From what location are the 1st computer instructions available on boot up?
- A.
ROM BIOS
- B.
CPU
- C.
Boot.ini
- D.
CONFIG.SYS
Correct Answer
A. ROM BIOSExplanation
The 1st computer instructions are available on boot up from the ROM BIOS. ROM BIOS stands for Read-Only Memory Basic Input/Output System, which is a firmware that is stored on a chip on the motherboard. It contains the initial instructions that the computer needs to start up and load the operating system. The ROM BIOS is responsible for performing a power-on self-test (POST), initializing hardware components, and loading the bootloader, which then loads the operating system.Rate this question:

What could cause a fixed disk error?
- A.
No-CD installed
- B.
Bad ram
- C.
Slow processor
- D.
Incorrect CMOS settings
Correct Answer
D. Incorrect CMOS settingsExplanation
Incorrect CMOS settings can cause a fixed disk error. The CMOS (Complementary Metal-Oxide-Semiconductor) settings store important information about the computer's hardware configuration. If these settings are incorrect, such as the disk configuration settings, it can lead to errors when accessing the fixed disk. This can result in the computer being unable to boot or read data from the hard drive. Therefore, incorrect CMOS settings can be a potential cause for a fixed disk error.Rate this question:

To eliminate the possibility of a broadcast storm, switches and bridges implement the ____.
- A.
RIP (Routing Information Protocol)
- B.
STP (Spanning Tree Protocol)
- C.
BGP (Border Gateway Protocol)
- D.
OSPF (Open Shortest Path First) protocol
Correct Answer
B. STP (Spanning Tree Protocol)Explanation
To eliminate the possibility of a broadcast storm, switches and bridges implement the Spanning Tree Protocol (STP). STP is a network protocol that prevents loops in Ethernet networks by creating a loop-free logical topology. It achieves this by dynamically selecting a root bridge and calculating the shortest path to reach each network segment. STP also provides redundancy by automatically blocking redundant links and activating them only if the active link fails, thus preventing broadcast storms caused by endless loops in the network.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
A node with an IP address of 168.34.88.29 belongs to a Class B network. In IPv4 addressing, the first octet of an IP address is used to determine the class of the network. Class B networks have a range of IP addresses from 128.0.0.0 to 191.255.255.255, with the first two octets used to identify the network and the last two octets used to identify the host. The given IP address falls within this range, indicating that it belongs to a Class B network.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 are used to identify the network, and the last two octets are used to identify the hosts. The subnet mask 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 and the remaining two octets for the hosts.Rate this question:

Correct Answer
C. RouterExplanation
A router is a multiport connectivity device that directs data between nodes on a network. Routers use routing tables to determine the best path for data packets to travel from one network to another. They can connect multiple networks together and are responsible for forwarding data packets based on their destination IP addresses. Unlike switches and bridges, routers operate at the network layer of the OSI model and can connect networks using different protocols. Gateways, on the other hand, are devices that connect networks with different architectures or protocols.Rate this question:

- A.
12-bit
- B.
32-bit
- C.
64-bit
- D.
128-bit
Correct Answer
B. 32-bitExplanation
In IPv4 addressing, each IP address is represented as a 32-bit number. This means that there are 2^32 (about 4.3 billion) unique IP addresses available in the IPv4 address space. This 32-bit number is divided into four octets (8 bits each) separated by periods, resulting in the familiar xxx.xxx.xxx.xxx format of IPv4 addresses.Rate this question:
