Correct! A hypervisor manages and allocates physical resources from the bare metal host to create multiple VMs. It provides virtual isolation while sharing underlying hardware resources.
Incorrect. A hypervisor (virtualiser) is the technology that runs on bare metal servers to split physical resources into multiple isolated virtual machines.
Exactly! VMs are ideal when your research requires more computational power, specialised hardware (like GPUs), specific software environments, or when running processes that would tie up your local machine for extended periods.
Incorrect. VMs are most valuable for computationally intensive research tasks that exceed local machine capabilities, including large-scale analysis, machine learning, and specialised software requirements.
Perfect! Creating a VM requires selecting a compute shape (CPU/memory), configuring networking (virtual network/subnet), attaching storage (managed disk), choosing an OS image, and setting up authentication (SSH keys or passwords).
Incorrect. A complete VM setup requires all five components: compute shape, networking, storage, OS image, and authentication credentials to function properly.
Correct! SSH key pairs provide much stronger security than passwords by using cryptographic authentication, making them virtually immune to brute-force attacks and eliminating password-based vulnerabilities.
Incorrect. SSH keys offer superior security through cryptographic authentication, making them highly resistant to password-based attacks and brute-force attempts.
Perfect! The module covers auto-shutdown configuration to prevent VMs from running unnecessarily, and proper resource cleanup by deleting VMs and associated resources when projects are complete.
Incorrect. The key cost management strategies are implementing auto-shutdown to prevent unnecessary running time and properly deleting resources when they're no longer needed.
