QUESTION: 28

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)

Option A
Option B
Option C
Option D

Answer(s): C

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 domain.
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.

QUESTION: 29

In an ArubaOS 10 architecture using an AP and a gateway, what happens when a client attempts to join the network and the WLAN is configured with OWE?

Authentication information is not exchanged
The Gateway will not respond.
No encryption is applied.
RADIUS protocol is utilized.

Answer(s): A

Explanation:

This is the correct statement about what happens when a client attempts to join the network and the WLAN is configured with OWE (Opportunistic Wireless Encryption). OWE is a standard that provides encryption for open networks without requiring any authentication or credentials from the client or the network. OWE uses a Diffie-Hellman key exchange mechanism to establish a secure session between the client and the AP without exchanging any authentication information. The other options are incorrect because they either describe scenarios that require authentication or encryption methods that are not used by OWE.

QUESTION: 30

Which Aruba AP mode is sending captured RF data to Aruba Central for waterfall plot?

Hybrid Mode
Air Monitor
Spectrum Monitor
Dual Mode

Answer(s): C

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.

QUESTION: 31

What is a primary benefit of BSS coloring?

BSS color tags improve performance by allowing clients on the same channel to share airtime.
BSS color tags are applied to client devices and can reduce the threshold for interference
BSS color tags are applied to Wi-Fi channels and can reduce the threshold for interference
BSS color tags improve security by identifying rogue APs and removing them from the network.

Answer(s): C

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 channel. Each BSS is assigned a color code, which is a 6-bit value that is carried in the PHY header of the Wi-Fi frames. 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 colors. This can improve the spectral efficiency and throughput of the network. The other options are incorrect because they do not describe the primary benefit of BSS coloring.
