TRUE

FALSE

NO.28 The difference between DoS attacks and DDoS attacks is that DoS attacks are usually directly initiated by attackers, whereas DDoS attacks are usually initiated by attackers controlling multiple zombies.

TRUE

FALSE

NO.29 In SSL VPN, the firewall performs access authorization and control based on which of the following dimensions?

Role

MAC address

Port number

IP address

NO.30 Authentication rules configured on iMaster NCE-Campus support multiple matching conditions, such as matching account information, SSID information, and terminal IP address ranges, so that different authentication rules can be executed for different users.

TRUE

FALSE

NO.31 IPsec VPN does not support encapsulation of non-IP unicast packets.

TRUE

FALSE

NO.32 Which of the following statements are true about SYN scanning attacks?(Select All that Apply)

When the scanner sends a SYN packet, an RST response indicates a closed port.

If the peer end does not respond to the SYN packet sent by the scanner, the peer host does not exist, or filtering is performed on the network or host.

When the scanner sends a SYN packet, if the peer end responds with a SYN-ACK packet, the scanner then responds with an ACK packet to complete the three-way handshake.

When the scanner sends a SYN packet, a SYN-ACK response indicates an open port.

NO.33 Which of the following statements is false about the restrictions on configuring bandwidth profiles in parent and child policies on a firewall?

The connection limit specified in a child policy cannot be smaller than that specified in the parent policy.

Both the parent and child policies must both use the same traffic limiting mode; that is, either “setting the upstream and downstream bandwidths” or “setting the overall bandwidth”.

The parent and child policies must reference different bandwidth profiles.

The maximum bandwidth specified in a child policy cannot be greater than that specified in the parent policy.

NO.34 Predefined URL categories on Huawei firewalls reside in the URL category database delivered with the device and do not need to be manually loaded.

TRUE

FALSE

NO.35 Which of the following statements is false about Eth-Trunk?(Select All that Apply)

An Eth-Trunk must have at least two member links.

An Eth-Trunk must have at least one active link.

An Eth-Trunk interface is a logical interface.

An Eth-Trunk interface can be a Layer 2 or Layer 3 interface.

NO.36 SYN scanning requires a fully established TCP connection and is recorded in system logs.

TRUE

FALSE

NO.37 When an IPsec VPN is established in aggressive mode, AH+ESP can be used to encapsulate packets in NAT traversal scenarios.

TRUE

FALSE

NO.38 In the figure, if 802.1X authentication is used for wired users on the network, the network admission device and terminals must be connected through a Layer 2 network.

Options:

TRUE

FALSE

Understanding 802.1X Authentication in Wired Networks:
* 802.1X is a port-based network access control (PNAC) protocolthat requires aLayer 2 connection between thesupplicant (PC), the authenticator (switch), and the authentication server (e.g., RADIUS server).
* In wired networks,802.1X authentication occurs at the Ethernet switch (Layer 2 device), which enforces authenticationbefore allowing network access.
Why Must the Network Be Layer 2?
* 802.1X authentication operates at Layer 2 (Data Link Layer) before any IP-based communication (Layer 3) occurs.
* If the authentication device and user terminal were on different Layer 3 networks, the authentication packets (EAPOL – Extensible Authentication Protocol Over LAN)would not be forwarded.
* In the figure, the authentication control point is at theaggregation switch, which means thePC and switch must be in the same Layer 2 domain.
Components of 802.1X Authentication in the Figure:
* Supplicant (PC)# The device requesting network access.
* Authenticator (Aggregation Switch)# The switch controlling access to the network based on authentication results.
* Authentication Server (iMaster NCE-Campus & AD Server)# Verifies user credentials and grants or denies access.
* Layer 2 Connectivity Requirement# ThePC must be in the same Layer 2 networkas the Authenticatorto communicate via EAPOL.
Why “TRUE” is the Correct answer:
* 802.1X authentication is performed before IP addresses are assigned, meaning it can only operate in a Layer 2 network.
* EAPOL (Extensible Authentication Protocol Over LAN) messages are not routableand must stay within a single Layer 2 broadcast domain.
* In enterprise networks,VLAN-based 802.1X authentication is often used, where authenticated users are assigned to a specific VLAN.

* IEEE 802.1X Standard Documentation# Layer 2 Network Authentication

NO.39 HWTACACS is a centralized information exchange protocol based on the client/server structure. It uses UDP for transmission and performs authentication, authorization, and accounting for users accessing the Internet through Point-to-Point Protocol (PPP) or Virtual Private Dial-up Network (VPDN) and administrative users logging in to devices.

TRUE

FALSE

NO.40 When gateways are connected using GRE over IPsec, the IPsec encapsulation mode must be tunnel mode.

TRUE

FALSE

NO.41 If data filtering is configured on the firewall but is not correctly referenced in the security policy, the data that should be blocked can still be transmitted normally.

TRUE

FALSE

NO.42 In the figure, enterprise A and enterprise B need to communicate securely, and an IPsec tunnel is established between firewall A and firewall B. Which of the following security protocols and encapsulation modes can meet the requirements of this scenario?

AH+ESP; transport mode

ESP; tunnel mode

ESP; transport mode

AH; tunnel mode

NO.43 iMaster NCE-Campus has a built-in LDAP module that enables it to function as an LDAP server to interconnect with access devices through LDAP.

TRUE

FALSE

NO.44 Which of the following statements is false about health check?

Health check supports DNS detection protocols.

In addition to link connectivity detection, health check can also detect the delay, jitter, and packet loss rate of links in real time.

The health check function cannot be used together with PBR.

Firewalls can detect network connectivity in real time based on the health check result.

NO.45 Which of the following conditions can be matched by PBR?(Select All that Apply)

Source IP address

Source security zone

Source MAC address

Application

NO.46 Which of the following statements is false about HTTP behavior?

When the size of the uploaded or downloaded file or the size of the content obtained through the POST operation reaches the block threshold, the system blocks the uploaded or downloaded file or POST operation.

When the size of the uploaded or downloaded file or the size of the content obtained through the POST operation reaches the alarm threshold, the system generates a log to notify the device administrator and block the behavior.

You can set an alarm threshold and a block threshold to limit the size of the upload file if file upload is allowed.

The POST method of HTTP is commonly used to send information to the server through web pages.For example, use this method when you post threads, submit forms, and use your username and password to log in to a specific system.
