HPE Network Switching Associate Exam Sample Questions (Q80-Q85):

NEW QUESTION # 80
A Solutions Architect is investigating a complex, intermittent issue in a multi-tier campus network.
Users are reporting that access to a critical internal application server (10.100.1.50) is periodically slow or times out. The network consists of multiple AOS-CX switches. The architect suspects a routing problem or a silent packet drop at one of the intermediate Layer 3 hops. The goal is to non-disruptively trace the path and identify the point of failure.
Which general troubleshooting tool should the architect use from the user's gateway switch to identify every Layer 3 hop on the path to the application server and measure the latency to each hop?

Answer: D


NEW QUESTION # 81
How many broadcast domains are shown in the diagram below?

Answer: C

Explanation:
The correct answer is B. 2. The diagram shows two VLANs: VLAN 10 and VLAN 20. In Ethernet switching, each VLAN represents a separate Layer 2 broadcast domain. HPE Aruba Networking documentation defines a VLAN as a single Layer 2 network that can be partitioned to create multiple distinct broadcast domains, isolated from each other unless traffic passes through a router or Layer 3 interface. In this diagram, PCs A and B are in VLAN 10, so they share one broadcast domain. PCs C and D are in VLAN 20, so they share a second broadcast domain. The Layer 3 switch has SVIs for VLAN 10 and VLAN 20, which allow routing between the two VLANs, but the SVIs do not merge the broadcast domains. They provide Layer 3 gateways for each VLAN. Therefore, the number of broadcast domains is based on the number of VLANs shown, not the number of PCs, switch links, or SVIs. Since there are two VLANs, there are two broadcast domains.


NEW QUESTION # 82
The configuration below is an example of which security concept?
Switch(config)# user-group external-auditors
Switch(config-ur-grp-external-auditors)# 10 permit cli command " show version " Switch(config-ur-grp-external-auditors)# 20 permit cli command " show run "

Answer: D

Explanation:
The correct answer is D. Role-based Access Control. The configuration creates a user-defined local user group named external-auditors and then permits only specific CLI commands for that group. HPE Aruba Networking AOS-CX hardening documentation explains that user-defined local groups are used for local authorization and that local authorization uses role-based access control, or RBAC, to provide role-based privilege levels and optional command execution rules. The CLI command documentation also states that permit or deny cli command rules define which CLI commands can be executed by members of a user- defined group, with an implicit deny rule at the end. This matches RBAC because access is granted according to the user's assigned role or group. Option A is incorrect because authentication verifies identity, such as username and password. Option B is incorrect because accounting records user activity. Option C is broader security architecture terminology, but the specific configuration shown is command authorization through RBAC.


NEW QUESTION # 83
Why would a device perform an ARP request?

Answer: C

Explanation:
A device uses ARP to resolve an IP address to its corresponding MAC address so it can correctly deliver Ethernet frames on the local network.


NEW QUESTION # 84
How many broadcast domains are shown in the diagram below?

Answer: C

Explanation:
Each VLAN is a separate Layer 2 broadcast domain. The diagram shows VLAN 10 and VLAN 20, so there are two broadcast domains.
