5	What must be configured to establish a serial link between two routers that are directly connected? a clock rate on the DTE interface a no clock rate command on the DTE interface no configuration is required a clock rate on the DCE interface
6	Select the commands necessary to remove any existing configuration on a router. (Choose two.) delete flash erase startup-config erase running-config restart reload delete NVRAM
7	Why is it important to create standards for network consistency? (Choose three.) reduces network complexity increases unplanned downtime limits unplanned downtime increases bandwidth by regulating networking performance limits events that may impact network performance
8	Which are valid router prompts? (Choose three.) Router(privileged)# Router(config)# Router(command)# Router(config-router)# Router(config-if)# Router(exec)#
9	Which statements are true regarding the recommended use of login banners? (Choose two.) They should be used to display information regarding system changes or maintenance. They should be used to display warnings to unauthorized users. They should be used to display welcome messages prior to login. They should be seen only by system administrators. They should provide confirmation of incoming IP addresses.
10	What is the default state of the interfaces on a router? up, line protocol down down, line protocol down adminstratively down, line protocol down up, line protocol up
11	What will be the response from the router after the command, "router(config)# hostname portsmouth" is entered? portsmouth# portsmouth(config)# invalid input detected router(config-host)# hostname = portsmouth portsmouth# ? command not recognized router(config)#
12	Select the recommended locations to save a running-config file. (Choose three.) all network hosts network server floppy disk TFTP server server that is not on the network
13	What is the effect of the command ip host HQ 192.1.1.1? permits a ping to 192.1.1.1 with the command ping HQ assigns the description HQ to the interface with the ip address 192.1.1.1 renames the router as HQ defines a static route to the host 192.1.1.1 configures the remote device HQ with the ip address of 192.1.1.1
14	A network administrator wants to assure that any password that permits access to the privileged EXEC mode is not shown in plain text in the configuration files. Which commands will accomplish this task? (Choose two.) Router(config)#enable cisco secret Router(config)#enable cisco Router(config)#service password-encryption Router(config)#enable secret cisco Router(config)#encrypt-all cisco Router(config)#service encryption-password
15	Which command turns on a router interface? Router(config-if)# enable Router(config-if)# no down Router(config-if)# s0 active Router(config-if)# interface up Router(config-if)# no shutdown
16	Router names are associated with IP addresses. What is the name of the table that is created by this association? IP table SAP table ARP table MAC table HOST table RARP table
17	A telnet session can be established when using the IP address of a router but not the name of the router. Which of the following is the most likely cause of the problem? an incorrect host table entry an incorrect ARP table entry an incorrect routing table entry an incorrect protocol configured an incorrect subnet mask
18	The serial connection shown in the graphic needs to be configured. Which configuration commands must be made on the Sydney router to establish connectivity with the Melbourne site? (Choose three.) Sydney(config-if)# ip address 201.100.53.2 255.255.255.0 Sydney(config-if)# no shutdown Sydney(config-if)# ip address 201.100.53.1 255.255.255.224 Sydney(config-if)# clock rate 56000 Sydney(config-if)# ip host Melbourne 201.100.53.2
19	An IP network is to be added to a router Ethernet interface. What steps must be performed to configure this interface to allow connectivity to the hosts on this LAN? (Choose two.) Enter the command no shutdown. A password must be set on the interface. The interface DCE clock rate must be set. The interface must be configured for virtual terminal access. The interface must be configured with an IP address and subnet mask. The router must be put in setup mode in order for the interface to be configured.
20	Select the interface descriptions that provide the most appropriate information. (Choose two.) circuit number host IP address telnet password number of hops between routers purpose and location of the interface
21	What are the default settings for a serial interface? (Choose three.) DTE DCE shutdown no IP address clock rate 56000 encapsulation ARPA
22	Select the correct sequence of commands that will configure "Engineering LAN" as the interface description on the Ethernet0 interface. Router# configure terminal Router(config)# interface e0 description Engineering LAN Router# configure terminal Router(config)# interface e0 Router(config-if)# description Engineering LAN Router# configure terminal Router(config)# interface e0 Router(config-if)# interface description Engineering LAN Router# configure terminal Router(config)# description Engineering LAN
