Detailed Explanation:To manage a router in a remote branch office, Telnet is a suitable option as it allows remote access over a network. Unlike a console connection, which requires physical access, Telnet enables remote management as long as the administrator has network connectivity to the router. FTP is used for file transfer, and DHCP is used for dynamic IP address allocation, not for management​​.

A (Correct): Stacking allows inter-chassis Ethernet Trunks to be created, improving redundancy and bandwidth.

B (Correct): Multiple switches act as a single logical device, simplifying network management.

C (Correct): Stacking increases available ports, allowing expansion without adding separate devices.

D (Correct): By enabling redundancy, stacking and CSS help prevent single points of failure in the network.

Thus, the correct answers are A, B, C, and D.

To form an EUI-64 address, the MAC address is split and FFFE is inserted in the middle, making the EUI-64 format 00E0-FCEF-FFFE-0FEC. Additionally, the 7th bit of the first byte is flipped to form the Modified EUI-64 address used in IPv6 for Stateless Address Autoconfiguration (SLAAC)​.

Comprehensive Explanation: In STP (Spanning Tree Protocol), ports can be in several states, including:

Discarding: The port is not forwarding traffic, either because it is in a blocking state or not participating in active forwarding.

Listening: The port is processing BPDUs and is preparing to transition to either the learning or forwarding state. No data frames are forwarded during this state.

Forwarding: The port is actively forwarding traffic as part of the active network topology.

The "Disabled" state is not part of the STP protocol but rather represents a port that is administratively shut down or not participating in the STP process.
