Which command can be used on a Windows host to display the routing table

netstat -r

What information is added during encapsulation at OSI layer 3?

source and destination IP address

Which characteristic describes an IPv6 enhancement over IPv4

The IPv6 header is simpler than the IPv4 header is, which improves packet heading

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

destination IP address

A computer has to send a packet to a destination host in the same LAN. How will the packet be sent?

The packet will be sent directly to the destination host

Which IPv4 address can a host use to ping the loopback interface

127.0.0.1

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary

Upper-layer connection-oriented protocols keep track of the data received and can request retransmission form the upper-level protocols on the sending host

what was the reason for the creation and implementation of IPv6

to relieve IPv4 address depletion

Which information is used by routers to forward a data packet toward its destination

destination IP address

which field in an IPv6 packet is used by the router to determine if a packet has expired and should be dropped

Hop limit

what type of information is contained in an ARP table

IPv4 address to MAC address mappings

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 s host is using to reach the default gateway

arp -a

What will a layer 2 switch do when the destination MAC address of a received frame is not in the MAC table

it forwards the frame out of all ports except for the port at which the frame was received

What is one function of the ARP protocol

resolving an IPv4 address to a MAC address

When an IPv4 packet is sent to a host on a remote network, what information is provided by ARP

the MAC address of the router interface closest to the sending host

The ARP table in a switch maps which two types of address together

Layer 3 address to a layer 2 address

which destination address is used in an ARP request frame

FFFF.FFFF.FFF

A router boots and enters setup mode. What is the reason for this

The configuration file is missing from NVRAM

Company policy requires using the most secure methos to safeguard access to the privileged exec and configuration mode on the routers. The privileged exec password is trustknow1. Which of the following commands achieves the goal of providing the highest level of security

enable secret trustknow1

Which command can be used on a cisco router to display all interfaces, the IPv4 address assigned and the current status

show ip interface brief

Which CLI mode allows users to access all device commands, such as those used for configuration, management. and troubleshooting

privileged EXEC mode

What is the purpose of the startup configuration file on a cisco router

to contain the commands that are used to initially configure a router on startup

Which characteristic describes the default gateway of a host computer

the logical address of the router interface on the same network as the host computer

what is stored in the NVRAM of a cisco router

the startup configuration

which 2 parts are components of an IPv4 address

• host portion

• network portion

What is the purpose of the subnet mask in conjunction with an IP address

to determine the subnet to which the host belongs to
