Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q298-Q303):

NEW QUESTION # 298
The advantages of network address translation (NAT) technology do not include which of the following?

A. Allow users to retain internal solutions while changing operators, enhancing the flexibility of connecting to public networks
B. Can effectively reduce the consumption of public IP addresses
C. Because address translation can hide the user address of the internal network and improve the security of the internal network, a router with NAT function can directly replace the firewall
D. Users with private addresses can access the Internet

Answer: C

NEW QUESTION # 299
A Layer 2 switch supports multiple types of Ethernet interfaces. Similar to a trunk interface, a hybrid interface allows data frames from multiple VLANs to pass through. In addition, you can determine whether data frames from a VLAN sent out from a hybrid interface are tagged or untagged.

A. TRUE
B. FALSE

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Understanding Hybrid Interfaces on a Layer 2 Switch:
* Layer 2 switches support different interface types, such as access, trunk, and hybrid interfaces.
* A trunk interface allows traffic from multiple VLANs to pass through, but frames belonging to the native VLAN are sent untagged, while all other VLAN frames are tagged.
* A hybrid interface is more flexible:
* It allows traffic from multiple VLANs to pass through, just like a trunk interface.
* However, you can configure whether frames for specific VLANs are tagged or untagged as they leave the interface. This feature is useful in certain networking scenarios, such as connecting devices that do not support VLAN tagging.
2. Key Differences Between Trunk and Hybrid Interfaces:

3. Why the Statement is TRUE:
* The statement accurately describes the functionality of a hybrid interface:
* It supports traffic from multiple VLANs.
* It allows administrators to configure whether outgoing frames are tagged or untagged for specific VLANs.
4. Summary:
* The statement is TRUE because hybrid interfaces on a Layer 2 switch support traffic from multiple VLANs and allow flexible tagging configurations.

NEW QUESTION # 300
The following figure shows a campus network. IS-IS is configured on all routers, and the network runs normally.

By default, which of the following routers have specific routes on the entire network?

A. R1
B. R7
C. R2
D. R3

Answer: C,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
In IS-IS, routes are distributed differently based on router levels:
Level-1 (L1) routers # Maintain specific routes only within their own area.
Level-2 (L2) routers # Maintain specific routes for the entire network (inter-area routing).
Level-1-2 (L1/L2) routers # Store both L1 and L2 routes and act as area border routers.
In the diagram, R2 and R3 are L1/L2 routers, meaning they store specific routes for both their area and other areas.
R1 is only an L1 router, meaning it only has intra-area routes, and R7 is an L2-only router, meaning it does not store all specific routes.
Therefore, R2 and R3 have specific routes for the entire network.
# Reference: Huawei HCIA-Datacom Study Guide, IS-IS Routing Levels and Route Distribution.

NEW QUESTION # 301
