질문 # 162
What is one practice that can help you to maintain a digital chain or custody In your network?

A. Ensure that all network Infrastructure devices use RADIUS rather than TACACS+ to authenticate managers
B. Ensure that all network infrastructure devices receive a valid clock using authenticated NTP
C. Enable packet capturing on Instant AP or Mobility Controller (MC) control path on an ongoing basis.
D. Enable packet capturing on Instant AP or Moodily Controller (MC) datepath on an ongoing basis

정답：B

설명：
To maintain a digital chain of custody in a network, a crucial practice is to ensure that all network infrastructure devices receive a valid clock using authenticated Network Time Protocol (NTP). Accurate and synchronized time stamps are essential for creating reliable and legally defensible logs. Authenticated NTP ensures that the time being set on devices is accurate and that the time source is verified, which is necessary for correlating logs from different devices and for forensic analysis.
:
Digital forensics and network security protocols that underscore the importance of accurate timekeeping for maintaining a digital chain of custody.
NTP configuration guidelines for network devices, emphasizing the use of authentication to prevent tampering with clock settings.

질문 # 163
What is social engineering?

A. Hackers use employees to circumvent network security and gather the information they need to launch an attack.
B. Hackers intercept traffic between two users, eavesdrop on their messages, and pretend to be one or both users.
C. Hackers use Artificial Intelligence (Al) to mimic a user's online behavior so they can infiltrate a network and launch an attack.
D. Hackers spoof the source IP address in their communications so they appear to be a legitimate user.

정답：A

설명：
Social engineering in the context of network security refers to the techniques used by hackers to manipulate individuals into breaking normal security procedures and best practices to gain unauthorized access to systems, networks, or physical locations, or for financial gain. Hackers use various forms of deception to trick employees into handing over confidential or personal information that can be used for fraudulent purposes. This definition encompasses phishing attacks, pretexting, baiting, and other manipulative techniques designed to exploit human psychology. Unlike other hacking methods that rely on technical means, social engineering targets the human element of security. to social engineering, its methods, and defense strategies are commonly found in security training manuals, cybersecurity awareness programs, and authoritative resources like those from the SANS Institute or cybersecurity agencies.

질문 # 164
Refer to the exhibit.
A company has an HPE Aruba Networking Instant AP cluster. A Windows 10 client is attempting to connect to a WLAN that enforces WPA3-Enterprise with authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM is configured to require EAP-TLS. The client authentication fails. In the record for this client's authentication attempt on CPPM, you see this alert.
What is one thing that you check to resolve this issue?

A. Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS
B. Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
C. Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster
D. Whether the client has a valid certificate installed on it to let it support EAP-TLS

정답：D

설명：
The scenario involves an HPE Aruba Networking Instant AP (IAP) cluster with a WLAN configured for WPA3-Enterprise security, using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the authentication server. CPPM is set to require EAP-TLS for authentication. A Windows 10 client attempts to connect but fails, and the CPPM Access Tracker shows an error: "Client does not support configured EAP methods," with the error code 9015 under the RADIUS protocol category.
EAP-TLS (Extensible Authentication Protocol - Transport Layer Security) is a certificate-based authentication method that requires both the client (supplicant) and the server (CPPM) to present valid certificates during the authentication process. The error message indicates that the client does not support the EAP method configured on CPPM (EAP-TLS), meaning the client is either not configured to use EAP-TLS or lacks the necessary components to perform EAP-TLS authentication.
Option B, "Whether the client has a valid certificate installed on it to let it support EAP-TLS," is correct. EAP-TLS requires the client to have a valid client certificate issued by a trusted Certificate Authority (CA) that CPPM trusts. If the Windows 10 client does not have a client certificate installed, or if the certificate is invalid (e.g., expired, not trusted by CPPM, or missing), the client cannot negotiate EAP-TLS, resulting in the error seen in CPPM. This is a common issue in EAP-TLS deployments, and checking the client's certificate is a critical troubleshooting step.
Option A, "Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster," is incorrect because the error indicates that CPPM received the authentication request and rejected it due to the client's inability to support EAP-TLS. This suggests that the IAP cluster is correctly configured to use EAP-TLS (as the request reached CPPM with EAP-TLS as the method). The AAA profile on the IAP cluster is likely already set to use EAP-TLS, or the error would be different (e.g., a connectivity or configuration mismatch issue).
Option C, "Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster," is incorrect for a similar reason. The SSID profile on the IAP cluster defines the security settings (e.g., WPA3-Enterprise), and the AAA profile specifies the EAP method. Since the authentication request reached CPPM with EAP-TLS, the IAP cluster is correctly configured to use EAP-TLS.
Option D, "Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS," is incorrect because Windows 10 natively supports EAP-TLS. The built-in Windows 10 802.1X supplicant (Windows WLAN AutoConfig service) supports EAP-TLS, provided a valid client certificate is installed. A third-party supplicant is not required.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
"EAP-TLS requires both the client and the server to present a valid certificate during the authentication process. If the client does not have a valid certificate installed, or if the certificate is not trusted by ClearPass (e.g., the issuing CA is not in the ClearPass trust list), the authentication will fail with an error such as 'Client does not support configured EAP methods' (Error Code 9015). To resolve this, ensure that the client has a valid certificate installed and that the certificate's issuing CA is trusted by ClearPass." (Page 295, EAP-TLS Troubleshooting Section) Additionally, the HPE Aruba Networking Instant 8.11 User Guide notes:
"For WPA3-Enterprise with EAP-TLS, the client must have a valid client certificate installed to authenticate successfully. If the client lacks a certificate or the certificate is invalid, the authentication will fail, and ClearPass will log an error indicating that the client does not support the configured EAP method."

질문 # 165
Which attack is an example or social engineering?

A. An attack exploits an operating system vulnerability and locks out users until they pay the ransom.
B. An email Is used to impersonate a Dank and trick users into entering their bank login information on a fake website page.
C. A hacker eavesdrops on insecure communications, such as Remote Desktop Program (RDP). and discovers login credentials.
D. A user visits a website and downloads a file that contains a worm, which sell-replicates throughout the network.

정답：B

설명：
An example of a social engineering attack is described in option A, where an email is used to impersonate a bank and deceive users into entering their bank login information on a counterfeit website. Social engineering attacks exploit human psychology rather than technical hacking techniques to gain access to systems, data, or personal information. These attacks often involve tricking people into breaking normal security procedures.
The other options describe different types of technical attacks that do not primarily rely on manipulating individuals through deceptive personal interactions.

질문 # 166
What are the roles of 802.1X authenticators and authentication servers?

A. The authenticator stores the user account database, while the server stores access policies.
B. The authenticator supports only EAP, while the authentication server supports only RADIUS.
C. The authenticator is a RADIUS client and the authentication server is a RADIUS server.
D. The authenticator makes access decisions and the server communicates them to the supplicant.

정답：C

설명：
In the 802.1X network access control model, the roles of the authenticator and the authentication server are distinct yet complementary. The authenticator acts as a RADIUS client, which is a network device, like a switch or wireless access point, that directly interfaces with the client machine (supplicant). The authentication server, typically a RADIUS server, is responsible for verifying the credentials provided by the supplicant through the authenticator. This setup helps in separating the duties where the authenticator enforces authentication but does not decide on the validity of the credentials, which is the role of the authentication server.

IEEE 802.1X standard for network access control.
