 ### <a name="network-requirements"></a>Network requirements 
 
-Azure NetApp Files SMB, dual-protocol, and Kerberos NFSv4.1 volumes require reliable and low-latency network connectivity (less than 10 ms RTT) to AD DS domain controllers. Poor network connectivity or high network latency between Azure NetApp Files and AD DS domain controllers can cause client access interruptions or client timeouts.
+For predictable Active Directory Domain Services operations with Azure NetApp Files volumes, reliable and low-latency network connectivity (equal to or less than 10 ms RTT) to AD DS domain controllers is highly recommended. Poor network connectivity or high network latency between Azure NetApp Files and AD DS domain controllers can cause client access interruptions or client timeouts.

+>[!NOTE]
+>The 10ms recommendation adheres to guidance in [Creating a Site Design: Deciding which locations will become sites](/windows-server/identity/ad-ds/plan/creating-a-site-design#deciding-which-locations-will-become-sites).
 
 Ensure that you meet the following requirements about network topology and configurations:
 
 * Ensure that a [supported network topology for Azure NetApp Files](azure-netapp-files-network-topologies.md) is used.
 * Ensure that AD DS domain controllers have network connectivity from the Azure NetApp Files delegated subnet hosting the Azure NetApp Files volumes.
     * Peered virtual network topologies with AD DS domain controllers must have peering configured correctly to support Azure NetApp Files to AD DS domain controller network connectivity.
 * Network Security Groups (NSGs) and AD DS domain controller firewalls must have appropriately configured rules to support Azure NetApp Files connectivity to AD DS and DNS.
-* Ensure that the network latency is less than 10 ms RTT between Azure NetApp Files and AD DS domain controllers.
+* For optimal experience, ensure the network latency is equal to or less than 10ms RTT between Azure NetApp Files and AD DS domain controllers. Any RTT higher than 10ms can lead to degraded application or user experience in latency-sensitive applications/environments. In case RTT is too high for desirable user experience, consider deploying replica domain controllers in your Azure NetApp Files environment.
