The output is most likely an example of an ARP poisoning attack. ARP poisoning, also known as ARP spoofing, is a type of attack that exploits the ARP protocol to associate a malicious device's MAC address with a legitimate IP address on a local area network. This allows the attacker to intercept, modify, or redirect network traffic between two devices without their knowledge. The output shows that there are multiple entries for the same IP address (192.168.1.1) with different MAC addresses in the ARP cache of the device. This indicates that an attacker has sent fake ARP replies to trick the device into believing that its MAC address is associated with the IP address of another device (such as the default gateway).

Biometrics is a type of authentication that uses a person's physical characteristics, such as fingerprints, iris, or face, to verify their identity. An access control vestibule is a small room or area that separates two spaces and allows only one person to enter or exit at a time. Biometrics in an access control vestibule is the most effective physical security method to prevent tailgating, which is the unauthorized entry of a person behind another person who has legitimate access.

Routing is the process of forwarding packets from one network to another, based on the destination IP address1.
Routing occurs at the network layer of the OSI model, which is the third layer from the bottom2.
The network layer is responsible for logical addressing, path selection, and packet delivery across multiple networks2.
Routers are the devices that operate at the network layer and perform routing functions, using protocols such as RIP, OSPF, EIGRP, or BGP23.
The other layers of the OSI model have different roles in the network communication process, such as:
The data link layer is the second layer from the bottom, and it is responsible for framing, addressing, and error detection of data packets over a single network, using protocols such as Ethernet, Wi-Fi, or PPP2.
The transport layer is the fourth layer from the bottom, and it is responsible for ensuring reliable, error-free, and ordered data transfer between devices, using protocols such as TCP or UDP2.
The physical layer is the bottom layer, and it is responsible for transmitting and receiving bits over a physical medium, such as a cable, a fiber, or a wireless signal2. Reference:

SSID (Service Set Identifier) is a feature that should be configured to allow different wireless access through the same equipment. SSID is the name of a wireless network that identifies it from other networks in the same area. A wireless access point (AP) can support multiple SSIDs with different security settings and network policies. For example, a store owner can create one SSID for business equipment and another SSID for patron use, and assign different passwords, VLANs, and QoS levels for each SSID.

The problem is likely related to DNS resolution, as the clients are able to ping the server's IP address but not access the web resource via URL. The other answers do not address this issue. Configuring A records for the web server will ensure that clients are able to access the web resource via its domain name.
