How would you explain the functionality of an HPE Aruba Networking VSX inter-switch link protocol (ISLP)?
- A. ISLP requires a Routed Only Port to be enabled for VSX.
- B. ISLP utilized the keepalive L3 connectivity to synchronize switch configuration.
- C. ISLP periodically synchronizes protocol states, such as RPVST+.
- D. ISLP periodically synchronizes protocol states, such as LACP.
Answer: D
Explanation:
The VSX Inter-Switch Link Protocol (ISLP) periodically synchronizes protocol states, such as LACP, between VSX switches to maintain consistent link aggregation and ensure traffic continues to flow correctly.
NEW QUESTION # 34

- A. show ospf routes
- B. show ip ospf summary
- C. show ip route ospf
- D. display ospf routing

NEW QUESTION # 35
Which CLI command removes IGMP snooping from an Aruba CX switch?
- A. clear multicast igmp
- B. unset igmp snooping
- C. disable igmp snooping
- D. no ip igmp snooping
Answer: D
Explanation:
The no ip igmp snooping command disables multicast filtering, allowing multicast packets to be flooded to all ports within the VLAN instead of optimized forwarding.
NEW QUESTION # 36
Examine the commands entered on an AOS-CX switch:
What is true regarding this configuration for traffic received on interface 100?
- A. The next-hop address of 1.1.1.1 is overwritten by the next-hop address of 2.2.2.2
- B. The default next-hop address supersedes the two preceding next-hop addresses
- C. The traffic will be routed with the IP routing table entries if the next-hop addresses are unreachable
- D. The traffic is always dropped is the next-hop addresses are unreachable
Answer: C
Explanation:
If 1.1.1.1 is not reachable then next hop uses 2.2.2.2 if both of these are unreachable then normal routing table is used..and only if no route is available in routing table then default next-hop will kick-in.
NEW QUESTION # 37
Which two Aruba CX switch features enhance resiliency and network redundancy? (Select two)
- A. Virtual Switching Extension (VSX)
- B. Zero Touch Provisioning (ZTP)
- C. Aruba NetEdit
- D. Multi-Chassis Link Aggregation (MC-LAG)
Answer: A,D
Explanation:
MC-LAG ensures link redundancy, preventing single points of failure, while VSX enables active-active failover between core switches, improving network availability.
NEW QUESTION # 38
Based on the given output from an HPE Aruba Networking CX 6300:
Which statement about the output above is true?
- A. The defined route map is used in BGP with neighbor remote-as export.
- B. The advertised AS paths are configured in an IP prefix-list.
- C. The advertised AS path is longer than by default.
- D. The advertised routes have a MED value of 100.
Answer: C
Explanation:
The exhibit shows a configuration for a Route Map named BGP-EXPORT. To identify the correct statement, we must analyze the specific BGP attributes being manipulated in the sequence entries.
* Analyzing Sequence 10:
* Match: It looks for network prefixes defined in an IP prefix-list named bgp-export.
* Set: It executes the command as-path prepend 65345 65345 65345.
* AS Path Prepending: In BGP, the " Shortest AS Path " is one of the primary decision factors in the Best Path Selection Algorithm. AS Path Prepending is a technique used by network administrators to make a specific route appear " less desirable " to external neighbors. By adding multiple instances of an AS number (in this case, AS 65345 is added three times) to the existing AS Path, the switch artificially increases the length of the path.
* Conclusion for Statement B: Because the route map prepends the AS path for the matched prefixes, the resulting BGP update sent to neighbors will contain an AS path that is significantly longer than the default (which would normally just include the local AS). Therefore, statement B is true.
* Evaluating other options:
* Option A: This is technically incorrect syntax. Route maps are applied to BGP neighbors using the command neighbor [IP] route-map BGP-EXPORT out (for export) or in (for import). There is no " remote-as export " command for binding route maps.
* Option C: There is no set metric or set med command visible in the output. MED (Multi-Exit Discriminator) is a different attribute used to influence inbound traffic from an adjacent AS.
* Option D: This is a conceptual error. IP prefix-lists are used to match IP addresses and subnet masks (the " prefixes " ). AS Path Lists (as seen in Seq 100) or regular expressions are used to match AS paths. You do not configure the path itself inside a prefix-list.
NEW QUESTION # 39
Refer to the partial exhibit from an HPE Aruba Networking CX 8325:
A new port on 1/1/25 must be reconfigured for an ISP router with the IP address of 10.10.10.2/30.
What is the correct configuration to achieve the layer-3 configuration without the risks of layer-2 loops?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
To connect an ISP router, the switch port must operate as a routed Layer-3 interface, not as an access or trunk port. This is done by enabling routing directly on the interface and assigning the IP address on that physical port, avoiding participation in any VLAN that could create Layer-2 loops. The configuration that sets routing, applies ip address 10.10.10.2/30, and brings the port up with no shutdown on interface 1/1/25 satisfies these requirements.

- B. Root guard
- C. BPDU guard
- D. Admin edge
Answer: B
NEW QUESTION # 46
Your customer's CX switches are managed in HPE Aruba Networking Central. You plan to deploy new APs connecting to your existing CX switches. Which report can you run to determine if there are enough available ports and PoE capacity?
- A. Infra Inventory
- B. Switch Capacity Planning
- C. Network
- D. Resource Utilization
Answer: B
Explanation:
When managing a network through HPE Aruba Networking Central , administrators have access to specialized reporting tools designed for lifecycle management and expansion planning.
* Purpose of the Switch Capacity Planning Report: This specific report is engineered to give a clear overview of physical and electrical headroom within the switching infrastructure. When preparing to add new Access Points (APs), two variables are critical:
* Port Density: The report identifies the number of available (unused) ports across various speeds (1GbE, 2.5GbE, 5GbE, etc.).
* PoE Budgeting: High-performance APs (such as Wi-Fi 6E or Wi-Fi 7 models) require significant Power over Ethernet (PoE) wattage (PoE+ or UPoE). The report calculates the Total PoE Budget vs. the Currently Allocated PoE , allowing you to see if the switch power supplies can handle the additional load.
* Evaluating Other Options:
* Option A (Infra Inventory): This report focuses on asset management. it provides details like serial numbers, MAC addresses, hardware models, and firmware versions. It does not provide real-time or historical port usage or PoE consumption data.
* Option C (Network): This is a broader summary report that typically focuses on connectivity, client counts, and overall network health rather than specific hardware resource limits.
* Option D (Resource Utilization): While this report is useful, it generally focuses on System Resources such as CPU usage, Memory (RAM) consumption, and temperature sensors rather than physical port availability or PoE power budgets.
* Best Practice: In an Aruba Central environment, running the Switch Capacity Planning report before a hardware refresh or expansion is a mandatory step to avoid " PoE starvation " or physical port shortages during the installation phase.
