- B.
The policy setting in the GPO linked to the domain is applied
- C.
Neither policy setting is not applied, nor is an error message generated
- D.
The policy in both GPOs defaults to Not Defined so that no conflict exists
Correct Answer
A. The policy setting in the GPO linked to the OU is appliedExplanation
When a policy is defined in a Group Policy Object (GPO) linked to an Organizational Unit (OU) and that same policy is defined with a different setting in a GPO linked to a domain, by default, the policy setting in the GPO linked to the OU is applied. This is because GPOs linked to OUs have a higher precedence than GPOs linked to the domain. Therefore, the policy setting in the GPO linked to the OU will take effect for the objects within that OU, while the policy setting in the GPO linked to the domain will be ignored in this case.Rate this question:

STP (Spanning Tree Protocol)
- C.
BGP (Border Gateway Protocol)
- D.
OSPF (Open Shortest Path First) protocol
Correct Answer
B. STP (Spanning Tree Protocol)Explanation
Switches and bridges implement the Spanning Tree Protocol (STP) to eliminate the possibility of a broadcast storm. A broadcast storm can occur when there are multiple redundant paths in a network, causing broadcast frames to continuously circulate and consume network resources. STP helps in preventing loops by creating a loop-free logical topology and selectively blocking redundant paths. This ensures that there is only one active path between any two network devices, preventing broadcast storms and maintaining network stability.Rate this question:

In IPv4 addressing, a node with an IP address of 168.34.88.29 belongs to a Class ____ network.
- A.
A
- B.
B
- C.
C
- D.
D
Correct Answer
B. BExplanation
The given IP address, 168.34.88.29, falls within the range of Class B addresses. In IPv4 addressing, the first octet of a Class B address ranges from 128 to 191, indicating that the network belongs to Class B.Rate this question:

The default subnet mask for a Class B network is ____.
- A.
255.0.0.0
- B.
255.255.0.0
- C.
255.255.255.0
- D.
255.255.255.255
Correct Answer
B. 255.255.0.0Explanation
The default subnet mask for a Class B network is 255.255.0.0. In a Class B network, the first two octets represent the network portion, while the last two octets represent the host portion. The subnet mask is used to determine the boundaries between the network and host portions. In this case, the subnet mask of 255.255.0.0 allows for a larger number of hosts compared to the other options, as it only reserves the first two octets for the network portion.Rate this question:

On an Ethenet network, a(n) ____ is the portion of a network in which collisions occur if two nodes transmit data at the same time.
- A.
Collision domain
- B.
Crash domain
- C.
Interference domain
- D.
Duplicate domain
Correct Answer
A. Collision domainExplanation
A collision domain refers to the portion of an Ethernet network where collisions occur if two nodes transmit data at the same time. In this domain, when two or more devices transmit data simultaneously, the signals collide and result in data loss or corruption. This can happen in a shared medium such as a hub or in a switch port that has multiple devices connected without VLANs. By understanding the concept of collision domains, network administrators can design and manage their networks effectively to minimize collisions and optimize network performance.Rate this question:

A ____ is a multiport connectivity device that directs data between nodes on a network
- A.
Switch
- B.
Bridge
- C.
Router
- D.
Gateway
Correct Answer
C. RouterExplanation
A router is a multiport connectivity device that directs data between nodes on a network. Unlike a switch or bridge, a router operates at the network layer (Layer 3) of the OSI model and can make intelligent routing decisions based on IP addresses. A router connects multiple networks together and determines the best path for data packets to reach their destination. It uses routing tables and protocols to efficiently direct traffic and can also perform functions such as network address translation (NAT) and firewalling. A gateway, on the other hand, is a device that connects two different types of networks, such as a local area network (LAN) to the internet.Rate this question:

In IPv4 addressing, each IP address is a unique ____ number
- A.
12-bit
- B.
32-bit
- C.
64-bit
- D.
128-bit
Correct Answer
B. 32-bitExplanation
Each IP address in IPv4 addressing is a unique 32-bit number. This means that the address is composed of 32 binary digits, which allows for a total of 4,294,967,296 unique addresses. This 32-bit structure is a fundamental characteristic of IPv4 addressing and is used to identify and locate devices on a network.Rate this question:
