Question 1 of 25
1. Question
1 pointsHow many bits are in an IPv4 address?Correct
Incorrect
Hint
An IPv4 address is comprised of 4 octets of binary digits, each containing 8 bits, resulting in a 32-bit address. -
Question 2 of 25
2. Question
1 pointsWhich two parts are components of an IPv4 address? (Choose two.)Correct
Incorrect
Hint
An IPv4 address is divided into two parts: a network portion – to identify the specific network on which a host resides, and a host portion – to identify specific hosts on a network. A subnet mask is used to identify the length of each portion. -
Question 3 of 25
3. Question
1 pointsWhat does the IP address 172.17.4.250/24 represent?Correct
Incorrect
Hint
The /24 shows that the network address is 172.17.4.0. The broadcast address for this network would be 172.17.4.255. Useable host addresses for this network are 172.17.4.1 through 172.17.4.254. -
Question 4 of 25
4. Question
1 pointsWhat is the purpose of the subnet mask in conjunction with an IP address?Correct
Incorrect
Hint
With the IPv4 address, a subnet mask is also necessary. A subnet mask is a special type of IPv4 address that coupled with the IP address determines the subnet of which the device is a member. -
Question 5 of 25
5. Question
1 pointsWhat subnet mask is represented by the slash notation /20?Correct
Incorrect
Hint
The slash notation /20 represents a subnet mask with 20 1s. This would translate to: 11111111.11111111.11110000.0000, which in turn would convert into 255.255.240.0. -
Question 6 of 25
6. Question
1 pointsA message is sent to all hosts on a remote network. Which type of message is it?Correct
Incorrect
Hint
A directed broadcast is a message sent to all hosts on a specific network. It is useful for sending a broadcast to all hosts on a nonlocal network. A multicast message is a message sent to a selected group of hosts that are part of a subscribing multicast group. A limited broadcast is used for a communication that is limited to the hosts on the local network. A unicast message is a message sent from one host to another. -
Question 7 of 25
7. Question
1 pointsWhat are three characteristics of multicast transmission? (Choose three.)Correct
Incorrect
Hint
Broadcast messages consist of single packets that are sent to all hosts on a network segment. These types of messages are used to request IPv4 addresses, and map upper layer addresses to lower layer addresses. A multicast transmission is a single packet sent to a group of hosts and is used by routing protocols, such as OSPF and RIPv2, to exchange routes. The address range 224.0.0.0 to 224.0.0.255 is reserved for link-local addresses to reach multicast groups on a local network. -
Question 8 of 25
8. Question
1 pointsWhich three IP addresses are private ? (Choose three.)Correct
Incorrect
Hint
The private IP addresses are within these three ranges: 10.0.0.0 – 10.255.255.255 172.16.0.0 – 172.31.255.255 192.168.0.0 – 192.168.255.255 -
Question 9 of 25
9. Question
1 pointsWhich two IPv4 to IPv6 transition techniques manage the interconnection of IPv6 domains? (Choose two.)Correct
Incorrect
Hint
There are three techniques to allow IPv4 and IPv6 to co-exist on a network. Dual stack allows IPv4 and IPv6 to coexist on the same network segment. Dual stack devices run both IPv4 and IPv6 protocol stacks simultaneously. Tunneling is a method of transporting an IPv6 packet over an IPv4 network. The IPv6 packet is encapsulated inside an IPv4 packet, similar to other types of data. Network Address Translation 64 (NAT64) allows IPv6-enabled devices to communicate with IPv4-enabled devices using a translation technique similar to NAT for IPv4 -
Question 10 of 25
10. Question
1 pointsWhich of these addresses is the shortest abbreviation for the IP address: 3FFE : 1044 : 0000 : 0000 : 00AB : 0000 : 0000 : 0057?Correct
Incorrect
-
Question 11 of 25
11. Question
1 pointsWhat type of address is automatically assigned to an interface when IPv6 is enabled on that interface?Correct
Incorrect
Hint
When IPv6 is enabled on any interface, that interface will automatically generate an IPv6 link-local address. -
Question 12 of 25
12. Question
1 pointsWhat are two types of IPv6 unicast addresses? (Choose two.)Correct
Incorrect
Hint
Multicast, anycast, and unicast are types of IPv6 addresses. There is no broadcast address in IPv6. Loopback and link-local are specific types of unicast addresses. -
Question 13 of 25
13. Question
1 pointsWhat are three parts of an IPv6 global unicast address? (Choose three.)Correct
Incorrect
Hint
There are three elements that make up an IPv6 global unicast address. A global routing prefix which is provided by an ISP, a subnet ID which is determined by the organization, and an interface ID which uniquely identifies the interface interface of a host. -
Question 14 of 25
14. Question
1 pointsAn administrator wants to configure hosts to automatically assign IPv6 addresses to themselves by the use of Router Advertisement messages, but also to obtain the DNS server address from a DHCPv6 server. Which address assignment method should be configured?Correct
Incorrect
Hint
Stateless DHCPv6 allows clients to use ICMPv6 Router Advertisement (RA) messages to automatically assign IPv6 addresses to themselves, but then allows these clients to contact a DHCPv6 server to obtain additional information such as the domain name and address of DNS servers. SLAAC does not allow the client to obtain additional information through DHCPv6, and stateful DHCPv6 requires that the client receive its interface address directly from a DHCPv6 server. RA messages, when combined with an EUI-64 interface identifier, are used to automatically create an interface IPv6 address, and are part of both SLAAC and stateless DHCPv6. -
Question 15 of 25
15. Question
1 pointsWhich protocol supports Stateless Address Autoconfiguration (SLAAC) for dynamic assignment of IPv6 addresses to a host?Correct
Incorrect
Hint
SLAAC uses ICMPv6 messages when dynamically assigning an IPv6 address to a host. DHCPv6 is an alternate method of assigning an IPv6 addresses to a host. ARPv6 does not exist. Neighbor Discovery Protocol (NDP) provides the functionality of ARP for IPv6 networks. UDP is the transport layer protocol used by DHCPv6. -
Question 16 of 25
16. Question
1 pointsWhich two things can be determined by using the ping command? (Choose two.)Correct
Incorrect
Hint
A ping command provides feedback on the time between when an echo request was sent to a remote host and when the echo reply was received. This can be a measure of network performance. A successful ping also indicates that the destination host was reachable through the network. -
Question 17 of 25
17. Question
1 pointsWhat is the purpose of ICMP messages?Correct
Incorrect
Hint
The purpose of ICMP messages is to provide feedback about issues that are related to the processing of IP packets. -
Question 18 of 25
18. Question
1 pointsWhat is indicated by a successful ping to the ::1 IPv6 address?Correct
Incorrect
Hint
The IPv6 address ::1 is the loopback address. A successful ping to this address means that the TCP/IP stack is correctly installed. It does not mean that any addresses are correctly configured. -
Question 19 of 25
19. Question
1 pointsA user is executing a tracert to a remote device. At what point would a router, which is in the path to the destination device, stop forwarding the packet?Correct
Incorrect
Hint
When a router receives a traceroute packet, the value in the TTL field is decremented by 1. When the value in the field reaches zero, the receiving router will not forward the packet, and will send an ICMP Time Exceeded message back to the source. -
Question 20 of 25
20. Question
1 pointsWhat field content is used by ICMPv6 to determine that a packet has expired?Correct
Incorrect
Hint
ICMPv6 sends a Time Exceeded message if the router cannot forward an IPv6 packet because the packet expired. The router uses a hop limit field to determine if the packet has expired, and does not have a TTL field. -
Question 21 of 25
21. Question
1 pointsFill in the blank.- The decimal equivalent of the binary number 10010101 is (149)
Correct
Incorrect
Hint
To convert a binary number to the decimal equivalent, add the value of the position where any binary 1 is present. -
Question 22 of 25
22. Question
1 pointsFill in the blank.- The binary equivalent of the decimal number 232 is (11101000)
Correct
Incorrect
Hint
To convert a decimal number to binary, first determine if the decimal number is equal to or greater than 128. In this case, because 232 is larger than 128, a 1 is placed in the bit position for decimal value 128 and the value of 128 is then subtracted from 232. This results in the value of 104. We then compare this value to 64. As 104 is larger than 64, a 1 is placed in the bit position for the decimal value 64 and the value of 64 is subtracted from 104. The remaining value is then 40. The process should be continued for all the remaining bit positions. -
Question 23 of 25
23. Question
1 pointsFill in the blank.- What is the decimal equivalent of the hex number 0x3F? (63)
Correct
Incorrect
Hint
To convert from hexadecimal to decimal, multiply each digit by the place value that is associated with the position of the digit and add the results. -
