In different scenarios, RSTP provides different protection functions, and the wrong statement about this statement is

  1. The root protection feature is enabled for the specified port, and its port role can only remain as the specified port
  2. When the anti-TC-BPDU packet attack feature is enabled, the number of times the switching device processes IC BPDU packets per unit time is configurable
  3. after the BPDU protection function is enabled on the switching device, if the edge port receives RST BPDU, the edge port will be set to a non-remote port and the spanning tree calculation will be re-performed
  4. Start the specified port of root protection, when the port receives a better RSTBPDU, the port will enter the Discarding state and is no longer forwarding packets. If the port does not receive a better RSTBPD for a period of time then automatically revert to the normal Forwarding state

q252: dns poisoning is the correct answer, not locator redirection. beaconing is detected from a host. this indicates that the system has been infected with malware, which could be the source of local dns poisoning. location redirection works by either embedding the redirection in the original websites code or having a user click on a url that has an embedded redirect. since users at a different office are not getting redirected, it isnt an embedded redirection on the original website and since the user is manually typing in the url and not clicking a link, it isnt a modified link.
