No. CNAME's are a one-to-one mapping between a name and another name. A records are one to many mappings between a name and one or more IP addresses.<br />
<br />
Yes, you'd need to delete the production record when the production server goes down.

<div class="content wysiwyg-content">
I have an Application running on server1.domain.com. And I have a CNAME for my application as Myapps.domain.com to serverA.domain.com.<br />
<br />
<br />
Users access the application by using Myapps.domain.com.<br />
<br />
I am planning to put a DR for this website on Server2.Domain.com in different city.<br />
Now I want to setup something like MX record priority like…if my Server1.domain.com fails then it should automatically go to my DR server Server2.Domain.com.<br />
<br />
How to setup this…Should I put Two CNAME pointing to server1 &amp;&nbsp;server2.<br />
<br />
How it is going to work ?<br />

DNS CNAME records for DR purpose...
