What is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports?
- A. Implement a control plane ACL to limit access to approved IPs and/or subnets
- B. Disable all management services on the default VRF.
- C. Manually enable Enhanced Security Mode from a console session.
- D. Create a dedicated management VRF, and assign the management port to it.
Answer: D
Explanation:
Explanation
This is an Aruba-recommended best practice for hardening that only applies to Aruba CX 6300 series switches with dedicated management ports. A dedicated management port is a physical port that is used exclusively for out-of-band management access to the switch. A dedicated management VRF is a virtual routing and forwarding instance that isolates the management traffic from other traffic on the switch. By creating a dedicated management VRF and assigning the management port to it, the administrator can enhance the security and performance of the management access to the switch. The other options are incorrect because they either do not apply to switches with dedicated management ports or do not follow Aruba-recommended best practices.

NEW QUESTION # 30
What is a primary benefit of BSS coloring?
- A. BSS color tags are applied to WI-Fi channels and can reduce the threshold tor interference
- B. BSS color tags improve performance by allowing APS on the same channel to be farther apart
- C. BSS color tags are applied on the wireless controllers and can reduce the threshold for interference_
- D. BSS color tags improve security by identifying rogue APS and tagging them as threats.
Answer: A
Explanation:
Explanation
The primary benefit of BSS coloring is D. BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference.
BSS coloring is a mechanism that allows Wi-Fi 6 devices to mark each frame with a color code that identifies the BSS (Basic Service Set) it belongs to. This helps differentiate between frames from different BSSs that share the same channel and avoid unnecessary collisions and backoffs. BSS coloring also introduces an adaptive threshold for interference, which means that Wi-Fi 6 devices can adjust the signal strength value that determines whether a channel is busy or not based on the current network environment. This allows for more efficient use of spectrum and higher throughput in dense scenarios12.

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. e ip="img_94.jpg"></e>
- D.
Answer: D
Explanation:
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. References:

NEW QUESTION # 33
Which statement best describes QoS?
- A. Identifying the quality of the connection
- B. Scoring traffic based on the quality of the contents
- C. Identifying specific traffic for special treatment
- D. Determining which traffic passes specified quality metrics
Answer: D
Explanation:
QoS stands for Quality of Service and is a mechanism that allows network devices to prioritize and differentiate traffic based on certain criteria, such as application type, source, destination, etc3. QoS involves identifying specific traffic for special treatment and applying policies and actions to improve its performance or meet certain service level agreements (SLAs)3. QoS can help network devices to manage congestion, delay, jitter, packet loss, bandwidth allocation, etc., for different types of traffic3. QoS can be implemented at various layers of the network stack and across different network domains.

NEW QUESTION # 34
By default, Best Effort is higher priority than which priority traffic type?
- A. Network Control
- B. Internet Control
- C. Background
- D. All queues
Answer: C
Explanation:
This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency). A typical example would be peer-to-peer and email applications2. Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network3.
Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.

NEW QUESTION # 35
Using Aruba best practices what should be enabled for visitor networks where encryption is needed but authentication is not required?
- A. Wired Equivalent Privacy
- B. Open Network Access
- C. Wi-Fi Protected Access 3 Enterprise
- D. Opportunistic Wireless Encryption
Answer: D
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. Reference: https://www.arubanetworks.com/assets/tg/TG_OWE.pdf
NEW QUESTION # 36
When setting up an Aruba CX VSX pair, which information does the Inter-Switch Link Protocol configuration use in the configuration created?
- A. hello interval is disabled by default
- B. hello interval is based on the value set by dead interval
- C. hello interval is 1s by default
- D. hello interval 100ms by default
Answer: C
Explanation:
The reason is that the Inter-Switch Link Protocol (ISLP) is a protocol that enables VSX stack join and synchronization between two VSX peer switches. ISLP uses a hello interval to exchange control messages between the switches.
The hello interval is a parameter that specifies the time interval between sending hello messages. The default value of the hello interval is 1 second. The hello interval can be configured from 1 second to 10 seconds.

NEW QUESTION # 37
Review the exhibit.
You are troubleshooting an issue with a 10 102.39 0/24 subnet which is also VLAN 1000 used Tor wireless clients on a pair of Aruba CX 8360 switches The subnet SVI is configured on the 8360 pair, and the DHCP server is a Microsoft Windows Server 2022 Standard with an IP address of 10 200 1.100. The 10.102.250.0/24 subnet is used for switch management.
A large number of DHCP requests are failing You are observing sporadic DHCP behavior across clients attached to the CX 6100 switch.
Which action may help fix the issue?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
Option C is the only action that configures the DHCP relay on the SVI of VLAN 1000 on the CX 8360 switches. DHCP relay is a feature that allows a switch to forward DHCP requests from clients in one subnet to a DHCP server in another subnet. DHCP relay is required when the DHCP server and the clients are not in the same broadcast domain1.
Option C uses the following commands:
* interface vlan 1000: This command enters the interface configuration mode for the SVI of VLAN 1000, which has an IP address of 10.102.39.1/24 and is used for wireless clients.
* ip helper-address vrf default 10.200.1.100: This command configures the IP address of the DHCP server as a helper address for the SVI, which means that the switch will forward DHCP requests from clients on VLAN 1000 to this address. The vrf default parameter indicates that the SVI and the DHCP server are in the same VRF.
NEW QUESTION # 38
Your customer currently has Iwo (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution. What would you explain regarding the Aruba CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?
- A. VSX will select the MAC address from a node that is the lower ID.
- B. VSX will select the MAC address from a node that is a higher ID.
- C. Configure vMAC on the Primary VSX node under VSX to retain MAC after hardware replacement.
- D. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.
Answer: D
Explanation:
The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node. The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID. The system-mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct.

NEW QUESTION # 41
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 SVI for a separate routing table?
- A. Create a new SVI and use attach command.
- B. Create a new VLAN. and attach the routing table to it
- C. create a new VLAN, and attach the VRF to it.
- D. Create a new routing table, and attach VLANS to it
Answer: A
Explanation:
The correct answer is C. Create a new SVI and use attach command.
To create a new SVI for a separate routing table, you need to use the attach command to associate the SVI with a VRF (Virtual Routing and Forwarding) instance. A VRF is a logical entity that allows multiple routing tables to coexist on the same switch. Each VRF has its own set of interfaces, routing protocols, and routes that are isolated from other VRFs.
According to the AOS-CX Virtual Switching Framework (VSF) Guide1, one of the steps to configure VRF-aware VSF is:
Configure the VRFs on each member switch and assign the SVIs to the respective VRFs using the attach command. For example:
switch(config)# vrf red
switch(config-vrf)# exit
switch(config)# interface vlan 10
switch(config-if-vlan)# ip address 10.1.1.1/24
switch(config-if-vlan)# attach vrf red
The above commands create a VRF named red and assign VLAN 10 SVI to it. The SVI has an IP address of 10.1.1.1/24.
The other options are incorrect because:
A) You cannot attach a VRF to a VLAN directly. You need to create an SVI for the VLAN and then attach the VRF to the SVI.
B) You cannot create a new routing table manually. You need to create a VRF and then use routing protocols or static routes to populate the routing table for the VRF.
D) You cannot attach a routing table to a VLAN directly. You need to create an SVI for the VLAN and then attach a VRF that has a routing table associated with it.
NEW QUESTION # 42
What steps are part of the Key Management workflow when a wireless device is roaming from AP1 to AP2? (Select two.)
- A. A client associates and authenticates with the AP2 after roaming from AP1
- B. The Key Management service receives from AirMatch a list of all AP2's neighbors
- C. The Key Management service receives a list of all AP1 s neighbors from AirMatch.
- D. AP1 will cache the client's information and send it to the Key Management service
- E. The Key Management service then generates R1 keys for AP2's neighbors.
Answer: D,E
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.

NEW QUESTION # 43
Which statements are true about VSX LAG? (Select two.)
- A. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
- B. Outgoing traffic is preferentially switched to local members of the LAG.
- C. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.
- D. The total number of configured links may not exceed 8 for the pair or 4 per switch
- E. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
Answer: B,E
Explanation:
Explanation
VSX LAG is a feature that allows a pair of Aruba CX switches to form a multichassis LAG with a downstream or upstream device. VSX LAG provides link redundancy and load balancing across the two switches. Outgoing traffic from the VSX pair to the peer device is switched to a port based on a hashing algorithm that considers various parameters such as source and destination MAC addresses, IP addresses, ports, etc. The hashing algorithm may select a port that belongs to either switch in the pair, depending on the traffic characteristics1. However, outgoing traffic is preferentially switched to local members of the LAG, meaning that each switch tries to use its own ports first before using the ISL link to send traffic to the other switch's ports2. This reduces the ISL utilization and improves performance. References: 1
