Q31. - (Topic 7) 

Which statement about the inside interface configuration in a NAT deployment is true? 

A. It is defined globally 

B. It identifies the location of source addresses for outgoing packets to be translated using access or route maps. 

C. It must be configured if static NAT is used 

D. It identifies the public IP address that traffic will use to reach the internet. 

Answer:

Explanation: 

This module describes how to configure Network Address Translation (NAT) for IP address conservation and how to configure inside and outside source addresses. This module also provides information about the benefits of configuring NAT for IP address conservation. NAT enables private IP internetworks that use nonregistered IP addresses to connect to the Internet. NAT operates on a device, usually connecting two networks, and translates the private (not globally unique) addresses in the internal network into legal addresses before packets are forwarded onto another network. NAT can be configured to advertise to the outside world only one address for the entire network. This ability provides additional security by effectively hiding the entire internal network behind that one address. NAT is also used at the enterprise edge to allow internal users access to the Internet and to allow Internet access to internal devices such as mail servers. 


Q32. - (Topic 3) 

Refer to the exhibit. 

The two routers have had their startup configurations cleared and have been restarted. At a minimum, what must the administrator do to enable CDP to exchange information between R1 and R2? 

A. Configure the router with the cdp enable command. 

B. Enter no shutdown commands on the R1 and R2 fa0/1 interfaces. 

C. Configure IP addressing and no shutdown commands on both the R1 and R2 fa0/1 interfaces. 

D. Configure IP addressing and no shutdown commands on either of the R1 or R2 fa0/1 interfaces. 

Answer:

Explanation: 

If the no shut down commands are not entered, then CDP can exchange information between the two routers. By default, all Cisco device interfaces and ports are shut down and need to be manually enabled. 


Q33. - (Topic 3) 

Which router command will configure an interface with the IP address 10.10.80.1/19? 

A. router(config-if)# ip address 10.10.80.1/19 

B. router(config-if)# ip address 10.10.80.1 255.255.0.0 

C. router(config-if)# ip address 10.10.80.1 255.255.255.0 

D. router(config-if)# ip address 10.10.80.1 255.255.224.0 

E. router(config-if)# ip address 10.10.80.1 255.255.240.0 

F. router(config-if)# ip address 10.10.80.1 255.255.255.240 

Answer:

Explanation: 

255.255.224 equal /19 in CIDR format hence the answer 


Q34. - (Topic 7) 

Which statement about a router on a stick is true? 

A. Its date plane router traffic for a single VI AN over two or more switches. 

B. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs on the same subnet. 

C. It requires the native VLAN to be disabled. 

D. It uses multiple subinterfaces of a single interface to encapsulate traffic for different VLANs.

Q35. - (Topic 3) 

Refer to the exhibit. 

The enterprise has decided to use the network address 172.16.0.0. The network administrator needs to design a classful addressing scheme to accommodate the three subnets, with 30, 40, and 50 hosts, as shown. What subnet mask would accommodate this network? 

A. 255.255.255.192 

B. 255.255.255.224 

C. 255.255.255.240 

D. 255.255.255.248 

E. 255.255.255.252 

Answer:

Explanation: 

Subnet mask A i.e. 255.255.255.192 with CIDR of /26 which means 64 hosts per subnet which are sufficient to accommodate even the largest subnet of 50 hosts.

Q36. - (Topic 7) 

Which component of the routing table ranks routing protocols according to their preferences? 

A. administrative distance 

B. next hop 

C. metric 

D. routing protocol code 

Answer:

Explanation: 

Administrative distance - This is the measure of trustworthiness of the source of the 

route. If a router learns about a destination from more than one routing protocol, 

administrative distance is compared and the preference is given to the routes with lower 

administrative distance. In other words, it is the believability of the source of the route. 


Q37. - (Topic 1) 

A workstation has just resolved a browser URL to the IP address of a server. What protocol will the workstation now use to determine the destination MAC address to be placed into frames directed toward the server? 

A. HTTP 

B. DNS 

C. DHCP 

D. RARP 

E. ARP 

Answer:

Explanation: 

The RARP protocol is used to translate hardware interface addresses to protocol addresses. The RARP message format is very similar to the ARP format. When the booting computer sends the broadcast ARP request, it places its own hardware address in both the sending and receiving fields in the encapsulated ARP data packet. The RARP server will fill in the correct sending and receiving IP addresses in its response to the message. This way the booting computer will know its IP address when it gets the message from the RARP server 


Q38. - (Topic 1) 

Refer to the exhibit. 

If host A sends an IP packet to host B, what will the source physical address be in the frame when it reaches host B? 

A. 10.168.10.99 

B. 10.168.11.88 

C. A1:A1:A1:A1:A1:A1 

D. B2:B2:B2:B2:B2:B2 

E. C3:C3:C3:C3:C3:C3 

F. D4:D4:D4:D4:D4:D4 

Answer:

Explanation: 

When packets transfer from one host to another across a routed segment, the source IP address always remains the same source IP address, and the source physical (MAC) address will be the existing router’s interface address. Similarly, the destination IP address always remains the same and the destination physical (MAC) address is the destination router’s interface address. 


Q39. - (Topic 3) 

Scenario 

Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links. 

You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the main office and the routers located in the remote branch offices. 

R1 does not form an OSPF neighbor adjacency with R2. Which option would fix the issue? 

A. R1 ethernetO/1 is shutdown. Configure no shutdown command. 

B. R1 ethernetO/1 configured with a non-default OSPF hello interval of 25: configure no ip ospf hello-interval 25 

C. R2 ethernetO/1 and R3 ethernetO/O are configured with a non-default OSPF hello interval of 25; configure no ip ospf hello-interval 25 

D. Enable OSPF for R1 ethernetO/1; configure ip ospf 1 area 0 command under ethernetO/1 

Answer:

Explanation: 

Looking at the configuration of R1, we see that R1 is configured with a hello interval of 25 on interface Ethernet 0/1 while R2 is left with the default of 10 (not configured). 


Q40. - (Topic 1) 

At which layer of the OSI model does the protocol that provides the information that is displayed by the show cdp neighbors command operate? 

A. application 

B. transport 

C. network 

D. physical 

E. data link 

Answer:

Explanation: 

CDP is a device discovery protocol that runs over Layer 2 (the data link layer) on all Cisco-manufactured devices (routers, bridges, access servers, and switches) and allows network management applications to discover Cisco devices that are neighbors of already known devices. With CDP, network management applications can learn the device type and the Simple Network Management Protocol (SNMP) agent address of neighboring devices running lower-layer, transparent protocols. CDP allows devices to share basic configuration information without even configuring any protocol specific information and is enabled by default on all interfaces. CDP is a Datalink Protocol occurring at Layer 2 of the OSI model. CDP is not routable and can only go over to directly connected devices. CDP is enabled, by default, on all Cisco devices. CDP updates are generated as multicasts every 60 seconds with a hold-down period of 180 seconds for a missing neighbor. The no cdp run command globally disables CDP, while the no cdp enable command disables CDP on an interface. Use show cdp neighbors to list out your directly connected Cisco neighboring devices. Adding the detail parameter will display the layer-3 addressing configured on the neighbor.
