There's this thing called "Google". I plugged DDOS into it and found this:

Amazing how 'teh intwarweb' works, huh?

 

alih786 what is this for?

As above google is a good resource for information.

 

McCormick's Law of Troubleshooting:

"Google first and ask questions later."

Folks... Google is one of the most important tools in your kit. You'll need it to look up symptoms, error messages, EVENT IDs, missing DLLS, find drivers, etc. If you are unable to look up the simplest thing on teh intarweb then you simply will not cut it as any sort of tech.

Period.

On Tuesday a customer dropped off an Acer notebook. She said it was working, then there was a click and the unit turned off. It subsequently refused to power up.

So I googled it.

Turns out that when an Acer notebook's battery starts to age, it can sometimes draw too much current. This causes an internal circuit breaker to trip (the click). The solution is to remove the battery and wait ten minutes for the breaker to reset. I did so and heard a click somewhere near the ten minute mark. Now the system powers up again and I've got $54.95+tax in my pocket from a grateful customer who badly needed her notebook for work.

All this from being able to type a sentence into a search engine.

 

Good example mate, but some people just want people to answer them ibecause they can't be bothered to figure out the answer themselves.

 

And those are the people who shouldn't be in IT. Not saying that's the case with alih786... hopefully, ali will recognize the importance of using Google to its fullest extent.

 

Although I don't like spoon feeding, I'll answer. I believe the answer is B. A DDoS is two or more (possibly thousands) of infected machines that are all requested (remotely) to attack a single target. A DoS is an attack from a single host, against another. This is the Black & White answer, anyway.

 

I don't guess you read choice A, then.

 

Well A is how the attack happens and B is what happens because of the attack even I know this, but it depends on how you read the question. The way ali has put it I would say A, but if its a two option jobby then it has to be A and B.

 

Er - <cough> B is a completely wrong statement!

Daemons are the Unix equivalent of Windows services. Programs that run in the background with no terminal or window associated.

Computers will normaly run many daemons, but they aren't daemons in their own right!

Harry.

 

I though daemons is what they're called

 

They may be the very devil to deal with!

This is a typical misdirection type answer option. Make if look vaguely possible, unless you know your stuff.

Harry.

 

GBL check this out..

http://en.wikipedia.org/wiki/Daemon_(computer_software)

 

It's A, but I 'm surprised it's in the A+ threads... surely this should be in the Sec+...

 

Er - you may want to check the Objectives - particularly Domain 6.

Harry.

 

I would have chosen A anyhow, but B would have made me think. But I would have been wrong cheers Harry.

 

Ouch.

Wrong answer.

 

Yes, yes, yes! I meant 'A'. I typed my answer whilst being at work doing some real, hard, customer services - unlike you lazy network and PC admins ;)

I meant A as being the correct answer. Now I look stupid. I'll refrain completely from answering in the future.

 

Why? Because some folks corrected you? It’s the best way to learn. I’ll bet you’ll never make that mistake again. Whether it was the wrong answer or just a typo, you’ll know better for next time.

As for the folks that pointed out the error, nobody really mocked you. Instead the answer was provided with explanation. What more could you really want? Realize what could have been said and you’ll see this is a pretty forgiving place - so long as you try.

 

QFT, I have replied to answers in the past where I have been wrong and thus been corrected. I would prefer someone correct me so I learn from my mistake.

rep for ya
