Refer to the exhibit.
Which trusted infrastructure component is missing and represented by the area labeled `A`?
In the exhibit, the area labeled 'A' is outside the Trust Authority Cluster, which suggests it represents an external component. Given the options, the Key Management Server (KMS) is the external entity responsible for managing encryption keys and is commonly associated with key providers in such architectures. Therefore, the component missing and represented by 'A' in the exhibit is the Key Management Server.
What are two supported ESXi boot options? (Choose two.)
ESXi supports booting from both iSCSI (Internet Small Computer System Interface) and SAN (Storage Area Network). These options provide the necessary storage protocols and infrastructure to allow an ESXi host to boot successfully, making them supported boot options. NFS, vSAN, and vSphere Virtual Volumes are not typically used for booting ESXi hosts; they serve different purposes in the VMware ecosystem.
An administrator receives an escalation to investigate a low disk space alarm on a datastore. The administrator discovers that a snapshot has been accidentally taken on a production, write-intensive database server. The snapshot has grown to nearly 1 TB in size in less than an hour and continues growing every second.
Which behavior should the administrator expect while deleting the snapshot?
When deleting a snapshot on a production, write-intensive database server, especially one that has grown significantly, the ESXi host will commit the snapshot delta disk into the base disk. This process involves significant data merging and synchronization, leading to potential long stun times if there is ongoing high write activity, as the system needs to ensure data integrity and consistency during the snapshot deletion. This extensive merging operation can notably impact the performance of the virtual machine due to the size and continuous growth of the snapshot.
Which two storage technologies can an administrator use to deploy the Virtual Machine File System (VMFS)? (Choose two.)
The Virtual Machine File System (VMFS) can be deployed on block-based storage technologies, which are necessary to support VMFS. Fibre Channel storage and iSCSI storage are both block-based storage technologies and are therefore appropriate for deploying VMFS. Other options, such as vSAN storage, Virtual Volumes storage, and NFS storage, do not meet these requirements as they are either object-based or file-based.
An administrator runs a two-node vSphere cluster, which contains two domain controller virtual machines (VMs). The administrator wants to ensure that VMs run on separate hosts without interfering with normal maintenance operations.
How should the administrator configure Distributed Resource Scheduler (DRS)?
To ensure that the two domain controller virtual machines run on separate hosts, the administrator should create a 'Virtual Machines to Virtual Machines' anti-affinity rule. This rule specifies that the selected virtual machines should not run on the same host, achieving the goal of separation. This configuration allows normal maintenance operations to be carried out because the VMs can still move between hosts as needed without being strictly forced to stay on one or constrained by a host-related rule.
