Questions # 22:

(On a VXLAN-based virtualized campus network, terminals communicate with each other through VXLAN tunnels. When the campus network needs to communicate with external networks, the data must pass through border nodes.)

Options:

A.

TRUE

B.

FALSE

Questions # 23:

(Refer to the following figure.

Question # 23

Which of the following solutions can be used to prevent users from accessing the network using statically configured IP addresses?)

Options:

A.

DAI + IPSG

B.

DHCP Snooping + DAI

Questions # 24:

(The following figure shows the MAC address table of a Layer 2 VXLAN gateway. Which of the following statements are true?Choose all that apply.)

Question # 24

Options:

A.

Both 0000-0000-0010 and 5489-9893-48a3 belong to BD 10 and are in the same Layer 2 broadcast domain.

B.

The outbound interface corresponding to 5489-982d-77e2 is GE1/0/1.20. Because this interface belongs to BD 20, the host with 5489-982d-77e2 can directly communicate with the host with 5489-9893-48a3 at Layer 2.

C.

The MAC address entry with the outbound interface 10.3.3.3 is learned from the remote VTEP through the VXLAN tunnel.

D.

The outbound interface corresponding to 5489-9893-48a3 is GE1/0/1.10, which belongs to BD 10.

Questions # 25:

(Which of the following is the mapping between VNIs and BDs in VXLAN implementation?)

Options:

A.

1:1

B.

N:1

C.

N:M

D.

1:N

Questions # 26:

(In the Huawei CloudCampus Solution, which of the following deployment modes are supported by Huawei switches?)

Options:

A.

Huawei registration center

B.

DHCP Option 148

C.

Web interface

D.

CLI

Questions # 27:

(When you configure a virtualized campus network on iMaster NCE-Campus, Fit APs can immediately go online after you add them to iMaster NCE-Campus.)

Options:

A.

TRUE

B.

FALSE

Questions # 28:

(DHCP dynamically configures and centrally manages IP addresses of hosts. Which of the following statements about DHCP is false?)

Options:

A.

If only the gateway and DNS server information needs to be delivered to a DHCP client, the DHCP Offer message sent by the DHCP server to the client does not carry the Options field.

B.

The Options field in DHCP messages uses the type-length-value (TLV) structure and can carry parameters such as the NTP server address, AC address, and log server address.

C.

DHCP supports static IP address allocation, in which it assigns fixed IP addresses to specified terminals.

D.

When a DHCP client and a DHCP server are located on different Layer 3 networks, a DHCP relay agent is needed for forwarding packets between the DHCP client and server.

Questions # 29:

(Which of the following statements about the fabric global resource pool isfalse?)

Options:

A.

A bridge domain is a Layer 2 broadcast domain used to forward data packets on a VXLAN.

B.

VLANs for connecting to external networks, VLANs for connecting to network service resources, and VLANs for connecting underlay devices are allocated from the VLAN resource pool.

C.

A VXLAN network identifier identifies a VXLAN.

D.

Configure a service VLAN pool when you need to configure external gateway interconnection VLANs, network service resource interconnection VLANs, management VLANs for policy association, and VN access VLANs.

Questions # 30:

(Refer to the following routing entries queried using a command on the VTEP. Which of the following statements about these routes are true?)

Network(EthTagId/IpAddrLen/OriginalIp) NextHop

*>i 0:32:1.1.1.0 1.1.1.0

Route Distinguisher: 2:5

Network(EthTagId/IpAddrLen/OriginalIp) NextHop

*>i 0:32:1.1.1.0 1.1.1.0

Route Distinguisher: 2:7

Network(EthTagId/IpAddrLen/OriginalIp) NextHop

*>i 0:32:1.1.1.0 1.1.1.0

Options:

A.

These routes are Type 3 routes. If the VTEP IP address carried in these routes is reachable at Layer 3, a VXLAN tunnel to the peer end is established.

B.

These routes are Type 3 routes. After receiving these routes, the local end creates an ingress replication list.

C.

These routes are Type 2 routes and carry host IP addresses.

D.

These routes are Type 3 routes and carry the VTEP IP address.
