Question 21

When planning IPv4 addresses for a campus network, which of the following methods can you use to assign an IP address to the interface connecting the campus egress device to the WAN? (Choose all that apply.)

1. Using DHCP to dynamically assign an IP address
2. Using PPPoE to obtain an IP address
3. Manually configuring a static IP address
4. Using SLAAC to automatically obtain an IP address

Question 22

Enabling STP and configuring the core device as the root bridge is recommended, even if no physical loop exists on the switched network. This prevents Layer 2 loops caused by incorrect connections between devices and avoids network reconvergence caused by root bridge preemption.

1. TRUE
2. FALSE

Question 23

On the campus network shown in the figure below, the core switch Core1 functions as a Layer 3 gateway and as a DHCP server to dynamically assign IP addresses to AP1, PC1, PC2, and PC3. The network below Core1 is a Layer 2 network. WAC1 and R1 are connected to Core1 at Layer 3. AP1 goes online through VLAN 100. VLAN 101 and VLAN 102 are respectively used for the wireless and wired services. Additionally, the tunnel forwarding mode is used for wireless traffic forwarding. Match device interfaces with their respective allowed VLANs. (Note: No additional VLANs are allowed on device interfaces, and interconnection VLANs are not considered.)

Question 24

There are several distinct topologies for data communication networks.Which of the following network topologies presents the risk of network-wide communication breakdown in the case of a single device fault?

1. Ring topology
2. Star topology
3. Mesh topology
4. Tree topology

Question 25

Huawei network devices support multiple types of storage devices. After the administrator enters the save command in the user view of a switch, the current configuration file is saved to the SDRAM. After the switch restarts, the configuration file still takes effect.

1. TRUE
2. FALSE
