Which command can be used on a Windows host to display the routing table?
netstat -s
show ip route
netstat -r
tracert
What information is added during encapsulation at OSI Layer 3?
source and destination MAC address
source and destination application protocol
source and destination port number
source and destination IP address
Which characteristic describes an IPv6 enhancement over IPv4?
IPv6 addresses are based on 128-bit flat addressing as opposed to IPv4 which is based on 32-bit hierarchical addressing.
The IPv6 header is simpler than the IPv4 header is, which improves packet handling.
Both IPv4 and IPv6 support authentication, but only IPv6 supports privacy capabilities.
The IPv6 address space is four times bigger than the IPv4 address space.
Which statement accurately describes a characteristic of IPv4?
All IPv4 addresses are assignable to hosts
IPv4 has a 32-bit address space
An IPv4 header has fewer fields than an IPv6 header has
IPv4 natively supports IPsec
Which field in an IPv6 packet is used by the router to determine if a packet has expired and should be dropped?
TTL
Hop Limit
Address Unreachable
No Route to Destination
Which IPv4 address can a host use to ping the loopback interface?
126.0.0.1
127.0.0.0
126.0.0.0
127.0.0.1
What was the reason for the creation and implementation of IPv6?
To make reading a 32-bit address easier
To relieve IPv4 address depletion
To provide mode address space in the Internet Names Registry
To allow NAT support for private addressing

A cybersecurity analyst believes an attacker is spoofing the MAC address of the default gateway to perform a man-in-the-middle attack. Which command should the analyst use to view the MAC address a host is using to reach the default gateway?
ipconfig .all
route print
netstat -r
arp -a
tracert
Which two ICMPv6 messages are used during the Ethernet MAC address resolution process? (Choose two.)
router solicitation
router advertisement
neighbor solicitation
neighbor advertisement
echo request
How does the ARP process use an IPv4 address?
To determine the MAC address of the remote destination host
To determine the MAC address of a device on the same network
to determine the amount of time a packet takes when traveling from source to destination
To determine the network number based on the number of bits in the IPv4 address
What addresses are mapped by ARP?
IPv4 address to a destination MAC address
destination IPv4 address to the source MAC address
destination address to the destination host name
destination MAC address to the source IPv4 address
When an IPv4 packet is sent to a host on a remote network, what information is provided by ARP?
The IPv4 addresss f the destination host
The IPv4 address of the default gateway
The MAC address of the router interface closest to the sending host
The MAC address of the switch port that connects to the sending host
Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame?
It drops the frame
It sends the frame to all ports except the port on which it received the frame
It sends the frame to all ports that are registered to forward broadcasts
It sends the frame to all ports

Which statement regarding the service password-encryption command is true?
It is configured in privileged EXEC mode.
It encrypts only line mode passwords
As soon as the service password-encryption command is entered, all currently set passwords formerly displayed in plain text are encrypted.
To see the passwords encrypted by the service password-encryption command in plain text, issue the no service password-encryption command
A router boots and enters setup mode. What is the reason for this?
The IOS image is corrupt
Cisco IOS is missing from flash memory
The configuration file is missing from the NVRAM
The POST process has detected hardware failure
Company policy requires using the most secure method to safeguard access to the privileged exec and configuration mode on the routers. The privileged exec password is trustknow1. Which of the following router commands achieves the goal of providing the highest level of security?
secret password trustknow1
enable password trustknow1
service password-encryption
enable secret trustknow1

Which CLI mode allows users to access all device commands, such as those used for configuration, management, and troubleshooting?
user EXEC mode
privileged EXEC mode
global configuration mode
interface configuration mode
Which command is used to encrypt all passwords in a router configuration file?
Router_A (config) # enable secret <password>
Router_A (config) # service password-encryption
Router_A (config) # enable password <password>
Router_A (config) # encrypt password
Which characteristic describes the default gateway of a host computer?

The physical address of the switch interface connected to the host computer
The physical address of the router interface on the same network as the host computer
The logical address assigned to the switch interface connected to the router
