• Question 582:

  Which of the following commands allows a Cisco router to obtain an IP address from a DHCP server?

  A. Router(config-if)# ip address dhcp
  B. Router(config)# ip address dhcp
  C. Router(dhcp-config)# ip address dhcp
  D. Router(config)# address dhcp
  E. Router(dhcp-config)# address dhcp
  A. Router(config-if)# ip address dhcp

  ---

  The ip address dhcp command when issued from interface configuration mode will allow a router to obtain an IP address for that interface from a DHCP server.

  In this scenario, the router is acting as a DHCP client, not a server, so the command would not be issued from dhcp-config mode. In addition, the IP address is being assigned to an interface on the router, not the router as a whole so the command would not be entered at global config mode.

  The most common situation in which a router interface might be set as a DHCP client is to enable one DHCP router to obtain configuration options from another router providing this service.

  Consider an example where RouterA is connected to RouterB. RouterA contains a complete DHCP configuration including the options (DNS server, domain name). RouterB is connected to RouterA through its FastEthernet0 interface. The following configuration would allow RouterB to issue a different set of addresses than RouterA while importing the options from Router A. The configuration of RouterB is below as shown in the partial output of the show run command:

  

  Note that for this configuration to function properly, the FastEthernet0 interface on RouterB must be set as a DHCP client.

  The command router(config)# ip address dhcp is incorrect because it is executed at the global configuration prompt. The command must be executed in interface configuration mode.

  The command router(dhcp-config)# ip address dhcp is incorrect because it is executed at the DHCP configuration prompt. The command must be executed in interface configuration mode.

  The command router(config)# address dhcp is incorrect because it is missing the ip part of the command.

  The command router(dhcp-config)# address dhcp is incorrect because it is missing the ip part of the command and it is executed at the DHCP configuration prompt. It must be executed in interface configuration mode.

  Objective:

• Question 583:

  A network engineer is configuring a DHCP server to support a specialized application. Which additional DHCP feature must be enabled to support the delivery of various additional parameters to DHCP clients?

  A. modules
  B. vendor extensions
  C. options
  D. Scopes
  C. options

• Question 584:

  How does MPLS Layer 3 VPN function?

  A. When an EIGRP internal route is redistributed into BGP by one PE and then back into EIGRP by another PE, the originating router ID for the route is changed to the router ID of the first PE.
  B. When a destination PE device receives a labeled packet, it pops the label and uses it to forward the packet to the correct CE device.
  C. When a PE device forwards a packet received from a CE device across the provider network, it labels the packet with the label learned from the source PE device.
  D. When a VPN route is learned from a CE device and injected into IGP, a VPN route distinguisher attribute is associated with it.
  B. When a destination PE device receives a labeled packet, it pops the label and uses it to forward the packet to the correct CE device.

• Question 585:

  In a typical MPLS VPN, which routers act as the MPLS label imposition and disposition points in the network?

  A. CE Router
  B. P router
  C. PE Router
  D. Core router
  C. PE Router

• Question 586:

  Refer to the exhibit.

  

  A network administrator successfully logs in to a switch using SSH from a RADIUS server. When the network administrator uses a console port to access the switch, the RADIUS server returns shell:priv-lvl=15" and the switch asks to enter the enable command. When the command is entered, it gets rejected. Which command set is used to troubleshoot and resolve this issue?

  A. line con 0 aaa authorization console privl5 ! line vty 0 4 authorization exec
  B. line con 0 aaa authorization console ! line vty 0 4 authorization exec
  C. line con 0 aaa authorization console authorization priv15 ! line vty 0 4 transport input ssh
  D. line con 0 aaa authorization console authorization exec ! line vty 0 4 transport input ssh
  D. line con 0 aaa authorization console authorization exec ! line vty 0 4 transport input ssh

• Question 587:

  DRAG DROP

  Drag and drop the MPLS terms from the left onto the correct definitions on the right.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  + device that forwards traffic based on labels: P

  + path that the labeled packet takes: LSP

  + device that is unaware of MPLS labeling: CE

  + device that removes and adds the MPLS labeling: PE

• Question 588:

  A network administrator added a new spoke site with dynamic IP on the DMVPN network. Which configuration command passes traffic on the DMVPN tunnel from the spoke router?

  A. ip nhrp registration dynamic
  B. ip nhrp registration ignore
  C. ip nhrp registration no-registration
  D. ip nhrp registration no-unique
  D. ip nhrp registration no-unique

  ---

  "ip nhrp registration no-unique": allow the client to not set the unique flag in the NHRP packets. This is useful when a station has a dynamic IP address that could change over time.

• Question 589:

  Refer to the exhibit.

  

  Spoke routers do not learn about each other's routes in the DMVPN Phase2 network. Which action resolves the issue?

  A. Remove default route from spoke routers to establish a spoke-to-spoke tunnel.
  B. Configure a static route in each spoke to establish a spoke-to-spoke tunnel.
  C. Rectify incorrect wildcard mask configured on the hub router network command.
  D. Disable EIGRP split horizon on the Tunnel0 interface of the hub router.
  D. Disable EIGRP split horizon on the Tunnel0 interface of the hub router.

• Question 590:

  A switch has been configured to provide DHCP relay on VLAN 100 to a server with an IP address of 10.1.1.1. The DHCP server is sending syslog reports of multiple TFTP requests that also originate from the switch. As a result, the server CPU exceeded a configured threshold. Which action does the network administrator recommend to bring the server CPU threshold down?

  A. Configure the switch with an access list on VLAN 100 to deny TFTP.
  B. Configure the switch with a VACL on VLAN 100 to deny TFTP.
  C. Configure the switch with ip forward-protocol udp 67 globally.
  D. Configure the switch with no ip forward-protocol udp 69 on VLAN 100.
  D. Configure the switch with no ip forward-protocol udp 69 on VLAN 100.
