vSAN iSCSI Target Service

B.

Sure, I'd be happy to explain each answer choice in detail:

A. It is a VMware supported cost effective way to provide shared storage to another hypervisor. This answer is true. The vSAN iSCSI target service allows you to present vSAN storage as an iSCSI target to other hypervisors or physical servers. This is a cost-effective way to provide shared storage without requiring additional hardware. The iSCSI target service is included with vSAN, so there are no additional costs to use it.

B. The vSAN default storage policy determines the characteristics of the vSAN iSCSI target service storage objects. This answer is false. The vSAN default storage policy does not determine the characteristics of the vSAN iSCSI target service storage objects. Instead, you can create custom storage policies for iSCSI targets that specify things like the number of replicas, the cache tier, and the stripe width.

C. Security is provided through the iSCSI CHAP & Mutual CHAP Authentication methods. This answer is true. The vSAN iSCSI target service supports both iSCSI CHAP (Challenge Handshake Authentication Protocol) and Mutual CHAP authentication methods to provide security for iSCSI traffic. CHAP is a mechanism for authenticating the initiator (client) and the target (server) in an iSCSI session.

D. It is a VMware supported solution to provide iSCSI targets to applications that require multiple connections per session (MCS). This answer is false. The vSAN iSCSI target service does not support Multiple Connections per Session (MCS). MCS is a feature of iSCSI that allows multiple TCP connections to be established between an initiator and a target to increase performance. However, the vSAN iSCSI target service does support Multiple Sessions per Connection (MSPC), which allows multiple iSCSI sessions to be established over a single TCP connection.

I hope that helps! Let me know if you have any more questions.
