The correct statement about the difference between OSPFv2 and OSPFv3 is? Multi-select

BOTH OSPFv2 and OSPFv3 support interface authentication. And OSPFv3 authentication is still based on the fields in the ospf message header

OSPFv3 is similar to OSPFv2 in that it uses a multicast address as the OSPF message destination address

The same type of message exists in OSPFv2, OSPFv3: Hello, DD, LSR, LSU, LSAack,. Their message format is the same

OSPFv2 has the protocol number 89 in the IPv4 packet header, OSPFv 3. The next number in the IPv6 message header is 89

NEW QUESTION 96
Regarding the BGP ring protection mechanism, the following description is correct?

A AS_PATH attribute is used between autonomous systems to prevent ring cats.

The Cluster List property is used for reflector cluster inner ring defense, and the router finds that the Cluster List of route entries contains its own Client lD. The route is rejected

Routes learned from IBGP are not advertised to IBGP neighbors and are used to prevent routing loops inside the AS

You can use the AS_CONFED_SET attribute to prevent loops within a consortium

NEW QUESTION 100
When you deploy LLQ, you need to configure bandwidth parameters, what is the significance of bandwidth parameters? (Single choice questions).

Provides a built-in policer to limit the maximum available bandwidth of a low-latency queue during congestion

The parameter should be as small as possible. It means that the bandwidth is always preserved, and even if the LLQ is set, changing the parameters will reduce the available bandwidth of the interface

It represents a reference CIR to calculate the burst size D of the built-in tactician token bucket Changing parameters is an option because LLQ always takes precedence over other queues

NEW QUESTION 101
View the details of all VPN instances on a network device and the results are as follows, which of the following statements is wrong? (Multiple choice questions).

The total number of instances that enable the IPv6 address family in the VPN configured on this side is 1.

VPN-Instance vpna does not receive VPN routes with an RT of 2:1.

The GigabitEthernet 1/0/0 interface is tied to the VPN-Instance vpna

The device assigns a label to each route of the VPN-Instance vpna.

NEW QUESTION 102
?? Route? Policy??:ip community-filter Ipermit 100: 1 ip as-path-filter 2 permit ^I00$ route-policy test permit node 10 if-match communityfilter 1 if-match as-path-filter 2 apply as-path 200 Is the above configuration description correct?

The BGP route matches the above only if the BGP route carries a community attribute value of 100:1 or if the AS PATH is 100 route one policy. The AS-one PATH attribute that matches the route is changed to 200

The BGP route matches the above only if the BGP route carries a community attribute value of 100:1 and the AS-One PATH is 100 route policy?. The AS-PATH nature of the matching route is changed to 200

Only if the BGP route carries an AS-PATH of 100, the BGP route matches the route one policy above. The AS-one PATH attribute that matches the route is changed to 200

As long as the BGP route carries a community attribute value of 100:1, the BGP route matches the route-policy above. The AS-PATH attribute of the matching route is changed to 200

NEW QUESTION 103
The Serial Number field of LS is used to detect expired and duplicate LSAs. The field is a 32bt signed integer, so the small serial number is Ox8000000

True

False

NEW QUESTION 104
The following is an error in the OSPF routing calculation (single choice).

Compared to the PRC algorithm, the ISPF algorithm only calculates the changed leaf nodes when the route changes PRC algorithm to recalculate routes

When the first and second class LSAs on the network change, OSPF uses the ISPF algorithm to recalculate the routes. The

OSPF router uses the FULL SPF algorithm to calculate all nodes in the network when initially calculating routes

NEW QUESTION 105
Is the following statement about VLAN aggregation correct?

Sub-VLAN is used to isolate broadcast domains

A Super VLAN can contain one or more Sub-VLANs

The super Sub-VLAN contains a physical interface that can establish a Layer 3 VLANIF interface

Sub-VLAN contains a physical interface that can establish a Layer 3 VLANIF interface

NEW QUESTION 106
CMPv6 uses the Type field to identify the message type, and according to the value of the type field, we can divide the ICMPv6 message into two categories, one is the error message and the other is the information message

True

False

NEW QUESTION 107
After you divide an interface of the firewall into the Untrust security domain, the interface belongs to the Untrust zone and no longer belongs to the Local zone.

TRUE

FALSE

NEW QUESTION 108
Regarding IPv6 over IP4(19) road, the following statement is correct

The 6to4 automatic tunnel requires the use of a specific IP6 address segment, and the assigned address segment is preceded by 3ffe::/16

When configuring manual tunneling on the VRP platform, a Tunnel interface is generally created; When configuring automatic tunneling, a Vrua-Template interface is usually created

The ISATAP tunnel determines the destination IPV4 address of the tunnel based on the destination IP6 address.

All automatic tunnels encapsulate data in the same way.

Automatic tunneling has great advantages over manual tunneling, and manual tunneling will be phased out

NEW QUESTION 113
The following description of BGP load sharing is wrong with? (Multiple choice question)

The AS_Path properties of the equivalent routes that form load sharing must be different.

The destination CIDR blocks are the same, and load sharing can be formed between BGP routes with different sources.

If BGP load sharing is implemented, the local device needs to configure the peer next-hop-local command to change the next hop address to its own address when issuing a route to an IBGP peer group.

IBGP routes and EBGP routes that reach the same destination in the public network can form a load sharing
