Question 130

A guest SSID is connected to a network that allows lateral traffic into staff database servers. Which immediate engineering change most directly addresses this issue?

  1. Use named administrator identities and centrally audited AAA with appropriate role permissions.
  2. Replace defaults using credential management and restrict administrative access to approved operators.
  3. Apply a narrow guest access policy that blocks internal protected prefixes and permits only approved guest services.
  4. Enforce role-based access specific to user/device class and review least-privilege requirements.

Explanation

Correct Answer

C:

The underlying issue is that the guest role's effective firewall policy permits unintended east-west and internal traffic. This intervention addresses that cause directly. A useful result to confirm is: guests can access permitted internet destinations while protected networks remain unreachable.

Incorrect Answers

A:

This is suited to a different condition, such as when a facilities vendor uses a shared switch administrator account, and investigators cannot attribute a recent unauthorized configuration change. The reported fault instead arises because the guest role's effective firewall policy permits unintended east-west and internal traffic.

B:

This is suited to a different condition, such as when an employee access switch accepts default administrative passwords from a factory deployment image. The reported fault instead arises because the guest role's effective firewall policy permits unintended east-west and internal traffic.

D:

This is suited to a different condition, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. The reported fault instead arises because the guest role's effective firewall policy permits unintended east-west and internal traffic.

Question 131

An employee access switch accepts default administrative passwords from a factory deployment image. Which immediate engineering change most directly addresses this issue?

  1. Place device management in a controlled management VRF or network with source ACLs and operator AAA.
  2. Assign a time-bound minimal troubleshooting role or policy allowing only required destinations.
  3. Replace defaults using credential management and restrict administrative access to approved operators.
  4. Require server identity and certificate-chain validation through managed WLAN profiles.

Explanation

Correct Answer

C:

The underlying issue is that factory-default credentials can grant unauthorized management access. This intervention addresses that cause directly. A useful result to confirm is: only approved identity-controlled administrative sessions succeed and old defaults fail.

Incorrect Answers

A:

This is suited to a different condition, such as when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions. The reported fault instead arises because factory-default credentials can grant unauthorized management access.

B:

This is suited to a different condition, such as when a network engineer opens full access for contractors to troubleshoot one campus printer. The reported fault instead arises because factory-default credentials can grant unauthorized management access.

D:

This is suited to a different condition, such as when a wireless team enables WPA3-Enterprise on a protected SSID, but users are allowed to ignore certificate-validation failures in their supplicant profiles. The reported fault instead arises because factory-default credentials can grant unauthorized management access.

Question 132

A facilities vendor uses a shared switch administrator account, and investigators cannot attribute a recent unauthorized configuration change. Which immediate engineering change most directly addresses this issue?

  1. Use a supported protected AAA transport or secure network path with credential confidentiality controls.
  2. Replace defaults using credential management and restrict administrative access to approved operators.
  3. Revoke and rotate the token, grant a minimum required API scope and move secrets to secure storage.
  4. Use named administrator identities and centrally audited AAA with appropriate role permissions.

Explanation

Correct Answer

D:

The underlying issue is that a shared account hides which individual initiated a high-risk management operation. This intervention addresses that cause directly. A useful result to confirm is: each configuration change is linked to an authorized named operator.

Incorrect Answers

A:

This is suited to a different condition, such as when a campus uses an unencrypted RADIUS configuration across a transport network where message content protection is mandated. The reported fault instead arises because a shared account hides which individual initiated a high-risk management operation.

B:

This is suited to a different condition, such as when an employee access switch accepts default administrative passwords from a factory deployment image. The reported fault instead arises because a shared account hides which individual initiated a high-risk management operation.

C:

This is suited to a different condition, such as when a campus audit finds an old read-write API token embedded in a network monitoring script shared with vendors. The reported fault instead arises because a shared account hides which individual initiated a high-risk management operation.

Question 133

A campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring. Which immediate engineering change most directly addresses this issue?

  1. Apply a narrow guest access policy that blocks internal protected prefixes and permits only approved guest services.
  2. Validate trusted issuer chain, certificate purpose, revocation and required identity properties.
  3. Migrate supported monitoring to SNMPv3 authentication and privacy with least-privilege access.
  4. Disable Telnet and use encrypted SSH management restricted by ACL or management VRF.

Explanation

Correct Answer

C:

The underlying issue is that community-string-based access lacks the per-user authenticated privacy required by the policy. This intervention addresses that cause directly. A useful result to confirm is: monitoring works with approved SNMPv3 security settings and old insecure access is disabled.

Incorrect Answers

A:

This is suited to a different condition, such as when a guest SSID is connected to a network that allows lateral traffic into staff database servers. The reported fault instead arises because community-string-based access lacks the per-user authenticated privacy required by the policy.

B:

This is suited to a different condition, such as when an onboarding policy accepts any device certificate even when its issuing authority is not the organization's trusted CA. The reported fault instead arises because community-string-based access lacks the per-user authenticated privacy required by the policy.

D:

This is suited to a different condition, such as when a switch permits plaintext Telnet administrative sessions across an untrusted guest management segment. The reported fault instead arises because community-string-based access lacks the per-user authenticated privacy required by the policy.

Question 134

A switch permits plaintext Telnet administrative sessions across an untrusted guest management segment. Which immediate engineering change most directly addresses this issue?

  1. Use 802.1X enterprise authentication with a supported central AAA policy and individual or device credentials.
  2. Migrate supported monitoring to SNMPv3 authentication and privacy with least-privilege access.
  3. Remove the legacy broad permit and authorize only required application flows to the NAC service.
  4. Disable Telnet and use encrypted SSH management restricted by ACL or management VRF.

Explanation

Correct Answer

D:

The underlying issue is that plaintext remote administration exposes credentials and configuration traffic. This intervention addresses that cause directly. A useful result to confirm is: only encrypted authorized management sessions reach the device.

Incorrect Answers

A:

This is suited to a different condition, such as when a company wants enterprise WLAN admission but plans to deploy a shared WPA2 personal passphrase to every employee. The reported fault instead arises because plaintext remote administration exposes credentials and configuration traffic.

B:

This is suited to a different condition, such as when a campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring. The reported fault instead arises because plaintext remote administration exposes credentials and configuration traffic.

C:

This is suited to a different condition, 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 reported fault instead arises because plaintext remote administration exposes credentials and configuration traffic.

Question 135

A network engineer opens full access for contractors to troubleshoot one campus printer. Which immediate engineering change most directly addresses this issue?

  1. Place device management in a controlled management VRF or network with source ACLs and operator AAA.
  2. Disable Telnet and use encrypted SSH management restricted by ACL or management VRF.
  3. Migrate supported monitoring to SNMPv3 authentication and privacy with least-privilege access.
  4. Assign a time-bound minimal troubleshooting role or policy allowing only required destinations.

Explanation

Correct Answer

D:

The underlying issue is that overbroad access for a narrow support task violates least-privilege controls. This intervention addresses that cause directly. A useful result to confirm is: the contractor reaches the specified printer service but unrelated subnets remain blocked.

Incorrect Answers

A:

This is suited to a different condition, such as when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions. The reported fault instead arises because overbroad access for a narrow support task violates least-privilege controls.

B:

This is suited to a different condition, such as when a switch permits plaintext Telnet administrative sessions across an untrusted guest management segment. The reported fault instead arises because overbroad access for a narrow support task violates least-privilege controls.

C:

This is suited to a different condition, such as when a campus exposes SNMPv2 community strings over a shared operations network despite a requirement for authenticated encrypted monitoring. The reported fault instead arises because overbroad access for a narrow support task violates least-privilege controls.

Question 136

An onboarding policy accepts any device certificate even when its issuing authority is not the organization's trusted CA. Which immediate engineering change most directly addresses this issue?

  1. Validate trusted issuer chain, certificate purpose, revocation and required identity properties.
  2. Revoke and rotate the token, grant a minimum required API scope and move secrets to secure storage.
  3. Place device management in a controlled management VRF or network with source ACLs and operator AAA.
  4. Disable Telnet and use encrypted SSH management restricted by ACL or management VRF.

Explanation

Correct Answer

A:

The underlying issue is that without certificate trust checks, an arbitrary certificate does not prove approved device identity. This intervention addresses that cause directly. A useful result to confirm is: trusted managed certificates authenticate and untrusted or revoked certificates fail.

Incorrect Answers

B:

This is suited to a different condition, such as when a campus audit finds an old read-write API token embedded in a network monitoring script shared with vendors. The reported fault instead arises because without certificate trust checks, an arbitrary certificate does not prove approved device identity.

C:

This is suited to a different condition, such as when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions. The reported fault instead arises because without certificate trust checks, an arbitrary certificate does not prove approved device identity.

D:

This is suited to a different condition, such as when a switch permits plaintext Telnet administrative sessions across an untrusted guest management segment. The reported fault instead arises because without certificate trust checks, an arbitrary certificate does not prove approved device identity.

Question 137

An IoT camera VLAN receives full access to network management interfaces because the firewall default rule is permissive. Which immediate engineering change most directly addresses this issue?

  1. Create explicit least-privilege allow rules for required camera services and deny management access.
  2. Require server identity and certificate-chain validation through managed WLAN profiles.
  3. Enforce role-based access specific to user/device class and review least-privilege requirements.
  4. Place device management in a controlled management VRF or network with source ACLs and operator AAA.

Explanation

Correct Answer

A:

The underlying issue is that a default permit grants camera devices unnecessary access to privileged management networks. This intervention addresses that cause directly. A useful result to confirm is: camera streaming works while management-plane requests from the IoT role are denied.

Incorrect Answers

B:

This is suited to a different condition, such as when a wireless team enables WPA3-Enterprise on a protected SSID, but users are allowed to ignore certificate-validation failures in their supplicant profiles. The reported fault instead arises because a default permit grants camera devices unnecessary access to privileged management networks.

C:

This is suited to a different condition, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. The reported fault instead arises because a default permit grants camera devices unnecessary access to privileged management networks.

D:

This is suited to a different condition, such as when a campus switch uses a production network as its management source without restricting who can initiate SSH sessions. The reported fault instead arises because a default permit grants camera devices unnecessary access to privileged management networks.

Question 138

An access switch detects unauthorized MAC addresses but the operator plans to disable all port controls to restore a single legitimate printer. Which immediate engineering change most directly addresses this issue?

  1. Enforce role-based access specific to user/device class and review least-privilege requirements.
  2. Correct the printer's authorized identity or endpoint profile while preserving edge security.
  3. Use 802.1X enterprise authentication with a supported central AAA policy and individual or device credentials.
  4. Revoke and rotate the token, grant a minimum required API scope and move secrets to secure storage.

Explanation

Correct Answer

B:

The underlying issue is that the endpoint identity inventory is wrong; removing every control would also admit unauthorized devices. This intervention addresses that cause directly. A useful result to confirm is: the documented printer connects while unknown identities remain restricted.

Incorrect Answers

A:

This is suited to a different condition, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. The reported fault instead arises because the endpoint identity inventory is wrong; removing every control would also admit unauthorized devices.

C:

This is suited to a different condition, such as when a company wants enterprise WLAN admission but plans to deploy a shared WPA2 personal passphrase to every employee. The reported fault instead arises because the endpoint identity inventory is wrong; removing every control would also admit unauthorized devices.

D:

This is suited to a different condition, such as when a campus audit finds an old read-write API token embedded in a network monitoring script shared with vendors. The reported fault instead arises because the endpoint identity inventory is wrong; removing every control would also admit unauthorized devices.

Question 139

A campus audit finds an old read-write API token embedded in a network monitoring script shared with vendors. Which immediate engineering change most directly addresses this issue?

  1. Enforce role-based access specific to user/device class and review least-privilege requirements.
  2. Use named administrator identities and centrally audited AAA with appropriate role permissions.
  3. Require server identity and certificate-chain validation through managed WLAN profiles.
  4. Revoke and rotate the token, grant a minimum required API scope and move secrets to secure storage.

Explanation

Correct Answer

D:

The underlying issue is that an exposed high-privilege token permits unintended configuration operations from script access. This intervention addresses that cause directly. A useful result to confirm is: the old token is rejected and the monitoring workflow uses a narrowly scoped replacement.

Incorrect Answers

A:

This is suited to a different condition, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. The reported fault instead arises because an exposed high-privilege token permits unintended configuration operations from script access.

B:

This is suited to a different condition, such as when a facilities vendor uses a shared switch administrator account, and investigators cannot attribute a recent unauthorized configuration change. The reported fault instead arises because an exposed high-privilege token permits unintended configuration operations from script access.

C:

The reported fault instead arises because an exposed high-privilege token permits unintended configuration operations from script access.

Question 140

A guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. Which immediate engineering change most directly addresses this issue?

  1. Install a valid certificate whose subject alternative names and trust chain match the captive portal endpoint.
  2. Enforce role-based access specific to user/device class and review least-privilege requirements.
  3. Use stronger device identity, network-access authentication or validated profiling evidence rather than hostname alone.
  4. Replace defaults using credential management and restrict administrative access to approved operators.

Explanation

Correct Answer

A:

The underlying issue is that the certificate identity check fails before users can safely trust the HTTPS portal. This intervention addresses that cause directly. A useful result to confirm is: browsers establish authenticated HTTPS sessions to the expected portal hostname.

Incorrect Answers

B:

This is suited to a different condition, such as when a switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. The reported fault instead arises because the certificate identity check fails before users can safely trust the HTTPS portal.

C:

This is suited to a different condition, such as when a printer is allowed into a protected VLAN solely because its hostname matches an approved naming prefix. The reported fault instead arises because the certificate identity check fails before users can safely trust the HTTPS portal.

D:

This is suited to a different condition, such as when an employee access switch accepts default administrative passwords from a factory deployment image. The reported fault instead arises because the certificate identity check fails before users can safely trust the HTTPS portal.
