質問 # 264
Which of the following commands is used to adjust the cost of an IS-IS interface?
正解：C
解説：
In Intermediate System to Intermediate System (IS-IS), the cost (metric) determines the preferred routing path. The cost is assigned to each interface, and IS-IS uses the shortest path (lowest cost) to reach a destination.
The correct command to manually modify the IS-IS interface cost is:
kotlin
CopyEdit
interface GigabitEthernet 0/0/1
isis enable 1
isis cost <value>
Where <value> represents the manually configured cost of the interface.
Incorrect Options:
* A. isis circuit-type - Used to define the circuit type (Level-1, Level-2, or both), but does not affect cost. #
* B. isis timer hello - Modifies the hello interval for IS-IS neighbors but does not change cost. #
* C. isis circuit-level - Not a valid IS-IS configuration command. #

* HCIE-Datacom Certification Guide - IS-IS Protocol Configuration
* Huawei Command Reference for IS-IS

Refer to the figure.
Which of the following steps are mandatory to enable 802.1X authentication on GE0/0/2 and GE0/0/3 of SW3 and configure a RADIUS server to authenticate and deliver network access rights to users?
正解：A、B、C、D
解説：
Understanding 802.1X Authentication in Enterprise Networks
# What is 802.1X?
* 802.1X is a network access control (NAC) protocol that enforces authentication before allowing a device to connect to a LAN.
* It uses EAP (Extensible Authentication Protocol) over RADIUS for user verification.
* Typically deployed in corporate and campus networks for secure wired and wireless access.
# How Does 802.1X Work?1## Client (Supplicant) # Requests network access.2## Switch (Authenticator) # Forwards request to RADIUS server.3## RADIUS Server # Verifies credentials & grants access.
Mandatory Steps to Enable 802.1X on SW3
# A. Configure an AAA Scheme
* Defines authentication, authorization, and accounting (AAA) methods.
* Links 802.1X authentication to the RADIUS server.
# B. Configure an Authentication Profile
* Specifies how authentication is handled on the switch.
* Associates 802.1X authentication with an AAA scheme.
# C. Configure an Authentication Domain
* Groups authentication policies for different user types.
* Maps AAA scheme to user login requests.
# D. Configure an 802.1X Access Profile
* Applies 802.1X authentication to specific switch ports (GE0/0/2 & GE0/0/3).
* Ensures that only authenticated users can pass traffic.
Why Are All Four Steps Necessary?
# Each step plays a critical role in enabling 802.1X authentication and linking it to the RADIUS server.
# Without any one of these configurations, the 802.1X authentication process would fail.
Real-World Application:
* Enterprise Wired Security: Ensures that only authenticated devices access corporate networks.
* University Campuses & Public Wi-Fi: Prevents unauthorized access to secure LAN environments.

In the following topology diagram, R1 can access the Internet through R2 and R3, R1 and R2, R1 and R1 An EGP connection is established between R3 , and R2R3 belongs to the same AS, each via BGP Publishing a default route that requires R1 to visit lnternet's traffic preference R2, can the following practices be achieved?
正解：A、C
質問 # 267
Which of the following statements about DHCP snooping isincorrect?
正解：A
解説：
Comprehensive and Detailed In-Depth Explanation:
The statementAis incorrect because enablingDHCP snooping in the VLAN viewonly takes effect on interfaces within that specific VLAN that have DHCP snooping configured. It doesnotautomatically apply to all interfaces of the device. Each interface within the VLAN must individually be configured or marked as trusted/untrusted.
B:Correct, as DHCP snooping, when enabled globally without any additional specifications, defaults to processingDHCPv4messages.
C:Correct, as DHCP snooping can protect against DHCP spoofing attacks by marking interfaces astrustedoruntrusted.
D:Correct, enabling DHCP snooping on an interface means it will monitor all DHCP messages on that specific interface.
質問 # 268
Network administrator A wants to use an IP prefix-list to match specific routes. Which of the following routes can be matched by the IP prefix-list shown in this figure?
ip ip-prefix TEST permit 10.0.0.0 24 less-equal 30
正解：C、D
解説：
Understanding Prefix Lists
* IP Prefix-Lists are used for filtering BGP routes and controlling route advertisement & redistribution.
* The command ip ip-prefix TEST permit 10.0.0.0 24 less-equal 30 means:
* Matches prefix 10.0.0.0/24 exactly.
* Matches any subnet of 10.0.0.0/24 with a prefix length between 24 and 30.
Analysis of Routes:
* # 10.0.0.0/24 # Matches exactly.
* # 10.0.0.1/30 # Falls within 10.0.0.0/24 & length #30.
* # 10.0.1.0/24 # Not within 10.0.0.0/24 range.
* # 10.0.2.0/24 # Not within 10.0.0.0/24 range.
Real-World Use Case:
* BGP route filtering: Only allows 10.0.0.0/24 and its subnets (up to /30).
* Prevents unintended route propagation in large-scale networks.
