VMware vSphere Foundation 9.0 Administrator Free Sample Questions

vSphere Virtual Volumes (vVols) is the integration and management framework that virtualizes SAN/NAS arrays, enabling a more efficient operational model that is optimized for virtualized environments. It moves management from the LUN level to the VM level using Storage Policy Based Management (SPBM).

vSphere 9.0 enforces the use of TLS 1.2 or higher for all encrypted management traffic. Older protocols like SSLv3 and TLS 1.0/1.1 are disabled by default to comply with modern security standards and regulatory requirements.

VMware vSphere Foundation (VVF) has transitioned to a subscription-based model licensed on a 'per Core' basis. There is a minimum requirement of 16 cores per CPU for licensing purposes, regardless of the actual physical core count if it is lower.

ESXi is a bare-metal (Type 1) hypervisor, meaning it installs directly on the physical hardware. This minimizes overhead and improves performance and security compared to Type 2 hypervisors (hosted) which run as an application on top of an OS.

FC-NVMe (Fibre Channel over NVMe) allows NVMe command sets to be encapsulated within Fibre Channel frames. This enables organizations to leverage high-performance NVMe storage arrays while utilizing their existing Fibre Channel switching infrastructure.

The Content Library is a container object that stores and manages content such as VM templates, vApp templates, and ISO images. It can be published and subscribed to by other vCenter Servers, ensuring consistency of images across different sites.

NIC Teaming (also known as bonding or link aggregation) allows multiple physical NICs on an ESXi host to be grouped together. This provides aggregated bandwidth and redundancy; if one link fails, traffic fails over to the remaining active links.

vSAN ESA introduces a single-tier architecture where all NVMe devices contribute to both capacity and performance. It eliminates the disk groups concept (cache + capacity tiers) found in OSA, utilizing a new log-structured file system (LFS) for higher performance and efficiency.
