NEW QUESTION # 101
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working across the campus which is connected via layer-3. The legacy devices are connected to Aruba CX 6300 switches throughout the campus.
Which technology minimizes flooding so the legacy application can work efficiently?
- A. EVPN-VXLAN
- B. Static VXLAN
- C. Ethernet over IP (EolP)
- D. Generic Routing Encapsulation (GRE)
Answer: A
Explanation:
EVPN-VXLAN is a technology that allows layer-2 communication across layer-3 networks by using Ethernet VPN (EVPN) as a control plane and Virtual Extensible LAN (VXLAN) as a data plane3. EVPN-VXLAN can be used to support legacy applications that communicate at layer-2 across different campuses or data centers that are connected via layer-3. EVPN-VXLAN minimizes flooding by using BGP to distribute MAC addresses and IP addresses of hosts across different VXLAN segments3. EVPN-VXLAN also provides benefits such as loop prevention, load balancing, mobility, and scalability3. References: 3 https://www.

NEW QUESTION # 102
You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
- A. loopback 0 and OSPF area 0 in default VRF
- B. routed port in custom VRF
- C. SVI, VLAN trunk allowed all on ISL in default VRF
- D. SVI, VLAN trunk allowed all on ISL in custom VRF
Answer: B
Explanation:
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. References:

NEW QUESTION # 104
A system engineer needs to preconfigure several Aruba CX 6300 switches that will be sent to a remote office An untrained local field technician will do the rollout of the switches and the mounting of several AP-515s and AP-575S. Cables running to theAPs are not labeled.
The VLANs are already preconfigured to VLAN 100 (mgmt), VLAN 200 (clients), and VLAN 300 (guests) What is the correct configuration to ensure that APs will work properly?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
Explanation
Option C is the correct configuration to ensure that APs will work properly. It uses the ap command to configure a port profile for APs with VLAN 100 as the native VLAN and VLAN 200 and 300 as tagged VLANs. It also enables LLDP on the ports to discover the APs and assign them to the port profile automatically. The other options are incorrect because they either do not use the ap command, do not enable LLDP, or do not configure the VLANs correctly. References:

NEW QUESTION # 105
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).
- A. CoS is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.
- B. CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
- C. CoS has much finer granularity than DSCP
- D. They are similar and can be used interchangeably.
Answer: B
Explanation:
CoS and DSCP are both methods of marking packets for quality of service (QoS) purposes. QoS is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc. CoS stands for Class of Service and is a 3-bit field in the 802.1Q VLAN tag header. CoS can only be used on Ethernet frames that have a VLAN tag, and it can only be preserved within a single VLAN domain. DSCP stands for Differentiated Services Code Point and is a 6-bit field in the IP header. DSCP can be used on any IP packet, regardless of the underlying layer 2 technology, and it can be preserved throughout the IP packet flow, unless it is modified by intermediate devices.

NEW QUESTION # 106
Refer to the image.
Your customer is complaining of weak Wi-Fi coverage in their office. They mention that the office on the other side of the hall has much better signal What is the likely cause of this issue7
- A. The AP is using a directional antenna.
- B. The AP is a remote access point.
- C. The AP is configured in Mesh mode
- D. The AP is an outdoor access point.
Answer: A
Explanation:
Explanation
The likely cause of the issue of weak Wi-Fi coverage in the office is that the AP is using a directional antenna.
A directional antenna is an antenna that radiates or receives radio waves more strongly in one or more directions, creating a focused beam of signal. A directional antenna can provide better coverage and performance for a specific area, but it can also create dead zones or weak spots for other areas. The other options are incorrect because they either do not affect the Wi-Fi coverage or do not match the scenario.

NEW QUESTION # 107
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements. After the configuration was complete, it was noted that a user assigned with the administrators role did not have the appropriate level of access on the switch. The user was not limited to viewing nonsensitive configuration information and a level of 1 was not assigned to their role.
Which default management role should have been assigned for the user?
- A. config
- B. helpdesk
- C. operators
- D. sysadmin
Answer: C
Explanation:
The operators user role is a predefined role that allows users to view nonsensitive configuration information on the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The operators user role has a privilege level of 1, which is the lowest level of access on the switch.
The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires.

- A. DMO is configured globally for each SSID in use in the network.
- B. DMO is configured individually for each SSID in use in the network.
- C. DMO is configured globally for each VLAN in use in the network.
- D. The AP uses QoS to provide equal air time for multicast traffic.
Answer: B
Explanation:
Dynamic Multicast Optimization (DMO) in HPE Aruba Networking is configured per SSID, allowing multicast traffic to be converted dynamically to unicast for clients connected to that specific SSID. This enhances multicast performance and reliability over Wi-Fi, especially for applications like video streaming or IP surveillance.
NEW QUESTION # 109
How is Multicast Transmission Optimization implemented in an HPE Aruba wireless network?
- A. "The optimal rate for sending multicast frames is based on the highest broadcast rate across all associated clients
- B. The optimal rate for sending multicast frames is based on the lowest broadcast rate across all associated clients.
- C. When this option is enabled the minimum default rate for multicast traffic is set to 12 Mbps for 5 GHz
- D. The optimal rate for sending multicast frames is based on the lowest unicast rate across all associated clients.
Answer: D
Explanation:
multicast transmission optimization is a feature that allows the IAP to select the optimal rate for sending broadcast and multicast frames based on the lowest of unicast rates across all associated clients1. When this option is enabled, multicast traffic can be sent at up to 24 Mbps. The default rate for sending frames for 2.4 GHz is 1 Mbps and 5.0 GHz is 6 Mbps. This option is disabled by default1.

NEW QUESTION # 112
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 loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches Set up 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 spanning tree on the Aruba CX 6200 and CX 6300 switches No trap option is needed
- D. Configure spanning tree on the Aruba CX 8325 switches Set the trap-option
Answer: A
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.

NEW QUESTION # 113
How do you allow a new VLAN 200 for downstream access switch with VSX pair using VSX LAG?
- A. vlan trunk add 100 in LAG1 multi-chassis
- B. vlan trunk allowed 200 in MLAG 1
- C. vlan trunk add 100 in MLAG1
- D. vlan trunk allowed all in LAG 1 multi-chassis
Answer: B
Explanation:
To allow a new VLAN (e.g., VLAN 200) on a downstream access switch that is connected to a VSX pair using a multi-chassis LAG (MLAG), the correct command is vlan trunk allowed 200 in MLAG 1.
This command allows VLAN 200 on the MLAG 1 interface, which spans both switches in the VSX pair and connects to the downstream device. This ensures consistent VLAN trunking across both peers without needing to separately configure each physical port.
NEW QUESTION # 114
What is true regarding 802.11k?
- A. It extends radio measurements to define mechanisms for wireless network management of stations
- B. It considers several metrics before it determines if a client should be steered to the 5GHz band, including client RSSI
- C. It provides mechanisms for APs and clients to dynamically measure the available radio resources.
- D. It reduces roaming delay by pre-authenticating clients with multiple target APs before a client roams to an AP
Answer: C
Explanation:
802.11k is a standard that provides mechanisms for APs and clients to dynamically measure the available radio resources in a wireless network. 802.11k defines radio resource management (RRM) functions, such as neighbor reports, link measurement, beacon reports, etc., that allow APs and clients to exchange information about the RF environment and make better roaming decisions. The other options are incorrect because they describe other standards, such as
802.11r, 802.11v, or 802.11ax.
NEW QUESTION # 115
You are deploying a bonded 40 MHz wide channel. What is the difference in the noise floor perceived by a client using this bonded channel as compared to an unbonded 20MHz wide channel?
- A. 3dB
- B. 4dB
- C. 8dB
- D. 6dB
Answer: A
Explanation:
The difference in the noise floor perceived by a client using a bonded 40 MHz wide channel as compared to an unbonded 20 MHz wide channel is 3 dB. The noise floor is the level of background noise in a given frequency band. When two adjacent channels are bonded, the noise floor increases by 3 dB because the bandwidth is doubled and more noise is captured. The other options are incorrect because they do not reflect the correct relationship between bandwidth and noise floor.
NEW QUESTION # 116
Refer to Exhibit. With Access-1, what needs to be identically configured With MSTP to load- balance VLANS?
- A. spanning-tree Cist mapping
- B. Spanning-tree instance vlan mapppjng
- C. Spanning-tree root-guard setting
- D. Spanning-tree bpdu-guard setting
Answer: B
Explanation:
To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
NEW QUESTION # 117
When setting up an AOS-CX VSX pair, which information does the Inter-Switch Protocol synchronize in the configuration created?
- A. LACP
- B. SVI
- C. UDLD
- D. RPVST+
Answer: A
Explanation:
In an AOS-CX VSX pair, the Inter-Switch Protocol (ISP) synchronizes LACP (Link Aggregation Control Protocol) configuration between the two VSX peers. This is essential because VSX LAGs (Multi-Chassis LAGs) must present a consistent LACP identity to downstream devices, making them appear as a single logical switch. ISP ensures both peers share the same LACP system MAC and priority so that connected devices see one unified LAG.
NEW QUESTION # 118
You need to create a keepalive network between two Aruba CX 8325 switches for VSX configuration How should you establish the keepalive connection?
- A. loopback 0 and OSPF area 0 in default VRF
- B. routed port in custom VRF
- C. SVI, VLAN trunk allowed all on ISL in default VRF
- D. SVI, VLAN trunk allowed all on ISL in custom VRF
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.

NEW QUESTION # 119
Refer to Exhibit:
With Access-1, What needs to be identically configured With MSTP to load-balance VLANS?
- A. spanning-tree Cist mapping
- B. Spanning-tree instance vlan mapppjng
- C. Spanning-tree root-guard setting
- D. Spanning-tree bpdu-guard setting
Answer: B
Explanation:
The correct answer is B. Spanning-tree instance VLAN mapping.
To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
According to the Cisco documentUnderstand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is:
* Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration:
Switch D1(config)#spanning-tree mst configuration
Switch D1(config-mst)#instance 1 vlan 501-1000
Switch D1(config-mst)#exit
Switch D1(config)#spanning-tree mst 1 priority 0
Switch D2(config)#spanning-tree mst configuration
Switch D2(config-mst)#instance 2 vlan 1-500
Switch D2(config-mst)#exit
Switch D2(config)#spanning-tree mst 2 priority 0
The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.
The other options are incorrect because:
* A. Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.
* C. Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.
* D. Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.
NEW QUESTION # 120
A company recently deployed new Aruba Access Points at different branch offices Wireless
802.1X authentication will be against a RADIUS server in the cloud. The security team is concerned that the traffic between the AP and the RADIUS server will be exposed..
What is the appropriate solution for this scenario?
- A. Enable EAP-TTLS on all wireless devices.
- B. Configure RadSec on the AP and Aruba Central.
- C. Enable EAP-TLS on all wireless devices
- D. Configure RadSec on the AP and the RADIUS server
Answer: D
Explanation:
This is the appropriate solution for this scenario where wireless 802.1X authentication will be against a RADIUS server in the cloud and the security team is concerned that the traffic between the AP and the RADIUS server will be exposed. RadSec, also known as RADIUS over TLS, is a protocol that provides encryption and authentication for RADIUS traffic over TCP and TLS.
RadSec can be configured on both the AP and the RADIUS server to establish a secure tunnel for exchanging RADIUS packets. The other options are incorrect because they either do not provide encryption or authentication for RADIUS traffic or do not involve RadSec.
NEW QUESTION # 121
A customer wants to enable wired authentication across all their CX switches One of the requirements is that the switch must be able to authenticate a single computer connected through a VoIP phone.
Which feature should be enabled to support this requirement?
- A. MAC Authentication
- B. Multi-Domain Authentication
- C. Multi-Auth Mode
- D. Device-Based Mode
Answer: B
Explanation:
Explanation
Multi-Domain Authentication is the feature that should be enabled to support the requirement that the switch must be able to authenticate a single computer connected through a VoIP phone. Multi-Domain Authentication is a feature that allows an Aruba CX switch to apply different authentication methods and policies to different devices connected to the same port. For example, a VoIP phone and a computer can be connected to the same port using a single cable, but they can be authenticated separately using different credentials and assigned to different VLANs. The other options are incorrect because they either do not support multiple devices on the same port or do not provide authentication. References:

Which statements are true about VSX LAG? (Select two.)
- A. The total number of configured links may not exceed 8 for the pair or 4 per switch
- B. Outgoing traffic is preferentially switched to local members of the LAG.
- C. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.
- D. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
- E. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
Answer: B,E
Explanation:
VSX LAG is a feature that allows a pair of Aruba CX switches to form a multichassis LAG with a downstream or upstream device. VSX LAG provides link redundancy and load balancing across the two switches. Outgoing traffic from the VSX pair to the peer device is switched to a port based on a hashing algorithm that considers various parameters such as source and destination MAC addresses, IP addresses, ports, etc. The hashing algorithm may select a port that belongs to either switch in the pair, depending on the traffic characteristics. However, outgoing traffic is preferentially switched to local members of the LAG, meaning that each switch tries to use its own ports first before using the ISL link to send traffic to the other switch's ports. This reduces the ISL utilization and improves performance.

A network administrator is attempting to troubleshoot a connectivity issue between a group of users and a particular server. The administrator needs to examine the packets over a period of time from their desktop; however, the administrator is not directly connected to the AOS-CX switch involved with the traffic flow.
What statements are correct regarding the ERSPAN session that needs to be established on an AOS-CX switch? (Select two)
- A. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
- B. The encapsulation protocol used is GRE.
- C. The encapsulation protocol used is VXLAN.
- D. The encapsulation protocol is UDP.
- E. On the source AOS-CX switch, the destination specified is the administrators desktop
Answer: B,E
Explanation:
These are the correct statements regarding the ERSPAN session that needs to be established on an AOS-CX switch for a network administrator to examine the packets over a period of time from their desktop. ERSPAN (Encapsulated Remote Switched Port Analyzer) is a feature that allows an AOS-CX switch to mirror traffic from one or more source ports or VLANs to a remote destination IP address over a GRE (Generic Routing Encapsulation) tunnel. The destination IP address must be the IP address of the administrator's desktop, which must have a packet capture tool installed to receive and analyze the mirrored traffic. The encapsulation protocol used for ERSPAN is GRE, which adds a header to the mirrored packets with information such as source and destination IP addresses, session ID, etc. The other statements are incorrect because they either do not specify the correct destination IP address or do not use ERSPAN or GRE.
