NEW QUESTION # 139
Refer to the exhibit.
You have verified that AOS-CX Switch-1 has constructed an IP-to-MAC binding table in VLANs 10-19.
Now you need to enable ARP inspection for the endpoint connected to Switch-1. What must you do first to prevent traffic disruption?
Answer: B
Explanation:
Dynamic ARP Inspection (DAI):
ARP inspection verifies ARP packets against a trusted IP-to-MAC binding table to prevent ARP spoofing attacks.
DHCP snooping is required to construct the IP-to-MAC binding table dynamically.
To avoid traffic disruption, uplink ports that connect to trusted switches, DHCP servers, or routers must be explicitly configured as trusted ports for ARP inspection.
Steps to Prevent Traffic Disruption:
Trust the Uplinks: ARP inspection must treat uplink ports as trusted to allow ARP traffic from legitimate DHCP servers and upstream switches.
Enable DHCP Snooping: DHCP snooping must be enabled on Switch-2 to ensure consistent IP-to-MAC bindings upstream.
Why the Answer is Correct:
Option A: Incorrect. ARP inspection on Switch-2 is important but not required first to prevent disruption on Switch-1.
Option B: Incorrect. DHCP snooping must be enabled upstream eventually, but this alone will not stop immediate traffic disruption on Switch-1.
Option C: Correct. Switch-1 uplinks must be trusted ARP inspection ports first to allow legitimate upstream traffic and prevent ARP disruption.
Option D: Incorrect. Static bindings are not required if DHCP snooping is enabled, and they are manual, limiting scalability.
Conclusion:
To avoid traffic disruption, configure Switch-1 uplinks as trusted ARP inspection ports to ensure valid ARP traffic can pass upstream and downstream.
NEW QUESTION # 140
You have configured an AOS-CX switch to implement 802.1X on edge ports. Assume ports operate in the default auth-mode. VolP phones are assigned to the
"voice" role and need to send traffic that is tagged for VLAN 12.
Where should you configure VLAN 12?
Answer: C
Explanation:
When configuring 802.1X authentication on edge ports of an AOS-CX switch and assigning VoIP phones to a
"voice" role, the correct approach is to configure VLAN 12 as the allowed trunk VLAN in the "voice" role.
This setup ensures that traffic tagged for VLAN 12 is appropriately managed by the role applied to the VoIP phones. In AOS-CX switches, the role-based VLAN configuration allows for more granular control and ensures that the VoIP phones' traffic is handled correctly without altering the edge port settings, which typically operate with default settings for authentication.
Reference: Detailed configuration and role assignment practices for AOS-CX switches can be found in Aruba's configuration guides and documentation related to AOS-CX switch deployments.
NEW QUESTION # 141
An admin has configured an AOS-CX switch with these settings:
port-access role employees
vlan access name employees
This switch is also configured with CPPM as its RADIUS server.
Which enforcement profile should you configure on CPPM to work with this configuration?
Answer: B
Explanation:
To ensure that the AOS-CX switch properly assigns the "employees" role when using CPPM (ClearPass Policy Manager) as the RADIUS server, you should configure a RADIUS Enforcement profile on CPPM with the Aruba-User-Role VSA (Vendor-Specific Attribute) set to "employees". This configuration ensures that when an endpoint authenticates, CPPM sends the appropriate role assignment to the AOS-CX switch, which then applies the corresponding policies and VLAN settings defined for the "employees" role.
NEW QUESTION # 142
You have enabled "rogue AP containment" in the Wireless IPS settings for a company's HPE Aruba Networking APs. What form of containment does HPE Aruba Networking recommend?
Answer: C
NEW QUESTION # 143
Refer to the exhibit:
The exhibit shows the TACACS+ enforcement profile that HPE Aruba Networking ClearPass Policy Manager (CPPM) assigns to a manager. When this manager logs into an AOS-CX switch, what does the switch do?
Answer: D
Explanation:
* TACACS+ Enforcement Profile:
* The profile specifies a Service Attribute under Aruba:Common with:
* Name: Aruba-Admin-Role
* Value: operators
* AOS-CX Role Mapping:
* On Aruba AOS-CX switches, the Aruba-Admin-Role attribute maps the authenticated user to predefined roles:
* operators: Operator-level privileges (read-only access, limited commands).
* administrators: Full administrator privileges.
* Other roles like auditors may exist based on configuration.
* Analysis:
* The value operators explicitly maps the user to operator-level privileges, granting read-only access to the AOS-CX switch.
* Since the Aruba-Admin-Role is correctly set and recognized, the switch assigns the appropriate role without errors.
* Option Breakdown:
* Option A: Correct. The switch assigns operator-level privileges based on the Aruba-Admin-Role value.
* Option B: Incorrect. Administrator-level privileges require the role value to be administrators.
* Option C: Incorrect. The manager is successfully authenticated and authorized; there is no error.
* Option D: Incorrect. There is no reference to an auditor role in the configuration shown.
Conclusion:
The operators value in the TACACS+ enforcement profile ensures that the manager is assigned operator-level privileges on the AOS-CX switch.
