Cisco 300-410 Online Questions & Answers

• Question 631:

  Refer to the exhibit.

  

  R1 cannot establish a neighbor relationship with R2. Which action resolves the issue?

  A. Configure the mtu ignore command on the interfaces of R1 and R2.
  B. Configure the ip ospf network point-to-point command on the interfaces of R1 and R2.
  C. Configure the neighbor 2.2.2.2 command on R1 under the OSPF process.
  D. Configure the ip ospf network broadcast command on the interfaces of R1 and R2.
  A. Configure the mtu ignore command on the interfaces of R1 and R2.

• Question 632:

  A network administrator must optimize the segment size of the TCP packet on the DMVPN IPsec protected tunnel interface, which carries application traffic from the head office to a designated branch. The TCP segment size must not overwhelm the MTU of the outbound link.

  Which configuration must be applied to the router to improve the application performance?

  A. interface tunnel30 ip mtu 1400 ip tcp payload-size 1360 ! crypto ipsec fragmentation before-encryption
  B. interface tunnel30 ip mtu 1400 ip tcp adjust-mss 1360 ! crypto ipsec fragmentation after-encryption
  C. interface tunnel30 ip mtu 1400 ip tcp max-segment 1360 ! crypto ipsec fragmentation before-encryption
  D. interface tunnel30 ip mtu 1400 ip tcp packet-size 1360 ! crypto ipsec fragmentation after-encryption
  B. interface tunnel30 ip mtu 1400 ip tcp adjust-mss 1360 ! crypto ipsec fragmentation after-encryption

• Question 633:

  DRAG DROP

  Drag and drop the MPLS VPN device types from me left onto the definitions on the right.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  + device in the enterprise network that connects to other customer devices: Customer (C) device

  + device in the core of the provider network that switches MPLS packets: Provider (P) device

  + device that attaches and detaches the VPN labels to the packets in the provider network: PEdevice

  + device at the edge of the enterprise network that connects to the SP network: CE device

• Question 634:

  Refer to the exhibit.

  

  An engineer configures SW101 to send OSPFv3 interfaces state change messages to the server. However, only some OSPFv3 errors are being recorded. Which organization resolves the ..?

  A. snmp-server enable traps ospfv3 state-change if-state-change
  B. snmp-server-enable traps ospfv3 state-change restart-status-change
  C. snmp-server-enable traps ospfv3 state-change neighbor-state-change.
  D. snmp-server-enable traps ospfv3 state-change if-state-change neighbor-state-change
  D. snmp-server-enable traps ospfv3 state-change if-state-change neighbor-state-change

• Question 635:

  Which router translates the customer routing information into VPNv4 routes to exchange VPNv4 routes with other devices through MP-BGP?

  A. PE
  B. CE
  C. P
  D. VPNv4 RR
  A. PE

• Question 636:

  IPV6 is enabled in the infrastructure to support customers with an IPv6 network over WAN and to connect the head office to branch offices in the local network. One of the customers is already running IPv6 and wants to enable IPv6 over the DMVPN network infrastructure between the headend and branch sites. Which configuration command must be applied to establish an mGRE IPV6 tunnel neighborship?

  A. ipv6 unicast-routing
  B. tunnel mode gre multipoint ipv6
  C. ipv6 nhrp holdtime 30
  D. tunnel protection mode ipv6
  B. tunnel mode gre multipoint ipv6

• Question 637:

  The IPv6 network is under attack by an unknown source that is neither in the binding table nor learned through neighbor discovery. Which feature helps prevent the attack?

  A. IPv6 Destination Guard
  B. IPv6 Prefix Guard
  C. IPv6 Router Advertisement Guard
  D. IPv6 Snooping
  B. IPv6 Prefix Guard

  ---

  The IPv6 Prefix Guard feature works within the IPv6 Source Guard feature and enables a device to reject traffic originating from addresses that are topologically incorrect.

• Question 638:

  Refer to the exhibit.

  

  Which two actions should be taken to access the server? (Choose two.)

  A. Modify the access list to add a second line of permit ip any
  B. Modify the access list to deny the route to 192.168.2.2.
  C. Modify distribute list seq 10 to permit the route to 192.168.2.2.
  D. Add a sequence 20 in the route map to permit access list 1.
  E. Add a floating static route to reach to 192.168.2.2 with administrative distance higher than OSPF
  B. Modify the access list to deny the route to 192.168.2.2.
  E. Add a floating static route to reach to 192.168.2.2 with administrative distance higher than OSPF

• Question 639:

  Refer to the exhibit.

  

  A loop occurs between R1, R2, and R3 while EIGRP is run with poison reverse enabled. Which action prevents the loop between R1, R2, and R3?

  A. Configure route tagging.
  B. Enable split horizon.
  C. Configure R3 as stub receive-only.
  D. Configure route filtering.
  B. Enable split horizon.

  ---

  In Cisco devices, split horizon is always used along with poison reverse (via the command "ip split-horizon") so in this question split horizon is already turned on. To prevent loop we can only use route filtering.

• Question 640:

  Refer to the exhibit.

  

  R1 is being monitored using SNMP and monitoring devices are getting only partial information. What action should be taken to resolve this issue?

  A. Modify the CoPP policy to increase the configured exceeded limit for SNMP.
  B. Modify the access list to include snmptrap.
  C. Modify the CoPP policy to increase the configured CIR limit for SNMP.
  D. Modify the access list to add a second line to allow udp any any eq snmp.
  B. Modify the access list to include snmptrap.
