Question
An engineer must design a disaster recovery solution for a Cisco ACI Multi-Site network. One requirement is that the applications must have seamless IP addressing across sites. The solution must also be highly resilient and support Layer 2 adjacency. Which design meets these requirements?
Options
- Alocalized bridge domain, subnet, and EPG
- Bstretched bridge domain with local subnet
- Clocalized bridge domain with local subnet
- Dstretched bridge domain, subnet, and EPG

Explanation
Cisco ACI Multi-Site supports disaster recovery scenarios where IP mobility across sites is required. This means the same IP subnet is stretched across the two sites for seamless IP addressing, which requires a stretched bridge domain and subnet. Stretched bridge domain, subnet, and EPG This enables the same Layer 2 and IP subnet to span across multiple sites, allowing seamless IP addressing and mobility of workloads without changing IP addresses. Localized Layer 2 broadcast flooding To improve resilience and reduce unnecessary broadcast traffic, Layer 2 broadcast flooding is localized within each site. This avoids performance and stability issues caused by Layer 2 broadcast traffic spanning wide areas.
