Conclusion:The statement is FALSE because the CloudEngine 6881 supports M-LAG.

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.

The main control boards work in 1:1 backup mode. When a main control board is removed and then installed, no packet loss occurs and the performance does not deteriorate : The S8700 ensures high availability through redundant main control boards. This feature guarantees uninterrupted operation even during maintenance or failures.

All four options accurately describe the hardware characteristics of the S8700, making them all correct.

iMaster NCE (Network Cloud Engine) uses NETCONF (Network Configuration Protocol) to deliver configurations to network devices. NETCONF is an XML-based protocol that provides a standardized way to configure and manage network devices programmatically.

Telemetry : Used for collecting operational data from devices, not for configuration delivery.

SDN : Refers to a broader concept of software-defined networking, not a specific protocol.

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

Adefault routeis a special type of route used in routing tables to forward packets when no specific route matches the destination IP address. It acts as a "catch-all" route for traffic that does not match any other routes in the routing table.The default route is typically represented as0.0.0.0/0, where:

0.0.0.0represents any destination IP address.

/0indicates a subnet mask of 0 bits, meaning it applies to all possible IP addresses.

Default routes are commonly used in scenarios where a router needs to forward traffic to a gatewayor next-hop device for further processing. This simplifies routing table management, especially in networks with limited or centralized connectivity.

Remote Office Requirements:

Remote office solutions enable secure access to corporate resources for employees working outside the office.

Firewall Functions for Remote Access:

SSL VPN:Provides secure remote access over HTTPS, allowing users to connect to internal applications without requiring additional client software.

IPS (Intrusion Prevention System):Protects against network attacks but does not provide remote access.

AntiVirus:Focuses on detecting and blocking malware, not remote access.

IPsecVPN:While IPsecVPN can provide remote access, it typically requires more complex configurations compared to SSL VPN.

Conclusion:The correct answer is Option A, as SSL VPN is the most user-friendly and widely used function for remote office requirements.

A Wide Area Network (WAN) is designed to span large geographical areas, such as cities, regions, or even countries. WANs enable long-distance communication and are typically used to connect multiple Local Area Networks (LANs) or Metropolitan Area Networks (MANs). They rely on technologies like MPLS, SD-WAN, and leased lines to provide connectivity over vast distances.

The description provided in the question accurately reflects the characteristics and purpose of a WAN. Therefore, the statement is TRUE .

Huawei'sdata center autonomous driving networkis classified asL3: conditional autonomous network.

Command line injection:Attackers inject malicious commands into input fields, compromising system integrity.

Brute-force attacks:Attackers attempt to guess passwords or encryption keys through repeated trial-and-error attempts.

These attack methods highlight the importance of implementing robust security measures, such asfirewalls, intrusion detection/prevention systems, and regular patching.

In IP-based networks, routers use the destination IP address in the network layer header to determine the next hop for forwarding packets. The routing table contains entries that map destination IP addresses to outgoing interfaces or next-hop routers.

Source MAC and Destination MAC are Layer 2 (data link layer) addresses and are not used for routing decisions.

Source IP is irrelevant for routing, as the router focuses on delivering the packet to the destination IP address.

Thus, the correct answer is B , as routers use the destination IP address to make forwarding decisions.

Managing a large number of branches in an enterprise WAN environment presents several challenges. Below is an analysis of each option:

Difficulties in rectifying faults on branch networks : With numerous branches, identifying and resolving network faults becomes complex, especially when relying on manual troubleshooting.
