NO.122 On a router,SRv6is enabled, and the configurations shown below are performed. Which of the following statements about the configurations are correct?
[Router-segment-routing-ipv6] locator srv6_locator1 ipv6-prefix 2001:DB8:ABCD::/64 static 32

The locator of this node is2001:DB8:ABCD::.

The static segment of the node occupies32 bits.

The dynamic segment of the node occupies32 bits.

The Args field of this node occupies32 bits.

NO.123 Which of the following statements about static VXLAN tunnel configuration are correct?

On an NVE interface, the destination address of a VXLAN tunnel is specified based on the address in the ingress replication list. You can create one NVE interface for multiple VXLAN tunnels.

An NVE interface can be associated with multiple VNIs. Therefore, you can create one NVE interface when there are multiple BDs.

One NVE interface must be created for each VXLAN tunnel, and the source and destination IP addresses must be specified for the NVE interface. Therefore, the number of NVE interfaces is the same as the number of VXLAN tunnels on the VTEP.

One NVE interface must be created for each BD. If there are multiple BDs, multiple NVE interfaces must be created.

NO.124 The following description of the TTL in the MPLS Header is correct:

A TTL that acts like an IP header and is used to prevent message loops

To control label distribution

Limit LSR

Control of upstream devices for label distribution

NO.125 Which of the following types of LSAs does OSPF use to support SR-MPLS?

Type 7 NSSA External LSA

Type 10 Opaque LSA

Type 1 Router LSA

Type 2 Network LSA

NO.126 On a campus network, which of the following problems may occur when you manually create a static VXLAN tunnel?

Although the static VXLAN tunnel mode supports the distributed gateway scenario, the configuration involves a heavy workload and is complex to adjust.

Remote MAC addresses can be learned by the VTEP only through data flooding.

A static VXLAN tunnel also uses corresponding protocols on the control plane, which consumes device resources.

If N devices need to establish static VXLAN tunnels, a maximum of N(N -1)/2 tunnels need to be manually configured, which involves a heavy workload.

NO.127 iMaster NCE-Campus provides the terminal identification function to display the terminal type, operating system, and manufacturer information.

TRUE

FALSE

NO.128 In the Huawei CloudCampus Solution, which of the following devices can go online through the registration query center?

Switch

Firewall

NO.129 The following statement about the security alliance SA in IPSec is incorrect

SA is uniquely identified by a triple that includes the security parametric reference SPI (Security Parameter Inder), the source IP address, and the security protocol number (AH or ESP)

Use the display ipsec command to view the encryption algorithm used with another IPSec peer, the traffic of interest, and so on.

IPSec only supports encrypting data using symmetric encryption algorithms.

A two-way SA must exist between IPSec peers to establish an IPSec VPN connection

NO.130 MPLS supports both static and dynamic LSP establishment. Which of the following protocols cannot dynamically establish LSPs in MPLS TE scenarios? (Select all that apply)

OSPF

RSVP-TE

BGP

IS-IS

NO.131 Which of the following options uses an alternate channel to enable communication between IPV6 addresses?

DualStack

6to4

ISATAP

NAT64

NO.132 When you configure a virtualized campus network on iMaster NCE-Campus and enable external networks to connect to the Internet, iMaster NCE-Campus will automatically deliver a specific route to direct traffic to the corresponding external network.

TRUE

FALSE

NO.133 Which of the following statements isincorrectabout adding devices on a virtualized network deployed using iMaster NCE-Campus?

iMaster NCE-Campus allows users to add devices in batches.

iMaster NCE-Campus allows users to add devices by device role.

iMaster NCE-Campus allows users to add devices by device ESN.

iMaster NCE-Campus allows users to add devices by device model.

NO.134 In a shared network, what mechanism does PIM-SM use to prevent duplicate traffic?( Single choice questions).

BSR/RP mechanism

Assert mechanism

Join/Prune mechanism

NO.135 Regarding the domain-authentication-mode md5 hello command in the ISIS process, the correct explanation is
?

ISIS authentication cannot be applied in IPv6 environments.

This command is mainly used to make is the ISIS Hello message carry authentication information during the transmission process.

All router domain authentication methods of the same routing domain are MD5, the password is hello, and lS-IS SNP and LSP will spread normally.

outing domain authentication is primarily used to allow level-1 and Level-2 SNP and LSP messages to carry authentication information during delivery.

NO.136 What are the types of link types included in OSPF’s route LSA?

Stubnet

P-2-P

VLINK

Fransnet

NO.137 You have developed a third-party Portal authentication application and connected it to iMaster NCE-Campus to perform Portal authentication for Wi-Fi users. After connecting to Wi-Fi, a user will be redirected to the login page pushed by the authentication application when visiting any website for the first time.

TRUE

FALSE

NO.138 Prefix segments and adjacency segments are globally visible and unique.

TRUE

FALSE
