  • C: Issue the ping {default gateway IP address} command from the Windows command line on your laptop to verify connectivity to the default gateway.
  • D: Issue the ping {DNS server IP address} command from the Windows command line on your laptop to verify connectivity to the DNS server.
  • E: Issue the ping tcp www.cisco.com 80 command from the Windows command line on your laptop to verify TCP port 80 connectivity to the www.cisco.com server.
  • F: From the ISR G2 CLI, issue the ping tcp www.cisco.com 80 command to verify TCP port 80 connectivity to the www.cisco.com server.

Question 5
Refer to the exhibit. The netstat command is used to troubleshoot network issues at which OSI layer?  

  

  • A: application
  • B: network
  • C: data link
  • D: transport

  • A: SNMP

Question 7
You are assessing a network design proposal for a new site which includes the following requirements: 
There are 252 users in three floors  
Each floor has an access wiring cabinet serving the connections on that floor  
The MDF is located in the basement and is connected to the IDFs via a resilient MM fiber  
A 1Gbps dedicated Internet connection terminates in the MDF 
The proposal specifies 2 Cisco Catalyst 2960X-48TD-L for each IDF and a single 2960X-48TS-L for the MDF to terminate the access connections and a Cisco Meraki MX400 Security Appliance. Which feedback should you give?

  • A: The design is not valid because all Greenfield locations must be wireless first and so the design must be completely redone
  • B: The design is not valid because the cabling must be cat6a to achieve 802.3ab speeds
  • C: The design is not valid because the core 2960X-48TS-L has only four SFP ports, which means that the resilient fiber runs are wasted
  • D: The design is valid but the Cisco Meraki MX400 must be replaces with a Cisco ASA firewall because you see no value in cloud-based networking



Question 8
Refer to the exhibit. 

  

Which layer(s) of the TCP/IP model operates end-to-end (Host A to Host B)?

  • A: Physical layer
  • B: Link layer
