It's the epitome of computer science programs. The idea is to teach you the fundamentals of programming. The popular argument is that you could do that with nearly any programming langauge. Yet,...

A lot is the short answer to your question. It all depends on how busy the sites are and what they have on them. Sites running Magento shopping carts take a little more resources than something...

Those comptia certs are okay for teaching you a few things but employers don't recognize them as a qualification.

+1 to that.

An IP phone uses about 5 watts of power. The power supplied is 48 volts DC. Multiply that by the amperage used (usually around .1) and you end up with around 5 watts of power.

The J-series wont even hold a full table with BGP. I wouldn't waste your time either.

ISA server sucks. It's more of microsoft trying to control everything. You should look at something like squid. It runs on a linux box and will store a cache of web content. AFAI, you need to use...

I had 4 of them a few years ago but I think I got a bad batch. 2 of them had problems with the supply.

It usually depends on the infrastructure of the provider. Some invested heavily into fiber and others are still using copper for the LEC. Both are just as "good" from that point of view, but in my...

Check the PVID. On each port, change the PVID to the VLAN number you set for that port. This assumes you are using 802.1q VLANs and not the port based ones.

If 3 of them failed one after another then that DC is overloading those air handlers. The area being cooled is over the amount of BTUs those units are designed for. That is why it is important to...

IPsec always works and there are many routers and firewalls that will do that for you. You will get better performance from a leased option because the latency (ping) will be much lower. You can...

It's actually better than you guys think:

Data center guys are more informal. You usually won't need a degree from a 4 year university. Some certs will always help but it's a lot about having the right expierence. More importantly,...

They are probably doing it that way so malicious code can't reach out to an external server and download files. I have seen this done on dedicated servers, but never shared ones. How would you know...

From what I've heard they are pretty tough. And EXPENSIVE. They arent very common in the industry. Even among Linux shops. Defininetly a plus to employers but the few people I've run into didn't...

I have a few SRX devices in production and we went the routing of using them for basic policies only. We had issue after issue with the VPNs. Stick with the other stuff.

A layer 3 switch is usually just for routing different VLANs between eachother. Meaning, two devices will communication by looking at VLAN tags and routing table in the switch. Unlike layer 2...
