* What kinds of certifications should I consider for a PC Specialist career?

As a PC Specialist, people will rely on your specialized computer training and skills to keep the office running smoothly. You must have the following certifications:

• PC Specialist Certificate
• Microsoft Certified Systems Engineer
• Microsoft Certified Professional

* What kinds of certifications should I consider for a Software Engineer career?

The software engineer designs and develops systems to control and automate manufacturing, business, or management processes. To obtain a position as a Software Engineer, you must have:

• A four-year degree in a computer-related discipline is required for most software engineering positions.

• Certification in various software applications is suggested.

• Training programs are available at community colleges, vocational schools, technical institutes and in the Armed Forces.

Earning and maintaining computer certification is a good way for software engineers to keep their skills up to date. In addition to Microsoft, Novell, Cisco and other high-tech companies, the Institute of Electrical and Electronics Engineers (IEEE) Computer Society offers relevant computer certifications.

* What kinds of certifications should I consider for a Systems Analyst career?

These workers figure out how to use computers to get things done. They tell businesses and other organizations which computers and software to buy, and they decide how to get those tools to work together. To qualify on this position, you must have:

• A four-year college degree in computer science, information science, or management information systems.

• Microsoft Certification and Microsoft Certified Professional (MCP)

* What kinds of certifications should I consider for a Systems Engineer career?

Systems engineering is like putting together a puzzle, matching varied pieces together to make one cohesive whole. Here are some certifications you need to comply:

• BS in systems engineering or other related engineering discipline or an equivalent combination of education and work related experience.

• Novell certifications

Earning computer certification at a prestigious educational institution is impressive. But, if you don’t have that kind of money, you may take computer certification training courses anywhere and anyway you wish and then pay to take the exams. Passing the exams is what earns computer certification.

* What kinds of certifications should I consider for a Technical Instructor career?

As a technical instructor, you need to be mature and very oriented towards people. To be considered, you must have the following certifications:

• A four-year degree in a computer-related discipline is required for most software engineering positions.

* What does certified mean?

There are four accepted meanings of the adjective “certified” but only two of which satisfy the needed meaning. To be certified means to be endorsed with authority by an institution or a person with higher position after one successfully meets certain requirements. Another meaning is that a person is qualified to do a certain job as supported by an appropriate document better known and regarded as a Certification.

* What certifications are there?

If you are pertaining to online certifications, there are lots to be traced. To help you find one best certification that fits your ability and interest, you may log on to reliable sites in the internet. For now, the following are the basic IT certifications:

• IT Auditing
• Document Imaging
• E-Commerce
• Internet/Intranet
• Linux
• Networking
• Printing
• Project Management
• IT Security
• Servers
• Service Technician
• Technical Trainer
• Webmaster

* Who benefits from certification?

Primarily the one given a certification benefits more. Being certified means one can properly function on a certain job. This means, companies will easily hire a person with certification especially when certifications come from a reliable learning institution.

In some ways, the company to which a certified person intends to apply for work will also benefit since the performance of the applying employee is being supported with a certification.

* Is certification better than experience?

The answer for that is a big “No.” Certification means training. It is impossible for a person to send himself training without experiencing what it is he intends to do. For this reason, we cannot equate certification from experience since they do not share the same purpose. However, if you already have work experience, a certification is a big help for promotion, recognition and pay raises.

On the other hand, companies are not solely after experience but after educational attainments and performances. In other words, having completed a course as proved by a certification is a chance to be hired.

Like TCP, BGP is connection-oriented. An underlying connection between two BGP speakers is established before any routing information is exchanged. This connection takes place on TCP port 179. As with EIGRP and OSPF, keepalive messages are sent out by the BGP speakers in order to keep this relationship alive.

Once the connection is established, the BGP speakers exchange routes and synchronize their tables. After this initial exchange, a BGP speaker will only send further updates upon a change in the network topology.

The IGP protocols that use Autonomous Systems, IGRP and EIGRP, require prospective neighbors to be in the same AS. This is not true with BGP. Routers can be in different Autonomous Systems and still exchange routes. The BGP neighbors do not have to be directly connected, and often are not, but do need to be able to reach the IP addresses they use in their neighbor statements.

A BGP peer that is in the same AS is referred to as an Internal BGP (iBGP) Peer, where a BGP peer in another AS is an External BGP (eBGP) Peer.

A sample iBGP configuration:

Router bgp 100

Neighbor 10.1.1.2 remote-as 100

A sample eBGP configuration:

Router bgp 100

Neighbor 10.1.1.2 remote-as 200

Cisco recommends that eBGP peers be directly connected, where iBGP peers generally will not be.

Before we get too much farther into BGP theory, let’s get a configuration started. You’ll use the router bgp command to configure a router as a BGP speaker. Right after that, the neighbor command will be used to identify this BGP speaker’s potential neighbors. (The terms “peer” and “neighbor” are interchangeable in BGP, but it’s the neighbor statement that is used to statically define neighbors. BGP is not capable of discovering neighbors dynamically.)

R1(config-router)#neighbor 172.12.123.3 remote-as 200

While almost all of the neighbor options are just that — optional — you do have to specify the BGP AS of the remote router. BGP has no mechanism to dynamically discover neighbors. Remember, BGP speakers do not have to be in the same AS to become peers. To verify that the remote BGP speaker has become a peer, run show ip bgp neighbor.

Passing the BSCI exam and earning your CCNP is all about knowing the details, and when it comes to EIGRP SIA routes, there are plenty of details to know. A quick check in a search engine for “troubleshoot SIA” will bring up quite a few matches. Troubleshooting SIA routes is very challengin in that there’s no one reason they occur.

View the EIGRP topology table with the show ip eigrp topology command, and you’ll see a code next to every successor and feasible successor. A popular misconception is that we want these routes to have an “A” next to them – so they’re active. That’s what we want, right? Active routes sound good, right?

Well, they sound good, but they’re not. If a route shows as Active in the EIGRP topology table, that means that DUAL is currently calculating that route, and it’s currently unusable. When a route is Passive (“P), that means it’s not being recalculated and it’s a usable route.

Generally, a route shown as Active is going to be there for a very short period of time by the time you repeat the command, hopefully that Active route has gone Passive. Sometimes that doesn’t happen, though, and the route becomes SIA – Stuck In Active.
