79. The Routing System which aimed at reducing the risk of casualties is called as______

A . RIP route 10.1.2.0/24 B . EIGRP route 10.1.2.0/24 C . RIP route 10.1.0.0/16 D . OSPF route 10.1.0.0/16 E . RIP route 10.0.0.0/16 F . OSPF route 10.1.2.0/24

A . It confines network instability to a single area of network. B . It increases the routing overhead of the network C . It supports VLSM D . It routes between Autonomous Systems. E . It allows extensive control of routing updates F . None of the above

A . Spanning Tree Protocol B . Shortest path first tree C . Link-state advertisements (LSA) D . Hold-down timers E . Split horizon F . VRRP

A .  InterVLAN routing cannot be filtered by the router. B .  The router becomes a single point of failure for the network. C .  Routers will not route STP BPDUs. D .  There is a possibility of inadequate bandwidth for each VLAN. E .  Additional overhead on the router can occur. F .  NetFlow Switching is required for InterVLAN accounting.

A . The exchange of advertisement is triggered by a change in the network. B . All routers exchange routing tables with each other iIn a multipoint network. C . Packets are routed based upon the shortest path to the destination. D . Paths are chosen depending on the cost efficiency factor. E . Every router in an OSPF area is capable of representing the entire network topology. F . Only the designated router in an OSPF area can represent the entire network topology.

A . An update packet with init flag set from a known， already established neighbor relationship was received by one of the routers. B . The counters were deleted. C . The ARP cache was removed. D . The IP EIGRP neighbor relationship was cleared manually.

A . Because carbon dioxide dilutes the oxygen concentration in the atmosphere and may cause asphyxiation B . Because carbon dioxide breaks down in a fire into carbon monoxide which may cause blood poisoning in the person breathing this gas C . Because carbon dioxide is a colorless and odorless gas that becomes highly toxic in the presence of high temperatures and will quickly incapacitate a person exposed to this gas D . This action is unnecessary as carbon dioxide is not poisonous nor toxic but is a relatively harmless ga

A . It supports VLSM. B . It is used to route between autonomous systems. C . It confines network instability to one area of the network. D . It increases routing overhead on the network. E . It allows extensive control of routing updates. F . It is simpler to configure than RIP v2.

A .  It supports VLSM. B .  It is used to route between autonomous systems. C .  It confines network instability to one area of the network. D .  It increases routing overhead on the network. E .  It allows extensive control of routing updates. F .  It is simpler to configure than RIP v2.

A . inetd B . route C . cfgmgr D . chdev

A . The named is not running B . The default gateway is not set C . The NIS master server is down D . Ipforwarding is not turned o

A .  route  B .  netstat  C .  iptrace  D .  traceroute&e

A . CIDR B . Split horizon C . Authentication D . Classless masking E . Hold-down timers F . Multicast routing updates G . Path Vectoring

A . To use ftp and telnet B . To perform NFS mounts C . To make /etc/hosts files unnecessary D . To reduce network traffic and save bandwidth

A . traffic separation schemes B . recommended tracks C . precautionary areas D . inshore traffic zone

A .  set bcastping to 1  B .  set ipforwarding to 1  C .  set rfc1323 to 1  D .  set directed_broadcast to 1

A．Because people were not afraid of that. B．Because tsunamis never happens in Indian Ocean. C．It would cost too much money. D．It was difficult for the people in Indian Ocean region to expect such an experience.

A、Fixed Routing B、Spanning Tree C、Source Routing D、Frame Forwarding

A．Because the examination system is not fine. B．Because it is too examination-oriented. C．Because the examination system is not scientific. D．Because the examination system is out of date.

A．distance-vector B．link-state C．flow-based D．selective flooding
