  • 1. Cisco Discovery - DRSEnt Module 4 - V.4 in english.Q.1 A network engineer is implementing a network design using VLSM for network 192.168.1.0/24. Aftersubnetting the network, the engineer has decided to take one of the subnets, 192.168.1.16/28 andsubnet it further to provide for point-to-point serial link addresses. What is the maximum number ofsubnets that can be created from the 192.168.1.16/28 subnet for serial connections? 1 2 4 6 8 16Q.2 When running NAT, what is the purpose of address overloading? limit the number of hosts that can connect to the WAN allow multiple inside addresses to share a single global address force hosts to wait for an available address allow an outside host to share inside global addressesQ.3 What two advantages does CIDR provide to a network? (Choose two.) reduced routing table size dynamic address assignment automatic route redistribution reduced routing update traffic automatic summarization at classful boundariesQ.4 How does a router keep track of which inside local address is used when NAT overload isconfigured?
  • 2. The router adds an additional bit to the source IP address and maintains a separate table. The router modifies the QoS field. The router uses TCP or UDP port numbers. The router uses a manual entry that is created and maintained in the database of the router.Q.5 What is a characteristic of a classful routing protocol on the network? All subnets are seen by all routers. CIDR addresses are advertised. A subnet can be further subnetted down and advertised correctly. Updates received by a router in a different major network have the default mask applied.Q.6 Refer to the exhibit. Which address is an inside global address? 10.1.1.1 10.1.1.2 198.18.1.55 64.100.0.1Q.7 Refer to the exhibit. All networks that are shown have a /24 prefix. Assuming that all routes havebeen discovered by all routers in the network, which address will successfully summarize only thenetworks that are shown? 192.168.8.0/21 192.168.8.0/24 192.168.16.0/20 192.168.16.0/21 192.168.16.0/24
  • 3. Q.8 What is the CIDR prefix designation that summarizes the entire reserved Class B RFC 1918 internaladdress range? /4 /8 /12 /16 /20Q.9 Which NAT term refers to the IP address of your inside host as it appears to the outside network? inside global IP address outside global IP address inside local IP address outside local IP addressQ.10 A network administrator is asked to design a new addressing scheme for a corporate network.Presently, there are 500 users at the head office, 200 users at sales, 425 at manufacturing, and 50 at theresearch site. Which statement defines the correct VLSM addressing map with minimal waste using the172.16.0.0/16 network? 172.16.0.0/20 head office 172.16.1.0/21 manufacturing 172.16.1.0/22 sales 172.16.3.0/26 research 172.16.48.0/19 head office 172.16.16.0/20 manufacturing 172.16.48.128 sales 172.16.48.0/26 research 172.16.2.0/23 head office 172.16.4.0/23 manufacturing 172.16.6.0/24 sales 172.16.7.0/26 research
  • 4. 172.16.2.0/22 head office 172.16.3.0/23 manufacturing 172.16.4.0/26 sales 172.16.4.128/25 researchQ.11 A company using a Class B IP addressing scheme needs as many as 100 subnetworks. Assumingthat variable length subnetting is not used and all subnets require at least 300 hosts, what subnet maskis appropriate to use? 255.255.0.0 255.255.240.0 255.255.254.0 255.255.255.0 255.255.255.128 255.255.255.192Q.12 Host A in the exhibit is assigned the IP address 10.118.197.55/20. How many more network devicescan be added to this same subnetwork? 253 509 1021 2045 4093Q.13 Refer to the exhibit. RIP version 2 is configured as the network routing protocol and all of thedefault parameters remain the same. Which update is sent from R2 to R3 about the 10.16.1.0/24network connected to R1? 10.16.0.0/16 10.0.0.0/24
  • 5. 10.0.0.0/8 10.16.1.0/24Q.14 What range of networks are summarized by the address and mask, 192.168.32.0/19? 192.168.0.0/24 - 192.168.32.0/24 192.168.0.0/24 - 192.168.31.0/24 192.168.32.0/24 – 192.168.64.0/24 192.168.32.0/24 – 192.168.63.0/24Q.15 Refer to the exhibit. Based on the output of the show ip nat translations command, which kind ofaddress translation is in effect on this router? static public overload privateQ.16 How many addresses will be available for dynamic NAT translation when a router is configuredwith the following commands?Router(config)#ip nat pool TAME 209.165.201.23 209.165.201.30 netmask 255.255.255.224Router(config)#ip nat inside source list 9 pool TAME 7 8 9 10 24 31
  • 6. Q.17 Refer to the exhibit. Which two IP addresses could be assigned to the hosts that are shown in theexhibit? (Choose two.) 192.168.65.31 192.168.65.32 192.168.65.35 192.168.65.60 192.168.65.63 192.168.65.64Q.18 What are the network and broadcast addresses for host 192.168.100.130/27? (Choose two.) network 192.168.100.0 network 192.168.100.128 network 192.168.100.130 broadcast 192.168.100.157 broadcast 192.168.100.159 broadcast 192.168.100.255Q.19 Refer to the exhibit.
