Free Huawei H12-725_V4.0 Practice Exam with Questions & Answers | Set: 2

Comprehensive and Detailed Explanation:

Huawei's Anti-DDoS solution has three core components:

A. Detecting center→ Monitors and detects attack traffic.

B. Management center→ Controls and configures security policies.

D. Cleaning center→ Mitigates attack traffic and allows normal traffic.

Why is C incorrect?

"Zone" is not a specific Huawei Anti-DDoS component.

Comprehensive and Detailed Explanation:

VLAN authorization in Portal authentication requires additional configuration.

To assign VLANs dynamically:

RADIUSmust return VLAN attributesafter authentication.

TheWAC (Wireless Access Controller) must be configured to support dynamic VLAN assignment.

Why is this statement false?

VLAN authorization requires RADIUS attributes and WAC configuration—it is not automatic.

Comprehensive and Detailed Explanation:

IKEv1 Phase 1 (Main Mode) consists of six messages:

Messages 1 & 2 → Negotiate security proposals(encryption, authentication, and DH group).

Messages 3 & 4 → Exchange key-related information.

Messages 5 & 6 → Perform mutual authentication.

Why is B correct?

Messages 1 and 2 negotiate IKE proposalsbetween VPN peers.

Comprehensive and Detailed Explanation:

Inbound bandwidth= Trafficenteringthe firewall.

Outbound bandwidth= Trafficleavingthe firewall.

Correct answer:

A. Private → Public traffic is controlled by outbound bandwidth.

Why are the other options incorrect?

Bis incorrect because public → private traffic is controlled byinbound bandwidth, not outbound.

Cis incorrect because inbound bandwidth does not apply to private → public traffic.

Dis incorrect because public → private traffic is controlled by inbound bandwidth.

Comprehensive and Detailed Explanation:

Virtual system resource allocation can bemanual or shared.

Manual allocationrequires configuring aresource class, defining aquota, and binding it to a virtual system.

Why is D false?

Quota-based resources are not automatically allocated.

An administrator must defineresource quotas.

Comprehensive and Detailed Explanation:

IPsec does not support non-IP traffic (e.g., multicast, routing protocols, or legacy protocols like IPX).

GRE over IPsec allows encapsulation of:

A. IPX→ Legacy protocol supported via GRE.

B. VRRP→ Uses multicast, which GRE supports.

C. IPv6→ GRE tunnels can carry IPv6 over IPv4.

D. OSPF→ Uses multicast (224.0.0.5 & 224.0.0.6), requiring GRE.

Why are all options correct?

GRE over IPsec is required for non-unicast and legacy protocols.

Comprehensive and Detailed Explanation:

Deploying multiple egress linksensures:

Redundancy→ If one link fails, another remains active.

Load balancing→ Traffic can be distributed across multiple links.

High availability→ Reduces downtime.

Why is this statement true?

Enterprise networksbenefit from multiple egress links.

Comprehensive and Detailed Explanation:

IPsec VPN only supports IP unicast traffic.

Non-IP unicast packets (such as multicast and broadcast) are not natively supported.

To transmit multicast traffic over IPsec, GRE over IPsec is required.

Why is this statement true?

Standard IPsec VPN does not support non-IP unicast packets.
