CCNA 1 Chapter 2 v5 Exam Answers 2016

1.

Refer to the exhibit. A switch was configured as shown. A ping to the default gateway was issued, but the ping was not successful. Other switches in the same network can ping this gateway. What is a possible reason for this?

The default gateway address must be 192.168.10.1.
The ip default-gateway command has to be issued in the VLAN interface configuration mode.
The VLAN IP address and the default gateway IP address are not in the same network.
The no shutdown command was not issued for VLAN 1.
The local DNS server is not functioning correctly.

While trying to solve a network issue, a technician made multiple changes to the current router configuration file. The changes did not solve the problem and were not saved. What action can the technician take to discard the changes and work with the file in NVRAM?

Issue the reload command without saving the running configuration.
Close and reopen the terminal emulation software.
Delete the vlan.dat file and reboot the device.
Issue the copy startup-config running-config command.

3.
Why is it important to configure a hostname on a device?

to allow local access to the device through the console port
a Cisco router or switch only begins to operate when its hostname is set
to identify the device during remote access (SSH or telnet)
a hostname must be configured before any other parameters

4.
Which procedure is used to access a Cisco 2960 switch when performing an initial configuration in a secure environment?

Use the console port to locally access the switch from a serial or USB interface of the PC.
Use Secure Shell to remotely access the switch through the network​.
Use Telnet to remotely access the switch through the network.
Use the AUX port to locally access the switch from a serial or USB interface of the PC.

5.
What criterion must be followed in the design of an IPv4 addressing scheme for end devices?

Each local host should be assigned an IP address with a unique network component.
Each IP address must match the address that is assigned to the host by DNS.
Each IP address must be unique within the local network.
Each IP address needs to be compatible with the MAC address.

6.

DHCP allows users to refer to locations by a name rather than an IP address.
Hosts always have the same IP address and are therefore always reachable.

what type of device is at the destination
if the TCP/IP stack is functioning on the PC without putting traffic on the wire
the path that traffic will take to reach the destination
