NEW QUESTION # 82
Using Aruba best practices what should be enabled for visitor networks where encryption is needed but authentication is not required?
- A. Wi-Fi Protected Access 3 Enterprise
- B. Opportunistic Wireless Encryption
- C. Open Network Access
- D. Wired Equivalent Privacy
Answer: B
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 # 84
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 int 1/1/1-1/1/52 loop-protect disable timer.
- B. Configure global loop-protect re-enable-timer.
- C. Configure int 1/1/1-1/1/46 loop-protect re-enable-timer.
- D. Configure global loop-protect disable timer.
Answer: C
Explanation:
Loop protection is a feature that detects and prevents loops in layer 2 networks. Loop protection can be enabled on ports, LAGs, or VLANs. When loop protection is enabled, the switch sends periodic loop protection messages on the interface and expects to receive them back. If a loop protection message is received back on the same interface, it indicates a loop and the switch takes an action to disable the interface or block trafficon it3. The loop-protect re-enable-timer command is used to configure the length of time the switch waits before re-enabling an interface that was disabled due to loop detection. The default value is 0, which means that the interface remains disabled until manually re-enabled3. To automate the process of resuming the port operational state once a loop on a client port is cleared, the loop-protect re-enable-timer command can be used with a non-zero value on the interface range that includes the client ports3. Therefore, answer C is correct.

Refer to Exhibit:
With Access-1, What needs to be identically configured With MSTP to load-balance VLANS?
- A. spanning-tree Cist mapping
- B. Spanning-tree bpdu-guard setting
- C. Spanning-tree root-guard setting
- D. Spanning-tree instance vlan mapppjng
Answer: D
Explanation:
Explanation
The correct answer is B. Spanning-tree instance VLAN mapping.
To load-balance VLANs with MSTP, you need to configure the same VLAN-to-instance mapping on all switches in the same MST region. This means that you need to assign different VLANs to different MST instances, and then adjust the spanning tree parameters (such as priority, cost, or port role) for each instance to achieve the desired load balancing. For example, you can make one switch the root for instance 1 and another switch the root for instance 2, and then map half of the VLANs to instance 1 and the other half to instance 2.
According to the Cisco document Understand the Multiple Spanning Tree Protocol (802.1s), one of the steps to configure MST is:
* Split your set of VLANs into more instances and configure different MST settings for each of these instances. In order to easily achieve this, elect Bridge D1 to be the root for VLANs 501 through 1000, and Bridge D2 to be the root for VLANs 1 through 500. These statements are true for this configuration:
Switch D1(config)#spanning-tree mst configuration
Switch D1(config-mst)#instance 1 vlan 501-1000
Switch D1(config-mst)#exit
Switch D1(config)#spanning-tree mst 1 priority 0
Switch D2(config)#spanning-tree mst configuration
Switch D2(config-mst)#instance 2 vlan 1-500
Switch D2(config-mst)#exit
Switch D2(config)#spanning-tree mst 2 priority 0
The above commands create two MST instances, 1 and 2, and map VLANs 501-1000 to instance 1 and VLANs 1-500 to instance 2. Then, they make switch D1 the root for instance 1 and switch D2 the root for instance 2.
The other options are incorrect because:
* A. Spanning-tree bpdu-guard setting is a security feature that disables a port if it receives a BPDU from an unauthorized device. It does not affect load balancing with MSTP.
* C. Spanning-tree CIST mapping is not a valid command. CIST stands for Common and Internal Spanning Tree, which is the spanning tree instance that runs within an MST region and interacts with other regions or non-MST switches.
* D. Spanning-tree root-guard setting is another security feature that prevents a port from becoming a root port if it receives superior BPDUs from another switch. It does not affect load balancing with MSTP.

NEW QUESTION # 89
How do you allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45?
- A. vlan trunk allowed 100 in LAG256
- B. vlan trunk add 100 in LAG256
- C. vlan trunk allowed 100 for ports 1/45 and 1/46
- D. vlan trunk add 100 in MLAG256
Answer: A
Explanation:
Explanation
To allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45, you need to use the command vlan trunk allowed 100 in LAG256. This will add VLAN 100 to the list of allowed VLANs on the trunk port LAG256, which is part of the inter-switch-link between VSX peers. The other options are incorrect because they either do not use the correct command or do not specify the correct port or VLAN.

NEW QUESTION # 90
What is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches?
- A. Central authentication and port-based tunneling of the voice traffic.
- B. Controller authentication and port-based tunneling of all traffic
- C. Switch authentication and local forwarding of the voice traffic
- D. Switch authentication and user-based tunneling of the voice traffic.
Answer: C
Explanation:
Explanation
This is the best practice for handling voice traffic with dynamic segmentation on AOS-CX switches. Dynamic segmentation is a feature that allows AOS-CX switches to tunnel user traffic to a controller or another switch based on user roles and policies. For voice traffic, it is recommended to use switch authentication and local forwarding, which means the voice devices are authenticated by the switch and their traffic is forwarded locally without tunneling. This reduces latency and jitter for voice traffic and improves voice quality. The other options are incorrect because they either use central authentication or tunneling, which are not optimal for voice traffic. References:

NEW QUESTION # 91
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. Inclusive Multicast Ethernet Tag (IMET)
- B. Ethernet over IP (EolP)
- C. Generic Routing Encapsulation (GRE)
- D. Static VXLAN
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.

NEW QUESTION # 92
A client is connecting to 802.1X SSID that has been configured in tunnel mode with the default AP- group settings.
After receiving Access-Accept from the RADIUS server, the Aruba Gateway will send Access-Accept to the AP through which tunnel?
- A. IPsec tunnel
- B. GRE tunnel
- C. Split tunnel
- D. PAR tunnel
Answer: B
Explanation:
According to the Aruba Documentation Portal1, 802.1X is a standard for port-based network access control that uses a RADIUS server to authenticate and authorize wireless clients. 802.1X can be configured in different modes, such as bridge mode, tunnel mode, or split tunnel mode. Option C: GRE tunnel This is because option C shows how to configure an SSID in tunnel mode with the default AP-group settings on an Aruba switch. In tunnel mode, all client traffic from the access points is tunneled back to the controller and the controller would in turn put the client traffic onto the network2. The GRE protocol is used to encapsulate and decapsulate the traffic between the access points and the controller3.
Therefore, option C is correct.

NEW QUESTION # 93
Which statements are true about VSX LAG? (Select two.)
- A. The total number of configured links may not exceed 8 for the pair or 4 per switch
- B. Up to 255 VSX lags can be configured on all 83xx and 84xx model switches.
- C. Outgoing traffic is switched to a port based on a hashing algorithm which may be either switch in the pair
- D. Outgoing traffic is preferentially switched to local members of the LAG.
- E. LAG traffic is passed over VSX ISL links only while upgrading firmware on the switch pair
Answer: C,D
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.

A large retail client is looking to generate a rich set of contextual data based on the location information of wireless clients in their stores Which standard uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP?
- A. 802.11ah
- B. 802.11mc
- C. 802.11be
- D. 802.11V
Answer: B
Explanation:
802.11mc is a standard that uses Round Trip Time (RTT) and Fine Time Measurements (FTM) to calculate the distance a client is from an AP. 802.11mc defines a protocol for exchanging FTM frames between an AP and a client, which contain timestamps that indicate when the frames were transmitted and received. By measuring the RTT of these frames, the AP or the client can estimate their distance based on the speed of light. The other options are incorrect because they either do not use RTT or FTM or do not exist as standards.

- A. Configure a BGP link between the core routing switch and the dedicated router and route filtering.
- B. Configure a dedicated VRF on the core routing switch and make the dedicated router the default route.
- C. Configure a new OSPF area including both the core routing switch and the dedicated router
- D. Configure Policy Based Routing (PBR) on the core routing switch for the VRF with the servers' SVI
Answer: D
Explanation:
The reason is that PBR allows you to route packets based on policies that match certain criteria, such as source or destination IP addresses, ports, protocols, etc. PBR can also be used to set metrics, next-hop addresses, or tag traffic for different routes.
NEW QUESTION # 99
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 is only used to determine CLASS of traffic DSCP is only used to differentiate between different Classes.
- C. They are similar and can be used interchangeably.
- D. CoS has much finer granularity than DSCP
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.
