Network layer<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The Network layer, Layer 3 of the OSI model, provides logical addressing and routing between different networks. IPv4 and IPv6 operate at this layer, and routers examine destination IP addresses to determine where packets should be forwarded. The Physical layer handles transmission of raw bits, while the Data Link layer provides functions such as Ethernet framing and MAC addressing. The Transport layer provides end-to-end communication using protocols such as TCP and UDP.<\/span><\/p>\n<p><b>Question 2.<\/b><\/p>\n<p><b>Which protocol provides reliable, connection-oriented transport and uses acknowledgments and retransmissions?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> UDP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> TCP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> ARP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> ICMP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. TCP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">TCP is a connection-oriented Transport layer protocol designed to provide reliable delivery. It uses sequence numbers, acknowledgments, retransmissions, flow control, and connection establishment mechanisms to help ensure data reaches the destination correctly and in the proper order. UDP provides connectionless transport with less overhead but does not provide the same built-in reliability mechanisms. ARP resolves IPv4 addresses to MAC addresses, while ICMP supports network control and diagnostic functions.<\/span><\/p>\n<p><b>Question 3.<\/b><\/p>\n<p><b>Which protocol is used by an IPv4 host to discover the MAC address associated with another local IPv4 address?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> DHCP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> ARP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> FTP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. ARP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">ARP, or Address Resolution Protocol, maps an IPv4 address to a MAC address on a local network. Before sending an Ethernet frame to a local destination, a host may broadcast an ARP request asking which device owns a particular IP address. The destination responds with its MAC address, which can then be stored temporarily in the ARP table. DNS resolves names to IP addresses, DHCP provides network configuration, and FTP is used for file transfer.<\/span><\/p>\n<p><b>Question 4.<\/b><\/p>\n<p><b>Which device primarily forwards Ethernet frames based on destination MAC addresses?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Router<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Firewall<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> Modem<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Switch**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Switch<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">An Ethernet switch forwards frames primarily according to MAC addresses. It learns source MAC addresses from incoming frames and records them in a MAC address table associated with switch ports. When the destination address is known, the switch forwards the frame through the appropriate port. Routers primarily forward packets based on IP addresses. Although modern network devices may provide several functions, MAC-based forwarding is the fundamental Layer 2 switching operation.<\/span><\/p>\n<p><b>Question 5.<\/b><\/p>\n<p><b>Which IPv4 address is part of a private address range?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 10.20.30.40<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> 8.8.8.8<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> 1.1.1.1<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> 203.0.113.10<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. 10.20.30.40<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">The 10.0.0.0\/8 network is one of the IPv4 ranges reserved for private addressing. The other private ranges are 172.16.0.0\/12 and 192.168.0.0\/16. Private addresses are commonly used inside enterprise and home networks and are not normally routed directly across the public internet. Network Address Translation can allow privately addressed devices to communicate with external networks using one or more public addresses.<\/span><\/p>\n<p><b>Question 6.<\/b><\/p>\n<p><b>Which subnet mask corresponds to an IPv4 \/24 prefix length?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 255.255.0.0<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> 255.255.255.0<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> 255.255.255.128<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> 255.255.255.252<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. 255.255.255.0<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A \/24 prefix means that the first 24 bits of the subnet mask are set to 1. In dotted-decimal notation, this is 255.255.255.0. A \/24 network therefore leaves eight bits available for host addressing. In a traditional IPv4 subnet, this produces 256 total addresses, with the network and broadcast addresses normally unavailable for assignment to standard host interfaces, leaving 254 usable host addresses.<\/span><\/p>\n<p><b>Question 7.<\/b><\/p>\n<p><b>What is the network address for host 192.168.10.25 with subnet mask 255.255.255.0?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 192.168.10.25<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> 192.168.10.255<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> 192.168.10.0<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> 192.168.0.0<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. 192.168.10.0<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">With a 255.255.255.0, or \/24, subnet mask, the first three octets identify the network and the final octet identifies the host. Therefore, the address 192.168.10.25 belongs to network 192.168.10.0\/24. The address 192.168.10.255 is the broadcast address for this subnet, while addresses between the network and broadcast addresses can normally be assigned to hosts.<\/span><\/p>\n<p><b>Question 8.<\/b><\/p>\n<p><b>Which IPv4 address represents the loopback address commonly used to test the local TCP\/IP stack?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> 0.0.0.0<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> 255.255.255.255<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> 169.254.1.1<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> 127.0.0.1**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. 127.0.0.1<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">127.0.0.1 is the commonly used IPv4 loopback address. Traffic sent to this address remains on the local device, making it useful for testing whether the local TCP\/IP software stack is functioning. Loopback testing does not verify the physical network interface, cable, switch, or connectivity to other devices. The broader 127.0.0.0\/8 range is reserved for loopback purposes.<\/span><\/p>\n<p><b>Question 9.<\/b><\/p>\n<p><b>Which protocol is commonly used by the ping utility to test IP reachability?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> ICMP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> HTTP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> ARP only<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> FTP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. ICMP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Ping commonly uses ICMP Echo Request and Echo Reply messages to test whether an IP destination responds. It can help determine whether basic network-layer connectivity exists and can provide round-trip timing information. However, a failed ping does not always prove that a host is unavailable because firewalls or security policies may block ICMP messages. HTTP and FTP are application protocols, while ARP is used for local IPv4 address resolution.<\/span><\/p>\n<p><b>Question 10.<\/b><\/p>\n<p><b>Which protocol automatically assigns IP configuration information to network clients?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> DNS<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> DHCP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> SNMP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> SSH<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 2. DHCP<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">DHCP, or Dynamic Host Configuration Protocol, automatically supplies network clients with configuration such as an IP address, subnet mask, default gateway, and DNS server information. This simplifies network administration and reduces errors associated with manual address configuration. DNS performs name resolution, SNMP supports network monitoring and management, and SSH provides secure remote command-line access.<\/span><\/p>\n<p><b>Question 11.<\/b><\/p>\n<p><b>Which protocol translates human-readable domain names into IP addresses?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> ARP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> FTP<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> DNS<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> ICMP<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 3. DNS<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">DNS, or Domain Name System, resolves names such as hostnames and domain names into IP addresses. This allows users to access network resources using memorable names instead of numerical addresses. DNS uses a distributed hierarchical architecture involving resolvers and authoritative servers. ARP resolves IPv4 addresses to local MAC addresses, FTP transfers files, and ICMP is used for network control and diagnostic messaging.<\/span><\/p>\n<p><b>Question 12.<\/b><\/p>\n<p><b>Which address does an Ethernet switch primarily learn when receiving a frame on one of its ports?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> Destination IP address<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> Default gateway<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> DNS server address<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> Source MAC address**<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 4. Source MAC address<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">A switch learns the source MAC address of frames arriving on its interfaces and associates each learned address with the incoming port in its MAC address table. This allows the switch to make efficient forwarding decisions for future frames. When a destination MAC address is unknown, the switch may flood the frame through relevant ports in the VLAN. Learning source addresses is therefore fundamental to Ethernet switching.<\/span><\/p>\n<p><b>Question 13.<\/b><\/p>\n<p><b>Which Huawei VRP command moves a user from the user view into the system view?<\/b><\/p>\n<ol>\n<li><b><\/b><span style=\"font-weight: 400;\"> system-view<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>2.<\/b><span style=\"font-weight: 400;\"> enable<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>3.<\/b><span style=\"font-weight: 400;\"> configure terminal<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><b>4.<\/b><span style=\"font-weight: 400;\"> administrator-mode<\/span><\/li>\n<\/ol>\n<p><b>Correct Answer: 1. system-view<\/b><\/p>\n<p><b>Explanation:<\/b><\/p>\n<p><span style=\"font-weight: 400;\">On Huawei devices running VRP, the <\/span><span style=\"font-weight: 400;\">system-view<\/span><span style=\"font-weight: 400;\"> command enters the system view, where administrators can perform device-wide configuration.
