Explanation
SW3 does not have VLAN 60 so it should not receive traffic for this VLAN (sent from SW2).
Therefore we should configure VTP Pruning on SW3 so that SW2 does not forward VLAN 60 traffic to SW3. Also notice that we need to configure pruning on SW1 (the VTP Server), not SW2.

Explanation
"The next step is to configure the WLC for the Internal web authentication. Internal web authentication is the defaultweb authentication type on WLCs." In step 4 of the link above, we will configure Security as described in this question. Therefore we can deduce thisconfiguration is for Internal web authentication.

Explanation
Once you know the complete combination of transmitter power level, the length of cable, and the antenna gain, you can figure out the actual power level that will beradiated from the antenna. This is known as the effective isotropic radiated power (EIRP), measured in dBm.
EIRP is a very important parameter because it is regulated by governmental agencies in most countries. In those cases, a system cannot radiate signals higher than a maximum allowable EIRP. To find the EIRP of a system, simply add the transmitter power level to the antenna gain and subtract the cable loss.
Suppose a transmitter is configured for a power level of 10 dBm (10 mW). A cable with 5-dB loss connects the transmitter to an antenna with an 8-dBi gain. The resultingEIRP of the system is 10 dBm - 5 dB + 8 dBi, or 13 dBm.
You might notice that the EIRP is made up of decibel-milliwatt (dBm), dB relative to an isotropic antenna (dBi), and decibel (dB) values. Even though the units appear tobe different, you can safely combine them because they are all in the dB "domain".

Explanation
Encapsulated remote SPAN (ERSPAN): encapsulated Remote SPAN (ERSPAN), as the name says, brings generic routing encapsulation (GRE) for all captured traffic and allows it to be extended across Layer 3 domains.
