Which two options are potential problems with route aggregation? (Choose two)

Maintaining host IP addresses during migrations is a DHCP or IP management concern, not a consequence of route aggregation.

Route flapping is caused by unstable links or BGP instability, not by the act of summarizing routes.

When a summary route is advertised, remote routers lose visibility into the specific prefixes behind it, potentially selecting a longer or less efficient path to reach a destination - this is suboptimal routing caused by information loss.

Topology hiding is a known side effect of aggregation but is often an intentional design choice for scalability, not a problem in the same operational sense as suboptimal or asymmetric routing.

Asymmetric routing results when inbound and outbound traffic follow different paths: a remote router uses the aggregate to reach a destination via one exit point while the return traffic follows a more specific route back through a different exit point.

Prefix hijacking is a BGP security threat caused by unauthorized route announcements, not a structural result of route aggregation.
