• Question 204:

  What is the difference between 1000BASE-LX/LH and 1000BASE-ZX interfaces?

  A. 1000BASE-ZX is supported on links up to 1000km, and 1000BASE-LX/LH operates over links up to 70 km.

  B. 1000BASE-LX/LH interoperates with multimode and single-mode fiber, and 10008ASE- ZX needs a conditioning patch cable with a multimode.

  C. 1000BASE-LX/LH is supported on links up to 10km, and 1000BASE-ZX operates over links up to 70 km

  D. 1000BASE-ZX interoperates with dual-rate 100M/1G 10Km SFP over multimode fiber, and 1000BASE-LX/LH supports only single-rate.

  Correct Answer: C

  1000BaseSX multi-mode fiber to 550 m.

• Question 207:

  When should an engineer implement a collapsed-core architecture?

  A. for small networks with minimal need for growth

  B. the access and distribution layers must be on the same device

  C. for large networks that are connected to multiple remote sites

  D. only when using VSS technology

  Correct Answer: A

  A collapsed core architecture is typically implemented in small networks, wheres as a three tier architecture is deployed into larger networks where scalabily will be a factor

  A. Enable LLDP globally.

  B. Disable CDP on gi0/0.

  C. Enable LLDP TLVs on the ISP router.

  D. Disable auto-negotiation.

  Correct Answer: A

• Question 210:

  Refer to the exhibit.

  

  The network engineer is configuring router R2 as a replacement router on the network After the initial configuration is applied it is determined that R2 failed to show R1 as a neighbor. Which configuration must be applied to R2 to complete the OSPF configuration and enable it to establish the neighbor relationship with R1?

  A. R2(config)#router ospf 1 R2(config-router)#network 192.168.1.0 255.255.255.0 area 2

  B. R2(config)#interface g0/0/0 R2(config-if)#ip ospf hello-interval 10

  C. R2(config)#interface g0/0/0 R2(config-if)#ip ospf dead-interval 40

  D. R2(config)#router ospf 1 R2(config-router)#router-id 192.168.1.2

  Correct Answer: C

  For OSPF the hello and dead timers must match to become neighbors. R1 is configured with a dead time of 40 seconds, while R2 is set to 45 seconds.
