Question 651

Which of the following statements regarding MUX VLAN is true?

The MUX VLAN contains a principal VLAN and subordinate VLANs. The principal VLAN and subordinate VLANs cannot communicate.

The MUX VLAN contains a principal VLAN and subordinate VLANs. The subordinate VLANs are classified into subordinate separate VLANs and subordinate group VLANs. The interfaces in the subordinate group VLAN can communicatewith each other.

The interfaces between subordinate separate VLANs can communicate with each other, but cannot communicate with the interfaces in the principal VLAN.

The principal VLAN and subordinate VLANs cannot communicate.

Question 652

Huawei switches provide port isolation. Which of the following statements regarding port isolation is false?

You can configure Layer 2 and Layer 3 isolation or Layer 2 isolation and Layer 3 interworking.

Huawei switches support 64 isolation groups numbered 0 to 63.

If interface A is isolated from interface B, packets sent from interface A cannot reach interface B, but packets sent from interface Ð' can reach interface A.

FE interfaces, GE interfaces, XGE interfaces, and Eth-Trunks can be isolated from one another, but an interface cannot be isolated from itself or from the management interface unidirectionally. In addition, an Eth-Trunk cannot beisolated unidirectionally from its member interfaces.

Question 658

Which of the following statements regarding forwarding equivalence class (FEC) in MPLS are false? (Multiple Choice)

Packets with the same FEC are processed differently on a MPLS network.

FECs can be divided flexibly by source IP address, destination IP address, source port, destination port, protocol type, VPN, or any combinations of them.

MPLS classifies packets with the same forwarding processing mode into one FEC.

One FEC has only one unique label marker.

Question 659

On a carrier's MPLS VPN network, PE1 and PE2 transmit data packets between VPNs. After PE1 receives VPN route 172.16.1.0/24 from a client, it converts the route into a VPNv4 route and distributes label 1027 to the packet. After the packet arrives at PE2, PE2 distributes label 1025 to the packet. When a client on PE2 accesses this route, what are the outer and inner labels in the packet transmitted over the carrier network?

Outer label: 1027; inner label: 1025

Outer label: 1025; inner label: 1025

Outer label: 1027; inner label: 1027

Outer label: 1025; inner label: 1027

Question 660

A VPN instance is also called a VPN routing and forwarding (VRF) table. Which of the following statements is false?

VPN instances on a PE are independent of each other.

Each VPN instance can be regarded as a virtual router, which maintains an independent address space and has one or more interfaces connected to the VPN.

A PE maintains multiple routing and forwarding tables, including a public routing and forwarding table and one or more VRFs.

A VPN instance can be bound to multiple sites. Multiple sites can be bound to one VPN instance.
