MetroCluster Solution Assessment · Site, power, cabling and hardware prerequisites
Case Study: Global Logistics Corp
Global Logistics Corp is designing a new disaster recovery architecture between their primary data center in Frankfurt and a secondary site in Munich. The physical distance between the sites is 350 kilometers. The business requires a strict zero Recovery Point Objective (RPO) and automatic failover capabilities without human intervention if a complete site failure occurs.
They have a robust existing IP backbone (100GbE) between the sites but no dark fiber or Fibre Channel infrastructure. They plan to use AFF A400 controllers at both sites. They have a third, smaller administrative office in Berlin that can host lightweight management virtual machines.
Based on these requirements and constraints, which MetroCluster architecture and automated switchover mechanism is optimal for this design?

Correct answer: C
The 350km distance and lack of FC infrastructure dictate a MetroCluster IP solution. To achieve fully automatic switchover (AUSO) in a MetroCluster IP environment without human intervention, the ONTAP Mediator must be deployed at a third site (Berlin). MetroCluster FC is limited to 300km natively and they lack FC infrastructure.

MetroCluster Solution Assessment · Configuration components using tools
An implementation engineer has finished racking, cabling, and powering on all components for a new 4-node fabric-attached MetroCluster FC. Before configuring ONTAP, the engineer needs to validate the SAS cabling, ATTO bridge configurations, and FC switch zoning. Which tool should be executed on a local management workstation to perform this pre-configuration validation?
Show answer & explanation
Correct answer: D
NetApp Active IQ Config Advisor is a diagnostic tool used by field engineers to validate cabling, firmware, and configurations before and after deployment. It can connect directly to the devices locally to verify SAS cabling, ATTO bridges, and switch zoning prior to running the ONTAP MetroCluster configuration commands.
- Question 3Beginner
MetroCluster Solution Assessment · Configuration components using tools
You are preparing to deploy a MetroCluster IP solution using Broadcom backend switches. You need to create the specific configuration files that will set up the necessary VLANs, MTU sizes, and port settings on these switches. Which tool provides this capability?
Show answer & explanation
Correct answer: D
The RcfFileGenerator tool is used to generate the Reference Configuration Files (RCFs) for supported backend switches (both FC and IP). These files apply the NetApp-validated port settings, VLANs, and MTU sizes required for MetroCluster.
- Question 4Intermediate
MetroCluster Solution Assessment · Site, power, cabling and hardware prerequisites
A customer is preparing a data center site for a new MetroCluster IP installation. They are reviewing the power redundancy requirements for the backend IP switches. According to NetApp best practices for MetroCluster site prerequisites, how should the power for the redundant backend IP switches be distributed?
Show answer & explanation
Correct answer: C
To ensure maximum availability and prevent a single point of failure, site prerequisites dictate that each backend switch (which has redundant power supplies) must have its power connections distributed across separate, independent power grids or PDUs.
- Question 5Intermediate
MetroCluster Solution Assessment · Configuration components using tools
The NetApp web-based tool that is used to verify compatible combinations of ONTAP versions, disk shelf models, and third-party backend switches prior to a MetroCluster deployment is called the ____________.
Show answer & explanation
Correct answer: D
The Interoperability Matrix Tool (IMT) is the official NetApp resource used to verify the compatibility of software versions, hardware models, and third-party components (like switches) for a valid MetroCluster configuration.
- Question 6Beginner
MetroCluster Concepts · MetroCluster architecture and data protection
In a MetroCluster architecture, ONTAP uses SyncMirror to ensure data is mirrored synchronously across sites. How does SyncMirror utilize plexes to achieve this zero data loss protection?
Show answer & explanation
Correct answer: C
SyncMirror protects data by creating a mirrored aggregate that contains two plexes. One plex is constructed from disks located at the local site (pool0), and the second mirrored plex is constructed from disks located at the remote site (pool1).
