In the ECNM, where should an IPS or IDS be configured.
- A.
Enterprise Edge
- B.
Enterprise Campuse
- C.
Service Provider Edge
- D.
WAN Edge
Correct Answer
A. Enterprise EdgeExplanation
An IPS or IDS should be configured in the Enterprise Edge.

Which tool would enable a teleworker to communicate in real time with colleague?
- A.
FTP
- B.
E-mail
- C.
Chat
- D.
Telnet
Correct Answer
C. ChatExplanation
The tool that would enable a teleworker to communicate in real time with a colleague is chat. Chat allows for instant messaging and real-time communication, allowing teleworkers to have quick and efficient conversations with their colleagues regardless of their physical location. FTP is a file transfer protocol, not a communication tool. Email allows for asynchronous communication and is not real-time. Telnet is a remote login protocol and does not provide real-time communication capabilities.Rate this question:

What type of traffic, if found on an enterprise WAN link, indicates a problem with the network design?
- A.
Departmental File Sharing
- B.
Printing
- C.
Internal Backup
- D.
Intracampus voice
- E.
All the above
Correct Answer
E. All the aboveExplanation
If all of the listed types of traffic (departmental file sharing, printing, internal backup, and intracampus voice) are found on an enterprise WAN link, it indicates a problem with the network design. This is because these types of traffic should ideally be handled within the local network or through more efficient means such as dedicated servers or local backups. Having them traverse the WAN link can lead to increased network congestion, reduced performance, and unnecessary strain on the network infrastructure.Rate this question:

One evening a network administrator attempted to access a recently deployed website and received a “page not found” error. The next day the administrator checked the web server logs and noticed that during the same hour that the site failed to load, there was hundreds of requests for the website home page. All of the requests originated from the same IP address. Given this information, what might the network administrator conclude?
- A.
It is normal web surfing activity.
- B.
It is likely that someone attempted a DoS attack.
- C.
The link to the website does not have enough capacity and needs to be increased.
- D.
The web server was turned off and not able to service requests.
Correct Answer
B. It is likely that someone attempted a DoS attack.Explanation
Based on the information provided, the network administrator can conclude that someone likely attempted a DoS (Denial of Service) attack on the website. The fact that there were hundreds of requests for the website home page originating from the same IP address during the hour when the site failed to load suggests a deliberate attempt to overload the server and disrupt its functionality. This pattern of activity is indicative of a DoS attack rather than normal web surfing activity or server capacity issues. The possibility of the web server being turned off is not supported by the given information.Rate this question:

Which of the following protocols can be used to access a Cisco router for in-band management?
- A.
ARP
- B.
SSH
- C.
FTP
- D.
SMTP
- E.
Telnet
- F.

What attribute is associated with link-state routing protocols?
- A.
Hop Count
- B.
Poison reverse
- C.
Low processor overhead
- D.
Shortest path first calculation
Correct Answer
D. Shortest path first calculationExplanation
Link-state routing protocols, such as OSPF and IS-IS, use the concept of shortest path first calculation. This means that each router in the network calculates the shortest path to every other router based on the information it has about the network topology. This information is then shared with other routers in the network, allowing them to build a complete map of the network and determine the best path for forwarding packets. This approach ensures efficient and optimal routing decisions, as it takes into account factors like link costs and network congestion.Rate this question:
