9. A network administrator is looking for a solution to extend Layer 2 capabilities and replicate backups between sites. Which of the following is the best solution?
Answer: B
Data center interconnect is the best solution for extending Layer 2 capabilities and replicating backups between sites.
Data center interconnect (DCI) provides a means to connect multiple data centers, allowing for the extension of Layer 2 networks across geographically separated locations. This capability is essential for data replication and backup processes between sites.
A) Security Service Edge
Security Service Edge (SSE) focuses on integrating security services delivered from the cloud to protect users and data. While it enhances security posture, it does not extend Layer 2 capabilities or facilitate the replication of backups between data centers, making it unsuitable for this requirement.
B) Data center interconnect
Data center interconnect is designed specifically to enable seamless connectivity between different data centers, allowing for Layer 2 extension. This technology supports the replication of data and backups across sites, making it the optimal choice for the network administrator's needs.
C) Infrastructure as code
Infrastructure as code (IaC) is a management approach that automates the provisioning and management of infrastructure using code. While it streamlines operations and deployment, it does not directly address Layer 2 capabilities or data replication between sites, thus not fitting the requirements of the question.
D) Zero Trust architecture
Zero Trust architecture is a security framework that requires strict identity verification for every person and device trying to access resources on a network. Although it enhances security, it does not provide solutions for extending Layer 2 capabilities or replicating backups between data centers, making it irrelevant in this context.
Conclusion
Data center interconnect stands out as the definitive solution for extending Layer 2 capabilities and facilitating backup replication between sites, as it is specifically designed for such purposes. In contrast, the other options either focus on security, automation, or infrastructure management without addressing the core requirements of network connectivity and data replication.
