NEW QUESTION # 37
Which statements regarding 0SPFv2 route redistribution are true for Aruba OS CX switches? (Select two.)
- A. The "redistribute static route-map connected-routes" command will redistribute all static routes with a matching permit in the route map "connected-routes-
- B. The "redistribute connected" command will redistribute all connected routes for the switch except local loopback addresses.
- C. The "redistribute static route-map connected-routes" command will redistribute all static routes without a matching deny in the route map "connected-routes".
- D. The "redistribute connected" command will redistribute all connected routes for the switch including local loopback addresses
- E. The "redistribute ospf" command will redistribute routes from all OSPF V2 and V3 processes
Answer: A,D
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 # 38
You need to ensure that voice traffic sent through an ArubaOS-CX switch arrives with minimal latency. What is the best scheduling technology to use for this task?
- A. Rate limiting
- B. QoS shaping
- C. DWRR queuing
- D. Strict queuing
Answer: D
Explanation:
Strict queuing is the best scheduling technology to use for voice traffic on an AOS-CX switch.
Scheduling is a mechanism that determines how packets are transmitted from different queues on an egress port. Strict queuing is a scheduling method that gives the highest priority queue absolute preference over all other queues, regardless of their size or utilization. Voice traffic should be assigned to the highest priority queue and scheduled with strict queuing to ensure minimal latency and jitter. The other options are incorrect because they are either not scheduling methods or not optimal for voice traffic.
NEW QUESTION # 39
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.
Answer: A
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.

What are the requirements to ensure that WMM is working effectively'? (Select two)
- A. The Aruba AOS10 APs installed have to be converted to controlled mode
- B. The AP needs to be connected via a tagged VLAN to the wired port
- C. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
- D. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
- E. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.
Answer: D,E
Explanation:
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work. References:

NEW QUESTION # 43
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 and Server 2 can communicate with each other via the core layer
- B. Server 1 can access the core layer via both uplinks
- C. Server 1 can access the core layer on only one uplink
- D. Server 1 can access the core layer via the keepalrve link
- E. Server 2 can access the core layer via the keepalive link
- F. Server 2 cannot access the core layer.
Answer: A,B
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.

Your customer is having issues with Wi-Fi 6 clients staying connected to poor-performing APs when a higher throughput APs are closer. Which technology should you implement?
- A. Clearpass
- B. ARM
- C. Airmatch
- D. ClientMatch
Answer: D
Explanation:
Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also known as "high-efficiency wireless". Wi-Fi 6 offers increased capacities, improved resource utilization and higher throughput speeds than previous standards.
This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi- Fi 6 clients on a UniFi network. ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions.

NEW QUESTION # 47
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 total as shared.
- B. Active Gateway can once MSTP instances are created for VLAN load sharing.
- C. Sixteen different VMACS are supported for each IPV4 and IPV6 stack simultaneously
- D. copied over the ISL link for an optimized path.
Answer: C
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 # 48
Refer to the exhibit.
A company has deployed 200 AP-635 access points. To but is not working as expected What would be the correct action to fix the issue?
- A. Change the SSID to WPA3-Enterprise (CCM).
- B. Change the SSID to WPA3-Personal
- C. Change the SSID to WPA3-Enterpnse (CNSA).
- D. Change the SSID to WPA3-Enhanced Open
Answer: C
Explanation:
According to the Aruba Campus Access Professional documents1, WPA3-Enterprise is a security mode that supports 802.1X authentication and encryption with either AES-CCM or AES-GCMP. WPA3-Enterprise also optionally adds usage of Suite-B 192-bit minimum-level security suite that is aligned with Commercial National Security Algorithm (CNSA) for enterprise networks2. This mode provides the highest level of security and is suitable for government and financial institutions.
The exhibit shows that the SSID is configured with WPA3-Enterprise (CCM), which uses AES-CCM as the encryption protocol. However, this mode is not compatible with some devices that require CNSA compliance. Therefore, changing the SSID to WPA3-Enterprise (CNSA) would fix the issue and allow all devices to connect to the network.
NEW QUESTION # 49
What are two advantages of splitting a larger OSPF area into a number of smaller areas? (Select two )
- A. it simplifies the configuration.
- B. It increases stability
- C. It reduces the total number of LSAs
- D. It reduces processing overhead.
- E. It extends the LSDB
Answer: B,D
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.

NEW QUESTION # 50
What is a primary benefit of BSS coloring?
- A. BSS color tags improve security by identifying rogue APs and removing them from the network.
- B. BSS color tags are applied to client devices and can reduce the threshold for interference
- C. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
- D. BSS color tags improve performance by allowing clients on the same channel to share airtime.
Answer: C
Explanation:
Explanation
BSS coloring is a mechanism that helps identify the BSS Basic Service Set. A BSS is a set of interconnected stations that can communicate with each other. BSS can be an independent BSS or infrastructure BSS. An independent BSS is an ad hoc network that does not include APs, whereas the infrastructure BSS consists of an AP and all its associated clients. on the same channel and differentiate them from other BSS on the same channel12. Each BSS is assigned a color code, which is a 6-bit value that is carried in the PHY header of the Wi-Fi frames12. By using BSS coloring, the APs and clients can reduce the threshold for interference detection and avoid unnecessary backoff or retransmissions when they detect frames from other BSS with different colors12. This can improve the spectral efficiency and throughput of the network12. The other options are incorrect because they do not describe the primary benefit of BSS coloring.

(The sensor has no cellular connection)
- A. Use the Aruba installer app on your smartphone to scan the barcode
- B. Connect the new UXI from an already installed one and adjust the initial configuration.
- C. Use the CLI via the serial cable and adjust the initial configuration.
- D. Use the UXI app on your smartphone and connect the UXI via Bluetooth
Answer: D
Explanation:
To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc.
The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth.

NEW QUESTION # 53
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. The encapsulation protocol used is GRE.
- B. The encapsulation protocol used is VXLAN.
- C. The encapsulation protocol is UDP.
- D. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
- E. On the source AOS-CX switch, the destination specified is the administrators desktop
Answer: A,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.

NEW QUESTION # 54
Describe the difference between Class of Service (CoS) and Differentiated Services Code Point (DSCP).
- A. CoS is only contained in VLAN Tag fields DSCP is in the IP Header and preserved throughout the IP packet flow
- B. CoS has much finer granularity than DSCP
- C. They are similar and can be used interchangeably.
- D. CoS is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.
Answer: A
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.

With Core-1. what is the default value for config-revision?
- A. 0
- B. 0. 0
- C. 1-0
- D. 1
Answer: A
Explanation:
The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision.

NEW QUESTION # 56
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 Enhanced security
- D. Enable Secure Mode Enhanced
Answer: C
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.
