Cheat Sheet
- Core Components of IT Infrastructure -
When tackling which of the following best defines it infrastructure in an IT infrastructure quiz, remember that it covers hardware, software, network resources, and facilities. NIST SP 800-145 outlines these four pillars, from physical servers and virtualization layers to LANs and data centers. Classify each component by its role to boost recall during your IaaS definition quiz.
- Virtualization at the Heart of IaaS -
At the heart of any Infrastructure as a Service quiz is the concept of virtualization, which abstracts compute, storage, and networking resources. For example, AWS EC2 uses the Xen hypervisor to spin up virtual machines on demand, illustrating the pay-as-you-go model. Recall the formula "C+S+N = IaaS" (Compute + Storage + Network) to ace your IaaS definition quiz questions.
- Key Cloud Attributes: Scalability, Elasticity, Multi-Tenancy -
Efficient service design relies on three hallmarks: scalability, elasticity, and multi-tenancy, often memorized as "SEM." Scalability lets you grow resources seamlessly, elasticity lets you shrink them automatically, and multi-tenancy shares infrastructure securely among clients. Link each attribute back to real-world use cases - autoscaling groups in Azure or Google Compute Engine - to solidify your answer in an IT infrastructure quiz.
- Fundamentals of Public Key Infrastructure (PKI) -
Public Key Infrastructure quiz items often hinge on understanding X.509 certificates, certificate authorities (CAs), and asymmetric encryption like RSA. PKI establishes trust by issuing, validating, and revoking digital certificates for secure communications (RFC 5280). Use the mnemonic "CAT-LD": Certificate, Authority, Trust chain, Lifecycle, Directory to nail PKI questions in your public key infrastructure quiz.
- Shared Responsibility and Security Models -
In an IT infrastructure quiz, security frequently focuses on the shared responsibility model in IaaS: providers secure the physical host and virtualization layer, while customers manage guest OS, data, and applications. Industry standards like ISO 27001 and GDPR guide compliance obligations for each party. Reviewing typical SLAs for uptime guarantees (e.g., "Three nines" = 99.9% availability) will give you confidence on your next Infrastructure as a Service quiz.
