Security best practices in a virtualized network environment would include which of the following? Response:

Using distinct ports and port groups for various VLANs on a virtual switch enhances network segmentation and isolation within the virtualized environment. This practice prevents traffic from different security zones or functions from intermingling, thereby improving security and control by applying specific policies to each segment.

Running iSCSI traffic unencrypted is a security risk as it exposes sensitive storage data to eavesdropping, even if monitored by NIDS.

While adding HIDS to virtual guests is a good security practice, the question asks for a network security best practice in a virtualized network environment, and segmentation (Option A) is more fundamental to network architecture.

Hardening outward-facing firewalls is a general security best practice for any network, but it is not specific to the virtualized network environment aspect of the question, which implies practices within the hypervisor and virtual switch layer.
