HPE Network Switching Associate Exam Sample Questions (Q79-Q84):

NEW QUESTION # 79
On a switched infrastructure using spanning tree, what entity defines the best path for traffic in an HPE Aruba Networking CX environment?

Answer: C

Explanation:
In a spanning tree environment, the root bridge serves as the reference point, and all switches calculate the best path to the root bridge, which determines the optimal path for traffic forwarding.


NEW QUESTION # 80
You have configured the following on a Core-1 HPE Aruba Networking CX switch for primary and secondary ISP connectivity:
Core-1(config)# ip route 0.0.0.0/0 10.1.251.2
Core-1(config)# ip route 0.0.0.0/0 10.1.252.2 distance 10
The default route via 10.1.251.2 stopped working, and no failover happened. The ISP reported a broken fiber on the path of an upstream device.
In what condition should the route fail over to the 10.1.252.2 router?

Answer: B


NEW QUESTION # 81
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 # 82
A Network Operator is setting up a new server that will host a secure website (HTTPS) and also respond to basic network connectivity tests. Which two well-known TCP or UDP ports would the server need to have open on its firewall to allow these two services? (Choose 2.)

Answer: B,C


NEW QUESTION # 83
Drag and Drop Question
Match each example to the corresponding security concept.

Answer:

Explanation:

Explanation:
Alice has entered the correct password: Authentication
An auditor is granted read-only access to create a compliance report: Authorization Bob is permitted to run the CLI command "show running-config" only: Role-based Access Control Trudy modified the switch config via CLI on Tuesday the 2nd of July 2024: Accounting Authentication verifies a user's identity by validating credentials. Authorization defines what level of access a verified user is granted. Role-based access control enforces permissions based on assigned roles and allowed commands. Accounting records and tracks user actions for auditing and accountability purposes.
