Sample Questions from Cisco Certified Network Associate - CCNA (200-301)

Preview a few questions below — answers are revealed when you take the exam.

1. A team needs to configure a new network segment that requires high availability and load balancing for web traffic. What approach should they take to ensure optimal performance and redundancy?

   • Implement a single high-capacity server with advanced caching mechanisms to handle all web traffic.
   • Deploy a cluster of web servers behind a load balancer, configure health checks, and use redundant network paths.
   • Use a content delivery network (CDN) exclusively to manage all web traffic without local servers.
   • Set up a single firewall with deep packet inspection to manage and balance all incoming web traffic.

2. Consider the situation where a company is merging two networks with different addressing schemes. Which method solves it best to avoid IP address conflicts and ensure seamless communication?

   • Reassign all IP addresses in one network to match the other network's scheme manually.
   • Implement Network Address Translation (NAT) at the border routers to translate addresses between the two networks.
   • Use a third-party DNS service to resolve IP conflicts dynamically as they occur.
   • Deploy a new subnet for all merged network devices and reassign IP addresses network-wide.

3. Which option best evaluates the effectiveness of a network's security posture after implementing new firewall rules?

   • Conduct regular user surveys to gauge perceived security improvements.
   • Perform a penetration test to identify vulnerabilities and assess the impact of the new rules.
   • Review firewall logs for a decrease in blocked traffic as an indicator of improved security.
   • Increase the frequency of security awareness training sessions for employees.

4. How should a professional assess the impact of implementing Quality of Service (QoS) on a congested network?

   • Monitor network performance metrics before and after QoS implementation to evaluate changes in latency and throughput.
   • Survey end-users for their subjective experience of network performance improvements.
   • Analyze the CPU usage of network devices to determine if QoS has increased processing load.
   • Check for any new hardware failures post-implementation as a sign of QoS impact.

5. What strategy should be applied when designing a wireless network to ensure coverage in a large, multi-floor building?

   • Place a single high-power access point in the center of the building to cover all floors.
   • Deploy multiple access points on each floor, ensuring overlap to prevent dead zones and using a wireless controller for management.
   • Use directional antennas on all access points to focus the signal towards specific areas of each floor.
   • Rely solely on client device signal strength to adjust coverage areas dynamically.
