You have attempted to configure DHCP snooping, but it is not working as expected. Based on the output below, what do you need to configure?

DHCP snooping requires to be enabled globally before it will function correctly. If it is not enabled globally, even if enabled on VLAN interfaces, DHCP snooping will not work.
Enabling authorized DHCP servers (A) or trusted interfaces (B) is necessary but only after global enabling.
Enabling DHCP snooping on VLAN (C) is not sufficient without global enablement.
Therefore, enabling DHCP snooping globally is the first step to activate the feature.

An ACME company employee complained about a recent poor-quality VoIP call while moving around their office environment. HPE Aruba Networking Central reported a fair UCC score for this call while your VoIP engineer reported that their systems reported a MOS of 2.3. The VoIP devices are operating over the 5GHz frequency band.

You are planning a 1 Gbps link between two CX switches. Which type of SFP port will be required?
For a 1 Gbps link between two Aruba CX switches, the appropriate SFP port type is an SFP (Small Form-factor Pluggable). SFP+ and SFP28 are used for higher speeds such as 10 Gbps and 25 Gbps, respectively. QSFP+ is for even higher speeds (40 Gbps).
SFP supports 1 Gbps (1000BASE-X)
SFP+ supports 10 Gbps
SFP28 supports 25 Gbps and above
QSFP+ supports 40 Gbps and above
Therefore, the correct port type for a 1 Gbps link is SFP.

Refer to the exhibit:

The customer would like to utilize Dynamic Segmentation for wired users in Building B. Which statement is true about the scenario?
Dynamic Segmentation (DS) requires certain capabilities on the switches to support user role assignment and traffic segmentation based on identity. The CX 6100 series switches do not support Dynamic Segmentation due to hardware and feature limitations. Therefore, they must be replaced with CX 6300 models, which support DS features natively.
Options involving GRE tunnels or VXLAN tunnels relate to traffic forwarding but do not enable DS on unsupported hardware.
Applying licenses does not upgrade hardware capabilities for DS.
