Using Google Public DNS
Configuring your network settings to use Google Public DNS
When you use Google Public DNS, you are changing your DNS "switchboard" operator from your ISP to Google Public DNS.In most cases, the IP addresses used by your ISP's domain name servers are automatically set by your ISP via the Dynamic Host Configuration Protocol (DHCP). To use Google Public DNS, you need to explicitly change the DNS settings in your operating system or device to use the Google Public DNS IP addresses. The procedure for changing your DNS settings varies according to operating system and version (Windows, Mac or Linux) or the device (computer, phone, or router). We give general procedures here that might not apply for your OS or device; please consult your vendor documentation for authoritative information.
Note: We recommend that only users who are proficient with configuring operating system settings make these changes.
Important: Before you start
Before you change your DNS settings to use Google Public DNS, be sure to write down the current server addresses or settings on a piece of paper. It is very important that you keep these numbers for backup purposes, in case you need to revert to them at any time.After changing your settings, if you encounter a problem and cannot connect to the Internet, please call our support numbers for troubleshooting instructions.
We also recommend that you download this page and print it, in the event that you encounter a problem and need to refer to these instructions.
Google Public DNS telephone support
- 877-590-4367 in the U.S.
- 770-200-1201 outside the U.S.
Google Public DNS IP addresses
The Google Public DNS IP addresses are as follows:- 8.8.8.8
- 8.8.4.4

Which routing protocol maintains a topology table separate from the routing table?
IGRP
RIPv1
RIPv2
*EIGRP
2
Refer to the exhibit. All routers are running RIPv1. The two networks 10.1.1.0/29 and 10.1.1.16/29 are unable to access each
other. What can be the cause of this problem?
Because RIPv1 is a classless protocol, it does not support this access.
*RIPv1 does not support discontiguous networks.
RIPv1 does not support load balancing.
RIPv1 does not support automatic summarization.
www.ccna4u.org
3
Which two statements are correct about the split horizon with poison reverse method of routing loop prevention? (Choose
two.)
It is enabled by default on all Cisco IOS implementations.
*It assigns a value that represents an infinite metric to the poisoned route.
It sends back the poisoned route update to the same interface from where it was received.
It instructs routers to hold all changes that might affect routes, for a specified period of time.
*It limits the number of hops a packet can traverse through the network before it is discarded.
Holddown timers are used to prevent regular update messages from inappropriately reinstating a route that may have gone bad. The split horizon rule says that a router should not advertise a network through the interface from which the update came. Route poisoning is used to mark the route as unreachable in a routing update that is sent to other routers. The rule for split horizon with poison reverse states when sending updates out a specific interface, designate any networks that were learned on that interface as unreachable.
4
What are two reasons for the occurrence of a routing loop? (Choose two.)
slow convergence
*incorrectly configured static routes
routes that are learned via two routing protocols
*static and dynamic routing being used on the same router
lack of a default route on the router that connects to the Internet
The loop may be a result of: Incorrectly configured static routes Incorrectly configured route redistribution (redistribution is a process of handing the routing information from one routing protocol to another routing protocol and is discussed in CCNP-level courses) Inconsistent routing tables not being updated due to slow convergence in a changing network Incorrectly configured or installed discard routes
5
All routers in a network are configured in a single OSPF area with the same priority value. No loopback interface has been
set on any of the routers. Which secondary value will the routers use to determine the router ID?
The highest MAC address among the active interfaces of the network will be used.
There will be no router ID until a loopback interface is configured.
The highest IP address among the active FastEthernet interfaces that are running OSPF will be used.
*The highest IP address among the active interfaces will be used.
Determining the Router ID The OSPF router ID is used to uniquely identify each router in the OSPF routing domain. A router ID is simply an IP address. Cisco routers derive the router ID based on three criteria and with the following precedence: 1. Use the IP address configured with the OSPF router-id command. 2. If the router-id is not configured, the router chooses highest IP address of any of its loopback interfaces. 3. If no loopback interfaces are configured, the router chooses highest active IP address of any of its physical interfaces.
6
Refer to the exhibit. Although R2 is configured correctly, host A is unable to access the Internet. What are two static
routes that can be configured on R1, either of which would enable Internet connectivity for host A? (Choose two.)
ip route 0.0.0.0 0.0.0.0 Fa0/0
*ip route 0.0.0.0 0.0.0.0 Fa0/1
ip route 0.0.0.0 0.0.0.0 10.1.1.1
*ip route 0.0.0.0 0.0.0.0 10.1.1.2
ip route 209.165.202.0 255.255.255.0 10.1.1.1
7
What is the function of the OSPF LSR packet?
It is used to confirm the receipt of LSUs.
It is used to establish and maintain adjacency with other OSPF routers.
*It is used by the receiving routers to request more information about any entry in the DBD.
It is used to check the database synchronization between routers
1. Hello - Hello packets are used to establish and maintain adjacency with other OSPF routers. 2. DBD - The Database Description (DBD) packet contains an abbreviated list of the sending router's link-state database and is used by receiving routers to check against the local link-state database. 3. LSR - Receiving routers can then request more information about any entry in the DBD by sending a Link-State Request (LSR). 4. LSU - Link-State Update (LSU) packets are used to reply to LSRs as well as to announce new information. LSUs contain seven different types of Link-State Advertisements (LSAs). LSUs and LSAs are briefly discussed in a later topic. 5. LSAck - When an LSU is received, the router sends a Link-State Acknowledgement (LSAck) to confirm receipt of the LSU.
8
Refer to the exhibit. A network administrator is accessing router R1 from the console port. Once the administrator is
connected to the router, which password should the administrator enter at the R1> prompt to access the privileged EXEC
mode?
Cisco001

Cisco901
9
Which two technologies can be used in distance vector routing protocols to prevent routing loops? (Choose two.)
authentication
link-state advertisements
*hold-down timers
Spanning Tree Protocol
*split horizon
Holddown timers are used to prevent regular update messages from inappropriately reinstating a route that may have gone bad. The split horizon rule says that a router should not advertise a network through the interface from which the update came. Route poisoning is used to mark the route as unreachable in a routing update that is sent to other routers. The rule for split horizon with poison reverse states when sending updates out a specific interface, designate any networks that were learned on that interface as unreachable.
10

characteristics of this protocol? (Choose two.)
*It uses the Bellman-Ford algorithm to determine the best path.
It displays an actual map of the network topology.
It offers rapid convergence in large networks.
*It periodically sends complete routing tables to all connected devices.
It is beneficial in complex and hierarchically designed networks.
13

Refer to the exhibit. The 10.4.0.0 network fails. What mechanism prevents R2 from receiving false update information
regarding the 10.4.0.0 network?
*split horizon
hold-down timers
route poisoning
triggered updates
Holddown timers are used to prevent regular update messages from inappropriately reinstating a route that may have gone bad. The split horizon rule says that a router should not advertise a network through the interface from which the update came. Route poisoning is used to mark the route as unreachable in a routing update that is sent to other routers. The rule for split horizon with poison reverse states when sending updates out a specific interface, designate any networks that were learned on that interface as unreachable.
16
Refer to the exhibit. The routers are properly configured using a dynamic routing protocol with default settings, and the
network is fully converged. Router A is forwarding data to router E. Which statement is true about the routing path?
*If the network uses the RIP protocol, router A will determine that all paths have equal cost.
If the network uses the RIP protocol, router A will update only the A-C-E path in its routing table.
If the network uses the EIGRP routing protocol, router A will determine that path A-D-E has the lowest cost.
If both RIP and EIGRP protocols are configured on router A, the router will use the route information that is
learned by the RIP routing protocol.

Which two statements are correct about the split horizon with poison reverse method of routing loop prevention? (Choose
two.)
It is enabled by default on all Cisco IOS implementations.
*It assigns a value that represents an infinite metric to the poisoned route.
It sends back the poisoned route update to the same interface from where it was received.
It instructs routers to hold all changes that might affect routes, for a specified period of time.
*It limits the number of hops a packet can traverse through the network before it is discarded.
Holddown timers are used to prevent regular update messages from inappropriately reinstating a route that may have gone bad. The split horizon rule says that a router should not advertise a network through the interface from which the update came. Route poisoning is used to mark the route as unreachable in a routing update that is sent to other routers. The rule for split horizon with poison reverse states when sending updates out a specific interface, designate any networks that were learned on that interface as unreachable.

All routers in a network are configured in a single OSPF area with the same priority value. No loopback interface has been
set on any of the routers. Which secondary value will the routers use to determine the router ID?
The highest MAC address among the active interfaces of the network will be used.
There will be no router ID until a loopback interface is configured.
The highest IP address among the active FastEthernet interfaces that are running OSPF will be used.
*The highest IP address among the active interfaces will be used.
Determining the Router ID The OSPF router ID is used to uniquely identify each router in the OSPF routing domain. A router ID is simply an IP address. Cisco routers derive the router ID based on three criteria and with the following precedence: 1. Use the IP address configured with the OSPF router-id command. 2. If the router-id is not configured, the router chooses highest IP address of any of its loopback interfaces. 3. If no loopback interfaces are configured, the router chooses highest active IP address of any of its physical interfaces.

What is the function of the OSPF LSR packet?
It is used to confirm the receipt of LSUs.
It is used to establish and maintain adjacency with other OSPF routers.
*It is used by the receiving routers to request more information about any entry in the DBD.
It is used to check the database synchronization between routers
1. Hello - Hello packets are used to establish and maintain adjacency with other OSPF routers. 2. DBD - The Database Description (DBD) packet contains an abbreviated list of the sending router's link-state database and is used by receiving routers to check against the local link-state database. 3. LSR - Receiving routers can then request more information about any entry in the DBD by sending a Link-State Request (LSR). 4. LSU - Link-State Update (LSU) packets are used to reply to LSRs as well as to announce new information. LSUs contain seven different types of Link-State Advertisements (LSAs). LSUs and LSAs are briefly discussed in a later topic. 5. LSAck - When an LSU is received, the router sends a Link-State Acknowledgement (LSAck) to confirm receipt of the LSU.

command. However, upon running the show ip route command, the network administrator sees that the router has installed a
different route to the 192.168.6.0 network learned via EIGRP. What could be the reason for the missing RIP route?
*Compared to RIP, EIGRP has a lower administrative distance.
Compared to EIGRP, RIP has a higher metric value for the route.
Compared to RIP, the EIGRP route has fewer hops.
Compared to RIP, EIGRP has a faster update timer.

44
Which two statements are true for link-state routing protocols? (Choose two.)
*Routers that run a link-state protocol can establish a complete topology of the network. Routers in a multipoint network that run a link-state protocol can exchange routing tables.
Routers use only hop count for routing decisions.
*The shortest path first algorithm is used. Split horizon is used to avoid routing loops.
45
Refer to the exhibit. Which two components are required to complete the configuration? (Choose two.)
a crossover cable
a DCE device
*a DTE device
a modem
*a V.35 cable
46
Refer to the exhibit. The output of the show ip route command for router R1 is displayed. What action will the router take
for a packet that is destined for 192.168.1.5?
*It will drop the packet.
It will forward the packet to interface Serial0/0/0.
It will determine the route for the packet through a routing protocol.
It will forward the packet to the default gateway.
47
Refer to the exhibit. A network administrator has run the show interface command. The output of this command is
displayed. What is the first step that is required to make this interface operational?
Switch the cable with a known working cable.
*Issue the no shutdown command on the interface. Configure the interface as a loopback interface.
Set the encapsulation for the interface.
48
What are two tasks that must be completed before two routers can use OSPF to form a neighbor adjacency? (Choose two.)
The routers must elect a designated router.
*The routers must agree on the network type. *The routers must use the same dead interval.
The routers must exchange link state requests.
The routers must exchange database description packets.
49
Refer to the exhibit. All interfaces are addressed and functioning correctly. The network administrator runs the tracert
command on host A. Which two facts could be responsible for the output of this command? (Choose two.)
The gateway for Host A is missing or improperly configured.
The gateway for Host B is missing or improperly configured.
The entry for 192.168.1.0/24 is missing from the routing table of R1.
*The entry for 192.168.1.0/24 is missing from the routing table of R2. *The entry for 192.168.2.0/24 is missing from the routing table of R1. The entry for 192.168.2.0/24 is missing from the routing table of R2.
50
Refer to the exhibit. How many routes are ultimate routes?
*3
4
5
7
51
Refer to the exhibit. Which summarization should R1 use to advertise its networks to R2?
192.168.1.0/24
192.168.0.0/24
*192.168.0.0/22
192.168.1.0/22
52
How does route poisoning prevent routing loops?
New routing updates are ignored until the network has converged.
*Failed routes are advertised with a metric of infinity. A route is marked as unavailable when its Time to Live is exceeded.
The unreachable route is cleared from the routing table after the invalid timer expires.
53
What are two functions of a router? (Choose two.)
*It forwards data packets toward their destination. It forwards the packet to the destination if the TTL value is 0.
It changes the destination IP address of data packets before forwarding them to an exit interface.
It determines the best path based on the destination MAC address.
*It acts as an intersection between multiple IP networks.
54
Which two components are used to determine the router ID in the configuration of the OSPF routing process? (Choose two.)
the IP address of the first FastEthernet interface
the highest IP address of any logical interface
*the highest IP address of any physical interface the default gateway IP address
*the priority value of 1 on any physical interface
55
Refer to the exhibit. R2 is configured correctly. The network administrator has configured R1 as shown. Which two facts
are true about the forwarding of route information by R1? (Choose two.)
*R1 will forward the route information for subnet 192.168.100.0/30. *R1 will not forward route information for subnet 192.168.100.4/30. R1 will forward the route information with an administrative distance set to 50.
R1 will forward the summarized route information for network 192.168.100.0/24.
