Question: What is the valid range for the PhysCellId, which identifies the physical layer identity of a cell in an E-UTRA network?
Option 1: INTEGER (1..255)
Option 2: INTEGER (0..503)
Option 3: INTEGER (100..600)
Option 4: INTEGER (500..1000)
Explanation: The correct answer, Option 2, specifies the valid range for PhysCellId as INTEGER (0..503), which aligns with the definition provided in the context of E-UTRA's physical layer identity. This range is crucial for accurately identifying cells within the network, ensuring proper communication and resource allocation. Incorrect ranges could lead to misidentification or conflicts among cell identities.
