NEW QUESTION # 20
A customer wants to provide wired security as close to the source as possible The wired security must meet the following requirements:
-allow ping from the IT management VLAN to the user VLAN
-deny ping sourcing from the user VLAN to the IT management VLAN
The customer is using Aruba CX 6300s
What is the correct way to implement these requirements?
- A. Apply an inbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- B. Apply an outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
- C. Apply an inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
- D. Apply an outbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
Answer: A
Explanation:
Explanation
An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5. References: 4

NEW QUESTION # 21
Review the exhibit.
You are troubleshooting an issue with a 10 102.39 0/24 subnet which is also VLAN 1000 used Tor wireless clients on a pair of Aruba CX 8360 switches The subnet SVI is configured on the 8360 pair, and the DHCP server is a Microsoft Windows Server 2022 Standard with an IP address of 10 200 1.100. The 10.102.250.0/24 subnet is used for switch management.
A large number of DHCP requests are failing You are observing sporadic DHCP behavior across clients attached to the CX 6100 switch.
Which action may help fix the issue?
- A.
- B.
- C.
- D.
Answer: C
Explanation:
Explanation
Option B is the correct action that may help fix the issue of sporadic DHCP behavior across clients attached to the CX 6100 switch. Option B enables DHCP relay on VLAN 1000 interface on Core-1 switch, which allows DHCP requests from clients in VLAN 1000 to be forwarded to the DHCP server in a different subnet (10.200.1.100). Without DHCP relay, clients in VLAN 1000 cannot obtain IP addresses from the DHCP server because they are in different broadcast domains. The other options are incorrect because they either do not enable DHCP relay or do not configure it correctly. References:

NEW QUESTION # 22
You are configuring Policy Based Routing (PBR) for a subnet that will be used to test a new default route for your network Traffic originating from 10.2.250.0/24 should use a new default route to 10.1.1.253. Other non-default routes for this subnet should not be affected by this change.
What are two parts of the solution for these requirements? (Select two.)
- A.
- B.
- C.
- D.
- E.
Answer: B,D
Explanation:
Explanation
These are the correct parts of the solution for the requirements of configuring Policy Based Routing (PBR) for a subnet that will be used to test a new default route for your network. Option A defines a PBR policy named test-default-route with a rule named new-default-route that matches traffic from source IP address
10.2.250.0/24 and sets the next hop IP address to 10.1.1.253. Option E applies the PBR policy to VLAN 10 interface, which is the subnet that needs to use the new default route. The other options are incorrect because they either do not match the correct traffic or do not set the correct next hop. References:

NEW QUESTION # 23
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 an outdoor access point.
- D. The AP is configured in Mesh mode
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 # 24
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).
- A. CoS has much finer granularity than DSCP
- B. They are similar and can be used interchangeably.
- C. CoS is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.
- D. CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
Answer: D
Explanation:
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 # 25
A network engineer recently identified that a wired device connected to a CX Switch is misbehaving on the network To address this issue, a new ClearPass policy has been put in place to prevent this device from connecting to the network again.
Which steps need to be implemented to allow ClearPass to perform a CoA and change the access for this wired device? (Select two.)
- A. Bounce the switchport
- B. Confirm that NTP is configured on the switch and ClearPass
- C. Configure dynamic authorization on the switch.
- D. Use Dynamic Segmentation.
- E. Configure dynamic authorization on the switchport
Answer: B,C
Explanation:
Explanation
To allow ClearPass to perform a CoA and change the access for a wired device, the following steps need to be implemented:
* Confirm that NTP is configured on the switch and ClearPass. NTP is required to synchronize the time between the switch and ClearPass, which is essential for CoA messages to be processed correctly1.
* Configure dynamic authorization on the switch. Dynamic authorization is a feature that enables the switch to accept CoA messages from a RADIUS server and apply them to existing sessions2. Dynamic authorization can be enabled globally or per port on the switch2.
* Optionally, configure dynamic authorization on the switchport. This step is not required, but it can provide more granular control over which ports can accept CoA messages from a RADIUS server2.
Bouncing the switchport or using Dynamic Segmentation are not necessary steps for allowing ClearPass to perform a CoA and change the access for a wired device. References: 1

NEW QUESTION # 26
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)
- A. A client associates and authenticates with the AP2 after roaming from AP1
- B. The Key Management service then generates R1 keys for AP2's neighbors.
- C. The Key Management service receives from AirMatch a list of all AP2's neighbors
- D. AP1 will cache the client's information and send it to the Key Management service
- E. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
Answer: B,E
Explanation:
Explanation
Key Management is a service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) to optimize roaming performance for wireless clients. Key Management works with AirMatch, a service that optimizes radio resource management for Aruba APs, to pre-generate and distribute R1 keys for neighboring APs before a client roams. When a wireless device is roaming from AP1 to AP2, the following steps are part of the Key Management workflow3:
* The client associates and authenticates with AP1 using 802.1X or PSK methods.
* The Key Management service caches the client's information and generates an R0 key for the client.
* The Key Management service receives a list of all AP1's neighbors from AirMatch.
* The Key Management service then generates R1 keys for AP1's neighbors using the R0 key and sends them to the corresponding APs.
* When the client roams to AP2, one of AP1's neighbors, it performs an 802.11r fast transition using the pre-generated R1 key without needing to re-authenticate.

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. Static VXLAN
- B. Generic Routing Encapsulation (GRE)
- C. EVPN-VXLAN
- D. Ethernet over IP (EolP)
Answer: C
Explanation:
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

NEW QUESTION # 29
You are helping an onsite network technician bring up an Aruba 9004 gateway with ZTP for a branch office The technician was to plug in any port for the ZTP process to start Thirty minutes after the gateway was plugged in new users started to complain they were no longer able to get to the internet. One user who reported the issue stated their IP address is 172.16 0.81 However, the branch office network is supposed to be on 10.231 81.0/24.
What should the technician do to alleviate the issue and get the ZTP process started correctly?
- A. Move the cable on the gateway to G0/0/1. and add the device's MAC and Serial number in Central
- B. Factory default and reboot the gateway to restart the process.
- C. Move the cable on the gateway from port G0/0V1 tc port GO 0.0
- D. Turn off the DHCP scope on the gateway, and set DNS correctly on the gateway to reach Aruba Activate
Answer: A
Explanation:
Explanation
This is the correct action to alleviate the issue and get the ZTP (Zero Touch Provisioning) process started correctly for an Aruba 9004 gateway. ZTP is a feature that allows an Aruba gateway to automatically download its configuration from Aruba Central without any manual intervention. To use ZTP, the gateway must be connected to a DHCP-enabled network and have Internet access. The gateway must also be added to Aruba Central using its MAC address and serial number. The default port for ZTP on an Aruba 9004 gateway is G0/0/1, which is labeled as Internet on the device. The other options are incorrect because they either do not use the correct port for ZTP or do not add the device to Aruba Central. References:

NEW QUESTION # 30
Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?
- A. Spectrum Monitor
- B. Air Monitor
- C. Dual Mode
- D. Hybrid Mode
Answer: A
Explanation:
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. References:

When setting up an Aruba CX VSX pair, which information does the Inter-Switch Link Protocol configuration use in the configuration created?
- A. QSVI
- B. UDLD
- C. RPVST+
- D. MAC tables
Answer: B
Explanation:
Explanation
UDLD (Unidirectional Link Detection) is the information that the Inter-Switch Link Protocol configuration uses in the configuration created for Aruba CX VSX pair inter-switch-link. UDLD is a protocol that detects unidirectional links between switches and prevents loops or black holes in the network. UDLD is enabled by default on all ports that are part of the inter-switch-link between VSX peers. The other options are incorrect because they are either not related to inter-switch-link or not supported by Aruba CX VSX. References:

NEW QUESTION # 37
A company deployed Dynamic Segmentation with their CX switches and Gateways After performing a security audit on their network, they discovered that the tunnels built between the CX switch and the Aruba Gateway are not encrypted. The company is concerned that bad actors could try to insert spoofed messages on the Gateway to disrupt communications or obtain information about the network.
Which action must the administrator perform to address this situation?
- A. Enable GRE security
- B. Enable Enhanced PAPI security
- C. Enable Secure Mode Enhanced
- D. Enable Enhanced security
Answer: D
Explanation:
Explanation
To address the situation of unencrypted tunnels between the CX switch and the Aruba Gateway, the administrator must enable Enhanced security on both devices. Enhanced security is a feature that provides encryption and authentication for GRE tunnels between CX switches and Aruba Gateways using IPSec.
Enhanced security can be enabled globally or per tunnel on both devices using CLI commands or Web UI options. The other options are incorrect because they either do not provide encryption or authentication for GRE tunnels or do not exist as features. References:
