Cisco Implementing and Operating Cisco Data Center Core Technologies Exam Practice Test

The 350-601 DCCOR practice page concerns data center network and compute operations, with question-bank scenarios involving switching, VLANs, traffic monitoring, congestion, VXLAN, and device management. These concepts support work such as maintaining connectivity, observing traffic behavior, and preparing infrastructure changes.

About the Cisco Implementing and Operating Cisco Data Center Core Technologies Exam

Data center operations require interpreting Layer 2 and Layer 3 behavior and selecting controls that preserve segmentation and availability. Practice scenarios include distinguishing VLAN trunk tagging from inter-VLAN routing, identifying SPAN as an approach to copy selected traffic for monitoring, and recognizing how a VTEP handles VXLAN encapsulation and decapsulation. Other questions exercise operational judgment: inspecting queue-drop counters to investigate congestion, protecting access ports from spanning-tree root changes, and using NTP or SNMP for time synchronization and centralized monitoring. Configuration and maintenance tasks also include establishing an in-band management interface and saving configuration before a software upgrade. Together, these topics call for connecting protocol behavior to the symptom or operational goal rather than relying on command recall alone.

Sample Practice Questions

Review a selection from this exam's published US Practice Tests practice bank.

Question 1

A network administrator needs to copy traffic from selected switch ports to a monitoring tool without placing the tool inline. Which feature is most appropriate?

  1. APort security
  2. BSPAN session
  3. CLink aggregation
  4. DDynamic ARP inspection
Show answerCorrect answer: B

A Switched Port Analyzer (SPAN) session mirrors selected traffic to a monitoring destination, allowing analysis without inserting the monitoring device into the forwarding path.

Question 2

A data center switch must forward traffic between two VLANs while keeping their broadcast domains separate. What device function is required?

  1. ALayer 2 bridging only
  2. BLayer 3 routing between VLAN interfaces
  3. CEthernet flow control
  4. DPort mirroring
Show answerCorrect answer: B

Communication between different IP subnets or VLANs requires a Layer 3 function, commonly provided by switch virtual interfaces (SVIs) on a multilayer switch. Bridging alone forwards within a Layer 2 domain.

Question 3

A server interface supports IEEE 802.1Q tagging, and the switch must deliver one VLAN untagged while carrying other VLANs tagged. Which trunk setting describes the untagged VLAN treatment?

  1. ANative VLAN
  2. BRoot VLAN
  3. CManagement VLAN
  4. DVoice VLAN
Show answerCorrect answer: A

On an 802.1Q trunk, the native VLAN is the VLAN whose frames are typically sent untagged. The other terms describe different VLAN roles or are not the trunk's untagged-VLAN setting.

Question 4

A data center link is experiencing congestion, and an operator wants to identify whether packets are being discarded because a configured traffic-class queue is full. Which information is most useful to inspect?

  1. AQueue and interface drop counters
  2. BThe device's DNS cache
  3. CThe switch's system hostname
  4. DThe endpoint's ARP age timer
Show answerCorrect answer: A

Interface and queue counters can show congestion-related drops and help identify which traffic class or egress path is affected. DNS, hostname, and ARP-aging information do not directly reveal queue overflow.

Question 5

In a VXLAN deployment, what is the primary role of a VTEP?

  1. AAssigning IP addresses to hosts
  2. BEncapsulating and decapsulating VXLAN traffic
  3. CElecting the spanning-tree root bridge
  4. DAuthenticating users through 802.1X
Show answerCorrect answer: B

A VXLAN Tunnel Endpoint performs VXLAN encapsulation for traffic entering the overlay and decapsulation for traffic leaving it. VTEPs may be implemented on switches or hosts.

Question 6

An administrator wants to reduce the chance that a rogue device can become the spanning-tree root by sending superior bridge information. Which control is intended to protect a designated access port against this event?

  1. ARoot guard
  2. BBPDU filter
  3. CPortFast
  4. DStorm control
Show answerCorrect answer: A

Root guard prevents a port from becoming a root port when it receives superior BPDUs, helping preserve the intended spanning-tree root placement. It is typically applied where a downstream device should not become root.

Question 7

A network team wants to verify that a device's clock remains synchronized with a trusted time source. Which protocol is commonly used?

  1. ANTP
  2. BSNMP
  3. CTFTP
  4. DRADIUS
Show answerCorrect answer: A

Network Time Protocol (NTP) synchronizes clocks on networked devices. Consistent time supports useful event ordering in logs and troubleshooting.

How to use this practice test

The free practice bank contains 50 questions; each session presents up to 20 random questions. Answer a session to see results, then use missed items to identify concepts to revisit, such as VLAN forwarding, VXLAN roles, queue drops, or switch-management practices.

Preparation tips

  • Trace tagged and untagged frames across a trunk, and distinguish VLAN separation from routing between VLANs.
  • Sketch the VXLAN data path and label the VTEP’s encapsulation and decapsulation role.
  • For congestion scenarios, relate traffic-class queue counters and drop information to the affected interface and class.
  • Review spanning-tree protections for access ports, including how they prevent an unauthorized device from becoming root.
  • Practice operational checks for NTP synchronization, SNMP monitoring, management-interface reachability, and configuration backup before upgrades.
