An ISP has an IP/MPLS core network. Recently, after replacing low-capacity routers with two
Cisco Carrier Routing System routers, customer has complained about reduced application
performance (slow website access). What is the most likely cause for this issue?

There is a defective egress queuing ASIC in the data path of a router. Under certain conditions,
the ASIC may flip a bit from a large data packet from 0 to 1. The bit flip can occur only on a bit
position greater than 128 bytes. What is the accurate statement about FTP flow transiting through
this ASIC over a PPP SONET port?

Assume that you have to manage a network with several remote locations. You are told that you
need to collect performance data from each remote location to access the total traffic that goes to
the corporate office, that go to other remote locations, and that go outside of the organization.
Your low-bandwidth WAN connection that goes to the NOC does not have enough bandwidth to
allow for export of all of the data from the remote locations. What other option should you pursue?

Refer to the syslog message generated by a Cisco IOS device: *Mar 6 22:48:34.452 UTC.
%LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up. What
does the special character (*) indicate?

Why are thresholds defined based on baseline documents?

What is the main difference between an SNMP trap and a syslog message?

Why do event management systems use device-generated events (that is, TRAP, syslog) instead
of poll-based?

Performance and accounting management are similar because both are interested in collecting
usage data from the network. How do they differ?

A new polling application was installed last week. This application monitors some of the routing
characteristics on your edge and aggregation devices. Since that time, you have been receiving
CPU threshold utlization alerts between 1 and 4 a.m. every day from multiple edge and
aggregation devices. What is the most likely cause of CPU spikes, in light of the specified changes
and assuming that no other changes happened in the network?

An ISP operates a network that provides VPN service to enterprise customers. The customer uses
an MPLS network that is designed with redundant equal cost paths in the core. An enterprise
customer reported an increased latency and drop rate for some traffic flows from site A to site B.
The enterprise customer is connected to PE-A at site A and PE-B at site B.
If the latency problem is caused by a congested link in the core along a path from site A to site B,
which of the following statements is correct?
