Where will a frame be directed if the destination IP address is on a remote network?
To the MAC address of the default gateway.
To the destination host MAC address.
To the destination remote switch.
To the MAC address of the local switch.
Which of the statements regarding the IP protocol is true?
IP encapsulation is modified based on different network media types.
IP relies on Layer 2 protocols for transmission error control.
MAC addresses are used during the IP packet encapsulation.
IP requires upper layers such as the Transport layer to resend missing frames.
What function does the IPv4 127.0.0.1 or ::1 IPv6 loopback address provide?
To test if the device has end-to-end connectivity.
To test that a device has a proper network IP address.
To test that the device has a properly configured default gateway.
To test that the TCP/IP layer 3 is operational.
What are two services provided by the OSI network layer?
Performs error and collision detection.
Performs error detection and places frames onto the media.
Encapsulates the IP addresses and routes frames towards the destination network.
Determines the correct port number and application.
Which of the following are characteristics of the IP protocol?
It is media dependant and connection-oriented.
It performs error detection and packet re-ordering.
It provides security and packet tracking.
It is connectionless and best-effort.
Why is NAT not needed in IPv6?
NAT is not necessary because IPv6 supports end to end delivery of a packet with the same IP address.
NAT is not necessary because security is inherently built into IPv6.
IPv6 header improves packet handling with fewer fields therefore there is no need for NAT.
Multiple Ipv6 addresses can be assigned to adapters increasing the number of routes eliminating the need for NAT.
Which IPv4 packet header field would contain a unicast, multicast, or broadcast address?
Protocol
Header checksum
Time to Live (TTL)
Destination IPv4 address
What IPv4 header field identifies the upper-layer protocol (TCP, UDP, ICMP) contained within the packet?
Version
Protocol
Differentiated Services
Traffic Class
Which header field prevents an IPv6 packet from endlessly traversing a network without being delivered?
Protocol
Version
Hop limit
Traffic Class
Which field in the IPv4 header is used to determine the priority of each packet when setting the precedence of one type of data over another?
Differentiated Services
Hop Limit
Next Header
Version
Which route type can be added to a routing table to forward packets if there isn't another specific network route corresponding to the destination IP address?
Directly-connected routes
Local routes created by interfaces
Default static route
Remote routes
What type of route is indicated by the code C in an IPv4 routing table on a Cisco router and is implemented by configuring a local interface on the router?
Static route
Default route
Directly connected route
EIGRP dynamic route
What is one advantage that the IPv6 header offers over IPv4?
Provides more efficient packet handling due to fewer fields.
Contains smaller-sized source and destination IP addresses.
Requires little processing for checksum of the header.
Provides a smaller header size than the IPv4.
What command can be used on a PC to display a routing table?
show ip route
netstat -r
tracert
ping -a
