CCNA Practice Quiz: 200-301 Quiz 6

1. What term does the OSI model use that is different from the TCP/IP model uses to refer to frame, packet, and segment?

• Presentation
• IEEE Ethernet standard
• Session
• Protocol data unit (PDU)

2. What role does ARP play in the routing process?

• ARP does not play any role in the routing process. Switches use ARP to map IP addresses to MAC addresses in collision domains.
• If a router does not know a destination device's MAC address, it sends an ARP broadcast containing the destination device's IP address and requesting its MAC address.
• If a router knows the MAC and IP address of a destination host, it sends an ARP request to update the other routers' route tables.
• If a router does not know a destination device's IP address, it sends an ARP broadcast containing the destination device's MAC address and requesting its IP address.

3. When using the ip summary-address command, which of the following is true?

• Neighboring devices only have a summary route in their routing tables.
• The interface being configured should be an inbound interface.
• The routing table contains the next-hop interface set to the IP address of the next router.
• The summary route will be added to all inbound interfaces on the router.

4. Which of the following describes route summarization?

• Combines a contiguous set of addresses into a single address.
• Provides a summary of all routes on the entire network.
• Increases the size of the routing table, but reduces network traffic when using OSPF in automatic mode.
• Aggregates multiple routers to appear as the same router.

5. What is the maximum number of paths equal load balancing can support?

• 4
• 12
• 8
• 16

6. Which subcommand can be used to add more routes to the table for additional balancing?

• network [n.n.n.n]
• router eigrp [number]
• no auto-summary
• maximum-paths

7. You are troubleshooting Physical layer issues with the Gi0/1 interface in a router. You need to view and analyze the number of collisions detected on the interface. Which command should you use?

• show interfaces gi0/1
• show interfaces gi0/1 status
• show controllers gi0/1
• show interfaces gi0/1 description

8. You are reviewing the output of the show interfaces command for the Gi0/1 interface on a switch.

Which interface statistic displays the number of collisions that occurred after the 64th byte of the frame was transmitted?

• CRC errors
• Giants
• Late collisions
• Runts

9. The Stuxnet worm was discovered in 2010 and was used to gain sensitive information about Iran's industrial infrastructure. This worm was probably active for about five years before being discovered. During this time, the attacker had access to the target.

Which type of attack was Stuxnet?

• APT
• Virus
• Trojan horse
• Logic bomb

10. Which type of threat actor only uses skills and knowledge for defensive purposes?

• Gray hat
• Hacktivist
• White hat
• Script kiddie
