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.

Question 141

A wireless team enables WPA3-Enterprise on a protected SSID, but users are allowed to ignore certificate-validation failures in their supplicant profiles. Which immediate engineering change most directly addresses this issue?

  1. Revoke and rotate the token, grant a minimum required API scope and move secrets to secure storage.
  2. Require server identity and certificate-chain validation through managed WLAN profiles.
  3. Install a valid certificate whose subject alternative names and trust chain match the captive portal endpoint.
  4. Correct the printer's authorized identity or endpoint profile while preserving edge security.

Explanation

Correct Answer

B:

The underlying issue is that strong WLAN encryption does not prevent credential leakage to a rogue RADIUS server when clients ignore server certificates. This intervention addresses that cause directly. A useful result to confirm is: managed clients reject untrusted authentication servers and join legitimate enterprise WLANs.

Incorrect Answers

A:

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 strong WLAN encryption does not prevent credential leakage to a rogue RADIUS server when clients ignore server certificates.

C:

This is suited to a different condition, such as when a guest web portal redirects successfully but browsers report that its TLS certificate does not match the portal hostname. The reported fault instead arises because strong WLAN encryption does not prevent credential leakage to a rogue RADIUS server when clients ignore server certificates.

D:

This is suited to a different condition, such as when an access switch detects unauthorized MAC addresses but the operator plans to disable all port controls to restore a single legitimate printer. The reported fault instead arises because strong WLAN encryption does not prevent credential leakage to a rogue RADIUS server when clients ignore server certificates.

Question 142

A campus switch uses a production network as its management source without restricting who can initiate SSH sessions. 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. Validate trusted issuer chain, certificate purpose, revocation and required identity properties.
  3. Use stronger device identity, network-access authentication or validated profiling evidence rather than hostname alone.
  4. Use a supported protected AAA transport or secure network path with credential confidentiality controls.

Explanation

Correct Answer

A:

The underlying issue is that management exposure to ordinary client segments increases the risk of unauthorized administrative access. This intervention addresses that cause directly. A useful result to confirm is: authorized operators connect while normal user clients cannot reach management services.

Incorrect Answers

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 management exposure to ordinary client segments increases the risk of unauthorized administrative access.

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 management exposure to ordinary client segments increases the risk of unauthorized administrative access.

D:

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 management exposure to ordinary client segments increases the risk of unauthorized administrative access.

Question 143

A printer is allowed into a protected VLAN solely because its hostname matches an approved naming prefix. 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. Replace defaults using credential management and restrict administrative access to approved operators.
  3. Use stronger device identity, network-access authentication or validated profiling evidence rather than hostname alone.
  4. Disable Telnet and use encrypted SSH management restricted by ACL or management VRF.

Explanation

Correct Answer

C:

The underlying issue is that hostnames are user-changeable labels and do not establish trustworthy device ownership. This intervention addresses that cause directly. A useful result to confirm is: approved printers obtain the intended policy, while an attacker spoofing a printer name does not.

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 hostnames are user-changeable labels and do not establish trustworthy device ownership.

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 hostnames are user-changeable labels and do not establish trustworthy device ownership.

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 hostnames are user-changeable labels and do not establish trustworthy device ownership.

Question 144

A switch administrator attempts to apply a full-access policy to every authenticated wired client to simplify ticket handling. 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. Enforce role-based access specific to user/device class and review least-privilege requirements.
  3. Validate trusted issuer chain, certificate purpose, revocation and required identity properties.
  4. Correct the printer's authorized identity or endpoint profile while preserving edge security.

Explanation

Correct Answer

B:

The underlying issue is that authentication confirms identity but does not justify universal authorization to all services. This intervention addresses that cause directly. A useful result to confirm is: each class can reach its approved resources while restricted destinations remain blocked.

Incorrect Answers

A:

This is suited to a different condition, such as when an IoT camera VLAN receives full access to network management interfaces because the firewall default rule is permissive. The reported fault instead arises because authentication confirms identity but does not justify universal authorization to all services.

C:

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 authentication confirms identity but does not justify universal authorization to all services.

D:

This is suited to a different condition, such as when an access switch detects unauthorized MAC addresses but the operator plans to disable all port controls to restore a single legitimate printer. The reported fault instead arises because authentication confirms identity but does not justify universal authorization to all services.

Question 145

A branch firewall permits internal IoT devices to initiate sessions to the NAC administration console by a legacy broad access rule. Which immediate engineering change most directly addresses this issue?

  1. Remove the legacy broad permit and authorize only required application flows to the NAC service.
  2. Use a supported protected AAA transport or secure network path with credential confidentiality controls.
  3. Migrate supported monitoring to SNMPv3 authentication and privacy with least-privilege access.
  4. Create explicit least-privilege allow rules for required camera services and deny management access.

Explanation

Correct Answer

A:

The underlying issue is that historic wide access rules create a direct path from low-trust endpoints to sensitive control planes. This intervention addresses that cause directly. A useful result to confirm is: ioT clients retain needed services but NAC administration connections are denied.

Incorrect Answers

B:

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 historic wide access rules create a direct path from low-trust endpoints to sensitive control planes.

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 historic wide access rules create a direct path from low-trust endpoints to sensitive control planes.

D:

This is suited to a different condition, such as when an IoT camera VLAN receives full access to network management interfaces because the firewall default rule is permissive. The reported fault instead arises because historic wide access rules create a direct path from low-trust endpoints to sensitive control planes.

Question 146

A campus uses an unencrypted RADIUS configuration across a transport network where message content protection is mandated. 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. Use stronger device identity, network-access authentication or validated profiling evidence rather than hostname alone.
  3. Replace defaults using credential management and restrict administrative access to approved operators.
  4. Apply a narrow guest access policy that blocks internal protected prefixes and permits only approved guest services.

Explanation

Correct Answer

A:

The underlying issue is that traditional RADIUS transport may not satisfy requirements for encrypted management traffic across untrusted links. This intervention addresses that cause directly. A useful result to confirm is: approved AAA flows remain protected in transit and authentication results remain correct.

Incorrect Answers

B:

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 traditional RADIUS transport may not satisfy requirements for encrypted management traffic across untrusted links.

C:

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 traditional RADIUS transport may not satisfy requirements for encrypted management traffic across untrusted links.

D:

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 traditional RADIUS transport may not satisfy requirements for encrypted management traffic across untrusted links.

Question 147

Staff Wi-Fi clients have correct certificates but the RADIUS server cannot see authentication requests after a network ACL update. Which immediate engineering change most directly addresses this issue?

  1. Update and test the guest authorization state and its valid time window in the policy workflow.
  2. Define a documented outage role with the minimum necessary service and use trusted AAA redundancy.
  3. Allow the configured RADIUS transport between WLAN infrastructure and approved AAA servers.
  4. Use a supported device-profiled MAC authentication fallback with restricted IoT authorization.

Explanation

Correct Answer

C:

The underlying issue is that a network access rule blocks the AAA request or response path before credential validation occurs. This intervention addresses that cause directly. A useful result to confirm is: RADIUS requests and responses arrive and authorized clients complete EAP-TLS.

Incorrect Answers

A:

This is suited to a different condition, such as when a guest sponsor approves a visitor account, but the NAC policy still maps the visitor to the expired guest role. The reported fault instead arises because a network access rule blocks the AAA request or response path before credential validation occurs.

B:

This is suited to a different condition, such as when a remote warehouse has intermittent RADIUS reachability, and the team plans to fail open every corporate user port to restore continuity. The reported fault instead arises because a network access rule blocks the AAA request or response path before credential validation occurs.

D:

This is suited to a different condition, such as when a lab's headless sensors cannot run an 802.1X supplicant, and technicians propose allowing every unknown MAC to bypass access control. The reported fault instead arises because a network access rule blocks the AAA request or response path before credential validation occurs.

Question 148

An access switch performs 802.1X on user ports, but unauthenticated clients are placed into production VLAN by an incorrect fallback policy. Which immediate engineering change most directly addresses this issue?

  1. Restrict the unauthenticated or failure role and map authorized clients through the approved AAA result.
  2. Correct the AAA enforcement profile to return the appropriate role assignment after verifying identity.
  3. Reorder or refine the service matching rules so the proper EAP-TLS service handles the request.
  4. Correct AAA server resolution or target definitions to use genuinely independent reachable endpoints.

Explanation

Correct Answer

A:

The underlying issue is that the current fallback grants production access even without successful identity validation. This intervention addresses that cause directly. A useful result to confirm is: unauthenticated clients stay isolated and compliant users gain expected network service.

Incorrect Answers

B:

This is suited to a different condition, such as when an access controller accepts a staff user from RADIUS but assigns the guest role because the expected role attribute is absent. The reported fault instead arises because the current fallback grants production access even without successful identity validation.

C:

This is suited to a different condition, such as when a ClearPass service selects the wrong authentication source because a generic catch-all service rule matches before the intended EAP-TLS policy. The reported fault instead arises because the current fallback grants production access even without successful identity validation.

D:

This is suited to a different condition, such as when a campus AAA deployment has two RADIUS servers, but requests continue timing out because both hostnames resolve to the same failed address. The reported fault instead arises because the current fallback grants production access even without successful identity validation.

Question 149

A corporate EAP-TLS enrollment works for most laptops but newly issued devices lack the required client certificate. Which immediate engineering change most directly addresses this issue?

  1. Provision a certificate with approved client-authentication purpose and mapped identity attributes.
  2. Allow the configured RADIUS transport between WLAN infrastructure and approved AAA servers.
  3. Deploy the managed certificate profile before requiring enterprise EAP-TLS admission.
  4. Update and test the guest authorization state and its valid time window in the policy workflow.

Explanation

Correct Answer

C:

The underlying issue is that EAP-TLS needs a valid client credential; an empty certificate store cannot prove endpoint identity. This intervention addresses that cause directly. A useful result to confirm is: newly enrolled devices present approved certificates and join without manual exceptions.

Incorrect Answers

A:

This is suited to a different condition, such as when a client presents a valid EAP-TLS certificate but its EKU or identity mapping does not meet the enterprise admission rule. The reported fault instead arises because EAP-TLS needs a valid client credential; an empty certificate store cannot prove endpoint identity.

B:

This is suited to a different condition, such as when staff Wi-Fi clients have correct certificates but the RADIUS server cannot see authentication requests after a network ACL update. The reported fault instead arises because EAP-TLS needs a valid client credential; an empty certificate store cannot prove endpoint identity.

D:

This is suited to a different condition, such as when a guest sponsor approves a visitor account, but the NAC policy still maps the visitor to the expired guest role. The reported fault instead arises because EAP-TLS needs a valid client credential; an empty certificate store cannot prove endpoint identity.

Question 150

An access controller accepts a staff user from RADIUS but assigns the guest role because the expected role attribute is absent. Which immediate engineering change most directly addresses this issue?

  1. Apply supported multi-domain or per-client authorization separating the voice and data devices.
  2. Correct the AAA enforcement profile to return the appropriate role assignment after verifying identity.
  3. Reorder or refine the service matching rules so the proper EAP-TLS service handles the request.
  4. Use supported reauthentication, session controls and revocation handling to terminate unauthorized access promptly.

Explanation

Correct Answer

B:

The underlying issue is that successful authentication alone does not guarantee the intended network authorization attributes. This intervention addresses that cause directly. A useful result to confirm is: the authenticated staff client receives its authorized role and access policy.

Incorrect Answers

A:

This is suited to a different condition, such as when a wired port with both a phone and workstation grants employee access to the phone's unauthenticated identity. The reported fault instead arises because successful authentication alone does not guarantee the intended network authorization attributes.

C:

This is suited to a different condition, such as when a ClearPass service selects the wrong authentication source because a generic catch-all service rule matches before the intended EAP-TLS policy. The reported fault instead arises because successful authentication alone does not guarantee the intended network authorization attributes.

D:

This is suited to a different condition, such as when a corporate certificate was revoked, yet a connected endpoint retains network access indefinitely because no session reauthentication or revocation response occurs. The reported fault instead arises because successful authentication alone does not guarantee the intended network authorization attributes.
