The CLI output displays EVPN routes and their corresponding next hops. The "Route Distinguisher" entries
followed by IP addresses in the 172.21.11.x range indicate these are loopback addresses used by the underlay
network. The underlay network provides the basic routing and forwarding plane for the overlay network that
EVPN is part of. These loopback addresses are crucial for the proper functioning of the EVPN control plane.
Question #:2
A customer has deployed anAOS 10 mobilitygateway cluster consisting of three controllers at a single site The
WLAN is configured to tunnel wireless device traffic to the AOS 10 mobilitycluster.The clients areauthorized
to use WPA2-Personal.An end-userhas opened a ticket with the helpdesk stating they cannot connect their
client device to the network.There are other devices currently associated with the SSID with no issues.
Reviewing the output, what Is the issue?
The RADIUS response from the authentication server is
The client device has an invalid certificate
The client device has an invalid pre-shared key.
transition mode is not enabled
Answer: C
Explanation
The issue indicated by the output is an invalid pre-shared key (PSK). The logs show multiple failures during
the WPA2 key exchange process, which points to a mismatch between the PSK configured on the client device
and the PSK expected by the AOS 10 mobility gateway.
Question #:3

What is needed to resolve this issue?
Enable authorization in your Authentication Method.
Recreate the SSID m tunneled mode.
Modify your ACX-AD authentication source to include the UPN in the search.
Configure ClearPass to trust the client certificate.
Answer: C
Explanation
The error message "User not found" indicates that the authentication source, in this case, Active Directory
(AD), is not able to locate the user account based on the current search parameters. This often occurs when the
User Principal Name (UPN) that the client is using to authenticate is not included in the search parameters of
the AD authentication source within ClearPass. By modifying the AD authentication source to include the
UPN in the search, ClearPass will be able to correctly locate the user account and proceed with the
authentication using the valid client certificates.
Question #:4
An administrator is creating a fabric withNetConductor in HPE Aruba Networking Central Considering an
EVPN VXLAN fabric, click on the most appropriate layer to be configured as a Rome-Reflector Persona.
HP - HPE7-A07Pass Exam
4 of 12Verified Solution - 100% Result
A. 
B. 
Answer:
Explanation
In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at
theServices Aggregationlayer. 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.
Question #:5
A customer’s infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile
cased on best practices. Why do they have an equal split of their 120 APs across the primary and secondary
gateway clusters?
The primary gateway cluster is a heterogeneous cluster with six nodes.

The primary and secondary gateway clusters are up. and the cluster preemption is enabled
The secondary gateway cluster is a homogeneous cluster with six nodes.
The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled
Answer: D
Explanation
When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary
gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split
of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no
automatic rebalancing of APs back to the primary cluster, leading to the current distribution.

A university runs its own TV station in the city The IT department deploys a multimedia server so the TV
productions can be sent out to the entire campus over the IP network using multicast-based communications in
order to improve the bandwidth consumption. PlM sparse Mode and IGMP snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor
network performance. However, wired users are not affected in this way While troubleshooting the network
administrator saves the packet captures shown in the exhibit and concludes that all users even those not joining
the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
Dynamic Multicast Optimization and Multicast Transmission Optimization
UCC QoS correction and Multicast Transmission Optimization
ARP broadcast conversion into unicast and Multicast Transmission Optimization
Dynamic Multicast Optimization and UCC QoS correction
Answer: A
Explanation
Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help
address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is
transmitted over the air by converting multicast streams into unicast streams tothe clients that need them. This
reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall
network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames

to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds
by all users.
Question #:8
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:

Option A
Option B
Option C
Option D
Answer: 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 which would permit allaccess-list session allowall
traffic, contradicting the requirement to deny access to all internal networks.

Which statement is true given the following CLI output from a CX 6300?
There are no active fabric clients on the CX switch with RD 172.16.10.1
A wired client with IP address 10.203 1.100 is on a remote CX 6300 in the fabric with loopback IP
address 172.21.11.2.
A wired client with IP address 10 203 1 100 has a host route that is not being properly advertised
The overlay loopbacK addresses are advertised in the faerie with 2d-bit subnet masks
Answer: B
Explanation
The CLI output provided shows routing information from a CX 6300 switch. The output under "VRF: default"
shows various IP routes, including a route for 10.203.1.100/32 with a next hop of 172.21.11.2. This indicates
that the route to the client with IP address 10.203.1.100 is known in the network and is reachable via another
device in the fabric, which has the loopback IP address 172.21.11.2. Since the route is present in the routing
table, it means that the client is known and active within the fabric network.

A network administrator attempts to improve multicast traffic flow and performs some packet captures for
validation What can the network administrator conclude from the results?
The data rate increased from 6 Mops to 300 Mops because Broadcast Multicast optimization (BCMCO)
was configured.
The capture taken after optimization does not show a packet length because Multicast Transmission

Optimization was configured.
The type flew remains consistent because Dynamic Multicast Optimization (DMO) was configured.
The data rate increased from 6 Mbps to 300 Mops because Dynamic Multicast Optimization (DMO) was
configured.
Answer: D
Explanation
Dynamic Multicast Optimization (DMO) is a feature that enhances the delivery of multicast traffic by
optimizing the data rate. The before and after optimization images show a significant increase in the data rate,
which is a typical result of DMO being configured, as it allows multicast traffic to be transmitted at higher
data rates by converting multicast streams into unicast streams for the clients that need them.
