Selected Answer: C

To ensure that Traffic Manager routes traffic for www.contoso.com, you should create a CNAME record that maps www.contoso.com to TMprofile1.trafficmanager.net. A CNAME (Canonical Name) record is a type of DNS record that maps a hostname to another hostname, rather than an IP address. When a client sends a request for the hostname specified in the CNAME record, the DNS server responds with the IP address of the target hostname. In this case, you can create a CNAME record that maps www.contoso.com to TMprofile1.trafficmanager.net, which is the hostname of the Traffic Manager profile. This will allow clients to access the website using the hostname www.contoso.com, while Traffic Manager handles the routing of traffic between AS1 and AS2 based on the configured traffic-routing method. Therefore, the correct answer is C: a CNAME record that maps www.contoso.com to TMprofile1.trafficmanager.net.
