  1. 1. CCNA 2 Chapter 2 v5.0 answers 1. Which interface is the default location that would contain the IP address used to manage a 24port Ethernet switch? interface connected to the default gateway Fa0/1 VLAN 99 Visit Fa0/0 VLAN 1 _____________________________________________ 2. Which three statements are true about using full-duplex Fast Ethernet? (Choose three.) Performance is improved because the collision detect function is disabled on the device. Performance is improved because the NIC is able to detect collisions. Full-duplex Fast Ethernet offers 100 percent efficiency in both directions. Nodes operate in full-duplex with unidirectional data flow. Performance is improved with bidirectional data flow. Latency is reduced because the NIC processes frames faster. _____________________________________________ 3 What impact does the use of the mdix auto configuration command have on an Ethernet interface on a switch? automatically detects interface speed automatically assigns the first detected MAC address to an interface automatically detects duplex settings automatically detects copper cable type Visit _____________________________________________ 4. Which type of cable does a network administrator need to connect a PC to a switch to recover it after the Cisco IOS software fails to load? a coaxial cable a crossover cable a console cable a straight-through cable _____________________________________________ 5 While troubleshooting a connectivity problem, a network administrator notices that a switch port status LED is alternating between green and amber. What could this LED indicate? The port has an active link with normal traffic activity. The port is administratively down. The port is experiencing errors. The port has no link. A PC is using the wrong cable to connect to the port. ______________________________________________ 6 A production switch is reloaded and finishes with a Switch> prompt. What two facts can be determined? (Choose two.) The boot process was interrupted. http://ccnav5.com http://ccnav5.com Visit http://ccnav5.com
  2. 2. There is not enough RAM or flash on this router. A full version of the Cisco IOS was located and loaded. POST occurred normally. The switch did not locate the Cisco IOS in flash, so it defaulted to ROM. _______________________________________________ 7 Which command displays information about the auto-MDIX setting for a specific interface?? show running-config show controllers show processes show interfaces ___________________________________________ 8. Visit http://ccnav5.com 2-Q8 Refer to the exhibit. What media issue might exist on the link connected to Fa0/1 based on the show interface command? The interface might be configured as half-duplex. There could be too much electrical interference and noise on the link. There could be an issue with a faulty NIC. The cable attaching the host to port Fa0/1 might be too long. The bandwidth parameter on the interface might be too high. ____________________________________________ 9. 2-Q9 Refer to the exhibit. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed configuration to satisfy the requirement? Use SSH version 1. Reconfigure the RSA key. Configure SSH on a different line. Modify the transport input command. __________________________________________________ 10 Which protocol or service sends broadcasts containing the Cisco IOS software version of the sending device, and the packets of which can be captured by malicious hosts on the network? DHCP Visit SSH DNS CDP __________________________________________________ http://ccnav5.com
  3. 3. 11 In which type of attack does a malicious node request all available IP addresses in the address pool of a DHCP server in order to prevent legitimate hosts from obtaining network access?? DHCP snooping MAC address flooding CAM table overflow DHCP starvation _______________________________________________ 12 Which method would mitigate a MAC address flooding attack? using ACLs to filter broadcast traffic on the switch? increasing the speed of switch ports Visit increasing the size of the CAM table configuring port security _____________________________________ 13 Which two basic functions are performed by network security tools? (Choose two.) http://ccnav5.com simulating attacks against the production network to determine any existing vulnerabilities writing a security policy document for protecting networks educating employees about social engineering attacks revealing the type of information an attacker is able to gather from monitoring network traffic controlling physical access to user devices _______________________________________ 14 Which action will bring an error-disabled switch port back to an operational state? Issue the switchport mode access command on the interface. Issue the shutdown and then no shutdown interface commands. Remove and reconfigure port security on the interface. Clear the MAC address table on the switch. ________________________________________________ 15. Visit http://ccnav5.com 2-Q15 Refer to the exhibit. Which S1 switch port interface or interfaces should be configured with the ipdhcp snooping trust command if best practices are implemented? only the G0/2, G0/3, and G0/4 ports only the G0/1 and G0/24 ports only the G0/1, G0/2, G0/3, and G0/4 ports only unused ports only the G0/1 port _____________________________________
  4. 4. 16. 16 Visit http://ccnav5.com Refer to the exhibit. Port Fa0/2 has already been configured appropriately. The IP phone and PC work properly. Which switch configuration would be most appropriate for port Fa0/2 if the network administrator has the following goals? No one is allowed to disconnect the IP phone or the PC and connect some other wired device. If a different device is connected, port Fa0/2 is shut down. The switch should automatically detect the MAC address of the IP phone and the PC and add those addresses to the running configuration. SWA(config-if)# switchport port-security mac-address sticky SWA(config-if)# switchport port-security maximum 2 SWA(config-if)# switchport port-security SWA(config-if)# switchport port-security maximum 2 SWA(config-if)# switchport port-security mac-address sticky SWA(config-if)# switchport port-security violation restrict SWA(config-if)# switchport port-security SWA(config-if)# switchport port-security mac-address sticky SWA(config-if)# switchport port-security SWA(config-if)# switchport port-security maximum 2 SWA(config-if)# switchport port-security mac-address sticky _____________________________________________ 17. Visit http://ccnav5.com 2-Q17 Refer to the exhibit. What can be determined about port security from the information that is shown? The port has been shut down. The port has the maximum number of MAC addresses that is supported by a Layer 2 switch port which is configured for port security. The port violation mode is the default for any port that has port security enabled. The port has two attached devices. __________________________________________ 18. 2-Q18 Refer to the exhibit. Which event will take place if there is a port security violation on switch S1 interface Fa0/1? The interface will go into error-disabled state. Packets with unknown source addresses will be dropped.
  5. 5. http://ccnav5.com Visit A syslog message is logged. A notification is sent. __________________________________________ 19 The network administrator enters the following commands on a Cisco switch: Switch(config)# interface vlan1 Switch(config-if)# ip address 192.168.1.2 255.255.255.0 Switch(config-if)# no shutdown What is the effect of entering these commands? All devices attached to this switch must be in the 192.168.1.0/24 subnet to communicate. The address of the default gateway for this LAN is 192.168.1.2/24. Users on the 192.168.1.0/24 subnet are able to ping the switch at IP address 192.168.1.2. The switch is able to forward frames to remote networks. ________________________________________ 20 Which two statements are true regarding switch port security? (Choose two.) The three configurable violation modes all require user intervention to re-enable ports. The three configurable violation modes all log violations via SNMP. After entering the sticky parameter, only MAC addresses subsequently learned are converted to secure MAC addresses. If fewer than the maximum number of MAC addresses for a port are configured statically, dynamically learned addresses are added to CAM until the maximum number is reached. Dynamically learned secure MAC addresses are lost when the switch reboots. _____________________________________________ Visit 21 Fill in the blank. Full-duplex communication allows both ends of a connection to transmit and receive data simultaneously. _______________________________ 22 Fill in the blank. When port security is enabled, a switch port uses the default violation mode of shutdown until specifically configured to use a different violation mode. ________________________________ 23 1a http://ccnav5.com 1b MATCHING Step 1.

  7. 7. 3 Visit http://ccnav5.com Refer to the exhibit. Based on the partial output from the show ip route command, what two facts can be determined about the RIP routing protocol? (Choose two.) RIP version 1 is running on this router and its RIP neighbor. RIP version 2 is running on this router and its RIP neighbor. The command no auto-summary has been used on the RIP neighbor router. RIP will advertise two networks to its neighbor. The metric to the network 172.16.0.0 is 120. 4 Which two statements describe the OSPF routing protocol? (Choose two.) automatically summarizes networks at the classful boundaries used primarily as an EGP uses Dijkstra's algorithm to build the SPF tree has an administrative distance of 100 Visit calculates its metric using bandwidth http://ccnav5.com 5 What is the purpose of the passive-interface command? allows a router to send routing updates on an interface but not receive updates via that innterface allows interfaces to share IP addresses allows a router to receive routing updates on an interface but not send updates via that interface allows an interface to remain up without receiving keepalives allows a routing protocol to forward updates out an interface that is missing its IP address 6 In the context of routing protocols, what is a definition for time to convergence? a measure of protocol configuration complexity the capability to transport data, video, and voice over the same media the amount of time for the routing tables to achieve a consistent state after a topology change the amount of time a network administrator needs to configure a routing protocol in a small- to medium-sized network 7 Which two events will trigger the sending of a link-state packet by a link-state routing protocol? (Choose two.) the requirement to periodically flood link-state packets to all neighbors a change in the topology Visit http://ccnav5.com
  8. 8. the initial startup of the routing protocol process the router update timer expiring a link to a neighbor router has become congested 8 Fill in the blank. Do not abbreviate the answer. The command version 2 is used in RIP router configuration mode to enable the sending of subnet masks with the routing updates. 9 What two actions result from entering the network 192.168.1.0 command in RIP configuration mode on a router? (Choose two.) The routing table is created in the RAM of the router. The RIP process is stopped and all existing RIP configurations are erased. The neighboring routers are sent a request for routing updates. Routing updates are sent through all the interfaces belonging to 192.168.1.0. The network address 192.168.1.0 is advertised to the neighbor routers. 10 What two tasks do dynamic routing protocols perform? (Choose two.) network discovery discover hosts propagate host default gateways assign IP addressing update and maintain routing tables Visit http://ccnav5.com 12 13 Refer to the exhibit. Which interface will be the exit interface to forward a data packet with the destination IP address 172.16.0.66?

  9. 9. 16 Fill in the blank. Do not abbreviate. When configuring RIPng, the default-information originate command instructs the router to propagate a static default route. 17 What is different between IPv6 routing table entries compared to IPv4 routing table entries? IPv6 does not use static routes to populate the routing table as used in IPv4. The selection of IPv6 routes is based on the shortest matching prefix, unlike IPv4 route selection which is based on the longest matching prefix. IPv6 routing tables include local route entries which IPv4 routing tables do not. By design IPv6 is classless so all routes are effectively level 1 ultimate routes. 18 Which two requirements are necessary before a router configured with a link-state routing protocol can build and send its link-state packets? (Choose two.) The router has constructed an SPF tree. Visit The router has built its link-state database. The router has established its adjacencies.

The routing table has been refreshed. http://ccnav5.com 19 Which dynamic routing protocol was developed as an exterior gateway protocol to interconnect different Internet providers? OSPF EIGRP RIP BGP 20 Which two requirements are used to determine if a route can be considered as an ultimate route in a router's routing table? (Choose two.) contain subnets contain a next-hop IP address Visit contain an exit interface be a default route be a classful network entry http://ccnav5.com 21 A destination route in the routing table is indicated with a code D. Which kind of route entry is this? a route dynamically learned through the EIGRP routing protocol a network directly connected to a router interface a route used as the default gateway a static route 22 Which route will a router use to forward an IPv4 packet after examining its routing table for the best match with the destination address? a level 1 ultimate route a level 2 supernet route
