Which network traffic is encrypted using IPsec?

According to official Dell PowerStore documentation, native asynchronous replication traffic between PowerStore systems is encrypted using IPsec. By default, this replication traffic is configured to use the management network. While other management traffic, such as access to the PowerStore Manager UI, is encrypted using TLS 1.2, the management network is the default transport for IPsec-encrypted replication data, making it the correct answer.

B. Service network: This term typically refers to the dedicated service LAN ports used by service personnel for direct system access, not for general inter-system data traffic like replication.

C. Internal network: This is a private, non-routable network for intra-cluster communication between nodes. While secure and isolated, official documentation does not specify it uses IPsec for encryption.

D. Storage network: This network carries host I/O traffic (e.g., iSCSI). This traffic is not encrypted with IPsec by default; security is typically managed at the protocol level with features like CHAP for authentication.

Section "Data-in-transit encryption": "Replication traffic between PowerStore systems is encrypted using IPsec." This statement directly confirms that replication traffic uses IPsec.

Section "Replication connection": "By default

replication traffic uses the management network of the system." This reference establishes the link between the IPsec-encrypted replication traffic and the management network.

Section "Replication network": "Replication can be configured on the management network ports or on two of the four ports on the 4-port card." This confirms that the management network is a primary and default path for replication.
