A. high CPU values on WAN routers B. WAN bandwidth availability C. SQL database scalability issues D. redundancy for single-homed sites Answer: B A firewall separates Orion NPM and the network devices it is monitoring. Only encrypted communication will be allowed from the server for polling and configuration management. Which two ports will need to be allowed through the firewall? (Choose two.) A.22 B.23 C.69 D.80 E.161 F.2055 Answer: A,E Companies A and B have merged and are both using the 10.10.x..x /16 networks. Company A uses Orion NPM and would like to monitor two key servers within company B's network. Which solution for this situation involves the fewest configuration steps? A. use static NAT B. use dynamic NAT C. re-address company B's network D. use DNS for accessing the servers Answer: A Company A and company B have merged and are currently planning to combine their network backbones. All 18 of company A's routers run OSPF, but company B's hardware only supports RIPv2. You need to monitor both networks from a single NMS.
Which
solution involves the fewest configuration steps to meet these monitoring
requirements?
A. move to static routing for all routers B. change the routing protocol on company A's routers to RIP C. use router redistribution D. configure company A's routers to run RIP along with OSPF Answer: C How should you visually represent service level agreement (SLA) interface utilization thresholds within the Orion NPM Web Console?

From
your core site, your network management system (NMS) has detected that both
the WAN router and the switch in one of your remote sites are unreachable.
What should be your first step in identifying the root cause? A. examine the state of the adjacent core router's interface B. examine the switch configuration at the core site C. examine the router configuration at the remote site D. examine the state of the remote router's WAN interface Answer: A 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? A .increase Internet bandwidth from your ISP B. check the ping times to your core router C. examine Net Flow data for that time period D. turn off Internet access and see who complains Answer: C 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. While the devices are in "warning" state, the users at those sites report normal operations. What is the most likely cause of this occurrence? A. Orion NPM is configured to poll too frequently. B. During network congestion, ICMP packets are being dropped. C. Orion NPM is not configured to poll frequently enough. D. Firewall rules are periodically blocking ICMP packets. Answer: B You are using NetFlow to analyze the traffic on your network. You notice that you have a large amount of traffic originating from various systems in your network destined to a single unrecognized off-net IP address during otherwise off-peak hours. What is the most likely cause? A. a new, popular YouTube video being sent around the office B. a malware or virus breakout on your network C. automated server backups occurring within your network D. higher than average VoIP usage from your overseas sites Answer: B What is a potential root cause of a slow response time across a WAN circuit? A. interface re-indexing on a WAN router B. high disk queue length on the SQL server C. database replication across the circuit D. large database re-indexing Answer: C You are investigating sudden slowness throughout the network. The routing tables are changing continuously and routes to many areas of the network are appearing and disappearing with each update. How should you investigate the cause of this issue? A. examine the available memory B. analyze routing protocol packets C. look for switch ports that are off D. look for WAN interfaces changing status Answer: D What is the most direct way to measure an application's performance? A. ping the application server B. collect application data in NetFlow C. time application transactions D. collect application server CPU and memory statistics Answer: C When monitoring the performance of the WAN connection to a remote site, you notice that latency varies from 10 to 1700 milliseconds and that bandwidth utilization is commonly over 90%. Which type of traffic would be the most adversely affected by this situation? A. email B.SNMP polling C. VoIP D. Syslog Answer: C To add previously unmonitored humidity statistics to a report, which two components should you use? (Choose two.) A. Universal Device Poller (UnDP) B.MIB Walker C. System Manager D. Report Writer E. Report Scheduler F. Web Console Answer: A,D You need to write a report that shows network response time on an hourly basis for the past 30 days. When you try to set the summarization setting in the report to hourly, you get a reporting error. What is a possible cause of this issue? A. Hourly data are being summarized into weekly data every 15 days. B. Response time data are only being collected every 30 minutes. C. Response time data are only being collected every60 minutes. D. Hourly data are being summarized into weekly data every 40 days. Answer: A A network engineer has created a custom report in Orion NPM with the following parameters: 1. Fields are set to "Node ID, Node Name, Average Response Time." 2. Time frame is set to "Last30 days." 3. Summarization is set to "Month." What is an accurate representation of what this report will display? A. average response time for the last month on all devices and interfaces B. average response time for the last month on all devices C. average response time per day of the last month on all devices and interfaces D. average response time per day of the last month on all devices Answer: B

Every Monday morning, you need to provide a report on the previous weeks
network-wide availability. Which component should you use to accomplish this
task?
A. Orion Report Writer B. Orion Report Scheduler C. Windows Task Scheduler D. Orion Web Console Scheduler Answer: B Your auditors require you to run monthly network performance reports and to save that data for three years. Using Orion NPM, how should you meet this requirement while optimizing the system around performance and database size? A. build monthly reports, run them every month, save the output for three years B. build monthly reports, run them monthly, retain the data in the database for three years C. build annual reports that break the data out by month, run the reports annually, save the output forthree years D. build monthly reports, run them anytime the auditors request, retain the data in the database for three years Answer: A |
