after 30 days, summarize hourly data into daily data after 60 days
D) collect response time data
every hour, summarize hourly data into daily data after 60 days

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.

B) move to static routing for all routers
C) change the routing protocol on company A's
routers to RIP
D) configure company A's routers to run RIP along
with OSPF

configuration? (Choose two)
A) NetFlow
B) SNMP
C) ICMP
D) Telnet
E) Syslog
When monitoring a remote router with a
network management system (NMS), which interface provides the most reliable
connectivity?
A) the LAN interface on the NMS
B)
the loopback interface on the NMS
C) the WAN interface on the router
D) the loopback interface on the router
Which type of Syslog message indicates
the lowest severity level?
A) debugging

Your firewall currently allows port 6343
traffic to your network management system (NMS).
What is the
port most likely being used for?

Refer to the following configuration snippet
of a Cisco IOS router:
snmp-server community private RO 60
snmp-server host 192.168.15.4 private
access-list 60 deny 192.168.12.0 255.255.240.0
access-list 60 permit snmp 192.168.15.4
The network management system (NMS) IP address
is 192.168.15.4, and it is receiving SNMP traps from the router, but it is not
able to poll the router.
Why is the NMS unable to poll the router?
A) SNMP is not enabled on the router
B) The access-list is denying SNMP access from
the NMS
C) No public community string is configured
D) The NMS requires a read-write community string
Your network management system (NMS)
leverages WMI to pull management data from Windows 2003 Servers. You have not

framework 3.5 installed
D) ensure that the account you are using exists
on all of the servers

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

What is the most likely cause of this
occurrence?
A) During network congestion, ICMP packets are
being dropped
B) Orion NPM is not configured to poll frequently
enough

packets
