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

How comfortable were you with the Module 8 review questions?

Which router component holds the routing table, ARP cache, and running configuration file?

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?

• arp -a

• tracert
