NEW QUESTION # 39
your customer has asked you to assign a switch management role for a new user The customer requires the user role to View switch configuration information and have access to the PUT and POST meth0ds for REST API.
Which default AOS-CX user role meets these requirements?
- A. sysops
- B. helpdesk
- C. auditors
- D. administrators
Answer: A
Explanation:
Explanation
The correct answer is C. sysops.
The sysops user role is a predefined role that allows users to view switch configuration information and have access to the PUT and POST methods for REST API. The sysops user role can also use the PATCH and DELETE methods for REST API, but not for all resources. The sysops user role is suitable for users who need to perform system operations on the switch, such as backup, restore, upgrade, or reboot.
According to the AOS-CX REST API Reference basics1, one of the predefined user roles is:
sysops: Users with this role can view switch configuration information and have access to the PUT and POST methods for REST API. They can also use the PATCH and DELETE methods for REST API, but not for all resources. Users with this role can perform system operations on the switch, such as backup, restore, upgrade, or reboot.
The other options are incorrect because:
A: administrators: Users with this role have full access to all switch configuration information and all REST API methods. This role is more than what the customer requires.
B: auditors: Users with this role can only view switch configuration information and have access to the GET method for REST API. They cannot use the PUT and POST methods for REST API.
D: helpdesk: Users with this role can view switch configuration information and have access to the GET method for REST API. They can also use the PATCH method for REST API, but only for a limited set of resources. They cannot use the PUT and POST methods for REST API.

With Core-1. what is the default value for config-revision?
- A. 0. 0
- B. 0
- C. 1-0
- D. 1
Answer: B
Explanation:
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. References:

NEW QUESTION # 41
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. Ethernet over IP (EolP)
- B. EVPN-VXLAN
- C. Static VXLAN
- D. Generic Routing Encapsulation (GRE)
Answer: B
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 # 42
You are troubleshooting an issue with a pair of Aruba CX 8360 switches configured with VSX Each switch has multiple VRFs. You need to find the IP address of a particular client device with a known MAC address You run the "show arp" command on the primary switch in the pair but do not find a matching entry for the client MAC address.
The client device is connected to an Aruba CX 6100 switch by VSX LAG.
Which action can be used to find the IP address successfully?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
The show arp command displays the ARP table for a specific VRF or all VRFs on the switch. The ARP table contains the IP address to MAC address mappings for hosts that are directly connected to the switch or reachable through a gateway. If the client device is connected to another switch by VSX LAG, the ARP entry for the client device will not be present on the primary switch unless it has communicated with it recently.
Therefore, to find the IP address of the client device, the administrator should run the show arp command on the secondary switch in the VSX pair, specifying the VRF name that contains the client device's subnet.

NEW QUESTION # 43
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. SVI with vsx-sync
- B. VRRP
- C. Active-Active VRRP
- D. Active Gateway
Answer: D
Explanation:
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. References:

- A. int 1/1/1-1/1/24. loop-guard
- B. int 1/1/1-1/1/28. loop-protect
- C. int 1/1/1-1/1/28. loop-guard
- D. int 1/1/1-1/1/24, loop-protect
Answer: D
Explanation:
Explanation
The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.
NEW QUESTION # 46
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. copied over the ISL link for an optimized path.
- C. Active Gateway can once MSTP instances are created for VLAN load sharing.
- D. Sixteen different VMACs are supported total as shared.
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 # 47
You need to have different routing-table requirements with Aruba CX 6300 VSF configuration Assuming the correct layer-2 VLAN already exists how would you create a new OSPF configuration for a separate routing table?
- A. Attach OSPF process ID in the VRF configuration.
- B. Create a new OSPF area, and attach VRF name.
- C. Attach a new OSFP process ID with a custom routing table
- D. Create a new OSPF process ID with vrf name.
Answer: D
Explanation:
Explanation
To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF. References:

NEW QUESTION # 49
What is a primary benefit of BSS coloring?
- A. BSS color tags are applied to client devices and can reduce the threshold for interference
- B. BSS color tags improve performance by allowing clients on the same channel to share airtime.
- C. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
- D. BSS color tags improve security by identifying rogue APs and removing them from the network.
Answer: C
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.
NEW QUESTION # 50
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. dual control plane provides better resiliency
- B. faster MSTP converge processing
- C. stacked data-plane
- D. dual Aruba AP LAN port connectivity for PoE redundancy
Answer: A
Explanation:
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.

NEW QUESTION # 51
In an ArubaOS 10 architecture using an AP and a gateway, what happens when a client attempts to join the network and the WLAN is configured with OWE?
- A. The Gateway will not respond.
- B. RADIUS protocol is utilized.
- C. Authentication information is not exchanged
- D. No encryption is applied.
Answer: C
Explanation:
This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE.

NEW QUESTION # 52
What does the 802.3bz standard describe?
- A. AP directed roaming between APs
- B. 60 GHz P2P Wi-Fi
- C. 2.5Gb and 5Gb Ethernet ports
- D. 60 W and 90W PoE
Answer: C
Explanation:
802.3bz is a standard for Ethernet over twisted pair at speeds of 2.5 and 5 Gbit/s. These use the same cabling as the ubiquitous Gigabit Ethernet, yet offer higher speeds. The resulting standards are named 2.5GBASE-T and 5GBASE-T.
Option A: 2.5Gb and 5Gb Ethernet ports
This is because option A shows how to identify the speed of an Ethernet port based on its name and the standard it supports. A port that supports 2.5GBASE-T or 5GBASE-T is a multi-gigabit port that can operate at speeds of up to 2.5 Gbit/s or 5 Gbit/s over twisted pair cables23.
Therefore, option A is correct.

NEW QUESTION # 53
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 a remote access point.
- B. The AP is an outdoor access point.
- C. The AP is using a directional antenna.
- D. The AP is configured in Mesh mode
Answer: C
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 # 54
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 outbound ACL on the user VLAN allowing temp echo-reply traffic toward the IT management VLAN
- B. Apply an inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
- C. Apply an outbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
- D. Apply an inbound ACL on the user VLAN denying icmp echo traffic toward the IT management VLAN
Answer: D
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.

NEW QUESTION # 55
Which feature supported by SNMPv3 provides an advantage over SNMPv2c?
- A. Transport mapping
- B. GetBulk
- C. Community strings
- D. Encryption
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.

NEW QUESTION # 57
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
Two parts of the solution for these requirements are Option C and Option E.
Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface1.
Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24. This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list2.
Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.
Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.
Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.
NEW QUESTION # 58
Your customer is interested in hearing more about how roles can help keep consistent policy enforcement in a distributed overlay fabric How would you explain this concept to them''
- A. Role-based policies enhance User Based Tunneling across the campus network and the policy traffic is protected with iPsec
- B. Group Based Policy ID is applied on ingress VTEP after device authentication and policy is enforced on egress VTEP
- C. Role-based policies are tied to IP addresses which have an advantage over IP-based policies and role names are sent between VTEPs
- D. Group Based Policy ID is applied on egress VTEP after device authentication and policy is enforced on ingress VTEP
Answer: B
Explanation:
This is the correct explanation of how roles can help keep consistent policy enforcement in a distributed overlay fabric. Roles are used to assign group based policy IDs (GBPs) to devices after they authenticate with ClearPass or a local database. GBPs are then used to tag the traffic from the devices and send them to the ingress VTEP, which applies the GBP on the VXLAN header. The egress VTEP then enforces the policy based on the GBP and the destination device. The other options are incorrect because they either do not describe the correct sequence of events or do not use the correct terms.
