A few questions from this unit, with the answer and a full explanation. The complete bank is available when you start practising.

1. A user commutes by train and reads for two hours daily in a brightly lit carriage. They are choosing between a 10-inch Android tablet and a Kindle Paperwhite for reading ebooks. Which is better suited for this use case and why?

   • A
     The Kindle Paperwhite, because its e-ink display is front-lit rather than backlit, reduces eye strain during prolonged reading, and offers weeks of battery life on a single charge
     Correct answer
   • B
     The Kindle Paperwhite, because it supports video playback for when the user finishes their book
   • C
     The Android tablet, because it supports a wider range of ebook formats including EPUB natively without conversion
   • D
     The Android tablet, because it weighs less than a dedicated e-reader and is easier to hold for extended periods
   Explanation

   E-ink displays like those on the Kindle Paperwhite are front-lit using edge lighting that illuminates the reflective e-ink surface, producing a paper-like reading experience without the glare and eye strain associated with backlit LCD screens. The Kindle Paperwhite's battery lasts weeks between charges, ideal for daily commute use. LCD tablets produce blue-spectrum light that can cause eye fatigue during extended reading sessions. The key takeaway is that e-ink front-lighting technology makes dedicated e-readers significantly better than LCD tablets for extended, comfortable reading.

2. What type of pixel defect appears as a pixel that is permanently lit in one colour regardless of the image displayed?

   • A
     A ghost pixel
   • B
     A stuck pixel
     Correct answer
   • C
     A dead pixel
   • D
     A burned-in pixel
   Explanation

   A stuck pixel has a transistor that cannot turn off, causing it to remain continuously lit in one or more colour channels (appearing as red, green, blue, white, or combinations thereof) regardless of what the display shows. This differs from a dead pixel, which cannot turn on and appears permanently black. The key takeaway is that a permanently lit coloured dot is a stuck pixel, while a permanently dark dot is a dead pixel.

3. An enterprise mobile management consultant is assessing whether to deploy iPhones or Android smartphones across an organisation. The consultant notes that iOS devices can only be enrolled in Apple's MDM framework, while Android supports multiple MDM approaches. Which Android MDM capability is NOT available on iOS?

   • A
     iOS does not support remote wipe of corporate data on enrolled devices, while Android does
   • B
     Android allows VPN configuration to be pushed via MDM while iOS requires manual VPN setup by the user
   • C
     Android Enterprise allows full device management by a work profile that completely separates personal and corporate data on a personally owned device (BYOD), with the employee maintaining full ownership of the personal profile
     Correct answer
   • D
     iOS does not support app deployment via MDM, requiring all apps to be installed manually by users
   Explanation

   Android Enterprise's work profile (for BYOD scenarios) creates a cryptographically isolated container on the device where corporate apps and data live. The employee's personal data remains completely separate and the IT administrator has no visibility into or control over the personal profile. iOS MDM operates at the device level and does not provide the same dual-persona work profile model natively in the same way. Both platforms support remote wipe, passcode enforcement, VPN push, and app deployment via MDM. The key takeaway is that Android Enterprise's work profile BYOD capability provides a structural personal/corporate data separation that differs from iOS MDM's device-level management model.
