Zorluk: KolayResilience, High Availability, and Redundancy

An enterprise organization installs two independent Internet Service Provider (ISP) lines connected to a perimeter router. If the primary connection experiences an outage, network traffic immediately routes through the secondary line to prevent network disruption. Which of the following resilience concepts is best demonstrated in this scenario?

  1. Link redundancyCevap
  2. B
    Off-site data backup
  3. C
    Corrective administrative control
  4. D
    Non-repudiation mechanism

Cevap

Link redundancy
Link redundancy involves deploying multiple connection pathways so that if one provider or physical line fails, traffic automatically fails over to an operational link, eliminating single points of failure for network connectivity.

Adım Adım Çözüm

1
Analyze the operational objective in the scenario.
The goal is to prevent network outages by establishing multiple independent internet connections.
The enterprise needs uninterrupted connectivity if a single provider connection fails.
2
Evaluate the architectural control deployed.
Installing dual ISP connections introduces redundant connectivity paths at the perimeter.
Redundancy ensures there is no single point of failure for internet routing.
