TRUE

FALSE

QUESTION 264
When configuring dual-link hot backup, the engineer configured the CAPWAP heartbeat detection interval to be 20 seconds, and the dual-link backup function is enabled, then how long does the AP detect the timeout of the main link and perform the main-standby switchover?

75 seconds

20 seconds

60 seconds

90 seconds

QUESTION 265
OSPF supports area authentication and interface authentication. If both authentication methods are configured at the same time, interface authentication is better than area authentication.

TRUE

FALSE

QUESTION 266
BGP Speaker only notifies neighbors of changed routes.

True

False

QUESTION 267
On the VRP platform, when we introduce OSPF routing to ISIS, if COST is not specified, the cost value will be set to 16 by default.

True

False

QUESTION 268
Which of the following description about OSPF routing aggregation is wrong?

Any router in OSPF can perform route aggregation operations

Inter-area route aggregation refers to the aggregation of routing information of the same prefix, and only one route is advertised to other areas

OSPF has two route aggregation methods: ABR aggregation and ASBR aggregation

Through route aggregation, routing information can be reduced, thereby reducing the size of the routing table and improving the performance of the router

QUESTION 269
Which of the following statements about BFD is correct? (Multiple choice)

Use a single mechanism to detect all types of media and protocol layers to achieve a unified detection mechanism for the entire network

BFD can provide connectivity detection across networks

The upper layer application provides parameters such as detection address and detection time to BFD

Provides light-load, short-duration detection of paths between adjacent forwarding engines

QUESTION 270
Which of the following statements about VLAN hot backup is wrong? (Multiple choice)

In dual-link hot backup, the priority of the active and standby ACs can be configured to be the same to achieve backup in load sharing mode

When configuring VRRP hot backup, you can configure the priority of VRRP to determine the primary and backup colors of the AC device

When configuring VRRP hot standby, the active and standby ACs must be on the same Layer 2 network

In VRRP hot backup, the active and standby ACs can be on different Layer 2 networks and communicate with each other through Layer 3 for backup

QUESTION 271
The LSDB output of a router R2 is shown in the figure. According to the analysis of the content in the figure, which of the following options is wrong?

Area boundary route aggregation exists in Area1

ASBR exists in Area 2, and the Router ID of ASBR is 6.6.6.6

R2 is deployed in the backbone area, and R2 is an ABR

There is no Stub area in the entire environment involved in the figure

QUESTION 272
What is the security level of the Untrusts zone in the USG series firewall?

QUESTION 273
The shortest path from the multicast source to the receiver becomes the shortest path tree SPT.

TRUE

FALSE

QUESTION 274
Which of the following descriptions about configuring the dual-machine hot backup function in the WLAN network is wrong?

When dual-link hot backup is switched over, due to the long switching time, the business data forwarded by the tunnel will be interrupted during this period, and new users will not be able to go online, and the online users will not be able to roam.

When configuring dual-link hot backup, after the active AC completes the service configuration, execute the commit command to send the configuration to the AP, and then complete the configuration of the standby AC

When configuring dual-link backup, you need to use the commit command on the active AC to send the configuration to the AP after the active and standby ACs have completed the service configuration.

QUESTION 275
As shown in the figure, the ISIS neighbor relationship between R1 and R2 has just been established, and the database synchronization process between R1 and R2 is correct?

The packet sent by R1 to R2 is a Hello packet.

The packet sent by R1 to R2 is an LSP packet.

The packet sent by R1 to R2 is a PSNP packet.

The packet sent by R1 to R2 is a CSNP packet.

QUESTION 276
BGP prefers the route with the best Origin attribute value. Origin attribute values are: EGP, IGP, ().

QUESTION 277
Which of the following options is the minimum total length of the NET address in IS-IS?

8 bytes

16 bytes

2 bytes

20 bytes

QUESTION 278
Routing tools that are not only used for BGP routing protocol have (Multiple choice)

as-path-filter

ACL

IP-Prefix

community-filter

QUESTION 279
Which of the following statements about stack splitting is wrong?

If the master switch is in two stack systems after the stack is split, the stack system where the original master switch is located updates the topology and re-designates the master switch.

After the stack splits, the MAC addresses of the two stack systems will change immediately

After splitting, multiple stack systems will have the same IP address and MAC address. In order to avoid network failures, the stack will perform MAD detection. The party that fails the MAD detection competition will close all physical ports except reserved ports.

If the master and backup switches are still in the same stack system after the stack splits, the slave switch separated from the original master and backup switches will re-elect the master and backup switches due to the timeout of the protocol message

QUESTION 280
What is the BFD version number supported by the VRP version?

version 3

Version 2

Version 1

Version 4

QUESTION 281
If the transformation of the network in the project will affect the business running on the existing network, then the implementer needs to formulate strict implementation process specifications and risk avoidance measures. We generally define such projects as cutover projects.

TRUE

FALSE

QUESTION 282
Which of the following about the description of the information contained in the OPEN message in the EGP is incorrect?

QUESTION 284
Which of the following descriptions about stateful inspection firewalls is correct?

When the state inspection firewall checks the packets, the preceding and following packets of the same connection are not relevant.

The state inspection firewall needs to match the rules for each packet entering the firewall

The state inspection firewall only needs to match the access rules for the first data packet of the connection, and the subsequent packets of the connection are directly matched in the state table

Because the UDP protocol is a connectionless protocol, the state detection firewall cannot match the state table of UDP packets
