Which well-known port is used to access the Cisco IP Video Surveillance Operations Manager via a secure, ActiveX web session?
The correct answer is E. 443. Port 443 is the IANA-assigned well-known port for HTTPS, which provides the TLS encryption required for a secure ActiveX web management session.

Why each option
Port 443 is the IANA-assigned well-known port for HTTPS, which provides the TLS encryption required for a secure ActiveX web management session.
Port 20 is reserved for FTP data transfer and is unrelated to web-based management sessions.
Port 80 is plain HTTP and does not provide the encryption required for a secure web session.
Port 421 is not an IANA well-known port assigned to HTTPS or any Cisco VSM management function.
Port 434 is not a well-known port associated with secure web access to Cisco IP Video Surveillance components.
Port 443 is the standard HTTPS port defined in RFC 2818, providing TLS-encrypted HTTP transport. The Cisco IP Video Surveillance Operations Manager uses HTTPS on port 443 for its secure web-based management interface, including ActiveX-based sessions. Any browser or ActiveX control connecting to the appliance for administration uses this port to establish an encrypted channel.
Port 8080 is a common alternate HTTP port used for non-secure web proxies or secondary web services, not for encrypted HTTPS sessions.
