QUESTION 61
What is the default administrative distance of OSPF?

A.    90
B.    100
C.    110
D.    120

Answer: C
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.

QUESTION 62
Which characteristics are representative of a link-state routing protocol? (Choose three.)

A.    provides common view of entire topology
B.    exchanges routing tables with neighbors
C.    calculates shortest path
D.    utilizes event-triggered updates
E.    utilizes frequent periodic updates

Answer: ACD
Explanation:
Each of routers running link-state routing protocol learns paths to all the destinations in its “area” so we can say although it is a bit unclear.
Link-state routing protocols generate routing updates only (not the whole routing table) when a change occurs in the network topology so
Link-state routing protocol like OSPF uses Dijkstra algorithm to calculate the shortest path -> . Unlike Distance vector routing protocol (which utilizes frequent periodic updates), link-state routing protocol utilizes event-triggered updates (only sends update when a change occurs) ->

QUESTION 63
Which command would you configure globally on a Cisco router that would allow you to view directly connected Cisco devices?

A.    enable cdp
B.    cdp enable
C.    cdp run
D.    run cdp

Answer: C
Explanation:
CDP is enabled on Cisco routers by default. If you prefer not to use the CDP capability, disable it with the no cdp run command. In order to reenable CDP, use the cdp run command in global configuration mode. The “cdp enable” command is an interface command, not global.

QUESTION 64
Which two locations can be configured as a source for the IOS image in the boot system command? (Choose two.)

A.    RAM
B.    NVRAM
C.    flash memory
D.    HTTP server
E.    TFTP server
F.    Telnet server

Answer: CE
Explanation:
The following locations can be configured as a source for the IOS image:
1. + Flash (the default location)
2. + TFTP server
3. + ROM (used if no other source is found)

QUESTION 65
Which two statements describe the process identifier that is used in the command to configure OSPF on a router? (Choose two.)
Router(config)# router ospf 1

A.    All OSPF routers in an area must have the same process ID
B.    Only one process number can be used on the same router.
C.    Different process identifiers can be used to run multiple OSPF processes
D.    The process number can be any number from 1 to 65,535.
E.    Hello packets are sent to each neighbor to determine the processor identifier.

Answer: CD
Explanation:
Multiple OSPF processes can be configured on a router using multiple process ID’s.
The valid process ID’s are shown below:
Edge-B(config)#router ospf ?
<1-65535> Process ID

QUESTION 66
Which three elements must be used when you configure a router interface for VLAN trunking? (Choose three.)

A.    one physical interface for each subinterface
B.    one IP network or subnetwork for each subinterface
C.    a management domain for each subinterface
D.    subinterface encapsulation identifiers that match VLAN tags
E.    one subinterface per VLAN
F.    subinterface numbering that matches VLAN tags

Answer: BDE
Explanation:
This scenario is commonly called a router on a stick. A short, well written article on this operation can be found here:

QUESTION 67
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: BE
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 “network” statement, not a subnet mask. We also need to assgin an area to this process -> .

QUESTION 68
A router receives information about network 192.168.10.0/24 from multiple sources. What will the router consider the most reliable information about the path to that network?

A.    a directly connected interface with an address of 192.168.10.254/24
B.    a static route to network 192.168.10.0/24
C.    a RIP update for network 192.168.10.0/24
D.    an OSPF update for network 192.168.0.0/16
E.    a default route with a next hop address of 192.168.10.1
F.    a static route to network 192.168.10.0/24 with a local serial interface configured as the next hop

Answer: A
Explanation:
When there is more than one way to reach a destination, it will choose the best one based on a couple of things. First, it will choose the route that has the longest match; meaning the most specific route. So, in this case the /24 routes will be chosen over the /16 routes. Next, from all the /24 routes it will choose the one with the lowest administrative distance. Directly connected routes have an AD of 1 so this will be the route chosen.

QUESTION 69
What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?

A.    2
B.    4
C.    16
D.    unlimited

Answer: B
Explanation:
maximum-paths (OSPF)
To control the maximum number of parallel routes that Open Shortest Path First (OSPF) can support, use the maximum-paths command.
Syntax Description
maximum
Maximum number of parallel routes that OSPF can install in a routing table. The range is from 1 to 16 routes.
Command Default
8 paths

QUESTION 70
Which command shows your active Telnet connections?

A.    show cdp neigbors
B.    show session
C.    show users
D.    show vty logins

Answer: B
Explanation:
The “show users” shows telnet/ssh connections to your router while “show sessions” shows telnet/ssh connections from your router (to other devices). The question asks about “your active Telnet connections”, meaning connections from your router so the answer should be A.
