CCNA Practice Quiz: 200-301 Quiz 31

1. How does TCP handle data sequencing? *This question is required.

• TCP breaks the data into segments, numbers each segment, and passes them to UDP, which sequences the segments into the correct order.
• TCP does not sequence the data; it simply passes numbered segments created at a higher layer in the sequence defined.
• TCP breaks user data into segments, numbers each segment, places them in the correct sequence, and sends each one in order, waiting for an acknowledgement before sending the next segment.
• TCP breaks user data into segments, numbers each segment, and sends each segment in order, without waiting for an acknowledgement.

2. Which of the following devices is most likely to be assigned a public IP address? *This question is required.

• A database server used by your company's website for storing customer information
• A router on your company network that segments your LAN into two subnets
• A router that connects your home network to the internet
• A workstation on your company network that has internet access

3. Which of the following are considered stable neighbor states? (Choose two) *This question is required.

• Exchange
• 2-way
• Init
• Loading state
• Full state

4. One of the interfaces in a router with OSPF enabled is connected to a network link where no other routers reside. You want to prevent this interface from sending OSPF Hello messages, as there are no other routers on that network to respond.

Which command should you use? *This question is required.

• passive-interface < type > < number >
• clear ipv6 ospf process
• ipv6 ospf < process id > area < number >
• no passive interface < type > < number >

5. What purposes does a wireless site survey fulfill? (Choose two) *This question is required.

• Determine the noise floor in the desired frequency range
• Identify the recommended 100-degree separation angle for alternating access points
• Identify the coverage area and preferred placement of access points
• Identify existing or potential sources of interference
• Document existing infrared traffic in the 5.4 GHz spectrum

6. Which enterprise deployment has limited mobility and is difficult to manage? *This question is required.

• Distributed wireless mesh infrastructure
• Hub-and-spoke infrastructure
• Independent access points
• Wireless bridges

7. Which problem does the Spanning Tree Protocol prevent? *This question is required.

• It prevents message loops from developing when a switch or bridge is connected to the same location more than once.
• It doesn't prevent any problem. Instead, it creates an overall routing table (a span tree) for the entire network.
• It prevents buffer overflows by defining source-quench messages that a receiving device sends to the transmitting device.
• It prevents route tables from becoming outdated by decreasing the convergence time on a network.

8. You are configuring an 1841 Cisco router for interVLAN communication. You would like to use one physical interface to handle the incoming traffic from VLANs 2 and 10. The switch connected to the router is sending 802.1Q encapsulated traffic for VLAN 2, but is not encapsulating VLAN 10.

Which command would you use to ensure that the router correctly handles traffic coming from the switch? *This question is required.

• router(config-if)#encapsulation dot1q 10 native
• router(config-subif)#encapsulation dot1q 2 native
• router(config-if)#encapsulation dot1q 2 native
• router(config-subif)#encapsulation dot1q default native
• router(config-subif)#encapsulation dot1q 10 native

9. Currently, your NetFlow router is configured to redirect records to a NetFlow Collector with an IP address of 172.17.8.25 on UDP port 2055.

By default, NetFlow uses the IP address of the interface that packets are sent from as the source IP address for records. However, for security reasons, you want to obscure the source address of the NetFlow router by specifying that all NetFlow records originate from the loopback interface of the router.

Which command should you use? *This question is required.

• ip flow-export version loopback 0
• ip flow-export source loopback 0
• ip flow egress loopback 0
• ip flow-export destination loopback 0

10. The storage area where NetFlow data is stored on a device is known as what? *This question is required.

• NetFlow management collector
• Export or transport mechanism
• NetFlow Cache
• Packet header
