About

Cisco Certified Support Technician Networking (CCST Networking, exam code 100-150) is Cisco's entry-level networking certification, launched in December 2023. It validates foundational skills required for help desk technicians, network support specialists, junior network operations center (NOC) analysts, and junior network engineers working in production networks.

Market positioning: CCST Networking sits deliberately between CompTIA Network+ (vendor-neutral, broader IT context) and Cisco CCNA 200-301 (advanced, requires deeper lab experience). Unlike CCNA, which typically requires 200–300 hours of study, CCST demands 150–200 hours, making it accessible to career starters with minimal networking background. The certification directly maps to real job roles: most NOC Tier 1 technician and junior network support roles list CCST or equivalent as preferred.

Practical focus: The exam emphasizes real-world troubleshooting, command-line interface (CLI) operations, physical-layer diagnostics, and hands-on configuration of Cisco switches and routers. Performance-based lab questions simulate actual technician tasks: connecting a cable correctly, interpreting show command output, identifying a VLAN misconfiguration, or troubleshooting ping failures. This is not theoretical; CCST tests what you'll do on day one as a network support tech.

Career trajectory: CCST Networking is explicitly designed as the on-ramp to Cisco's professional track. After CCST + 3–6 months production experience, candidates pursue CCNA 200-301, then CCNP Enterprise within 1–3 years. Cisco actively markets CCST as a feeder program to CCNA, with Networking Academy integration and direct pathways in job postings.

Topics covered

The CCST Networking 100-150 exam blueprint covers practical network support skills organized around six functional domains:

  • Standards and Concepts (15–20%) — OSI model (all 7 layers), TCP/IP stack, encapsulation, protocols (TCP, UDP, ICMP), port numbers, MAC vs. IP addressing, unicast/multicast/broadcast
  • Addressing and Subnet Formats (15–20%) — IPv4 and IPv6 addressing, CIDR notation, subnetting fundamentals, address classes (legacy), DHCP operation and troubleshooting, NAT basics, private vs. public addressing
  • Endpoints and Media Types (15–20%) — Ethernet standards (802.3), cabling types (Cat5e, Cat6, Cat6A, single-mode fiber, multimode fiber), connector types (RJ45, fiber optics), wireless fundamentals (802.11a/b/g/n/ac/ax), media testing, cable termination
  • Infrastructure Components (20–25%) — Cisco device types (switches, routers, firewalls), interface types and status, VLAN creation and trunking, Spanning-Tree Protocol (STP/RSTP) concepts, static routing, basic dynamic routing (OSPF, EIGRP overview)
  • Diagnostics and Troubleshooting (15–20%) — Systematic troubleshooting methodology, ping/traceroute/ipconfig/netstat commands, show commands output interpretation, LED status lights, packet flow analysis, common network problems (wrong VLAN, duplex mismatch, bad cable)
  • Security and Network Operations (10–15%) — Access Control Lists (standard and extended), firewall basics, VPN concepts, device access (SSH vs. Telnet), physical security, CDP/LLDP protocols, syslog basics

Exam format note: The 75 questions include scenario-based labs and drag-and-drop tasks. You may be asked to configure a VLAN, troubleshoot ping failures, identify correct cabling, or interpret show command output in real time.

Typical study timeline

Full-time study (career change scenario):

  • Weeks 1–4: Network fundamentals, OSI model, TCP/IP, IP addressing (Networking Academy course)
  • Weeks 5–7: Cisco IOS CLI, VLAN configuration, switching basics (hands-on labs)
  • Weeks 8–10: Routing, troubleshooting, practice exams (Boson or Cisco Press companion)
  • Week 11: Review weak areas, take final practice tests
  • Week 12: Exam day

Part-time study (working technician, 5–8 hrs/week):

  • Months 1–2: Fundamentals (YouTube + Networking Academy modules)
  • Months 2–3: Hands-on labs (GNS3 or real Cisco equipment)
  • Months 3–4: Practice exams, review
  • Month 5: Exam

Prerequisite knowledge: CompTIA A+ or Network+ significantly accelerates this timeline (can reduce by 2–4 weeks). Candidates with zero networking background should plan 4–6 months.


Related certifications

  • Stacks with: CompTIA A+ (foundational IT); CompTIA Network+ (vendor-neutral networking)
  • Prerequisite for: Cisco CCNA 200-301 (no hard requirement, but CCST Networking recommended)

Career progression (CCST → CCNA → CCNP)

Typical timeline from CCST Networking to CCNP Enterprise (5–7 years):

MilestoneCertTimelineSalary (USD)Prerequisites
Entry supportCCST Networking (100-150)1–3 months study$40k–$55kNone
Junior engineerCCNA 200-3013–6 months after CCST$65k–$85kCCST or equivalent
Network engineerCCNP Enterprise Core (ENCOR 350-401)6–12 months on the job$95k–$130kCCNA + 3+ yrs production

Architect/senior specialistCCIE Enterprise (written + lab)24+ months intensive study$140k–$200k+CCNP + 6+ yrs; $4k–$8k exam costs

Fast-track option: Candidates with strong network operations background (e.g., NOC technicians with 2+ years hands-on experience) can sometimes skip CCST and pursue CCNA directly (6–9 months vs. 3 months), reducing total time to junior engineer role.

Industry context: Cisco CCST Networking has become the default on-ramp into enterprise networking roles since its launch in late 2023. Most corporate recruiting pipelines now see CCST → CCNA → CCNP as the standard progression, with CCNA no longer viewed as an entry cert but rather a mid-career consolidation cert. CCST adoption is accelerating globally, particularly in MSPs, ISPs, and Fortune 500 NOCs.
