Which feature can you implement to reserve bandwidth for VoIP calls across the call path?
Which feature can you implement to reserve bandwidth for VoIP calls across the call path?
To reserve bandwidth for VoIP calls across the call path, the feature that can be implemented is RSVP (Resource Reservation Protocol). RSVP is designed specifically for reserving resources across a network, ensuring that certain applications, like VoIP, have the required bandwidth to maintain quality of service.
Which three statements about link-state routing are true? (Choose three.)
Link-state routing is a method that requires routers to have more knowledge about the internetwork. OSPF is a widely known link-state protocol. Link-state routing routes are updated when there's a change in topology, which allows for dynamic responses to network changes. By default, updates in link-state routing protocols like OSPF are sent to a multicast address instead of a broadcast address.
Which command can you enter to determine whether a switch is operating in trunking mode?
To determine whether a switch is operating in trunking mode, you would use the 'show interface switchport' command. This command provides detailed information about the switchport, including whether it is in access mode or trunk mode. The other commands do not provide specific information about trunking status.
What are three benefits of implementing VLANs? (Choose three.)
Implementing VLANs provides several benefits. First, a higher level of network security can be reached by separating sensitive data traffic from other network traffic (option A). This separation ensures that sensitive information is only accessible within specific VLANs, enhancing security. Second, a more efficient use of bandwidth can be achieved by allowing many logical networks to use the same network infrastructure (option C). By segmenting networks logically rather than physically, VLANs optimize the utilization of available bandwidth. Lastly, broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size (option G). This reduces the overall impact of broadcast traffic on the network, enhancing performance and reliability.
Which command can you enter to view the ports that are assigned to VLAN 20?
The command 'Switch#show vlan id 20' allows you to view the VLAN information, including the ports assigned to VLAN 20. This command displays detailed information about the VLAN, such as the VLAN name, status, and the interfaces that are part of it. The other commands do not provide a direct mapping of ports to a specific VLAN.
