Which of the following routing protocols uses relative link cost as the metric?a. BGPb. EIGRPc. OSPFd. RIP
The routing protocol that uses relative link cost as the metric is OSPF (Open Shortest Path First).
OSPF is a link-state routing protocol that calculates the shortest path to a destination using a metric called the cost. The cost of a path is calculated by adding up the costs of the links along that path. The cost of a link is determined by the bandwidth of the link, so higher bandwidth links have a lower cost than lower bandwidth links.
In OSPF, the cost of a link is used as a metric to determine the best path to a destination. The lower the cost, the better the path. OSPF uses a hierarchical network structure and divides the network into areas, with each area having its own link-state database.
BGP (Border Gateway Protocol) is a path-vector routing protocol that is used to exchange routing information between different autonomous systems on the Internet. BGP uses the AS path as the metric to determine the best path to a destination.
EIGRP (Enhanced Interior Gateway Routing Protocol) is a distance-vector routing protocol that uses bandwidth, delay, reliability, and load as the metrics to determine the best path to a destination.
RIP (Routing Information Protocol) is also a distance-vector routing protocol that uses hop count as the metric to determine the best path to a destination.

to make a copy of the original database for use if data is lost or becomes corrupt
To make a copy of the original database for use if data is lost or becomes corrupt, a database backup must be created.
A backup is essentially a snapshot of the current state of the database at a particular point in time, and it can be used to restore the database to that state in case of data loss or corruption. There are several types of database backups, including full backups (which copy all data in the database), differential backups (which copy only data that has changed since the last full backup), and incremental backups (which copy only data that has changed since the last backup of any type). Database backups can be stored on external media or in the cloud, and they should be performed regularly to ensure that a recent backup is always available in case of emergency.

What type of function can be used to determine whether a number is even or odd? A. even. B. Boolean C. math. D. odd.
Determining whether a number is even or odd is a basic operation in mathematics. There are various ways to approach this problem, but one common method is to use a function. In this answer, we will discuss the type of function that can be used to determine whether a number is even or odd.
The function that is commonly used to determine whether a number is even or odd is called the modulo function, denoted by the symbol "%". The modulo function returns the remainder of a division operation between two numbers. For example, 5 % 2 returns 1, which is the remainder when 5 is divided by 2. When a number is divided by 2, there are two possible remainders: 0 and 1. If the remainder is 0, the number is even, and if the remainder is 1, the number is odd. Therefore, to determine whether a number is even or odd using the modulo function, we simply need to divide the number by 2 and check the remainder. If the remainder is 0, the number is even, and if the remainder is 1, the number is odd.
In conclusion, the function that can be used to determine whether a number is even or odd is the modulo function, which returns the remainder of a division operation. By dividing a number by 2 and checking the remainder, we can determine whether the number is even or odd. Therefore, the correct answer to the question is D, odd.

When a local DNS server queries a TLD server, what kind of query does it send?
a. Recursive
b. Iterative
c. Distributed
When a local DNS server queries a TLD (Top-Level Domain) server, it sends an iterative query. In an iterative query, the local DNS server sends a request to the TLD server for the IP address of the domain name it is trying to resolve.
The TLD server responds with either the IP address or the IP address of the authoritative name server for the next level domain name. The local DNS server then sends a query to the authoritative name server for the next level domain name and continues this process until it receives the IP address of the requested domain name.
In contrast, a recursive query is when the local DNS server sends a request to another DNS server to resolve a domain name and expects a complete response with the IP address of the requested domain name. The recursive query is useful for clients that do not have a local cache of domain name information and need to resolve a domain name quickly.

Actually, a named constant is not just a variable. It is a variable that is assigned a value once and cannot be changed during the program's execution.
A constant is a variable that is assigned a value once and remains constant throughout the program's execution. It is used to store values that should not be changed during the program's execution, such as mathematical constants, physical constants, and other values that need to be used repeatedly in the program. Once a constant is assigned a value, it cannot be changed during the program's execution, which means that the program cannot accidentally or intentionally modify its value.
Unlike variables, constants are not meant to change during the program's execution, and they are declared using the const keyword. Any attempt to modify a constant's value will result in a compiler error.

TCP/IP is considered the standard protocol for the Internet and has played a significant role in the growth and development of the internet as we know it today.

Which of the following are protocols that you find at the application layer of the OSI model? a. TCP and UDP b. IP and ICMP c. HTTP and FTP d. Ethernet and Token Ring
The application layer of the OSI model deals with the communication protocols that enable user applications to access the network services. Among the given options, the protocols that are commonly found at the application layer are c. HTTP and FTP. HTTP (Hypertext Transfer Protocol) is used to transfer web pages over the internet and is the foundation of the World Wide Web.
FTP (File Transfer Protocol) is used for transferring files between servers and clients over the internet. TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are transport layer protocols that provide communication between devices on a network. They ensure that data is delivered reliably and accurately from one device to another. IP (Internet Protocol) and ICMP (Internet Control Message Protocol) are network layer protocols that provide routing and addressing capabilities in the network. IP is responsible for delivering packets of data from one network device to another while ICMP is used for error reporting and network diagnostics. Ethernet and Token Ring are data link layer protocols that provide the physical connection between devices on a network. They deal with the transmission of data between devices on the same network segment. In conclusion, HTTP and FTP are the protocols that are commonly found at the application layer of the OSI model.
