• Question 182:

  Refer to the exhibit.

  

  A PC is configured to obtain an IP address automatically, but it receives an IP address only from the 169.254.0.0 subnet. The DHCP server logs contained no DHCPDISCOVER message from the MAC address of the PC. Which action resolves the issue?

  A. Configure a DHCP reservation on the server for the PC.
  B. Configure an ip helper-address on the router to forward DHCP messages to the server.
  C. Configure DHCP Snooping on the switch to forward DHCP messages to the server.
  D. Configure a static IP address on the PC and exclude it from the DHCP pool.
  B. Configure an ip helper-address on the router to forward DHCP messages to the server.

• Question 183:

  Refer to the exhibit. HostA and HostB cannot receive IP addresses from the DHCP server. The switches are configured with the DHCP snooping. Which configuration on SW3 resolves the issue?

  

  

  A. ip dhcp relay information option-insert
  B. no ip dhcp snooping information option
  C. ip dhcp server use subscriber-id client-id
  D. ip helper-address 1.0.0.2
  B. no ip dhcp snooping information option

• Question 184:

  What is LDP label binding?

  A. neighboring router with label
  B. source prefix with label
  C. destination prefix with label
  D. two routers with label distribution session
  C. destination prefix with label

• Question 185:

  Refer to the exhibit. An administrator is configuring a GRE tunnel to establish an EIGRP neighbor to a remote router. The other tunnel endpoint is already configured. After applying the configuration as shown, the tunnel started flapping.

  

  Which action resolves the issue?

  A. Modify the network command to use the Tunnel0 interface netmask
  B. Advertise the Loopback0 interface from R2 across the tunnel
  C. Stop sending a route matching the tunnel destination across the tunnel
  D. Readdress the IP network on the Tunnel0 on both routers using the /31 netmask
  C. Stop sending a route matching the tunnel destination across the tunnel

  ---

  In this question we are advertising the tunnel IP address 192.168.12.2 to the other side. When other end receives the EIGRP advertisement, it realizes it can reach the other side of the tunnel via EIGRP.

  In other words, it reaches the tunnel destination through the tunnel itself -> This causes "recursive routing" error.

  Note: In order to avoid this error, do not advertise the tunnel destination IP address on the tunnel interface to other side.

• Question 186:

  Refer to the exhibit. A network administrator configured mutual redistribution on R1 and R2 routers, which caused instability in the network.

  

  Which action resolves the issue?

  A. Set a tag in the route map when redistributing EIGRP into OSPF on R1, and match the same tag on R2 to deny when redistributing OSPF into EIGRP.
  B. Set a tag in the route map when redistributing EIGRP into OSPF on R1, and match the same tag on R2 to allow when redistributing OSPF into EIGRP.
  C. Advertise summary routes of EIGRP to OSPF and deny specific EIGRP routes when redistributing into OSPF.
  D. Apply a prefix list of EIGRP network routes in OSPF domain on R1 to propagate back into the EIGRP routing domain.
  A. Set a tag in the route map when redistributing EIGRP into OSPF on R1, and match the same tag on R2 to deny when redistributing OSPF into EIGRP.

• Question 187:

  Refer to the exhibit.

  

  Router DHCP is configured to lease IPv4 and IPv6 addresses to clients on ALS1 and ALS2. Clients on ALS2 receive IPv4 and IPv6 addresses. Clients on ALS1 receive IPv4 addresses. Which configuration on DSW1 allows clients on ALS1 to receive IPv6 addresses?

  

  A. DSW1(dhcp-config)# default-router 2002:A04:A01::A04:A01
  B. DSW1(config)# ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet 1/2
  C. DSW1(config)#ipv6 route 2002:404:404::404:404/128 FastEthernet 1/0
  D. DSW1(config-if)# ipv6 helper address 2002:404:404::404:404
  B. DSW1(config)# ipv6 dhcp relay destination 2002:404:404::404:404 GigabitEthernet 1/2

• Question 188:

  An engineer configured VRF-Lite on a router for VRF blue and VRF red. OSPF must be enabled on each VRF to peer to a directly connected router in each VRF. Which configuration forms OSPF neighbors over the network 10.10.10.0/28 for VRF blue and 192.168.0.0/30 for VRF red?

  A. router ospf 1 vrf blue network 10.10.10.0 0.0.0.252 area 0 router ospf 2 vrf red network 192.168.0.0 0.0.0.240 area 0
  B. router ospf 1 vrf blue network 10.10.10.0 0.0.0.15 area 0 router ospf 2 vrf red network 192.168.0.0 0.0.0.3 area 0
  C. router ospf 1 vrf blue network 10.10.10.0 0.0.0.240 area 0 router ospf 2 vrf red network 192.168.0.0 0.0.0.252 area 0
  D. router ospf 1 vrf blue network 10.10.10.0 0.0.0.3 area 0 router ospf 2 vrf red network 192 168.0.0 0.0.0.15 are 0
  B. router ospf 1 vrf blue network 10.10.10.0 0.0.0.15 area 0 router ospf 2 vrf red network 192.168.0.0 0.0.0.3 area 0

• Question 189:

  You have a Frame Relay topology that is currently a hub and spoke using a single physical serial interface on the hub router with the default network type. OSPF is also running on the interface.

  You execute the following command:

  ip ospf network point-to-point

  What would be the effect of executing this command on the serial interface of the hub router?

  A. The hello interval for OSPF will change to 30 seconds
  B. The dead interval for OSPF will change to 40 seconds
  C. There will now be a DR election
  D. The hub router must now be configured with a router ID
  B. The dead interval for OSPF will change to 40 seconds

  ---

  The dead interval for OSPF will change to 40 seconds. By default, a Frame Relay connection that uses a physical interface is designated a non-broadcast network for purposes of determining the OSPF hello and dead intervals. There are four possible network types for Frame Relay, and they use different values for the OSPF hello and dead intervals. The values are shown below:

  

  When the ip ospf network point-to-point command is executed, it will change the network type from the default of non-broadcast to point-to-point. This alteration will change the hello and dead intervals to 10 and 40 seconds, respectively.

  The hello interval for OSPF will not change to 30 seconds. That is the value for non-broadcast and point-to- multipoint networks.

  There will not be a designated router (DR) election. DRs are not elected on a point-to-point network. The hub router does not need to be configured with a router ID. In OSPF for IPv4, the router can create its own by using one of the IP addresses of its interfaces.
