TRUE

FALSE

NO.121 According to this figure, we can judge:

R1 is configured with zone authentication

The device type of R1 is Leve-2

R1 sets routing domain authentication

NO.122 Suppose there are four flows a.b.c.d of 50M respectively, the total port bandwidth is 100M, traffic congestion occurs, and congestion management is performed on them. Among them, traffic a belongs to PQ queue scheduling, traffic b.c.d belongs to WFQ queue scheduling, and the weight ratio is 1:2:2. Which descriptions are wrong about the scheduling results for the four types of traffic? (Multiple choice)

Traffic a through 100M

Traffic a through 50M

Flow b passes through 10M, flow c and d pass through 20M respectively

NO.125 Regarding the sham link, which of the following descriptions is wrong?

A sham link is a link between two VPN instances, and each VPN instance must have an endpoint address of the sham link, which must be a Loopback with a 32-bit mask in the VPN address space on the PE router interface address

In order to forward the VPN flow through the MPLS backbone network, the routing cost of the sham link should be less than the OSPF routing cost of the backdoor road

The endpoint address of the sham link is published by BGP as a VPNv4 address. Routes that have passed through the sham link can also be imported into BGP in the form of VPNv4 routes.

Sham link can be configured in any area, it needs to be configured manually, and there must be a route to the destination address of the sham link (the sham link endpoint address of the peer PE) in the local VPN instance

NO.126 A router’s Network LSA is shown in the figure. Which of the following statements are correct? (Multiple choice)

This router is the DR

NO.127 When troubleshooting TELNET login failure, which step should be done first?

Check whether the client can ping the server

Check whether the number of users logging in to the device has reached the upper limit

Check whether ACL is configured in the VTY user interface view on the device

Check whether the protocol configuration allowed for access in the VTY type user interface view is correct

NO.128 As shown in the figure, on the R1 router, network administrator A can control the path of the traffic leaving AS100 after modifying the Local Preference value of the routing entry sent to R2 through the routing policy.

TRUE

FALSE

NO.129 A router runs OSPF, and the output information is shown in the figure. Which of the following statements is correct?

The type of the LSA is AS-external-LSA

The destination network described by this LSA is 10.0.23.0/24

The LSA in the figure is generated by this router

This device is an ABR

NO.130 The dynamic IP address assigned to the client by the DHCP server. Usually there is a certain rental period, which of the following description of the rental period is wrong?

The lease renewal timer is 50% of the total lease period. When the “lease renewal timer” expires, the DHCP client must renew the IP address

The rebinding timer is 87.5% of the total lease period

If the “rebinding timer” expires, but the client has not received a response from the server, it will always send a DHCP REQUEST message to the DHCP server that has previously assigned an IP address until the total lease expires.

If the client receives a DHCP NAK message within the lease period, the client will immediately stop using this IP address and return to the initialization state, and re-apply for a new IP address

NO.131 As shown in the figure, private network routing information is exchanged between PE1 and PE2 and their respective CEs through OSPF, and the same DomainID is configured on both PE1 and PE2. When routes are imported from BGP to OSPF on PE2, which of the following types of LSAs are possibly delivered to CE2? (Multiple choice)

Type1 LSA

Type3 LSA

Type7 LSA

Type5 LSA

NO.132 The preliminary investigation of the cutover project is mainly to communicate and coordinate with customers and other participants, and collect network information for analysis.

True

False

NO.133 In order to improve network security in a company, all internal computers of the company are assigned static MAC addresses. Now buy a new host with MAC address 5489-98FD-7B7F. The network administrator connects the host to the corporate network by executing the mac-address ( ) 5489-98FD-TB7F GigabitEthernet0/0/1 vlan 10 command. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)

static

NO.134 What are the three most important attributes of information security? (Multiple choice)

Confidentiality

Integrity

Availability

NO.135 EGP authentication can prevent illegal routers from establishing neighbors with BGP routers. BGP authentication can be divided into MD5 authentication and Keychain authentication. Which of the following BGP packets will carry BGP Keychain authentication information? (Multiple choice)

Open

Update

Notication

Keepalive

NO.136 A campus has deployed IPv6 for service testing. There are 4 routers in the network, running OSPFV3 to realize the interconnection of IPv6 networks.
As shown in the figure, an engineer checked the LSDB of R2 and intercepted one of the Link-LSAs.

Which of the following statements about the description of this LSA is correct? (Multiple choice)
