Your Aruba CX 6300 VSF stack has OSPF adjacency over SVI 10 with LAG 1 to a neighboring device.
The following configuration was created on the switch:
A)
B)
C)
D)
- A . Option A
- B . Option B
- C . Option C
- D . Option D
Suggested Answer: C
Explanation:
The correct configuration for OSPF adjacency over SVI 10 with LAG 1 to a neighboring device is shown in Option C.
The configuration includes the following steps:
* Create a VLAN 10 and assign it a name and an IP address.
* Create a LAG 1 and assign it a name and a mode of dynamic or static.
* Add member ports to LAG 1 and enable the LAG interface.
* Assign VLAN 10 as the untagged VLAN for LAG 1.
* Enable OSPF on the switch and assign it a router ID.
* Create an OSPF area 0 and add SVI 10 as an interface in that area.
Option A is incorrect because it does not enable OSPF on the switch or create an OSPF area. Option B is incorrect because it assigns VLAN 10 as the tagged VLAN for LAG 1, which is not compatible with SVI 10.
Option D is incorrect because it does not add member ports to LAG 1 or enable the LAG interface.

The customer needs a network hardware refresh to replace an aging Aruba 5406R core switch pair using spanning tree configuration with Aruba CX 8360-32YC switches.
What is the benefit of VSX clustering with the new solution?
- A . stacked data-plane
- B . faster MSTP converge processing
- C . dual Aruba AP LAN port connectivity for PoE redundancy
- D . dual control plane provides better resiliency
Suggested Answer: D
Explanation:
VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management.
VSX clustering has several benefits over spanning tree configuration, such as:
* Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.
* Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.
* Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.

What is enabled by LLDP-MED? (Select two.)
- A . Voice VLANs can be automatically configured for VoIP phones
- B . APs can request power as needed from PoE-enabled switch ports
- C . iSCSl client devices can request to have flow control enabled
- D . GVRP VLAN information can be used to dynamically add VLANs to a trunk
- E . iSCSl client devices can set the required MTU setting for the port.
Suggested Answer: A B
Explanation:
These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery).
LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP
phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies.
Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to
adjust their power consumption and performance based on the available power budget. The other
options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED.

What is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports?
- A . Implement a control plane ACL to limit access to approved IPs and/or subnets
- B . Manually enable Enhanced Security Mode from a console session.
- C . Disable all management services on the default VRF.
- D . Create a dedicated management VRF, and assign the management port to it.
Suggested Answer: D
Explanation:
This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

A customer is using stacked Aruba CX 6200 and CX 6300 switches for access and a VSX pair of Aruba CX 8325 as a collapsed core 802 1X is implemented for authentication. Due to the lack of cabling, some unmanaged switches are still in use Sometimes devices behind these switches cause network outages The switch should send a warning to the helpdesk when the problem occurs You have been asked to implement an effective solution to the problem.
What is the solution for this?
- A . Configure spanning tree on the Aruba CX 8325 switches Set the trap-option
- B . Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches No trap option is needed
- C . Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches Set up the trap-option
- D . Configure spanning tree on the Aruba CX 6200 and CX 6300 switches No trap option is needed
Suggested Answer: C
Explanation:
This is the correct solution to the problem of devices behind unmanaged switches causing network outages due to loops. Loop protection is a feature that allows an Aruba CX switch to detect and prevent loops by sending loop protection packets on each port, LAG, or VLAN on which loop protection is enabled. If a loop protection packet is received by the same switch that sent it, it indicates a loop exists and an action is taken based on the configuration. Loop protection should be configured on all edge ports of the Aruba CX 6200 and CX 6300 switches, which are the ports that connect to end devices or unmanaged switches. The trap-option should be set up to send a warning to the helpdesk when a loop is detected. The other options are incorrect because they either do not configure loop protection or do not set up the trap-option.

Which feature supported by SNMPv3 provides an advantage over SNMPv2c?
- A . Transport mapping
- B . Community strings
- C . GetBulk
- D . Encryption
Suggested Answer: D
Explanation:
Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key.
SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3.

Two AOS-CX switches are configured with VSX at the the Access-Aggregation layer where servers attach to them An SVI interface is configured for VLAN 10 and serves as the default gateway for VLAN 10. The ISL link between the switches fails, but the keepalive interface functions. Active gateway has been configured on the VSX switches.
What is correct about access from the servers to the Core? (Select two.)
- A . Server 1 can access the core layer via the keepalrve link
- B . Server 2 can access the core layer via the keepalive link
- C . Server 2 cannot access the core layer.
- D . Server 1 can access the core layer via both uplinks
- E . Server 1 and Server 2 can communicate with each other via the core layer
- F . Server 1 can access the core layer on only one uplink
Suggested Answer: D E
Explanation:
These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios that are not possible or not relevant to the question.

What is an OSPF transit network?
A. a network that uses tunnels to connect two areas
B. a special network that connects two different areas
C. a network on which a router discovers at least one neighbor
D. a network that connects to a different routing protocol
Suggested Answer: C
Explanation:
A. a network that uses tunnels to connect two areas - This is not the standard definition of a transit network in OSPF. While tunnels can be used in OSPF for various purposes (e.g., OSPF virtual links), they are not specifically what defines a transit network.
B. a special network that connects two different areas - While an OSPF network might connect two areas, particularly if it's an Area Border Router (ABR), this doesn't define what a transit network is. Any OSPF-enabled network segment where routers form adjacencies and forward data can be a transit network, irrespective of areas.
D. a network that connects to a different routing protocol - This is describing a boundary where OSPF interfaces with another routing protocol, typically managed using redistribution. This isn't what defines a transit network in OSPF.

Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?
- A . Hybrid Mode
- B . Air Monitor
- C . Spectrum Monitor
- D . Dual Mode
Suggested Answer: C
Explanation:
Spectrum Monitor is an Aruba AP mode that is sending captured RF data to Aruba Central for waterfall plot.
Spectrum Monitor is a mode that allows an AP to scan all channels in both 2.4 GHz and 5 GHz bands and collect information about the RF environment, such as interference sources, noise floor, channel utilization, etc. The AP then sends this data to Aruba Central, which is a cloud-based network management platform that can display the data in various formats, including waterfall plot. Waterfall plot is a graphical representation of the RF spectrum over time, showing the frequency, amplitude, and duration of RF signals. The other options are incorrect because they are either not AP modes or not sending RF data to Aruba Central.

You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
- A . SVI, VLAN trunk allowed all on ISL in default VRF
- B . routed port in custom VRF
- C . loopback 0 and OSPF area 0 in default VRF
- D . SVI, VLAN trunk allowed all on ISL in custom VRF
Suggested Answer: B
Explanation:
To establish a keepalive connection between two Aruba CX 8325 switches for VSX configuration, you need to use a routed port in custom VRF. A routed port is a physical port that acts as a layer 3 interface and does not belong to any VLAN. A custom VRF is a virtual routing and forwarding instance that provides logical separation of routing tables. By using a routed port in custom VRF, you can isolate the keepalive traffic from other traffic and prevent routing loops or conflicts. The other options are incorrect because they either do not use a routed port or do not use a custom VRF.
