yes:
mx records are in DNS servers, not in exchange servers, so your question is a little but confusing.
DNS records should be duplicated. over 2 or more public available DNS servers. Normally this is someting you let someone host for you.

It is possible to create 2 MX records with different priority. If the first server does not response in time, than the second server will be used.
You need 2 different public IP's to do this, if you have redundant internet lines (with different providers), it is recommended.
If you have 2 Internet facing Exchange Edge servers, you should forward port 25 of those 2 ip's to each one of them. Those edge servers can then do the content filtering en forward mails to your internal exchange server(s).

Robby explained one option but on dns you have the roundrobin option as well. Means you can set 2 or mor entries with the same priority then the client who is asking for the ip of your mail server gets one of these entries. Is a kind of loadbalancing as well. The question is only can you handle that with your mail servers?

We made it by putting a web appliance in front. Like a antivirus gateway. This appliance is able in loadbalance cluster. So in our mx we have three ips in roundrobin.
