CDCS CDCS Capacity Planning & Lifecycle Management 2

Question 1

What is the typical end-of-life (EOL) refresh cycle for enterprise servers in most data center lifecycle management policies?

Accepted Answer

3–5 years

Answer

1–2 years

Answer

7–10 years

Answer

10–15 years

Question 2

In capacity planning, what does a 'headroom' analysis determine?

Accepted Answer

The remaining available power, cooling, or space capacity before reaching design limits

Answer

The physical height remaining in a rack above installed equipment

Answer

The number of spare patch cables held in inventory

Answer

The buffer time built into a project deployment schedule

Question 3

Which document formally authorizes and tracks the planned installation or decommissioning of equipment in a data center?

Accepted Answer

Move/Add/Change (MAC) order or work order

Answer

Service level agreement (SLA)

Answer

Network topology diagram

Answer

Business continuity plan (BCP)

Question 4

What is 'stranded power' risk that arises from using nameplate power ratings during capacity planning?

Accepted Answer

Capacity is over-allocated based on maximum rated draw instead of actual measured consumption, leaving real capacity unused

Answer

Generators allocate too little fuel for extended runtime

Answer

UPS batteries degrade faster when loads are below nameplate ratings

Answer

Power strips exceed amperage limits when all nameplate loads are active simultaneously

Question 5

What tool or method is used to measure the actual power draw of IT equipment during a data center capacity audit?

Accepted Answer

IPMI/BMC power readings or inline current transducers (CTs) on PDU circuits

Answer

Nameplate label review

Answer

SNMP interface counters

Answer

Thermal imaging cameras

Question 6

What is the purpose of a data center decommissioning checklist when retiring legacy hardware?

Accepted Answer

To ensure data sanitization, asset tracking, safe power-down, cabling removal, and proper disposal or resale of equipment

Answer

To document the planned physical layout for new equipment replacing the retired gear

Answer

To schedule downtime windows for planned maintenance

Answer

To record server BIOS configurations before hardware replacement
