2 1 What is the decimal equivalent of ? Which of the following is the EST description of a LN? virtual private network. n encrypted internet connection. n unencrypted internet connection. network over a small area. 3 Which protocol is used to map IP addresses to physical M addresses? SM/. Telnet. RP. UP. 4 How do network clients use broadcasts to facilitate M to IP address mapping? roadcasts are used for all IP address. roadcasts are not used for mapping. roadcast are used for uncached addresses. roadcast are used over WN links. 5 In a RIPv2 network, which algorithm does RIP use to calculate the EST path between networks? ellmann-ford. iffie-hellman. UL. ijkstra. Page 2 of 6 opyright S 2017 S Level 4 ertificate in Network Principles Specimen Paper

3 6 byte is a combination of how many bits? customer has a lass address allocation of and wishes to further divide this into 16 subnets for use across departments. What subnet mask should be used to achieve this? Which dynamic routing protocol uses ijkstra's algorithm to calculate the route between networks? RIPv1. EIGRP. RIPv2. OSPF. 9 Which of the following would EST describe a MN? local network used to connect luetooth devices. Many LNs connected to provide global networking. Many LNs connected in the same region. local network used to connect wireless devices. 10 What service is designed to assign IP addresses to nodes on a TP/IP network during initialisation? Telnet. PING. Netstat. HP. Page 3 of 6 opyright S 2017 S Level 4 ertificate in Network Principles Specimen Paper

4 11 How does encapsulation facilitate data communication? Embeds PU from higher OSI layers into lower ones. Embeds PU from lower OSI layers into higher ones. Encrypts PU from higher OSI layers into lower ones. Encrypts PU from lower OSI layers into higher ones. 12 What is the maximum decimal number that can be represented in 8 binary bits? Why would dynamic routing be used? To increase network resilience and reduce network administration. To reduce network loading by sharing traffic equally between routers. To reduce network administration by automatically storing the routing tables onto a single server. To allow the use of VPNs in networks where the number of spare IP addresses is limited. 14 Which of the following are routing protocols? OSPF and TP. RIP and UP. TP and UP. OSPF and RIP. 15 Which port would be opened on a firewall to allow HTTP access to a web server? Page 4 of 6 opyright S 2017 S Level 4 ertificate in Network Principles Specimen Paper

5 16 network engineer monitors the company network and notices a bottleneck on the VoIP switch. Which network characteristic is affected? Quality of service. efault gateway. Security. HP. 17 What media is used to access wireless devices from a wireless access point? Infrared. Radio waves. Visible light. opper cable. 18 What is the network IP address of if the subnet mask is ? What is the maximum number of hosts allowed on subnet /22? Which of the following is a characteristic of VLSM? The same number of addresses is used in each subnet. It provides a more efficient use of addresses. The subnet mask is the same for each network. VLSM encourages wasted IP addresses on a network.
