Question 250

At Pine Valley Telecom, the provider infrastructure team is preparing a regional hub modernization. The operational constraint is planned fault-domain isolation. A production-readiness reviewer asks for proof addressing: Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. Which result BEST demonstrates that this specific issue was resolved?

  1. Approved supplicants receive authorized access and unknown clients remain in the intended restricted state.
  2. Access logs identify individual authorized operators and restricted users cannot change protected settings.
  3. A role-by-role test confirms that guests, employees and IoT devices reach only authorized services.
  4. Rogue DHCP offers from edge ports are rejected and the legitimate server lease exchange succeeds.

Explanation

Correct Answer

C:

A role-by-role test confirms that guests, employees and IoT devices reach only authorized services. This is the relevant acceptance observation for the reported issue: Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. The intended corrective choice is: Integrate ClearPass-derived roles or equivalent supported policy assignment and apply least-privilege segmentation. At Pine Valley Telecom, this outcome verifies actual operation under planned fault-domain isolation, rather than only a ticket marked complete.

Incorrect Answers

A:

Approved supplicants receive authorized access and unknown clients remain in the intended restricted state. Such an observation would verify a separate issue: Managed employee laptops should authenticate to wired access but ports are configured for unrestricted admission. It would follow the distinct action: Configure policy-based 802.1X with a supported RADIUS backend and defined failure behavior. Here the reported failure is Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. The decisive result for Pine Valley Telecom must instead be: A role-by-role test confirms that guests, employees and IoT devices reach only authorized services.

B:

Access logs identify individual authorized operators and restricted users cannot change protected settings. Such an observation would verify a separate issue: A shared administrator account has full rights from every network and no centralized audit trace. It would follow the distinct action: Use authenticated role-based administration with AAA and appropriate management-plane restrictions. Here the reported failure is Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. The decisive result for Pine Valley Telecom must instead be: A role-by-role test confirms that guests, employees and IoT devices reach only authorized services.

D:

Rogue DHCP offers from edge ports are rejected and the legitimate server lease exchange succeeds. Such an observation would verify a separate issue: An attacker on an access port sends forged DHCP replies claiming to be the default gateway server. It would follow the distinct action: Use DHCP snooping with trusted uplinks and untrusted edge ports, validating the trust boundary. Here the reported failure is Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. The decisive result for Pine Valley Telecom must instead be: A role-by-role test confirms that guests, employees and IoT devices reach only authorized services.

Question 251

At Fairmont Logistics, the distribution-center switching team is preparing a warehouse device rollout. The operational constraint is critical handheld scanner uptime. The network investigation identifies this condition: Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. Which action BEST corrects the stated problem?

  1. Use DHCP snooping with trusted uplinks and untrusted edge ports, validating the trust boundary.
  2. Integrate ClearPass-derived roles or equivalent supported policy assignment and apply least-privilege segmentation.
  3. Place ordered ACL entries on the appropriate ingress or egress path with explicit required traffic permits.
  4. Configure policy-based 802.1X with a supported RADIUS backend and defined failure behavior.

Explanation

Correct Answer

B:

Integrate ClearPass-derived roles or equivalent supported policy assignment and apply least-privilege segmentation. This response directly addresses the observed condition: Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. For Fairmont Logistics during a warehouse device rollout, the decisive check is not merely that a configuration was entered: A role-by-role test confirms that guests, employees and IoT devices reach only authorized services. That evidence connects the proposed correction to measurable forwarding or management behavior.

Incorrect Answers

A:

Use DHCP snooping with trusted uplinks and untrusted edge ports, validating the trust boundary. That relates to a different fault: An attacker on an access port sends forged DHCP replies claiming to be the default gateway server. The incident in the scenario is instead: Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. Changing the unrelated setting does not establish the required repair at Fairmont Logistics; the relevant confirmation would be: A role-by-role test confirms that guests, employees and IoT devices reach only authorized services.

C:

Place ordered ACL entries on the appropriate ingress or egress path with explicit required traffic permits. That relates to a different fault: An interface ACL blocks legitimate DNS replies because its direction and permit order were not reviewed. The incident in the scenario is instead: Different device roles require distinct network access policies but the switch uses one broad VLAN for everyone. Changing the unrelated setting does not establish the required repair at Fairmont Logistics; the relevant confirmation would be: A role-by-role test confirms that guests, employees and IoT devices reach only authorized services.

D:

Configure policy-based 802.1X with a supported RADIUS backend and defined failure behavior. That relates to a different fault: Managed employee laptops should authenticate to wired access but ports are configured for unrestricted admission.

  3. Approved supplicants receive authorized access and unknown clients remain in the intended restricted state.
  4. Rogue DHCP offers from edge ports are rejected and the legitimate server lease exchange succeeds.

Explanation

Correct Answer

A:

Incorrect Answers

B:

The printer obtains only permitted access while an unknown MAC cannot inherit its rights. Such an observation would verify a separate issue: A network printer cannot run a supplicant and keeps failing strict 802.1X admission. It would follow the distinct action: Use an approved limited MAC-authentication or exception role rather than disabling authentication for the entire closet. Here the reported failure is An interface ACL blocks legitimate DNS replies because its direction and permit order were not reviewed.
