This statement is FALSE . In Huawei firewall hot standby networking, the heartbeat link is used for important communication between the two devices, such as peer status detection, role negotiation, and hot standby related information exchange. However, the heartbeat interfaces do not have to be directly connected with a cable in all cases.

The two heartbeat interfaces can be connected through an intermediate Layer 2 switch , as long as the link is reliable and can properly carry heartbeat traffic between the two firewalls. What matters most is that the heartbeat communication remains stable, low-delay, and uninterrupted, because failure of the heartbeat link may affect peer monitoring and could trigger unnecessary active/standby switching.

In many practical deployments, direct connection is preferred because it is simpler and can reduce the risk of intermediate device failure. Even so, “preferred” is not the same as “must.” The requirement is for a dependable heartbeat path, not strictly a point-to-point cable connection between the two firewalls.

Therefore, the statement saying the heartbeat interfaces must be directly connected is incorrect, so the correct answer is FALSE .

The incorrect statements are A and C .

A router works at the network layer and is used to connect different networks. By default, a router separates broadcast domains , because broadcasts are not forwarded from one interface to another. At the same time, each router interface also represents an independent network segment, so routers effectively separate collision domains as well. Therefore, the statement that routers can isolate broadcast domains but not collision domains is incorrect.

A Layer 2 switch works at the data link layer. Each switch port forms a separate collision domain , which is why switches can isolate collision domains. However, by default, all ports in the same VLAN still belong to the same broadcast domain , so switches forward broadcast traffic out all relevant ports. That makes statement B correct and statement D correct.

Statement C is incorrect because routers generally do not forward broadcast packets . Preventing broadcast propagation between networks is one of the key differences between routers and switches. Therefore, the incorrect options are A and C .
