NEW QUESTION # 40
Which of the following statements is true about an AP's transmit power?
Answer: A
Explanation:
An AP's transmit power must be maintained within an appropriate range. Excessive power does not automatically improve service quality. A high-power AP can enlarge its interference domain, create co- channel or adjacent-channel interference, produce asymmetric uplink and downlink coverage, and cause sticky-client behavior because a station continues hearing an AP even when its weaker transmission cannot reliably reach that AP. Huawei states that high-power APs can interfere with adjacent APs and that radio calibration dynamically adjusts AP channels, power, and frequency bands to ensure coverage while minimizing interference.
Conversely, power that is too low creates coverage holes, weak received signal strength, low modulation rates, retransmissions, and roaming instability. When a new AP is added, neighboring APs may reduce their transmit power to limit interference. When an AP goes offline, neighboring APs may increase power to compensate for the missing coverage. The engineering objective is therefore neither maximum nor minimum power, but sufficient coverage with controlled overlap and minimum interference. Accordingly, option B is correct.
NEW QUESTION # 41
A label stack is an ordered set of labels. MPLS supports a maximum of three layers of nested labels.
Answer: B
Explanation:
The statement is false. An MPLS label stack is an ordered sequence of label-stack entries, with the top label processed first and the bottom identified by the Bottom-of-Stack bit. However, the MPLS architecture does not define a universal maximum of three nested labels. An MPLS forwarding operation may replace the top label, remove it, or push one or more additional labels onto the stack.
Practical label depth is constrained by device implementation, forwarding ASIC capabilities, packet size, and the number of network functions being encoded. A conventional MPLS VPN may use two labels: a transport label and a VPN label. More advanced deployments can add labels for traffic engineering, segment routing, entropy, service chaining, or hierarchical transport. This can produce stacks deeper than three entries.
Therefore, "three layers" may describe a limitation of a particular platform, software version, or deployment design, but it is not an MPLS protocol maximum. RFC 3032 defines the stack as a sequence of four-byte entries and explicitly allows one or more entries to be pushed without specifying a three-label ceiling.
NEW QUESTION # 42
Which of the following statements is true about MACsec?
Answer: C
NEW QUESTION # 43
Which of the following are common terminal identification methods?
Answer: A,B,C,D
Explanation:
All four options are recognized terminal identification methods. MAC OUI examines the first three bytes of a device's MAC address to determine its manufacturer, although it generally cannot identify the exact model or operating system. DHCP option identification analyzes fields such as DHCP options 12, 55, and 60, which can reveal the hostname, parameter-request list, vendor class, and other terminal characteristics. SNMP query is an active identification method that retrieves device details from relevant MIB objects and is particularly useful for printers, network devices, and other SNMP-capable equipment.
Nmap is also an active scanning method. It analyzes open ports, service responses, protocol behavior, and operating-system fingerprints to estimate a terminal's device type and OS. Huawei distinguishes information- reporting methods from proactive scanning methods: MAC OUI and DHCP options generally use information observed in traffic, whereas SNMP and Nmap actively query or scan the endpoint. iMaster NCE-Campus can correlate multiple fingerprints to improve identification accuracy and automatically apply terminal-specific access policies.
NEW QUESTION # 44
Which of the following statements are true about predefined security zones on a firewall?
Answer: A,B,D
Explanation:
Huawei firewalls provide four commonly predefined security zones: Local, Trust, DMZ, and Untrust. The Local zone represents the firewall itself, including traffic generated by or destined for the device, and has the highest default security priority of 100. The Trust zone normally represents an organization's protected internal network and has a default priority of 85, not 95. Therefore, option C is false.
The DMZ typically hosts public-facing or semi-trusted resources, such as web, email, and application servers.
Its default priority is 50, placing it between the trusted internal network and the external untrusted network.
The Untrust zone normally represents the Internet or another uncontrolled network and has the lowest predefined priority of 5.
Zone priority expresses the relative security level used to classify inbound and outbound traffic direction; it does not independently permit traffic. Security policies still determine whether matched traffic is allowed or denied. Huawei's SD-WAN design uses Trust and Untrust zones on CPEs, and iMaster NCE can orchestrate the corresponding zones and firewall policies for Internet-access protection.
