IPS filter on Policy ID with multiple protocols

Hi 

I have following question

Lets assume we have a firewall policy permitting Windows Active Directory Traffic (which resulst various TCP, UDP protocols).

Ifr for example I create an IPS filter containning these protocols , when requests reach firewall all traffic will be inspected by IPS filter for any protocols , OR 

example : if it is DNS traffic, only DNS replated IPS signatures will scan packets ?

Example: One IPS filter for DNS + LDAP, + NTP +ICMP

if for example I ping an IP address , by maching rule with this IPS filter, packet will be inspected for all protocols above or ICMP only ???

Thanks
