ACSP Network Monitoring and Management 5 — Questions and Answers
Question 1: Which Aruba tool provides a topology map and historical performance data for switches managed in a campus network?
- Aruba NetEdit
- Aruba Central (Correct answer)
- Aruba ClearPass
- Aruba AirMatch
Correct answer: Aruba Central
Aruba Central provides topology visualization, historical performance trending, and centralized management for campus switches and wireless infrastructure.
Question 2: When configuring SNMPv3 on an Aruba switch, which two parameters uniquely identify a user for authentication?
- Community string and OID
- Username and engine ID (Correct answer)
- IP address and UDP port
- MIB tree and security model
Correct 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.
Question 3: 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?
- logging buffered 7days
- logging buffer duration 7
- logging buffered severity informational count 10000 (Correct answer)
- logging local retention 7
Correct 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.
Question 4: Which SNMP operation does a management station use to retrieve a series of consecutive MIB variables from a switch?
- SNMP Get
- SNMP GetBulk (Correct answer)
- SNMP Set
- SNMP Inform
Correct answer: SNMP GetBulk
GetBulk retrieves multiple MIB variables in a single request, making it more efficient than issuing repeated GetNext operations for table data.
Question 5: A network operations team wants to receive immediate notification when a switch's power supply fails. Which configuration should be implemented?
- SNMP polling of the entity MIB every 5 seconds
- SNMP trap or inform for the cefcFRURemoved or similar power supply OID (Correct answer)
- Syslog severity 6 (informational) forwarding
- Spanning tree topology change notification only
Correct 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.
Question 6: On an ArubaOS-CX switch, which REST API method is used to retrieve the current running configuration?
- POST /rest/v10.08/system/config/running
- GET /rest/v10.08/system?depth=2 (Correct answer)
- PUT /rest/v10.08/system/full-configuration
- PATCH /rest/v10.08/system/config
Correct 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.
Question 7: What is the primary difference between SNMP traps and SNMP informs?
- Traps use TCP while informs use UDP
- Informs require an acknowledgment from the receiver; traps do not (Correct answer)
- Traps support SNMPv3 encryption; informs do not
- Informs can only be sent to one destination; traps support multiple
Correct 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.
