Question 166

Refer to the exhibit. An engineer assigns IP addressing to the current VLAN with three PCs. The configuration must also account for the expansion of 30 additional VLANS using the same Class C subnet for subnetting and host count. Which command set fulfills the request while reserving address space for the expected growth?

  1. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 265 255.255.252
  2. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255 255.255.248
  3. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255 255.255.0
  4. Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.0.1 255.255.255.128

Question 167

A client experiences slow throughput from a server that is directly connected to the core switch in a data center. A network engineer finds minimal latency on connections to the server, but data transfers are unreliable, and the output of the show interfaces counters errors command shows a high FCS-Err count on the interface that is connected to the server. What is the cause of the throughput issue?

  1. a physical cable fault
  2. a speed mismatch
  3. high bandwidth usage
  4. a cable that is too long

Question 168

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

  1. 1000BASE-LX/LH interoperates with multimode and single-mode fiber, and 1000BASE-ZX needs a conditioning patch cable with multimode.
  2. 1000BASE-ZX interoperates with dual-rate 100M/1G 10Km SFP over multimode fiber, and 1000BASE-LX/LH supports only single-rate
  3. 1000BASE-ZX is supported on links up to 1000km, and 1000BASE-LX/LH operates over links up to 70 km
  4. 1000BASE- LX/LH is supported on links up to 10km, and 1000Base-ZX operates over links up to 70 km

Question 169

What are two reasons to implement IPv4 private addressing on a network? (Choose two.)

  1. To enable internal applications to treat the private IPv4 addresses as unique
  2. To facilitate renumbering when merging networks
  3. To expand the routing table on the router
  4. To provide protection from external denial-of-service attacks
  5. To conserve global unique IPv4 addresses

Question 170

Which concern is addressed with the use of private IPv4 addressing?

  1. Lack of routing protocol support for CIDR and VLSM
  2. Lack of security protocols at the network perimeter
  3. Lack of available TCP/UDP ports per IPv5 address
  4. Lack of available publicly routable unique IPv4 address
