HPE Network Switching Associate Exam Sample Questions (Q34-Q39):

NEW QUESTION # 34
Which commands can ensure the current configuration persists after a reboot? (Choose two.)

Answer: A,B

Explanation:
These commands save the active running configuration to persistent storage so it is retained after a reboot. Writing the configuration to startup storage ensures the switch reloads the same configuration when it restarts.


NEW QUESTION # 35
When might a switch add a VLAN tag to a frame?

Answer: A


NEW QUESTION # 36
Users report poor performance when uploading files to their document management server in the same subnet.
You suspect packet loss is causing the problem.
Which tool in HPE Aruba Networking Central can you use to confirm this?

Answer: A

Explanation:
The correct answer is C. Commands - show interface error-statistics. Because the users and the document management server are in the same subnet, traffic is switched locally rather than routed across multiple Layer
3 hops. If packet loss is suspected during file uploads, the most useful verification is to inspect interface error counters on the switch ports involved. HPE Aruba Networking AOS-CX documentation includes the show interface < IFNAME > error-statistics command, which displays interface error statistics such as receive and transmit errors, CRC/FCS errors, drops, runts, giants, and related counters. HPE Aruba Networking Central documentation states that the Commands tab can run troubleshooting commands on managed devices and show the output in the Device Output section. A cable test may help detect physical cabling faults, but it does not directly confirm packet loss counters. Traceroute is less useful within the same subnet. Ping can show reachability loss, but interface error statistics provide better evidence of switch-port packet errors causing performance problems.


NEW QUESTION # 37
Your colleague is installing a new HPE Aruba Networking CX 8100 switch in a data center in the default configuration. You monitor the peer switch port 1/1/1 status, connected with a 10Gb 3m DAC cable to the new switch, and validate that the cable is attached. The port remains down.
What should you suggest your colleague do so the port can come online?

Answer: C

Explanation:
On HPE Aruba Networking CX switches, physical interfaces are administratively disabled by default. Issuing the no shutdown command on the interface enables the port, allowing the link to come online when a valid connection is present.


NEW QUESTION # 38
Drag and Drop Question
You are troubleshooting a connectivity issue and are reviewing your notes after talking to your team. Classify each piece of information as either a symptom or a possible cause. (Matches may be used more than once.)

Answer:

Explanation:

Explanation:
A symptom is an observed problem experienced by users or systems. A cause is a change, condition, or failure that could plausibly explain those observed problems.
