1,What type of interface will be created when the command ppp multilink is added to an ISDN BRI interface?
E. virtual-access 1
Explanation:
MPPP is a method for splitting, recombing, and sequencing datagrams across multiple logical data links. It was originally motivated
by the desire to exploit multiple bearer channels in ISDN, but it is equally applicable to any situation in which multiple ppp
links connect two systems, including async links
Traffic routed across an MPPP link via its controlling interface will be fragmented, with the fragments being sent across the
different physical links. At the remote end of the link, the fragments are reassembled and forwarded to the next hop toward their ultimate destination.
After MPPP has been successfully negotiated during the LCP phase of PPP negotiation and Challenge Handshake Authentication
Protocol(CHAP) or Password Authentication Protocol(PAP) have completed successfully, a Virtual Access interface will be created by the Cisco IOS Software to represent the MPPP bundle
2,You're in the midst of troubleshooting a remote network connection to your ISP from router TK1. What could you eliminate as a problem source before you even contact the ISP?
B. Segment between the local router and the CSU
D. Segment between the local CSU and the service provider's switch
Explanation:
Before contacting the ISP for fault isolation, first we should successfully complete the loopback testing on your local and remote
segments. The service provider can not help fixing the local segments between your routers and the local CSU. In this case, we
really only have visibility on the local side. We can test connectivity between the local router and CSU using a loopback test. If that succeeds, we can then try to test the connection between the local CSU and the ISP. If that fails, then we can contact the service provider
3,During your lunch break your junior administrator made a mistake on the network and is on the phone with a TAC engineer trying to
work it out. You overhear the phone conversation and notice that the engineer assigned to his ticket asks for the "show
interface"and "show protocol"output. Which two situations is the engineer probably investigating?
C. Partial loss of system function
D. Lost data or performance problems
4,Cisco Technical Assistance Center(TAC) has priority levels.
Priority 1:Production network is down, causing critical impact to business operations if service is not restored quickly
Priority 2:Production network is severely degraded, impacting significant aspects of your business operations
Priority 3:Network performance is degraded.Network functionality is noticeably imparired,but more business operations continue
Priority 4:Customer requires information or assistance on Cisco product capabilities, installation, or configuration
5,Network modeling:NetSys
Inventory and software distribution:CRM
Network utilization:TrafficDirector
Graphically configure a device:CiscoView
Netsys is an offline tool. It is a complex program that imports Cisco device configuration and then creates a model based on the
configurations. The program is used to model changes to a network before they are actually implemented
Cisco Resource Mananger(CRM) is web-based and among its components there are four essential applications:Inventory
manager,availability manager, syslog analyzer,and software image manager
TrafficDirector obtains traffic information from embedded RMON agents. With this information about different
segments,TrafficDirector can inform you of collision, error,utilization,and broadcast rates.
CiscoView provides real-time device level monitoring,fault management,and troubleshooting,with a Graphic user interface
6,You've arrived at the job site and you're greeted by your junior administrator who tells you that she's just diagnosed a flapping
link on the Frame Relay network,and asks you what two problems could lead to a flapping link?
A. too much line noise
B. improperly configured keepalives
7,In Frame Relay, what DLCI number is associated with the ANSI LMI type?
A. 0
Explanation:
The three LMI types and their respective DLCI number's are:
a. Cisco-1023
b. Ansi-0
c. Q933a-0
8,You have a 512 kbps Frame Relay network, and you are experiencing some network latency with some real-time data because of the time it's taking to serialize packets. What could you do to reduce the delay on this network?
A. Link fragmentation and interleaving
C. Low latency queuing
9,Your junior administrator is troubleshooting a Windows based end system. You notice that she's just entered the command nslookup. At what OSI layer does she suspect the problem to be at?
E. application
This command displays the DNS name/IP host information, indicating that a problem exists while trying to connect to a web site via HTTP or an email server. Either way, the problem appears with an application not working properly
10,When troubleshooting a Windows end-system, which command gathers data by identifying the path that a packet takes through the network?
B. tracert
Explanation:
Tracert for Microsoft and tracerout for Cisco will help the network administrator to carry out troubleshooting by gathering the symptoms and identifying the path a packet takes through the network. This utility will show the router hops that the path takes, as well as the latency between each hop
