HPE Network Switching Associate Exam Sample Questions (Q120-Q125):

NEW QUESTION # 120
A network operator is managing a network that has grown to include over 500 devices in a single VLAN. Users are reporting that network performance is slow, especially during peak hours. The operator notes a high level of broadcast traffic, such as ARP requests and service discovery protocols. Why is this design a problem for network performance? (Select all that apply.)

Answer: C,D


NEW QUESTION # 121
While investigating a fault, you discovered that a LAG interface from an aggregation switch was connected to two different access switches.
How can you re-configure the LAG interface so it will only come up if connected to the same access switch?

Answer: C

Explanation:
Configuring a static LAG ensures that the port-channel only comes up when all member links are connected to the same switch, preventing misconfigurations across different access switches.


NEW QUESTION # 122
Why would a device perform an ARP request?

Answer: A

Explanation:
The correct answer is B. To find the destination MAC address for a specific IP address. ARP, or Address Resolution Protocol, is used on IPv4 Ethernet networks to map a Layer 3 IPv4 address to a Layer 2 MAC address. HPE Aruba Networking AOS-CX documentation states that ARP maps network addresses assigned to devices to physical addresses, and specifically maps IPv4 network addresses to Layer 2 MAC addresses on Ethernet networks. When a host wants to send traffic to another IPv4 device on the same local network, or to its default gateway, it must know the destination MAC address to build the Ethernet frame. If the MAC address is not already in its ARP table, it sends an ARP request asking which device owns the target IP address. Option A is incorrect because ARP is not used to find a source IP address. Option C is incorrect because the device already knows its own source MAC address. Option D describes reverse mapping, which is not the purpose of a normal ARP request.


NEW QUESTION # 123
When multiple routes exist to the same destination, which would be installed in the routing table?

Answer: B


NEW QUESTION # 124
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: C

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 # 125
