Correct : A, D

When configuring SFTP backups for SDDC Manager and NSX Manager in VMware Cloud Foundation, the following prerequisites must be met:

1. Manually import the SSH fingerprint: Importing the SSH fingerprint of the SFTP server is required to establish a secure, trusted connection between the backup system and the SFTP server.

2. A user with the ADMIN role: An ADMIN role is required to configure backup settings in SDDC Manager, as this role provides the necessary permissions to access and modify backup configurations.

Options related to specific key lengths (256-bit or 512-bit ECDSA) are not requirements for configuring SFTP backups in this scenario, nor is an OPERATOR role sufficient for performing backup configuration tasks.

Correct : D

In a stretched vSAN cluster within a VMware Cloud Foundation (VCF) VI Workload Domain, the vSAN Witness appliance serves as a quorum mechanism. It is deployed as a third site to help the cluster determine which site should continue operating in the event of a network partition or site failure. This third 'witness' site does not store actual data but maintains metadata to track the cluster's status, ensuring high availability and preventing data loss by enabling failover between the two primary data sites.

The vSAN Witness does not store a third copy of VM data, provide additional storage, or act as a network connection during outages.

Correct : C

For VMware Cloud Foundation (VCF) 5.0 in a consolidated architecture model, vSAN Express Storage Architecture (ESA) is the recommended and supported principal storage option. vSAN ESA is optimized for performance and efficiency and is designed to work seamlessly within the consolidated model, where both management and workload domains share the same infrastructure.

Correct : D

In vSAN storage, the Failures to Tolerate (FTT) parameter in the storage policy determines the number of host or disk failures a virtual machine can withstand without data loss. Setting FTT = 2 ensures that the VM is protected even in the event of two simultaneous host failures by creating additional data replicas to meet this level of redundancy.

Correct : A

To support two host failures with vSAN Erasure Coding, specifically using RAID-6 (4+2) Erasure Coding, a minimum of 6 hosts is required. RAID-6 allows data to tolerate two simultaneous failures by distributing parity data across the hosts, which provides fault tolerance with a lower storage overhead compared to mirroring.

3 hosts or 4 hosts would not support RAID-6 and would be limited to RAID-1 (mirroring) configurations. 5 hosts are also inadequate because RAID-6 requires at least 6 hosts to achieve the 4+2 configuration.
