1.
During initial cluster deployment, a customer reports nodes failing to join the cluster. What is the first
step?
A) Verify network connectivity and proper IP configuration
B) Reinstall the OS on all nodes
, Page 2 of 142
C) Ignore errors and continue deployment
D) Immediately contact Cohesity support
Answer: A) Verify network connectivity and proper IP configuration
Rationale: Node failures are commonly caused by misconfigured IP addresses, DNS, or VLAN issues.
Checking network settings first avoids unnecessary reinstallations.
2.
A new cluster is planned for a medium-sized environment. Which factor is most important for proper
sizing?
A) Storage requirements, number of VMs, and backup retention policies
B) Color of server racks
C) Physical location of the data center cafeteria
D) Employee preferences
Answer: A) Storage requirements, number of VMs, and backup retention policies
Rationale: Cluster sizing depends on storage, workload, and retention to ensure capacity and
performance.

3.
A Cohesity node is unreachable after adding it to the cluster. What should the installer check first?
A) Network connectivity, VLAN assignment, and firewall rules
B) Cluster dashboard color scheme
C) User interface language settings
D) Node warranty documentation
Answer: A) Network connectivity, VLAN assignment, and firewall rules
Rationale: Nodes rely on network connectivity for cluster communication; misconfigured VLANs or
firewalls often block node registration.
4.
A customer wants to enable encryption for all backups. Which option is recommended?
A) Enable at-rest encryption for the cluster and in-transit encryption for network traffic
B) Use password-protected ZIP files
, Page 4 of 142
C) Disable all security features
D) Only encrypt desktop files
Answer: A) Enable at-rest encryption for the cluster and in-transit encryption for network traffic
Rationale: Cohesity supports full data encryption both at-rest and during transit to meet security
compliance standards.
5.
During a protection job setup, a VM is missing from the job. What is the best approach?
A) Verify the VM is powered on and visible to the Cohesity cluster
B) Delete the VM from vCenter
C) Ignore the VM and continue
D) Reinstall the cluster
Answer: A) Verify the VM is powered on and visible to the Cohesity cluster
Rationale: Missing VMs are often due to vSphere visibility or permissions; verifying connectivity resolves
the issue.
