- B. TRUE
Correct Answer: B 🗳️

Fill in Blank
The ________ command can be run to completely isolate Layer 2 and Layer 3 of different interfaces in a VLAN. (Use lowercase letters to supplement the command, which cannot be abbreviated.)
Correct Answer:
portisolateenable
Explanation:
The command port-isolate enable is used on Huawei switches to completely isolate traffic at both Layer 2 and Layer 3 between different interfaces within the same VLAN. This isolation prevents any communication between isolated ports-even if they belong to the same subnet or VLAN-making it a critical security feature in multi-tenant environments.
Usage Context:
Often used in shared service or hotel network scenarios.
Can be applied in access port configurations.
Does not require additional VLAN creation or private VLAN features.
Huawei Datacom Reference:
"To completely isolate Layer 2 and Layer 3 communication between interfaces in the same VLAN, run the port-isolate enable command under the interface view." (Source: HCIE-Datacom Study Guide V3.0 - Chapter: VLAN & Security Technologies, Section: Port Isolation)
In the following figure, OSPF is enabled on all router interfaces. The IP addresses marked in the figure belong to Loopback0 of the routers.
The Loopback0 addresses of R1 and R2 are advertised in Area 1, the Loopback0 address of R4 is advertised in Area 0, and the Loopback0 addresses of R3 and R5 are advertised in Area 2. Given this, which of the following IP addresses can ping each other?
- A. 10.0.2.2 and 10.0.3.3
- B. 10.0.4.4 and 10.0.2.2
- C. 10.0.3.3 and 10.0.5.5
- D. 10.0.2.2 and 10.0.5.5

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.
- A. FALSE
- B. TRUE
Correct Answer: A 🗳️
Explanation: Only visible for Test4Sure members. You can sign-up / login (it's free).
When MPLS/BGP IP VPN is deployed, which of the following statements is incorrect about BGP route exchange between PEs and CEs?
- A. In a Hub&Spoke scenario, when Hub-CE and Hub-PE run an IGP for communication, EBGP cannot be configured on Spoke-PE or Spoke-CE.
- B. In a CE multi-homing scenario, the BGP AS number replacement function may cause routing loops. BGP SoO can be used to prevent routing loops at a VPN site.
- C. When PEs and CEs use BGP to exchange routing information, you do not need to import private network routes to BGP on PEs.
- D. In a scenario where PEs and CEs use BGP to exchange routing information, if two VPN sites have the same private AS number, the AS number replacement function can be used to replace the AS number in a received private network route with any specified AS number. This prevents routes from being discarded because of repeated AS numbers.
