Layer 3 virtualization refers to the use of technologies that enable multiple virtual networks to run on a shared physical infrastructure. These technologies provide isolation, scalability, and security benefits to network operators. However, there are some design concerns that should be accounted for in all Layer 3 virtualization technologies.
The correct answer to the question is A. Layer 3 redundancy. Layer 3 redundancy refers to the ability of the network to provide backup paths for traffic in case a link or a device fails. In Layer 3 virtualization, multiple virtual networks run on the same physical infrastructure. Therefore, any failure in the physical network could affect multiple virtual networks, leading to downtime and service disruption.
To address this concern, Layer 3 virtualization technologies should incorporate redundancy mechanisms that provide fast failover and minimize disruption to the virtual networks. For example, Virtual Router Redundancy Protocol (VRRP) or Hot Standby Router Protocol (HSRP) can be used to provide backup paths for traffic in case of a router failure.
Packet sizing and application usage are not design concerns that are specific to Layer 3 virtualization technologies. Packet sizing refers to the process of optimizing the size of network packets to improve network efficiency, while application usage refers to the monitoring and control of application traffic on the network.
Layer 3 stability is an important concern, but it is not unique to Layer 3 virtualization technologies. Layer 3 stability refers to the ability of the network to maintain stable routing and forwarding behavior, even in the presence of network changes or failures. This is a concern for all network technologies, not just Layer 3 virtualization.
In summary, Layer 3 redundancy is a crucial design concern that should be accounted for in all Layer 3 virtualization technologies. This ensures that the virtual networks can maintain uptime and service availability, even in the event of network failures.
