Priya needs to move several 6 GB video files back and forth on a single USB flash drive that must be readable and writable on both Windows 11 and macOS without installing extra software. Which file system should she format the drive with?
- AexFAT, because it supports files well above 4 GB and is natively read/write on both Windows and macOScheck_circle Correct
- BFAT32, because it is the most widely supported removable-media format across desktop operating systems
- CNTFS, because it journals writes and both operating systems fully support reading and writing it
- Dext4, because it is a modern journaling file system that stores large media files reliably
Select exFAT for removable media that must carry files larger than 4 GB with native read/write access on both Windows and macOS. The two hard constraints are files over 4 GB and native read/write on Windows and macOS. FAT32 fails the size limit, NTFS is read-only on macOS by default, and ext4 is not natively mounted by either, so exFAT is the only format that satisfies all of them.
Why A is correct: exFAT was designed for flash media, removes the 4 GB per-file limit, and is natively read/write on modern Windows and macOS, meeting every constraint.
Why B is wrong: FAT32 is broadly compatible, which makes it tempting, but it caps individual files at 4 GB, so a 6 GB video will not fit.
Why C is wrong: NTFS handles large files, but macOS mounts NTFS volumes read-only by default, so Priya could not write to the drive without third-party drivers.
Why D is wrong: ext4 is a capable Linux file system, but neither Windows nor macOS mounts it natively, so it fails the cross-platform requirement.

A user phones the service desk because a shared office printer keeps jamming. So the ticket can be tracked and reassigned to another technician if needed, which detail is most important to capture when first logging the ticket?
- AThe technician's own mobile number so the user can bypass the queue and call back directly later
- BThe affected user's name and contact details together with a clear description of the reported problemcheck_circle Correct
- CA guess at the most likely root cause, entered before any diagnosis has actually been carried out
- DThe final resolution steps, which the technician writes in full before starting any troubleshooting
A ticket must first capture who is affected and a clear problem description so any technician can track, contact, and resolve it. A ticketing system tracks work through its lifecycle; without the requester's identity and a clear symptom description, the ticket cannot be triaged, reassigned, or matched to the caller, which is exactly what tracking depends on.
Why A is wrong: It feels helpful and personal, but routing calls around the ticketing system leaves the issue untracked and impossible to reassign.
Why B is correct: Correct: identifying the user and the symptom is the core of a ticket, letting any technician pick it up, contact the user, and track it to closure.
Why C is wrong: Recording a theory looks proactive, but an unverified guess logged as fact can mislead the next technician and is not the priority at intake.
Why D is wrong: Resolution notes matter, but they cannot be known at logging time; writing them before diagnosis records a fix that has not happened.

Priya is redeploying a working laptop SSD to another employee. Company policy requires that the previous user's data be unrecoverable, but the drive itself must stay functional for reuse. Which method should she use?
- ADegauss the SSD using a magnetic degausser rated for the drive's capacity before reassigning it.
- BDelete the existing partitions and perform a quick format of the volume before handing it over.
- CShred the SSD in an approved media shredder and provision a brand-new drive instead.
- DRun the drive's built-in ATA Secure Erase so the flash cells are reset while the SSD stays usable.check_circle Correct
When media must be reused, choose a sanitisation method such as Secure Erase rather than a destructive method or a superficial format. Reuse rules out physical destruction, and SSDs are immune to degaussing because they use non-magnetic flash storage, so a controller-level Secure Erase is the correct sanitisation that preserves the drive.
Why A is wrong: Degaussing is tempting because it works on magnetic media, but an SSD stores data in flash cells that a magnetic field cannot erase, so the data survives.
Why B is wrong: A quick format only clears the file table, so the underlying data remains and is trivially recovered with forensic tools, failing the unrecoverable requirement.
Why C is wrong: Shredding does make data unrecoverable, but it destroys the drive and defeats the stated requirement to reuse the same SSD.
Why D is correct: Secure Erase issued to the SSD controller sanitises every cell, including spare blocks, and leaves a fully working drive that can be reissued.
