Explanation

Cisco Global Site Selector (GSS) is a DNS-based global load balancing and disaster recovery solution. It monitors site health and, if a site goes down, redirects DNS responses to a healthy site, providing traffic rerouting in the event of a disaster (Choice B). It also acts as an authoritative DNS server with centralized domain management, reducing DNS query latency and improving DNS responsiveness (Choice E). Choice A is incorrect-GSS does not perform end-to-end path verification; it uses keepalives to check server and site availability but not full path tracing. Choice C is incorrect-HSRP, GLBP, and VRRP are first-hop redundancy protocols for gateways, not GSS clients. Choice D is incorrect-GSS works independently of the routing protocol; BGP is not required between data centers.
