정답:

Question No : 2

You are configuring gateway IDS/IPS settings in Aruba Central.
For which reason would you set the Fail Strategy to Bypass?

A.To permit traffic if the IPS engine falls to inspect It
B.To enable the gateway to honor the allowlist settings configured in IDS/IPS policies
C.To tell gateways to stop enforcing IDS/IPS policies if they lose connectivity to the Internet
D.To avoid wasting IPS engine resources on filtering traffic for unauthenticated clients

Question No : 3

Refer to the scenario.
A customer is migrating from on-prem AD to Azure AD as its sole domain solution. The customer also manages both wired and wireless devices with Microsoft Endpoint Manager (Intune).
The customer wants to improve security for the network edge. You are helping the customer design a ClearPass deployment for this purpose. Aruba network devices will authenticate wireless and wired clients to an Aruba ClearPass Policy Manager (CPPM) cluster (which uses version 6.10).
The customer has several requirements for authentication. The clients should only pass EAP-TLS authentication if a query to Azure AD shows that they have accounts in Azure AD. To further refine the clients’ privileges, ClearPass also should use information collected by Intune to make access control decisions.
You are planning to use Azure AD as the authentication source in 802.1X services.
What should you make sure that the customer understands is required?

A.An app registration on Azure AD that references the CPPM's FQDN
B.Windows 365 subscriptions
C.CPPM's RADIUS certificate was imported as trusted in the Azure AD directory
D.Azure AD Domain Services

The customer wants you to configure CPPM to collect information from Intune on demand during the authentication process.
What should you tell the Intune admins about the certificates issued to clients?
A. They must be issued by a well-known, trusted CA.
B. They must include the Intune ID in the subject name.
C. They must include the client MAC address in the subject name.
D. They must be issued by a ClearPass Onboard CA.

정답: A

Question No : 5

A customer requires a secure solution for connecting remote users to the corporate main site. You are designing a client-to-site virtual private network (VPN) based on Aruba VIA and Aruba Mobility Controllers acting as VPN Concentrators (VPNCs). Remote users will first use the VIA client to contact the VPNCs and obtain connection settings.
The users should only be allowed to receive the settings if they are the customer's “Remote Employees” AD group. After receiving the settings, the VIA clients will automatically establish VPN connections, authenticating to CPPM with certificates.
What should you do to help ensure that only authorized users obtain VIA connection settings?

A.Set up the VPNCs' VIA web authentication profile to use CPPM as the authentication server; set up a service on CPPM that uses AD as the authentication source.
B.Set up the VPNCs' VIA web authentication profile to use an AD domain controller as the LDAP server.
C.Set up the VPNCs' VIA connection profile to use two authentication profiles, one RADIUS profile to CPPM and one LDAP profile to A
D.Set up the VPNCs' VIA connection profile to use one authentication profile, which is set to the AD domain controller's hostname.

Question No : 6

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.Apply the “apprf-medical-mobile-sacl" policy explicitly to the “medical-mobile” user-role under the “medical-mobile” policy.
B.In the “medical-mobile” policy, change the action for rules 2 and 3 to reject.
C.In the “medical-mobile” policy, move rule 5 under rule 6.
D.In the “medical-mobile” policy, change the subnet mask in rule 5 to 255.255.252.0.

Question No : 7

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 are using the “myzone” name for the UBT zone.
Which is a valid minimal configuration for the AOS-CX port-access roles?

A.port-access role eth-internet gateway-zone zone myzone gateway-role eth-user
B.port-access role internet-only gateway-zone zone myzone gateway-role eth-internet
C.port-access role eth-internet gateway-zone zone myzone gateway-role eth-internet vlan access 20
D.port-access role internet-only gateway-zone zone myzone gateway-role eth-internet vlan access 20
