Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q15-Q20):

NEW QUESTION # 15
L2TP does not provide security encryption. Therefore, other security measures, such as IPsec, are required to ensure the security of the entire tunnel for data transmission.

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. What is L2TP (Layer 2 Tunneling Protocol)?
* L2TP is a tunneling protocol used to transport Layer 2 frames over IP networks.
* It is commonly used to establish VPNs but does not provide built-in encryption or security for the transmitted data.
2. Why L2TP Requires Additional Security Measures:
* Since L2TP does not encrypt traffic, it is vulnerable to eavesdropping and tampering.
* To secure L2TP tunnels, it is often paired with IPsec, which provides strong encryption and authentication. The combination of L2TP and IPsec is known as L2TP/IPsec.
3. Why the Statement is TRUE:
* The statement accurately describes the limitation of L2TP (lack of encryption) and the need for additional security measures like IPsec.


NEW QUESTION # 16
What are the main components of the SNAP address used by the IS-IS protocol? (Multiple choice)

Answer: A,B,C


NEW QUESTION # 17
Which of the following statements regarding OSPF multi-instance is false?

Answer: C

Explanation:
OSPF process IDs are locally significant and do not need to match between routers to form neighbor relationships. The other statements correctly describe the behavior of OSPF multi-instances, making Option C false .


NEW QUESTION # 18
VRRP defines three states. Only the device in which state can forward packets destined for a virtual IP address?
(Write in full and capitalize the first letter.)

Answer:

Explanation:
Master
Explanation:
VRRP defines the following states:
* Initialize - The router is starting up or has not joined a VRRP group.
* Backup - The router is in standby and monitors the Master.
* Master - The only state where the device forwards traffic for the virtual IP address.
Only the router in the Master state owns the virtual MAC and responds to ARP for the virtual IP.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"In VRRP, only the Master forwards packets destined for the virtual IP address. Backup routers take over only if the Master fails." (Chapter: VRRP Concepts - Section: State Roles and Transitions)


NEW QUESTION # 19
IGMPv1 defines a mechanism for electing queriers when multiple routers exist in a shared network.

Answer: B
