Cohesity Data Protection Associate Certification Examination
==============================
SECTION 1: Cohesity Platform Architecture and Fundamentals
Question 1
Which Cohesity component serves as the unified web-based management interface for
administering multiple Cohesity clusters from a single pane of glass?
A. Cohesity Cluster
B. Cohesity Helios
C. Cohesity DataPlatform
D. Cohesity SmartFiles
Correct Answer: B
Rationale: Cohesity Helios is the SaaS-based unified management platform that
provides centralized visibility, monitoring, and management of multiple Cohesity
clusters across on-premises, cloud, and edge environments. It enables global search,
capacity forecasting, and policy-based management. The Cluster is the local
,hardware/software instance, DataPlatform is the underlying software architecture, and
SmartFiles is a file services solution.
Question 2
In a Cohesity cluster, what is the minimum number of nodes required to form a cluster
that supports data protection operations with fault tolerance?
A. 1 node
B. 2 nodes
C. 3 nodes
D. 5 nodes
Correct Answer: C
Rationale: A Cohesity cluster requires a minimum of 3 nodes to form a cluster with fault
tolerance and support data protection operations. This minimum node count ensures
that the distributed file system can maintain data availability and integrity using
replication and erasure coding. A single node cannot form a cluster, and 2 nodes do not
provide adequate fault tolerance for the distributed architecture.
Question 3
,Which Cohesity storage efficiency technology eliminates redundant data blocks across
all workloads stored on the cluster?
A. Compression
B. Deduplication
C. Erasure coding
D. Thin provisioning
Correct Answer: B
Rationale: Deduplication is the process of eliminating redundant data blocks across all
workloads stored on the Cohesity cluster, storing only unique data blocks. This occurs
at the global level across the entire cluster, not just within individual protection jobs.
Compression reduces data size by encoding information using fewer bits. Erasure
coding provides data protection against node failures. Thin provisioning allocates
storage on demand rather than upfront.
Question 4
A Cohesity cluster uses erasure coding with a 2-of-4 configuration. What does this
configuration indicate about fault tolerance?
A. The cluster can tolerate the failure of 1 node without data loss
B. The cluster can tolerate the failure of 2 nodes without data loss
C. The cluster requires 4 nodes minimum but provides no fault tolerance
D. The cluster can tolerate the failure of 3 nodes without data loss
, Correct Answer: B
Rationale: A 2-of-4 erasure coding configuration means that data is striped across 4
nodes with 2 parity fragments, allowing the cluster to tolerate the failure of up to 2
nodes without data loss. The "2-of-4" indicates that 2 data fragments plus 2 parity
fragments are distributed across 4 nodes, providing N+2 fault tolerance. This is a
common configuration for Cohesity clusters requiring higher resiliency.
Question 5
Which Cohesity service is responsible for managing the distributed file system and
ensuring data consistency across cluster nodes?
A. Iris
B. Magneto
C. Yoda
D. Groot
Correct Answer: A
Rationale: Iris is the Cohesity service responsible for managing the distributed file
system, metadata operations, and ensuring data consistency across cluster nodes. It
handles the core storage layer functions. Magneto is the data protection service that
manages backup and recovery operations. Yoda is the replication service. Groot is the
indexing and search service. Understanding these core services is essential for
Cohesity administration.
