An OSPF router has learned a path to an external network by both an E1 and E2 advertisement, both routes having the same path cost.
Which path will the router prefer?
ABoth routes will be suppressed until the path conflict has been resolved.
BThe router will use both paths equally my means of ECMP.
CThe router will prefer the E1 path.

You are configuring an SSID that is using 802.1X as a security mechanism. What is the reason for using WPA3-Enterprise (CCM-128) when deploying Wi-Fi 6 networks?
AWPA3-Enterprise (CCM-128) is also called WPA3-Enterprise Transition Mode. It will allow WPA2 clients to connect.
BWPA3-Enterprise (CCM-128) is also called WPA3-Enterprise Compatibility Mode. It will allow WPA2 clients to connect.
CWPA3-Enterprise (CCM-128) is also called WPA3-Enterprise Only Mode. There is no support for WPA2 clients.
DWPA3-Enterprise (CCM-128) is also called WPA3-Enterprise 192-bit mode. It is WPA3 only and enforces specific EAP certificate ciphers.

An IT administrator wants to set up an HPE Aruba Networking User Experience Insight (UXI) sensor. During the initiation process, the administrator sees that the color of the LED is orange.
What does the orange LED mean?
AThe sensor needs multi-rate port but this port is only standard 1G port
BThe sensor is still booting
CThe sensor cannot connect to the UXI cloud
DThis is a G6E UXI sensor and does not have enough PoE power
A hospital is using a multicast configuration on its network in a separate VLAN for the televisions in each room. Which feature prevents unwanted multicast on switches where it is not needed?
AIGMP snooping
BIGMP static-group
CIGMP disabled on unneeded switches
DIGMP protocol
What is the best practice for using Dynamic Segmentation?
AUse UBT to create isolated networks for specific types of devices.
BUse a combination of role-based access and overlay technologies to create a layered security approach
CUse LUR to assign roles to devices based on their location and DUR to assign roles to devices based on their user identity.
DUse Dynamic Segmentation only on devices that are connected to the network via Wi-Fi.
A client installed 655 APs in a project to upgrade the network in a large public venue. The customer states that they are having issues with the integration with the new sensor system (Bluetooth) that will help the facilities team monitor when the venue is in the use.
What could be the issue?
AAP-655 does not have Bluetooth radio
Bthroughput
CPoE
DBluetooth needs an advanced AP license.
Which tables are synchronized between a pair of CX 10000 switches in a VSX cluster? (Choose two.)
Alink Layer Discovery Protocol (LLDP)
BDynamic Host Control Protocol (DHCP)
CAddress Resolution Protocol (ARP)
DIP Routing
EBGP Neighbors
A network administrator wants to collect dumps for traffic sources or destined to a specific IP address. What is the simplest diagnostic command or commands on AOS-CX switches to accomplish this?
A gateway cluster with AOS-10 is managed by HPE Aruba Networking Central. In a failover, what is the expected behavior of the client traffic?
AClient traffic is disrupted during the AP bootstrap.
BClient state synchronization is supported on each failover.
CClient IPv4 multicast session failover is not supported.
DClient state synchronization is supported on the first failover.
An administrator is monitoring third-party WLAN transmitters in HPE Aruba Networking Central and some of them are classified as rogue and suspected rogue.
How are suspected rogues classified when using the default classification method for the rule “Suspected AP On-Prem” in HPE Aruba Networking Central?
Asignal level = “-65 dbM” AND WLAN classification = “On-Prem”
Bsignal level = “-65 dbM” AND WLAN classification = “On-Interfering”
Csignal level = “-50 dbM” AND WLAN classification = “On-Interfering”
Which issue may be causing the new door locks on the APs to not work?
AAT power to the AP is too much.
BBT power to the AP is too much.
CAF power to the AP is not enough.
DAT power to the AP is not enough.
Ever since a recent firewall change at your WAN/Internet edge, the BGP state in your VSX pair has not returned to Established.
What should you check to restore BGP functionality at this site?

CRestart NAT service for the BGP interface.
DConfirm that BGP Peer AS has not changed.
