QUESTION 67
IS-IS supports multiple instances and multiple processes, that is, one IS-IS router, multiple VPN instances can be configured to be associated with multiple IS-IS processes. Which of the following descriptions about IS-IS multi-instance and multi-process are correct? (Multiple choice)

One IS-IS process can only be associated with one VPN instance

If an IS-IS router creates multiple IS-IS processes, each process does not affect each other and is independent of each other

1 IS-IS process can be associated with multiple different VPN instances

1 VPN instance can be associated with multiple different IS-IS processes

QUESTION 68
A campus deploys both IPv4 and IPv6 networks for service testing, and runs IS-IS to achieve network interconnection. The IS-IS routing protocol has good scalability and is widely used in the existing network. Which of the following statements is true about IS-IS scalability? (Multiple choice)

IS-IS uses the TLV structure to construct packets, making IS-IS more flexible and extensible

For IS-IS, adding new features only needs to add new TLVs

IS-IS needs to add TLV to carry IPv6 address information in order to support IPv6

NLPID is a new TLV added by IS-IS to support IPv6

QUESTION 69
As shown in the figure, OSPF is enabled on all interfaces of the router, and the cost value of the link is advertised in area 0 according to the Loogback0 of R2 as shown in the figure, then in area 1, both R2 and R3 will transmit 10.0 in the form of Typae3 LSA .2.2/32 routing information.

TRUE

FALSE

QUESTION 70
Which of the description of business priority in DSCP is correct?

AF has higher priority than EF

AF11 has a higher packet loss rate than AF12

CS has the highest priority

AF11 has higher priority than AF4

QUESTION 71
OSPFV2 is an IGP running on an IPV4 network; OSPFv3 is an IGP running on an IPV6 network. The basic working mechanism of OSPFv3 is the same as that of OSPFv2, such as the election of DR and BDR.
As shown in the figure, an engineer uses three routers to test IPv6 services. He wants to realize the interconnection of IPv6 networks by running OSPFv3.

Which of the following statements about the election of the network DR is correct?

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

After the network converges, a new device R4 is added to the broadcast link

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

After the network converges, R1 is the DR

QUESTION 72
Assuming that the neighbor relationship between BGP routers has been established successfully, the configuration on R1 is as shown in the figure.

Which router can the routing entry 10.10.10.0/24 published by 1 be delivered to the farthest?

QUESTION 73
In order to improve the stability of STP operation, the network administrator decides to configure some features or protection mechanisms of STP on the switch. Which of the following configuration ideas is correct?

Configure the user’s access port as an edge port to prevent users from accessing the switch on this port

Configure Root Guard on the user’s access port to ensure that the user cannot access a high-priority switch

Configure Loop Guard where there is a loop in the network to ensure that the loop is always blocked

After configuring BPDU Guard, the switch will check the validity of each BPDU received to prevent forged BPDU attacks

QUESTION 74
There are many types of LDP messages. Which of the following functions can a session message implement? (Multiple choice)

Monitor the integrity of the TCP connection of the LDP Session

Terminate the outstanding Label Request Message

Release Tag

Negotiate parameters during LDP Session establishment

QUESTION 75
Regarding the description of OSPF’s neighbor relationship failure, which of the following statements is false?

Stalling in ExStart state may be due to MTU mismatch between neighboring routers

Stalling in the lnit state indicates that the router has received the neighbor’s Hello packet, but the Hello packet does not contain the OSPF Router ID of the router

The two router databases are synchronized, and an error occurs in the SPF calculation. It must be because the router ID is duplicated

For a pair of DR Others on an Ethernet link

QUESTION 76
What is the value of the linkage between OSPF and BFD?

Any change in BFD state will not affect OSPF neighbor state

The sending interval of BFD packets can reach the millisecond level, which is slower than OSPF sensing link status

The hello sending interval of OSPF is in seconds, which is faster than BFD sensing link status

BFD detected at the millisecond level

QUESTION 77
By default, which of the following security MAC address types will be lost after the device restarts?

Black Hole MAC Address

Secure Static MAC Address

Secure Dynamic MAC Address

Sticky MAC address

QUESTION 78
During the daily troubleshooting process, engineers may need to view some alarm information of the device. Run the terminal ( ) command to enable the terminal to display the debugging/log/alarm information function sent by the information center. (Please use English lowercase letters to complete the command, and the command cannot be abbreviated)

monitor

QUESTION 79
OSPFv3 adopts the same route advertisement method as OSPFv2: it is advertised through the network command in the OSPFv3 area view.

TRUE

FALSE

QUESTION 80
What can we infer from this graph? (Multiple choice)

There is a route entry on R1 to 172.16.1.4/32

There is no IS-IS routing entry in R1’s IP routing table

There are 6 routing entries generated by IS-IS in the IP routing table of R1

R1 has no route entry to 172.16.1.4/32

QUESTION 81
Which of the following statements about IPSG is false?

IPSG can prevent IP address spoofing attacks

IPSG is a source IP address filtering technology based on Layer 3 connection

The IPSG can enable the IP packet inspection alarm function, and link the network management to alarm

IPSG can prevent the host from changing the IP address privately

QUESTION 82
When encountering network failures, engineers often use hierarchical fault handling because all models follow the same basic premise, and when all of a model’s lower-level structures are working properly, its higher-level structures will work as expected. Please match the following check items to the corresponding levels according to the hierarchical method.

QUESTION 83
There is a concept of forwarding equivalence class (FEC-Fowarding Equivalence Class) in MPLS, so FEC cannot be allocated based on which of the following criteria?

Class of Service

Fragment offset

Application Protocol

Destination Addess

QUESTION 84
In order to quickly detect network link failures, which of the following protocols can we deploy?

BFD

RSTP

ISPF

Smart-Link

QUESTION 85
Which description is correct about the DHCP address pool? (Multiple choice)

Configure the address allocation method based on the global address pool, which can respond to DHCP requests received by all ports

Only when the address allocation method based on the global address pool is configured, can you set the P address range that does not participate in automatic allocation

Configuring the interface-based address assignment method will only respond to the DHCP request of the interface

Configure interface-based address allocation, which can respond to all ports receiving DHCP requests
