New Cisco 200-125 Exam Dumps Collection (Question 13 - Question 22)
New Questions 13
Which command reveals the last method used to powercycle a router?
A. show reload
B. show boot
C. show running-config
D. show version
Answer: D
Explanation:
The u201cshow versionu201d command can be used to show the last method to powercycle (reset) a router.
New Questions 14
Why do large OSPF networks use a hierarchical design? (Choose three.)
A. to decrease latency by increasing bandwidth
B. to reduce routing overhead
C. to speed up convergence
D. to confine network instability to single areas of the network
E. to reduce the complexity of router configuration
F. to lower costs by replacing routers with distribution layer switches
Answer: B,C,D
Explanation:
OSPF implements a two-tier hierarchical routing model that uses a core or backbone tier known as area zero (0). Attached to that backbone via area border routers (ABRs) are a number of secondary tier areas. The hierarchical approach is used to achieve the following:
u2022Rapid convergence because of link and/or switch failures
u2022Deterministic traffic recovery
u2022Scalable and manageable routing hierarchy, reduced routing overhead.
New Questions 15
Refer to the exhibit.
In this VLSM addressing scheme, what summary address would be sent from router A?
A. 172.16.0.0 /16
B. 172.16.0.0 /20
C. 172.16.0.0 /24
D. 172.32.0.0 /16
E. 172.32.0.0 /17
F. 172.64.0.0 /16
Answer: A
Explanation:
Router A receives 3 subnets: 172.16.64.0/18, 172.16.32.0/24 and 172.16.128.0/18.
All these 3 subnets have the same form of 172.16.x.x so our summarized subnet must be also in that form -> Only A, B or .
The smallest subnet mask of these 3 subnets is /18 so our summarized subnet must also have its subnet mask equal or smaller than /18.
-> Only answer A has these 2 conditions ->.
New Questions 16
A Cisco router is booting and has just completed the POST process. It is now ready to find and load an IOS image. What function does the router perform next?
A. It checks the configuration register.
B. It attempts to boot from a TFTP server.
C. It loads the first image file in flash memory.
D. It inspects the configuration file in NVRAM for boot instructions.
Answer: A
Explanation:
Default (normal) Boot Sequence
Power on Router - Router does POST - Bootstrap starts IOS load - Check configuration register to see what mode the router should boot up in (usually 0x2102 to read startup- config in NVRAM / or 0x2142 to start in "setup-mode") - check the startup-config file in NVRAM for boot-system commands - load IOS from Flash.
New Questions 17
Which commands are required to properly configure a router to run OSPF and to add network 192.168.16.0/24 to OSPF area 0? (Choose two.)
A. Router(config)# router ospf 0
B. Router(config)# router ospf 1
C. Router(config)# router ospf area 0
D. Router(config-router)# network 192.168.16.0 0.0.0.255 0
E. Router(config-router)# network 192.168.16.0 0.0.0.255 area 0
F. Router(config-router)# network 192.168.16.0 255.255.255.0 area 0
Answer: B,E
Explanation:
In the router ospf command, the ranges from 1 to 65535 so o is an invalid number -> but To configure OSPF, we need a wildcard in the u201cnetworku201d statement, not a subnet mask. We also need to assgin an area to this process ->.
New Questions 18
Refer to the exhibit.
Which of these statements correctly describes the state of the switch once the boot process has been completed?
A. As FastEthernet0/12 will be the last to come up, it will be blocked by STP.
B. Remote access management of this switch will not be possible without configuration change.
C. More VLANs will need to be created for this switch.
D. The switch will need a different IOS code in order to support VLANs and STP.
Answer: B
Explanation:
Notice the line, which says u201cInterface VLAN1, changed state to administratively downu201d. This shows that VLAN1 is shut down. Hence remote management of this switch is not possible unless VLAN1 is brought back up. Since VLAN1 is the only interface shown in the output, you have to assume that no other VLAN interface has been configured with an IP Address.
New Questions 19
A router has two Fast Ethernet interfaces and needs to connect to four VLANs in the local network. How can you accomplish this task, using the fewest physical interfaces and without decreasing network performance?
A. Use a hub to connect the four VLANS with a Fast Ethernet interface on the router.
B. Add a second router to handle the VLAN traffic.
C. Add two more Fast Ethernet interfaces.
D. Implement a router-on-a-stick configuration.
Answer: D
Explanation:
A router on a stick allows you to use sub-interfaces to create multiple logical networks on a single physical interface.
New Questions 20
Refer to the exhibit.
What is the effect of the configuration that is shown?
A. It configures SSH globally for all logins.
B. It tells the router or switch to try to establish an SSh connection first and if that fails to use Telnet.
C. It configures the virtual terminal lines with the password 030752180500.
D. It configures a Cisco network device to use the SSH protocol on incoming communications via the virtual terminal ports.
E. It allows seven failed login attempts before the VTY lines are temporarily shutdown.
Answer: D
Explanation:
Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. Communication between the client and server is encrypted in both SSH version 1 and SSH version 2. If you want to prevent non-SSH connections, add the
u201ctransport input sshu201d command under the lines to limit the router to SSH connections only. Straight (non-SSH) Telnets are refused.

New Questions 21
Refer to the exhibit.
Given the output shown from this Cisco Catalyst 2950, what is the reason that interface FastEthernet 0/10 is not the root port for VLAN 2?
A. This switch has more than one interface connected to the root network segment in VLAN 2.
B. This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree.
C. This switch interface has a higher path cost to the root bridge than another in the topology.
D. This switch has a lower bridge ID for VLAN 2 than the elected designated switch.
Answer: C
Explanation:
Since the port is in the blocked status, we must assume that there is a shorter path to the root bridge elsewhere.
New Questions 22
What parameter can be different on ports within an EtherChannel?
A. speed
B. DTP negotiation settings
C. trunk encapsulation
D. duplex
Answer: B
Explanation:
For an etherchannel to come up, the speed, duplex and the trunk encapsulation must be the same on each end.
