Spark Trader Limited reports:
As we all know, communication technology engineers need to pass the professional level examination of communication professional technicians and obtain the professional level certificate of communication professional technicians. The certificate is divided into three levels: primary, intermediate and advanced. It is the best way for communication technology engineers to improve themselves by constantly obtaining higher-level certificates and accepting higher-level professional level recognition.
What do you need to master from primary to intermediate
