NEW QUESTION # 68
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 spanning tree on the Aruba CX 6200 and CX 6300 switches No trap option is needed
- C. Configure spanning tree on the Aruba CX 8325 switches Set the trap-option
- D. Configure loop protection on all edge ports of the Aruba CX 6200 and CX 6300 switches No trap option is needed
Answer: A
Explanation:
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. References:

NEW QUESTION # 69
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2?
(Select two.)
- A. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
- B. AP1 will cache the client's information and send it to the Key Management service
- C. The Key Management service then generates R1 keys for AP2's neighbors.
- D. A client associates and authenticates with the AP2 after roaming from AP1
- E. The Key Management service receives from AirMatch a list of all AP2's neighbors
Answer: B,C
Explanation:
Explanation
The correct steps that are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2 are A and D.
A: AP1 will cache the client's information and send it to the Key Management service. This is true because when a client associates and authenticates with AP1, AP1 will generate a pairwise master key (PMK) for the client and store it in its cache. AP1 will also send the PMK and other client information, such as MAC address, VLAN, and SSID, to the Key Management service, which is a centralized service that runs on Aruba Mobility Controllers (MCs) or Mobility Master (MM) devices1. The Key Management service will use this information to facilitate fast roaming for the client.
D: The Key Management service then generates R1 keys for AP2's neighbors. This is true because when the Key Management service receives the client information from AP1, it will use the PMK to derive R0 and R1 keys for the client. R0 keys are used to generate R1 keys, which are used to generate pairwise transient keys (PTKs) for encryption. The Key Management service will distribute the R1 keys to AP2 and its neighboring APs, which are determined by AirMatch based on RF proximity2. This way, when the client roams to AP2 or any of its neighbors, it can skip the 802.1X authentication and use the R1 key to quickly generate a PTK with the new AP3.
B: The Key Management service receives from AirMatch a list of all AP2's neighbors. This is false because the Key Management service does not receive this information from AirMatch directly. AirMatch is a feature that runs on MCs or MM devices and optimizes the RF performance of Aruba devices by using machine learning algorithms. AirMatch periodically sends neighbor reports to all APs, which contain information about their nearby APs based on signal strength and interference. The APs then send these reports to the Key Management service, which uses them to determine which APs should receive R1 keys for a given client2.
C: The Key Management service receives a list of all AP1 s neighbors from AirMatch. This is false for the same reason as B. The Key Management service does not receive this information from AirMatch directly, but from the APs that send their neighbor reports.
E: A client associates and authenticates with the AP2 after roaming from AP1. This is false because a client does not need to authenticate with AP2 after roaming from AP1 if it has already authenticated with AP1 and received R1 keys from the Key Management service. The client only needs to associate with AP2 and perform a four-way handshake using the R1 key to generate a PTK for encryption3. This is called fast roaming or
802.11r roaming, and it reduces the latency and disruption caused by full authentication.

Your customer has asked you to assign a switch management role for a new user The customer requires the user role to only have Web Ul access to the System > Log page and only have access to the GET method for REST API for the /logs/event resource Which default AOS-CX user role meets these requirements?
- A. operators
- B. auditors
- C. administrators
- D. sysops
Answer: B
Explanation:
Explanation
The auditors role is the default AOS-CX user role that meets the requirements of having Web UI access to the System > Log page and having access to the GET method for REST API for the /logs/event resource. The auditors role has a level of 1 and allows read-only access to most commands except those related to security or passwords. It also allows access to the Web UI and REST API with limited permissions. The other options are incorrect because they either have higher levels of access or do not allow access to the Web UI or REST API.

Explanation:
Explanation
AOS 10 Gateways can have the following personas: Mobility, Branch, and VPN Concentrator1 However, the Mobility persona is only available when configuring a Gateway-only group, which is a group that contains only one gateway device2 The Mobility persona provides Overlay WLAN and (or) wired LAN functionalities for campus networks1 The Branch persona provides the Aruba Instant OS and SD-Branch (LAN + WAN) functionality for branch and microbranch networks1 The VPN Concentrator persona provides VPN termination and routing functionality for remote access networks3 The Edge persona is not a valid option, as it is not a supported device persona for AOS 10 Gateways.
NEW QUESTION # 74
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 Enhanced security
- B. Enable Secure Mode Enhanced
- C. Enable GRE security
- D. Enable Enhanced PAPI security
Answer: A
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:

NEW QUESTION # 75
A customer is concerned about me unprotected traffic between an AOS-CX switch and a gateway, running on AOStO. What is a feasible option to protect this traffic?
- A. Implement an MD5 HMAC function lo protect PAPI between the AOS-CX switches and the gateway
- B. Implement a GRE tunnel to protect PAPI between the AOS-CX switches and the gateway
- C. Implement an IPSec tunnel to protect PAPI between the AOS-CX switches and the gateway
- D. no action is needed, an RSA certificate already encrypts the traffic
Answer: C
Explanation:
According to the Aruba Documentation Portal1, PAPI (Port Aggregation Protocol) is a protocol that allows multiple physical ports to be aggregated into a single logical port for increased bandwidth and performance. PAPI can be used between AOS-CX switches and gateways, or between AOS-CX switches and other devices.
Option A: Implement an IPSec tunnel to protect PAPI between the AOS-CX switches and the gateway This is because option A shows how to implement an IPSec tunnel between two devices using the interface command and the ipsec command. An IPSec tunnel can provide encryption and authentication for PAPI traffic between two devices, such as an AOS-CX switch and a gateway2.
Therefore, option A is a feasible option to protect this traffic.
I hope this helps you. If you need more information, please let me know.

With the Aruba CX switch configuration, what is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation?
- A. Active Gateway
- B. SVI with vsx-sync
- C. VRRP
- D. Active-Active VRRP
Answer: A
Explanation:
Active Gateway is the first-hop protocol feature that is used for VSX L3 gateway as per Aruba recommendation. Active Gateway is a feature that allows both VSX peers to act as active gateways for different subnets, eliminating the need for VRRP or other first-hop redundancy protocols. Active Gateway also provides fast failover and load balancing for L3 traffic across the VSX peers. The other options are incorrect because they are either not recommended or not supported by Aruba CX VSX.

NEW QUESTION # 77
How is Multicast Transmission Optimization implemented in an HPE Aruba wireless network?
- A. The optimal rate for sending multicast frames is based on the lowest unicast rate across all associated clients.
- B. "The optimal rate for sending multicast frames is based on the highest 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 broadcast rate across all associated clients.
Answer: A
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 # 78
Which statements regarding 0SPFv2 route redistribution are true for Aruba OS CX switches? (Select two.)
- A. The "redistribute connected" command will redistribute all connected routes for the switch except local loopback addresses.
- B. The "redistribute connected" command will redistribute all connected routes for the switch including local loopback addresses
- C. The "redistribute static route-map connected-routes" command will redistribute all static routes with a matching permit in the route map "connected-routes-
- D. The "redistribute ospf" command will redistribute routes from all OSPF V2 and V3 processes
- E. The "redistribute static route-map connected-routes" command will redistribute all static routes without a matching deny in the route map "connected-routes".
Answer: B,C
Explanation:
These are two correct statements regarding OSPFv2 route redistribution for Aruba OS CX switches. Route redistribution is a process that allows routes from one routing protocol or source to be injected into another routing protocol or destination. OSPFv2 is a link-state routing protocol that supports route redistribution from various sources, such as connected, static, BGP, etc. The "redistribute connected" command will redistribute all connected routes for the switch, including local loopback addresses, into OSPFv2. The "redistribute static route-map connected-routes" command will redistribute all static routes that have a matching permit statement in the route map named "connected-routes" into OSPFv2. The other statements are incorrect because they either do not reflect the correct behavior of route redistribution commands or do not exist as valid commands.

NEW QUESTION # 79
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.
Answer: B
Explanation:
Explanation
OSPF (Open Shortest Path First) is a routing protocol that uses link-state information to calculate the best path to each destination in the network. OSPF establishes adjacencies with neighboring routers to exchange routing information and maintain a consistent view of the network topology1.
To establish an OSPF adjacency, the routers need to have some common parameters, such as the area ID, the network type, the hello interval, the dead interval, and the authentication method2. The routers also need to have a matching subnet mask on the interface that connects them3.
In this case, the Aruba CX 6300 VSF stack has an SVI (Switched Virtual Interface) on VLAN 10 with an IP address of 10.1.1.1/24 and a LAG (Link Aggregation Group) on port 1/1/1 and port 2/1/1 that connects to a neighboring device. The SVI is configured with OSPF area 0 and network type broadcast. The LAG is configured with OSPF passive mode, which means that it will not send or receive OSPF hello packets.
The neighboring device has an interface with an IP address of 10.1.1.2/24 and a LAG on port 1/0/1 and port
2/0/1 that connects to the Aruba CX 6300 VSF stack. The interface is configured with OSPF area 0 and network type broadcast.
Since the Aruba CX 6300 VSF stack and the neighboring device have the same area ID, network type, subnet mask, and default hello and dead intervals on their interfaces, they will be able to establish an OSPF adjacency over SVI 10 with LAG 1. The OSPF passive mode on the LAG will not affect the adjacency, because it only applies to the LAG interface, not the SVI interface.

NEW QUESTION # 81
With the Aruba CX switch configuration, what is the Active Gateway feature that is used for and is unique to VSX configuration?
- A. Sixteen different VMACS are supported for each IPV4 and IPV6 stack simultaneously
- B. Sixteen different VMACs are supported total as shared.
- C. Active Gateway can once MSTP instances are created for VLAN load sharing.
- D. copied over the ISL link for an optimized path.
Answer: A
Explanation:
The active gateway feature is used to provide active-active layer 3 default gateway for hosts on the same subnet. It allows the switch to convert multicast streams into unicast streams over the wireless link, which improves the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. The active gateway feature is unique to VSX configuration because it eliminates the need for VRRP and avoids traffic being pushed over the ISL link, which can cause latency in the network12.
The correct answer to the question is C. Sixteen different VMACs are supported for each IPv4 and IPv6 stack simultaneously. This means that you can have a maximum of eight VMACs for IPv4, and a maximum of eight VMACs for IPv6, on a VSX pair. Only 15 VMACs are supported on 6400 switch series2.
The other options are incorrect because:
A) Sixteen different VMACs are not supported total as shared. They are supported for each IPv4 and IPv6 stack separately.
B) Active gateway can be used without MSTP instances. MSTP is a protocol that allows multiple spanning tree instances to coexist on the same switch, but it does not affect how active gateway works.
D) Active gateway does not copy traffic over the ISL link for an optimized path. It avoids using the ISL link for routed traffic and uses the local switch interface MAC instead of the virtual MAC address (VMAC) for source address1.
NEW QUESTION # 82
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 Enhanced PAPI security
- B. Enable Secure Mode Enhanced
- C. Enable GRE security
- D. Enable Enhanced security
Answer: A
Explanation:
Explanation
PAPI is the protocol that is used to establish tunnels between the CX switch and the Aruba Gateway for Dynamic Segmentation1. By default, PAPI uses a simple checksum to verify the integrity of the messages, but it does not encrypt the payload2. This could expose the network to spoofing or replay attacks by malicious actors. To address this situation, the administrator must enable Enhanced PAPI security, which uses AES-256 encryption and HMAC-SHA1 authentication to protect the tunnel traffic2. Enhanced PAPI security can be enabled on the CX switch by using the command system papi enhanced-security enable3. This will ensure that the tunnels built between the CX switch and the Aruba Gateway are encrypted and authenticated.
NEW QUESTION # 83
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. MAC tables
- C. RPVST+
- D. UDLD
Answer: D
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 # 84
The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration
What is the most likely cause of this issue?
- A. There is a mismatch between the RADIUS secret on the switch and CPPM.
- B. The SSL certificate for CPPM has not been added as a trust point on the switch
- C. Change of Authorization has not been globally enabled on the switch
- D. There is a time difference between the switch and the ClearPass Policy Manager
Answer: D
Explanation:
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated.

NEW QUESTION # 85
What are two advantages of splitting a larger OSPF area into a number of smaller areas? (Select two )
- A. It reduces processing overhead.
- B. it simplifies the configuration.
- C. It extends the LSDB
- D. It reduces the total number of LSAs
- E. It increases stability
Answer: A,E
Explanation:
Explanation
Splitting a larger OSPF area into a number of smaller areas has several advantages for network scalability and performance. Some of these advantages are:
It increases stability by limiting the impact of topology changes within an area. When a link or router fails in an area, only routers within that area need to run the SPF algorithm and update their routing tables. Routers in other areas are not affected by the change and do not need to recalculate their routes.
It reduces processing overhead by reducing the size and frequency of link-state advertisements (LSAs).
LSAs are packets that contain information about the network topology and are flooded within an area.
By dividing a network into smaller areas, each area has fewer LSAs to generate, store, and process, which saves CPU and memory resources on routers.
It reduces bandwidth consumption by reducing the amount of routing information exchanged between areas. Routers that connect different areas, called area border routers (ABRs), summarize the routing information from one area into a single LSA and advertise it to another area. This reduces the number of LSAs that need to be transmitted across area boundaries and saves network bandwidth.

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. 2dB
- C. 8dB
- D. 4dB
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.
