Olimpiade MikroTik - Bridge & Switch

PPOE stands for Point-to-Point Protocol over Ethernet. It is a network protocol that is used to establish a connection between a network access server and a client. PPOE cannot be made into a bridge interface because it is a protocol that operates at the network layer, while a bridge is a device that operates at the data link layer. Therefore, PPOE cannot be used as a bridge interface.

The correct answer is Data Link. A bridge is a feature that connects interfaces into one logical interface. In the context of MikroTik, this feature operates at the Data Link layer. The Data Link layer is responsible for the reliable transmission of data between two directly connected nodes, such as Ethernet frames. Therefore, the bridge feature in MikroTik operates at this layer to connect and manage interfaces effectively.

A bridge is an interface that is created with the purpose of combining multiple Ethernet and wireless connections to use the same network segment. It allows devices connected to different networks to communicate with each other as if they were on the same network. Unlike a router, which connects different networks, a bridge connects devices within the same network segment, making it the correct answer in this context. An Access Point (AP) Bridge is a type of bridge that connects wireless devices to a wired network.

The correct answer is Layer 2. The switchchip feature on a MikroTik routerboard operates at Layer 2 of the OSI model. This means that it is responsible for handling Ethernet frames, including forwarding, filtering, and switching them between connected devices on a local area network. Layer 2 is primarily concerned with the physical addressing of devices and the creation of local networks.

When interface port 3 on the routerboard is set as the switch master port for interface port 1, and this interface is connected to a client, there will be a total of 2 LEDs that will light up. One LED will be on interface port 3 and the other LED will be on interface port 1.

The interface wlan1 on a routerboard cannot be configured into a switch port. This is because wlan1 is a wireless interface, specifically designed for wireless communication, and cannot be used as a regular switch port for wired connections.

The correct answer is RSTP. RSTP stands for Rapid Spanning Tree Protocol, which is a communication protocol used by a bridge interface to prevent data looping. It is an improved version of the Spanning Tree Protocol (STP) and provides faster convergence in case of network changes. TCP and UDP are transport layer protocols used for data transmission over a network, but they are not specifically designed for preventing data looping on a bridge interface.

To configure the priority on an interface in a bridge, you need to set the "Priority" option. This option allows you to assign a priority value to the interface, which determines its priority in the spanning tree protocol (STP) or rapid spanning tree protocol (RSTP) calculations. By setting a higher priority value, you can make the interface more likely to be chosen as the root bridge or designated bridge, thereby influencing the path selection in the network.

The correct answer is "Masquerade." Masquerade is not an option in the configuration of Bridge NAT. Masquerade is a type of NAT that allows a network to share a single IP address for outgoing traffic. It replaces the source IP address of outgoing packets with the IP address of the router, allowing multiple devices on the network to access the internet using a single IP address. In the context of Bridge NAT, Masquerade is not applicable as it is used in other types of NAT configurations.

To configure a switch on a routerboard through winbox, we need to go to the "Switch" menu. This menu allows us to manage and configure the switch settings on the routerboard. Here, we can set up VLANs, enable/disable ports, configure port speeds, and perform other switch-related configurations.

The correct answer is "Rules" because the question asks for the feature that is not present in the switch menu options. The other options, Port, VLAN, and Host, are all commonly found in switch menus and are used to configure different aspects of the switch's functionality. However, "Rules" is not typically listed as a menu option in switch configurations, as it is a term more commonly associated with firewall or routing configurations.

The information that is not displayed in the Bridge > Host menu when multiple clients are connected to an interface within a bridge is the IP Address. This means that the menu will not show the IP addresses of the clients that are connected to the bridge interface.

The correct answer is "Host." The question is asking on which interface we can check the number of hosts connected to an Ethernet interface on a switch. The term "Host" refers to the devices or computers connected to the network, so it is the interface where we can find information about the number of hosts connected.

The correct answer is "Master Port". In order to configure the switchchip feature on a routerboard, we need to define the main interface and specify the interfaces that will be part of the switch. The main interface is determined by configuring the "Master Port" option.

In the given options, we determine the priority of an interface bridge in STP (Spanning Tree Protocol). STP is a network protocol that prevents loops in Ethernet networks by creating a loop-free logical topology. The priority value determines the root bridge in the network, with the lowest priority value being elected as the root bridge. Therefore, setting the priority for an interface bridge in STP helps determine its role in the network topology.

The correct answer is "Ports". In networking, a port is a logical construct that represents a specific process or service on a networked device. When configuring a bridge, we need to specify the ports to add interfaces to the bridge. By adding interfaces to a bridge's ports, we can connect multiple networks or segments together, allowing communication between devices connected to different interfaces. Therefore, the option "Ports" is the correct choice for adding interfaces to a bridge.

To apply filtering rules on the Bridge interface, we need to access the "Filters" menu. This menu allows us to configure and set up the necessary filtering rules for the Bridge interface. By accessing the Filters menu, we can define the specific rules and criteria for filtering network traffic on the Bridge interface.

The correct answer is "Switch Chips". Switch Chips refers to the feature on a routerboard that allows multiple interfaces to function as one segment. This feature enables the routerboard to combine the bandwidth and improve the overall performance of the network. Switch Chips are specialized integrated circuits designed specifically for handling network switching tasks efficiently. They provide high-speed data transfer and facilitate the seamless merging of multiple interfaces into a single segment.
