Section 2.1 Demonstrate your acquired knowledge about the Characteristics of Routing Technologies. This will demonstrate your proficiency for section 2.1 of the Network+ 10-009 objectives. 1 / 25 Which type of NAT uses a pool of public IP addresses for mapping private IPs dynamically? Static NAT Dynamic NAT PAT DNAT 2 / 25 Which of the following best describes the function of a metric in a routing protocol? It determines the amount of public IP addresses used. It identifies the owner of the route. It quantifies the cost or preference of a route. It encrypts the route data for security. 3 / 25 Which routing protocol uses Diffusing Update Algorithm (DUAL) for route calculation? BGP OSPF RIP EIGRP 4 / 25 Which of the following best describes OSPF's area hierarchy? One flat area with no internal structure Divides the network into areas, with Area 0 as the backbone Divides networks based on administrative domains All areas are isolated and do not connect 5 / 25 Which routing protocol uses path vector logic and is the backbone of the Internet? OSPF BGP RIP EIGRP 6 / 25 On a router, how are subinterfaces typically configured to separate traffic by VLAN? By assigning each subinterface a different subnet mask Using GRE tunnels By tagging VLANs with IEEE 802.1Q By configuring static routing rules 7 / 25 What is a subinterface commonly used for in a router configuration? Encrypt routing tables Create multiple virtual interfaces on a single physical interface Act as a backup router Provide NAT services 8 / 25 Which FHRP allows multiple routers to actively share traffic load? HSRP VRRP GLBP OSPF 9 / 25 Which FHRP is Cisco proprietary and provides active-passive gateway redundancy? VRRP GLBP HSRP BGP 10 / 25 Which of the following protocols is NOT an FHRP? HSRP VRRP GLBP EIGRP 11 / 25 In an FHRP setup, what is the role of the virtual IP address? To provide encryption to network traffic To act as a backup DNS To allow hosts to use a single gateway address regardless of which router is active To provide DHCP relay services 12 / 25 Which of the following protocols provides gateway redundancy using a shared virtual IP address? OSPF NAT FHRP BGP 13 / 25 What is the primary reason for using NAT in a network? Increase routing speed Avoid firewall inspection Conserve public IP addresses Improve DNS resolution 14 / 25 In traditional NAT, how many internal private IPs can be mapped to a single public IP address without PAT? 1 2 5 Unlimited 15 / 25 Which form of address translation maps multiple private IPs to a single public IP using port numbers? Static NAT Dynamic NAT PAT DNS forwarding 16 / 25 Which component of route selection helps break ties when multiple routes have the same prefix length and administrative distance? Random selection Cost Metric Hop count 17 / 25 What does a more specific prefix length in a route (e.g., /27 vs /24) indicate? A less specific route A route with a higher administrative distance A route to a broader range of addresses A more specific match that will be preferred in routing decisions 18 / 25 Which route will be preferred by a router: one with administrative distance 110 and metric 10, or one with administrative distance 90 and metric 20? The one with AD 110 and metric 10 The one with AD 90 and metric 20 Both are equal Neither, it chooses randomly 19 / 25 In route selection, what is the purpose of administrative distance? Measures the bandwidth of the link Indicates the security of the route Ranks the trustworthiness of the source of the route Counts the number of hops in the path 20 / 25 Which routing protocol supports classless routing and VLSM? RIPv1 BGP OSPF IGRP 21 / 25 Which of the following is true about EIGRP? It uses the Dijkstra algorithm It is a link-state routing protocol It is Cisco proprietary and uses a composite metric It is commonly used for routing between ISPs 22 / 25 What metric does OSPF primarily use to determine the best route? Hop count Bandwidth Delay Cost 23 / 25 Which routing protocol is classified as an exterior gateway protocol (EGP)? OSPF EIGRP RIP BGP 24 / 25 Which scenario is most appropriate for using static routing? A large enterprise with multiple routers and links A rapidly changing network topology A small branch office with a single path to the main network A multinational network that spans continents 25 / 25 What is one major advantage of static routing over dynamic routing? Automatically adapts to network changes Consumes less bandwidth and CPU resources Automatically finds the shortest path Scales easily in large networks Your score is 0% Restart quiz Return to CompTia N+ 10-009 Objectives
