Cisco 300-410 Online Questions & Answers

• Question 111:

  Refer to the exhibit. Users report that IP addresses cannot be acquired from the DHCP server. The DHCP server is configured as shown. About 300 total nonconcurrent users are using this DHCP server, but none of them are active for more than two hours per day. Which action fixes the issue within the current resources?

  

  A. Modify the subnet mask to the network 192.168.1.0 255.255.254.0 command in the DHCP pool
  B. Configure the DHCP lease time to a smaller value
  C. Configure the DHCP lease time to a bigger value
  D. Add the network 192.168.2.0 255.255.255.0 command to the DHCP pool
  B. Configure the DHCP lease time to a smaller value

• Question 112:

  SIMULATION Tasks A network is configured with CoPP to protect the CORE router route processor for stability and DDoS protection. As a company policy, a class named class-default is preconfigured and must not be modified or deleted. Troubleshoot CoPP to resolve the issues introduced during the maintenance window to ensure that:

  1. Dynamic routing policies are under CoPP-CRITICAL and are allowed only from the 10.10.x.x range.

  2. Telnet, SSH, and ping are under CoPP-IMPORTANT and are allowed strictly to/from 10.10.x.x to the CORE router (Hint: you can verify using Loopback1).

  3. All devices ping (UDP) any CORE router interface successfully to/from the 10.10.x.x range and do not allow any other IP address.

  4. All devices run a successful traceroute (UDP) to any interface on the CORE router to/from the 10.10.x.x range, are under CoPP-NORMAL, and do not allow any other IP address traceroute is to be under CoPP-NORMAL (Hint: Traceroute port range 33434 33464).

• Question 113:

  Refer to the Exhibit. A network administrator added one router in the Cisco DNA Center and checked its discovery and health from the Network Health Dashboard. The network administratorobserved that the router is still showing up as unmonitored.

  

  What must be configured on the router to mount it in the Cisco DNA Center?

  A. Configure router with NetFlow data
  B. Configure router with the telemetry data
  C. Configure router with routing to reach Cisco DNA Center
  D. Configure router with SNMPv2c or SNMPv3 traps
  C. Configure router with routing to reach Cisco DNA Center

• Question 114:

  Refer to the exhibit. Routing protocols are mutually redistributed on R3 and R1. Users report intermittent connectivity to services hosted on the 10.1.1.0/24 prefix. Significant routing update changes are noticed on R3 when the show ip route profile command is run. How must the services be stabilized?

  

  A. The issue with using BGP must be resolved by using another protocol and redistributing it into EIGRP on R3
  B. The routing loop must be fixed by reducing the admin distance of iBGP from 200 to 100 on R3
  C. The routing loop must be fixed by reducing the admin distance of OSPF from 110 to 80 on R3
  D. The issue with using iBGP must be fixed by running eBGP between R3 and R4
  B. The routing loop must be fixed by reducing the admin distance of iBGP from 200 to 100 on R3

  ---

  After redistribution, R3 learns about network 10.1.1.0/24 via two paths:+ Internal BGP (IBGP):

  advertised from R4 with AD of 200 (and metric of 0)+ OSPF: advertised from R1 with AD of 110 (O E2) (and metric of 20)Therefore R3 will choose the path with the lower AD via OSPF But this is a looped path which is received from R3 -> R2 -> R1 -> R3. So when the advertised route from R4 is expired, the looped path is also expired soon and R3 willreinstall the main path from R4. This is the cause of intermittent connectivity.In order to solve this issue, we can lower the AD of iBGP to a value which is lower

  than 110 so that it is preferred over OSPF-advertised route.

• Question 115:

  Which command can you use to display the area border routers (ABRs) and the routes to them?

  A. show ip ospf dr
  B. show ip opsf bdr
  C. show ip ospf database
  D. show ip ospf border-routers
  D. show ip ospf border-routers

  ---

  The correct answer is show ip ospf border-routers. The following commands are available to verify OSPF configurations:

  show ip ospf border-routers - displays internal ISPF routing table entries for an ABR. show ip ospf virtual-links - displays the current state of OSPF virtual links. show ip ospf - displays information about the router's role and each area to which the router is connected. show ip ospf database - displays the contents of the router's topological database. Note that a number of keywords can be used with the show ip ospf database command to get specific information.

  The command show ip ospf dr is not correct because dr is not a parameter of the show ip ospf command.

  The command show ip ospf bdr is not correct because bdr is not a parameter of the show ip ospf command.

  Objective:

  Layer 3 Technologies

  Sub-Objective:

  Configure and verify network types, area types, and router types

• Question 116:

  A CoPP policy is applied for receiving SSH traffic from the WAN interface on a Cisco ISR4321 router. However, the SSH response from the router is abnormal and stuck during the high link utilization. The problem is identified as SSH traffic does not match in the ACL. Which action resolves the issue?

  A. Rate-limit SSH traffic to ensure dedicated bandwidth.
  B. Apply CoPP on the control plane interface.
  C. Increase the IP precedence value of SSH traffic to 6.
  D. Apply CoPP on the WAN interface inbound direction.
  B. Apply CoPP on the control plane interface.

  ---

  The problem is "SSH traffic does not match in the ACL" and "CoPP policy is applied for receiving SSH traffic from the WAN interface" so we should apply CoPP on the control plane interface instead.

• Question 117:

  Refer to the exhibit.

  

  Which configuration resolves the issue?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

• Question 118:

  Refer to the exhibit.

  

  While troubleshooting an EIGRP neighbor adjacency problem, the network engineer notices that the interface connected to the neighboring router is not participating in the EIGRP process. Which action resolves the issue?

  A. Configure the network command to network 172.16.0.1 0.0.0.0
  B. Configure the network command under EIGRP address family vrf CLIENT1
  C. Configure EIGRP metrics on interface FastEthernet0/3
  D. Configure the network command under EIGRP address family ipv4
  D. Configure the network command under EIGRP address family ipv4

  A. Enable Secure Shell.
  B. Enable Command Runner.

  B. R1(config)#ip vrf Inet FastEthernet0/0
  C. R1(config)# ip vrf Inet R1(config-vrf)#interface FastEthernet0/0 R1(config-if)#ip vrf forwarding Inet
  D. R1(config)#router ospf 1 vrf Inet R1(config-router)#ip vrf forwarding FastEthernet0/0
  C. R1(config)# ip vrf Inet R1(config-vrf)#interface FastEthernet0/0 R1(config-if)#ip vrf forwarding Inet
