products by different authors. The subject matter for this exam is broad, and you want a good selection of material to study from.

Want to start getting into routers etc so looking at doing some cisco stuff? Think you need to start on the CCNA? but dont really know where or know of any real books that can teach you this from scratch? Here is a guideline for the Cisco newbies to start on the CCNA.

Q: Looking at doing some cisco stuff?

A: Cisco’s Career Certifications & Paths information can be found here.
Cisco also has a CCNA Prep Center — it might impress you, or it might scare you away — but worth a look to get an idea of what Cisco makes available.

Only one comment on the prepCenter. When watching the flash, dont take their word when they say that linux is an operating system. One who says that linux is an OS, states that his knowledge of operating systems converging to zero (especially linux based).

Q: Don’t really know where or know of any real books that can teach you this from scratch.

A: The books you’ll hear the most about around here are:
Sybex - Cisco Certified Network Associate Study Guide — by Todd Lammle. Should be on the 5th edition. Great for learning subnetting. Missing some info, but there are one or two new update chapters available for download.
Cisco Press - The CCNA 640-802 books by Wendell Odom. Probably the CCNA Official Exam Certification Library.
You can check out all the Cisco Press Books (and the link to the simulator) at the Cisco Press Web site.
Hands-on practice is important…. but you can get by with the simulator for the CCNA.

Q: Are the exams expensive?

A: The CCNA 640-802 exam is $125.
There is also the 2 exam option (INTRO and ICND). There should be link at the CCNP Prep Center that explains it. I think those are $100 each.

Large numbers of cell lines look identical. Cell lines with very different origins and biological characteristics typically cannot be separated on grounds of morphology or culture characteristics. Infection or contamination of a cell line with an adventitious virus or mycoplasma may significantly change the characteristics of the cells but again such contamination will be inapparent. Cell lines will also change with time in culture(even in glass bottom dishes/elisa plate), and to add to all these natural hazards it is all too easy to mis-label or cross-contaminate different cell lines in a busy cell culture laboratory.

The opportunities for inadvertently introducing error into a cell line are limitless and ever present. It is in the nature of the science that, once introduced, an error will be propagated, compounded, consolidated and disseminated.

The integrity and biological characteristics of a cell line have to be actively maintained by a well-organized system of “husbandry” based on systematic cell banking supported by testing regimens in a structured quality assured environment. Such a controlled environment will only prevail in a dedicated professionally organized cell culture laboratory or cell bank. A small research laboratory with a high throughput of short-term research students, a minimum of permanent laboratory staff and no formal quality management program will find it difficult to maintain its cell lines unchanged over many years.

For all these reasons it is strongly recommended that new cell lines should only be acquired from a specialist, reputable culture collection such as ECACC. Moreover, if a laboratory believes it already has a certain cell line in its liquid nitrogen store, the identity and purity of such a cell line should be questioned in the absence of a well-recorded culture history and recent test data. If there is a doubt, it is straightforward and cost effective to replace such cell stocks with authenticated material from a Culture Collection.

When a Cell Culture Collection “accessions” a new cell line it will characterize the cell line using techniques such as isoenzyme analysis and DNA profiling so that the identity of the cell line can subsequently be verified. The Collection will then establish a hierarchy of Master and Working cell banks, cryopreserved in liquid nitrogen, that are demonstrated free from microbial contamination including mycoplasma. Customers are supplied from these authenticated Working Cell Banks (WCB). Replacement WCB’s are manufactured from the original Master Cell Bank (MCB) and the new WCB will again be fully tested.

ECACC supplies its cell lines together with advice on how to maintain the line. A Technical Support team will subsequently assist with any difficulties and can often provide additional technical information about the cell line. Culture Collections exist to ensure that animal cell research is conducted using standardized, authenticated material that ensures the work can be reproduced(such as Glass Bottom Cell Culture Dishes, 96 well plate etc). An authenticated cell line of known provenance is the very “bed rock” of any cell based project.
