Given the following network address translation (NAT) topology, identify the IP address that is the outside global IP address. (NOTE: To avoid using an organization's actual IP addresses in this question, all IP addresses are technically private IP addresses. However, assume that the 172.16.1.0/24 network and the 10.1.2.3 IP address are publicly routable.)

10.1.2.3

What is the administrative distance of OSPF in a Cisco network?

110

What is the administrative distance of RIP in a Cisco network?

120

Refer to the exhibit. Given the network address translation (NAT) topology, identify the IP address that is the inside global IP address. (NOTE: To avoid using an organization's actual IP addresses in this question, all IP addresses are technically private IP addresses. However, assume that the 172.16.1.0/24 network and the 10.1.2.3 IP address are publicly routable.)

172.16.1.2

A router's IP routing table has the following entries: Network Next Hop 10.0.0.0/8 10.2.2.2 10.1.0.0/16 192.168.1.2 10.1.1.0/24 172.16.1.2 0.0.0.0/0 10.3.3.2 To which next hop IP address will the router forward a packet destined for 10.1.2.1?

192.168.1.2

Refer to the exhibit. Given the network address translation (NAT) topology, identify the IP address that is the inside local IP address. (NOTE: To avoid using an organization's actual IP addresses in this question, all IP addresses are technically private IP addresses. However, assume that the 172.16.1.0/24 network and the 10.1.2.3 IP address are publicly routable.)

192.168.1.2

What is the administrative distance of internal BGP in a Cisco network?

200

Which of the following are ways routes can be injected into a router's IP routing table?

A route is directly connected. A route is statically configured. A route is redistributed from one routing source into a dynamic routing protocol. A route is dynamically learned.

What protocol is used to request a MAC address that corresponds to a known IPv4 address on the local network?

ARP

Which two routing protocols use bandwidth in their calculation of metric by default?

OSPF EIGRP

What variation of network address translation (NAT) allows multiple inside local addresses to share a single inside global address?

PAT

What loop-prevention mechanism is an override of another loop-prevention mechanism?

Poison reverse

Which of the following is a distance-vector routing protocol with a maximum usable hop count of 15?

RIP

Which of the following are examples of interior gateway protocols?

RIP IS-IS OSPF

What variation of network address translation (NAT) allows you to statically configure the inside global address assigned to a specific device inside your network?

SNAT

What routing protocol characteristic indicates the believability of the routing protocol (as opposed to other routing protocols)?

Administrative distance

What is a routing protocol that is used for moving prefixes back and forth between different autonomous systems?

BGP

Which of the following is an example of an EGP?

BGP

Which of the following routing protocols is an EGP?

BGP

Which routing protocol uses a complex set of metrics called path vectors?

BGP

SPF uses cost as a metric value. What is this cost value based on?

Bandwidth

What NAT variation automatically assigns an inside global address from a pool of available addresses?

DNAT

What variation of network address translation (NAT) automatically assigns an inside global address from a pool of available addresses?

DNAT

If a PC on an Ethernet network attempts to communicate with a host on a different subnet, what destination IP address and destination MAC address will be placed in the packet/frame header sent by the PC?

Dest. IP: IP address of remote host. Dest. MAC: MAC address of default gateway.

A Cisco router has learned a network via three different routing protocols: OSPF, EIGRP, and RIP. Which route will the router believe (that is, inject into the router's IP routing table)?

EIGRP

Which of the following routing protocols are interior gateway protocols?

EIGRP IS-IS OSPF

What does RIP use for a metric?

Hop Count

What multicast protocol is used between clients and routers to let routers know which of their interfaces are connected to a multicast receiver?

IGMP

What NAT IP address is a public IP address that maps to an inside device?

Inside global

What metric is used by the OSPF routing protocol?

cost

What type of route is manually configured in a router's routing table and tells a router where to send traffic destined for a network not in the router's routing table?

default static route

Routing protocols differ in the amount of time they require to fail over from a previously active route to a backup route. What is the name for this routing protocol property?

convergence

What loop-prevention mechanism will prevent a route from being advertised out an interface from which it was learned?
