Cohesity Data Protection Associate Exam Questions |
100% Correct Answers with Detailed Rationales
(2026/2027 Edition)
SECTION 1: Cohesity Architecture and Platform Fundamentals
Question 1
Which Cohesity component serves as the distributed file system that aggregates
storage resources across all nodes in a Cohesity cluster?
A. Cohesity SpanFS
B. Cohesity DataPlatform
C. Cohesity Helios
D. Cohesity DataProtect
Correct Answer: A
Rationale: Cohesity SpanFS is the proprietary distributed file system that aggregates
storage resources across all nodes in a Cohesity cluster, providing a unified global
namespace. Option B (DataPlatform) refers to the overall software platform, not the
specific file system. Option C (Helios) is the SaaS-based management and analytics
platform. Option D (DataProtect) is the backup and recovery solution built on top of the
platform.
Question 2
In a Cohesity cluster, what is the minimum number of nodes required to form a
production-ready cluster that supports data protection workloads?
,A. One node
B. Three nodes
C. Five nodes
D. Seven nodes
Correct Answer: B
Rationale: A minimum of three nodes is required to form a production-ready Cohesity
cluster that supports data protection workloads, ensuring quorum and high availability.
Option A is incorrect because a single node does not provide fault tolerance or cluster
functionality. Options C and D exceed the minimum requirement.
Question 3
Which Cohesity hardware series is designed specifically for edge and remote
office/branch office (ROBO) deployments with a compact form factor?
A. Cohesity C4000 Series
B. Cohesity C6000 Series
C. Cohesity C8000 Series
D. Cohesity C9000 Series
Correct Answer: A
Rationale: The Cohesity C4000 Series is designed for edge and ROBO deployments with
a compact form factor. The C6000, C8000, and C9000 Series are progressively larger
platforms designed for medium to large enterprise data centers with higher storage and
compute requirements.
Question 4
What is the role of the Cohesity Metadata Store in the cluster architecture?
A. It stores backup data blocks on disk.
, B. It maintains the mapping between logical objects and their physical storage
locations.
C. It manages network traffic between nodes.
D. It provides the user interface for backup administrators.
Correct Answer: B
Rationale: The Cohesity Metadata Store maintains the mapping between logical objects
(such as files, VMs, and backup jobs) and their physical storage locations across the
cluster. Option A is incorrect because data blocks are stored by SpanFS. Option C is
incorrect because network traffic is managed by the cluster networking layer. Option D
is incorrect because the user interface is provided by the Cohesity UI/API layer.
Question 5
Which of the following best describes the Cohesity "SnapTree" technology?
A. A snapshot replication protocol between clusters
B. A B-tree based data structure that enables infinite snapshots with minimal storage
overhead
C. A network compression algorithm for WAN optimization
D. A hardware acceleration card for deduplication processing
Correct Answer: B
Rationale: Cohesity SnapTree is a B-tree based data structure that enables efficient
snapshot management with minimal storage overhead, allowing for a large number of
snapshots without significant performance degradation. Option A describes replication,
not SnapTree. Option C describes WAN optimization, which is handled by Cohesity's
replication engine. Option D is incorrect because SnapTree is a software technology, not
hardware.
