Pass the Huawei HCPA-IP Network H19-301_V3.0 Questions and answers with CertsForce

TheUSG6000E-Bfirewall doesnotsupport hardware bypass by default. If hardware bypass functionality is required, anexternal bypass devicemust be purchased and configured.Hardware bypass ensures network continuity in case of a firewall failure by physically rerouting traffic around the device. Since this feature is not included by default in the USG6000E-B, additional hardware is necessary to achieve it.

MACsec(Media Access Control Security) is aLayer 2 security protocolthat provides end-to-end encryption for Ethernet frames. It ensuresconfidentiality, integrity, and authenticityof data on wired networks.

A (Service data encryption):Encrypts Ethernet frames to protect against eavesdropping.

B (Data frame integrity check):Prevents data tampering and corruption.

C (Replay protection):Detects and prevents replay attacks by using unique sequence numbers.

D (Data source authenticity verification):Ensures that received data is from a legitimate source by using cryptographic authentication.

The statement is incorrect because IP addresses function at the network layer (Layer 3) of the OSI model, not the data link layer (Layer 2). At the data link layer, devices useMAC addresses(Media Access Control addresses) to identify each other. MAC addresses are unique identifiers assigned to network adapters and are defined by the IEEE 802 standard.While IP addresses are essential for routing data across networks, they are not directly related to the data link layer. Therefore, the claim that "the address that functions at the data link layer is called an IP address" is false.

Comparison of S5735-L and S5731-S Series Switches:

Both series belong to Huawei's campus switch portfolio but target different use cases and have distinct features.

Subcard Expansion Ports:

S5735-L Series:These switches donotsupport subcard expansion ports. They are designed for fixed configurations and are suitable for small to medium-sized networks.

S5731-S Series:These switchesdosupport subcard expansion ports, allowing for greater flexibility in terms of port types and densities. This makes them ideal for larger or more complex networks.

Conclusion:The statement is TRUE because the S5735-L series lacks subcard expansion ports, while the S5731-S series supports them.

Overview of Huawei Controllers:

Huawei offers a range of controllers under the iMaster NCE series, each designed for specific use cases.

Analysis of Each Controller:

iMaster NCE-Fabric:Focuses on data center network automation and management. It does not support unified LAN-WAN management.

iMaster NCE-WAN:Specializes in WAN management, particularly for SD-WAN solutions. It does not manage LANs.

iMaster NCE-Campus:Designed for campus networks, this controller supportsunified LAN-WAN management, enabling centralized control of both wired and wireless networks.

iMaster NCE-IP:Focuses on traditional IP/MPLS network management and does not support unified LAN-WAN management.

Conclusion:The correct answer is Option C, as iMaster NCE-Campus supports unified LAN-WAN management.

Geographic Redundancy in SD-WAN Controllers:

Huawei's SD-WAN solution provides geographic redundancy to ensure high availability and disaster recovery.

Analysis of Each Statement:

Option A:This is correct. The active and standby clusters share the same domain name or IP address, enabling seamless failover during an active/standby switchover.

Option B:This is correct. Geographic redundancy requires the active and standby clusters to have the same number of nodes to ensure balanced performance.

Option C:This is correct. Huawei's SD-WAN solution supports only one active cluster and one standby cluster for geographic redundancy.

Option D:This is incorrect. While the active and standby clusters synchronize data in real time, only the active cluster provides services. The standby cluster remains idle until a failover occurs.

Conclusion:The FALSE statement is Option D.

MPLS (Multiprotocol Label Switching) uses labels to forward packets efficiently along predefined paths called Label Switched Paths (LSPs). These labels are assigned dynamically using protocols likeLabel Distribution Protocol (LDP)or RSVP-TE (Resource Reservation Protocol - Traffic Engineering).While static routing and manual configuration can define paths, they do not involve dynamic label assignment.Similarly, direct routes are not related to MPLS label distribution. LDP is specifically designed to exchange label information between routers, enabling MPLS forwarding.
