Key Points Focuses on minimizing downtime and maintaining service accessibility Uses redundancy, monitoring, and failover mechanisms Common in cloud systems, telecom, enterprise IT, and critical infrastructure Supports service continuity and operational resilience goals Involves tradeoffs between uptime, cost, and operational…
Key Points – Marks failed routes as unusable – Used in distance-vector routing – Helps prevent routing loops – Supports faster recovery after topology changes Definition Route Poisoning is a routing technique that advertises a failed route with an invalid…
Key Points – Service Chaining is an ordered sequence of network or security services applied to traffic. – Traffic is steered through defined functions such as firewalls, optimizers, load balancers, or other network services. – Used in cloud networking, security…
Key Points Uses multiple cloud providers Can improve resilience or reduce dependency Requires integration and governance Common in enterprise cloud strategy Definition Multi Cloud is the use of services from more than one cloud provider within a single organization or…
Key Points Prioritizes safety on failure Used in industrial, mechanical, and control systems May stop, isolate, or de-energize equipment Distinct from failover or fault tolerance Confusing fail safe with redundancy or automatic recovery is a common misuse Definition Fail Safe…
Key Points Produces thrust from chemical energy Typically provides higher immediate thrust than electric propulsion Used for maneuvers and launch support Works by combining reactants in a controlled chamber so the reaction creates hot, high-pressure exhaust directed through a nozzle…
Key Points Delivers broadcast or service content directly to premises Uses a satellite-to-receiver access path Common in consumer satellite television and data services Depends on dish alignment and clear sky view Operates without relying on local terrestrial distribution networks Definition…
Key Points Provides alternate path selection when the primary route fails or degrades Supports service continuity during outages or network degradation Common in resilient networks and satellite communications Triggered by outages, degradation, or policy constraints Requires detection mechanisms and backup…
Key Points Covers confidentiality, integrity, and availability Applies to satcom systems and traffic Includes policy, monitoring, and protection controls Combines technical protection, operational policy, monitoring, and recovery measures Maintains trustworthy service and data handling in satellite environments Definition Information Assurance…
Key Points Proportion of frames received with errors Measures frame-level reliability rather than bit-level reliability Used across wireless systems, satellite links, and digital transport Useful when link performance is evaluated in terms of whole frames that survive transmission intact Definition…
