HP Aruba Certified Network Security Expert Written Sample Questions:
Refer to the scenario.
A customer has asked you to review their AOS-CX switches for potential vulnerabilities. The configuration for these switches is shown below:
What is one immediate remediation that you should recommend?
- A. Setting the clock manually instead of using NTP
- B. Changing the switch's DNS server to the mgmt VRF
- C. Disabling Telnet
- D. Either disabling DHCPv4-snoopinq or leaving it enabled, but also enabling ARP inspection
Explanation: Only visible for Fast2test members. You can sign-up / login (it's free).
Refer to the scenario.
# Introduction to the customer
You are helping a company add Aruba ClearPass to their network, which uses Aruba network infrastructure devices.
The company currently has a Windows domain and Windows CA. The Window CA issues certificates to domain computers, domain users, and servers such as domain controllers. An example of a certificate issued by the Windows CA is shown here.
The company is in the process of adding Microsoft Endpoint Manager (Intune) to manage its mobile clients.
The customer is maintaining the on-prem AD for now and uses Azure AD Connect to sync with Azure AD.
# Requirements for issuing certificates to mobile clients
The company wants to use ClearPass Onboard to deploy certificates automatically to mobile clients enrolled in Intune. During this process, Onboard should communicate with Azure AD to validate the clients. High availability should also be provided for this scenario; in other words, clients should be able to get certificates from Subscriber 2 if Subscriber 1 is down.
The Intune admins intend to create certificate profiles that include a UPN SAN with the UPN of the user who enrolled the device.
# Requirements for authenticating clients
The customer requires all types of clients to connect and authenticate on the same corporate SSID.
The company wants CPPM to use these authentication methods:
* EAP-TLS to authenticate users on mobile clients registered in Intune
* TEAR, with EAP-TLS as the inner method to authenticate Windows domain computers and the users on them To succeed, EAP-TLS (standalone or as a TEAP method) clients must meet these requirements:
Their certificate is valid and is not revoked, as validated by OCSP
The client's username matches an account in AD
# Requirements for assigning clients to roles
After authentication, the customer wants the CPPM to assign clients to ClearPass roles based on the following rules:
* Clients with certificates issued by Onboard are assigned the "mobile-onboarded" role
* Clients that have passed TEAP Method 1 are assigned the "domain-computer" role Clients in the AD group "Medical" are assigned the "medical-staff" role Clients in the AD group "Reception" are assigned to the "reception-staff" role The customer requires CPPM to assign authenticated clients to AOS firewall roles as follows:
* Assign medical staff on mobile-onboarded clients to the "medical-mobile" firewall role
* Assign other mobile-onboarded clients to the "mobile-other" firewall role
* Assign medical staff on domain computers to the "medical-domain" firewall role
* All reception staff on domain computers to the "reception-domain" firewall role
* All domain computers with no valid user logged in to the "computer-only" firewall role
* Deny other clients access
# Other requirements
Communications between ClearPass servers and on-prem AD domain controllers must be encrypted.
# Network topology
For the network infrastructure, this customer has Aruba APs and Aruba gateways, which are managed by Central. APs use tunneled WLANs, which tunnel traffic to the gateway cluster. The customer also has AOS-CX switches that are not managed by Central at this point.
# ClearPass cluster IP addressing and hostnames
A customer's ClearPass cluster has these IP addresses:
* 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
The customer's DNS server has these entries
* cp.acnsxtest.com = 10.47.47.5
* cps1.acnsxtest.com = 10.47.47.6
* cps2.acnsxtest.com = 10.47.47.7
* radius.acnsxtest.com = 10.47.47.8
* onboard.acnsxtest.com = 10.47.47.8
You cannot see flow attributes for wireless clients.
What should you check?
- A. Gateway IDS/IPS is enabled on the Aruba gateways, and the gateways have been rebooted.
- B. Deep packet inspection is enabled on the role to which the Aruba APs assign the wireless clients.
- C. Firewall application visibility is enabled on the Aruba gateways, and the gateways have been rebooted.
- D. Deep packet inspection is enabled on the Aruba Aps, and the APs have been rebooted.
Several AOS-CX switches are responding to SNMPv2 GET requests for the public community. The customer only permits SNMPv3. You have asked a network admin to fix this problem. The admin says, "I tried to remove the community, but the CLI output an error." What should you recommend to remediate the vulnerability and meet the customer's requirements?
- A. Setting the snmp-server settings to "snmpv3-only"
- B. Enabling control plane policing to automatically drop SNMP GET requests
- C. Enabling SNMPv3, which implicitly disables SNMPv1/v2
- D. Adding an SNMP community with a long random name
Explanation: Only visible for Fast2test members. You can sign-up / login (it's free).
Refer to the scenario.
A customer has an Aruba ClearPass cluster. The customer has AOS-CX switches that implement 802.1X authentication to ClearPass Policy Manager (CPPM).
Switches are using local port-access policies.
The customer wants to start tunneling wired clients that pass user authentication only to an Aruba gateway cluster. The gateway cluster should assign these clients to the "eth-internet" role. The gateway should also handle assigning clients to their VLAN, which is VLAN 20.
The plan for the enforcement policy and profiles is shown below:
The gateway cluster has two gateways with these IP addresses:
* Gateway 1
o VLAN 4085 (system IP) = 10.20.4.21
o VLAN 20 (users) = 10.20.20.1
o VLAN 4094 (WAN) = 198.51.100.14
* Gateway 2
o VLAN 4085 (system IP) = 10.20.4.22
o VLAN 20 (users) = 10.20.20.2
o VLAN 4094 (WAN) = 198.51.100.12
* VRRP on VLAN 20 = 10.20.20.254
The customer requires high availability for the tunnels between the switches and the gateway cluster. If one gateway falls, the other gateway should take over its tunnels. Also, the switch should be able to discover the gateway cluster regardless of whether one of the gateways is in the cluster.
You are setting up the UBT zone on an AOS-CX switch.
Which IP addresses should you define in the zone?
- A. Primary controller = 10.20.4.21; backup controller = 10.20.4.22
- B. Primary controller = 10 20 4 21: backup controller not defined
- C. Primary controller = 10.20.20.254; backup controller, not defined
- D. [Primary controller = 198.51.100.14; backup controller = 10.20.4.21
Explanation: Only visible for Fast2test members. You can sign-up / login (it's free).
Refer to the scenario.
An organization wants the AOS-CX switch to trigger an alert if its RADIUS server (cp.acnsxtest.local) rejects an unusual number of client authentication requests per hour. After some discussions with other Aruba admins, you are still not sure how many rejections are usual or unusual. You expect that the value could be different on each switch.
You are helping the developer understand how to develop an NAE script for this use case.
You are helping the developer find the right URI for the monitor.
Refer to the exhibit.
You have used the REST API reference interface to submit a test call. The results are shown in the exhibit.
Which URI should you give to the developer?
- A. /rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics
- B. /rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics.access_rejec
- C. /rest/v1/system/vrfs/mgmt/radius/servers/cp.acnsxtest.local/2083/tcp?attributes=authstatistics?attributes=a
- D. /rest/v1/system/vrfs/mgmt/radius/_servers/cp.acnsxtest.local/2083/tcp
