Question 1

What is the recommended VSF topology? (Select two.)

AStar

BDaisy chain plus MAD

CFull mesh

DFull mesh plus MAD

ERing

Answer : B, E

Only: Daisy chain plus MAD and ring are the recommended VSF topologies for Aruba switches. They provide high availability and redundancy for the VSF stack. MAD (Multiple Active Detection) is a mechanism to detect and resolve split-brain scenarios in a VSF stack.

Question 2

Describe the purpose of the administrative distance

ARoutes teamed via external BGP have a higher administrative distance than routes learned via OSPF

BThe administrative distance is used as a trust rating For route entries

CThe administrative distance for a static route is 10

DThe higher administrative distance is preferred

Answer : B

The administrative distance is used as a trust rating for route entries (B). It is a metric used by routers to select the best path when there are two or more different routes to the same destination from two different routing protocols. The lower the administrative distance value, the more trustworthy the source of the route. For example, a directly connected network has an administrative distance of 0 because it is the most trusted source of routing information. In contrast, routes learned from different routing protocols have higher administrative distances, reflecting their relative trustworthiness.

Question 3

Which type of device type and group persona is required to manage a Microbranch environment?

AArubaOS 10 AP Group Persona

BArubaOS 10 Branch Gateway Group Persona

CArubaOS 8 AP Group Persona

DArubaOS 8 Branch Gateway Group Persona

Answer : B

In the context of Aruba networks, a Microbranch environment is managed using a group persona that aligns with the functionality required. ArubaOS 10 Branch Gateway Group Persona would be the correct device type and group persona for managing a Microbranch environment, as it would provide the necessary features and controls for branch networking requirements.

Question 4

A network technician is troubleshooting one new AP at a branch office that will not receive Its configuration from Aruba Central The other APs at the branch are working as expected The output of the 'show ap debug cloud-server command' shows that the "cloud conflg received" Is FALSE.

After confirming the new AP has internet access, what would you check next?

ADisable and enable activate to trigger provisioning refresh

BVerify the AP can ping the device on arubanetworks.com

CVerify the AP has a license assigned

DDisable and enable Aruba Central to trigger configuration refresh

Answer : A

When an Aruba AP is not receiving its configuration from Aruba Central, and other APs at the location are functioning normally, a common troubleshooting step is to disable and then re-enable the activation process on the AP. This action can trigger a provisioning refresh, prompting the AP to attempt to retrieve its configuration from Aruba Central again. This step is often effective in resolving communication or provisioning issues between the AP and the management platform.

Question 5

What does WPA3-Personal use as the source to generate a different Pairwise Master Key (PMK) each time a station connects to the wireless network?

ASession-specific information (MACs and nonces)

BOpportunistic Wireless Encryption (OWE)

CSimultaneous Authentication of Equals (SAE)

DKey Encryption Key (KEK)

Answer : C

WPA3-Personal enhances the security of wireless networks by using Simultaneous Authentication of Equals (SAE), which is a more secure replacement for the Pre-Shared Key (PSK) method used in WPA2. SAE strengthens the initial key exchange, providing better protection against offline dictionary attacks and ensuring that each session has a unique Pairwise Master Key (PMK), derived from the interaction between the client and the access point, including session-specific information like MAC addresses and nonces.

Question 6

After having configured the edge switch uplink as requested your colleague says that they have failed to ping the core You ask your colleague to verify the connection is plugged in and the switch is powered on They confirm that both are correct You attempt to ping the core switch and confirm that the ping is failing.

Knowing the nature of this deployment, what commands might you use to troubleshoot this issued

APing 10.11 1 - ping the core to attempt to verify connectivity Show trunk - to verify if the LAG interface was correctly added to the switch Show spanning tree - to check for spanning-tree blocked states Show port-access clients interface all - to view any port-access blocking states or failed authentication attempts on all interfaces Show run interface vlan20 - to double check the layer 3 svi configuration is correct for l_3 connectivity Show lldp neighors - to verify whether you are able to see the Core as an L2 neighbor to verify if the correct links are plugged in to the correct ports

Bdiagnostic diag cable-diag 1/1/51 diag cable-diag 1/1/52 - to view diagnostic information for the physical link to get a status on any interruptions to Layer 1 connectivity, show ip route - to verify that the default gateway is present in the routing table show ip ospf - to check whether there is a layer 3 routing protocol enabled show ip dns - to view whether there is a valid dns source

CPing 10.1.1.1 - ping the core to attempt to verify connectivity show lacp agg - to verify which link aggregations are currently configured using which physical ports show lacp int - to verify the LACP status and whether any links are blocking in your topology show lldp neighors - to verify whether you are able to see the Core as an L2 neighbor to verify if the correct links are plugged in to the correct ports show run interface 1/1/51.1/1/52-to ensure the physical interfaces are no-shut and members of the lag show run interface lag 1 - to ensure the correct vlan trunking configuration is applied to the logical interface show run int vlan 20 - to ensure you have the L3 SVI no shut and configured in the correct subnet

DShow run - to view the running configuration of the switch Show run | begin 20 'vlan 20' - to ensure VLAN 20 was correctly added to the database show run | begin 20 'interface vlan 20' - to view the L3 SVI configuration Show run interface 1/1/51.1/1/52 - to ensure the physical interfaces are no shut and were added as members of LAG 1 Show run int lag 1 - to verify LACP mode active was configured to eliminate LACP blocking states

Answer : C

These commands might help troubleshoot this issue as they check various aspects of the connectivity between the edge switch and the core switch, such as Layer 3 reachability, Layer 2 adjacency, LACP configuration and status, VLAN trunking configuration, and interface status.

Question 7

The customer has a requirement to create authorization policies for their users with Windows 10 clients, with a requirement Tor authorizing both device and user credentials within one Radius session.

What would be the correct solution for the requirement?

AClearPass 6.9 with EAP-TTLS

BClearPass 6.9 with EAP-TLS

CClearPass 6.9 with PEAP

DClearPass 6.9 with EAP-TEAP

Answer : D

EAP-TEAP is a tunnel-based authentication method that supports both device and user authentication within a single RADIUS session. ClearPass 6.9 supports EAP-TEAP as an authentication method for Windows 10 clients. Reference: https://www.arubanetworks.com/techdocs/ClearPass/6.9/Guest/Content/CPPM_UserGuide/EAP-TEAP/EAP-TEAP.htm

For the requirement to authorize both device and user credentials within one Radius session, the correct solution would be ClearPass 6.9 with EAP-TEAP (EAP-Tunneled Extensible Authentication Protocol). EAP-TEAP is a tunneling protocol that creates a secure communication channel between the client and the server, allowing for the transmission of multiple authentication transactions within a single session. This capability is particularly useful in scenarios where both user and device credentials need to be verified before granting access to network resources, providing an additional layer of security and ensuring that both the user and the device are authorized to access the network.
