1Which Cisco data center function is performed by a VXLAN Tunnel Endpoint (VTEP)?

A.It translates Fibre Channel frames into iSCSI commands

B.It encapsulates and decapsulates VXLAN traffic at the edge of the overlay

C.It elects the OSPF designated router on a transit segment

D.It provides DHCP addresses to endpoint groups

Explanation: A VTEP sits at the edge of a VXLAN fabric and adds or removes the VXLAN header as traffic enters or leaves the overlay. That is how local Layer 2 frames can traverse an IP underlay between remote switches.

2What problem does vPC primarily solve in a Cisco Nexus data center design?

A.It allows hosts to use two switches as if they were one logical port-channel partner

B.It replaces the need for VLANs in a Layer 2 network

C.It converts multicast traffic into unicast traffic

D.It encrypts east-west traffic between leaf switches

Explanation: vPC lets a device form one port channel to two separate Nexus switches, improving link utilization and resiliency. It avoids the traditional spanning-tree behavior of blocking one of the redundant uplinks.

3In a VXLAN EVPN fabric, what is the main purpose of an anycast gateway?

A.To assign a unique default gateway IP to every leaf switch

B.To provide one default gateway MAC and IP presence across multiple leafs for the same subnet

C.To load balance OSPF LSAs between spines

D.To replace the need for BGP EVPN route exchange

Explanation: An anycast gateway gives endpoints the same default gateway presence everywhere in the fabric. This improves mobility and reduces tromboning because hosts can keep the same gateway when they move between leafs.

4What does a tenant represent in Cisco ACI?

A.A physical spine switch dedicated to one customer

B.A logical administrative boundary containing policies, VRFs, bridge domains, and application profiles

C.A backup copy of the APIC configuration database

D.A dedicated Fibre Channel fabric for storage traffic

Explanation: A tenant is a logical container for policy objects and segmentation constructs in ACI. It is used to separate applications, business units, or customers within the same physical fabric.

5An OSPF adjacency between two leaf switches does not come up in the underlay. Which mismatch is the most likely direct cause?

A.The switches have different system hostnames

B.The interfaces use different OSPF area IDs

C.The loopback interfaces use /32 masks

D.The devices are configured with different NTP servers

Explanation: OSPF neighbors must agree on key adjacency parameters, including the area ID on the interface. If the area IDs differ, the devices will not form a full OSPF adjacency.

6Which identifier maps a Layer 2 segment inside a VXLAN fabric?

A.VNI

B.VSAN

C.ETag

D.RLOC

Explanation: The VXLAN Network Identifier, or VNI, identifies the overlay segment carried across the IP fabric. It plays a role similar to a VLAN ID, but with a much larger address space.

7What is an endpoint group (EPG) in Cisco ACI used for?

A.Grouping endpoints that should share the same policy treatment

B.Designating which APIC controller is the cluster leader

C.Advertising loopback routes into the underlay

D.Converting FC traffic to Ethernet traffic

Explanation: An EPG is a policy construct that groups endpoints with similar connectivity and security requirements. Contracts are typically applied between EPGs to control how those groups communicate.

8In a leaf-spine topology, which device type should generally connect directly to servers?

A.Spine switches

B.Leaf switches

C.Route reflectors only

D.Storage processors only

Explanation: Leaf switches are the access layer for endpoints in a leaf-spine design. Spine switches provide the high-speed interconnect between leafs and are not usually used for direct host attachment.

9Which BGP EVPN route type is commonly used to advertise MAC and IP reachability for endpoints?

A.Type 1

B.Type 2

C.Type 3

D.Type 5

Explanation: Type 2 EVPN routes carry MAC and optional IP information for endpoints. They let VTEPs learn remote host reachability through the control plane instead of relying only on flooding.

10Why is a leaf-spine fabric typically preferred over a traditional three-tier design for east-west traffic?

A.It forces all server traffic through a single aggregation switch

B.It creates a predictable low-hop path between any two leafs

C.It removes the need for IP routing in the data center

D.It prevents the use of overlays such as VXLAN

Explanation: A leaf-spine topology gives any leaf-to-leaf flow a consistent path length through the spine layer. That predictable latency and scale-out behavior make it well suited for modern east-west application traffic.

CCNP Data Center Study Tips from Top Performers

1Weight your study plan to the blueprint: Network and Compute deserve the most time because together they represent half of the DCCOR core exam.

2Lab NX-OS, ACI, and UCS concepts instead of memorizing definitions only. Service profiles, vPC behavior, VLAN and VXLAN design, and SAN workflows are easier to retain when you have configured them.

3Do not neglect storage networking. VSANs, zoning, NPIV and NPV, and FCoE still account for a meaningful portion of the blueprint and are frequent weak spots for enterprise network engineers.

4Build API fluency with Cisco-style workflows: parse JSON, understand REST methods, and practice basic Python and Ansible tasks against infrastructure objects.

5Treat security as data center policy enforcement, not generic security trivia. Focus on RBAC, segmentation, contracts, device hardening, and secure management access.

6Use mixed practice sets after each domain block so you can switch between network, compute, SAN, and automation thinking without losing speed.

7Plan the concentration exam early. If your follow-on path will be DCIT, DCSAN, DCACI, DCNAUTO, or DCAI, start capturing overlap while studying DCCOR.

Frequently Asked Questions

What do you need to earn CCNP Data Center?

Cisco requires two exams: the 350-601 DCCOR core exam plus one approved concentration exam. As of March 11, 2026, Cisco's current Data Center exam listings include concentration options such as DCID, DCIT, DCACI, DCSAN, DCNAUTO, and the newer DCAI path. Your certification becomes active only after both requirements are complete.

How many questions are on the CCNP Data Center exam?

Cisco does not publish a fixed question count for its written professional exams, including DCCOR 350-601. The official details Cisco does publish are the 120-minute appointment length, language availability, and pass/fail scoring. For planning purposes, many candidates prepare as if the core exam will be roughly around 100 questions, but that figure is not official.

What is the passing score for CCNP Data Center?

Cisco does not publish a fixed passing score for the DCCOR written exam. After you test, Cisco provides a score report and pass/fail result, but the exact cutoff is not published in advance because exam forms can vary. The safest approach is to study to the full blueprint rather than aiming for a rumored score target.

What topics matter most on DCCOR 350-601?

The current DCCOR v1.2 blueprint places the most weight on Network (25%) and Compute (25%). Storage Network accounts for 20%, while Automation and AI plus Security are 15% each. In practice, that means you should be strong on NX-OS and ACI networking, UCS and virtualization, FC and FCoE SAN operations, and then round out your prep with APIs, automation workflows, and security controls.

What changed for CCNP Data Center in 2026?

The main 2026 change on the certification track is the new 300-640 DCAI concentration exam, which Cisco lists with a first test date of February 9, 2026. I did not find a newer 2026 DCCOR core blueprint replacing v1.2, so the latest official core-domain outline still appears to be the current standard. Cisco's broader exam policies, including the 5-day retake wait for written exams, remain in effect.

How long should you study for CCNP Data Center?

Most candidates need several months of focused prep, especially if they are building both conceptual knowledge and hands-on practice at the same time. A practical target is 10 to 18 weeks for the core exam, with extra time if you are still learning ACI, UCS service profiles, or SAN fundamentals from scratch. Lab work matters because DCCOR expects operational understanding, not just terminology recall.
