Your company outsources CRM to a SaaS company. Users are complaining that the CRM is

down.

You verify that Internet connectivity is good and that other Internet sites can be accessed.

You contact the CRM provider and find that none of their other customers are having issues.

You attempt to ping this IP address from your network management system (NMS), but the ping

fails. After reviewing recent changes to your outside router's configuration, you find that several

access control lists (ACLs) have been updated.

What should you do to verify that the problem is related to the ACL updates?


Options are :

  • telnet to the outside router and ping the CRM from the router's outside interface (Correct)
  • contact your ISP to see if they can access the CRM from their site
  • remove the ACLs and retest for connectivity to the CRM
  • re-ping the CRM from your NMS with a special flag so the ping will pass through the ACLs

Answer : telnet to the outside router and ping the CRM from the router's outside interface

Network usage consistently increases to near saturation levels on your Internet connection from

12:00pm to 1:00pm on most days of the week. What should you do?

  • examine NetFlow data for that time period (Correct)
  • increase Internet bandwidth from your ISP

Answer : examine NetFlow data for that time period

While monitoring your network with Orion NPM, you notice that several of the devices in your

remote offices periodically go into a "warning" state, but then quickly go back into an "up" state.

the most likely cause of this occurrence?


Options are :

  • Orion NPM is not configured to poll frequently enough.
  • Firewall rules are periodically blocking ICMP packets
  • Orion NPM is configured to poll too frequently
  • During network congestion, ICMP packets are being dropped (Correct)

Answer : During network congestion, ICMP packets are being dropped
