Which standard supported by some Aruba APs can enable a customer to accurately locate wireless client devices within a few meters?
- A. 802.11k
- B. 802.11W
- C. 802.11r
- D. 802.11mc
Answer: D
Explanation:
The standard that is supported by some Aruba APs and can enable a customer to accurately locate wireless client devices within a few meters is 802.11mc.
802.11mc is an IEEE standard that enables computing devices to measure the distance to nearby Wi- Fi access points using a technique called Fine Timing Measurement (FTM). FTM uses precise timestamps to calculate the round-trip time of Wi-Fi frames between the device and the access point, and then converts it to a distance estimate. By using multiple access points and triangulation methods, the device can determine its location with high accuracy. According to the Aruba document 802.11mc Support, this feature is supported on 500 Series, 510 Series, 530 Series, 550 Series, 560 Series and 570 Series access points. These APs act as FTM responders to time measurement queries sent from a client. To configure the AP to send FTM responses, you need to enable the ftm-responder-enable parameter in the WLAN SSID profile.

What does the 802.3bz standard describe?
- A. 2.5Gb and 5Gb Ethernet ports
- B. AP directed roaming between APs
- C. 60 GHz P2P Wi-Fi
- D. 60 W and 90W PoE
Answer: A
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 # 57
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 8325 switches Set the trap-option
- C. Configure spanning tree on the Aruba CX 6200 and CX 6300 switches No trap option is needed
- 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:
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 # 59
Which statements are true regarding a VXLAN implementation on Aruba Switches? (Select two.)
- A. VTEPs encapsulate and decapsulate VXLAN traffic
- B. They are only available for datacenter switches (CX 8k, 9k,10k)
- C. VNIs encapsulate and decapsulate VXLAN traffic
- D. All Aruba CX switches support VXLAN.
- E. MTU size must be increased beyond the default
Answer: C,E
Explanation:
Option A: MTU size must be increased beyond the default
This is because option A shows how to configure the MTU size for VXLAN tunnels on Aruba switches using the interface command and the vxlan command. The MTU size must be increased beyond the default value of 1500 bytes to accommodate the VXLAN header and payload2.
Therefore, option A is true regarding a VXLAN implementation on Aruba switches.
Option B: VNIs encapsulate and decapsulate VXLAN traffic
This is also true regarding a VXLAN implementation on Aruba switches. VNIs are used to encapsulate and decapsulate VXLAN traffic between two devices, such as a switch and a server. VNIs are also used to map VXLAN tunnels to overlay networks3.
Therefore, option B is also true regarding a VXLAN implementation on Aruba switches.
VXLAN is a Layer 2 encapsulation technology that substitutes the usage of VLAN numbers to label Ethernet broadcast domains with VXLAN numbers. VXLAN supports 224 Ethernet broadcast domains or VXLAN numbers. A VXLAN number ID is referred to as VNI. There is a one-to-one relationship between an Ethernet broadcast domain and a VNI. A single Ethernet broadcast domain can't have more than one VNI.
NEW QUESTION # 60
A customer is using a legacy application that communicates at layer-2. The customer would like to keep this application working to a remote site connected via layer-3 All legacy devices are connected to a dedicated Aruba CX 6200 switch at each site.
What technology on the Aruba CX 6200 could be used to meet this requirement?
- A. Ethernet over IP (EolP)
- B. Generic Routing Encapsulation (GRE)
- C. Static VXLAN
- D. Inclusive Multicast Ethernet Tag (IMET)
Answer: D
Explanation:
VXLAN is a technology that can be used to meet the requirement of using a legacy application that communicates at layer-2 across a layer-3 network. Static VXLAN is a feature that allows the creation of layer-2 overlay networks over a layer-3 underlay network using VXLAN tunnels. Static VXLAN does not require any control plane protocol or VTEP discovery mechanism, and can be configured manually on the Aruba CX 6200 switches. The other options are incorrect because they either do not support layer-2 communication over layer-3 network or are not supported by Aruba CX 6200 switches.

You need to drop excessive broadcast traffic on an ingress port or an ArubaOS-CX switch. What is the best feature to use for this task?
- A. QoS shaping
- B. DWRR queuing
- C. Strict queuing
- D. Rate limiting
Answer: D
Explanation:
Explanation
According to the Aruba Documentation Portal1, the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.
This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second. Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port

NEW QUESTION # 63
With the Aruba CX 6100 48G switch with uplinks of 1/1/47 and 1/1/48.
How do you automate the process of resuming the port operational state once a loop on a client port is cleared?
- A. Configure global loop-protect disable timer.
- B. Configure int 1/1/1-1/1/52 loop-protect disable timer.
- C. Configure int 1/1/1-1/1/46 loop-protect re-enable-timer.
- D. Configure global loop-protect re-enable-timer.
Answer: D
Explanation:
In the Aruba CX 6100 48G switch, to automate the resumption of the operational state of a client port once a loop is cleared, the loop protection re-enable timer should be used. This timer setting allows for the automatic re-enabling of the port after a specified time once it has been automatically disabled due to the detection of a loop.
By configuring the global loop-protect re-enable timer, the process of automatically resuming the port's operation can be automated across the entire switch. When any port detects a loop and then the loop is cleared, the port will automatically return to operational status after the set time.
NEW QUESTION # 64
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. Generic Routing Encapsulation (GRE)
- C. EVPN-VXLAN
- D. Static VXLAN
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 # 65
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: A,C
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 # 70
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 is UDP.
- B. On the source AOS-CX switch, the destination specified is the switch to which the administrator's desktop is connected
- C. The encapsulation protocol used is VXLAN.
- D. The encapsulation protocol used is GRE.
- E. On the source AOS-CX switch, the destination specified is the administrators desktop
Answer: D,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.

Using Aruba best practices what should be enabled for visitor networks where encryption is needed but authentication is not required?
- A. Opportunistic Wireless Encryption
- B. Open Network Access
- C. Wi-Fi Protected Access 3 Enterprise
- D. Wired Equivalent Privacy
Answer: A
Explanation:
Opportunistic Wireless Encryption (OWE) is a feature that provides encryption for open wireless networks without requiring authentication. OWE uses an enhanced version of the 4-way handshake to establish a pairwise key between the client and the AP, which is then used to encrypt the wireless traffic using WPA2 or WPA3 protocols. OWE can be used for visitor networks where encryption is needed but authentication is not required.References:https://www.arubanetworks.com/assets/tg/TG_OWE.pdf
NEW QUESTION # 72
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 can access the core layer via both uplinks
- B. Server 2 can access the core layer via the keepalive link
- C. Server 1 and Server 2 can communicate with each other via the core layer
- D. Server 1 can access the core layer on only one uplink
- E. Server 2 cannot access the core layer.
- F. Server 1 can access the core layer via the keepalrve link
Answer: A,C
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 thatare not possible or not relevant to the question.References:
