Refer to the exhibit. Why are two OSPF designated routers identified on Core_Router?
A -
Core_Router is connected to more than one multiaccess network.
B -
The router at 208.149.23.130 is a secondary DR in case the primary fails.
C -
Two router IDs have the same OSPF priority and are therefore tied for DR election
D -
The DR ecection is still underway and there are two contenders for the role.

virtual circuit. Which of the following procedures are required to accomplish this task?
A -
remove the ip address from the physical interface
B -
create the virtual interfaces with the interface command
C -
configure each subinterface with its own IP address
D -
All of the above.

Refer to the graphic. Computer 1 is consoles into switch A.Telnet connections and pings run from
the command prompt on switch A fail. Which of the following could cause this problem?
A -
switch A dose not have a cdp entry for switch B or router JAX
B -
Switch A does not have an IP address.
C -
port 1 on switch A should be an access port rather than a trunk port
D -
switch A is not directly connected to router JAX

What is one benefits of implementing vlans?
A -
A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
B -
A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
C -
Broadcast storms can be mitigated by increasing the number of broadcast domains,thus reducing their size.
D -
All of the above.

subnet mask is the most efficient for point-to-point serial links?
A -
255.255.255.240
B -
255.255.255.254
C -
255.255.255.252
D -

A switch has been configured with two vlans and is connected to a router with a trunk for inter-vlan
routing. OSPF has been configured on the router,as the routing protocol for the network. Which
statement about this network is true?
A -
For the two vlans to communicate,a network statement for the trunk interface needs to be added to the OSPF configuration.
B -
For the two vlans to communicate,a network statement for each subinterface needs to be added to the OSPF configuration.
C -
Direct inter-vlan communication does not require OSPF.
D -
OSPF cannot be used if router-on-a-stick is configured on the router.
