During STP calculation, the port cost is associated with the port bandwidth by default. Which of the following statements about the relationship between port cost and port bandwidth is true?
In the Spanning Tree Protocol (STP) calculation, port cost is inversely related to port bandwidth. This means that as the bandwidth of a port increases, the associated port cost decreases. Higher bandwidth ports are more efficient and desirable for network paths, hence they are assigned lower costs to prioritize them in the path selection process.
If Proto of a route displayed in the routing table is OSPF, the preference of the route must be 10.
The statement is false. While the default preference for OSPF routes on certain devices, such as Huawei routers, is typically set to 10, this value is not fixed and can be changed by the network administrator. Therefore, the preference of the route does not have to be 10; it must not be assumed to be a constant value.
Which of the following protocols is not a file transfer protocol?
FTP (File Transfer Protocol), TFTP (Trivial File Transfer Protocol), and SFTP (Secure File Transfer Protocol) are all protocols specifically designed for transferring files over a network. HTTP (HyperText Transfer Protocol), while used extensively for transferring web pages and data over the internet, is not primarily a file transfer protocol. Therefore, HTTP packet is not considered a file transfer protocol.
When a switch port receives a frame that does not carry a VLAN tag, it must add a PVID to the frame.
When a switch port receives a frame without a VLAN tag, the switch adds a VLAN tag to the frame with the value corresponding to the Port VLAN ID (PVID). The PVID is an attribute associated with the port itself, not with the frame. Therefore, the correct interpretation of the question is that the switch adds a VLAN tag (which carries the PVID value) to the frame, not that it adds a PVID directly to the frame. Hence, the answer is false.
Which of the following advantages is/are inter-VLAN route interworking in one-arm routing mode?
One-arm routing, also known as router-on-a-stick, reduces the number of physical links required for inter-VLAN routing by utilizing a single physical or logical connection between the router and the switch. This single connection carries multiple VLANs' traffic, thus eliminating the need for multiple links, which is a significant advantage in network configuration.
