Common Questions About the HP HPE6-A84 Exam
The HPE6-A84 exam is the official HP exam behind HP Aruba Certified Network Security Expert Written — passing it earns you the HP ACA - Network Security certification, a credential positioned at the Expert level. It is built for candidates who want to validate the skills measured by HP Aruba Certified Network Security Expert Written. Depending on your track, the exam is also linked to the Aruba Certified Network Security Expert (ACNSE) certification, so one pass can move you toward more than one HP credential.
The HPE6-A84 exam presents 60 questions to be completed within 120 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.
Strong knowledge of Aruba networking and security solutions is recommended. Prior Aruba professional-level certifications and hands-on deployment experience are highly recommended. Because HP revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official HP exam page before you register.

HP Aruba Certified Network Security Expert Written Sample Questions:
A customer has an AOS 10 architecture, which includes Aruba APs. Admins have recently enabled WIDS at the high level. They also enabled alerts and email notifications for several events, as shown in the exhibit.
Admins are complaining that they are getting so many emails that they have to ignore them, so they are going to turn off all notifications.
What is one step you could recommend trying first?
- A. Disable just the Rogue AP and Client Attack Detected alerts, as they overlap with the Infrastructure Attack Detected alert.
- B. Send the email notifications directly to a specific folder, and only check the folder once a week.
- C. Change the WIDS level to custom, and enable only the checks most likely to indicate real threats.
- D. Disable email notifications for Roque AP, but leave the Infrastructure Attack Detected and Client Attack Detected notifications on.
Explanation: Only visible for TestSimulate 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 have created a role mapping policy as shown in the exhibits below.
What is one change that you need to make to this policy?
- A. Move rules 2 and 3 to the top of the list.
- B. Change the rules evaluation mechanism to first applicable.
- C. Change the default role to 'mobile-onboarded*
- D. In rule 1 change Subject-CN to Issuer-CN.
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.
Assume that you have configured the correct UBT zone and port-access role settings. However, the solution is not working.
What else should you make sure to do?
- A. Create a new VLAN on the AOS-CX switch and configure that VLAN as the UBT client VLAN.
- B. Assign sufficient VIA licenses to the gateways based on the number of wired clients that will connect.
- C. Assign VLAN 20 as the access VLAN on any edge ports to which tunneled clients might connect.
- D. Change the port-access auth-mode mode to client-mode on any edge ports to which tunneled clients might connect.

Refer to the scenario.
A customer requires these rights for clients in the "medical-mobile" AOS firewall role on Aruba Mobility Controllers (MCs):
Permitted to receive IP addresses with DHCP
* Permitted access to DNS services from 10.8.9.7 and no other server
* Permitted access to all subnets in the 10.1.0.0/16 range except denied access to 10.1.12.0/22
* Denied access to other 10.0.0.0/8 subnets
* Permitted access to the Internet
* Denied access to the WLAN for a period of time if they send any SSH traffic
* Denied access to the WLAN for a period of time if they send any Telnet traffic
* Denied access to all high-risk websites
External devices should not be permitted to initiate sessions with "medical-mobile" clients, only send return traffic.
The line below shows the effective configuration for the role.
There are multiple issues with this configuration. What is one change you must make to meet the scenario requirements? (In the options, rules in a policy are referenced from top to bottom. For example,
"medical-mobile" rule 1 is "ipv4 any any svc-dhcp permit," and rule 6 is "ipv4 any any any permit'.)
- A. In the "medical-mobile" policy, move rule 5 under rule 6.
- B. Apply the "apprf-medical-mobile-sjcT policy explicitly to the 'medical-mobile' user-role under the
'medical-mobile" policy. - C. In the "medical-mobile" policy, change the action for rules 2 and 3 to reject.
- D. In the "medical-mobile* policy, change the subnet mask in rule 5 to 255.255.252.0.

Refer to the exhibit.
A customer requires protection against ARP poisoning in VLAN 4. Below are listed all settings for VLAN 4 and the VLAN 4 associated physical interfaces on the AOS-CX access layer switch:
What is one issue with this configuration?
- A. Edge ports are not configured as untrusted for ARP inspection.
- B. ARP proxy is not enabled on VLAN 4.
- C. LAG 1 is configured as trusted for ARP inspection but should be untrusted.
- D. DHCP snooping is not enabled on VLAN 4.
