Explanation
B, C, and E are correct because compression, deduplication, and inline zero detection are three global efficiencies for NetApp Element software. Global efficiencies are data reduction techniques that operate across all volumes in a cluster and minimize redundancy while maximizing system performance. The other options are not global efficiencies for NetAppElement software.

Explanation
iSCSI and FC are two protocols that are supported by E-Series systems. They are both block-based protocols that provide low-latency and high-performance storage access for applications such as databases or virtualization.

Explanation
Cloud Manager is a NetApp service that provides a single API endpoint for requesting storage on private and public cloud locations. Cloud Manager allows you to create and manage working environments, such as Cloud Volumes ONTAP systems or Cloud Volumes Service volumes, across multiple cloud providers.

Explanation
A default gateway is an attribute of a host that is used to route packets to a non-local subnet. A default gateway is the IP address of the router that connects the host to other networks.

Explanation
Cloud Volumes ONTAP is a software-defined storage solution that runs on top of cloud infrastructure and provides advanced data management features for file and block workloads. It allows you to move your application workloads to the public cloud and maintain NetApp ONTAP data efficiencies. A PAYGO subscription lets you pay for the storage resources you consume on an hourly basis, which gives you a flexible payment option as you scale your public cloud footprint12.
