Netapp NS0-185 Exam With Confidence Using Practice Dumps

This question tests installation cabling constraints and supported cabling media for SAS connectivity. The key issue is distance: the customer wants to use20-meter copper SAS cablesbetween a controller and a shelf that are installed in separate rows.

NetApp hardware cabling guidance indicates that when long distance SAS connectivity is required, the supported approach is to useSAS optical cabling(for applicable platforms and shelf/IOM combinations). The ONTAP hardware systems documentation describes “mini-SAS HD SAS optical cable rules,” noting that optical AOC SAS cables are available in lengths up to50 metersfor controller-to-stack and shelf-to-shelf connections in supported configurations. This highlights a critical installation principle: long SAS runs are addressed withoptical, not copper.

The documentation also establishes that SAS cabling within a stack must be consistent (all copper or all optical) and that mixed approaches have specific constraints. While the excerpt emphasizes optical rules (because optical is the mechanism for long distance), it implicitly reinforces that copper has practical distance limitations and is not the long-distance solution.

Therefore, if the customer insists on copper SAS, the correct guidance is thatthe controller and disk shelf must be closer togetherto remain within supported copper SAS distance limits and to ensure signal integrity and supported operation. Option B is incorrect because simply “obtaining” 20-meter copper SAS cables does not make the configuration supported. Option D is incorrect because Ethernet adapters do not replace SAS for shelf connectivity. Option A is nonsensical in this context because SAS shelf connectivity cannot be replaced by a “wireless adapter” as a supported installation practice.

Thus, the correct answer isC: if copper cables are to be used, the devices must be closer together; otherwise the supported solution is to use a supported SAS optical approach.

Cluster peering enables data replication and disaster recovery features such as SnapMirror and SnapVault. LIF configuration for cluster peering follows specific ONTAP SAN concepts.

Each cluster participating in a peer relationship must haveat least one intercluster LIF per node. This ensures redundancy and allows ONTAP to balance replication traffic across nodes.

Additionally,intercluster LIFs must use the default intercluster service policy, which defines the permitted traffic types and security rules required for peering operations.

An MTU of 9000 is recommended but not mandatory. Dedicated broadcast domains or IPspaces are optional and depend on network design.

Therefore, the correct answers areB and D.

The cluster ping-cluster command is specifically designed to testinter-node cluster network connectivity, includinglatency, packet loss, and throughputbetween cluster nodes. This command generates synthetic traffic over the cluster interconnect and measures performance characteristics that directly affect cluster health and stability.

The command is commonly used duringpost-installation validation, cluster expansion, and troubleshooting scenarios involving cluster network performance. It provides insight into whether the cluster interconnect is operating within expected parameters.

Other commands listed do not provide this functionality. QoS workload statistics focus on application-level performance, network test-path validates reachability for LIF failover paths, and statistics node show reports internal node counters rather than inter-node network performance.

Therefore, the correct answer isB.
