Verified Exam Questions & Interactive Explanations
Question 1
According to the CCNA 200-301 v1.1 blueprint, how do Cisco Catalyst Center (formerly DNA Center) and modern AIOps platforms utilize Predictive AI versus Generative AI in network management?
✔ Correct Answer: A. Predictive AI forecasts hardware failures and congestion trends using historical telemetry; Generative AI assists engineers via natural-language troubleshooting and config generation.
Technical Explanation: In CCNA 200-301 v1.1 (Domain 6.0 Automation & Programmability), Cisco distinguishes between Predictive AI/ML (analyzing streaming telemetry to predict link saturation, Wi-Fi interference, or transceiver failure before outages occur) and Generative AI (natural language interfaces/copilots that summarize root causes and draft CLI/JSON configurations).
Question 2
Compare Ansible, Puppet, Chef, and Terraform: Which two tools use an Agentless architecture over SSH/NETCONF to automate Cisco IOS-XE network devices? (Choose two.)
✔ Correct Answer: A. Ansible & D. Terraform
Technical Explanation: Ansible (using YAML playbooks over SSH/NETCONF) and Terraform (using declarative HCL and API/SSH providers) are agentless—they do not require installing background software agents on Cisco routers or switches. Puppet and Chef traditionally rely on a Pull model using an installed device agent.
Question 3
An engineer observes increasing CRC and FCS input errors on GigabitEthernet0/1, while 'show interfaces Gi0/1' confirms both ends operate at 1000 Mb/s Full-Duplex with zero collisions. What is the most likely root cause?
✔ Correct Answer: B. A damaged copper cable, faulty SFP transceiver, or electromagnetic interference (EMI) on the physical link.
Technical Explanation: When both ends operate at Full-Duplex and there are no late collisions, rising CRC (Cyclic Redundancy Check) errors point directly to Layer 1 physical signal degradation—such as a bad Patch Cable, dirty fiber optic connector, or EMI.
Question 4
Which Spanning Tree feature prevents an access port or downstream customer switch from becoming the STP Root Bridge by placing the port into 'root-inconsistent' state if superior BPDUs are received?
✔ Correct Answer: B. Root Guard
Technical Explanation: Root Guard (
spanning-tree guard root) is configured on designated ports toward non-core switches. If a superior BPDU (lower Bridge ID) arrives on that port, Root Guard blocks the port in a root-inconsistent state until the superior BPDUs stop, protecting your core Root Bridge election.
Question 5
Examine the REST API HTTP response code '401 Unauthorized' versus '403 Forbidden' when querying Cisco Catalyst Center. What is the difference?
✔ Correct Answer: A. 401 means the API token or credentials are missing/invalid; 403 means authentication succeeded but the user lacks permission for that resource.
Technical Explanation: In RESTful HTTP APIs:
• 200 OK / 201 Created: Success.
• 400 Bad Request: Malformed JSON/URI syntax.
• 401 Unauthorized: Unauthenticated (invalid/expired X-Auth-Token or Basic Auth credentials).
• 403 Forbidden: Authenticated identity does not have RBAC privileges for the endpoint.
• 200 OK / 201 Created: Success.
• 400 Bad Request: Malformed JSON/URI syntax.
• 401 Unauthorized: Unauthenticated (invalid/expired X-Auth-Token or Basic Auth credentials).
• 403 Forbidden: Authenticated identity does not have RBAC privileges for the endpoint.
