HPE Network Security Expert Written Exam 認定 HPE7-A10 試験問題 (Q23-Q28):

質問 # 23
A company wants its AOS-CX switches to obtain certificates from ClearPass Onboard and use those certificates to implement RadSec with ClearPass Policy Manager (CPPM).
ClearPass Onboard has a CA with EST enabled and this EST URL: `[https://cp1.acnsxtest.com/.well-known
/est/ca:2](https://cp1.acnsxtest.com/.well-known/est/ca:2)`
ClearPass Guest has an account whose username is `switchcorp123`. (Assume CPPM also has a valid service to authenticate users who access the EST application.) CPPM has a network-device account for the switches with RadSec enabled. The RadSec settings validate by CN or SAN using this regex: `switchcorp123` ClearPass has these certificates:
* HTTPS certificate signed by DigiCert
* RadSec certificate signed by DigiCert
* RADIUS/EAP certificate signed by MyDomainCA
This configuration is on the AOS-CX switches:
```text
crypto pki est-profile est1
url https://clearpass1.acnsxtest.com/.well-known/est/ca:2
username switchcorp123
password plaintext %FY212h & zaTk
vrf default
exit
crypto pki certificate cert1
subject switchcorp123
enroll est-profile onboard
crypto pki application radsec-client certificate cert1
```
The switches' TA-profile list includes DigiCert.
Assume you have obtained the correct password associated with the indicated username. What error or errors are present?

A. The URL in the EST profile is incorrect, and the common name in the EST profile is incorrect.
B. Only the URL in the EST profile is incorrect.
C. Only the username in the EST profile is incorrect.
D. The URL in the EST profile is incorrect, and the switch does not trust a necessary CA.

正解：B

解説：
In AOS-CX Public Key Infrastructure (PKI), Enrollment over Secure Transport (EST, RFC 7030) automates certificate provisioning and renewal. To establish the initial TLS handshake to enroll for a certificate, the switch validates the server certificate presented by the EST server against its configured Trust Anchor (TA) profiles.
In this scenario, ClearPass presents an HTTPS certificate signed by DigiCert. Because the switch's TA-profile list includes DigiCert, cryptographic trust for the EST connection is established. Furthermore, the Subject specified in the certificate profile (`switchcorp123`) matches the validation regular expression configured in the CPPM RadSec device profile.
The defect lies in the EST profile configuration:
The active Onboard EST endpoint is `[https://cp1.acnsxtest.com/.well-known/est/ca:2](https://cp1.acnsxtest.
com/.well-known/est/ca:2)`. However, the switch profile is configured with `[https://clearpass1.acnsxtest.
com/.well-known/est/ca:2] (https://clearpass1.acnsxtest.com/.well-known/est/ca:2)`. Because `clearpass1.
acnsxtest.com` does not match the published FQDN of the server, the switch will experience DNS resolution errors or TLS hostname validation mismatches during enrollment. No other parameters are misconfigured, making "Only the URL in the EST profile is incorrect" the accurate diagnosis.

質問 # 24
Introduction to the customer
You are assisting a company with adding HPE Aruba Networking ClearPass to its network, which uses HPE Aruba Networking network-infrastructure devices.
The company already has a Windows domain and Windows CA. The Windows CA issues certificates to domain computers, domain users, and servers such as domain controllers.

ClearPass cluster IP addressing and hostnames
Publisher = 10.47.47.5
Subscriber 1 = 10.47.47.6
Subscriber 2 = 10.47.47.7
Virtual IP with Subscriber 1 and Subscriber 2 = 10.47.47.8
Refer to the scenario.
You imported the root certificate for the Windows CA into the ClearPass CA Trust list. Based on the scenario requirements, which usages should be added to it?

A. EAP and AD/LDAP Server
B. Radsec and HPE Aruba Networking infrastructure
C. LDAP and HPE Aruba Networking infrastructure
D. EAP and Radsec

正解：A

解説：
In ClearPass Policy Manager, the Certificate Authority (CA) Trust List enforces strict trust domain separation using granular usage flags. When an enterprise root or intermediate CA certificate is imported, administrators must assign specific trust usages depending on which subsystems will validate certificates signed by that authority.
1. **EAP Usage**: The Windows CA issues user and computer authentication certificates used for 802.1X
/EAP-TLS (or TEAP) client authentication. ClearPass must validate the cryptographic trust chain of these incoming client certificates during RADIUS authentication; therefore, the `EAP` usage is required.
2. **AD/LDAP Server Usage**: ClearPass queries Active Directory Domain Controllers for authentication and authorization over secure transport (LDAPS over port 636 or StartTLS). The Domain Controllers present directory server certificates issued by the internal Windows Enterprise CA. To validate the TLS identity of the domain controllers during LDAPS handshakes, ClearPass requires the `AD/LDAP Server` usage flag on the root CA.
Usages such as RadSec or HPE Aruba Networking Infrastructure apply strictly to RADIUS-over-TLS communication with network access devices and device management tunnels, which are unrelated to Windows CA client and directory certificates.

質問 # 25
Refer to the scenario.
A customer uses an AOS-10 architecture managed by HPE Aruba Networking Central. HPE Aruba Networking infrastructure devices authenticate clients to an HPE Aruba Networking ClearPass cluster.
In HPE Aruba Networking Central, you are reviewing network traffic flows for a wireless IoT device categorized as a "Raspberry Pi" client. You observe SSH traffic. You then examine several additional wireless IoT clients and find that they are also sending SSH.
You want a relatively easy way to communicate to HPE Aruba Networking CPPM that an IoT client has used SSH.
What is one prerequisite?

A. Obtain a data collector token from HPE Aruba Networking Central's platform integration settings.
B. In CPPM's CA trust list, add the HPE Aruba Networking Infrastructure usage to the DigiCert certificate.
C. Create an API application and token within the REST API settings.
D. Enable event processing on subscribers in the ClearPass cluster.

正解：A

解説：
Integrating HPE Aruba Networking ClearPass Policy Manager with Central's Client Insights / Device Insight telemetry framework requires establishing an authenticated, secure registration conduit between the on- premises ClearPass cluster and the customer's Central cloud tenant.
To establish this link, the administrator must navigate within HPE Aruba Networking Central to **Platform Integration > Data Collectors** and generate a unique Data Collector Registration Token. In ClearPass Policy Manager, under **Administration > Server Manager > Server Configuration > Device Insight Integration**, this registration token is entered into the setup dialog. ClearPass uses this cryptographic token to authenticate to the Central microservices bus, bind the CPPM cluster to the tenant, and authorize the bi-directional streaming of client telemetry, behavioral tags, and endpoint context data.
