Once the SOP is updated, ensure that all team members are informed and trained on the new procedures.
How do you ensure compliance with data security procedures during hardware decommissioning?
Follow Established Policies
Adhere strictly to the company’s data security and hardware disposal policies throughout the process.
Data Backup and Verification
Confirm that all important data has been securely backed up and verified before decommissioning.
Secure Data Erasure
Use approved methods to securely erase all data from storage devices, such as data wiping software or degaussing, ensuring data cannot be recovered.
For highly sensitive data, consider physical destruction of drives (e.g., shredding).
Document the Process
Maintain detailed records of the decommissioning steps, including serial numbers, data destruction certificates, and personnel involved.
Chain of Custody
Ensure hardware is tracked carefully from removal through final disposal or recycling to prevent unauthorized access.
Use Certified Disposal Vendors
When disposing of hardware, use certified e-waste recyclers who comply with data security and environmental regulations.
Audit and Verification
Conduct audits or request certificates of data destruction to verify compliance.
Train Staff
Ensure all personnel involved are trained on data security requirements and understand their responsibilities during decommissioning.
What process would you follow for handling ESD (electrostatic discharge) sensitive components?
Prepare an ESD-Safe Workspace
Work at a designated ESD-protected area equipped with an anti-static mat connected to ground.
Ensure the environment has controlled humidity to reduce static buildup.
Wear Proper ESD Protection
Always wear a wrist strap connected to ground to dissipate static electricity safely.
Use ESD-safe gloves or finger cots if required.
Use ESD-Safe Tools and Packaging
Handle components with ESD-safe tools (e.g., tweezers, screwdrivers).
Store and transport components in anti-static bags or containers.
Minimize Handling
Touch components only by their edges or designated handling areas.
Avoid touching pins, connectors, or circuitry directly.
Discharge Yourself Before Handling
If you don’t have a wrist strap, touch a grounded metal object to discharge static buildup before touching components.
Avoid Wearing Static-Prone Clothing
Avoid clothing made of wool or synthetic fibers that generate static.
Handle One Component at a Time
Reduces risk of accidental damage and ensures focused attention.
Follow Manufacturer Guidelines
Always consult specific ESD handling instructions provided by the component or device manufacturer.
How do you document hardware changes in asset management systems?
Identify the Asset
Locate the hardware asset using its unique identifier, such as an asset tag or serial number.
Record Change Details
Document the specific change being made (e.g., hardware upgrade, replacement, relocation).
Include relevant information such as date, time, and reason for the change.
Update Asset Information
Modify asset records to reflect new details, like updated hardware specifications, new location, or status (active, retired, in repair).
Attach any related documentation such as purchase orders, warranty info, or installation reports.
Assign Responsibility
Log the name of the person or team performing the change to maintain accountability.
Use Standardized Forms or Templates
Follow company-approved forms or digital workflows to ensure consistency in data entry.
Link Related Assets
If the change affects other equipment (e.g., new parts linked to a server), update relationships in the system.
Review and Approve Changes
Have changes reviewed and approved by supervisors or asset managers when required.
Maintain Audit Trail
Ensure the system tracks all modifications with timestamps for auditing and future reference.
How do you escalate a critical incident you can’t resolve on your own?
Assess and Document the Issue
Gather all relevant information: symptoms, error messages, steps already taken, and impact on operations.
Document this clearly to provide a concise summary.
Notify Immediate Supervisor or Team Lead
Inform your direct manager or designated point of contact promptly, sharing your findings and attempts to resolve the issue.
Follow Escalation Procedures
Use the organization’s defined escalation path—this may involve contacting senior engineers, specialized support teams, or vendor support.
Adhere to any priority or severity guidelines.
Provide Clear Communication
Explain the situation, urgency, and potential business impact.
Share your documentation to help others understand and take over quickly.
Stay Available and Supportive

Update Stakeholders
Keep relevant stakeholders informed of progress and estimated resolution times.
Learn and Document for Future
After resolution, review the incident to identify improvements in response or escalation procedures.
Explain your understanding of SLAs (Service Level Agreements) in a data center.
SLAs are formal contracts between a service provider (like a data center) and its customers that define the expected level of service. They set clear expectations and responsibilities for both parties.
Uptime Guarantee
Specifies the percentage of time the data center services (power, cooling, network) will be available.
Example: A 99.99% uptime means the service can only be down for about 52 minutes per year.
