Explanation
a) A device with IP address 10.1.3.7 in a network wants to send the traffic stream to a device with IP address
10.13.4.2 in the other network -> Unicast
b) One/more senders and one/more recipients participate in data transfer traffic -> Multicast c) Sent to all hosts on a remote network -> IP Directed Broadcast d) Sent to all NICs on the same network segment as the source NIC -> Broadcast References: 1 https://www.thestudygenius.com/unicast-broadcast-multicast/ The terms broadcast, IP directed broadcast, multicast, and unicast are different types of communication or data transmission over a network. They differ in how many devices are involved in the communication and how they address the messages. The following table summarizes the characteristics of each term1:

Explanation
This is the correct definition of BSS coloring and its primary benefit. BSS coloring is a mechanism that assigns a color code to each BSS (Basic Service Set), which consists of an AP and its associated clients. The color code is added to the PHY header of each frame transmitted by the AP or the client. BSS coloring helps reduce co-channel interference by allowing devices to differentiate between frames from their own BSS and frames from neighboring BSSs that use the same channel. Devices can then adjust their threshold for interference based on the color code and decide whether to transmit or defer based on the channel status. The other options are incorrect because they either describe different mechanisms or benefits of BSS coloring or use incorrect terms. References:

Explanation
This is the correct action to fix the issue where the SSID is not working as expected. WPA3-Enhanced Open is a new security standard for public networks that uses Opportunistic Wireless Encryption (OWE) to provide encryption and privacy on open, non-password-protected networks. WPA3-Enhanced Open can be configured on an Aruba Access Point by changing the SSID security mode to WPA3-Enhanced Open in Aruba Central or Aruba Instant. The other options are incorrect because they either do not use WPA3-Enhanced Open or do not exist as valid security modes. References:

Explanation
Option A shows the correct commands to ensure that no rogue DHCP server will impact the network. The commands include the following steps:
* Enable DHCP snooping on the switch. DHCP snooping is a feature that prevents rogue DHCP servers from offering IP addresses to clients by filtering DHCP messages based on trusted and untrusted ports1.
* Configure VLANs 100, 110, and 120 as DHCP snooping VLANs. This means that DHCP snooping will be applied to these VLANs and any untrusted DHCP messages received on these VLANs will be dropped1.
* Configure LAG 1 as a trusted port for DHCP snooping. This means that any DHCP messages received on LAG 1 will be allowed and not filtered by DHCP snooping. LAG 1 is assumed to be connected to a legitimate DHCP server or a router that relays DHCP requests to a legitimate DHCP server1.
Option B is incorrect because it does not enable DHCP snooping on the switch or configure VLANs 100, 110, and 120 as DHCP snooping VLANs. Option C is incorrect because it does not configure LAG 1 as a trusted port for DHCP snooping. Option D is incorrect because it does not enable DHCP snooping on the switch or configure LAG 1 as a trusted port for DHCP snooping. References: 1

Explanation
To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF. References:
