CompTIA 220-1201 Practice Test 96
Question 950
On a service ticket for Silverline Travel, the team observes: A workstation used for scientific computation requires supported correction of single-bit RAM errors. The supporting record states that the consumer motherboard specifications do not support ECC operation even with an ECC DIMM installed. The desired outcome is to select ECC hardware only where CPU and board support its error reporting. Any configuration change must be reversible and validated on a controlled test device. Which configuration or repair action best addresses the stated requirement?
- Use the correct desktop DIMM rather than forcing a laptop SODIMM into the socket
- Specify a platform that explicitly supports and enables ECC where required
- Select a qualified DDR4 module of a supported configuration rather than DDR5
- Connect through a supported Thunderbolt or USB4 port and rated cable meeting the enclosure requirements
Explanation
Correct Answer
B:
Specify a platform that explicitly supports and enables ECC where required. It corrects the documented cause using the compatible technology and support constraints. The relevant observation is that the consumer motherboard specifications do not support ECC operation even with an ECC DIMM installed. The support goal is to select ECC hardware only where CPU and board support its error reporting; this design action specifically addresses ecc memory error correction compatibility without confusing a different subsystem.
Incorrect Answers
A:
Use the correct desktop DIMM rather than forcing a laptop SODIMM into the socket. That action is appropriate for sodimm versus dimm form factor, normally when a desktop repair requires replacement memory but the spare part comes from a notebook. Here the observed facts require ecc memory error correction compatibility instead.
C:
Select a qualified DDR4 module of a supported configuration rather than DDR5. That action is appropriate for ddr generation electrical compatibility, normally when a replacement RAM order has the correct capacity but the wrong DDR generation. Here the observed facts require ecc memory error correction compatibility instead.
D:
Connect through a supported Thunderbolt or USB4 port and rated cable meeting the enclosure requirements. This action is appropriate for usb-c versus thunderbolt port capability, normally when an external high-bandwidth storage enclosure only negotiates low speed on a laptop USB-C connector. Here the observed facts require ecc memory error correction compatibility instead.
