1. 1According to the campus design guide, what is the maximum number of CX 6200 switches in a VSF stack?

   1. A.Four switches
   2. B.Eight switchesCorrect answer: B
   3. C.Ten switches
   4. D.Twelve switches

   Explanation: The guide states: "VSF supports up to 10 members on a 6300 and up to eight members on a 6200." The 6200 limit is eight; ten is the 6300 limit.

2. 2A factory-default AOS-CX switch has network reachability and must be managed from Classic Central. Which provisioning prerequisite must the administrator complete?

   1. A.Assign a subscription and remove it from device inventory.
   2. B.Create a local user without adding it to device inventory.
   3. C.Add it to device inventory and assign a valid subscription.Correct answer: C
   4. D.Add it to device inventory and disable the Central service.

   Explanation: The Classic Central guide states: "To manage AOS-CX switches from Classic Central, you must onboard the switches to the device inventory and assign a valid subscription." Both inventory onboarding and the subscription are required.

3. 3A CX interface is down even though its admin state is up. Its state information reads `Disabled by port-access`. Which subsystem is reported as disabling the interface?

   1. A.Port accessCorrect answer: A
   2. B.VSX split protection
   3. C.Link aggregation control
   4. D.Spanning tree

   Explanation: The security guide example reports "State information: Disabled by port-access" while the admin state is up. It identifies the disabling subsystem; further investigation is needed to establish the underlying violation.

4. 4An administrator makes a remote switch change using checkpoint auto mode but loses access before confirming it. What happens when the specified interval expires?

   1. A.The temporary checkpoint is deleted and the changes remain.
   2. B.The switch remains indefinitely in auto checkpoint mode.
   3. C.The previous runtime configuration is restored.Correct answer: C
   4. D.The new configuration becomes the startup configuration.

   Explanation: The guide states: "Configuration changes must be saved before the interval expires, otherwise the runtime configuration is restored from the temporary checkpoint." The unconfirmed change is reverted when the timer expires.

5. 5A campus aggregation design considers CX 8320, CX 8325 and CX 8360 switches for a VSX pair. Which pairing meets the campus guide's model requirement?

   1. A.Two CX 8325 switchesCorrect answer: A
   2. B.One CX 8325 and one CX 8360
   3. C.One CX 8320 and one CX 8360
   4. D.One CX 8320 and one CX 8325

   Explanation: The guide states: "A VSX pair cannot be mixed between different models, meaning a CX8320 cannot be mixed with a CX 8325." The two switches therefore must be the same model.

6. 6How does Classic Central apply configuration to an AOS-CX switch in a template group?

   1. A.Through CLI-based configuration templates.Correct answer: A
   2. B.Through UI-based group settings only.
   3. C.Through the switch's locally edited CLI only.
   4. D.Through JSON REST payloads as the group's configuration template.

   Explanation: The Classic Central guide states: "Template groups allow you to configure devices using CLI-based configuration templates. UI groups allow you to configure devices using UI-based configuration options." The template group matches the stated configuration method.

7. 7A CX port supports only 10 Gb/s and 25 Gb/s optics, while the installed transceiver operates only at 50 Gb/s. Central reports a transceiver incompatibility. What does the data identify?

   1. A.The transceiver speed is not supported by the port.Correct answer: A
   2. B.The transceiver has exceeded its temperature limit.
   3. C.The link endpoints are configured for different duplex modes.
   4. D.The port supplies insufficient transceiver power.

   Explanation: The guide states: "the switch port does not support the transceiver's speed." The alert concerns the speed relationship between the port and transceiver.

8. 8A CX 6200 administrator needs to restore a previously saved checkpoint to the running configuration. Which command performs that operation?

   1. A.copy running-config checkpoint new1
   2. B.checkpoint rollback ckpt1Correct answer: B
   3. C.checkpoint diff ckpt1 running-config
   4. D.copy running-config startup-config

   Explanation: The guide states: "Applies the configuration from a pre-existing checkpoint or the startup configuration to the running configuration." Rollback applies the selected checkpoint to the running configuration.

9. 9A customer needs a CX 6300 model with hot-swappable power supplies to adjust the PoE power capacity. Which model format meets that requirement?

   1. A.The CX 6300F with rear power supply slots
   2. B.The CX 6300M with built-in power supplies
   3. C.The CX 6300F with its built-in power supplies
   4. D.The CX 6300M with rear power supply slotsCorrect answer: D

   Explanation: The CX 6300 QuickSpecs states: "Fixed format (F) models include built-in power supplies. The modular (M) models have rear slots for hot swappable power supplies that allow you to customize your PoE requirements, and its fans are field replaceable." The M format provides the requested supply slots.

10. 10A switch is moved to a Classic Central UI group with Retain CX-Switch Configuration selected. Its retained device-level RADIUS configuration conflicts with a destination group setting. What happens to the conflicting configuration?

    1. A.The destination group configuration takes precedence.Correct answer: A
    2. B.The retained device configuration always takes precedence.
    3. C.Both conflicting configurations remain active.
    4. D.The switch's conflicting value is reset to its factory default.

    Explanation: The Classic Central guide states: "However, if any retained device configuration conflicts with group-level configuration, then group-level configuration takes precedence, and those conflicting configuration will be replaced." Retaining the device configuration does not override a conflicting group setting.
