A company has an Aruba 5400R switch, switch 1, at the network core of its campus. This switch routes all traffic for the campus and is the RSTP root. The company now wants to add another Aruba 5400R switch to the core in order to enhance resiliency. The company wants to use the option that provides the best
Layer 2 and Layer 3 resiliency and also the simplest setup.
What should the administrator do to add the new 5400R switch?
To enhance Layer 2 and Layer 3 resiliency with the simplest setup, the administrator should add the new Aruba 5400R switch as a standby member in a Virtual Switching Framework (VSF) fabric with switch 1. This configuration allows both switches to operate as a single logical switch, providing seamless failover capabilities for both Layer 2 and Layer 3, thus improving the overall network resiliency and simplifying the management and setup process.
Correct answer D. Secondary root bridge does not provide L3 redundancy
Answer is D
You are wrong, answer should be C, If the you chose D the new switches will be a VSF member and can therefore not be the "secondary root bridge" cause it would be the primary one.
D: Like Edwin says.
Yes, D. Layer 2 and Layer 3 resiliency with simplest set up.
