Should You Certify Now or Later?
It is a question of your current timeline. If you do not have a lot of experience then the study time for CCNA is typically 3–6 months. You could study for CCNA in say two months with experience.
The new CCNA 200–301 exam is not available for registration until Feb. 24, 2020 and the earliest any study guides will be available is typically two months before that. The other consideration is that very little is often known about new certification exams and it takes around 6 months at least for an abundance of new training course, videos, books etc. to appear online. Something to consider as well is that there will only be a single exam instead of two exams so that will make it difficult as well.
CCNA 200-301 is a 120-minute exam associated with CCNA certification that replaces all current CCNA exams with only a single exam effective Feb. 24, 2020.
Current CCNA Exams
CCNA 200-125, ICND1 100-105, and ICND2 200-105 are available for registration until Feb. 23, 2020. Study for the current CCNA exam now before it expires.

10% Automation and Programmability
CCNA 200-301 exam includes a significant amount of wireless and network programmability. That is attributed to the popularity of mobile devices, cloud computing and SDN architecture. Cisco is aligning the CCNA certification exam with a shift to internet-based connectivity model and OSPF for routing IP protocol only. EIGRP was previously created for multiprotocol routing and RIP is not scalable for mobile and cloud connections.
There are significant changes in how WAN services are delivered with the advent of SD-WAN and management of network infrastructure. Newer WAN services are often based on broadband DSL and cable instead of older leased lines and Frame Relay. In addition Metro Ethernet is replacing MPLS for data center connectivity.
The management and troubleshooting of network infrastructure is being radically changed with SDN open source architecture. Cisco has enabled programmable features on their devices and virtualization from physical equipment to software services. They have virtual appliances and CCNA engineers now support private and cloud data center connections. It is helpful to know AWS routing as well considering cloud implements VRFs or multiple routing tables within a customer private network.
