Cisco Certified Technician Routing & Switching (RSTECH): Exam Scope, Retirement Status, and Preparation Decisions
The Cisco Certified Technician Routing & Switching (CCT Routing & Switching) certification validated practical onsite support and maintenance skills for Cisco routers, switches, and their operating environments. Its associated exam, Supporting Cisco Routing and Switching Network Devices (100-490 RSTECH), covered networking fundamentals, Cisco hardware, IOS operation, and service tasks. This guide helps you make the most important decision first: whether you are researching the former RSTECH exam or need to prepare for its replacement, 800-150 FLDTEC, because RSTECH is no longer available for testing.
Can you still take the 100-490 RSTECH exam?
No. Cisco lists 100-490 RSTECH as a retired exam, and the last date to test was February 9, 2025. Cisco states that retired exams are no longer available for certification or recertification. Candidates seeking a current CCT field-technician route should review the replacement exam rather than schedule study around RSTECH.
The relevant replacement listed by Cisco is Supporting Cisco Devices for Field Technicians (800-150 FLDTEC). Cisco describes the updated CCT Field Technician program as a merger of the former CCT Collaboration, CCT Data Center, and CCT Routing and Switching certifications. This changes the preparation decision: use RSTECH material for historical scope or transferable fundamentals, but verify the current exam requirements before registering.
Existing holders should separate certification validity from exam availability. Cisco says active certifications based on retired exams remain valid until their individual expiration dates, but the retired exam cannot be used for certification or recertification. Check Cisco’s current certification records and retirement information for your own status.
What did RSTECH validate?
RSTECH was designed for practical support work rather than only abstract networking theory. The CCT Routing & Switching certification focused on onsite support and maintenance of Cisco routers, switches, and operating environments. A strong preparation plan therefore connected terminology to physical identification, IOS access, backup work, replacement procedures, and basic fault isolation.
The official blueprint grouped the exam into general networking knowledge, Cisco equipment and related hardware, Cisco IOS software operation, and service-related knowledge. These are useful study categories even though the exam itself is retired, because they describe the field-technician task pattern: understand the network, identify the device, use the operating environment, and carry out service work safely.
The associated Cisco course had no prerequisite. That does not mean every candidate could begin effectively without background knowledge. You should be able to recognize basic network components, follow an IP-addressing explanation, and work carefully with device interfaces before spending most of your time on IOS procedures.
Which networking topics belong in the foundation?
The general networking section covered the OSI and TCP/IP models, switches, routers, wireless access points, Layer 2 technologies, cabling, IPv4 and IPv6 addressing, FTP, TFTP, PING, Telnet, and SSH. Study these as connected troubleshooting concepts: identify the layer, identify the medium or protocol, then determine what evidence would confirm or reject a suspected fault.
Build a one-page reference sheet in your own words. Put the OSI and TCP/IP models beside examples of physical links, switching behavior, addressing, and management access. Add a short distinction between FTP and TFTP, and between Telnet and SSH. The purpose is not memorization for its own sake; it is to recognize what a technician can test and what each tool or protocol is used for.
Cabling deserves practical attention. Review connection types, interface purposes, and the consequences of using an unsuitable cable or transceiver. When studying a troubleshooting scenario, ask whether the failure could be physical before assuming an addressing or IOS problem. That sequence reflects the basic Layer 1 and Layer 2 troubleshooting emphasis in the course objectives.
What Cisco hardware identification should you practise?
The equipment section required identification of Cisco products, product markings and model numbers, transceiver modules, and product serial-number locations. Prepare to extract information from labels and hardware views, not merely recognize a product family name. A field technician must connect the visible device and its markings to the correct service action.
Use available, legitimate Cisco product documentation or lab equipment to practise a repeatable inspection routine. Start with the product identity, then locate interfaces, removable modules, power-related components, markings, and serial-number information. Record what you found and what remains uncertain. This builds the careful observation habit that hardware-identification questions are intended to assess.
Do not turn hardware study into an attempt to memorize every Cisco model. Prioritize the identification concepts named in the blueprint and course: models, accessories, cabling, interfaces, transceiver modules, and serial-number locations. If a detail is not supported by your official study material, treat it as a documentation lookup topic rather than inventing a rule.
How much IOS and CLI work is relevant?
The associated course trained learners to understand Cisco IOS operating modes and use the Cisco CLI to connect to and service products. Your preparation should therefore explain how access context affects the task, how to move through the CLI safely, and how to distinguish observation from configuration. Practise reading output before attempting a change.
Create short, controlled exercises around device access and service workflow. Identify the connection method, establish a terminal session, recognize the IOS mode, inspect the current state, and document the result. Only then move to a backup, restoration, upgrade, downgrade, or troubleshooting action in a suitable lab or approved environment.
A common mistake is treating CLI familiarity as proof of operational competence. A technician also needs change discipline: confirm the target device, preserve the current configuration, verify compatibility and recovery options, and record the outcome. These habits are practical recommendations, not additional Cisco exam requirements.
Which service procedures should receive the most practice?
The course objectives included hardware break/fix, software and configuration backup and restoration, software upgrades and downgrades, connection-type and cable recognition, and basic Layer 1 and Layer 2 troubleshooting. Organize study around those procedures in a logical service sequence instead of reading each topic as an isolated definition.
For hardware work, practise identifying the suspected component and checking the physical path before replacement. For configuration work, learn the purpose of creating a recoverable backup and the checks that follow restoration. For software changes, study why version selection, access, backup, and rollback planning matter. Use official documentation for platform-specific commands rather than relying on unofficial command lists.
The course also referenced Tera Term, PuTTY, TFTP and FTP servers, USB storage, a loopback plug, and Windows for basic Cisco software configuration and tools. Treat these as tools to understand in context: know what connection or transfer problem each can help investigate, and what evidence you should verify after using it.
How should you build a practical study sequence?
Use a layered sequence: networking foundation first, hardware recognition second, IOS access third, service procedures fourth, and mixed troubleshooting last. This order prevents a common failure mode in which a candidate memorizes commands without knowing whether the suspected problem is cabling, interface hardware, Layer 2 behavior, addressing, or management access.
A workable roadmap begins with a scope audit. Read the official RSTECH topics and mark each item as familiar, partly familiar, or unknown. Next, study the general networking categories and produce your own explanations. Then use product documentation or a lab to inspect hardware and interfaces. After that, practise IOS operating modes and safe observation tasks before attempting service workflows.
Finish with scenario-based review. For each scenario, write the symptom, the most likely layer or component, the first safe check, the tool or information required, and the verification step. This is a better use of time than repeatedly rereading a topic list because it tests the decision process behind field support.
A focused final review
In the final review, revisit only weak areas identified by your notes. Check that you can distinguish network models, addressing, cabling, management protocols, hardware markings, IOS modes, backup and restoration concepts, and basic Layer 1 and Layer 2 isolation. Avoid adding large amounts of unfamiliar material at the last moment.
What should you do if you only have RSTECH study material?
RSTECH material remains useful for foundational networking, Cisco hardware recognition, IOS concepts, and service thinking, but it does not establish eligibility for a current exam. Use it to build transferable knowledge, then compare its coverage with the official 800-150 FLDTEC information before choosing a preparation path.
Cisco says the FLDTEC learning path replaced the previous RSTECH training. The updated program adds coverage associated with the merged field-technician certification, including unified computing system information, hardware identification, cabling, configuration backup and restoration, and software upgrades and downgrades. Confirm the current learning path and exam details directly with Cisco because certification information can change.
Do not assume that an old practice set, unofficial question bank, or exam dump reflects a live blueprint. Such material can contain obsolete or inaccurate content, and memorizing it cannot substitute for understanding device support. Use official Cisco topics and course information as the boundary for factual study decisions.
What were the documented exam delivery details?
For historical reference, the 100-490 RSTECH exam was closed book, did not allow outside reference materials, lasted 90 minutes, and used a format of 60–70 questions. These details applied to the retired RSTECH exam and should not be transferred to 800-150 FLDTEC without confirmation from Cisco.
The exam’s closed-book condition makes retrieval practice more useful than studying with constant reference material. After learning a concept, close the notes and explain the purpose of the protocol, component, IOS mode, or service step from memory. Then check the official material and correct the gaps.
Because RSTECH is retired, these delivery details should guide historical understanding only. If your actual goal is the current CCT Field Technician certification, use Cisco’s current exam page and registration information for delivery method, timing, question format, language, and other scheduling details.
Which preparation mistakes create the most risk?
The largest mistake is planning to sit RSTECH after its retirement. The next is studying only command syntax while neglecting hardware identification, cabling, models, protocols, and basic fault isolation. A third is confusing a course completion plan with an exam registration plan. Resolve exam status first, then choose materials that match the current target.
Another mistake is practising destructive changes without a recovery plan. Keep lab work isolated from production equipment, preserve configurations before changes, and verify the device and interface before acting. When documentation is platform-specific, consult the relevant Cisco source rather than generalizing from another model.
Finally, avoid treating percentages or unofficial topic rankings as a substitute for the blueprint. The supplied official RSTECH research identifies domains and topics but does not provide domain weight percentages here. Study all named domains, allocate extra time according to your own diagnostic results, and label that allocation as a personal recommendation rather than an official weighting.
What are the next actions for a candidate today?
First, decide whether you need historical RSTECH knowledge or the current CCT Field Technician certification. If you need a current credential, open Cisco’s retired-exam information and the official replacement-exam resources before buying study material. If you are learning field support fundamentals, use the RSTECH blueprint as a structured skills checklist.
Second, complete a short self-assessment covering networking models, IPv4 and IPv6 addressing, Layer 2 concepts, cabling, Cisco product identification, transceivers, IOS modes, CLI access, backup and restoration, software changes, and basic Layer 1 and Layer 2 troubleshooting. Mark each area by confidence and evidence, such as a completed lab or a clear written explanation.
Third, schedule study around evidence rather than a fixed number of hours. Read the official scope, practise the weakest task in a safe environment, document what you observed, and retest yourself without notes. Before registering for any replacement exam, confirm its current code, blueprint, eligibility, delivery details, and recertification rules on Cisco’s official site.
Conclusion
RSTECH is now a retired Cisco exam, so it is not a current scheduling target. Its scope still provides a useful foundation for understanding field-technician work: networking fundamentals, Cisco hardware identification, IOS and CLI operation, service procedures, and basic Layer 1 and Layer 2 troubleshooting. Use those topics to assess and strengthen your skills, then move to Cisco’s current 800-150 FLDTEC information if you need an available CCT pathway. Keep retirement status and replacement requirements separate from historical exam preparation.
