Your customer asked for help to apply an ACL for wireless guest users with the following criteria:
· Wi-Fi guests are on VLAN 555
· allow internet access
· only allow access to public DNS servers
· deny access to all internal networks except for any DHCP server These session ACLs are already present in the CLI of the mobility gateway group:



You have access to the CLl.
Which user role meets all the criteria?









Answer(s): A

Explanation:

Based on the criteria provided for wireless guest users, the correct user role configuration must allow internet access, only allow access to public DNS servers, deny access to all internal networks except for any DHCP server, and place the Wi-Fi guests on VLAN 555. The ACLs must permit services necessary for basic internet access (such as DNS and DHCP) and block access to internal networks. Option A satisfies these criteria with the following configurations:
user-role "WiFi-guest": This defines the role for Wi-Fi guests. access-list session dhcp-acl: This applies the access list that likely permits DHCP, which is necessary for guests to obtain an IP address.
access-list session dns-acl: This applies the DNS access list, which likely restricts guests to using public DNS servers.
access-list session internal-networks: This applies the internal networks access list, which denies access to internal networks.

vlan 555: This sets the VLAN for Wi-Fi guests to 555.
Options B, C, and D are incorrect because they include access-list session allowall which would permit all traffic, contradicting the requirement to deny access to all internal networks.



Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?

  1. packet-capture datapath udp 3799
  2. packet-capture controipath udp 3799
  3. packet-capture interprocess udp 3799
  4. tcpdump host-port 3799

Answer(s): B

Explanation:

The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.
Option B, packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.
Options A, C, and D are incorrect because:
Option A captures data plane traffic, not control plane traffic. Option C's packet-capture interprocess udp 3799 does not refer to a standard command for capturing CoA messages.
Option D, tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.



The ACME company has an AOS-CX 6200 switch stack with an uplink oversubscription ratio of 9.6:1. They are considering adding two more nodes to the stack without adding any additional uplinks due to cabling constraints One of their architects has expressed concerns that their critical UDP traffic from both wired and bridged AP clients will encounter packet drops. They have already applied the following configuration:







Which strategy will complement this solution to achieve their objective?

  1. edge mark lower priority TCP traffic with AF12
  2. edge mark critical UDP Traffic with CSS
  3. edge mark lower priority TCP traffic with AF11
  4. edge mark critical UDP traffic with AF42

Answer(s): D

Explanation:

Given that the ACME company's concern is about UDP traffic potentially encountering packet drops due to uplink oversubscription, they need a strategy that prioritizes critical UDP traffic to minimize loss.
Option D, edge mark critical UDP traffic with AF42, is the correct answer. Assured Forwarding (AF) classes provide a way to assign different levels of delivery assurance for IP packets. AF42 is typically used for traffic that requires low latency and low loss, such as voice and video, which often use UDP. Marking critical UDP traffic with AF42 will help ensure that this traffic is treated with higher priority over the network.
Option A (edge mark lower priority TCP traffic with AF12) and Option C (edge mark lower priority TCP traffic with AF11) suggest marking lower priority TCP traffic, which does not directly address the concern for critical UDP traffic.
Option B (edge mark critical UDP Traffic with CS5) suggests using Class Selector 5 for critical UDP traffic, which is also a valid approach but does not match the existing configuration that is focused on Assured Forwarding (AF) classes.

An administrator is creating a fabric with NetConductor in HPE Aruba Networking Central Considering an EVPN VXLAN fabric, click on the most appropriate layer to be configured as a Rome- Reflector Persona.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at the Services Aggregation layer. This layer is responsible for interconnecting different network services and typically includes more robust, higher-capacity devices capable of handling the route-reflection functions for EVPN VXLAN.
In an Aruba Networks fabric, route reflectors are used to optimize the distribution of BGP routes. The Services Aggregation layer, which is centrally located in the network topology, is best suited for this role due to its high availability and ability to efficiently manage routes between the core and access layers.
Therefore, if you were to click on the image provided, you would select the Services Aggregation layer to configure the Route-Reflector Persona.
