Cisco CCNP Security Core (SCOR) 350-701Cloud SecurityHard
A large enterprise is designing a highly available and secure multi-cloud architecture. They need to ensure that their applications can failover seamlessly between different cloud providers in the event of a regional outage or security incident, while maintaining consistent security posture. Which architectural pattern is most suitable for this stringent requirement?
- ACloud Bursting
- BLift and Shift
- CHybrid Cloud
- DActive-Active Multi-Cloud
Show answer & explanationAnswer & explanation
Correct answer: D. Active-Active Multi-Cloud
Active-Active Multi-Cloud involves running applications simultaneously across multiple cloud providers. This design inherently supports seamless failover and high availability across providers, allowing for resilience against outages or security incidents in a single cloud region or provider, while demanding consistent security implementation across all active environments.
Why the other options are wrong
- A. Cloud Bursting extends capacity from on-premises to cloud during peak loads, but doesn't provide active failover between *different cloud providers*.
- B. Lift and Shift is a migration strategy, not an architectural pattern for multi-cloud failover or consistent security posture across providers.
- C. Hybrid cloud connects on-premises and cloud, but doesn't inherently provide seamless failover *between* different cloud providers.
Active-Active Multi-Cloud
An architectural pattern where an application runs simultaneously across two or more distinct cloud providers, with traffic distributed between them, enabling high availability, disaster recovery, and resilience.
- Workloads are active in multiple cloud environments concurrently.
- Provides immediate failover capabilities between providers.
- Requires consistent security policies and configurations across all active clouds.
Memory trick: Active-Active: Multiple clouds, all running, ready to switch instantly.
