Whenever electrical power is being consumed in an IT room or data center, heat is generated. This heat must be removed in order to maintain an optimal temperature for the equipment, and this is usually done through cooling systems such as air conditioning, air economization, liquid cooling, evaporative cooling, and immersion cooling.

I recall that backup devices don’t typically use sensors at all, so I’m leaning towards alarms for this one.

I’m a bit confused. I thought CCTV used cameras, not sensors like laser beams. Could alarms really be the answer?

Hmm, I'm not totally sure about this one. I know audit software is used to verify processing, but I'm not familiar with the specific techniques. I'll have to think this through carefully.

This one seems pretty straightforward. The Scrum Master is helping the team draft the Sprint Backlog, so this would be in the Plan and Estimate phase.

Okay, let me think this through. I know VRRPv3 has some improvements over v2, but I'm not sure which specific ones are being asked about here. I'll have to carefully read through the answer choices.

Okay, I've got this. Customers, shareholders, suppliers, employees, board members, government, and communities are all clearly connected stakeholders. I'll select those.

I was tempted to go with CCTV, but then I remembered that alarms are the ones that really get triggered by all those lasers and pressure pads. Gotta keep an eye out for those pesky intruders!
