How large are IPv4 addresses?
- A.
8 bits
- B.
16 bits
- C.
32 bits
- D.
64 bits
- E.
128 bits
Correct Answer
C. 32 bitsExplanation
IPv4 addresses are 32 bits in size. This means that each address consists of 32 binary digits or bits. IPv4 addresses are used to identify devices on a network, and the 32-bit size allows for a total of approximately 4.3 billion unique addresses. However, due to the increasing number of devices connected to the internet, the limited number of IPv4 addresses has led to the development of IPv6, which uses 128 bits and provides a much larger address space.Rate this question:

Refer to the graphic. A user at the workstation cannot connect to the server. All cables have been tested and are working and all devices have IP addressing. However, the user cannot ping the server. What is causing the problem?
- A.
The router interface does not have a default gateway.
- B.
The switch does not have an IP address and default gateway.
- C.
The workstation and server are on different logical networks.
- D.
The workstation does not know the MAC address of the switch.
Correct Answer
C. The workstation and server are on different logical networks.Explanation
The problem is caused by the workstation and server being on different logical networks. In order for devices to communicate with each other on a network, they must be on the same logical network and have compatible IP addresses. Since the user cannot ping the server, it indicates that they are not on the same logical network. This could be due to incorrect subnetting or misconfiguration of IP addresses on either the workstation or the server.Rate this question:

Given a host with the IP address 172.32.65.13 and a default subnet mask, to which network does the host belong?
- A.
172.32.65.0
- B.
172.32.65.32
- C.
172.32.0.0
- D.
172.32.32.0
Correct Answer
C. 172.32.0.0Explanation
The host with the IP address 172.32.65.13 belongs to the network 172.32.0.0. This is because the default subnet mask for a Class B network is 255.255.0.0, which means that the first two octets (172.32) represent the network portion of the IP address, while the last two octets (65.13) represent the host portion. Therefore, the host belongs to the network 172.32.0.0.Rate this question:
-
- 5.
Which default subnet mask provides the most host bits?
- A.
255.0.0.0
- B.
255.255.0.0
- C.
255.255.255.0
- D.
255.255.255.252
Correct Answer
A. 255.0.0.0Explanation
The subnet mask 255.0.0.0 provides the most host bits because it only has 8 bits in the network portion and 24 bits in the host portion. This allows for a larger number of possible host addresses within the network. In contrast, the other subnet masks have more bits in the network portion, which reduces the number of available host addresses.Rate this question:
-
- 6.
How many bits are available for Class B host IP addresses using a default subnet mask?
- A.
4
- B.
8
- C.
16
- D.
24
Correct Answer
C. 16Explanation
Class B host IP addresses use a default subnet mask of 16 bits. This means that the first 16 bits of the IP address are reserved for the network address, while the remaining 16 bits are available for the host address. This allows for a maximum of 65,536 host addresses within each Class B network.Rate this question:
-
- 7.
How many usable hosts are available given a Class C IP address with the default subnet mask?
- A.
254
- B.
255
- C.
256
- D.
510
- E.
511
- F.
512
Correct Answer
A. 254Explanation
A Class C IP address has a default subnet mask of 255.255.255.0, which means that the first three octets are fixed and the last octet can be used to assign host addresses. In this case, the last octet can have 256 possible values (0-255), but the first and last addresses are reserved for network and broadcast addresses respectively. Therefore, the number of usable hosts is 256-2=254.Rate this question:
-
- 8.
Assuming a default mask, which portion of the IP address 175.124.35.4 represents the host?
- A.
175.124
- B.
35.4
- C.
.4
- D.
124.35.4
- E.
175.124.35
Correct Answer
B. 35.4Explanation
The host portion of an IP address refers to the part that identifies the specific device within a network. In this case, the IP address is 175.124.35.4. The portion "35.4" represents the host because it uniquely identifies the device within the network. The other portions, such as "175.124" and "124.35.4", represent the network and subnet respectively, but they do not identify the specific device.Rate this question:

What destination IP address is used in a unicast packet?
- A.
A specific host
- B.
A group of host
- C.
The default gateway
- D.
The network broadcast address
Correct Answer
A. A specific hostExplanation
A unicast packet is sent from one source to a specific destination host. Unlike multicast or broadcast packets that are sent to multiple hosts, a unicast packet is intended for a single host. Therefore, the destination IP address used in a unicast packet is the IP address of the specific host that the packet is intended for.Rate this question:

What is the destination MAC address in a multicast Ethernet frame?
- A.
The MAC address of the sending host
- B.
The MAC address of the destination host
- C.
An address that begins with 01-00-5E in hexadecimal
- D.
a 48-bit hexadecimal address expressed as FF-FF-FF-FF-FF-FF
Correct Answer
C. An address that begins with 01-00-5E in hexadecimalExplanation
The destination MAC address in a multicast Ethernet frame is an address that begins with 01-00-5E in hexadecimal. Multicast addresses are used to send data to a group of hosts rather than a single destination host. The address range starting with 01-00-5E is reserved for IPv4 multicast addresses, allowing efficient distribution of data to multiple recipients on a network.Rate this question:

- A.
Broadcast
- B.
Simulcast
- C.
Multicast
- D.
Unicast
Correct Answer
D. UnicastExplanation
This is a unicast message because Yvonne is talking to her friend on the phone, which means the message is being sent to a specific recipient. Unicast refers to the transmission of data from one sender to one receiver, making it a one-to-one communication.Rate this question:
-
- 13.
What information must be included within a unicast message for it to be delivered on an Ethernet network?
- A.
MAC and IP addresses for the default router
- B.
IP address and subnet mask of the default gateway
- C.
MAC and IP addresses that correspond to a destination groupe
- D.
MAC and IP addresses that correspond to a specific destination host
Correct Answer
D. MAC and IP addresses that correspond to a specific destination hostExplanation
To ensure the delivery of a unicast message on an Ethernet network, the message must include the MAC and IP addresses that correspond to a specific destination host. The MAC address is necessary to identify the specific network interface card (NIC) of the destination host, while the IP address is used for routing the message to the correct destination on the network. By including both the MAC and IP addresses of the specific destination host, the Ethernet network can accurately deliver the unicast message to the intended recipient.Rate this question:

A PC obtains its IP address from a DHCP server. If the PC is taken off the network for repair, what happens to the IP address configuration?
- A.
The configuration is permanent and nothing changes.
- B.
The address lease is automatically renewed until the PC is returned.
- C.
The address is returned to the pool for reuse when the lease expires.
- D.
The configuration is held by the server to be reissued when the PC is returned.
Correct Answer
C. The address is returned to the pool for reuse when the lease expires.Explanation
When a PC is taken off the network for repair, its IP address configuration is not permanent. The IP address that was assigned to the PC is returned to the DHCP server's address pool for reuse when the lease expires. This means that when the PC is repaired and connected back to the network, it will be assigned a new IP address from the DHCP server.Rate this question:

Correct Answer(s)
B. The destination IP address is 255.255.255.255.
D. The message comes from a client seeking an IP address.
E. All hosts receive the message, but only a DHCP server replies.Explanation
A DHCP Discover message is sent by a client seeking an IP address. The message is broadcasted to all hosts on the network, which is why the destination IP address is 255.255.255.255. The message is received by all hosts, but only a DHCP server will reply. The source MAC address is not specified as 48 ones (FF-FF-FF-FF-FF-FF) in a DHCP Discover message.Rate this question:

Refer to the graphic. A host connects to a Linksys integrated router that is also a DHCP server and receives an IP address from it. Which address does the host need to access the ISP and the Internet?
- A.
IP address of the destination host
- B.
Public gateway IP address of the ISP
- C.
External IP address of the integrated router that connects to the ISP
- D.
Internal IP address of the integrated router that connects to the local network
Correct Answer
D. Internal IP address of the integrated router that connects to the local networkExplanation
The host needs to access the Internet through the internal IP address of the integrated router that connects to the local network. This is because the integrated router acts as a gateway for the host to connect to the ISP and the Internet. The internal IP address of the router is used for communication within the local network, and the router then forwards the traffic to the ISP using its external IP address.Rate this question:
-
- 18.
Which statement is true concerning private IP addresses?
- A.
Ensures that two networks separated by the Internet use unique IP network numbers
- B.
Allows internal hosts to communicate with servers across the Internet
- C.
Solves the issue of a finite number of available public IP addresses
- D.
Allows for ISPs to be able to quickly determine network location
Correct Answer
C. Solves the issue of a finite number of available public IP addressesExplanation
Private IP addresses solve the issue of a finite number of available public IP addresses. This is because private IP addresses are used within a local network, such as a home or office, and are not directly accessible from the internet. By using private IP addresses, organizations can conserve the limited supply of public IP addresses and allow multiple devices to share a single public IP address. This helps alleviate the problem of running out of public IP addresses, especially as the number of internet-connected devices continues to grow.Rate this question:

What is one of the purposes of NAT?
- A.
Filters network traffic based on IP address ranges
- B.
Prevents external users from detecting the IP addresses used on a network
- C.
inspects traffic that might be harmful or used in an attack against the network
- D.
Translates IP addresses into easy-to-remember domain names
Correct Answer
B. Prevents external users from detecting the IP addresses used on a networkExplanation
NAT (Network Address Translation) is a technique used to hide the IP addresses of devices on a network from external users. By translating the IP addresses of the devices into a single public IP address, it prevents external users from directly accessing or detecting the individual IP addresses of devices on the network. This adds a layer of security and privacy to the network, as it makes it more difficult for potential attackers to target specific devices or gather information about the network's structure.Rate this question:

Which two statements describe packets that are sent through a Linksys integrated router using NAT? (Choose two.)
- A.
Packets that are sent to any destination need to be translated.
- B.
Packets that are sent to hosts on the same network need to be translated.
- C.
Packets that are sent to a destination outside the local network need to be translated.
- D.
Packets that are sent to a destination outside a local network do not need to be translated
- E.
Packets that are sent between hosts on the same local network do not need to be translated.
Correct Answer(s)
C. Packets that are sent to a destination outside the local network need to be translated.
E. Packets that are sent between hosts on the same local network do not need to be translated.Explanation
Packets that are sent to a destination outside the local network need to be translated because the router uses Network Address Translation (NAT) to translate the private IP addresses of the local network to the public IP address of the router. This allows the packets to be properly routed over the internet. On the other hand, packets that are sent between hosts on the same local network do not need to be translated because they are already using the same private IP address range and can communicate directly without translation.Rate this question:

Refer to the graphic. NAT and DHCP are installed on the Linksys integrated router. Which IP address is most likely to be assigned to the local computer, Host1?
- A.
10.0.0.17
- B.
128.107.1.2
- C.
192.135.250.0
- D.
209.165.201.1
Correct Answer
A. 10.0.0.17Explanation
The most likely IP address to be assigned to the local computer, Host1, is 10.0.0.17. This is because NAT (Network Address Translation) and DHCP (Dynamic Host Configuration Protocol) are installed on the Linksys integrated router. NAT allows multiple devices on a local network to share a single public IP address, and DHCP is responsible for assigning IP addresses to devices on the network. The IP address 10.0.0.17 is within the range of private IP addresses typically used by routers for local networks.Rate this question:
