ACSP - Aruba Certified Switching Professional Network Monitoring and Management Questions and Answers

Question 1

A network administrator needs to implement a monitoring solution on an Aruba CX core switch to analyze traffic patterns and identify top talkers. The solution must have minimal impact on the switch's CPU. Which technology is most suitable for this requirement?

Accepted Answer

sFlow

Answer

sFlow is a packet sampling technology designed for high-speed networks. It statistically samples packets and sends the samples to a collector, providing visibility into traffic patterns with very low CPU overhead on the switch. Port Mirroring copies every packet, which can be resource-intensive. SNMP is for polling device status and metrics, not deep traffic analysis. Syslog is for event messages.

Question 2

An IT department uses Aruba NetEdit to manage its fleet of ArubaOS-CX switches. What is a primary function of Aruba NetEdit?

Accepted Answer

Orchestrating multi-switch configuration changes with validation and auditing.

Answer

Aruba NetEdit is a network management platform designed to simplify and automate the configuration, validation, deployment, and auditing of ArubaOS-CX switches. It allows administrators to orchestrate changes across multiple devices, validate configurations for consistency, and maintain an audit trail.

Question 3

A security policy requires that all SNMP traffic to and from Aruba CX switches must be authenticated to verify the source and encrypted to protect the data in transit. Which SNMP version and security level MUST be configured?

Accepted Answer

SNMPv3 with authPriv

Answer

SNMPv3 is the only version that supports strong authentication and encryption. The 'authPriv' (Authentication and Privacy) security level ensures that messages are both authenticated (using MD5 or SHA) and encrypted (using DES or AES), meeting the stated security requirements. 'authNoPriv' only provides authentication, and 'noAuthNoPriv' provides neither.

Question 4

An administrator is troubleshooting a fiber optic link and needs to check the health of the SFP+ transceiver, including its real-time transmit (Tx) power and receive (Rx) power levels. Which ArubaOS-CX feature provides this information?

Accepted Answer

Digital Optical Monitoring (DOM)

Answer

Digital Optical Monitoring (DOM), also known as Digital Diagnostic Monitoring (DDM), is a feature in optical transceivers that allows for real-time monitoring of key parameters such as optical Tx power, optical Rx power, temperature, and supply voltage. This is the correct tool for checking the physical health of a fiber link at the transceiver level.

Question 5

A network engineer wants to proactively monitor an Aruba CX switch for intermittent high CPU utilization. When the CPU exceeds 80% for more than five minutes, the switch should automatically collect detailed process information and send an alert. Which built-in AOS-CX feature is best suited for this type of intelligent, on-box monitoring and automation?

Accepted Answer

Network Analytics Engine (NAE)

Answer

The Network Analytics Engine (NAE) is a built-in framework in AOS-CX that allows for monitoring and troubleshooting through simple scripting. NAE agents can monitor system states (like CPU utilization), and when a condition is met, they can trigger actions like collecting more data or sending customized alerts, making it perfect for this scenario.
