Question 1

____ IP addresses are designed to be used only on a private internal network and cannot be used on the Internet.&#10;A) Public&#10;B) Routable&#10;C) Routing&#10;D) Private

Accepted Answer

Private IP addresses are documented in RFC 1918 and are designed for use within a private network rather than over the Internet. These addresses are not routable on the public Internet and allow organizations to create their own internal network without requiring unique IP addresses for every device. This helps to preserve the limited pool of publicly available IP addresses.

Question 2

____ are usually created by grouping together computers by Internet protocol (IP) addresses.&#10;A) Segment domains&#10;B) Collision domains&#10;C) Subnets&#10;D) Network segments

Accepted Answer

Subnets are created by grouping together computers by IP addresses.

Question 3

____ is used to create smaller segments for security purposes.&#10;A) CSMA/CA&#10;B) CSMA/CD&#10;C) Ethernet&#10;D) Segmentation

Accepted Answer

Segmentation is the process of dividing a larger network into smaller segments to improve performance and security. By creating smaller segments, it becomes easier to manage and secure each segment individually, reducing the risk of unauthorized access or data breaches. CSMA/CA and CSMA/CD are both access control methods used in Ethernet networks, but they do not have a direct connection to segmentation.

Question 4

In a standard wired Ethernet network, all devices share the same media and a device can send a packet at any time rather than in a fixed or predictable fashion (known as ____ networking).&#10;A) deterministic&#10;B) sequential&#10;C) polling&#10;D) non-deterministic

Accepted Answer

In non-deterministic networking, devices share the same media and have no fixed or predictable transmission patterns. Ethernet networks are commonly non-deterministic and allow for devices to send packets at any time, leading to the possibility of collisions and the need for collision detection and avoidance techniques.

Question 5

One standard for marking VLAN packets is the IEEE ____ standard.&#10;A) 802.1q&#10;B) 802.1r&#10;C) 802.1v&#10;D) 802.1z

Accepted Answer

The IEEE 802.1q standard is used for marking VLAN packets. It adds a VLAN tag to the Ethernet frame, indicating which VLAN the frame belongs to. The other options, 802.1r, 802.1v, and 802.1z, are also IEEE standards, but they are not specifically related to VLAN packet marking.

Question 6

Security by obscurity is sometimes criticized as being too weak.

Accepted Answer

Security by obscurity relies on keeping information secret or hidden as a means of protection. However, this approach is often criticized as it does not address the root cause of the security issue and can be easily circumvented by attackers who are able to uncover the hidden information. It is generally recommended that security measures be based on strong encryption, authentication, and access controls instead of obscurity.

Question 7

IEEE 802.11 WLANs have more collisions than wired Ethernet networks.

Accepted Answer

IEEE 802.11 WLANs (Wireless Local Area Networks) use a protocol called CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) to minimize the chance of collisions, whereas wired Ethernet networks use CSMA/CD (Carrier Sense Multiple Access with Collision Detection) which allows for collisions and then manages them. Since wireless networks cannot detect collisions as easily as wired networks, they are designed to avoid them from the outset, leading to fewer collisions in practice.

Question 8

When a sending device on a LAN sends a packet that is intended for a single receiving device it is known as a ____ transmission.&#10;A) multicast&#10;B) unicast&#10;C) broadcast&#10;D) linecast

Accepted Answer

A unicast transmission is intended for a single receiving device. Multicast is intended for a group of devices and broadcast is intended for all devices on the network. There is no such thing as a linecast transmission.

Question 9

____ is the practice of dividing the network into smaller units.&#10;A) Switching&#10;B) Segmentation&#10;C) VLANs&#10;D) Filtering

Accepted Answer

Segmentation is the practice of dividing the network into smaller units, such as subnets, to improve network performance, security, and manageability. Switching refers to the process of forwarding network packets between network segments based on MAC addresses. VLANs (Virtual LANs) allow network administrators to logically divide a single physical network into multiple virtual networks, while filtering involves the process of blocking or allowing network traffic based on specified criteria.

Question 10

Sending a packet to all network devices is called a ____ transmission.&#10;A) unicast&#10;B) multicast&#10;C) broadcast&#10;D) singlecast

Accepted Answer

Broadcasting sends a message to all devices on the network, regardless of address. Unicasting sends a message from one device directly to another device, while multicasting sends a message to a group of selected devices. Singlecasting is not a valid term in networking.
