How do EIGRP routers establish and maintain neighbor relationships?
by exchanging neighbor tables with directly attached routers
by comparing known routes to information received in updates
by exchanging hello packets with neighboring routers
by dynamically learning new routes from neighbors
by exchanging routing tables with directly attached routers
The IPv6 autoconfiguration feature enables a PC to automatically connect to an IPv6 network. What type of IPv6 address allows a PC host to send a router solicitation message requesting a prefix for stateless autoconfiguration?
link local address
site local address
aggregatable global unicast address
loopback address
IPv4-compatible address
flow-label address
During an interview, the company IT manager mentions that the company has two critical communication links to its main supplier. These links require an uptime of 24/7. Which part of the PPDIOO process is most affected by this information?
design phase
implementation phase
routing protocol selection
prototype design plan
Refer to the exhibit. The RIP routes must be injected into the OSPF domain. Which command will perform external route summarization?
RTB(config-router)# summary-address 192.168.16.0 255.255.252.0
RTA(config-router)# summary-address 172.20.0.0 255.255.0.0
RTB(config-router)# area 1 range 192.168.16.0 255.255.252.0
RTA(config-router)# area 1 range 172.20.0.0 255.255.0.0
Refer to the exhibit. access-list 111 permit ip 10.0.0.0 0.255.255.255 any route-map net-10 permit 10 match ip address 111 set interface FastEthernet 0/1 Where would the system administrator apply the above configuration to establish policy-based routing that directs packets from the 10.0.0.0/8 network through the R2 router to the Internet?
RTA interface Fa 0/0
RTA interface Fa 0/1
RTB interface Fa 0/1
RTB interface Fa 1/0
R2 interface Fa 0/0
R2 interface Fa 0/1
How does OSPF exchange routing updates when the passive-interface command is applied?
OSPF forms neighbor adjacencies on that interface.
The OSPF interface enters an active state.
OSPF stops sending routing updates out that interface.
OSPF only receives routing updates on that interface.
OSPF neither sends nor receives routing updates through that interface.
Which functional component of the Cisco Enterprise Architecture is responsible for hosting internal servers?
enterprise edge
enterprise campus
service provider edge
building distribution
Refer to the exhibit. A network administrator has configured EIGRP authentication between routers R1 and R2. After the routing tables are reviewed, it is noted that neither router is receiving EIGRP updates. What is a possible cause for this failure?
The same number of key strings must be used on each router.
The same key chain name must be used on each router.
The same autonomous system numbers must be used in the interface configurations of each router.
The authentication configuration is correct, but the show ip eigrp neighbors command should be issued to troubleshoot the issue.
