Sample Questions — Cisco CCNA (200-301)
5 free sample questions from this practice exam. Correct answers are highlighted.
1. A network engineer configuring a legacy 10BASE-T Ethernet segment notes that the connected devices experience frequent collisions. The engineer explains to the team how CSMA/CD handles this situation. Which of the following BEST describes the CSMA/CD collision recovery process?
2. A company is deploying IP phones throughout its campus and needs to power them over the network cable. The phones require up to 25.5 W each. Which PoE standard meets this requirement without over-provisioning?
3. A network engineer configures a switch port to carry traffic for VLANs 10, 20, and 30 between two switches. After applying the configuration, devices in VLAN 10 can communicate across the link, but devices in VLANs 20 and 30 cannot. The engineer runs `show interfaces GigabitEthernet0/1 trunk` and sees that the native VLAN is 10 and VLANs allowed on the trunk are 1-4094. What is the most likely cause of the problem?
4. A network engineer notices that after adding a new Cisco switch to the network, several VLANs have disappeared from all switches in the VTP domain. What is the most likely cause of this issue?
5. A network engineer must compare RIPv2, OSPF, and EIGRP for a new enterprise deployment. Which TWO statements accurately describe characteristics that differentiate these protocols? (Choose TWO)
