Cisco 300-610 Certification Sample Questions and Answers

Cisco 300-610 sample questions for Cisco Certified Specialist - Data Center Design preparationThe Cisco 300-610 Certification Sample Questions on this page help you become familiar with the question style and knowledge areas of the Cisco Certified Specialist - Data Center Design (DCID) exam. Each question is written to reflect the syllabus topics and the level of understanding the certification expects, so you can see how theoretical concepts are tested in practice. Working through them lets you check your understanding, identify topics that need further study, and get comfortable interpreting certification-style questions before you sit the official exam.

These free sample questions are a useful starting point, but they cover only a small part of complete preparation. Reading the documentation, completing recommended training, and gaining hands-on experience build the underlying knowledge required for the certification. Structured practice then shows how well you can recall and apply that knowledge to exam-oriented questions, and reviewing the explanation for each answer helps you understand why a particular option is correct. As your preparation progresses, timed practice helps you develop pacing, sharpen question interpretation, and make confident decisions under exam conditions. Combining these approaches over several study sessions gives you a realistic measure of your readiness ahead of the Cisco Certified Specialist - Data Center Design exam.

Premium Practice is built for complete exam preparation: it gives you the full practice question set for your certification, full-length and mini timed sessions, unlimited attempts for 60 days, and a saved attempt history so you can review progress over time. In short, the demo shows you how the platform works, while Premium supports repeated self-assessment throughout your preparation.

Cisco 300-610 (DCID) Sample Questions:

01. In a VXLAN BGP EVPN design the team must place the tunnel endpoints that encapsulate and decapsulate overlay traffic.
Where should the VTEP function be placed in this fabric?
a) On the APIC controller cluster that drives fabric encapsulation policy
b) On the leaf switches where fabric endpoints attach for encapsulation
c) On the external WAN edge routers doing the fabric encapsulation
d) On the spine switches acting as the encapsulating fabric core
 
02. A collapsed-core SAN has run out of ports, and the team is adding two rows of new host cabinets while the arrays remain centralized.
What is the most appropriate evolution of the topology?
a) Replace the fabric with iSCSI over the existing site LAN
b) Jump straight to edge-core-edge with dedicated storage edges too
c) Add a second collapsed core and trunk the two together
d) Migrate to core-edge by moving hosts onto new edge switches
 
03. Two MDS switches carry several VSANs and are joined by one ISL. The design must let that link carry traffic for all of the VSANs while keeping them isolated.
Which ISL design achieves this?
a) An enhanced ISL trunk on TE ports carrying all VSANs
b) A separate physical ISL dedicated to each VSAN link
c) Merging the VSANs so a plain ISL carries one domain
d) A host port-channel from each server to both switches
 
04. A multi-site design must decide between an active/active and an active/standby model for the interconnected data centers.
Which statement best captures the trade-off an active/active DCI introduces?
a) It removes any need to isolate failure domains between the sites
b) It eliminates the need for ingress path optimization between sites
c) It always lowers the total bandwidth the DCI must carry
d) It improves utilization and failover but widens the shared fault surface
 
05. UCS uplinks to the LAN must sustain a target aggregate bandwidth and survive the loss of any single upstream switch or link.
Which uplink design best meets both goals?
a) A port-channel from each fabric interconnect spread across two upstream switches as a vPC
b) Several separate uplinks left unbundled with no port-channel at all
c) Two uplinks bundled together to the same single upstream switch
d) A single high-bandwidth uplink from each fabric interconnect to one switch
 
06. A retailer runs an application active in two data centers. Virtual machines migrate between sites keeping their IP addresses, and the business needs external clients to always reach the site currently running each VM without back-hauling across the DCI. Layer 2 is already extended for the move itself.
Which addition most directly meets the inbound-steering requirement?
a) Widening the OTV extended-subnet footprint to more site VLANs
b) Higher HSRP priority on one site's inbound gateway
c) LISP mapping each endpoint to its current site for inbound steering
d) A larger stretched spanning-tree domain across both client sites
 
07. A virtualization platform needs shared storage for many hosts. The workload is latency-sensitive block I/O, the team already operates a lossless-capable data center Ethernet fabric, and leadership wants to avoid standing up and staffing a parallel Fibre Channel SAN.
Which access design best fits all three constraints?
a) Converge block storage onto the lossless Ethernet fabric using FCoE
b) Route block traffic over a best-effort IP path between hosts
c) Build a dedicated parallel Fibre Channel fabric for the platform
d) Deploy NAS file shares to every virtualization platform host
 
08. A cloud provider is designing a multi-tenant VXLAN BGP EVPN fabric. Requirements include per-tenant routing isolation, seamless VM mobility across racks, and a backbone that stays simple IP transit.
Which design decisions align with these requirements?
(Choose three.)
a) Bridge and stretch one flat tenant L2 domain across racks
b) Centralize all inter-tenant routing onto one gateway pair
c) Keep the spine as pure tenant IP transit without VTEP
d) Enable a distributed anycast gateway on every tenant leaf
e) Bind each tenant to its own VRF and L3 VNI
 
09. Two data centers are several hundred kilometers apart with no owned fiber. The enterprise needs routed reachability between many tenant VRFs across the sites and prefers to offload transport to a carrier rather than light and operate its own optical path.
Which interconnect design best fits these constraints?
a) Back-to-back vPC across the wide-area path between sites
b) A carrier MPLS service carrying per-tenant Layer 3 reachability
c) DWDM over enterprise-owned dark fiber between the two sites
d) A single stretched Layer 2 broadcast domain across the carrier
 
10. An operations team wants to shrink the blast radius of spanning-tree events in a data center that still has some classic L2 segments. The design goal is to keep the spanning-tree domain as small as possible.
Which design choice best supports minimizing the spanning-tree domain?
a) Stretch every VLAN across all switches for maximum L2 flexibility
b) Raise spanning-tree timers to slow domain reconvergence
c) Route at the leaf to shrink each L2 spanning-tree domain
d) Add more inter-switch trunks to widen the L2 mesh domain
