QUESTION 198
The following information related to MPLS labels is described incorrectly? .

By default, the device supports PHP feature, the Egress node that supports PHP assigns the label value of 3 to the penultimate hop node.

When the value of the label is 0, it means that the label must be popped, and the forwarding of the packet must be based on IPv4.4

MPLSThe tag is 4 bytes long and is encapsulated between the link layer and the network layer.

If the stack bottom label in the label is S=0, it indicates that the label is the stack bottom label, and the IP is directly performed.Forward.

QUESTION 199
when ABWhen R is a type 5/7 LSA conversion router in the NSSA area, the ABR can aggregate the type 5 LSA converted from the type 7 LSA.

True

false

QUESTION 200
In addition to stateless address autoconfiguration, IPV6 devices can alsoDHCPv6 obtains information such as address, gateway, DNS, etc.

True

false

QUESTION 201
Check the LSP on a router and see the following results:

When sending a data packet whose destination address is 4.4.4.4, it is sent directly without tagging.

The sending destination address is 2.2.2 2 data packets are sent directly without tagging.

When sending a packet whose destination address is 3.3.3.3, tag 1026 and send it.

When the router receives a packet with a label of 1024, it will replace the label with 1027 and send it.

QUESTION 202
The MAC address table of the switch with default configuration is empty at this time, and the host A connected to the switch sends the first unicast data frame, then what operation will the switch perform after receiving the instruction?

The switch will drop the frame

The switch will record the source MAC address of the data frame and flood the data frame

The switch will forward the data out an interface according to the destination MAC address of the data frame

The switch will buffer the data frame and forward it after waiting for the destination host to send the data frame

QUESTION 203

DR routers use FF08::6

DR routers use FF02::6

All OSPsF Router uses FFO2::5

All OSPsF Router uses FF08:5

QUESTION 204
Which of the following statements about ISIS protocol routing aggregation is true

Route aggregation can be configured and effective on all types of routers.

Route aggregation can only take effect when configured on level-1 routers

Route aggregation can only be done at level-2 The configuration on the router can take effect

Route aggregation can only be done at level-1-2 The configuration on the router can take effect

QUESTION 205
OSI Reference Model and which layers in the TCP/IP model are common? (multiple choice)

session layer

data link layer

transport layer

presentation layer

physical layer

application layer

QUESTION 206
As shown below, which routes will R2 learn? ( confirmed)

R2 can learn two routes, 10.1.2.0/24 and 10.1.3.0/24.

R2 can learn the route 10.1.1.0/24.

R2 can receive the LSP of R1, but cannot add it to the routing table.

R2 can learn all routes of R1.

QUESTION 207
The BGP protocol is an inter-domain routing protocol. The following description of the protocol is correct:

Supports rich routing strategies

The BGP protocol adopts a reliable transmission protocol

It does not support neighbor authentication

Support automatic discovery of neighbors

QUESTION 208
What is the meaning of the display current-configuration I include vlan command?

View all configurations that contain the keyword “VLAN”

Check the IP address of the VLANIF interface

Check which WLANs are currently created

Check the physical interface information bound under each LAN

QUESTION 209
Which of the following statements about VXLAN packets is correct?

The outer destination IP address is VXLAIP address of the remote VTEP of the N tunnel

The source UDP port number is 4789

PurposeUDP port number is 4789

VNI has 24 bits for distinguishing VLAN segments

Explanation
VXLAN (Virtual eXtensible Local Area Network, virtual extended local area network), is NVO3 (Network Virtualization) defined by IETF over Layer 3) One of the standard technologies, using L2 over L4 (MAC-in-UDP) packet encapsulation mode, which encapsulates Layer 2 packetsEncapsulation with the Layer
3 protocol can realize the expansion of the Layer 2 network within the scope of the Layer 3, and at the same time meet the needs of the large Layer 2 virtual migration and multi-tenancy of the data center.
VTEP (VXLAN Tunnel Endpoints, VXLAN tunnel endpoints): VXLAThe edge device of the N network is the start and end point of the VXLAN tunnel, and the related processing of VXLAN packets is performed on this.
VNI (VXLAN Network Identifier, VXLAN network identifier):
VXLAThe N header and the original Ethernet frame are used as UDP data. In the UDP header, the destination port number (VXLAN Port) is fixed to 4789, the source port number (UDP Src. Port) is the value of the original ether frame calculated by the hash algorithm.
source IP address (Outr Src. IP) is the V to which the source VM belongsThe IP address of the TEP, the destination IP address (Outer Dst. IP) is the V to which the destination VM belongsIP address of the TEP.
Source MAC address (Src. MAC Addr.) is the MAC address of the VTEP to which the source VM belongs, and the destination MAC address (Dst. MAC Addr.) is the MAC address of the next-hop device on the path to the destination VTEP.

QUESTION 210
OSPFv2 is running over IPv4 Network IGP: OSPFv3 is running over IPv6 Network IGP. OSPFv3 and Compared with 0SPFv2, it has similar LSA types, but with slightly different functions. Which of the following is not included in the OSPFv3 LSA type?

Router-LSA

Network-LSA

ASBR- Summary-LSA

AS-External -LSA

QUESTION 211
In the USG series firewall, what is the security level of the DMZ zone?

100

QUESTION 212
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.

There is only one matching order and cannot be modified.

QUESTION 213
Which of the following attacks areDoS ( Denial of service) attack?

single packet attack

Source IP address spoofing attack

man-in-the-middle attack

flood attack

QUESTION 214
Assuming that the shaping rate of a port is 100Mbps, the input bandwidth of each service on the interface and the PIR of the IP configuration are as follows: After the first round of scheduling, what is the bandwidth allocated by the EF queue?

30M

15M

90M

25M

QUESTION 215
Which of the following about the characteristics of multi-instance CE is incorrect?

due to MThe CE device is already bound to the VPN, so there is no need to bind the VPN to the PE connected to the MCE device.

MCEThe device can determine the source of the routing information according to the interface that receives the routing information, and maintain it in the routing forwarding table of the corresponding VP.

The implementation principle of MCE is to create its own routing and forwarding table for different VPNs on the MCE device and bind it to the corresponding interface.

configureMCE,A CE can be connected to multiple VPNs at the same time, which not only realizes complete isolation of services between different VPN users, but also reduces the investment cost of network equipment.

QUESTION 216
Which of the following options may affect the establishment of IBGP neighbors?

iBGP-Multi-hop not configured

Authentication failed

IGP routing failure

Inconsistent BGP protocol versions

Explanation
IBGP does not need to configure multi-hop, and can use loopback to establish neighbors. EBGP is not directly connected to the interface to establish a neighbor, it needs to refer to multiple hops.

QUESTION 217
