NEW QUESTION # 26
With the Aruba CX 6000 24G switch with uplinks of 1/1/25 and what does the switch do when a client port detects a loop and the do-not-disabie parameter is used?
- A. The network analytics engine is triggered.
- B. Port status will be validated once status is cleared
- C. An event log message is created.
- D. Port status led blinks in amber with 100hz.
Answer: C
Explanation:
The correct answer is B. An event log message is created.
The do-not-disable parameter is used to prevent the switch from disabling the port when a loop is detected by the loop-protect feature. Instead, the switch will generate an event log message that indicates the port number and the VLAN ID where the loop was detected. The switch will also send a trap to the SNMP manager, if configured1.
The other options are incorrect because:
A) Port status will not be validated once status is cleared. The port will remain enabled even if a loop is detected, unless the loop-protect action is changed to tx-disable or tx-rx-disable1.
C) The network analytics engine will not be triggered by a loop detection. The network analytics engine is a feature that allows users to monitor and troubleshoot network issues using scripts and agents2.
D) Port status LED will not blink in amber with 100Hz. The port status LED will indicate the normal port status, such as link speed and activity, regardless of the loop detection3.
NEW QUESTION # 27
How is Dynamic Multicast Optimization (DMO) implemented in an HPE Aruba wireless network?
- A. The controller converts multicast streams into unicast streams.
- B. The AP uses OOS to provide equal air time for multicast traffic,
- C. DMO is configured individually tor each SSID in use in the network.
- D. DMO is configured globally for each SSID in use in the network.
Answer: C
Explanation:
Explanation
The correct answer is A. DMO is configured individually for each SSID in use in the network.
DMO is a feature that allows the AP to convert multicast streams into unicast streams over the wireless link.
This enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. DMO is configured individually for each SSID in use in the network, as different SSIDs may have different multicast requirements.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure DMO is:
Dynamic multicast optimization: Select Enabled to allow IAP to convert multicast streams into unicast streams over the wireless link. Enabling Dynamic Multicast Optimization (DMO) enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients.
The other options are incorrect because:
B: The AP does not use QoS to provide equal air time for multicast traffic. QoS is a feature that prioritizes different types of traffic based on their importance and latency sensitivity. QoS does not affect how multicast streams are transmitted over the wireless link.
C; DMO is not configured globally for each SSID in use in the network. DMO is configured individually for each SSID, as different SSIDs may have different multicast requirements.
D: The controller does not convert multicast streams into unicast streams. The AP does the conversion, as it is closer to the wireless clients and can optimize the transmission based on the client capabilities and channel conditions.
NEW QUESTION # 28
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 static route-map connected-routes" command will redistribute all static routes with a matching permit in the route map "connected-routes-
- C. The "redistribute ospf" command will redistribute routes from all OSPF V2 and V3 processes
- D. The "redistribute connected" command will redistribute all connected routes for the switch including local loopback addresses
- 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,D
Explanation:
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 # 30
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. Create a new OSPF process ID with vrf name.
- B. Attach OSPF process ID in the VRF configuration.
- C. Attach a new OSFP process ID with a custom routing table
- D. Create a new OSPF area, and attach VRF name.
Answer: A
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. Reference: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch02.html https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-ch03.html
NEW QUESTION # 31
A customer has a large number of food-producing machines
* All machines are connected via Aruba CX6200 switches in VLANs 100.110. and 120
* Several external technicians are maintaining this special equipment
What are the correct commands to ensure that no rogue DHCP server will impact the network?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Explanation
configures DHCP snooping on the switch and enables it for VLANs 100, 110, and 120. It also specifies the IP address of the authorized DHCP server and sets the ports connected to the server as trusted. This prevents any unauthorized DHCP server from providing invalid configuration data to the clients on those VLANs. Option B also enables DHCP option-82, which adds information about the switch port and VLAN to the DHCP packets, allowing for more granular control and logging of DHCP transactions.
NEW QUESTION # 32
Refer to Exhibit:
A company has deployed 200 AP-635 access points. To take advantage of the 6 GHz band, the administrator has attempted to configure a new WPA3-OWE SSID in Central but is not working as expected.
What would be the correct action to fix the issue?
- A. Change the SSID to WPA3-Enhanced Open.
- B. Change the SSID to WPA3-Enterprise (CCM).
- C. Change the SSID to WPA3-Personal.
- D. Change the SSID to WPA3-Enterprise (CNSA).
Answer: A
Explanation:
The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.
WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.
According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:
Select the Security Level from the drop-down list. The following options are available:
WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.
WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.
WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.
WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.
The other options are incorrect because:
A) WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
B) WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company's use case.
D) WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.
NEW QUESTION # 33
Which feature supported by SNMPv3 provides an advantage over SNMPv2c?
- A. Encryption
- B. Community strings
- C. GetBulk
- D. Transport mapping
Answer: A
Explanation:
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. References:

NEW QUESTION # 34
Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?
- A. Hybrid Mode
- B. Spectrum Monitor
- C. Dual Mode
- D. Air Monitor
Answer: B
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.

NEW QUESTION # 35
You are doing tests in your lab and with the following equipment specifications
* AP1 has a radio that generates a 10 dBm signal
* AP2 has a radio that generates a 11 dBm signal
* AP1 has an antenna with a gain of 9 dBi
* AP2 has an antenna with a gain of 12 dBi.
* The antenna cable for AP1 has a 2 dB loss
* The antenna cable for AP2 has a 3 dB loss
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for APT?
- A. 26 dBm
- B. 17 dBm
- C. 30 dBm
- D. -12 dBm
Answer: B
Explanation:
Explanation
The calculated Equivalent Isotropic Radiated Power (EIRP) for AP1 is 17 dBm.
EIRP is the measured radiated power of an antenna in a specific direction. It is equal to the input power to the antenna multiplied by the gain of the antenna. It can also take into account the losses in transmission line, connectors, and other components. The formula for EIRP is:
EIRP = P + G - L
where P is the output power of the radio, G is the gain of the antenna, and L is the loss of the cable and connectors.
For AP1, we have:
P = 10 dBm G = 9 dBi L = 2 dB
Therefore,
EIRP = 10 + 9 - 2 EIRP = 17 dBm

NEW QUESTION # 37
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 improve security by identifying rogue APs and removing them from the network.
- D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
Answer: D
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.

NEW QUESTION # 41
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 the keepalrve link
- B. Server 1 and Server 2 can communicate with each other via the core layer
- C. Server 1 can access the core layer on only one uplink
- D. Server 2 can access the core layer via the keepalive link
- E. Server 1 can access the core layer via both uplinks
- F. Server 2 cannot access the core layer.
Answer: B,E
Explanation:
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. References:

NEW QUESTION # 42
In AOS 10. which session-based ACL below will only allow ping from any wired station to wireless clients but will not allow ping from wireless clients to wired stations"? The wired host ingress traffic arrives on a trusted port.
- A. ip access-list session pingFromWired user any svc-icmp deny any any svc-icmp permit
- B. ip access-list session pingFromWired any any svc-icmp permit user any svc-icmp deny
- C. ip access-list session pingFromWired any user any permit
- D. ip access-list session pingFromWired any any svc-icmp deny any user svc-icmp permit
Answer: D
Explanation:
A session-based ACL is applied to traffic entering or leaving a port or VLAN based on the direction of the session initiation. To allow ping from any wired station to wireless clients but not vice versa, a session-based ACL should be used to deny icmp echo traffic from any source to any destination, and then permit icmp echo-reply traffic from any source to user destination. The user role represents wireless clients in AOS 10.

NEW QUESTION # 43
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. RPVST+
- C. MAC tables
- D. UDLD
Answer: C
Explanation:
The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B. MAC tables.
The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1.
One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination2. The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states2.
