Cisco Certified Technician Routing & Switching (RSTECH) Free Practice Test — 30 Questions

Question 1

Anya, a network technician at a mid-sized enterprise, is troubleshooting intermittent connectivity and fluctuating latency impacting VoIP calls at a remote branch office. Initial checks of the physical layer, including cable integrity and transceiver diagnostics, revealed no obvious faults. Subsequent investigation into interface error counters at the data link layer also yielded no significant anomalies. Anya then verified routing table accuracy and confirmed the absence of routing loops at the network layer. Despite these efforts, the problem persists, suggesting a more complex underlying cause that is not immediately apparent from standard layer-by-layer checks.

What is the most critical next diagnostic step Anya should undertake to effectively isolate the root cause of the persistent connectivity issues?

Accepted Answer

Analyze the router's CPU and memory utilization for signs of overload or performance degradation.

Question 2

Anya, a network technician, is alerted to a complete network failure affecting a major financial institution\'s trading platform precisely at the market open. The established incident response plan is proving insufficient due to the unprecedented nature of the fault, which appears to stem from a cascading failure initiated by a recently deployed firmware update on a core router. Clients are experiencing significant financial losses, and senior management is demanding immediate updates. Anya must simultaneously troubleshoot the technical issue, manage external communications, and coordinate her junior team members who are also under immense pressure. Which behavioral competency is most critically demonstrated by Anya\'s actions in this high-stakes, time-sensitive situation?

Accepted Answer

Accepted Answer

Adaptability and Flexibility

Question 10

Anya, a network technician, is overseeing a critical upgrade of a core routing device. Midway through the planned maintenance window, a complete network connectivity failure occurs across the entire enterprise. The upgrade process has stalled, and initial diagnostic checks suggest an unexpected interaction between the new firmware and a legacy access control list (ACL) that was not flagged in pre-upgrade testing. The SLA mandates a full restoration of services within 30 minutes of the outage\'s commencement. Anya has a limited window to resolve the issue before the maintenance period ends and the network is required to be fully operational for business hours. Which of the following immediate actions best exemplifies the necessary behavioral competencies to address this crisis effectively?

Accepted Answer

Systematically analyze the ACL configuration and its interaction with the new firmware, potentially rolling back the ACL or firmware to a known stable state to restore connectivity.

Question 11

Anya, a network technician responsible for maintaining a critical enterprise network, was scheduled to perform a routine firmware upgrade on Router-A, a key device in the network\'s backbone. Mid-way through her preparation, an alert indicates a catastrophic hardware failure on Router-B, another critical router that handles a significant portion of inter-VLAN traffic. This failure has caused widespread connectivity issues for several departments. Anya\'s original task of upgrading Router-A is now secondary to restoring network functionality. She quickly devises a temporary solution by reconfiguring a series of edge switches to reroute traffic through an auxiliary, lower-bandwidth path, mitigating the immediate outage while she coordinates with the hardware vendor for Router-B replacement. Which of Anya\'s behavioral competencies is most prominently demonstrated in this situation?

Anya, a network technician, is overseeing a scheduled maintenance window for a critical enterprise network. Midway through the planned configuration updates, a widespread routing loop is detected, causing significant customer service disruption. Anya immediately consults the network topology diagrams and verifies the status of affected router interfaces. While a full rollback to the pre-maintenance state is a possibility, Anya suspects the loop is directly related to the specific routing protocol adjustments made moments before the outage. Considering the need to restore service swiftly but also to prevent future occurrences, which course of action best exemplifies effective problem-solving and adaptability in this high-pressure situation?

Accepted Answer

Analyze the specific routing protocol configuration changes implemented during the maintenance, cross-reference with vendor documentation for potential loop-inducing scenarios, and implement a precise correction to the configuration to resolve the loop.

Question 13

Anya, a network technician, is troubleshooting intermittent packet loss affecting VoIP quality on a Cisco ISR router segment. While interface error counters show minimal issues, `ping` tests reveal sporadic packet drops. She suspects a misconfiguration related to traffic management. Which of the following Cisco IOS configuration elements, if improperly applied, is most likely to cause such symptoms without saturating the link or showing significant interface errors?

Accepted Answer

An incorrectly defined `class-map` or an overly restrictive `police` action within a `policy-map` applied to the interface.

Question 14

Anya, a network technician tasked with a critical infrastructure upgrade for a high-frequency trading firm, faces a significant roadblock. The planned implementation of advanced routing protocols, intended to enhance network performance and meet strict financial regulatory mandates like SOX compliance for data integrity, is jeopardized by an unforeseen hardware incompatibility discovered during late-stage testing. The legacy switch, critical for segmenting a key trading floor network, refuses to establish stable adjacencies with the new core routers. This discovery requires an immediate shift from the meticulously planned deployment schedule, potentially impacting operational continuity and client trust. Anya must quickly assess the situation, formulate an alternative technical approach that still satisfies the regulatory requirements and performance benchmarks, and communicate the revised plan to her project manager and the client. Which primary behavioral competency is Anya demonstrating by effectively navigating this critical juncture and ensuring the project\'s continued progress despite the unexpected technical impediment?

Accepted Answer
