Which commands are required to properly configure a router to run OSPF and to add network 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 0
E.    Router(config-router)# network area 0
F.    Router(config-router)# network area 0

Answer: BE
In the router ospf
command, theranges from 1 to 65535 so o is an invalid number – B is correct but A is not correct. 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 – E is correct.

Which type of EIGRP route entry describes a feasible successor?

A.    a backup route, stored in the routing table
B.    a primary route, stored in the routing table
C.    a backup route, stored in the topology table
D.    a primary route, stored in the topology table

Answer: C
Feasible successor is a route whose Advertised Distance is less than the Feasible Distance of the current best path. A feasible successor is a backup route, which is not stored in the routing table but stored in the topology table.

Drag and Drop Question
Drag each description on the left to the appropriate term on the right. Not all the descriptions are used.





Drag and Drop Question
Drag the term on the left to its definition on the right (Not all options are used.)




Poison reverse: A router learns from its neighbor that a route is down and the router sends an update back to the neighbor with an infinite metric to that routeLSA: The packets flooded when a topology change occurs, causing network routers to update their topological databases and recalculate routes
Split horizon: This prevents sending information about a routeback out the same interface that originally learned about the route holddown timer: For a given period, this causes the router to ignore any updates with poorer metrics to a lost network

Drag and Drop Question
Drat the description on the left to the routing protocol on the right. (Not all options are used.)




Drag and Drop Question
Drat the Frame Relay acronym on the left to match its definition on the right. (Not all acronyms are used)




Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco proprietary routing protocol, so it is vendor-specific. By default, EIGRP internal routes have an administrative distance value of 90. OSPF uses cost as its metric. By default, the cost of an interface is calculated based on bandwidth with the formula cost= 10000 0000/bandwidth (in bps). OSPF elects a DR on each broadcast and nonbroadcast multiaccess networks (like Ethernet and Frame Relay environments, respectively). It doesn’t elect a DR on point-to-point link (like a serial WAN).

Hotspot Question


OSPF is configured using default classful addressing. With all routers and interfaces operational, how many networks will be in the routing table of R1 that are indicated to be learned by OSPF?

A.    2
B.    3
C.    4
D.    5
E.    6
F.    7

Answer: C
It already knows about its directly connected ones, only those not directly connected
are “Learned by OSPF”.
OSPF as a link state routing protocol (deals with LSAs rather than routes) does not auto summarize (doesn’t support “auto-summary”).So learned route by OSPF are followed

Hotspot Question



After the network has converged, what type of messaging, if any, occurs between R3 and R4?

A.    No messages are exchanged.
B.    Hellos are sent every 10 seconds.
C.    The full database from each router is sent every 30 seconds.
D.    The routing table from each router is sent every 60 seconds.

Answer: B
HELLO messages are used to maintain adjacent neighbors so even when the network is converged, hellos are still exchanged. On broadcast and point-to-point links, the default is 10 seconds, on NBMA the default is 30 seconds.

Hotspot Question



To allow or prevent load balancing to network, which of the following commands could be used in R2? (Choose two.)

A.    R2(config-if)#clock rate
B.    R2(config-if)#bandwidth
C.    R2(config-if)#ip ospf cost
D.    R2(config-if)#ip ospf priority
E.    R2(config-router)#distance ospf

Answer: BC

Hotspot Question



R1 is configured with the default configuration of OSPF. From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID?


Answer: A
The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence:
+ The highest IP address assigned to a loopback (logical) interface. + If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen.
+ The router ID can be manually assigned
In this case, because a loopback interface is not configured so the highest active IP address is chosen as the router ID.

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
we all know that The areas can be any number from 0 to 4.2 billion and 1 to 65,535 for the Process ID.
The process ID is the ID of the OSPF process to which the interface belongs. The process ID is local to the router, and two OSPF neighboring routers can have different OSPF process IDs. (This is not true of Enhanced Interior Gateway Routing Protocol [EIGRP], in which the routers need to be in the same autonomous system). Cisco IOS Software can run multiple OSPF processes on the same router, and the process ID merely distinguishes one process from the another. The process ID should be a positive integer.

Refer to the exhibit. Given the output from the show ip eigrp topology command, which router is the feasible successor?


A.     clip_image001[13]
B.     clip_image001[15]
C.     clip_image001[17]
D.     clip_image001[19]

Answer: B

Which three of these statements regarding 802.1Q trunking are correct? (Choose three.)

A.    802.1Q native VLAN frames are untagged by default.
B.    802.1Q trunking ports can also be secure ports.
C.    802.1Q trunks can use 10 Mb/s Ethernet interfaces.
D.    802.1Q trunks require full-duplex, point-to-point connectivity.
E.    802.1Q trunks should have native VLANs that are the same at both ends.

Answer: ACE
To be the feasible successor, the Advertised Distance (AD) of that route must be less than the Feasible Distance (FD) of the successor. From the output of the “show ip eigrp topology we learn that the FD of the successor is 41152000. Now we will mention about the answers, in the “Composite metric is (…/…)” statement the first parameter is the FD while the second parameter is the AD of that route. So we need to find out which route has the second parameter (AD) less than 41152000 -> only answer B satisfies this requirement with an AD of 128256.

Which two options are valid WAN connectivity methods? (Choose two.)

A.    PPP
B.    WAP
C.    DSL
D.    L2TPv3
E.    Ethernet

Answer: AC
On each WAN connection, data is encapsulated into frames before itcrosses the WAN link. The following are typical WAN protocols:1. High-level Data Link Control (HDLC): The Cisco default encapsulation type onpoint-to-point connections, dedicated links, and circuit- switches connections.2. PPP: Provides router-to-router and host-to-network connections over synchronous andasynchronous circuits. PPP was designed to work with several network layer protocols,including IP.3. Frame-relay: A successor to X.25. This protocol is an industry-standard, switchesdata-link layer protocol that handles multiple virtual circuits

What occurs on a Frame Relay network when the CIR is exceeded?

A.    All TCP traffic is marked discard eligible.
B.    All UDP traffic is marked discard eligible and a BECN is sent.
C.    All TCP traffic is marked discard eligible and a BECN is sent.
D.    All traffic exceeding the CIR is marked discard eligible.

Answer: D
Committed information rate (CIR): The minimum guaranteed data transfer rate agreed to by the Frame Relay switch. Frames that are sent in excess of the CIR are marked as discard eligible (DE) which means they can be dropped if the congestion occurs within the Frame Relay network.
Note: In the Frame Relay frame format, there is a bit called Discard eligible (DE) bit that is used to identify frames that are first to be dropped when the CIR is exceeded.

What are two characteristics of Frame Relay point-to-point subinterfaces? (Choose two.)

A.    They create split-horizon issues.
B.    They require a unique subnet within a routing domain.
C.    They emulate leased lines.
D.    They are ideal for full-mesh topologies.
E.    They require the use of NBMA options when using OSPF.

Answer: BC

Which two statements about using the CHAP authentication mechanism in a PPP link are true? (Choose two.)

A.    CHAP uses a two-way handshake.
B.    CHAP uses a three-way handshake.
C.    CHAP authentication periodically occurs after link establishment.
D.    CHAP authentication passwords are sent in plaintext.
E.    CHAP authentication is performed only upon link establishment.
F.    CHAP has no protection from playback attacks.

Answer: BC

Which command allows you to verify the encapsulation type (CISCO or IETF) for a Frame Relay link?

A.    show frame-relay lmi
B.    show frame-relay map
C.    show frame-relay pvc
D.    show interfaces serial

Answer: B
map will show frame relay encapsulation (cisco or ietf)

What is the purpose of Inverse ARP?

A.    to map a known IP address to a MAC address
B.    to map a known DLCI to a MAC address
C.    to map a known MAC address to an IP address
D.    to map a known DLCI to an IP address
E.    to map a known IP address to a SPID
F.    to map a known SPID to a MAC address

Answer: D
Frame-Relay (a Layer 2 protocol) uses Inverse-Arp to map a know Layer 2 Address (DLCI) to a unknow Layer 3 Address.

What information does a router running a link-state protocol use to build and maintain its topological database? (Choose two.)

A.    hello packets
B.    SAP messages sent by other routers
C.    LSAs from other routers
D.    beacons received on point-to-point links
E.    routing tables received from other link-state routers
F.    TTL packets from designated routers

Answer: AC
