The correct answer is D. IRF 1, IRF 2, and IRF 3 combined into a single IRF virtual device. HP supports IRF for multi-site extension. Because it supports connectivity over long-range 10GbE distances, IRF can be extended across dark fiber networks to bring switches dispersed among multiple sites into a single IRF virtual domain.

Question
A company has a data center that hosts multiple tenants. The company is adding a second and third data center. The core of each data center is an IRF virtual switch. These are the IRF connections:
- IRF 1 is the core of the first data center.
- IRF 2 is the core of the second data center.
- IRF 3 is the core of the third data center.
- The three data centers are fully interconnected with dark fiber.
- IRF 1, IRF 2, and IRF 3 have connections to a WAN and to the
Internet. Which option for the connections between the data centers provides the best resiliency and stability?
Exhibit
Options
- AMSTP running on the links
- BSPBM configured across IRF 1, IRF 2, and IRF 3
- Ca link aggregation that consists of all of the links
- DIRF 1, IRF 2, and IRF 3 combined into a single IRF virtual device

Explanation
HP supports IRF for multi-site extension. Because it supports connectivity over long-range 10GbE distances, IRF can be extended across dark fiber networks to bring switches dispersed among multiple sites into a single IRF virtual domain. This approach can be used to extend both LANs and SANs across disparate data centers. Note 1: To create an IRF virtual device we have to connect members together through an IRF link. This link is created between 2 logical IRF ports, which are associated with physical ports in the member switches, that are going to form the IRF virtual device. After a logical switch is created via IRF, member switches create an IRF virtual device, which acts as a single layer 2 switch, layer 3 switch (for all protocols) and shares single management IP Note 2: Dark fiber is optical fiber infrastructure (cabling and repeaters) that is currently in place but is not being used. Intelligent Resilient Framework (IRF) is a proprietary software virtualization technology developed by H3C (3Com). Its core idea is to connect multiple network devices through physical IRF ports and perform necessary configurations, and then these devices are virtualized into a distributed
