An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.
Which plan meets the customer requirements?
To ensure that the Mobility Master (MM) remains available in case of a total site failure at the primary location, deploying a hardware MM to the disaster recovery site and setting its IP address as the standby master for the Mobility Controllers (MCs) meets the requirement. This approach ensures that the MM can take over management duties seamlessly in the event of a failure at the primary site. VRRP is not suitable for Layer 3 redundancy across different sites, and clustering does not provide the necessary Layer 3 MM redundancy.
Answer should be B both sites are connected in L3
Answer is B see eBook ACDP Chapter 7 Redundancy
it should A. It mention on ACDP book and ACMP
- just interested where in the ACDP book I can find this - can you note the reference page or the wording please
Its B, because disaster recovery its fail all MM if you need recovery all i think this for Review Aruba 8.X Architecture.
A is incorrect because the MC's don't know about it B is correct, you set up L3 redundancy this way C incorrect, can't VRRP across L3 D incorrect clustering does not setup L3 redundancy
It seems B is correct. This Aruba KB gives more insight to the scenario https://www.arubanetworks.com/techdocs/ArubaOS_86_Web_Help/Content/arubaos-solutions/vrrp/conf-stby-mm-l3red.htm
B: In the event of an MM outage, MCs continue to use their existing licenses for 30 days, and the network remains up. However, you cannot change the configuration items in the controller network. In addition, the MM manages many of the higher level functions that can cause issues in the network if the MM fails. Aruba recommends a backup MM for these situations. From an economic point of view, a backup MM for a VMM is free. If a customer has a hardware MM, the customer must purchase a backup hardware MM.
B is correct
