Question 330

A guest SSID is connected to a network that allows lateral traffic into staff database servers. Which failure mechanism best explains the observed behavior?

  1. A shared account hides which individual initiated a high-risk management operation.
  2. Community-string-based access lacks the per-user authenticated privacy required by the policy.
  3. The guest role's effective firewall policy permits unintended east-west and internal traffic.
  4. The certificate identity check fails before users can safely trust the HTTPS portal.

Explanation

Correct Answer

C:

The symptoms fit this mechanism. A targeted response is to apply a narrow guest access policy that blocks internal protected prefixes and permits only approved guest services, followed by verification that guests can access permitted internet destinations while protected networks remain unreachable.

Incorrect Answers

A:

That explanation fits a different case, such as when a facilities vendor uses a shared switch administrator account, and investigators cannot attribute a recent unauthorized configuration change. The symptoms here are better explained by the guest role's effective firewall policy permits unintended east-west and internal traffic.

B:

That explanation fits a different case, such as when a campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring. The symptoms here are better explained by the guest role's effective firewall policy permits unintended east-west and internal traffic.

D:

That explanation fits a different case, such as when a guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. The symptoms here are better explained by the guest role's effective firewall policy permits unintended east-west and internal traffic.

Question 331

An employee access switch accepts default administrative passwords from a factory deployment image. Which failure mechanism best explains the observed behavior?

  1. Historic wide access rules create a direct path from low-trust endpoints to sensitive control planes.
  2. The guest role's effective firewall policy permits unintended east-west and internal traffic.
  3. Factory-default credentials can grant unauthorized management access.
  4. Without certificate trust checks, an arbitrary certificate does not prove approved device identity.

Explanation

Correct Answer

C:

The symptoms fit this mechanism. A targeted response is to replace defaults using credential management and restrict administrative access to approved operators, followed by verification that only approved identity-controlled administrative sessions succeed and old defaults fail.

Incorrect Answers

A:

That explanation fits a different case, such as when a branch firewall permits internal IoT devices to initiate sessions to the NAC administration console by a legacy broad access rule. The symptoms here are better explained by factory-default credentials can grant unauthorized management access.

B:

That explanation fits a different case, such as when a guest SSID is connected to a network that allows lateral traffic into staff database servers. The symptoms here are better explained by factory-default credentials can grant unauthorized management access.

D:

That explanation fits a different case, such as when an onboarding policy accepts any device certificate even when its issuing authority is not the organization's trusted CA. The symptoms here are better explained by factory-default credentials can grant unauthorized management access.

Question 332

A facilities vendor uses a shared switch administrator account, and investigators cannot attribute a recent unauthorized configuration change. Which failure mechanism best explains the observed behavior?

  1. The certificate identity check fails before users can safely trust the HTTPS portal.
  2. Traditional RADIUS transport may not satisfy requirements for encrypted management traffic across untrusted links.
  3. Overbroad access for a narrow support task violates least-privilege controls.
  4. A shared account hides which individual initiated a high-risk management operation.

Explanation

Correct Answer

D:

The symptoms fit this mechanism. A targeted response is to use named administrator identities and centrally audited AAA with appropriate role permissions, followed by verification that each configuration change is linked to an authorized named operator.

Incorrect Answers

A:

That explanation fits a different case, such as when a guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. The symptoms here are better explained by a shared account hides which individual initiated a high-risk management operation.

B:

That explanation fits a different case, such as when a campus uses an unencrypted RADIUS configuration across a transport network where message content protection is mandated. The symptoms here are better explained by a shared account hides which individual initiated a high-risk management operation.

C:

That explanation fits a different case, such as when a network engineer opens full access for contractors to troubleshoot one campus printer. The symptoms here are better explained by a shared account hides which individual initiated a high-risk management operation.

Question 333

A campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring. Which failure mechanism best explains the observed behavior?

  1. Overbroad access for a narrow support task violates least-privilege controls.
  2. Without certificate trust checks, an arbitrary certificate does not prove approved device identity.
  3. Factory-default credentials can grant unauthorized management access.
  4. Community-string-based access lacks the per-user authenticated privacy required by the policy.

Explanation

Correct Answer

D:

The symptoms fit this mechanism. A targeted response is to migrate supported monitoring to SNMPv3 authentication and privacy with least-privilege access, followed by verification that monitoring works with approved SNMPv3 security settings and old insecure access is disabled.

Incorrect Answers

A:

That explanation fits a different case, such as when a network engineer opens full access for contractors to troubleshoot one campus printer. The symptoms here are better explained by community-string-based access lacks the per-user authenticated privacy required by the policy.

C:

That explanation fits a different case, such as when an employee access switch accepts default administrative passwords from a factory deployment image. The symptoms here are better explained by community-string-based access lacks the per-user authenticated privacy required by the policy.

Question 334

A switch permits plaintext Telnet administrative sessions across an untrusted guest management segment. Which failure mechanism best explains the observed behavior?

  1. Authentication confirms identity but does not justify universal authorization to all services.
  2. Plaintext remote administration exposes credentials and configuration traffic.
  3. A default permit grants camera devices unnecessary access to privileged management networks.
  4. Overbroad access for a narrow support task violates least-privilege controls.

Explanation

Correct Answer

B:

The symptoms fit this mechanism. A targeted response is to disable Telnet and use encrypted SSH management restricted by ACL or management VRF, followed by verification that only encrypted authorized management sessions reach the device.

Incorrect Answers

A:

That explanation fits a different case, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. The symptoms here are better explained by plaintext remote administration exposes credentials and configuration traffic.

C:

That explanation fits a different case, such as when an IoT camera VLAN receives full access to network management interfaces because the firewall default rule is permissive. The symptoms here are better explained by plaintext remote administration exposes credentials and configuration traffic.

D:

That explanation fits a different case, such as when a network engineer opens full access for contractors to troubleshoot one campus printer. The symptoms here are better explained by plaintext remote administration exposes credentials and configuration traffic.

Question 335

A network engineer opens full access for contractors to troubleshoot one campus printer. Which failure mechanism best explains the observed behavior?

  3. The guest role's effective firewall policy permits unintended east-west and internal traffic.
  4. Management exposure to ordinary client segments increases the risk of unauthorized administrative access.

Explanation

Correct Answer

A:

The symptoms fit this mechanism. A targeted response is to assign a time-bound minimal troubleshooting role or policy allowing only required destinations, followed by verification that the contractor reaches the specified printer service but unrelated subnets remain blocked.

Incorrect Answers

B:

That explanation fits a different case, such as when a facilities vendor uses a shared switch administrator account, and investigators cannot attribute a recent unauthorized configuration change. The symptoms here are better explained by overbroad access for a narrow support task violates least-privilege controls.

C:

That explanation fits a different case, such as when a guest SSID is connected to a network that allows lateral traffic into staff database servers. The symptoms here are better explained by overbroad access for a narrow support task violates least-privilege controls.

D:

That explanation fits a different case, such as when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions. The symptoms here are better explained by overbroad access for a narrow support task violates least-privilege controls.

Question 336

An onboarding policy accepts any device certificate even when its issuing authority is not the organization's trusted CA. Which failure mechanism best explains the observed behavior?

  1. Traditional RADIUS transport may not satisfy requirements for encrypted management traffic across untrusted links.
  2. An exposed high-privilege token permits unintended configuration operations from script access.
  3. Without certificate trust checks, an arbitrary certificate does not prove approved device identity.
  4. Community-string-based access lacks the per-user authenticated privacy required by the policy.

Explanation

Correct Answer

C:

The symptoms fit this mechanism. A targeted response is to validate trusted issuer chain, certificate purpose, revocation and required identity properties, followed by verification that trusted managed certificates authenticate and untrusted or revoked certificates fail.

Incorrect Answers

A:

That explanation fits a different case, such as when a campus uses an unencrypted RADIUS configuration across a transport network where message content protection is mandated. The symptoms here are better explained by without certificate trust checks, an arbitrary certificate does not prove approved device identity.

  2. Management exposure to ordinary client segments increases the risk of unauthorized administrative access.
  3. Overbroad access for a narrow support task violates least-privilege controls.
  4. Historic wide access rules create a direct path from low-trust endpoints to sensitive control planes.

Explanation

Correct Answer

A:

The symptoms fit this mechanism. A targeted response is to create explicit least-privilege allow rules for required camera services and deny management access, followed by verification that camera streaming works while management-plane requests from the IoT role are denied.

Incorrect Answers

B:

That explanation fits a different case, such as when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions. The symptoms here are better explained by a default permit grants camera devices unnecessary access to privileged management networks.

C:

That explanation fits a different case, such as when a network engineer opens full access for contractors to troubleshoot one campus printer. The symptoms here are better explained by a default permit grants camera devices unnecessary access to privileged management networks.

D:

That explanation fits a different case, such as when a branch firewall permits internal IoT devices to initiate sessions to the NAC administration console by a legacy broad access rule. The symptoms here are better explained by a default permit grants camera devices unnecessary access to privileged management networks.

Question 338

An access switch detects unauthorized MAC addresses but the operator plans to disable all port controls to restore a single legitimate printer. Which failure mechanism best explains the observed behavior?

  1. The endpoint identity inventory is wrong; removing every control would also admit unauthorized devices.
  2. The guest role's effective firewall policy permits unintended east-west and internal traffic.
  3. Community-string-based access lacks the per-user authenticated privacy required by the policy.
  4. Historic wide access rules create a direct path from low-trust endpoints to sensitive control planes.

Explanation

Correct Answer

A:

The symptoms fit this mechanism. A targeted response is to correct the printer's authorized identity or endpoint profile while preserving edge security, followed by verification that the documented printer connects while unknown identities remain restricted.

Incorrect Answers

B:

That explanation fits a different case, such as when a guest SSID is connected to a network that allows lateral traffic into staff database servers. The symptoms here are better explained by the endpoint identity inventory is wrong; removing every control would also admit unauthorized devices.

C:

That explanation fits a different case, such as when a campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring. The symptoms here are better explained by the endpoint identity inventory is wrong; removing every control would also admit unauthorized devices.
