NEW QUESTION # 70
A network technician has successfully connected to the employee SSID via 802 1X Which RADIUS message should you look for to ensure a successful connection?
- A. Authorized
- B. Authenticated
- C. Access-Accept
- D. Success
Answer: C
Explanation:
The RADIUS message that you should look for to ensure a successful connection via 802.1X is Access-Accept. This message indicates that the RADIUS server has authenticated and authorized the supplicant (the device that wants to access the network) and has granted it access to the network resources. The Access-Accept message may also contain additional attributes such as VLAN ID, session timeout, or filter ID that specify how the authenticator (the device that controls access to the network, such as a switch) should treat the supplicant's traffic.
The other options are not RADIUS messages because:
Authorized: This is not a RADIUS message, but a state that indicates that a port on an authenticator is allowed to pass traffic from a supplicant after successful authentication and authorization.
Success: This is not a RADIUS message, but a status that indicates that an EAP Extensible Authentication Protocol (EAP) is an authentication framework that provides support for multiple authentication methods, such as passwords, certificates, tokens, or biometrics. EAP is used in wireless networks and point-to-point connections to provide secure authentication between a supplicant (a device that wants to access the network) and an authentication server (a device that verifies the credentials of the supplicant). exchange has completed successfully between a supplicant and an authentication server.
Authenticated: This is not a RADIUS message, but a state that indicates that a port on an authenticator has received an EAP-Success message from an authentication server after successful authentication of a supplicant.
NEW QUESTION # 71
Which part of the WPA Key Hierarchy is used to encrypt and/or decrypt data''
- A. Pairwise Master Key (PMK)
- B. number used once (nonce)
- C. Key Confirmation Key (KCK)
- D. Pairwise Temporal Key (PTK)
Answer: D
Explanation:
The part of WPA Key Hierarchy that is used to encrypt and/or decrypt data is Pairwise Temporal Key (PTK). PTK is a key that is derived from PMK Pairwise Master Key (PMK) is a key that is derived from PSK Pre-shared Key (PSK) is a key that is shared between two parties before communication begins , ANonce Authenticator Nonce (ANonce) is a random number generated by an authenticator (a device that controls access to network resources, such as an AP) , SNonce Supplicant Nonce (SNonce) is a random number generated by supplicant (a device that wants to access network resources, such as an STA) , AA Authenticator Address (AA) is MAC address of authenticator , SA Supplicant Address (SA) is MAC address of supplicant using Pseudo-Random Function (PRF). PTK consists of four subkeys:
KCK Key Confirmation Key (KCK) is used for message integrity check
KEK Key Encryption Key (KEK) is used for encryption key distribution
TK Temporal Key (TK) is used for data encryption
MIC Message Integrity Code (MIC) key
The subkey that is specifically used for data encryption is TK Temporal Key (TK). TK is also known as Pairwise Transient Key (PTK). TK changes periodically during communication based on time or number of packets transmitted.
The other options are not part of WPA Key Hierarchy because:
PMK: PMK is not part of WPA Key Hierarchy, but rather an input for deriving PTK.
KCK: KCK is part of WPA Key Hierarchy, but it is not used for data encryption, but rather for message integrity check.
Nonce: Nonce is not part of WPA Key Hierarchy, but rather an input for deriving PTK.

Reference: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6790/GUID-D6EF042E-EEEF-49F7-B67E-4CAC41CCB24D.html
NEW QUESTION # 75
What are the main characteristics of the 6 GHz band?
- A. Less RF signal is absorb by objects in a 6 GHz WLAN.
- B. In North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band.
- C. The 6 GHz band is fully backward compatible with the existing bands.
- D. Low Power Devices are allowed for indoor and outdoor usage.
Answer: B
Explanation:
The main characteristic of the 6 GHz band that is true among the given options is that in North America, the 6 GHz band offers more 80 MHz channels than there are 40 MHz channels in the 5 GHz band. This characteristic provides more spectrum availability, less interference, and higher throughput for wireless devices that support Wi-Fi 6E Wi-Fi Enhanced (Wi-Fi 6E) is an extension of Wi-Fi 6 (802.11ax) standard that operates in the newly available unlicensed frequency spectrum around 6 GHz in addition to existing bands below it.
Some facts about this characteristic are:
- In North America, there are up to seven non-overlapping channels available in each of three channel widths (20 MHz, 40 MHz, and 80 MHz) in the entire unlicensed portion of the new spectrum (5925-7125 MHz). This means there are up to 21 non-overlapping channels available for Wi-Fi devices in total.
- In comparison, in North America, there are only nine non-overlapping channels available in each of two channel widths (20 MHz and 40 MHz) in the entire unlicensed portion of the existing spectrum below it (2400-2483 MHz and 5150-5825 MHz). This means there are only up to nine non-overlapping channels available for Wi-Fi devices in total.
- Therefore, in North America, there are more than twice as many non-overlapping channels available in each channel width in the new spectrum than in the existing spectrum below it.
- Specifically, there are more than twice as many non-overlapping channels available at 80 MHz width (seven) than at 40 MHz width (three) in the existing spectrum below it.
The other options are not true because:
- Less RF signal is absorbed by objects in a 6 GHz WLAN: This option is false because higher frequency signals tend to be more absorbed by objects than lower frequency signals due to higher attenuation Attenuation is a general term that refers to any reduction in signal strength during transmission over distance or through an object or medium. Therefore, RF signals in a 6 GHz WLAN would be more absorbed by objects than RF signals in a lower frequency WLAN.
- The 6 GHz band is fully backward compatible with existing bands: This option is false because Wi-Fi devices need to support Wi-Fi 6E standard to operate in the new spectrum around 6 GHz. Existing Wi-Fi devices that do not support Wi-Fi 6Estandard cannot use this spectrum and can only operate in existing bands below it.
- Low Power Devices are allowed for indoor and outdoor usage: This option is false because Low Power Indoor Devices (LPI) are only allowed for indoor usage under certain power limits and registration requirements. Outdoor usage of LPI devices is prohibited by regulatory authorities such as FCC Federal Communications Commission (FCC) is an independent agency of United States government that regulates communications by radio, television, wire, satellite, and cable across United States. However, outdoor usage of Very Low Power Devices (VLP) may be allowed under certain power limits and without registration requirements.

NEW QUESTION # 76
When using an Aruba standalone AP you select "Native VLAN" for the Client VLAN Assignment In which subnet will the client IPs reside?
- A. The same subnet as the mobility controller
- B. The same subnet as the mobility conductor
- C. The same subnet as the access point
- D. The same subnet as the Aruba ESP gateway
Answer: C
Explanation:
Explanation
When using an Aruba standalone AP, selecting "Native VLAN" for the Client VLAN Assignment means that the clients will get their IP addresses from the same subnet as the access point's IP address. This is because the access point acts as a DHCP server for the clients in this mode.

NEW QUESTION # 79
Two independent ArubaOS-CX 6300 switches with Spanning Tree (STP) settings are interconnected with two cables between ports 1/1/1 and 1/1/2 All four ports have "no shutdown" and "no routing" commands.
How will STP forward or discard traffic on these ports?
- A. The switch with the lower MAC address will discard on one port, while the switch with the higher MAC address will discard on one port
- B. The switch with the lower MAC address will forward on both ports, while the switch with the higher MAC address will forward on both ports
- C. The switch with the lower MAC address will forward on both ports, while the switch with the higher MAC address will discard on one port
- D. The switch with the lower MAC address will discard on one port, while the switch with the higher MAC address will forward on both ports
Answer: A
Explanation:
The way that STP Spanning Tree Protocol. STP is a network protocol that ensures a loop-free topology for any bridged Ethernet local area network by preventing redundant paths between switches or bridges from creating loops that cause broadcast storms, multiple frame transmission, and MAC table instability.
STP creates a logical tree structure that spans all of the switches in an extended network and blocks any redundant links that are not part of the tree from forwarding data packets3.
will forward or discard traffic on these ports is as follows:
- STP will elect a root bridge among the two switches based on their bridge IDs, which are composed of a priority value and a MAC address. The switch with the lower bridge ID will become the root bridge and will forward traffic on all its ports.
- STP will assign a role and a state to each port on both switches based on their port IDs, which are composed of a priority value and a port number. The port with the lower port ID will become the designated port and will forward traffic, while the port with the higher port ID will become the alternate port and will discard traffic.
- In this scenario, since both switches have two cables connected between ports 1/1/1 and 1/1/2, there will be two possible paths between them, creating a loop. To prevent this loop, STP will block one of these paths by discarding traffic on one of the ports on each switch.
- Assuming that both switches have the same priority value (default is 32768), the switch with the lower MAC address will have the lower bridge ID and will become the root bridge. The root bridge will forward traffic on both ports 1/1/1 and 1/1/2.
- Assuming that both ports have the same priority value (default is 128), port 1/1/1 will have a lower port ID than port 1/1/2 on both switches because it has a lower port number. Port 1/1/1 will become the designated port and will forward traffic, while port 1/1/2 will become the alternate port and will discard traffic.
- Therefore, the switch with the lower MAC address will discard traffic on one port (port 1/1/2), while the switch with the higher MAC address will also discard traffic on one port (port 1/1/2).

NEW QUESTION # 81
A hacker has altered a user's 3-Way Handshake in order to gain access to their session.
Which security mechanism would intelligently deny this traffic?
- A. Stateless firewall
- B. Access Control List (ACL)
- C. Stateful firewall
- D. Out-of-band management (00BM)
Answer: C
Explanation:
A stateful firewall would intelligently deny traffic from a hacker attempting to alter a user's 3-Way Handshake to gain access to their session. Stateful firewalls keep track of the state of active connections and can recognize if an incoming packet is part of an established session. This allows them to detect and block unauthorized access attempts that do not match the known state of a connection.

NEW QUESTION # 83
Refer to the exhibit.
In the given topology, a pair of Aruba CX 8325 switches are in a VSX stack using the active gateway.
What is the nature and behavior of the Virtual IP for the VSX pair if clients are connected to the access switch using VSX as the default gateway?
- A. Virtual IP is active on both CX switches
- B. Virtual IP uses SVI IP address synced with VSX
- C. Virtual floating IP will failover in case of a failure
- D. Virtual IP is active on the primary VSX switch
Answer: D
Explanation:
Virtual Switching Extension (VSX) is a feature that allows two Aruba CX switches to operate as a single logical device with a single control plane and data plane. VSX provides high availability, scalability, and simplified management for campus and data center networks3. In VSX, one switch is designated as the primary switch and the other as the secondary switch. The primary switch owns and responds to ARP Address Resolution Protocol. ARP is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite. requests for the virtual IP address of the VSX pair4. The virtual IP address is used as the default gateway for clients connected to the access switch. If the primary switch fails, the secondary switch takes over the virtual IP address and continues to forward traffic for the clients5.

NEW QUESTION # 84
A network technician is troubleshooting one new AP at a branch office that will not receive Its configuration from Aruba Central The other APs at the branch are working as expected The output of the 'show ap debug cloud-server command' shows that the "cloud conflg received" Is FALSE.
After confirming the new AP has internet access, what would you check next?
- A. Verify the AP can ping the device on arubanetworks.com
- B. Disable and enable activate to trigger provisioning refresh
- C. Verify the AP has a license assigned
- D. Disable and enable Aruba Central to trigger configuration refresh
Answer: B
Explanation:
When an Aruba AP is not receiving its configuration from Aruba Central, and other APs at the location are functioning normally, a common troubleshooting step is to disable and then re-enable the activation process on the AP. This action can trigger a provisioning refresh, prompting the AP to attempt to retrieve its configuration from Aruba Central again. This step is often effective in resolving communication or provisioning issues between the AP and the management platform.

NEW QUESTION # 87
A network technician at a branch office is connecting VolP phones to a newly configured AOS-CX switch. Users are complaining that voice quality is not as good as at the corporate office. Further investigation shows the local-priority value at the branch office is 1 while at the corporate office is 5.
What describes the issue regarding the default QoS behavior on the AOS-CX switch?
- A. The QoS trust is set to DSCP by default, and the VolP phone's local-priority value is mapped to 1.
- B. The QoS trust is set to CoS by default, and the VolP phone's local-priority value is mapped to 1.
- C. The QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS map entry 1.
- D. The QoS trust is set to none by default, and each VolP phone's local priority is configured for CoS map entry 0.
Answer: C
Explanation:
In an AOS-CX switch, if the QoS trust mode is not configured, it is set to none by default. The VoIP phones will mark their traffic with a local-priority value, which, if the QoS trust mode is none, will correspond to CoS map entry 1 by default. The local-priority value of 1 at the branch office likely indicates that the traffic is not being prioritized correctly compared to the corporate office, where a local-priority of 5 suggests a higher level of prioritization for voice traffic.
NEW QUESTION # 88
The noise floor measures 000000001 milliwatts, and the receiver's signal strength is -65dBm. What is the Signal to Noise Ratio?
- A. 45 dBm
- B. 35 dBm
- C. 15 dBm
- D. 25 dBm
Answer: D
Explanation:
Explanation
The signal to noise ratio (SNR) is a measure that compares the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power, often expressed in decibels (dB). A high SNR means that the signal is clear and easy to detect or interpret, while a low SNR means that the signal is corrupted or obscured by noise and may be difficult to distinguish or recover3. To calculate the SNR in dB, we can use the following formula:
SNR (dB) = Signal power (dBm) - Noise power (dBm)
In this question, we are given that the noise floor measures -90 dBm (0.000000001 milliwatts) and the receiver's signal strength is -65 dBm (0.000316 milliwatts). Therefore, we can plug these values into the formula and get:
SNR (dB) = -65 dBm - (-90 dBm) SNR (dB) = -65 dBm + 90 dBm SNR (dB) = 25 dBm Therefore, the correct answer is that the SNR is 25 dBm.
