   An administrator has a Wide IP with topology records that send traffic from the US to 'Pool_US' and from Europe to 'Pool_EU'. They need to temporarily send all traffic from a specific US state (e.g., Texas) to 'Pool_EU' for testing purposes. What is the most efficient way to achieve this?

   • AUse an iRule to check the client's source IP and select 'Pool_EU' for all requests.
   • BModify the existing US topology record to point to 'Pool_EU'.
   • CCreate a new, more specific topology record for Texas that points to 'Pool_EU'.
   • DChange the Wide IP's load balancing method to 'Static Persist' and configure a persistence record for Texas.

   A company has two data centers, each with a set of virtual servers that can handle the full expected traffic load. Which configuration best provides redundancy and capacity?

   • ATwo separate pools, each with a different load balancing method.
   • BTwo separate pools, one per data center, with no Wide IP configuration.
   • CA single pool containing all virtual servers from both data centers.
   • DA single pool with only one virtual server from each data center.

   What is the primary difference between topology-based load balancing at the Wide IP level versus the pool level?

   • AWide IP topology selects among pools, while pool topology selects among members within a pool.
   • BWide IP topology is used for DNS responses, while pool topology is used for HTTP redirects.
   • CWide IP topology is based on the client's IP address, while pool topology is based on the server's IP address.
   • DWide IP topology uses geographic data, while pool topology uses network data.

   How can an iRule affect load balancing at the Wide IP level?

   • AAn iRule can only affect load balancing at the pool level, not the Wide IP level.
   • BAn iRule can select a specific pool for a DNS query based on custom logic.
   • CAn iRule can disable the Wide IP entirely.
   • DAn iRule can change the DNS TTL for the Wide IP.

   In BIG-IP DNS, what is the role of a topology record?

   • AIt defines the order in which load balancing methods are tried.
   • BIt maps a client's geographic or network location to a specific pool or member.
   • CIt defines the DNS TTL for the Wide IP.
   • DIt stores the health status of virtual servers.
