  A. RIB
  B. FEC
  C. LDP

• Question 743:

  An engineer is troubleshooting on the console session of a router and turns on multiple debug commands. The console screen is filled with scrolling debug messages that none of the commands can be verified if entered correctly or display any output.

  Which action allows the engineer to see entered console commands while still continuing the analysis of the debug messages?

  A. Configure the term no mon command globally.
  B. Configure the logging synchronous level all command.
  C. Configure the logging synchronous command.
  D. Configure the no logging console debugging command globally.
  C. Configure the logging synchronous command.

  ---

  Let's see how the "logging synchronous" command affect the typing command:

  Without this command, a message may pop up and you may not know what you typed if that message is too long. When trying to erase (backspace) your command, you realize you are erasing the message instead.

  

  With this command enabled, when a message pops up you will be put to a new line with your typing command which is very

  

• Question 744:

  Which protocol is used in a DMVPN network to map physical IP addresses to logical IP addresses?

  A. BGP
  B. LLDP
  C. EIGRP
  D. NHRP
  D. NHRP

• Question 745:

  You are troubleshooting an issue with the configuration of mGRE on the hub router in a hub-and-spoke configuration. Examine the output of the configuration of the tunnel interface on the hub router:

  

  Which of the following statements is true?

  A. The tunnel destination must be specified on the tunnel interface
  B. the tunnel mode gre multipoint command must be executed on the tunnel interface
  C. the tunnel mode gre multipoint command must be executed on the physical interface
  D. The tunnel destination must be specified on the physical interface
  B. the tunnel mode gre multipoint command must be executed on the tunnel interface

  ---

  The tunnel mode gre multipoint command must be executed on the tunnel interface. An mGRE configuration is one in which the tunnel is allowed to have multiple destinations. The distinguishing feature between an mGRE interface and a point-to-point GRE interface is the tunnel destination. While it is specified on a point-to-point GRE interface, it is not on an mGRE interface. Instead the command tunnel mode gre multipoint is executed on the tunnel interface. This allows the interface to use the Next Hop

  Routing protocol (NHRP) to discover the IP addresses of the other tunnel endpoints.

  The tunnel destination is not specified on the tunnel interface using mGRE. Instead the command tunnel mode gre multipoint is executed on the tunnel interface.

  The tunnel mode gre multipoint command must be executed on the tunnel interface, not the physical interface. The tunnel destination is neither specified on the tunnel interface nor on the physical interface when using mGRE.

  Objective:

  VPN Technologies

  Sub-Objective:

  Configure and verify GRE

• Question 746:

  What is the function of BFD?

  A. It provides uniform failure detection regardless of media type.
  B. It creates high CPU utilization on hardware deployments.
  C. It negotiates to the highest version if the neighbor version differs.
  D. It provides uniform failure detection on the same media type.
  A. It provides uniform failure detection regardless of media type.

• Question 747:

  The network administrator is tasked to configure R1 to authenticate telnet connections based on Cisco ISE using RADIUS. ISE has been configured with an IP address of 192.168.1.5 and with a network device pointing towards R1 (192.168.1.1) with a shared secret password of Cisco123. If ISE is down, the administrator should be able to connect using the local database with a username and password combination of admin/cisco123.

  The administrator has configured the following on R1:

  aaa new-model ! username admin password cisco123 ! radius server ISE1 address ipv4 192.168.1.5 key Cisco123 ! aaa group server tacacs+ RAD-SERV server name ISE1 ! aaa authentication login RAD-LOCAL group RAD-SERV

  ISE has gone down. The Network Administrator is not able to Telnet to R1 when ISE went down.

  Which two configuration changes will fix the issue? (Choose two.)

  A. aaa authentication login RAD-SERV group RAD-LOCAL local
  B. aaa authentication login RAD-LOCAL group RAD-SERV local
  C. line vty 0 4 login authentication RAD-LOCAL
  D. line vty 0 4 login authentication default
  E. line vty 0 4 login authentication RAD-SERV
  B. aaa authentication login RAD-LOCAL group RAD-SERV local
  C. line vty 0 4 login authentication RAD-LOCAL

• Question 748:

  Refer to the exhibit.

  

  A network engineer finds that PC1 is accessing the hotel website to do the booking but fails to make payment. Which action resolves the issue?

  A. Increase the AD to 200 of static route 192.168.94.0 on R3.
  B. Configure a reverse route on R1 for PC1 172.16.1.0/24.
  C. Decrease the AD to 5 of OSPF route 192.168.94.0 on R1.
  D. Allow stub network 10.10.202.168/30 on router R3 OSPF.
  B. Configure a reverse route on R1 for PC1 172.16.1.0/24.

• Question 749:

  Refer to the following partial output of the show ip bgp neighbors command:

  

  Which of the following can NOT be determined from the given output? (Choose all that apply.)

  A. The ASN of rtrA
  B. The ASN of 172.161.81.7
  C. The best paths between rtrA and the 172.161.81.7 neighbor
  D. The RID of the 172.161.81.7 neighbor
  E. The status of the connection between rtrA and 172.161.81.7
  A. The ASN of rtrA
  C. The best paths between rtrA and the 172.161.81.7 neighbor

  ---

  The autonomous system number (ASN) of rtrA and the best paths between rtrA and the 172.161.81.7 neighbor cannot be determined from the given output.

  The show ip bgp neighbors command displays the TCP and BGP connections from a given router to its neighbors. This command is executed in EXEC mode. You can use various optional keywords to view different aspects of the neighbors. For example, this command can display the details about a given neighbor, routes advertised to or received from neighbors, and the prefix-list received by neighbors.

  In this case, the command is used to show the details about a specific neighbor of rtrA. The IP address (172.161.81.7) of the neighbor is provided in the command. The text BGP neighbor is 172.161.81.7 indicates the IP address of the neighbor. The text remote AS 151 indicates that the neighbor is in the ASN 151. It can also be determined from the text external link that the neighbor is an eBGP neighbor. For iBGP neighbors, the text internal link will appear. The router ID (RID) of the neighbor can be

  determined from the text remote router ID 10.8.22.4.

  The output also provides details about the state of the BGP connection, which is Established in this case. Furthermore, the duration for which the connection has been established, the duration for which BGP maintains neighbor relationship in the absence of messages, and the keepalive duration are also displayed.

  The state of the connection between the local router (rtrA) and the given neighbor (172.161.81.7) can be any of the following:

  Idle Indicates that the local router does not accept any connection from its neighbor Idle (admin) Indicates that the connection between the two routers has been shut down administratively by using the neighbor shutdown command Connect Indicates that the local router has already sent an connection request to its neighbor Active Indicates that the local router is listening for connection requests from the neighbor OpenSent Indicates that the local router has sent an OPEN message to its neighbor

  OpenConfirm Indicates that the local router has received a KEEPALIVE or UPDATE message from its neighbor Established Indicates that a BGP connection has been successfully created between the local router and its neighbor

  The status of the connection between two BGP neighbors can also be viewed by using the show ip bgp summary command, as shown below:

  

  In the above output, it can be determined that the command router bgp 210 was executed on rtrA because the local AS is 210 in the output. It can be determined that the command neighbor 45.1.1.5 shutdown was issued on rtrA because the state of the neighbor relationship with the router at 45.1.1.5 is listed as IDLE(ADMIN).

  All the other options are incorrect because the respective details are displayed by the show ip bgp neighbors command.

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify eBGP (IPv4 and IPv6 address families)
