B.Prefix lists can be used to filter both routes and packets.

C.When filtering routes using the pre-slow list, the table entry ip-prefxldeny0000 0 lese-qual 32 indicates that only the default route matches

D.With Filter-Policy, on ASBR in OSPF, type5LSA and type7LSA can be applied The build is filtered.

Question 32

D.R2 can learn the 101.20/24 and 101.30/24 routes.

Question 33

OSPF fast convergence is an extended feature to improve the convergence speed of routing, in which PRC works by speeding up routing computation by performing path calculations only on the affected nodes when the network topology changes.

Question 34

Regarding the cross-domain VPN-OptionB scenario, what is the following description incorrect?

A.Cross-domain VPN An Option

B.scheme is not limited by the number of interconnection links between ASBRs

D.The outer layer label is exchanged between two ASBRs to VPNv4 routes.

Question 35

In the description of the MAC address spoofing attack, the error is ? Radio

A.Mac address spoofing attacks cause the switch to learn the wrong mapping of Mac addresses to IP addresses

B.An attacker can perform a MAC address spoofing attack by sending a forged source Mac address data frame to the switch

C.A MAC address spoofing attack causes the data that the switch is sending to the correct destination to be sent to the attacker

D.MAC address spoofing attacks primarily exploit the switch Mac address learning mechanism
