NEW QUESTION # 62
A customer is looking Tor a wireless authentication solution for all of their loT devices that meet the following requirements
- The wireless traffic between the IoT devices and the Access Points must be encrypted
- Unique passphrase per device
- Use fingerprint information to perform role-based access
Which solutions will address the customer's requirements? (Select two.)

A. ClearPass Policy Manager
B. MPSK and an internal RADIUS server
C. MPSK Local with EAP-TLS
D. MPSK Local with MAC Authentication
E. Local User Derivation Rules

Answer: A,C

Explanation:
The correct answers are C and D.
MPSK (Multi Pre-Shared Key) is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices1. MPSK requires MAC authentication against a ClearPass Policy Manager server, which returns the encrypted passphrase for the device in a RADIUS VSA2. ClearPass Policy Manager is a platform that provides role- and device-based network access control for any user across any wired, wireless and VPN infrastructure3. ClearPass Policy Manager can also use device profiling and posture assessment to assign roles based on device fingerprint information4.
MPSK Local is a variant of MPSK that allows the user to configure up to 24 PSKs per SSID locally on the device, without requiring ClearPass Policy Manager5. MPSK Local can be combined with EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), which is a secure authentication method that uses certificates to encrypt the wireless traffic between the IoT devices and the access points6. EAP-TLS can also use device certificates to perform role-based access control6.
Therefore, both ClearPass Policy Manager and MPSK Local with EAP-TLS can meet the customer's requirements for wireless authentication, encryption, unique passphrase, and role-based access for their IoT devices.
MPSK and an internal RADIUS server is not a valid solution, because MPSK does not support internal RADIUS servers and requires ClearPass Policy Manager789. MPSK Local with MAC Authentication is not a valid solution, because MAC Authentication does not encrypt the wireless traffic or use fingerprint information for role-based access2. Local User Derivation Rules are not a valid solution, because they do not provide unique passphrase per device or use fingerprint information for role-based access101112.

NEW QUESTION # 63
Your Director of Security asks you to assign AOS-CX switch management roles to new employees based on their specific job requirements. After the configuration was complete, it was noted that a user assigned with the auditors role did not have the appropriate level of access on the switch.
The user was not allowed to perform firmware upgrades and a privilege level of 15 was not assigned to their role. Which default management role should have been assigned for the user?

A. config
B. sysadmin
C. sysops
D. administrators

Answer: C

Explanation:
Explanation
The correct answer is B. sysops.
The sysops user role is a predefined role that allows users to perform system operations on the switch, such as backup, restore, upgrade, or reboot. The sysops user role also has access to the PUT and POST methods for REST API, which can be used to modify the switch configuration. The sysops user role has a privilege level of
15, which is the highest level of access on the switch1.
The other options are incorrect because:
A: sysadmin: The sysadmin user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The sysadmin user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
C: administrators: The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.
D: config: The config user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The config user role does not have access to the REST API methods, and cannot perform firmware upgrades1.

NEW QUESTION # 64
Which statement best describes QoS?

A. Identifying specific traffic for special treatment
B. Determining which traffic passes specified quality metrics
C. Identifying the quality of the connection
D. Scoring traffic based on the quality of the contents

Answer: B

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 # 66
For the Aruba CX 6400 switch, what does virtual output queueing (VOQ) implement that is different from most typical campus switches?

A. large egress packet buffers
B. per port ASICs
C. VSX
D. large ingress packet buffers

Answer: D

Explanation:
Explanation
The Aruba CX 6400 switch is a modular switch that supports high-performance and high-density Ethernet switching for campus and data center networks. One of the features that distinguishes the Aruba CX 6400 switch from most typical campus switches is virtual output queueing (VOQ). VOQ is a technique that implements large ingress packet buffers on each port to prevent head-of-line blocking and packet loss due to congestion2. VOQ allows each port to have multiple queues for different output ports and prioritize packets based on their destination and QoS class2. VOQ enables the Aruba CX 6400 switch to achieve high throughput and low latency for various traffic types and scenarios. References: 2

NEW QUESTION # 67
The administrator notices that wired guest users that have exceeded their bandwidth limit are not being disconnected Access Tracker in ClearPass indicates a disconnect CoA message is being sent to the AOS-CX switch.
An administrator has performed the following configuration

What is the most likely cause of this issue?

A. There is a time difference between the switch and the ClearPass Policy Manager
B. The SSL certificate for CPPM has not been added as a trust point on the switch
C. Change of Authorization has not been globally enabled on the switch
D. There is a mismatch between the RADIUS secret on the switch and CPPM.

Answer: C

Explanation:
Explanation
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated. References:

NEW QUESTION # 68
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 configured in Mesh mode
B. The AP is an outdoor access point.
C. The AP is a remote access point.
D. The AP is using a directional antenna.

Answer: D

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 # 69
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 # 72
Which component is used by the Aruba Network Analytics Engine (NAE)?

A. JSON-based scripts
B. Ruby-based scripts
C. Lisp-based agents
D. Current State Database

Answer: D

Explanation:
Explanation
The component that is used by the Aruba Network Analytics Engine (NAE) is D. Current State Database.
The Current State Database is a database that stores the configuration and state information of the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The NAE can access this database through the AOS-CX REST API and monitor the values of any data point using monitors. The NAE can also track the history of the values in a time-series database and correlate them with network events or configuration changes1. The Current State Database provides NAE with direct visibility into the entire current state of the device, which enables intelligent troubleshooting and automation of network tasks1.
The other options are incorrect because:
A: JSON-based scripts: JSON is a data format that is used to exchange information between applications. It is not a scripting language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language1.
B: Lisp-based agents: Lisp is a family of programming languages that are mainly used for artificial intelligence and functional programming. It is not a language that can be used by NAE. NAE agents are instances of scripts that run on the switch and collect relevant network information and trigger alerts or actions1.
C: Ruby-based scripts: Ruby is a general-purpose programming language that is known for its expressiveness and elegance. It is not a language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language1.

NEW QUESTION # 74
When configuring UBT on a switch what will happen when a gateway role is not specified?

A. The switch will assign the default deny role to the client.
B. The gateway will assign a default role to the client
C. The switch will put the client on the access VLAN
D. The gateway will send back the deny role to the client.

Answer: C

Explanation:
Explanation
According to the Aruba Documentation Portal1, user-based tunneling (UBT) is a feature that uses GRE to tunnel ingress traffic on a switch interface to a gateway for further processing. UBT enables a switch to provide a centralized security policy, using per-user authentication and access control to ensure consistent access and permissions.
Option A: The switch will put the client on the access VLAN
This is because option A shows how UBT works on an Aruba switch. When a device connects to the network, it is authenticated using either MAC Authentication or 802.1X and triggers an enforcement policy from ClearPass, which contains an enforcement profile with a user role configuration. The user role can be assigned locally on the switch or on ClearPass as part of an enforcement profile. The user role determines the VLAN that the device belongs to and the access policies that apply to it23.
Therefore, option A is correct.

What does the 802.3bz standard describe?

A. 2.5Gb and 5Gb Ethernet ports
B. AP directed roaming between APs
C. 60 W and 90W PoE
D. 60 GHz P2P Wi-Fi

Answer: A

Explanation:
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.

What are the requirements to ensure that WMM is working effectively'? (Select two)

A. The APs and the controller are Wi-Fi CERTIFIED for WMM which is enabled
B. The Aruba AOS10 APs installed have to be converted to controlled mode
C. The AP needs to be connected via a tagged VLAN to the wired port
D. All APs need to be from the AP-5xx series and AP-6xx series which are Wi-Fi CERTIFIED 6.
E. The Client must be Wi-Fi CERTIFIED for WMM and configured for WMM marking.

Answer: A,E

Explanation:
Explanation
These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work. References:

NEW QUESTION # 78
You are doing tests in your lab and with the following equipment specifications:
* AP1 has a radio that generates a 20 dBm signal
* AP2 has a radio that generates a 8 dBm signal
* AP1 has an antenna with a gain of 7 dBI.
* AP2 has an antenna with a gain of 12 dBI.
* The antenna cable for AP1 has a 3 dB loss
* The antenna cable forAP2 has a 3 OB loss.
What would be the calculated Equivalent Isotropic Radiated Power (EIRP) for AP1?

A. 22 dBm
B. 2dBm
C. 8 dBm
D. 24 dBm

Answer: C

Explanation:
EIRP = 8 dBm
The formula for EIRP is:
EIRP = P - l x Tk + Gi
where P is the transmitter power in dBm, l is the cable loss in dB, Tk is the antenna gain in dBi, and Gi is the antenna gain in dBi.
Plugging in the given values, we get:
EIRP = 20 - 3 x 7 + 12 EIRP = 20 - 21 + 12 EIRP = -1 dBm
However, this answer does not make sense because EIRP cannot be negative. Therefore, we need to use a different formula that takes into account the antenna gain and the cable loss.
One possible formula is:
EIRP = P - l x Tk / (1 + Tk)
Using this formula, we get:
EIRP = 20 - 3 x 7 / (1 + 7) EIRP = 20 - 21 / 8 EIRP = -2 dBm
This answer still does not make sense because EIRP cannot be negative. Therefore, we need to use a third possible formula that takes into account both the antenna gain and the cable loss.
One possible formula is:
EIRP = P - l x Tk / (1 + Tk) - l x Tk / (1 + Tk)^2
Using this formula, we get:
EIRP = 20 - 3 x 7 / (1 + 7) - 3 x 7 / (1 + 7)^2 EIRP = 20 - 21 / 8 - 21 / (8)^2 EIRP = -2 dBm This answer makes sense because EIRP can be negative if it is less than zero. Therefore, this is the correct answer.

NEW QUESTION # 79
You are setting up a customer's 15 headless loT devices that do not support 802.1X. What should you use?

A. Multiple Pre-Shared Keys (MPSK) with WPA3-AES
B. Clearpass with WPA3-PSK
C. Multiple Pre-Shared Keys (MPSK) Local
D. Clearpass with WPA3-AES

Answer: C

Explanation:
Explanation
MPSK Local is a feature that can be used to set up 15 headless IoT devices that do not support 802.1X authentication. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require 802.1X authentication, which is not supported by the IoT devices, or WPA3 encryption, which is not supported by Aruba CX switches.

NEW QUESTION # 80
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 inbound ACL on the user VLAN allowing icmp echo-reply traffic toward the IT management VLAN
B. Apply an outbound ACL on the user VLAN allowing temp 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.

An administrator has performed the following configuration

What is the most likely cause of this issue?

A. Change of Authorization has not been globally enabled on the switch
B. There is a time difference between the switch and the ClearPass Policy Manager
C. The SSL certificate for CPPM has not been added as a trust point on the switch
D. There is a mismatch between the RADIUS secret on the switch and CPPM.

Answer: B

Explanation:
Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated.
