Which Aruba tool provides a topology map and historical performance data for switches managed in a campus network?
Answer: Aruba Central
Aruba Central provides topology visualization, historical performance trending, and centralized management for campus switches and wireless infrastructure.
When configuring SNMPv3 on an Aruba switch, which two parameters uniquely identify a user for authentication?
Answer: Username and engine ID
In SNMPv3, the combination of username and the authoritative engine ID uniquely identifies a user and prevents replay attacks across different SNMP engines.
An ArubaOS-CX switch is sending event logs to a syslog server. The administrator wants to also store them locally for 7 days. Which configuration achieves this?
Answer: logging buffered severity informational count 10000
Configuring 'logging buffered' with a severity level and buffer count stores messages locally in RAM; the retention duration depends on log volume and buffer size.
Which SNMP operation does a management station use to retrieve a series of consecutive MIB variables from a switch?
Answer: SNMP GetBulk
GetBulk retrieves multiple MIB variables in a single request, making it more efficient than issuing repeated GetNext operations for table data.
A network operations team wants to receive immediate notification when a switch's power supply fails. Which configuration should be implemented?
Answer: SNMP trap or inform for the cefcFRURemoved or similar power supply OID
Configuring SNMP traps or informs for power supply events ensures immediate notification when a power supply is removed or fails, without the delay of polling.
On an ArubaOS-CX switch, which REST API method is used to retrieve the current running configuration?
Answer: GET /rest/v10.08/system?depth=2
A GET request to the system endpoint with appropriate depth parameter retrieves the current running configuration via the ArubaOS-CX REST API.
What is the primary difference between SNMP traps and SNMP informs?
Answer: Informs require an acknowledgment from the receiver; traps do not
SNMP informs are acknowledged by the receiving NMS, providing delivery confirmation; traps are unacknowledged fire-and-forget messages.
