NO.99 On an OSPF network, if a router receives an update of an LSA that exists in the local LSDB, the router updates the LSDB and floods the LSA.

TRUE

FALSE

NO.100 The filter-policy 2000 export command is run in an ISIS process. Which of the following statements about the functions of a filter policy is false?

Is used together with the route import function to advertise some imported external routes to neighbors.

If this command is not run, the device by default advertises all routes that ISIS Imports form external routing protocols.

Controls the advertisement of routes generated by the device.

Filters LSPs to be advertised.

Bootstrap

Graft

Assert

NO.102 The following figure shows the OSPF network of an enterprise and the OSPF configurations of R1. Which of the following statements is false about the network?

R2 can access the server.

GE 0/0/1 of R1 cannot send OSPF packets.

The network segment to which GE 0/0/1 of R1 belongs cannot be advertised.

GE 0/0/1 of R1 cannot accept OSPF packets.

NO.103 A monitoring plane usually comprises the monitoring units of main control boards and interface boards. This plane can monitor the system environment independently. Which of the following environment monitoring functions can be provided by the monitoring plane?

Voltage monitoring

Temperature monitoring

Fan control

NO.104 RSTP provides different functions in different scenarios. Which of the following statements Is false?

After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period

The role of the designated port that is enabled with root protection cannot be changed

If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation

When the designated port enabled with root protection receives optimal RST BPDUs, the port enters the Discarding state and does not forward packets. If the port does not receive optimal RST BPDUs within a certain period of time, the port will automatically restore to the Forwarding state

NO.105 An enterprise administrator wants to configure single-hop BFD to implement fast detection of direct links.
Which of the following configurations are mandatory?

Configure the remote discriminator of a BFD session.

Configure the local discriminator of a BFD session.

Configure a multicast IP address for BFD.

Enable BFD globally.

NO.106 Which of the following statements about stack split is false?

After a stack splits, the MAC addresses of the two stacks change immediately.

If the master and standby switches are still in the same stack after the stack splits, the slave switches separated from the original master and standby switches re-elect the master and standby switches due to protocol packet timeout.

If the master and standby switches are in two stacks after the split, the stack where the original master switch resides updates the topology and selects a new standby switch. The original standby switch becomes the master switch in the new stack and a new standby switch is elected.

After a stack splits, multiple stacks have the same IP address and MAC address. To prevent network faults, the stacks perform MAD detection. The stack that fails the MAD detection shuts down all physical ports except reserved ports.

NO.107 On an OSPF network, an algorithm is used to prevent loops within an area, but loops may occur between areas. Therefore, OSPF defines a loop prevention mechanism for inter-area routes. Which of the following statements are true about the loop prevention mechanism?

Inter-area routes cannot be directly transmitted between non-backbone areas.

All non-backbone areas must be directly connected to area 0.

Inter-area routes need to be forwarded through area 0.

An ABR cannot inject Type 3 LSAs that describe routes to a network segment in an area back to the same area.

NO.108 During the DHCP interaction process, the DHCP server and client exchange various types of packets. Which of the following packets is not sent from the client to the server?

DHCP Release

DHCPNAK

DHCP Request

DHCP Discover

NO.109 An edge port is a new port role added to RSTP to overcome the disadvantages of STP. Which of the following statements is false about this port role?

The port does not participate in RSTP calculation.

The port can directly enter the Forwarding state from the Discarding state.

After receiving a configuration BPDU, the port is still in the Forwarding state.

The Up and Down states of the port do not cause network topology changes.

NO.110 The filter-policy 2000 export command is run in an ISIS process. Which of the following statements about the functions of a filter policy is false?

Is used together with the route import function to advertise some imported external routes to neighbors.

If this command is not run, the device by default advertises all routes that ISIS Imports form external routing protocols.

Controls the advertisement of routes generated by the device.

Filters LSPs to be advertised.

NO.111 Four routers run IS-IS and have established adjacencies. The area IDs and router levels are marked in the following figure. R1 and R2 are connected through a PPP link, and R3 is the DIS. Which of the following statements are true?

R3 periodically sends CSNPs to implement Level-2 LSDB synchronization.

R2 sends an LSP to R3 and R4 in unicast mode.

If R1 sends an LSP, R2 needs to send a PSNP for acknowledgment.

NO.112 When multiple access channels are set for the same access requirement, the insecure access channels are not used and secure access channels are selected in normal cases. Which of the following are secure access channels?

HTTPS

Telnet

SNMPv2

SFTP

NO.113 On an IS-IS network, each router can generate LSPs. Which of the following events trigger the generation of a new LSP?

Periodic updates occur.

Inter-area IP routes change.

The IS-IS interface cost is increased.

NO.114 See the command output of a router below. Which of the following statements is true?
<R2>display ospf interface GigabitEthernet 0/0/0 verbose
OSPF Process 1 with Router ID 10.0.2.2
Interface: 10.0.12.2 (GigabitEthernet 0/0/0)
Cost: 1 State: BDR Type: Broadcast MTU: 1500
Priority: 1
Designated Router: 10.0.12.1

The router ID is 10.0.12.2.

The interface cost is 1500.

This router is a BDR.

The interface IP address is 10.1.12.1.

NO.115 What is the default sending interval of BFD packets?

10s

100ms

1000ms

NO.116 Which of the following statements is false?

If the current DR fails, the current BDR automatically becomes a new DR, and a BDR will be elected again.

A device with a higher router priority has a higher election priority.

When a router with the highest router priority joins an OSPF network, this router will become the new DR.

If two devices have the same router priority, the device with a larger router ID has a higher election priority.

NO.117 After HSB is configured, the HSB channel fails to be established and cannot back up information on the active device to the standby device. What are the possible causes for this HSB function failure?

The TCP channel is not established.

The retransmission count and interval for HSB service packets are different on the two devices.

The two ACs have the same priority.

The source IP address and port number of the local end are different from the destination IP address and port number of the remote end.

NO.118 RSTP provides different functions in different scenarios. Which of the following statements Is false?

After TC-BPDU attack defense function is enabled, you can set the number of times the switch processes TC BPDUs within a certain period

The role of the designated port that is enabled with root protection cannot be changed

If the edge port on the switch enabled with BPDU protection receives RST BPDU, the switch sets the edge port as a non-edge-port and triggers STP calculation
