質問 # 17
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?
- A. WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.
- B. WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.
- C. WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses
802.1X authentication. - D. WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.
正解：B
解説：
WPA3-Enterprise enhances network security over WPA2-Enterprise through several improvements, one of which is the ability to operate in CNSA (Commercial National Security Algorithm) mode. This mode mandates the use of secure cryptographic algorithms during the 802.11 association process, ensuring that all communications are highly secure. The CNSA suite provides stronger encryption standards designed to protect sensitive government, military, and industrial communications. Unlike WPA2, WPA3's CNSA mode uses stronger cryptographic primitives, such as AES-256 in Galois/Counter Mode (GCM) for encryption and SHA-384 for hashing, which are not standard in WPA2-Enterprise.
質問 # 18
You are setting up an Aruba mobility solution which includes a Mobility Master (MM), Mobility Controllers (MCs), and campus APs (CAPs) for a university. The university plans to enforce WPA2-Enterprise for all users' connections. The university wants to apply one set of access control rules to faculty users' traffic and a different set of rules to students' traffic.
What is the best approach for applying the correct rules to each group?
- A. Create two roles, a "faculty" role and a "student" role. Apply firewall policies with the correct rules for each group to each role.
- B. Create two WLANs, one for faculty and one for students. Apply firewall policies with the correct rules for each group to each WLAN.
- C. Create two VLANs, one for faculty and one for students. Apply firewall policies with the correct rules for each group to each VLAN.
- D. Create two VLANs, one for faculty and one for students. Create one set of firewall access control rules that specify faculty IP addresses for the source and a second set of rules that specify the student IP addresses for the source. Apply the rules to the WLAN.
正解：A
解説：
To differentiate access control for faculty and students, the best approach is to use roles. By creating two roles - "faculty" and "student" - and applying the appropriate firewall policies to each, the university can enforce different access rules for each group. This is more efficient than managing multiple VLANs or WLANs because it allows for role-based access control, which is directly tied to user identity rather than just IP addresses or the network they are connected to.

- B. There is no need to locate the AP If the Aruba solution is properly configured to automatically contain it.
- C. There is no need to locale the AP If you manually contain It.
- D. For forensic purposes, you should copy out logs with relevant information, such as the time mat the AP was detected and the AP's MAC address.
- E. You should receive permission before containing an AP. as this action could have legal Implications.
正解：D、E
解説：
When responding to the detection of a Rogue AP, it's important to consider legal implications and to gather forensic evidence:
You should receive permission before containing an AP (Option C), as containing it could disrupt service and may have legal implications, especially if the AP is on a network that the organization does not own.
For forensic purposes, it is essential to document the event by copying out logs with relevant information, such as the time the AP was detected and the AP's MAC address (Option D). This information could be crucial if legal action is taken or if a detailed analysis of the security breach is required.
Automatically containing an AP without consideration for the context (Options A and E) can be problematic, as it might inadvertently interfere with neighboring networks and cause legal issues. Immediate containment without consideration of company policy (Option B) could also violate established incident response procedures.

質問 # 34
What is a use case for Transport Layer Security (TLS)?
- A. to establish a framework for devices to determine when to trust other devices' certificates
- B. to enable a client and a server to establish secure communications for another protocol
- C. to enable two parties to asymmetrically encrypt and authenticate all data that passes be-tween them
- D. to provide a secure alternative to certificate authentication that is easier to implement
正解：B
解説：
The use case for Transport Layer Security (TLS) is to enable a client and a server to establish secure communications for another protocol. TLS is a cryptographic protocol designed to provide secure communication over a computer network. It is widely used for web browsers and other applications that require data to be securely exchanged over a network, such as file transfers, VPN connections, and voice-over-IP (VoIP). TLS operates between the transport layer and the application layer of the Internet Protocol Suite and is used to secure various other protocols like HTTP (resulting in HTTPS), SMTP, IMAP, and more. This protocol ensures privacy and data integrity between two communicating applications.
Detailed information about TLS and its use cases can be found in IETF RFC 5246, which outlines the specifications for TLS 1.2, and in subsequent RFCs that define TLS 1.3.
質問 # 35 
A company has an Aruba Instant AP cluster. A Windows 10 client is attempting to connect a WLAN that enforces WPA3-Enterprise with authentication to 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 EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster
- B. whether the client has a valid certificate installed on it to let it support EAP-TLS
- C. whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster
- D. whether the client has a third-party 802.1 X supplicant, as Windows 10 does not support EAP-TLS
正解：B
解説：
In the context of WPA3-Enterprise with EAP-TLS authentication, the error message "Client doesn't support configured EAP methods" suggests that the client is not able to complete the EAP-TLS authentication process. EAP-TLS requires that both the server (in this case, CPPM) and the client have a valid certificate for mutual authentication. Windows 10 does support EAP-TLS natively, so options A, C, and D can be ruled out.
The most likely reason for the authentication failure is that the client device does not have the correct client certificate installed, which is required to establish a TLS session with the server. Therefore, ensuring that the client has a valid certificate installed that matches the server's requirements is the correct step to resolve this issue.
質問 # 36

- C. In WPA3-Personal, the PMK is the same for each session and is communicated to clients that authenticate
- D. In WPA3-Personal, the PMK is derived directly from the passphrase and is the same tor every session.
正解：A
質問 # 37
What is a guideline for creating certificate signing requests (CSRs) and deploying server Certificates on ArubaOS Mobility Controllers (MCs)?
- A. Create the CSR online using the MC Web Ul if your company requires you to archive the private key.
- B. Create the CSR and public/private keypair offline If you want to install the same certificate on multiple MCs.
- C. Generate the private key online, but the public key and CSR offline, to install the same certificate on multiple MCs.
- D. if you create the CSR and public/private Keypair offline, create a matching private key online on the MC.
正解：B
解説：
Creating the Certificate Signing Request (CSR) and the public/private keypair offline is recommended when deploying server certificates on multiple ArubaOS Mobility Controllers (MCs). This method enhances security by minimizing the exposure of private keys. By creating and handling these components offline, administrators can maintain better control over the keys and ensure their security before deploying them across multiple devices. This approach also simplifies the management of certificates on multiple controllers, as the same certificate can be installed more securely and efficiently.References:
