CS 469 Final Exam

CS 469 Final Exam I hate computers Name: Section: 1.) JOHN is attempting to use a Thunderbolt® 3 DOCK. The DOCK claims to support USB-PD (Power Delivery) rated at 60W, encapsulated PCIE for an eGPU, gigabit Ethernet, and DisplayPort + HDMI 2.1 video output. a. What are the odds that the moment JOHN plugs in the DOCK (containing an eGPU), his laptop will immediately kernel panic? (Hint: it’s 1) b. The DOCK features a Gigabit NIC vendored by Realtek. What is the probability that this shitty Realtek NIC will intermittently stop working, with no real workaround? For full credit, show your work: c. The cable which came with the DOCK is too short for JOHN’s STANDING DESK. If JOHN then uses an EXTENSION CABLE (3m, supposedly rated for TB4®), will it work? No of course it won’t this shit is black magic. I swear these guys never get it right, they just copy paste the same pirated IP blocks and fuck it up

A parody computer science final exam asks JOHN to troubleshoot a Thunderbolt dock packed with unreliable hardware and compatibility problems. The punchline is that every answer is effectively “it will fail,” mocking buggy Realtek networking, kernel panics, short cables, and mysterious hardware standards.
