What describes the use of the Network Analytics Engine?
Correct answer: C
The Network Analytics Engine is used for automated root cause analytics on AOS-CX switches. It is not primarily a scheduled backup tool, support case generator, or automatic tech-support file creator.
The customer requires the highest speed available using a single-port link between an HPE Aruba Networking CX 6200 and an HPE Aruba Networking CX 8100 over a distance of 3 meters, or 9 feet.
Which is the correct validated connectivity option for a single port?
Correct answer: A
For the stated CX 6200 to CX 8100 single-port connection over a short 3-meter distance, 10G-DAC is the validated option among the choices. The higher-speed DAC or optical options listed do not match the supported single-port compatibility in this scenario.
A customer requires a network upgrade to replace their existing core switches. The new solution must support 100G speeds to the aggregation layer and occupy a maximum physical space of 10U as a chassis solution.
Which HPE Aruba Networking CX switch model would you initially propose?
Correct answer: D
The CX 8400 is a chassis solution that matches a core-switch replacement needing 100G aggregation support while staying within the stated 10U space limit. The other listed platforms are fixed or specialized models that do not fit the requested chassis profile.
You have access to the CLI of an HPE Aruba Networking CX switch.
How can you output the switch make, model, and serial number displayed on the session?
Correct answer: D
The show system command displays platform identity information such as make, model, and serial number. show support-information is broader support output, show configuration displays configuration, and diagnostic dump commands are not the normal quick identity command.
Which is an example of half-duplex communication?
Correct answer: B
Push-to-talk radio is half-duplex because only one side transmits at a time while others listen. A telephone call is full-duplex, FM broadcast is one-way simplex, and a fiber pair can support simultaneous transmit and receive paths.
You are trying to verify that your HPE Aruba Networking CX switch has access to the local DNS server through the out-of-band management interface.
You have run the following ping command, but there has been no response:
ping 10.1.50.11
What would explain this?
Correct answer: B
The out-of-band management interface belongs to the management VRF. To test reachability through that interface, the ping must specify the mgmt VRF so the correct routing table and source interface are used.
Creating a new VRF or assuming ping is unsupported is not the right explanation.
You are about to log a support case with TAC for an issue with your HPE Aruba Networking CX switch.
What should you have ready in advance to provide them?
Correct answer: A
TAC commonly requests technical support output such as show tech because it collects device state, configuration, and diagnostic details needed for troubleshooting. Internet SSH access, firmware copies, or generated support keys are not the standard first item to prepare.
Which commands can ensure the current configuration persists after a reboot? Choose two.
Correct answers: B, E
write memory and copy running-config startup-config save the current running configuration so it persists after reboot. copy startup-config running-config moves in the opposite direction, and commit confirm or save force are not the standard AOS-CX persistence commands listed here.
A technician installed a new HPE Aruba Networking 580EX Series access point, which is cabled back to an HPE Aruba Networking CX 6000 48G 4SFP switch. However, there are no lights on the access point.
What could cause this issue?
Correct answer: B
An access point with no lights is consistent with a power problem. If the switch cannot supply sufficient
PoE budget per port, the AP may not power on at all. VLAN, STP, or Central connectivity issues can affect network service, but they do not normally leave the AP unpowered.
Which statement is true when creating VLANs on an HPE Aruba Networking CX switch?
Correct answer: B
AOS-CX supports VLAN range creation with hyphen syntax, such as vlan 100-110. Colon syntax is not the expected range form, and newly created VLANs do not require the listed enable or no shutdown commands in this context.
