NEW QUESTION # 34
Which of the following statements is false about GRE over IPsec?
Answer: D
Explanation:
Option B is false because it reverses the encapsulation behavior. In IPsec transport mode, the IPsec security header is inserted after the existing IP header; a new outer IP header is not normally added. In tunnel mode, the complete original IP packet is encapsulated and a new outer IP header is added. Tunnel mode therefore generally introduces greater overhead and produces a longer packet than transport mode, not the reverse.
The remaining statements are correct. IPsec supports both transport and tunnel modes. GRE over IPsec performs GRE encapsulation first, allowing GRE to transport the original payload, and then applies IPsec protection to the resulting GRE packet. The IPsec security association is established between the GRE tunnel endpoints, protecting the GRE-encapsulated traffic as it traverses an untrusted transport network.
Huawei SD-WAN data channels can use either GRE or GRE over IPsec. GRE provides flexible overlay encapsulation, while IPsec adds confidentiality, integrity, origin authentication, and anti-replay protection for site-to-site traffic. Huawei specifically identifies IPsec encryption as the mechanism securing site-to-site SD- WAN services.
NEW QUESTION # 35
Which of the following wireless security standards was proposed by China?
Answer: B
Explanation:
WAPI, or WLAN Authentication and Privacy Infrastructure, is the wireless LAN security standard proposed by China. It provides wireless link authentication and data-protection mechanisms and was developed as an alternative security framework for WLAN environments. Huawei's training material explicitly identifies WAPI as a WLAN security standard proposed in China and states that it provides stronger protection than legacy WEP and WPA mechanisms.
WPA, WPA2, and WPA3 belong to the Wi-Fi Protected Access family maintained through Wi-Fi industry certification. WPA was introduced as an interim improvement over WEP. WPA2 adopted stronger IEEE
802.11i security mechanisms, including AES-based CCMP. WPA3 later introduced stronger password- authentication and enterprise-security options.
WAPI incorporates authentication and encryption as part of an integrated wireless security architecture. Its deployment depends on regional requirements, terminal compatibility, AP support, and the organization's regulatory or cryptographic-policy obligations. The question asks which standard originated as a Chinese wireless security standard, not which standard is most widely deployed internationally. Therefore, WAPI is the only correct choice, making option B the verified answer.
NEW QUESTION # 36
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 # 37
What is the maximum number of access units supported by a central switch on a passive Ethernet network (PEN)?
Answer: A
Explanation:
A central switch in the relevant passive Ethernet network architecture supports a maximum of 48 access units.
The architecture replaces a conventional multi-layer access design with a centralized switch and distributed remote or access units. The access units function as extensions of the central switch's ports, simplifying device management, configuration, and topology maintenance.
Huawei's CloudEngine S5731-H fixed central-switch specification provides models with 24 or 48 hybrid optical-electrical downlink ports. The 48-port model can therefore directly manage up to 48 associated access or remote units under the design limits represented by this question. The same hybrid links can provide data transmission and remote PoE power, enabling access units to be installed closer to terminals without requiring conventional active aggregation equipment at every location.
The central switch automatically discovers the topology, while remote units behave as extended ports rather than independently managed switches. This reduces management nodes and simplifies a traditional three- layer network into a two-layer architecture. The larger values of 64, 72, and 96 exceed the supported maximum for the specified central-switch implementation. Therefore, option C is correct.
NEW QUESTION # 38
Which 5G-Advanced capabilities does the AR5710-S8T1XWE-NRGL support?
Answer: A,B,C,D
Explanation:
The AR5710-S8T1XWE-NRGL supports all four listed 5G-Advanced capabilities. Support for 3GPP Release
16 enables enhanced 5G New Radio functions and provides the standards foundation for improved mobile- WAN capacity, reliability, and service performance.
Carrier aggregation combines multiple component carriers to increase available throughput. Downlink 3CC allows three component carriers to be aggregated for received traffic, while uplink 2CC combines two carriers for transmitted traffic. This is valuable for high-bandwidth branch access, video backhaul, and mobile private- network scenarios.
Support for eight APNs permits multiple logically separated mobile services or provider profiles to be configured. Different APNs can represent enterprise services, management traffic, production systems, backup connectivity, or isolated customer networks. Global-frequency-band support improves deployment flexibility across countries and carrier networks, subject to local spectrum regulation and the supported modem variant.
Huawei SD-WAN can use 5G as a primary, secondary, or bypass link and supports combinations such as dual
5G and 5G plus wired connectivity for service assurance. Therefore, NR Release 16, carrier aggregation, eight APNs, and global frequency bands are all supported.
