Man, I wouldn't think that would prevent a renewal. It does. Depends on race conditions, but it definitely happens. I guess I need to re-read up on the DHCP process - I thought (at least with Windows) that the client machine did a check at the 50% timeframe and renewed then, thereby never actually reaching an expired state. But that was 20+ years ago when I read the MS docs on it... so I could have a faulty memory. It does, but machines powering on and off and such can disrupt that process. uh, what? Sure, now if a machine is off, and the half way point, or the full expire time hits, sure, when the machine comes back online - it has to basically start over... The OP says the machine is loosing it's IP what appears to be overnight. OK, so let's assume the lease expired while the computers were in powersaver mode, or simply off. I would expect them to be turned on and simply go through a DHCP request - but the OP says a reboot it required to get back on the network. so something isn't working from the client side. So the NIC has been updated and that didn't solve it. Any chance the switch could be the culprit? Are there updates available for the switch?

@mary said in Optical Fiber Connectors - CompTIA Network+ N10-007 Prof. Messer: Is there a standard connector? Are they manufacturer dependent? There are standards, but many of them. There are a few that are pretty broadly standard, and generally manufacturer independent, but not always. You tend to buy from the manufacturer of your switch or whatever device it is.

@JaredBusch said in Optical Fiber - CompTIA Network+ N10-007 Prof. Messer: umm maybe a decade ago... Fiber is cheap and not all that complicated to have terminated anymore. We've been called in because dev firms and their normal IT support could not figure out the parts and connectors. It might seem easy to you and me, but to a normal SMB without a dedicated networking team, it's often hella confusing.

@Dashrender That's what she....

So chances are you will never run or even see an NTP master. But you might run or see an NTP relay, almost certainly. You saw me turn one off (pillow over its face) over the weekend.

@mary said in Cloud Services and Delivery Models - CompTIA Network+ N10-007 Prof. Messer: At what point is it worth having your own data center? I would think the cost of it wouldn't be worth it for most. Your own, meaning you own the facility rather than colo? That one is pretty easy.... You would go to your own datacenter when the cost to get the features you need from colo exceeds the cost to build and maintain your own (this would likely happen at around 15-60% of filling a single colo location.) And your staffing needs will play into this, if the colo has 24x7 support, and you only need 16x6, you might lower your own cost that way. This is assuming you don't need the flexibility of putting equipment in and out from time to time or using multiple sites for it, like colo easily allows.

@mary said in Wireless Network Technologies - CompTIA Network+ N10-007 Prof. Messer: Do the frequencies used self modulate within the router? What I'm wondering is if when setting up a dsl connection if it automatically defaults to a specific frequency or is it constantly switching. DSL is the wired bit. Wifi is from the access point. And this will depend on the protocol chosen. 802.11 b for example requires thebfrequency be set.
