1. What are the valid Host ID's for 222.37.2.50 /24 ? A.) 222.37.2.48 - 222.37.2.66 B.) 222.37.2.49 - 222.37.2.62 C.) 222.37.2.0 - 222.37.2.255 D.) 222.37.0.0 - 222.37.255.254 E.) 222.37.2.1 - 222.37.2.254
D
2. Which commands listed below will move you from interface configuration mode back to global configuration mode? A.) CTL+Z B.) CTL+F C.) exit D.) global E.) config t
C CTRL-Z and CTRL-C will abort you back to the root. Exit goes back one level.
3. You have a Unix server running the TFTP Daemon. What is the command to load a configuration file from the TFTP server into the routers RAM? A.) copy tftp ram B.) copy tftp running-config C.) read tftp D.) copy tftp startup-config E.) copy tftp nvram
B Remember RAM = RUNNING-CONFIG. All changes to RAM are immediate!
4. Given the following static route command, ip route 3.3.3.0 255.255.255.0 4.4.4.4 125, which portion represents the next hop TCP/IP address? A.) 125 B.) 3.3.3.0 C.) 255.255.255.0 D.) route E.) 4.4.4.4
E Router(config)#ip route 3.3.3.0 255.255.255.0 ? A.B.C.D Forwarding router's address
5. In regards to the ISDN BRI standard, which channel is used for control? A.) E B.) Q C.) D D.) I E.) B
C B is Bearer for Data (2 channels at 64kb each). D is for Control (16kb).
6. Which Distance Vector characteristic can help to speed up convergence? A.) Inverse ARP. B.) Poison Reverse. C.) Triggered Updates. D.) Split Horizon. E.) Hold Down timers.
C Instead of waiting on a pre-set periodic interval (before sending the routing table), DV routing protocols can send triggered updates to immediately notify the neighbor routers. Hold down timers, Poison Reverse, and Split Horizon are features that are used to avoid routing loops.
7. What command would show the current configuration register settings? A.) show running-config B.) show startup-config C.) show nvram D.) show ram E.) show version F.) show ios
E For most routers the configuration register settings are: 0x2102 normal operation (parse NVRAM at startup), or 0x2142 password recovery (ignore NVRAM during startup).
8. What would the following command do?: 'Show Frame-Relay PVC' A.) Display LMI Info. B.) The command is incomplete, and would be ignored. C.) Display all configured DLCI's. D.) Debug a Frame-Relay Problem. E.) Show Virtual Links.
C The Permament Virtual Circuit (PVC) info is d
