Cisco 300-410 Online Questions & Answers

• Question 381:

  A TFTP server, a DNS server, and a TACACS server are residing in the 192.168.5.0/24 subnet. Their IP addresses are 192.168.5.2, 192.168.5.3, and 192.168.5.4, respectively.

  You would like to configure the routers to forward UDP broadcasts to these servers.

  Which of the following commands or sets of commands would configure this to occur using the LEAST number of commands?

  A. ip helper-address 192.168.5.2 69 ip helper-address 192.168.5.3 53 ip helper-address 192.168.5.4 49
  B. ip helper-address 192.168.5.2 ip helper-address 192.168.5.3 ip helper-address 192.168.5.4
  C. ip helper-address 192.168.50 69 53 49
  D. ip helper-address 192.168.5.255
  D. ip helper-address 192.168.5.255

  ---

  The only command required is ip helper-address 192.168.5.255. This command is a directed broadcast to the subnet on which the servers reside which will cause all servers to receive the broadcast. Each server will process only the packets aimed at the port on which they are listening.

  It not necessary to specify any port numbers because the ip helper-address command will forward to the following ports by default:

  NTP - port 37

  TACACs - port 49

  DNS - port 53

  BootP - port 67

  TFTP - port 69

  NetBIOS Name server - port 137

  NetBIOS Datagram server - port 138

  While the following command set would work, it does not contain the least number of commands:

  ip helper-address 192.168.5.2 69

  ip helper-address 192.168.5.3 53

  ip helper-address 192.168.5.4 49

  It is not required to specify each server and its respective port number.

  The following command set would also have the desired results, because port numbers are not required for the default services:

  ip helper-address 192.168.5.2

  ip helper-address 192.168.5.3

  ip helper-address 192.168.5.4

  However, this is not the least number of commands you can execute to achieve the solution.

  The command ip helper-address 192.168.50 69 53 49 would not work because it is addressed to the network number of the subnet to which the servers are connected. To send to them all requires a directed broadcast.

  Objective:

  Infrastructure Services

  Sub-Objective:

  Configure and verify IPv4 and IPv6 DHCP

• Question 382:

  Refer to the exhibit.

  

  BGP is flapping after the CoPP policy is applied.

  What are the two solutions to fix the issue? (Choose two.)

  A. Configure a three-color policer instead of two-color policer under Class COPP-CRITICAL-7600.
  B. Configure IP CEF for CoPP policy and BGP to work
  C. Configure a higher value for CIR under the default class to allow more packets during peak traffic
  D. Configure a higher value for CIR under the Class COPP-CRITICAL-7600.
  E. Configure BGP in the COPP-CRITICAL-7600 ACL.
  C. Configure a higher value for CIR under the default class to allow more packets during peak traffic
  E. Configure BGP in the COPP-CRITICAL-7600 ACL.

  ---

  The policy-map COPP-7600 only rate-limit HTTP and HTTPS traffic (based on the ACL conditions) so any BGP packets will be processed in the class "class-default", which drops exceeded BGP packets. Therefore we have two ways to solve this problem:

  +

  Add BGP to the ACL with the statement "permit tcp any any eq bgp"

  +

  Configure higher value for CIR in default class as 2Mbps is too low for web traffic (http and https)

• Question 383:

  A company Is redesigning WAN infrastructure so that all branch sites must communicate via the head office and the head office can directly communicate with each site independently. The network engineer must configure the head office router by considering zero-touch technology when adding new sites in the same WAN infrastructure.

  Which configuration must be applied to the head office router to meet this requirement?

  A. interface Tunnel0 tunnel mode ip ip nhrp map multicast dynamic
  B. interface Tunnel0 tunnel mode dvmrp ip nhrp redirect
  C. interface Tunnel0 tunnel mode ip ip nhrp redirect
  D. interface Tunnel0 tunnel mode gre multipoint ip nhrp map multicast dynamic
  D. interface Tunnel0 tunnel mode gre multipoint ip nhrp map multicast dynamic

• Question 384:

  Which feature is used by LDP in the forwarding path within the MPLS cloud?

  A. IP forwarding
  B. TTL
  C. TDP
  D. LSP
  D. LSP

• Question 385:

  You are troubleshooting a PPPoE connection that is supposed to maintain a connection with the ISP, even if no interesting traffic exists. The configuration of the dialer interface is shown below:

  

  What command should you add to ensure the connection is maintained in the absence of interesting traffic?

  A. dialer -group
  B. dialer persistent
  C. dialer list
  D. dialer string
  B. dialer persistent

  ---

  The dialer persistent command is used to specify that the connection stays up even in the absence of interesting traffic. Interesting traffic is user-defined traffic that triggers a call to the remote end. Were it present in the configuration, the section would appear as follows:

  

  The dialer-group command is assigns the dialer interface to a dialer group. It is an optional setting, and does not appear in this configuration.

  The dialer-list command is used to specify an access list that defines interesting traffic. It is an optional setting, and would NOT be a part of a configuration that does not maintain the connection based on interesting traffic. If you use dialer persistent, then you don't need to use dialer-list. The dialer list defines interesting traffic, while dialer persist keep the connection up in the absence of interesting traffic.

  The dialer string command is used to define the number to call to make the connection. It is present in the configuration in the scenario, and specifies the number 713 555 0199.

  Layer 2 Technologies

  Sub-Objective:

  Configure and verify PPP

  A. access-list 120 permit eigrp any host 224.0.0.10
  B. access-list 120 permit ospf any
  C. access-list 120 permit udp any any eq pim-auto-rp
  D. access-list 120 permit tcp any gt 1024 eq bgp log
  D. access-list 120 permit tcp any gt 1024 eq bgp log
