What is the primary advantage of implementing a queue using a linked list?

Dynamic memory allocation
Fixed size
Easier to implement
Faster access time

Which pointer is updated when a new element is enqueued in a linked list implementation of a queue?

Front pointer
Rear pointer
Both front and rear pointers
None of the above

What happens when you dequeue an element from an empty queue implemented using a linked list?

The program crashes
An underflow condition occurs
The front pointer is set to null
A new node is created

What is the time complexity of enqueue and dequeue operations in a queue implemented using a linked list?

O(1)
O(n)
O(log n)
O(n²)

Which of the following is true about a queue implemented using a linked list?

It requires a fixed amount of memory
It can grow or shrink dynamically
It does not require pointers
