Question 1

One of your network administrators has deployed a new access control list (ACL) that blocks UDP port 69. As a result of this change, what might the network management system (NMS) NO longer be able to do?

Accepted Answer

UDP port 69 is used by the Trivial File Transfer Protocol (TFTP), which is commonly used for transferring files such as IOS updates to network devices. Blocking this port would prevent the NMS from updating IOS on devices.

Question 2

Which Orion NPM module allows you to create user-experience monitors?

Accepted Answer

The Application Performance Monitor (APM) module in Orion allows you to create user-experience monitors by tracking the performance and availability of applications.

Question 3

While isolating a bandwidth issue using your network management system (NMS), you discover that the percent utilization for an interface is over 100%. What is a possible cause?

Accepted Answer

The NMS may be configured with the wrong interface speed, leading to incorrect calculations of percent utilization, potentially showing values over 100%.

Question 4

You believe that a QoS misconfiguration may be causing poor performance on your network. What should you check to verify that QoS is the root cause?

Accepted Answer

Checking bandwidth and packet drops can help determine if QoS settings are causing congestion or prioritization issues, leading to poor network performance.

Question 5

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?

Accepted Answer

VoIP (Voice over IP) is highly sensitive to latency and jitter, which can cause poor call quality, delays, and dropped calls. High bandwidth utilization and variable latency would significantly impact VoIP traffic.

Question 6

Orion is displaying a device as "down" and is unable to communicate with the device via ICMP. However, you are able to ping that device from the command-line on the Orion server. Orion is displaying other devices as being "up". What is a possible cause of this issue?

Accepted Answer

ICMP messages with content in the payload portion of the packets might be blocked by a firewall or security device, causing Orion to show the device as "down" even though it can be pinged from the command line.

Question 7

An Orion NPM user wants to be able to make changes to the resources as they view them on the Orion Web Console. What must be done to the user's account?

Accepted Answer

The answer of An Orion NPM user wants to be...

Question 8

Lower than normal throughput is being experienced between two routers. What can be seen on the router interface that may be contributing to this issue?

Accepted Answer

The answer of Lower than normal throughput is being experienced...

Question 9

A device is NOT responding to pings. What can you determine from this information?

Accepted Answer

The device may be down, but it could also be due to other reasons like network issues or firewall settings blocking pings.

Question 10

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?

Accepted Answer

The answer of You are investigating sudden slowness throughout the...

Question 11

As your Orion NPM deployment grows, you need to add pollers to the system, but due to budgetary constraints, you are unable to do so. What should you do in the short term to allow you to add a few more elements?

Accepted Answer

Adjusting polling intervals can help manage the load on existing pollers by reducing the frequency of data collection, allowing you to add more elements without immediately needing additional pollers.

Question 12

The application team at your company has informed you that they have deployed a new desktop application that communicates over a specific set of ports. What is the first step to determining the impact this application is having on your network?

Accepted Answer

Configuring the NetFlow collector to monitor the application ports will allow you to analyze the traffic patterns and determine the impact the new application is having on the network.

Question 13

You have a hub and spoke network with three sites. The application servers all located within the headquarters, which is the hub of the network. Users in spoke site A complain that they cannot get to the company's accounting server. Users in spoke site Bare not affected. Which two steps should you take in troubleshooting this issue? (Choose two.)

Accepted Answer

The answer of You have a hub and spoke network...

Question 14

While growing the network monitoring team, what is the most appropriate way to ensure that the Orion NPM is not over-utilized?

Accepted Answer

The answer of While growing the network monitoring team, what...

Question 15

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?

Accepted Answer

A large amount of traffic to a single unrecognized off-net IP address during off-peak hours is suspicious and could indicate a malware or virus breakout, as it may be attempting to communicate with a command and control server.

Question 16

What is different about how network traffic statistics are collected using SNMP versus NetFlow?

Accepted Answer

NetFlow is push-based, meaning it actively sends flow records to a collector, whereas SNMP is typically pull-based, where a management system queries devices for statistics.

Question 17

When planning the deployment of the database server for Orion NPM, what are two primary considerations? (Choose two.)

Accepted Answer

RAID configurations are important for data redundancy and performance, while CPU and memory size are crucial for handling the load and ensuring smooth operation of the database server.

Question 18

An executive in your company wants to see reports from the Orion website. However, Sarbanes-Oxley (SOX) rules preclude you from giving them an account for the website. Which type of access should you use to allow them to see reports that are sent to them?

Accepted Answer

DirectLink allows users to view reports without needing an account, complying with SOX rules.

Question 19

Which two types of data does Orion NetFlow Traffic Analyzer collect from network devices? (Choose two.)

Accepted Answer

Orion NetFlow Traffic Analyzer collects data using NetFlow and sFlow protocols, which are used for monitoring network traffic.

Question 20

Your company leverages Internet-based VPNs to provide connectivity to remote offices. At these sites, the users are connected directly to a layer 2 switch, which is then connected to a VPN concentrator that also provides basic routing functions. How should you analyze the traffic going to and from a remote site?

Accepted Answer

The answer of Your company leverages Internet-based VPNs to provide...
