New Questions 1

Which of the following should be entered into the IP properties box for the sales server?
A. IP address: 192.168.20.14
Subnet Mask: 255.255.255.248
Default Gateway: 192.168.20.9
B. IP address: 192.168.20.254
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.20.1
C. IP address: 192.168.20.30
Subnet Mask: 255.255.255.248
Default Gateway: 192.168.20.25
D. IP address: 192.168.20.30
Subnet Mask: 255.255.255.240
Default Gateway: 192.168.20.17
E. IP address: 192.168.20.30
Subnet Mask: 255.255.255.240
Default Gateway: 192.168.20.25
Answer: C
Explanation:
For the 192.168.20.24/29 network, the usable hosts are 192.168.24.25 (router) u2013 192.168.24.30 (used for the sales server).
New Questions 2
Cisco Catalyst switches CAT1 and CAT2 have a connection between them using ports FA0/13. An 802.1Q trunk is configured between the two switches. On CAT1, VLAN 10 is chosen as native, but on CAT2 the native VLAN is not specified.
What will happen in this scenario?
A. 802.1Q giants frames could saturate the link.
B. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.
C. A native VLAN mismatch error message will appear.
D. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send tagged frames.
Answer: C
Explanation:
A u201cnative VLAN mismatchu201d error will appear by CDP if there is a native VLAN mismatch on an 802.1Q link. u201cVLAN mismatchu201d can cause traffic from one vlan to leak into another vlan.
New Questions 3
Which IEEE standard protocol is initiated as a result of successful DTP completion in a switch over Fast Ethernet?
A. 802.3ad
B. 802.1w
C. 802.1D
D. 802.1Q
Answer: D
Explanation:
Dynamic Trunking Protocol (DTP) is a Cisco proprietary protocol for negotiating trunking on a link between two devices and for negotiating the type of trunking encapsulation (802.1Q) to be used.
New Questions 4
The output of the show frame-relay pvc command shows "PVC STATUS = INACTIVE". What does this mean?
A. The PVC is configured correctly and is operating normally, but no data packets have been detected for more than five minutes.
B. The PVC is configured correctly, is operating normally, and is no longer actively seeking the address of the remote router.
C. The PVC is configured correctly, is operating normally, and is waiting for interesting traffic to trigger a call to the remote router.
D. The PVC is configured correctly on the local switch, but there is a problem on the remote end of the PVC.
E. The PVC is not configured on the local switch.
Answer: D
Explanation:
The PVC STATUS displays the status of the PVC. The DCE device creates and sends the report to the DTE devices. There are 4 statuses:
+ ACTIVE: the PVC is operational and can transmit data
+ INACTIVE: the connection from the local router to the switch is working, but the connection to the remote router is not available
+ DELETED: the PVC is not present and no LMI information is being received from the Frame Relay switch
+ STATIC: the Local Management Interface (LMI) mechanism on the interface is disabled (by using the u201cno keepaliveu201d command). This status is rarely seen so it is ignored in some books.
New Questions 5
Refer to the exhibit.
Why is flash memory erased prior to upgrading the IOS image from the TFTP server?
A. The router cannot verify that the Cisco IOS image currently in flash is valid.
B. Flash memory on Cisco routers can contain only a single IOS image.
C. Erasing current flash content is requested during the copy dialog.
D. In order for the router to use the new image as the default, it must be the only IOS image in flash.
Answer: C
Explanation:
During the copy process, the router asked u201cErasing flash before copying? [confirm]u201d and the administrator confirmed (by pressing Enter) so the flash was deleted.
Note: In this case, the flash has enough space to copy a new IOS without deleting the current one. The current IOS is deleted just because the administrator wants to do so. If the flash does not have enough space you will see an error message like this:
%Error copying tftp://192.168.2.167/ c1600-k8sy-mz.l23-16a.bin (Not enough space on device)
New Questions 6
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.

Refer to the exhibit.
The network administrator must establish a route by which London workstations can forward traffic to the Manchester workstations. What is the simplest way to accomplish this?
A. Configure a dynamic routing protocol on London to advertise all routes to Manchester.
B. Configure a dynamic routing protocol on London to advertise summarized routes to Manchester.
C. Configure a dynamic routing protocol on Manchester to advertise a default route to the London router.
D. Configure a static default route on London with a next hop of 10.1.1.1.
E. Configure a static route on London to direct all traffic destined for 172.16.0.0/22 to 10.1.1.2.
F. Configure Manchester to advertise a static default route to London.
Answer: E
Explanation:
This static route will allow for communication to the Manchester workstations and it is better to use this more specific route than a default route as traffic destined to the Internet will then not go out the London Internet connection.
New Questions 8
A network administrator enters the following command on a router: logging trap 3. What are three message types that will be sent to the Syslog server? (Choose three.)
A. informational
B. emergency
C. warning
D. critical
E. debug
F. error
Answer: B,D,F
Explanation:
The Message Logging is divided into 8 levels as listed below:
Level Keyword Description 0
emergencies System is unusable 1
alerts
Immediate action is needed 2
critical
Critical conditions exist 3
errors
Error conditions exist
4
warnings
Warning conditions exist 5
notification
Normal, but significant, conditions exist 6
informational Informational messages 7
debugging Debugging messages
If you specify a level with the u201cloggingtrap levelu201d command, that level and all the higher levels will be logged. For example, by using the u201clogging trap 3 command, all the logging of emergencies, alerts, critical, and errors, will be logged.
New Questions 9
Refer to the exhibit.
For what two reasons has the router loaded its IOS image from the location that is shown? (Choose two.)
A. Router1 has specific boot system commands that instruct it to load IOS from a TFTP server.
B. Router1 is acting as a TFTP server for other routers.
C. Router1 cannot locate a valid IOS image in flash memory.
D. Router1 defaulted to ROMMON mode and loaded the IOS image from a TFTP server.
E. Cisco routers will first attempt to load an image from TFTP for management purposes.
Answer: A,C
Explanation:
The loading sequence of CISCO IOS is as follows: Booting up the router and locating the Cisco IOS
1. POST (power on self-test)
2. Bootstrap code executed
3. Check Configuration Register value (NVRAM) which can be modified using the config- register command
0 = ROM Monitor mode 1 = ROM IOS
2 - 15 = startup-config in NVRAM
4. Startup-config filE. Check for boot system commands (NVRAM)
If boot system commands in startup-config
a. Run boot system commands in order they appear in startup-config to locate the IOS
b. [If boot system commands fail, use default fallback sequence to locate the IOS (Flash, TFTP, ROM)?]
If no boot system commands in startup-config use the default fallback sequence in locating the IOS:
a. Flash (sequential)
b. TFTP server (netboot)
c. ROM (partial IOS) or keep retrying TFTP depending upon router model
5. If IOS is loaded, but there is no startup-config file, the router will use the default fallback sequence for locating the IOS and then it will enter setup mode or the setup dialogue.
New Questions 10
Which statement describes the process ID that is used to run OSPF on a router?
A. It is globally significant and is used to represent the AS number.
B. It is locally significant and is used to identify an instance of the OSPF database.
C. It is globally significant and is used to identify OSPF stub areas.
D. It is locally significant and must be the same throughout an area.
Answer: B
Explanation:
The Process ID for OSPF on a router is only locally significant and you can use the same number on each router, or each router can have a different number-it just doesn't matter. The numbers you can use are from 1 to 65,535. Don't get this confused with area numbers, which can be from 0 to 4.2 billion.
