 During the discovery phase of a WLAN setup, the DHCP server works in conjunction with Option 43 to provide at least one management interface IP address to an AP. This process is dependent on the Vendor Class Identifier (VCI) of the AP. The VCI is a unique identifier that enables the DHCP server to recognize the type of device requesting an IP address and provide appropriate configuration information specific to that device. In this case, Option 43 is used to return management interface IP addresses that are specific to the WLAN APs.

Suppose a transmitter is configured for a power level of 10 dBm. A cable with 5-dB loss connects the transmitter to an antenna with an 8-dBi gain. The resulting EIRP of the system is EIRP = 10 dBm – 5 dB + 8 dBi = 13 dBm.

The mechanism that ensures non-disruptive operation during the active supervisor module removal in a Cisco Catalyst switch is Stateful Switchover (SSO). SSO allows the standby supervisor module to take over the operation seamlessly when the active supervisor is removed. This feature maintains the network state and other important information, allowing the switch to continue operating without interruption. References: Cisco Catalyst 9400 Series Supervisor Module Installation Note1.

The correct command set to deny Telnet traffic from the loopback interface of router R3 to the Loopback interface of router R2 during weekend hours while allowing all other traffic at all times is depicted in Option C. This is because the access list in Option C specifies a time-range named WEEKEND that defines the weekend hours from 00:00 on Saturday to 23:59 on Sunday. The access list then denies TCP traffic (which includes Telnet) from host 10.3.3.3 to host 10.2.2.2 eq telnet within this time range, while permitting IP traffic at all other times. References: Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) training materials and study guides provide information on how to configure time-based ACLs which are used in this scenario.
