Which of the following describe the process identifier that is used to run OSPF on a router?
A -
It is locally significant.
B -
It is globally significant.
C -
It is an optional parameter required only if multiple OSPF processes are running on the router.

R1(config)# interface ethernet 0 R1(config-if)# ip address 192.1.1.129 255.255.255.192 R1(config-if)# no shutdown
B -
R1(config)# interface serial 0 R1(config-if)# ip address 192.1.1.6 255.255.255.252 R1(config-if)# no shutdown
C -
R1(config)# router rip R1(config-router)# version 2 R1(config-router)# network 192.1.1.0
D -
All of the above

A network administrator wants to ensure that only the server can connect to port Fa0/1 on a
Catalyst switch. The server is plugged into the switch Fa0/1 port and the network administrator is
about to bring the server online. What can the administrator do to ensure that only the MAC
address of the server is allowed by switch port Fa0/1?
A -
Configure port Fa0/1 to accept connections only from the static IP address of the server.
B -
Employ a proprietary connector type on Fa0/1 that is incompatible with other host connectors.
C -
Configure the MAC address of the server as a static entry associated with port Fa0/1.
D -
Bind the IP address of the server to its MAC address on the switch to prevent other hosts from spoofing the server IP address.

The internetwork infrastructure of company XYZ consists of a single OSPF area as shown in the
graphic. There is concern that a lack of router resources is impeding internetwork performance. As
part of examining the router resources, the OSPF DRs need to be known. All the router OSPF
priorities are at the default and the router IDs are shown with each router. Which routers are likely
to have been elected as DR?
A -
Corp-1
B -
Corp-2
C -
Corp-3
D -
Corp-4
8-
At which layers of the OSI model do WANs operate?
A -
datalink layer
B -
network layer
C -
transport layer
D -
session layer
9-
Which routing protocols can be used within the enterprise network shown in the diagram?
A -
RIPv2
B -
OSPF
C -
EIGRP
D -
All of the above
10-
Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are
possible reasons for this problem?
A -
All of the routers need to be configured for backbone Area 1.
B -
R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.
C -
A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.
D -
The hello and dead interval timers are not set to the same values on R1 and R3.
