What is a characteristic of data modeling language?

1. A. It provides an interface for state data.
2. B. It separates configuration and state data.
3. C. It ensures devices are individually configured.
4. D. It replaces SNMP.

Correct Answer: B

Simulation 3


Solution:
TASK1:Run “sh run” command on both routers, check if there is any “router ospf” configured. If it’s configured, check if Loopback0 ip it’s being used as OSPF ID. If it’s, jump to TASK2. Otherwise run:R1
router ospf 10
router-id 10.1.1.1 R2
router ospf 10
router-id 10.2.2.2 TASK2:
R1 & R2
int lo0
ip ospf 10 area 0
ip ospf network point-to-point
!
int e0/0
ip ospf network point-to-point ip ospf 10 area 0
ip ospf authentication message-digest
ip ospf message-digest-key 1 md5 C1sc0!
!

Does this meet the goal?

1. A. Yes
2. B. No

Correct Answer: A

Refer to the exhibit.

While troubleshooting a connectivity issue on router R2, a network engineer with an employee id:3876.13.497 notices that although it detects three OSPF links from R1, the OSPF prefixes are missing from the routing table. What is the reason for the problem?

1. A. The serial interfaces have different MTUs
2. B. Both loopback interfaces on R1 are configured as stub
3. C. The R2 Serial 1/0 interface is configured with an IP address, but the R1 Serial R1 Serial 1/0 interface inunnumbered.
4. D. The subnet masks on the serial interfaces are mismatched.

Correct Answer: C

Refer to the exhibit.

An engineer started to configure a router for OSPF. Which configuration must the engineer perform on the router without changing any interface configuration so that the router establishes an OSPF neighbor relationship with its peer?

1. A. router(config)# router ospf 11router(config-if)# no passive-interface ethernet 1/1
2. B. router(config)# interface ethernet 1/1router(config-if)# no shutdown
3. C. router(config)# interface ethernet 1/1router(config-if)# ip ospf hello-interval
4. D. router(config)# interface ethernet 1/1router(config-if)# ip ospf priority 0

Correct Answer: A

Refer to the exhibit:

A network engineer is implementing an OSPF configuration Based on the output, which statement is true?

1. A. In the ospfv3 1 area 1 ipv4 command, area 0 must be configured instead of area 1.
2. B. OSPFv3 does not run for IPv4 on FastEthemet0/0 until IPv6 routing is enabled on the router and IPv6 isenabled on interface Fastfc.thernet0/0
3. C. OSPFv3 cannot be configured for IPv4; OSPFv3 works only for IPv6.
4. D. IPv6 routing not enabled" is just an informational message and OSPFv3 runs for IPv4 on interface FastEthernet0/0 anyway

Correct Answer: B
