HPE Network Switching Associate Exam Sample Questions (Q23-Q28):

NEW QUESTION # 23
Which two benefits does QoS provide? (Choose two.)

Answer: A,C

Explanation:
Quality of Service (QoS) is a set of techniques used to manage and optimize network traffic, ensuring that certain types of traffic receive priority over others. The two main benefits of QoS are:
C). Reduces network congestion: QoS can prioritize certain traffic types, helping to prevent congestion by ensuring critical traffic (such as VoIP or video conferencing) gets through the network even during periods of high demand. By managing bandwidth allocation, it can help reduce the impact of congestion.
D). Prioritizes critical applications: QoS allows administrators to prioritize traffic from critical applications, ensuring that important services (like real-time voice or video) receive the necessary bandwidth and low latency, even in times of high network usage.


NEW QUESTION # 24
While deploying new HPE Aruba Networking CX switches on the customer site, which statement is true for neighbor switch discovery on the OS-CX?

Answer: B

Explanation:
On HPE Aruba OS-CX switches, LLDP is not enabled globally by default and must be explicitly enabled to allow neighbor switch discovery across the network.


NEW QUESTION # 25
Which firewall port needs to be opened between your Network Monitoring System and HPE Aruba Networking CX switches to collect monitoring data using SNMP?

Answer: B

Explanation:
The correct answer is D. UDP 161. SNMP uses different UDP ports depending on the monitoring function.
When a Network Monitoring System collects or polls monitoring data from a CX switch, it communicates with the SNMP agent on the switch. HPE Aruba Networking AOS-CX SNMP documentation shows the SNMP agent port as UDP 161. This is the port used for SNMP polling and monitoring responses. This differs from SNMP traps or alerts, which are sent by the switch to a monitoring system on UDP 162. The question specifically asks about the Network Monitoring System collecting monitoring data from CX switches, so the required firewall allowance is UDP 161 from the monitoring system to the switch. Option A is incorrect because TCP 162 is not the standard SNMP polling port. Option B and option C are incorrect because UDP
1157 and TCP 1156 are not the SNMP polling ports used for this purpose.


NEW QUESTION # 26
Which firewall port needs to be open between your CX switches and RADIUS server for authentication?

Answer: B

Explanation:
RADIUS authentication uses UDP port 1812, which must be open between the CX switches and the RADIUS server to allow authentication requests and responses.


NEW QUESTION # 27
A switch port is up, but no traffic is being forwarded. What could be a possible reason?

Answer: B

Explanation:
The Spanning Tree Protocol (STP) is used to prevent loops in a network by designating one active path and blocking redundant paths. If a switch port is up but no traffic is being forwarded, it's likely that the port is in a blocking state due to STP. This means that STP has determined that the port is part of a redundant path and has blocked it to avoid network loops.
