Is the following description of the OSPFv3 message correct?

Question 411

The following description of Filter-Policy is correct?( Radio).

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

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

Filter-policy filters the link state information received or published, and can modify the properties of route entries.

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

Question 412

Deploying the ISIS protocol in an IPv6 environment is true in the following statement (radio).

By default, the DIS priority of broadcast network interfaces at Level-1 and Level-2 is 1

In broadcast networks, the DIS priority for IPV4 and IPV6 can be set separately

In the same broadcast network. If each router supports both IPV4 and Pv6, the DISC of JPV4 and Pv6 must be the same device

IS-IS sient is configured under the finger port, this interface will not send ISIS packets, but will receive ISIS packet

Question 415

The following statement about IPSec VPN is correct

Brutal mode can support NAT traversal, while main mode does not support NAT traversal.

The two routers establish IPSecVPN in main mode, and from the 5th message (included), the payload's data is often encrypted.

Two routers establish an IPSec VPN in brutal mode, so that the tunnel is built with a minimum of 4 messages interacting between the two devices.

The two routers can establish an OSPF neighbor relationship through the IPSec VPN (19) channel and exchange intranet devices by

Question 416

For Layer 2 VPN technology, the following statement is correct? Multi-select

VPLS is a widely used technology in the live network, which can provide transparent transmission of three-layer messages and achieve multi-point access.

The VPLS configuration is complex and the Layer 2 network transmits BUM packets.

BGPEVPN supports features such as tenant isolation, Multi-homing, and broadcast suppression. D.BGPEVPN addresses mac address drift and multi-tenancy that VPLS cannot support.

8021D bridge only forwards BPDU packets received from the root bridge

The 8021D bridge does not forward BPDU messages

The 8021w bridge forwards only BPDU packets received from the root bridge

8021w Bridge does not forward BPDU packet

Question 418

In a network, the same gigabit running S and OSPF anti-tampering and fluttering as shown in the figure, on the two border routers RTB and RTC are introduced into the wine route, the device question is to use gigabit one port strobe, , 222 The network is introduced into the OSE via impotrote direct on the RTD, assuming that all other configurations are dead default configurations, then the description of this network is wrong ?

Adjusting the ISIS priority to 160 on the RTB avoids suboptimal routing problems in the network.

On the RTC, the following configuration is adopted, only the routes of the 2222/32 cinder segment can be filtered out when routing is introduced, IRTClip ip-prefix 10 index 1 deny2000 8 lessequal 32

RTB learns that the routing next hop for the 2222/32 network segment is RTA

The following configuration can filter out the routes of the 2222/32 CIDR block of the white RTD when RTC introduces OSPF routes.
