HPE Network Switching Associate Exam Sample Questions (Q34-Q39):

NEW QUESTION # 34
A technician installed a new 550 series access point, which is cabled back to a CX 6000 series switch. However, there are no lights on the AP. What could cause this?

Answer: D

Explanation:
The 550 series access point requires Power over Ethernet from the switch to power on. If PoE is disabled on the CX 6000 switch interface, the access point will not receive power, resulting in no indicator lights.


NEW QUESTION # 35
A customer requires a network upgrade to replace their existing core switches. The new solution must support
100G speeds to the aggregation layer, with the ability to scale to a 12U chassis.
Which HPE Aruba Networking CX switch model would you initially propose?

Answer: A

Explanation:
The correct answer is A. CX 6400. The requirement calls for a chassis-based core switch that can scale to a
12U chassis and support 100G speeds toward the aggregation layer. HPE Aruba Networking CX 6400 QuickSpecs identify the CX 6400 as a modular switch family and include the larger CX 6410 chassis option, which is a 10-slot chassis platform. HPE also lists CX 6400 40/100GbE QSFP28 line modules, which provide the required 100G connectivity. This makes CX 6400 the correct fit for a chassis solution that can scale to the requested physical size and provide 100G uplinks. The CX 10000, CX 9300, and CX 8325 are fixed-form- factor platforms, not modular chassis solutions, so they do not match the stated chassis requirement.
Therefore, the best initial proposal is the HPE Aruba Networking CX 6400.


NEW QUESTION # 36
Which of the following best describes the purpose of rate limiting in networking?

Answer: D


NEW QUESTION # 37
New IoT devices cannot obtain an IP address from a DHCP server at 10.200.1.51. Based on the output below, what should you configure to resolve the issue?
interface vlan100
description IoT
ip address 10.100.1.1/24
exit
interface 1/1/16
no shutdown
description Thermostat
vlan access 100
spanning-tree port-type admin-edge
exit

Answer: C

Explanation:
The correct answer is B. Configure an IP helper for the DHCP server. The IoT device is connected to VLAN
100, whose Layer 3 SVI is 10.100.1.1/24. The DHCP server is 10.200.1.51, which is in a different subnet.
DHCP clients initially use broadcast messages to discover a DHCP server, and those broadcasts do not cross Layer 3 boundaries by default. HPE Aruba Networking AOS-CX documentation explains that DHCP relay forwards DHCP client requests to configured DHCP servers, and that the ip helper-address command defines the address of a remote DHCP server or relay agent. The documentation also states that IP helper addresses can be configured on Layer 3 interfaces, Layer 3 VLAN interfaces, and LAG interfaces. Therefore, the correct fix is to configure ip helper-address 10.200.1.51 under interface vlan100. Disabling STP is not appropriate and could create Layer 2 loop risk. A static route may be needed for reachability in some designs, but it does not relay DHCP broadcasts. Broadcast-to-unicast conversion is not the required AOS-CX DHCP relay configuration.


NEW QUESTION # 38
A Solutions Architect has just completed the Layer 3 configuration for a new campus core switch.
The configuration includes several Switched Virtual Interfaces (SVIs) for inter-VLAN routing and a static default route for internet access. Before handing the solution over to the operations team, the architect needs to perform a final validation of the IP routing setup. The architect needs to verify the following in a single, consolidated view:
* That the directly connected VLAN interfaces (SVIs) are active in the routing table.
* That the static default route is correctly installed and active.
* The IP addresses of any next-hop gateways.
Which of the following validation commands provides this complete overview of the switch's Layer
3 forwarding information?

Answer: D
