The correct answer is B .
The connection from TraceSynthesis to NetAct is typically based on secure web/API communication, which uses HTTPS . The standard HTTPS port is 443 . Therefore, port 443 must be opened in NetAct/firewall rules to allow TraceSynthesis to communicate with NetAct.
The other options are not the best answer:
8443 is often used as an alternative HTTPS/application-server port, but it is not the standard answer here.
22 is used for SSH, mainly for secure shell access or file transfer.
8080 is commonly used for unsecured HTTP or proxy/application access, not the secure NetAct connection expected here.
So the required port is:
443.

The correct answer is C .
In a Concurrent mMIMO B41/n41 AEHC 64T64R deployment, LTE and NR share the same Massive MIMO active antenna system. Public Nokia material identifies AEHC as an AirScale Massive MIMO
64T64R B41 radio product, and Nokia's AirScale Massive MIMO portfolio is designed for high-capacity 5G
/RAN deployments.
Unlike a passive antenna system where coverage is changed mainly by physical/electrical RET, Massive MIMO coverage is strongly influenced by beamforming profiles and beamforming weight parameters . In concurrent LTE/NR operation, the RF design must consider the shared active antenna behavior, not independent passive RET-style tilt control per technology.
Therefore, for concurrent 4G/5G mMIMO coverage adjustment, the correct statement is:
The tilt/coverage behavior for both 4G and 5G is controlled by mMIMOSecSectorBFProfName and beamforming weight profile parameters.

The correct answer is B .
In 5G NSA EN-DC , the UE connects to LTE as the Master Cell Group , or anchor, and NR as the Secondary Cell Group . Not every LTE band can be paired with every NR band. The supported LTE-NR combinations are defined by 3GPP band-combination rules and must also be supported by the UE chipset and device capability.
For example, an operator may have LTE Band 3, Band 7, or Band 20 and NR n78, but only certain LTE-NR combinations may be valid for EN-DC. If the selected LTE anchor band is not supported in combination with the NR band, the UE will not be able to establish EN-DC even if LTE and NR coverage both exist.
Option C is not correct because dual-uplink support depends on UE capability and specific band-combination support; it cannot be guaranteed for all UE models. Option A and D are unrelated to the main purpose of checking 3GPP band combinations.
So the correct reason is:
To ensure that LTE and NR bands are compatible and allowed as EN-DC pairs.

The correct answer is C: A, B, C, and D .
This question is about Vo5G / VoNR IMS service support in 5G SA. For IMS-based services over 5G, different QoS flows are used for signaling, voice media, and video media.
Statement A is correct.
The feature supports IMS voice and video over 5G in the gNB for FR1 , including both TDD and FDD deployments.
Statement B is correct.
IMS signaling commonly uses 5QI 5 . This QoS flow carries SIP/IMS signaling messages such as registration, session setup, modification, and release.
Statement C is correct.
IMS conversational voice uses 5QI 1 , which is the standardized GBR QoS identifier for conversational voice.
Statement D is correct.
IMS conversational video commonly uses 5QI 2 , which is associated with conversational video traffic.
