NO.33 Which of the following descriptions about VRRP load sharing is correct?

When configuring priorities, make sure that the same router is the master in the RRP backup group

Multiple VRRP backup groups can be created on an interface of a router. The router can be used as both the master of a VRRP backup group and the backup of other VRRP backup groups

When deploying load balancing, the hosts on the same local area network are required to be configured with the IP addresses of different virtual routers as the default gateway addresses.

VRRPLoad balancing requires at least two virtual routers to provide forwarding services at the same time

NO.34 OSPFv2 is running over IPv4 Network IGP: OSPFv3 is running over IPv6 Network IGP: OSP the packet types of Fv3 and OSPFv2 are the same, incl. He11o message, DD message, LSR message, LSU message and LSAck packets. Which of the following statements is true about 0SPFv3 packets?

OSPFv3 ofHello The packet carries the IPv4 address of the router interface6 Address prefix list

OSPFv3 uses the authentication field in the packet header to complete packet authentication

OSPFv3 uses the link-local address as the source address of the sent packet, and the packet can be forwarded outside the range of the originating link

OSPFv3 Use IPv46 multicast addressFF02: :5 andFF02: :6 send OSPFv3 message

NO.35 When the ACL in the RP has multiple matching rules (rules) , which of the following statements is true about the matching order? ( confirmed)

By default, matching is performed according to the “depth first” principle.

By default, match pe first rmit, then match the order of deny.

By default, according to Rule-ID, matching from small to large.

The transmission node device will replace the existing stack top label (outermost label) with the label allocated by the next hop device.

When IP Packet enters MPLS domain, check the destination IP Tunne corresponding to the addressl ID Is the value 0x0 if Tunnel ID value is 0x0, then enter MPLS forwarding process.

when IP Packet enters MPLS domain, MPLS The boundary device is in the packet layer 2 header and IP Insert a new label between the headers sign.

By default, PHP is supported Egress The label value assigned by the node to the penultimate hop node is
3.

data link layer header

upper layer data

network layer header

path record

network layer tail

NO.41 As shown in the figure, all routers run ospf, which of the following statements is correct? (single choice)

R2 willR1 GeneratedRouter LSA forward toR3

R2 in the area 1 and area 0 will generateRouter LSA

R2 willR3 GeneratedRouter LSA forward toR1

R2 only in area 0 generated inRouter LSA

NO.42 aboutRoute Policy, the following description is correct? (multiple choice)

Advanced ACL can be applied to route In policy, filter routes

entry pemit :: 0 less-equal 128 means allow all IPv6 routes to pass through

ifMore than one node is defined in Route-policy, and at least one of each node should have a matching mode of permit

Route-Policy can filter only default routes

NO.43 In a broadcast network, the process starts after the neighbor relationship is established.DIS elections.

True

false

NO.44 The description about configuring BGP4+ is correct: (Not sure)

BGP4+ does not support route reflectors.

The next hop of a BGP4 route can use Link-Local address.

BGP4When configuring the reflector, the roles of the reflector and the client must be the same as the BCP4 configuration.

BGP4 specifies peer must use Link-Local address.

BGP4+ ofThe Router-ID is the same as the Router-ID of BGP4.

NO.45 There is a network consisting of router R1, router R2, router R3 and router R4. The 4 routers are interconnected through a LAN network. All 4 routers have basic oSPF deployed. When you execute the command “display ospf peer” on the router R2, find the router R2 and the route

device the state between R3 is “2-way”. So what can you conclude from this output?
Router R2 is not a DR

Router R3 is not a DR, nor a BDR

router there is no full adjacency between R2 and router R3
routerR4 is DR

Router R2 is DR or BDR
