CCNA 1 R&S Introduction to Networks Chapter 5 Exam

A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in its ARP cache. How will the device obtain a destination MAC address?

Which address or combination of addresses does a Layer 3 switch use to make forwarding decisions?

What are two potential network problems that can result from ARP operation? (Choose two.)

Launch PT

Hide and Save PT
Open the PT Activity. Perform the tasks in the activity instruction and then answer the question.

What destination address will PC1 include in the destination address field of the Ethernet frame that it sends to PC2?

How does adding an Ethernet line card affect the form factor of a switch?

Which two statements are correct about MAC and IP addresses during data transmission if NAT is not involved? (Choose two.)

What is the Layer 2 multicast MAC address that corresponds to the Layer 3 IPv4 multicast address 224.139.34.56?

What is the purpose of the preamble in an Ethernet frame?

A Layer 2 switch is used to switch incoming frames from a 1000BASE-T port to a port connected to a 100Base-T network. Which method of memory buffering would work best for this task?

A network administrator is connecting two modern switches using a straight-through cable. The switches are new and have never been configured. Which three statements are correct about the final result of the connection? (Choose three.)

Refer to the exhibit. PC1 issues an ARP request because it needs to send a packet to PC2. In this scenario, what will happen next?​

What is a characteristic of a contention-based access method?

What statement illustrates a drawback of the CSMA/CD access method?

When would a switch record multiple entries for a single switch port in its MAC address table?

Which two statements describe a fixed configuration Ethernet switch? (Choose two.)

Which two statements describe features or functions of the logical link control sublayer in Ethernet standards? (Choose two.)

A network administrator issues the following commands on a Layer 3 switch:

DLS1(config)# interface f0/3
DLS1(config-if)# no switchport
DLS1(config-if)# ip address 172.16.0.1 255.255.255.0
DLS1(config-if)# no shutdown
DLS1(config-if)# end

What is the administrator configuring?

Which statement is true about MAC addresses?

Refer to the exhibit. The exhibit shows a small switched network and the contents of the MAC address table of the switch. PC1 has sent a frame addressed to PC3. What will the switch do with the frame?

Fill in the blank.

What are two features of ARP? (Choose two.)

Match the characteristic to the forwarding method.

Match the seven fields of an Ethernet frame to their respective contents
