Which two configuration options can only be enabled on distributed switches? (Choose two.)
Which two configuration options can only be enabled on distributed switches? (Choose two.)
Port Mirroring and NetFlow are features that can only be enabled on distributed switches. Port Mirroring allows the copying of network traffic from a virtual switch port to another port for monitoring and analysis purposes. NetFlow is a network protocol used to collect, aggregate, and record traffic data to monitor network performance and detect issues. These capabilities are exclusive to distributed switches and are not available on standard switches. VLAN IDs, NIC Teaming, and Load Balancing can be configured on both standard and distributed switches.
An administrator needs to migrate a powered off virtual machine to another cluster with no shared storage.
Which option should the administrator select for a successful migration?
When migrating a powered-off virtual machine to another cluster with no shared storage, it is necessary to move both the compute resource and the storage. Without shared storage, the virtual machine's files must be relocated to the storage resources available in the destination cluster, in addition to moving its compute resource. Selecting 'Change both compute resource and storage' ensures that the virtual machine and all its associated data are fully transferred to the new cluster, allowing for a successful migration.
Which two block storage protocols are supported on vSphere? (Choose two.)
SAN (Storage Area Network) and iSCSI (Internet Small Computer System Interface) are two block storage protocols supported on vSphere. SAN is a high-speed network that provides block-level access to storage, typically used in fiber channel networks. iSCSI is a protocol that uses IP-based networks to link data storage facilities, allowing for block-level access over Ethernet. The other options, SMB, NFSv4.1, and NFSv3, are file-level protocols and do not provide block storage, which is essential for vSphere environments.
A vSphere operator discovers a storage problem with the following PDL error message:
Permanently inaccessible device :naa.1234567890 has no more open connections.
What should the operator conclude from this error message?
A Permanently Device Loss (PDL) error message indicating that a device is 'permanently inaccessible' and 'has no more open connections' means that the storage device has encountered a failure and is not expected to become available again. This occurs when the underlying storage system determines that a device is no longer accessible due to a permanent hardware issue. Therefore, the correct conclusion is that the storage device has failed and is not expected to become available.
Which piece of information does vSphere DRS consider when making decisions about which host to place a virtual machine?
vSphere Distributed Resource Scheduler (DRS) is designed to automate the placement and balancing of virtual machines across a cluster. One of the key metrics that DRS considers is the network bandwidth on each host. DRS aims to ensure that the host which receives a new virtual machine has sufficient network resources available, preventing overload and ensuring smooth operation and performance of the machine.
