NEW QUESTION 155
In the forwarding table of the switch, a MAC address can correspond to only one outlet at a time

True

False

NEW QUESTION 156
Is the following statement about the multicast address used by 0SPFv3 correct?

RD routers use FF02: :6

The DR router uses FF08::6

All OSPF routers use FF02::5

NEW QUESTION 157
The following statement about the application of BFD is correct?

The one-arm echo function refers to the detection of the connectivity of the forwarding link through the loopback operation of the BFD packet

BFD multi-hop detection means that BFD can detect arbitrary paths between two systems that may span many hops or overlap in some parts

BFD and OSPF linkage is to associate BFD and OSPF, and notify OSPF through BFD’s rapid sensing of link failures, thereby speeding up OSPF Response to changes in network topology

BFD single-hop detection refers to the IP connectivity detection of two direct-connected systems

NEW QUESTION 158
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 159
The following statement about IPSG technology is correct (single choice).

The ip source checkuser-bind check-item command is used to configure VLAN- or interface-based IP packet checks, which take effect for both dynamic and static table entries.

If an interface is configured as the OKCP Scooing Tust interface, the interface can normally receive DHCP ACK and DHCPNAK responded to by the OHHNP server and DHCPOffer packets, other untrusted ports cannot receive these packets properly.

On Huawei routers, ipSG functions can be configured in Vlanif.

The IPSG can perform binding table match checks on IP packets entering and leaving the interface.

NEW QUESTION 160
There is a new HW office that needs to use their router as a DHCP server.
When configuring the DHCP server to provide DHCP services to the current office, what of the following items need to be configured?

Exclude unused IP addresses from the DHCP server

Configure the timeout period for ping packets

Configure the startup file for the DHCP server

Configure manual binding

Configure dhcp address pool

NEW QUESTION 161
In SSM, what version of IGMP is required?

IGMPV3

IGMPV4

IGMPV2

IGMPV1

NEW QUESTION 162
Regarding BGP’s recognized arbitrary attributes, which of the following descriptions is correct?

must be passed between BGP neighbors

All BGP routers must be recognized

There is no requirement to be present in the Update message, and you can decide whether to add it to the Update message on a case-by-case basis

The BGP router cannot recognize the

NEW QUESTION 163
If you want to advertise 19072270/27 to an EBGP neighbor, is the following command correct?

network 19072270 mask 255255255224

network 1907227000031

network 19072270255255255224

network 19072270

network 19072270255255255240

NEW QUESTION 164
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 165
The following statement about IPSec VPN is correct? qo

Two routers establish an IPSec VPN in brutal mode, so that the two devices can interact with a minimum of 4 messages to establish a tunnel.

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

The two routers can establish OSPF neighbor relations and exchange intranet routes through the IPSec VPN tunnel

The two routers establish IPSecVPN in main mode, and from the 5th packet (included), the payload’s data will be encrypted.

NEW QUESTION 166
The following link-LSA for OSPFv3 is correct?

Contains both the link-local address of this interface and all IPV6 prefixes of the same area on this router.

Contains both the link-local address of the interface and all IPv6 prefixes on the interface.

?Link-LSA???Prefix?Prefixoptions???Ox00,?? Prefix????IPv6??????

The Option field exists in the header of the LSA, not in the data area of the Link-LSA

NEW QUESTION 167
The firewall has created some security zones by default, which of the following security zones does not exist by default on the firewall? (Radio).

Internet

Local

Trust

DMZ

NEW QUESTION 168
Regarding the domain-authentication-mode md5 hello command in the ISIS process, the correct explanation is?

ISIS authentication cannot be applied in IPv6 environments.

This command is mainly used to make is the ISIS Hello message carry authentication information during the transmission process.

All router domain authentication methods of the same routing domain are MD5, the password is hello, and lS-IS SNP and LSP will spread normally.

outing domain authentication is primarily used to allow level-1 and Level-2 SNP and LSP messages to carry authentication information during delivery.

NEW QUESTION 169
The Next Header field information exists only in the header of an IPv6 message and is used to indicate whether an extended header exists for IPv6

True

False

NEW QUESTION 170
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 171
If you run PIM-SM in a multicast network, you need to build a multicast forwarding tree between the multicast source and the receiver to enable the receiver to receive the multicast effect, so what are the following options for the correct tree sketch for the build?

What is built between the multicast source and the RP is the SPT tree

RP and the receiver is built between the RPT tree

Built between the RPT tree

RP and the swap is the SPT tree

NEW QUESTION 172
Which of the following are single-packet attacks?

Special control message attacks

Scan Probe Attack

DDos Attack

Malformed Message Attack

NEW QUESTION 173
OSPFV is the GP running on the P4 network) OSPF3 is the KGP running on the IP6 network. OsPFV works the same basic way as OSPF2, such as elections for DR and BDR. As shown in the figure, an engineer uses three routers for IP6 service testing, and he wants to interconnect the IPv6 network by running OSPFv3.
Which of the following statements is correct regarding the election of the network DR?

After the network converges, R1 is DR

After the network converges, the engineer modifies the priority of R1 to 100, the priority of R2 to 10, and R3 to the default value. When the network converges again, Rl is DR and R2 is BDR

After the network converges, the broadcast link adds a device, R4, with a priority of 150 When the network converges again, R4 is DR

After the network converges, R1 is powered off and restarted, and when the network converges again, R3 is DR

NEW QUESTION 174
