CCNA 2 chapter 1

A network administrator enters the command copy running-config startup-config. Which type of memory will the startup configuration be placed into?

• flash

• RAM

• NVRAM

• ROM

Which packet-forwarding method does a router use to make switching decisions when it is using a forwarding information base and an adjacency table?

• fast switching

• Cisco Express Forwarding

• process switching

• flow process

When a router receives a packet, it examines the destination address of the packet and looks in the ———- table to determine the best path to use to forward the packet.

• Routing

• Switching

• MAC

• IP

What are two functions of a router? (Choose two.)

• A router connects multiple IP networks

• It controls the flow of data via the use of Layer 2 addresses

• It determines the best path to send packets

• It provides segmentation at Layer 2

• It builds a routing table based on ARP requests

In order for packets to be sent to a remote destination, what three pieces of information must be configured on a host? (Choose three.)

• hostname

• IP address

• subnet mask

• default gateway

• DNS server address

Which software is used for a network administrator to make the initial router configuration securely?

• SSH client software

• Telnet client software

• HTTPS client software

• terminal emulation client software

Refer to the exhibit. A network administrator has configured R1 as shown. When the administrator checks the status of the serial interface, the interface is shown as being administratively down. What additional command must be entered on the serial interface of R1 to bring the interface up?

• IPv6 enable

• clockrate 128000

• end

• no shutdown

What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?

• The no shutdown command is required to place this interface in an UP state

• It is a logical interface internal to the router

• Only one loopback interface can be enabled on a router

• It is assigned to a physical port and can be connected to other devices

What two pieces of information are displayed in the output of the show ip interface brief command? (Choose two.)

• IP addresses

• MAC addresses

• Layer 1 statuses

• next-hop addresses

• speed and duplex settings

When a router receives a packet, what information must be examined in order for the packet to be forwarded to a remote destination?

• destination MAC address

• destination IP address

• source IP address

• source MAC address
