- Question 1Cisco Data Center Administration
What is a Cisco UCS blade server?
Show Answer & Explanation
Correct Answer: BExplanation:UCS B-Series blade servers are compact compute modules that insert into a UCS 5108 chassis (holds 8 half-width or 4 full-width blades). They share chassis power supplies, fans, and connect to Fabric Interconnects via I/O modules (IOMs).
- Question 2Cisco Data Center Maintenance
What is the proper procedure for replacing a failed UCS blade server?
Show Answer & Explanation
Correct Answer: BExplanation:UCS blade replacement: 1) Disassociate the service profile, 2) Decommission the blade, 3) Physically remove (pull blade out), 4) Insert new blade (same slot), 5) Acknowledge/discover in UCS Manager, 6) Associate the service profile — the new blade inherits the identity.
- Question 3Cisco Data Center Physical Infrastructure
How many half-width blade servers can a Cisco UCS 5108 chassis accommodate?
Show Answer & Explanation
Correct Answer: BExplanation:The UCS 5108 chassis has 8 blade slots: supports 8 half-width blades (B200M series) or 4 full-width blades (B480M series). The chassis includes 4 PSU bays (2+2 redundant), 8 fan modules, and 2 IOM slots connecting to Fabric Interconnects.
- Question 4Cisco Data Center Maintenance
How do you check the health of a Cisco UCS blade server?
Show Answer & Explanation
Correct Answer: BExplanation:UCS Manager and CIMC provide comprehensive health monitoring including CPU/memory errors, disk status, fan/temperature alerts, power consumption, and overall fault summary.
- Question 5Cisco Data Center Administration
What is the role of a Cisco UCS Fabric Interconnect (FI)?
Show Answer & Explanation
Correct Answer: BExplanation:UCS Fabric Interconnects (6200/6300/6400/6500 series) are the core of UCS: they provide unified management (UCS Manager/Intersight), Ethernet (LAN), Fibre Channel (SAN), and management connectivity for all connected UCS chassis and rack servers.
- Question 6Cisco Data Center Maintenance
What is the procedure for hot-swapping a power supply in a Cisco Nexus switch?
Show Answer & Explanation
Correct Answer: BExplanation:Hot-swap procedure: 1) Verify the second PSU is active and carrying the load ('show environment power'), 2) Remove the failed PSU, 3) Insert the replacement, 4) Verify new PSU status is OK. Redundant PSUs ensure no service disruption.
- Question 7Cisco Data Center Troubleshooting
How do you identify hardware faults in a Cisco UCS environment?
Show Answer & Explanation
Correct Answer: BExplanation:UCS Manager displays faults in a centralized view: Equipment tab shows hardware faults, categorized by severity. Critical faults require immediate action. Filter by type (server, fabric, chassis) and use fault history for trend analysis.
- Question 8Cisco Data Center Maintenance
What is the recommended approach for upgrading firmware on Cisco UCS servers?
Show Answer & Explanation
Correct Answer: BExplanation:UCS firmware upgrades use UCS Manager or Intersight: download firmware bundle, stage it on FI, create/update host firmware policy, and apply to servers during maintenance. Service profiles ensure consistent firmware across the environment.
- Question 9Cisco Data Center Physical Infrastructure
What is the purpose of a Cisco UCS (Unified Computing System) Fabric Interconnect?
Show Answer & Explanation
Correct Answer: BExplanation:UCS Fabric Interconnects provide network connectivity, management, and LAN/SAN switching for all servers in a UCS domain, serving as the central management point.
- Question 10Cisco Data Center Troubleshooting
A server connected to a Nexus switch via vPC is experiencing intermittent connectivity. Which log should be checked first?
Show Answer & Explanation
Correct Answer: AExplanation:Checking logs filtered for vPC events reveals peer-link flaps, role changes, or member port state changes that could cause intermittent connectivity for hosts using vPC port-channels.
- Question 11Cisco Data Center Troubleshooting
A server in a Cisco UCS chassis shows a discovery failure. What should you check first?
Show Answer & Explanation
Correct Answer: BExplanation:Discovery failures typically stem from physical issues: check that the blade is properly seated, IOM ports are connected to fabric interconnects, and links are active.
- Question 12Cisco Data Center Troubleshooting
How do you troubleshoot a Cisco UCS server that fails to PXE boot?
Show Answer & Explanation
Correct Answer: BExplanation:PXE boot failures require checking: boot policy has PXE first, vNIC is on correct VLAN, DHCP server is reachable and has available IPs, and TFTP/HTTP server is accessible.
- Question 13Data Center Equipment
What is CIMC on Cisco UCS C-Series servers?
Show Answer & Explanation
Correct Answer: BExplanation:CIMC is the BMC on C-Series servers: provides web UI and API for remote management, KVM console access, power on/off/cycle, sensor monitoring, BIOS configuration, and firmware updates — all out-of-band.
Key DC Hardware Concepts for CCTDC
CCTDC DC Hardware Exam Tips
Data Center Hardware questions in CCTDC are typically scenario-based. Focus on service-level decision making aligned to official exam objectives. Priority concepts: ucs, nexus, mds, fabric interconnect, server, blade.
What CCTDC Expects
- Anchor your answer in select the most practical, secure, and scalable answer for the stated scenario.
- DC Hardware scenarios for CCTDC are frequently mapped to Domain 1 (35%), so read the objective carefully before picking controls or architecture.
- Expect multi-service scenarios where DC Hardware interacts with IAM, networking, storage, or observability patterns rather than appearing as an isolated service question.
- When two options are both technically valid, prefer the choice that best aligns with the exam's operational scope (Entry) and managed-service best practices.
High-Value DC Hardware Concepts
- Know the core DC Hardware building blocks cold: ucs, nexus, mds, fabric interconnect.
- Review the edge-case features and limits for server, blade; these details are commonly used to differentiate answer choices.
- Practice service-integration reasoning: how DC Hardware pairs with DC Networking, DC Troubleshooting in real deployment patterns.
- For CCTDC, explain why the chosen DC Hardware design meets reliability, security, and cost expectations better than the alternatives.
Common CCTDC Traps
- Watch for answers that partially solve the requirement but miss operational constraints.
- Questions in Cisco Data Center Equipment often include distractors that look correct for DC Hardware but violate least-privilege, durability, or availability requirements.
- Avoid picking options purely by feature name; validate data path, failure handling, and governance impact before answering.
- If the prompt hints at automation or repeatability, eliminate manual-only operational answers first.
Fast Review Checklist
- Can you compare at least two DC Hardware implementation paths and justify which one best fits the scenario?
- Can you map the chosen answer back to Cisco Data Center Equipment (35%) outcomes for CCTDC?
- Can you explain security and access boundaries for DC Hardware without relying on default-open assumptions?
- Can you describe how DC Hardware integrates with DC Networking and DC Troubleshooting during failure, scaling, and monitoring events?
