39) Users at a remote site in Paris are
complaining that access to the company CRM is slow. Orion is collecting data on
this performance, but you need a more real-time perspective on the problem.
What should
you do?
A)

traffic data from these servers
42) You are monitoring your Internet connection,

B) The NAT table is overloaded
C) The WAN router is misconfigured
D) QoS is dropping low priority traffic

this error indicate?
A) The SNMP string that you used is incorrect
B) The SNMP agent on the device does not report
on this OID
C) This OID requires the read/write community
string
D) Your firewall is blocking SNMP requests

memory consumption on a server to be 95%. You connect to the server and see a
memory consumption of 80%.
What is a possible cause for this
inconsistency?
A) WMI
has been misconfigured on the server
B) The NMS is displaying an average, whereas the
server is displaying real-time data
C) The NMS is displaying real-time data, whereas
the server is displaying an average
D) The
NMS is using the wrong version of SNMP to poll the server
46) The application server team reports that the
SQL servers are NOT responding as they normally do. You check the interfaces on
the SQL servers and see that their bandwidth utilization is within normal
limits.
What is a likely cause for this SQL
application performance disruption?
A) low interface discards
B) SNMP community string change
C) access list change
D) high latency
