NS0-157 Question #148: Real Exam Question with Answer & Explanation

The correct answer is A: Minor the namespace constituent by using an intracluster data protection mirror. An Infinite Volume's namespace constituent is a critical metadata component that maps file paths to their corresponding data constituents. Loss of the namespace constituent would make the entire Infinite Volume inaccessible. To protect it, NetApp supports two mirroring strategies

Question

Which two actions protect an Infinite volume from the loss of a namespace constituent? (Choose two)

Options

AMinor the namespace constituent by using an intracluster data protection mirror
BMirror the namespace constituent by using an Intercluster data protection mirror
CMirror the namespace constituent by using a load-sharing mirror
DMirror the namespace constituent by using a FlexCache mirror

Explanation

An Infinite Volume's namespace constituent is a critical metadata component that maps file paths to their corresponding data constituents. Loss of the namespace constituent would make the entire Infinite Volume inaccessible. To protect it, NetApp supports two mirroring strategies: (A) Intracluster DP mirror - replicates the namespace constituent to another node within the same cluster, protecting against node or disk failure locally; (B) Intercluster DP mirror - replicates the namespace constituent to a node in a remote cluster, protecting against site-level failures. Load-sharing mirrors (C) are used for read-only distribution of data (e.g., SVM root volumes) and do not provide the data protection needed here. FlexCache mirrors (D) are a caching mechanism for improving read performance and are not applicable for namespace constituent protection.
