Is A because Short for load-reduced dual inline memory module. LRDIMM is a load-reduction (LR) DIMM (used in servers) that supports higher densities than RDIMMs and contains a memory buffer (MB) chip, as opposed to a register, in order to reduce and minimize the load on the server memory bus.

I do believe the A+ core 1 objectives do not cover LRDIMM. It does however cover DDR4. Assuming the answer is actually LRDIMM, the question most likely would be one of added questions that do not count towards your overall score. Best guess to save face in my opinion would be DDR4 being that it is a viable option in this situation depending on unspecified information. Hope that made sense. CompTIA gives you exam objectives for a reason.

If it is a server-grade laptop than it should be compatible with LRDIMMs. ------------------------------------- "Short for load-reduced dual inline memory module.

the answer is correct. DDR4. LRDIMM has high latency, which the boss can't afford.

You all have to consider if LRDIMMs are made to be used for laptops.

I don't think laptop will support LRDIMM.

same issue here as with a previous question. I strongly feel it should be a module that has RAM parity since we're dealing with a server. You wouldn't be able to "choose" DDR4 ram as you are locked into the type by the system board.

I agree with you and may the laptop need DDR3 not 4. The parity is very old, but it makes sense here.

You could, however, be upgrading from 8 GB DDR4 to 16 GB DDR4. This question is terrible. Undetected memory errors can result in no consequences, or permanent corruption of data/machine crash. Parity will only detect the error and not correct it. For correction on the fly you need ECC. When a parity error is detected, the motherboard parity-checking circuits generate a nonmaskable interrupt (NMI), which halts processing and diverts the system's attention to the error. In some older systems, parity-check routine halts the CPU and causes the system to lock up, leaving you to perform a hardware reset. Meaning all your work is lost. The idea for parity is to catch RAM errors before they become catastrophic and allow you to schedule downtime to replace it. Most systems don't halt the CPU when parity error is detected; instead, they offer the choice of rebooting the system or continuing as though nothing happened. Parity will not reduce downtime and is not a "type of RAM" but a FEATURE built into certain TYPES of RAM. LRDIMMs are a load-reduction DIMM used in servers to reduce load on the server memory bus. This has noting to do with preventing downtime.
