New Cisco 200-105 Exam Dumps Collection (Question 13 - Question 22)

New Questions 13

Refer to the exhibit

Which switch provides the spanning-tree designated port role for the network segment that services the printers?

A. Switch1

B. Switch2

C. Switch3

D. Switch4

Answer: C

Explanation:

First, the question asks what switch services the printers, so it can be Switch 3 or Switch 4 which is connected directly to the Printers.

Designated port is a port that is in the forwarding state. All ports of the root bridge are designated ports.

Switch 3 and Switch 4 has same priority so it will see on lowest MAC address and here switch 3 has lowest MAC address. So switch 3 segment will play a Designated port role. By comparing the MAC address of Switch 3 and Switch 4 we found that the MAC of Switch 3 is smaller. Therefore the interface connected to the Printers of Switch 3 will become designated interface and the interface of Switch 4 will be blocked.

New Questions 15

Which Cisco platform can verify ACLs?

A. Cisco Prime Infrastructure

B. Cisco Wireless LAN Controller

C. Cisco APIC-EM

D. Cisco IOS-XE

Answer: C


New Questions 16

Refer to the exhibit.

What is the meaning of the term dynamic as displayed in the output of the show frame- relay map command shown?

A. The Serial0/0 interface is passing traffic.

B. The DLCI 100 was dynamically allocated by the router

C. The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server

D. The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud

E. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP

Answer: E

Explanation:

The term dynamic indicates that the DLCI number and the remote router IP address

172.16.3.1 are learned via the Inverse ARP process.

Inverse ARP is a technique by which dynamic mappings are constructed in a network, allowing a device such as a router to locate the logical network address and associate it with a permanent virtual circuit (PVC).


New Questions 17

Refer to the exhibit.

What commands must be configured on the 2950 switch and the router to allow communication between host 1 and host 2? (Choose two.)

A. Router(config)# interface fastethernet 0/0 Router(config-if)# ip address 192.168.1.1 255.255.255.0 Router(config-if)# no shut down

B. Router(config)# interface fastethernet 0/0 Router(config-if)# no shut down Router(config)# interface fastethernet 0/0.1 Router(config-subif)# encapsulation dot1q 10

Router(config-subif)# ip address 192.168.10.1 255.255.255.0 Router(config)# interface fastethernet 0/0.2

Router(config-subif)# encapsulation dot1q 20

Router(config-subif)# ip address 192.168.20.1 255.255.255.0

C. Router(config)# router eigrp 100 Router(config-router)# network 192.168.10.0

Router(config-router)# network 192.168.20.0

D. Switch1(config)# vlan database Switch1(config-vlan)# vtp domain XYZ Switch1(config-vlan)# vtp server

E. Switch1(config)# interface fastethernet 0/1 Switch1(config-if)# switchport mode trunk

F. Switch1(config)# interface vlan 1 Switch1(config-if)# ip default-gateway 192.168.1.1

Answer: B,E

Explanation:

The two answers B and E list all the commands needed to configure interVLAN routing. Please notice that Cisco switch 2950, 2960 only support dot1Q trunking so we donu2021t need to specify which trunking encapsulation to use in this case. For Cisco switches 3550 or above we have to use these commands instead:

Switch3550(config-if)#switchport trunk encapsulation dot1q Switch3550(config-if)#switchport mode trunk

New Questions 18

Which two are advantages of static routing when compared to dynamic routing? (Choose two.)

A. Configuration complexity decreases as network size increases.

B. Security increases because only the network administrator may change the routing table.

C. Route summarization is computed automatically by the router.

D. Routing tables adapt automatically to topology changes.

E. An efficient algorithm is used to build routing tables, using automatic updates.

F. Routing updates are automatically sent to neighbors.

G. Routing traffic load is reduced when used in stub network links.

Answer: B,G

Explanation:

When reading (or being lectured about) all the glorious details of dynamic routing protocols, it's hard not to come away with the impression that dynamic routing is always better than static routing. It's important to keep in mind that the primary duty of a dynamic routing protocol is to automatically detect and adapt to topological changes in the internetwork. The price of this "automation" is paid in bandwidth, security, and maybe queue space, in memory, and in processing time.

A frequent objection to static routing is that it is hard to administer. This criticism may be true of medium to large topologies with many alternative routes, but it is certainly not true of small internetworks with few or no alternative routes.

New Questions 19

Which two components are used to identify a neighbor in a BGP configuration? (Choose two.)

A. autonomous system number

B. version number

C. router ID

D. subnet mask

E. IP address

Answer: A,E

Explanation:

Use the show ip bgp neighbors (registered customers only) command to display information about the TCP and Border Gateway Protocol (BGP) connections and verify if the BGP peer is established. The output of the show ip bgp neighbors command below shows the BGP state as 'Established', which indicates that the BGP peer relationship has been established successfully.

R1-AGS# show ip bgp neighbors | include BGP

BGP neighbor is 10.10.10.2, remote AS 400, internal link

BGP version 4, remote router ID 2.2.2.2 BGP state = Established, up for 00:04:20 BGP table version 1, neighbor version 1 R1-AGS#

The show ip bgp neighbors command has been used above with the modifier | include BGP. This makes the output more readable by filtering the the command output and displaying the relevant parts only.

In addition, the show ip bgp summary (registered customers only) command can also be used to display the status of all BGP connections, as shown below.

R1-AGS(9)# show ip bgp summary

BGP router identifier 10.1.1.2, local AS number 400 BGP table version is 1, main routing table version 1

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd 10.10.10.2 4 400 3 3 1 0 0 00:00:26 0


New Questions 20

What can be done to Frame Relay to resolve split-horizon issues?(Choose two.)

A. Disable Inverse ARP.

B. Create a full-mesh topology.

C. Develop multipoint subinterfaces.

D. Configure point-to-point subinterfaces.

E. Remove the broadcast keyword from the frame-relay map command.

Answer: B,D

Explanation:

IP split horizon checking is disabled by default for Frame Relay encapsulation to allow routing updates to go in and out of the same interface. An exception is the Enhanced Interior Gateway Routing Protocol (EIGRP) for which split horizon must be explicitly disabled.

Certain protocols such as AppleTalk, transparent bridging, and Internetwork Packet Exchange (IPX) cannot be supported on partially meshed networks because they require split horizon to be enabled (a packet received on an interface cannot be transmitted over the same interface, even if the packet is received and transmitted on different virtual circuits).

Configuring Frame Relay subinterfaces ensures that a single physical interface is treated as multiple virtual interfaces. This capability allows you to overcome split horizon rules so packets received on one virtual interface can be forwarded to another virtual interface, even if they are configured on the same physical interface.


New Questions 21

Refer to the exhibit.

A technician has configured the FastEthernet 0/1 interface on Sw11 as an access link in VLAN 1. Based on the output from the show vlan brief command issued on Sw12, what will be the result of making this change on Sw11?

A. Only the hosts in VLAN 1 on the two switches will be able to communicate with each other.

B. The hosts in all VLANs on the two switches will be able to communicate with each other.

C. Only the hosts in VLAN 10 and VLAN 15 on the two switches will be able to communicate with each other.

D. Hosts will not be able to communicate between the two switches.

Answer: D

Explanation:

VLANs are local to each switch's database, and VLAN information is not passed between switches without implementing VLAN Trunk Protocol (VTP). Trunks carry traffic from all VLANs to and from the switch by default but, can be configured to carry only specified VLAN traffic. Trunk links are required to pass VLAN information between switches. So Sw11 port should be trunk not access port. Additionally, there are no ports assigned to VLAN 1.


New Questions 22

Refer to the exhibit.

Given the output for this command, if the router ID has not been manually set, what router ID will OSPF use for this router?

A. 10.1.1.2

B. 10.154.154.1

C. 172.16.5.1

D. 192.168.5.3

Answer: C

Explanation:

CCNA Tutorial: The OSPF Router ID (RID) http://www.thebryantadvantage.com/CCNACertificationExamTutorialOSPFRouterIDRID.ht m

When determining the Router ID (RID) of an OSPF-enabled router, OSPF will always use the numerically highest IP address on the routeru2021s loopback interfaces, regardless of whether that loopback is OSPF-enabled.

What if there is no loopback? OSPF will then use the numerically highest IP address of the physical interfaces, regardless of whether that interface is OSPF-enabled.
