How we research and review these pages
Which port is used by Smart Meter?
Correct Answer:
B
Explanation
Smart Meter is a Cohesity component that communicates over HTTPS, which uses port 443. This is a standard secure communication port used by the appliance for management and monitoring interfaces. Questions about port assignments fall under configuration knowledge, which is essential for setting up NetBackup appliances correctly.
Which of the following steps are involved in configuring cloud storage in NetBackup?
Correct Answer:
A
Explanation
( To configure cloud storage in NetBackup, you need to define cloud storage credentials and configure a cloud storage server, which involves specifying the cloud storage endpoint, access key, and secret key, among other parameters.)
What is the purpose of the Staging Schedule option in the Change Storage Units dialog?
Correct Answer:
A
Explanation
( The Staging Schedule option in the Change Storage Units dialog allows you to define a schedule for moving backup data from the staging area to secondary storage, enabling you to optimize your backup storage utilization and reduce storage costs.)
An administrator creates a Storage Lifecycle Policy (SLP) to take advantage of optimized duplication. The backup and subsequent duplication jobs launch as configured in the SLP.
What may cause the secondary duplication job to run as non-optimized?
Correct Answer:
A
Explanation
Optimized duplication in NetBackup requires specific media server configuration to work properly. The media servers involved must be set up as Fibre Transport media servers to enable optimized duplication. Without this configuration, the secondary duplication job will fall back to running as non-optimized, even though the SLP is configured correctly. This reflects knowledge needed during the storage configuration phase.
An administrator wants to look at configuration information: status, drivers loaded, port and device information and connections to remote appliances for all Fibre Channel HBAs installed on an appliance.
Which NetBackup Appliance Shell Menu (CLISH) command should the administrator use to display the information?
Correct Answer:
C
Explanation
The CLISH command path Manage > FibreChannel > Show is used to display comprehensive Fibre Channel HBA information including configuration status, loaded drivers, port details, device information, and connections to remote appliances. Administrators need this command to verify proper Fibre Channel hardware setup and connectivity. Knowing which CLISH commands retrieve specific appliance configuration data is part of initial NetBackup configuration and setup.

COH-285 Exam FAQ
Common questions about the exam itself
What hands-on experience should I have before taking the COH-285 exam?
Cohesity recommends 6 to 9 months of hands-on experience working with NetBackup systems and performing backup and recovery operations. While no prior certification is required, familiarity with NetBackup administration, policy configuration, and job management is essential for success on this exam.
How hard is the COH-285 exam compared to associate-level Cohesity certifications?
COH-285 is positioned as a professional-level certification requiring intermediate to advanced knowledge of NetBackup architecture and operations. It assumes deeper technical expertise than associate-level exams and emphasizes practical troubleshooting and performance tuning alongside configuration skills.
Which objective area on COH-285 requires the most preparation time?
Monitor and Maintain NetBackup accounts for 36 percent of the exam and covers a broad range of operational tasks. Many candidates find job management, storage monitoring, and security administration challenging. Focus on understanding the NetBackup Administration Console thoroughly and practice with real job logs and reports.
How long should I realistically prepare for COH-285?
If you already have 6 to 9 months of NetBackup experience, plan for 4 to 6 weeks of focused study using Cohesity's official training materials and practice questions. Without hands-on experience, you should plan for 8 to 12 weeks and prioritize lab work with actual NetBackup appliances.
