7- A network administrator is troubleshooting the dynamic NAT that is configured on router R2. Which command can the administrator use to see the total number of active NAT translations and the number of addresses that are allocated from the NAT pool?

10-Which WAN technology can serve as the underlying network to carry multiple types of network traffic such as IP, ATM, Ethernet, and DSL?

12-Which command can be used to check the information about congestion on a Frame Relay link?

16- What is the protocol that provides ISPs the ability to send PPP frames over DSL networks?

17- What is required for a host to use an SSL VPN to connect to a remote network device?

20 - A company connects to one ISP via multiple connections. What is the name given to this type of connection?

22-A network administrator is configuring a PPP link with the commands:
R1(config-if)# encapsulation ppp
R1(config-if)# ppp quality 70

What is the effect of these commands?

23- Which IEEE standard defines the WiMax technology?

27-What is the default location for Cisco routers and switches to send critical logging events?

28 - In the data gathering process, which type of device will listen for traffic, but only gather traffic statistics?

29-What is a characteristic of Frame Relay that allows customer data transmissions to dynamically “burst” over their CIR for short periods of time?

30-Which SNMP message type informs the network management system (NMS) immediately of certain specified events?

31 Which statement is a characteristic of SNMP MIBs?

32-What benefit does NAT64 provide?

33-What is the expected behavior of an ADSL service?

37- Which broadband technology would be best for a small office that requires fast upstream connections?

39 What is a type of VPN that is generally transparent to the end user?

44- Which circumstance would result in an enterprise deciding to implement a corporate WAN?

45-Which algorithm is considered insecure for use in IPsec encryption?

46- What is one advantage to designing networks in bulding block fashion for large companies?

48- A branch office uses a leased line to connect to the corporate network. The lead network engineer confirms connectivity between users in the branch office, but none of the users can access corporate headquarters. System logs indicate that nothing has changed in the branch office network. What should the engineer consider next to resolve this network outage?

49- Refer to the exhibit. Which IP address is configured on the physical interface of the CORP router?

50 How many 64 kb/s voice channels are combined to produce a T1 line?

51-Which network module maintains the resources that employees, partners, and customers rely on to effectively create, colaborate, and interact with information?

52 Which broadband solution is appropriate for a home user who needs a wired connection not limited by distance?

53- A network administrator is asked to design a system to allow simultaneous access to the Internet for 250 users. The ISP can only supply five public IP addresses for this network. What technology can the administrator use to accomplish this task?

54 - What is the purpose of a message hash in a VPN connection?

55- Which type of traffic would most likely have problems when passing through a NAT device?

56- Users are reporting longer delays in authentication and in accessing network resources during certain time periods of the week. What kind of information should network engineers check to find out if this situation is part of a normal network behavior?

58- What type of information is collected by Cisco NetFlow?

59- Which technology requires the use of PPPoE to provide PPP connections to customers?

63- What is used as the default event logging destination for Cisco routers and switches?

65- Which troubleshooting tool would a network administration use to check the Layer 2 header of frames that are leaving a particular host?

66-Which structured engineering desing principle ensures that the network reamins available even under abnormal conditions?

67-Two corporations have just completed a merger. The network engineer has been asked to connect the two corporate networks without the expense of leased lines. Which solution would be the most cost effective method of providing a proper and secure connection between the two corporate networks?

68- A team of engineers has identified a solution to a significant network problem. The proposed solution is likely to affect critical network infrastruture components. What should the team follow while implementing the solution to avoid interfering with other processes and infrastruture?

71-What is a Frame Relay feauture that supports the IP address-to-DLCI dynamic mapping?

72- What term is used to identify the point where the customer network ends and the service provider network begins?

73- What is used as the default event logging destination for Cisco routers and switches?

74- A small remote office needs to connect to headquarters through a secure IPsec VPN connection. The company is implementing the Cisco Easy VPN solution. Which Cisco Easy VPN component needs to be added on the Cisco router at the remote office?

75- Which scenario would require the use of static NAT?

76- An organization has purchased a Frame Relay service from a provider. The service agreement specifies that the access rate is 512 kbps, the CIR is 384 kbps, and the Bc is 32 kbps. What will happen when the customer sends a short burst of frames above 450 kbps?
