Cisco CCNP Enterprise 300-410 Questions & Answers

• Question 1:

  Refer to the exhibit.

  

  The server for the finance department is not reachable consistently on the 200.30.40.0/24 network and after every second month it gets a new IP address. Which two actions must be taken to resolve this Issue? (Choose two.)

  A. Configure the server to use DHCP on the network with default gateway 200 30.40.100.

  B. Configure the server with a static IP address and default gateway.

  C. Configure the router to exclude a server IP address.

  D. Configure the server to use DHCP on the network with default gateway 200 30.30.100.

  E. Configure the router to exclude a server IP address and default gateway.

  Correct Answer: BC

• Question 2:

  Refer to the exhibit.

  

  An engineer has configured DMVPN on a spoke router.

  What is the WAN IP address of another spoke router within the DMVPN network?

  A. 172.18.46.2

  B. 192.168.1.4

  C. 172.18.16.2

  D. 192.168.1.1

  Correct Answer: A

  From the output we can see there are 2 NHRP Peers. The first one with the NBMA Address of 172.18.16.2 and the "Attribute" (Attrb) of Static (S) so we can deduce it is the Hub device. Therefore the second one must be the remaining Spoke device with the attribute of Dynamic (D).

• Question 3:

  An engineer is configuring a network and needs packets to be forwarded to an interface for any destination address that is not in the routing table. What should be configured to accomplish this task?

  A. set ip next-hop

  B. set ip default next-hop

  C. set ip next-hop recursive

  D. set ip next-hop verify-availability

  Correct Answer: B

  The set ip default next-hop command verifies the existence of the destination IP address in the routing table, and...

  1.

  if the destination IP address exists, the command does not policy route the packet, but forwards the packet based on the routing table.

  2.

  if the destination IP address does not exist, the command policy routes the packet by sending it to the specified next hop.

• Question 4:

  Which protocol does MPLS use to support traffic engineering?

  A. Tag Distribution Protocol

  B. Resource Reservation Protocol (RSVP)

  C. Border Gateway Protocol

  D. Label Distribution Protocol

  Correct Answer: B

  MPLS TE provides a way to integrate TE capabilities (such as those used on Layer 2 protocols like ATM) into Layer 3 protocols (IP). MPLS TE uses an extension to existing protocols (Intermediate System-to- Intermediate System (IS-IS), Resource Reservation Protocol (RSVP), OSPF) to calculate and establish unidirectional tunnels that are set according to the network constraint, Traffic flows are mapped on the different tunnels depending on their destination.

• Question 5:

  Refer to the exhibit.

  

  A network engineer for AS64512 must remove the inbound and outbound traffic from link A during maintenance without closing the BGP session so that there is still a backup link over link A toward the ASN. Which BGP configuration on R1 accomplishes this goal?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

  Local preference is used to choose the path to external BGP neighbors. An example of using local-preference is shown below:

  

  In this case all BGP prefixes advertised via Link B will have a local preference of 200, which is higher than the default value (100) so Link B is preferred over Link A to send traffic.

• Question 6:

  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.

  Correct Answer: D

• Question 7:

  Refer to the exhibits.

  

  To provide reachability to network 10.1.1.0/24 from R5, the network administrator redistributes EIGRP into OSPF on R3 but notices that R4 is now taking a suboptimal path through R5 to reach 10.1.1.0/24 network. Which action fixes the issue while keeping the reachability from R5 to 10.1.1.0/24 network?

  A. Change the administrative distance of the external EIGRP to 90.

  B. Apply the outbound distribution list on R5 toward R4 in OSPF.

  C. Change the administrative distance of OSPF to 200 on R5.

  D. Redistribute OSPF into EIGRP on R4.

  Correct Answer: A

• Question 8:

  Which IGPs are supported by the MPLS LDP autoconfiguration feature?

  A. RIPv2 and OSPF

  B. OSPF and EIGRP

  C. OSPF and ISIS

  D. ISIS and RIPv2

  Correct Answer: C

  The MPLS LDP Autoconfiguration feature enables you to globally enable Label Distribution Protocol (LDP) on every interface associated with an Interior Gateway Protocol (IGP) instance. This feature is supported on Open Shortest Path First (OSPF) and Intermediate System-to-Intermediate System (IS-IS) IGPS.

• Question 9:

  An engineer needs dynamic routing between two routers and is unable to establish OSPF adjacency. The output of the show ip ospf neighbor command shows that the neighbor state is EXSTART/EXCHANGE. Which action should be taken to resolve this issue?

  A. match the passwords

  B. match the hello timers

  C. match the MTUs

  D. match the network types

  Correct Answer: C

  The problem occurs most frequently when attempting to run OSPF between a Cisco router and another vendor's router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces don't match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighboring router ignores the packet.

• Question 10:

  Refer to the exhibit.

  

  An IT staff member comes into the office during normal office hours and cannot access devices through SSH Which action should be taken to resolve this issue?

  A. Modify the access list to use the correct IP address.

  B. Configure the correct time range.

  C. Modify the access list to correct the subnet mask

  D. Configure the access list in the outbound direction.

  Correct Answer: A

  To ACL should be permit tcp 101 10.1.1.1 0.0.0.0
