We study the embedded topology of certain conic-line arrangements of degree 7. Two new examples of Zariski pairs are given. Furthermore, we determine the number of connected components of the realization spaces of the conic-line arrangements with prescribed combinatorics. We also calculate the fundamental groups using SageMath and the package Sirocco in the appendix.
