Exam 220-1101 topic 1 question 488 discussion

The clicking sound coming from the area where non-volatile storage is installed is a common symptom of a failing mechanical hard drive (HDD). This issue typically indicates that the read/write heads or the internal mechanical components of the HDD are malfunctioning. Replacing the faulty HDD with another 7,200rpm HDD, which matches the specifications of the original drive, is the most appropriate solution.

I understand that NVMe SSD would be the "best" option, but that would be an upgrade and we are jumping to a conclusion that this laptop even has the ability to accept one. I am dying on the hill of answer choice A, 7,200rpm HDD.

B is correct A is wrong NVMe stands for Non-Volatile Memory Express, and it is a type of SSD (solid state drive) that uses PCIe (Peripheral Component Interconnect Express) interface to connect to a computer. NVMe SSDs offer faster performance and lower latency than other types of SSDs, such as SATA (Serial ATA) or M.2 SATA. If a user reports that a PC occasionally fails to boot and makes clicking sounds in the area where non-volatile storage is installed, it indicates that the hard drive is failing and needs to be replaced with an NVMe SSD

The question asks for a REPLACEMENT, not an UPGRADE. A clicking sound is from a failing HDD so we know we are replacing a HDD. 15,000 RPM HDDs are not used in laptops and the only remaining answer that is HDD is A.

B. NVMe SSD is the most appropriate replacement part. NVMe SSDs (Non-Volatile Memory Express Solid State Drives) are known for their high performance and reliability. They offer significantly faster read and write speeds compared to traditional HDDs and SATA SSDs, which can help to alleviate the clicking noise and improve overall system performance. Here's why the other options are less suitable: A. 7,200rpm HDD: While HDDs are more affordable, they are slower and more prone to mechanical failures, which can lead to clicking noises. C. M.2 SATA SSD: While M.2 SSDs are faster than traditional HDDs, they are still limited by the SATA interface. NVMe SSDs offer significantly better performance. D. SCSI 15,000rpm HDD: SCSI drives are high-performance drives, but they are more expensive and less common than NVMe SSDs. They are also prone to mechanical failures. By replacing the failing drive with an NVMe SSD, the technician can improve the laptop's performance and reliability. GG

Clicking sounds are HDD not SSD

The replacement part is an HDD, which means A or D. However it is a laptop. A SCSI 15000 rpm HDD is best suited for a server. Hence, I believe the correct answer is A. 7200 rpm HDD

Nope - read the question guys. Its asking about replacement parts. The HDD has failed, bro takes it out and if he were to get a NVMe or SSD where is he going to put it? The guy has a dodgy HDD so they have to replace the HDD on the same connector as the one they just took out. Hence I would say either A or D. In this case its probably D as its SCSI that is making the noise since its much older.

NVMe SSDs (Non-Volatile Memory Express Solid State Drives) are known for their reliability, speed, and lack of moving parts, making them less prone to mechanical failure and clicking sounds compared to traditional hard disk drives (HDDs).

It`s B
