Q51. - (Topic 5) 

A company has placed a networked PC in a lobby so guests can have access to the corporate directory. 

A security concern is that someone will disconnect the directory PC and re-connect their laptop computer and have access to the corporate network. For the port servicing the lobby, which three configuration steps should be performed on the switch to prevent this? (Choose three.) 

A. Enable port security. 

B. Create the port as a trunk port. 

C. Create the port as an access port. 

D. Create the port as a protected port. 

E. Set the port security aging time to 0. 

F. Statically assign the MAC address to the address table. 

G. Configure the switch to discover new MAC addresses after a set time of inactivity. 

Answer: A,C,F 

Explanation: 

If port security is enabled and the port is only designated as access port, and finally static MAC address is assigned, it ensures that even if a physical connection is done by taking out the directory PC and inserting personal laptop or device, the connection cannot be made to the corporate network, hence ensuring safety. 


Q52. - (Topic 5) 

An administrator has connected devices to a switch and, for security reasons, wants the dynamically learned MAC addresses from the address table added to the running configuration. 

What must be done to accomplish this? 

A. Enable port security and use the keyword sticky. 

B. Set the switchport mode to trunk and save the running configuration. 

C. Use the switchport protected command to have the MAC addresses added to the configuration. 

D. Use the no switchport port-security command to allow MAC addresses to be added to the configuration. 

Answer:

Explanation:

/port_sec.pdf 

One can configure MAC addresses to be sticky. These can be dynamically learned or manually configured, stored in the address table, and added to the running configuration. If these addresses are saved in the configuration file, the interface does not need to dynamically relearn them when the switch restarts, hence enabling security as desired. 


Q53. - (Topic 3) 

Refer to the exhibit. 

Why are two OSPF designated routers identified on Core-Router? 

A. Core-Router is connected to more than one multi-access network. 

B. The router at 208.149.23.130 is a secondary DR in case the primary fails. 

C. Two router IDs have the same OSPF priority and are therefore tied for DR election 

D. The DR election is still underway and there are two contenders for the role. 

Answer:

Explanation: 

OSPF elects one DR per multi-access network. In the exhibit there are two DR so there must have more than one multi-access network. 


Q54. - (Topic 5) 

Refer to the exhibit. 

Serial 0/0 does not respond to a ping request from a host on the FastEthernet 0/0 LAN. How can this problem be corrected? 

A. Enable the Serial 0/0 interface. 

B. Correct the IP address for Serial 0/0. 

C. Correct the IP address for FastEthernet 0/0 

D. Change the encapsulation type on Serial 0/0 

E. Enable autoconfiguration on the Serial 0/0 interface 

Answer:

Explanation: 

Serial 0/0 interface is administratively down therefore, you will have to run the "no shutdown" command to enable the interface for data. 


Q55. - (Topic 1) 

Refer to the exhibit. 

A network device needs to be installed in the place of the icon labeled Network Device to accommodate a leased line attachment to the Internet. Which network device and interface configuration meets the minimum requirements for this installation? 

A. a router with two Ethernet interfaces 

B. a switch with two Ethernet interfaces 

C. a router with one Ethernet and one serial interface 

D. a switch with one Ethernet and one serial interface 

E. a router with one Ethernet and one modem interface 

Answer:

Explanation: 

Only a router can terminate a leased line attachment access circuit, and only a router can connect two different IP networks. Here, we will need a router with two interfaces, one serial connection for the line attachment and one Ethernet interface to connect to the switch on the LAN. 


Q56. DRAG DROP - (Topic 4) 

Drag the definition on the left to the correct term on the right. Not all definitions on the left will be used. 

Answer: 


Q57. - (Topic 3) 

What is the default administrative distance of OSPF? 

A. 90 

B. 100 

C. 110 

D. 120 

Answer:

Explanation: 

Administrative distance is the feature that routers use in order to select the best path when there are two or more different routes to the same destination from two different routing protocols. Administrative distance defines the reliability of a routing protocol. Each routing protocol is prioritized in order of most to least reliable (believable) with the help of an administrative distance value.

This table lists the administrative distance default values of the protocols that Cisco supports: 


Q58. - (Topic 3) 

Refer to the exhibit. 

The internetwork is using subnets of the address 192.168.1.0 with a subnet mask of 

255.255.255.224. The routing protocol in use is RIP version 1. Which address could be assigned to the FastEthernet interface on RouterA? 

A. 192.168.1.31 

B. 192.168.1.64 

C. 192.168.1.127 

D. 192.168.1.190 

E. 192.168.1.192 

Answer:

Explanation: 

Subnet mask 255.255.255.224 with CIDR of /27 which results in 32 hosts per. 

192.168.1.31 is the broadcast address for sunbet '0' 

192.168.1.64 is the network address for subnet '2' 

192.168.1.127 is the broadcast address for subnet '3' 

192.168.1.192 is the network address for subnet '6' 


Q59. - (Topic 5) 

Refer to the exhibit. 

The network administrator made the entries that are shown and then saved the configuration. From a console connection, what password or password sequence is required for the administrator to access privileged mode on Router1? 

A. cisco 

B. sanfran 

C. sanjose 

D. either cisco or sanfran 

E. either cisco or sanjose 

F. sanjose and sanfran 

Answer:

Explanation: 

The enable secret password takes precedence over the enable password, so sanfran will be used. 


Q60. - (Topic 1) 

Which OSI layer header contains the address of a destination host that is on another network? 

A. application 

B. session 

C. transport 

D. network 

E. data link 

F. physical 

Answer:

Explanation: 

Only network address contains this information. To transmit the packets the sender uses network address and datalink address. But the layer 2 address represents just the address of the next hop device on the way to the sender. It is changed on each hop. Network address remains the same.
