Q: Which of these protocols is used by DNS? or Q: Of these protocols, which one does DNS use? User Datagram Protocol (UDP) Hypertext Transfer Protocol (HTTP) Dynamic Host Configuration Protocol (DHCP) IP (Internet Protocol) Explanation: UDP, which stands for User Datagram Protocol, is the protocol that the Domain Name System (DNS) uses. Because it is a connectionless protocol, the Domain Name System (DNS) generally utilizes UDP on port 53 for its queries and replies. This is because UDP is quicker than other protocols for the brief queries and responses that are normally necessary for DNS lookups. On the other hand, Domain Name System (DNS) may also employ Transmission Control Protocol (TCP) for certain jobs that need more reliable transmission. These duties include zone transfers and answers that exceed the maximum size of a UDP packet. However, the most important protocol is still UDP.

Which Transmission Control Protocol (TCP) flag will be used? or Q: You are transmitting a little bit of data, and you need a quick response from the listening software. Which TCP (Transmission Control Protocol) flag is going to be utilized? PSH RST ACK URG Explanation: The PSH flag instructs the receiving end to quickly push the data to the application layer rather than buffering it. This ensures that the information is handled on time.

Q: If the checksum doesn’t compute for a packet sent at the Internet Protocol (IP) level, what will happen to the data? or Q: What would happen to the data if the checksum for a packet delivered at the Internet Protocol (IP) level is not computed?

What has occurred? or Q: Two devices establish a Transmission Control Protocol (TCP) connection and confirm that they are speaking the same protocol. What has happened? Two-way handshake Three-way handshake Four-way handshake Handwaving Explanation: A three-way handshake takes place when a connection is created using Transmission Control Protocol (TCP) and two devices make sure that they are communicating using the same protocol.

Q: Which field in the TCP header provides the information for the receiving network device to understand where the actual data payload begins? or Q: Which TCP header field contains the information needed by the receiving network device to determine the start of the actual data payload? Sequence number Checksum Data offset Acknowledgement number Explanation: The Data Offset, which is often referred to as the Header Length, is a parameter that sets the size of the TCP header. This parameter enables the receiving device to ascertain the point at which the header finishes and the real data payload begins.

Q: Nodes on a network have the ability to direct traffic toward many different receiving services. What provides this ability in the transport layer? or Q: Traffic on a network may be routed by nodes to a variety of receiving services. What in the transport layer provide this capability?

Distance-vector Exterior gateway Link state Interior gateway Explanation: In particular, the Border Gateway Protocol (BGP) is the outside gateway protocol that is used the most often now. The Border Gateway Protocol (BGP) is an important component of inter-domain routing since it is meant to facilitate the exchange of routing information across various autonomous systems on the Internet.

Q: Link state routing protocols are newer and they require… or Q: The most recent link state routing schemes call for Less memory and less processing power Modern encryption standards More memory and more processing power Manual updating Explanation: This occurs because link state protocols are responsible for maintaining a comprehensive map of the topology of the network. This map is created by storing specific information on the state of each link in the network. When employing methods like Dijkstra’s, this necessitates an increase in both memory and computing capacity to effectively manage and calculate the shortest route to each destination.

Q: A router is performing basic routing functions. What is the first step in the transmission of a packet? or Q: Basic routing operations are carried out via a router. What is the first stage of a packet’s transmission? The router examines the destination IP of this packet. Check the routing table. A router receives a packet of data. Sent an ARP response. Explanation: Once the packet has been received, the router will next check its routing table and study the destination IP address of the packet to find the next hop that is most suitable for forwarding the packet. If it is required, the router may additionally transmit an ARP response to resolve the IP address of the next hop to a unique MAC address.

Q: What does CIDR stand for? or Q: What is the acronym for CIDR? Clear Inter-Developer Relations Classic Intra-Demo Ratings Costless Inter-Data Routing Classless Inter-Domain Routing Explanation: Classless Inter-Domain Routing is what CIDR is an abbreviation for. The former class-based system of IP address allocation has been replaced by this technique, which is a different approach to the allocation of IP addresses and the routing of IP packets. Through the use of variable-length subnet masks (VLSM), CIDR makes it possible to make more effective use of IP addresses and to improve the scalability of routing.

Q: Why do entries in a local Address Resolution Protocol (ARP) table expire after a short amount of time? or Q: What causes entries in a local Address Resolution Protocol (ARP) table to vanish quickly? To account for network changes To keep space in the table It only needs to be used one time It will use too much memory Explanation: With time, network configurations and devices may change. The Address Resolution Protocol (ARP) table has to be updated to reflect any changes that occur inside the network, such as when an IP address is transferred to a new device or when devices leave the network. To ensure that the ARP table is always correct and up to date, expiring entries are helpful.

Q: In a Class A address, the possible values for the first octet are: or Q: The following are potential values for the first octet of a Class A address: 255 through 420 128 through 199 0 through 127 0 through 255 Explanation: The range of potential values for the first octet of an IP address that is classified as Class A is from 0 to 127. Class A addresses are established by setting the first bit of the first octet to zero, which restricts the range of the first octet to the range of 0 to 127.
