Take Assessment Take Assessment - DRSEnt Final - CCNA Discovery: Introducing Routing and Switching in the Enterprise (Version 4.0) Time Remaining: 16 A company is trying to decide whether to use a PVC or an SVC for the company WAN connection. Which statement best describes a benefit of using a PVC? A PVC is dynamically established between two points when a router requests a transmission. A PVC eliminates the need for call setup and clearing for each transmission session. A PVC is best suited for small companies with sporadic data flows. A PVC does not require preconfiguration by a service provider. 17 Refer to the exhibit. In what sequence (from first to last) does an OSPF router check the parameters listed when selecting the DR? C, B, A, D D, C, B, A A, B, C, D A, C, B, D B, C, A, D 18 Which two addresses are RFC 1918 private addresses? (Choose two.) 10.192.32.67 64.10.10.2 172.31.220.7 172.168.12.1 192.16.0.1 19 Which statement is true about the difference between CHAP and PAP in PPP authentication? PAP and CHAP provide equivalent protection against replay attacks. PAP sends the password encrypted and CHAP does not send the password at all. PAP uses a two-way handshake method and CHAP uses a three-way handshake method. PAP sends the password once and CHAP sends the password repeatedly until acknowledgement of authentication is received. 20 Refer to the exhibit. A network administrator noticed that the VLAN configuration changes at SW2 did not propagate to SW3. On the basis of the partial output of the show vtp status command, what is the possible cause of the problem? VTP V2 mode is disabled. SW3 is configured as transparent mode. The number of existing VLANs does not match. The configuration revision number does not match. 21 Which statement best describes an extranet? An extranet is a public access network. An extranet is a remote access network. An extranet is a restricted private network for internal users only. An extranet is a private network that allows controlled access to external users. 22 Refer to the exhibit. R1 and R2 are connected via serial interfaces. Both interfaces show that there is Layer 2 connectivity between them. The administrator verifies that CDP is operational; however, pings between the two interfaces are unsuccessful. What is the cause of this connectivity problem? no set loopback incorrect subnet mask on R2 incompatible bandwidth incorrect IP address on R1 incompatible encapsulation 23 An administrator is configuring a new router to permit out-of-band management access. Which set of commands will allow the required login using a password of cisco? Router(config)# line vty 0 4 Router(config-line)# password manage Router(config-line)# exit Router(config)# enable password cisco Router(config)# line vty 0 4 Router(config-line)# password cisco Router(config-line)# login Router(config)# line console 0 Router(config-line)# password cisco Router(config-line)# login Router(config)# line console 0 Router(config-line)# password cisco Router(config-line)# exit Router(config)# service password-encryption 24 Refer to the exhibit. Which two statements are correct about the VTP configuration on S2? (Choose two.) The default mode is used. The default domain name is used. A new client mode switch in the CISCO domain would receive updates from S2. S2 would not update a new client mode switch whose VTP revision number is 3. S2 will share VLAN database updates with a switch that is configured with VTP version 1. 25 When MD5 authentication is used for OSPF routing protocol authentication, what two facts are known about the key? (Choose two.) The key passes between routers in plain text. The key is used to help generate an encrypted number for authentication. The key passes between routers in encrypted form. The key is never transmitted. The key can be captured by using a packet sniffer. 26 Which routing protocol uses RTP for reliable route update delivery? RIPv1 RIPv2 OSPF EIGRP 27 Refer to the exhibit. OSPF has been configured on routers R1 and R2. The routing tables reveal that no OSPF routes are being exchanged between the two routers. What could cause this problem? The network type must be changed on R1. The OSPF cost is too high for updates to occur. The process ID on R2 needs to be changed to 2. The timer intervals on the routers do not match. 28 Refer to the exhibit. The network administrator configured the routers using the displayed commands, but the network fails to converge. What can the network administrator do to solve this problem? Issue the network commands correctly on both routers. Configure the wildcard masks correctly on both routers. Issue the no auto-summary command. Configure both routers with different autonomous numbers. 29 Refer to the exhibit. Which numbers correctly identify the features for RIPv1 and RIPv2? 2, 4, 6 3, 5, 9 4, 8, 9 5, 6, 7 30 Refer to the exhibit. Which router or routers would be considered OSPF ABRs? R1 R6, R8 R2, R6, R8 R2, R3, R4, R5 R8, R9, R10, R11 Showing 2 of 4 Close Window All contents copyright 1992-2011 Cisco Systems, Inc. Privacy Statement and Trademarks.
