Answer: B
Explanation:

In the diagram, DeepSouth is connected to Dubai’s S1/2 interface and is configured as follows:
Interface Serial1/2
IP address 192.168.0.5 255.255.255.252
Encapsulalation PPP ; Encapsulation for this interface is PPP
Check out the following Cisco Link:

Here is a snipit of an example:
Network Diagram
If Router 1 initiates a call to Router 2, Router 2 would challenge Router 1, but Router 1 would not challenge Router 2. This occurs because the ppp authentication chap callin command is configured on Router 1. This is an example of a unidirectional authentication. In this setup, the ppp chap hostname alias-r1 command is configured on Router 1. Router 1 uses “alias-r1” as its hostname for CHAP authentication instead of “r1.” The Router 2 dialer map name should match Router 1’s ppp chap hostname; otherwise, two B channels are established, one for each direction.

Explanation:
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).

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
Explanation:
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 172.16.2.64/26
172.16.2.228/30

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
Explanation:
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.

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?

A.    192.168.0.1
B.    172.16.1.1
C.    172.16.2.1
D.    172.16.2.225

Answer: A
Explanation:
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 192.168.0.1 is chosen as the router ID.

QUESTION 41
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:
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.

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
Explanation:
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 10.0.0.5 255.255.255.255 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.

QUESTION 45
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
Explanation:
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.

QUESTION 32
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: BD
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.

QUESTION 35
What is the result of issuing the frame-relay map ip 192.168.1.2 202 broadcast command?

A.    defines the destination IP address that is used in all broadcast packets on DCLI 202
B.    defines the source IP address that is used in all broadcast packets on DCLI 202
C.    defines the DLCI on which packets from the 192.168.1.2 IP address are received
D.    defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address

Answer: D
Explanation:
frame-relay map ip 192.168.1.2 202 command statically defines a mapping between a network layer address and a DLCI. The broadcast option allows multicast and broadcast packets to flow across the link.
The command frame-relay map ip 192.168.1.2 202 broadcast means to mapping the distal IP 192.168.1.2 202 to the local DLCI . When the “broadcast” keyword is included, it turns Frame Relay network as a broadcast network, which can forward broadcasts. http://www.cisco.com/en/US/docs/ios/wan/command/reference/wan_f2.html#wp1012264

QUESTION 36
Which Layer 2 protocol encapsulation type supports synchronous and asynchronous circuits and has built-in security mechanisms?

A.    HDLC
B.    PPP
C.    X.25
D.    Frame Relay

Answer: B
Explanation:
High-Level Data Link Control (HDLC) – HDLC is the default encapsulation type on point-to-point, dedicated links, and circuit-switched connections. It is used typically when communicating between two Cisco devices. It is a bit-oriented synchronous data link layer protocol.
Point-to-Point Protocol (PPP) – Provides router-to-router and host-to network connections over synchronous and asynchronous circuits. PPP was designed to work with several network layer protocols, such as IP, and IPX. PPP also has built in security mechanisms such as PAP and CHAP X.25/Link Access Procedure, Balanced (LAPB) – ITU-T standard that defines how connections between DTE and DCE are maintained for remote terminal access and computer communications in public data networks. X.25 specifies LAPB, a data line layer protocol. X.25 is a predecessor to Frame Relay.
Frame Relay – Industry standard, switched data link layer protocol that handles multiple virtual circuits. It is a next-generation to X.25 that is streamlined to eliminate some of the time-consuming processes (such as error correction and flow control) that were employed in X.25.

QUESTION 37
Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers?

A.    IETF
B.    ANSI Annex D
C.    Q9333-A Annex A
D.    HDLC

Answer: A
Explanation:
Cisco supports two Frame Relay encapsulation types: the Cisco encapsulation and the IETF Frame Relay encapsulation, which is in conformance with RFC 1490 and RFC 2427. The former is often used to connect two Cisco routers while the latter is used to connect a Cisco router to a non-Cisco router. You can test with your Cisco router when typing the command
Router(config-if)#encapsulation frame-relay ? on a WAN link.
Note: Three LMI options are supported by Cisco routers are ansi, Cisco, and Q933a. They represent the ANSI Annex D, Cisco, and ITU Q933-A (Annex A) LMI types, respectively.
HDLC is a WAN protocol same as Frame-Relay and PPP so it is not a Frame Relay encapsulation type.

QUESTION 38
The internetwork infrastructure of company XYZ consists of a single OSPF area as shown in the graphic. There is concern that a lack of router resources is impeding internetwork performance. As part of examining the router resources, the OSPF DRs need to be known. All the router OSPF priorities are at the default and the router IDs are shown with each router. Which routers are likely to have been elected as DR? (Choose two.)

A.    Corp-1
B.    Corp-2
C.    Corp-3
D.    Corp-4
E.    Branch-1
F.    Branch-2

Answer: DF
Explanation:
There are 2 segments on the topology above which are separated by Corp-3 router.
Each segment will have a DR so we have 2 DRs.
To select which router will become DR they will compare their router-IDs. The router with highest (best) router-ID will become DR. The router-ID is chosen in the order below:
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.
In this question, the IP addresses of loopback interfaces are not mentioned so we will consider IP addresses of all active router’s physical interfaces. Router Corp-4 (10.1.40.40) & Branch-2 (10.2.20.20) have highest “active” IP addresses so they will become DRs.

QUESTION 39
A network administrator needs to configure a serial link between the main office and a remote location. The router at the remote office is a non-Cisco router. How should the network administrator configure the serial interface of the main office router to make the connection?

A.    Main(config)# interface serial 0/0
Main(config-if)# ip address 172.16.1.1 255.255.255.252
Main(config-if)# no shut
B.    Main(config)# interface serial 0/0
Main(config-if)# ip address 172.16.1.1 255.255.255.252
Main(config-if)# encapsulation ppp
Main(config-if)# no shut
C.    Main(config)# interface serial 0/0
Main(config-if)# ip address 172.16.1.1 255.255.255.252
Main(config-if)# encapsulation frame-relay
Main(config-if)# authentication chap
Main(config-if)# no shut
D.    Main(config)# interface serial 0/0
Main(config-if)#ip address 172.16.1.1 255.255.255.252
Main(config-if)#encapsulation ietf
Main(config-if)# no shut

Answer: B
Explanation:
Cisco High-Level Data Link Controller (HDLC) is the Cisco proprietary protocol for sending data over synchronous serial links using HDLC. So HDLC runs only in Cisco router. PPP is not proprietary protocol it’s a open source every cisco router and non-cisco router understand the PPP protocol.So we need to configure the PPP protocol if connection is between cisco and non-cisco router.

QUESTION 40
Which PPP subprotocol negotiates authentication options?

A.    NCP
B.    ISDN
C.    SLIP
D.    LCP
E.    DLCI

Answer: D
Explanation:
A protocol that establishes, configures, and tests data link connections used by the PPP Link Control Protocol offers PPP encapsulation different options, including the following:
Authentication – options includes PAP and CHAP
Compression – Data compression increases the throughput on a network link, by reducing the amount of data that must be transmitted. Error Detection -Quality and Magic numbers are used by PPP to ensure a reliable, loop-free data link.
Multilink – Supported in IOS 11.1 and later, multilink is supported on PPP links between Cisco routers. This splits the load for PPP over two or more parallel circuits and is called a bundle.
