Using a cell optimization tool, you detect a sector that takes a large amount of traffic from a distant location that is covered by other sites and is also outside of the coverage predicted for this sector.
Which physical optimization action should you perform first In this situation?

• A.Increase the transmit power and verify the result.
• B.Install TMA and verify the result.
• C.Increase the antenna height and verify the result.
• D.Downtilt the antenna and verify the result.

What is a benefit of Remote Radio Unit (RRU) deployment compared to a standard Radio Unit (RU) deployment?

• A.RRU provides easier deployment and maintenance.
• B.RRU has lower feeder loss.
• C.RRU consumes less power.
• D.RRU provides for easier legalization of the equipment.

In LTE, what is the definition of an A2 event?

• A.The serving cell becomes worse than the threshold.
• B.The neighbor cell becomes worse than the threshold.
• C.The neighbor cell becomes better than the threshold.
• D.The serving ceil becomes better than the threshold.

Several operators are using a Multi Operator Core Network (MOCN) with the Shared LTE RAN feature.
Which element is shared by the operators in this scenario?

• A.IMS
• B.MME
• C.eNodeB
• D.SGW

What is an advantage of using flexible numerology in New Radio (NR) 5G?

• A.It maintains a more consistent overhead over a very large range of carrier frequencies.
• B.It ensures that the same subcarrier bandwidth is used in NR in both high and low frequencies.
• C.It provides a non defined link between subcarriers used in LTE and NR.
• D.It allows an alphanumeric mapping between physical data channels on coslted LTE and NR in non-standalone scenarios.
