A global e-commerce company has data centers in Frankfurt and Singapore. The network team has defined a topology region named 'EU-Core' that must include the 10.10.0.0/16 subnet range used by their Frankfurt office. They also want a region named 'APAC-Core' for the 192.168.0.0/16 range used in Singapore. The BIG-IP DNS administrator needs to create these custom regions so they can later be used in topology records. Which action should the administrator take to define these regions?

Create a topology region named 'EU-Core' with the IP prefix 10.10.0.0/16 and a region named 'APAC-Core' with the IP prefix 192.168.0.0/16.

Define the regions by creating a new DNS listener for each subnet and assigning it to a pool.

Create a single topology region named 'Global-Core' and add both 10.10.0.0/16 and 192.168.0.0/16 as IP prefixes within it.

Use the standard built-in regions 'Europe' and 'Asia' and map the subnets to them via a topology rule.

If a topology rule matches a client region but the load balancing mode is set to 'round robin', what determines which pool member receives the DNS response?

The pool member with the highest configured ratio.

The first pool member in the pool list regardless of topology.

The next pool member in the rotation order among those in the matched topology region.

The pool member with the lowest current connection count.

A client in the 'West' region queries a wide IP. The topology rules specify that clients in 'West' should use the 'West-Pool'. The 'West-Pool' has two members: 10.1.1.1 and 10.1.1.2. The load balancing mode is 'round robin' and this is the first query. What IP address will BIG-IP DNS return?

No response because topology rules override load balancing.
