QUESTION NO:23

Refer to the exhibit. Your customer has enabled IPv6 and IPv4 on routers R1 and R2, both

running ISIS routing protocol, and they can no longer reach R3 network 172.26.15.0/24 (R3

does not enable IPv6, enables IPv4 only). Which two steps should be taken to restore

reach ability to R3? (Choose two.)

A. Enable OSPFv3 to support IPv4 and IPv6 simultaneously.

B. Configure static routes to all unreachable networks and redistribute to IS-IS.

C. Create an IPv6 tunnel from R2 to R3.

D. Transition to IS-IS Multiple Topology Mode on R3.

E. Enable wide metrics.

F. Transition to IS-IS Multiple Topology Mode on R1 and R2.

Answer: E,F

QUESTION NO:1

Which three modes are the operating of HDLC? (Choose three)

A. asynchronous balanced mode (ABM)

B. normal response mode (NRM)

C. normal peer mode (NPM)

D. asynchronous client mode (ACM)

E. asynchronous response mode (ARM)

Answer: A,B,E

Explanation:

Normal response mode allows operation over half-duplex communication links, as long as

the primary is aware that it may not transmit when it has given permission to a secondary.

Asynchronous response mode is an HDLC addition[1] for use over full-duplex links. While

retaining the primary/secondary distinction, it allows the secondary to transmit at any time.

Asynchronous balanced mode added the concept of a combined terminal which can act as

both a primary and a secondary. There are some subtleties about this mode of operation;

while many features of the protocol do not care whether they are in a command or

response frame, some do, and the address field of a received frame must be examined to

determine whether it contains a command (the address received is ours) or a response (the

address received is that of the other terminal).

QUESTION NO:24

What ISIS TLVs are used to support MPLS Traffic Engineering? (Choose three).

A. Extended IS neighbor TLV #22

B. Extended IS name TLV #137

C. Extended IS resource TLV #138

D. Extended IS reachability TLV #135

E. Router ID TLV #134

Answer: A,D,E

Explanation:

TLV Name Description

1 Area Address Includes the Area Addresses to which the Intermediate System is

connected.

2 IIS Neighbors Includes all the IS-ISs running interfaces to which the router is connected.

8 Padding Primarily used in the IS-IS Hello (IIH) packets to detect the maximum

transmission unit (MTU) inconsistencies. By default, IIH packets are padded to the fullest

MTU of the interface.

10 Authentication The information that is used to authenticate the PDU, 22 TE IIS

Neighbors Increases the maximum metric to three bytes (24 bits). Known as the Extended

IS

Reachability TLV, this TLV addresses a TLV 2 metric limitation. TLV 2 has a maximum

metric of 63, but only six out of eight bits are used.

128 IP Int. Reachability Provides all the known IP addresses that the given router knows

about via one or more internally-originated interfaces. This information may appear multiple

times.

129 Protocols Supported Carries the Network Layer Protocol Identifiers (NLPID) for

Network Layer protocols that the IS (Intermediate System) is capable. It refers to the Data

Protocols that are supported. For example, IPv4 NLPID value 0xCC, CLNS NLPID value

0x81, and/or IPv6 NLPID value 0x8E will be advertised in this NLPID TLV.

130 IP Ext. Address Provides all the known IP addresses that the given router knows about

via one or more externally-originated interfaces. This information may appear multiple

times.

132 IP Int. Address The IP interface address that is used to reach the next-hop address.

134 TE Router ID This is the Multi-Protocol Label Switching (MPLS) traffic engineering

router ID.

135 TE IP Reachability Provides a 32 bit metric and adds a bit for the “up/down” resulting

from the routeleaking of L2->L1. Known as the Extended IP Reachability TLV, this TLV

addresses the issues with both TLV 128 and TLV 130.

137 Dynamic Hostname Identifies the symbolic name of the router originating the link-state

packet (LSP).

10 and 133 TLV 10 should be used for Authentication; not the TLV 133. If TLV 133 is

received, it is ignored on receipt, like any other unknown TLVs. TLV 10 should be accepted

for authentication only.

QUESTION NO:18

Which of the following processes in IOS XR run exclusively on the Route Processor?

(Choose two.)

A. wdsysmon

B. mpls_idp

C. sysmgr

D. gsp

E. bgp

Answer: B,E

QUESTION NO:4

What is one of the primary overhead fields associated with the Optical Payload Unit

(OPU)?

A. path monitoring

B. tandem connection monitoring activation deactivation (TCM ACT)

C. Payload Structure Identifier (PSI)

D. multiframe alignment signal (MFAS)

E. section monitoring

Answer: C

Explanation:

Optical Payload Unit (OPU)

In order to begin describing the OTN as defined by the ITU G.709 standard, we must first

enumerate its critical elements, their termination points, and the way they relate to one

another in terms of hierarchy and function.

The primary overhead field associated with the OPU is the payload structure identifier

(PSI). This is a 256-byte multiframe whose first byte is defined as the payload type (PT).

The remaining 255 bytes are currently reserved. The other fields in the OPU overhead are

dependent on the mapping capabilities associated to the OPU. For an asynchronous

mapping (the client signal and OPU clock are different) justification control (JC) bytes are

available to Application Note 153Telecom Test and Measurement compensate for clock

rate differences. For a purely synchronous mapping (client source and OPU clock are the

same), the JC bytes become reserved. Further details on mapping are available in ITU

G.709.

QUESTION NO:15

When will the primary processor core dump run in case of a switchover?

A. never takes place

B. periodically

C. during switchover

D. after switchover

E. before switchover

Answer: D

Explanation:

In networking devices with redundant processors, the Post-Switchover Core Dump feature

uses better software communication techniques between redundant processors to allow

the switchover to occur before dumping core information. Not having to wait for dump

operations effectively decreases the switchover time between processors. The newly active

primary processor runs the core dump operation after switchover Reference:

QUESTION NO:30

What is the importance of using Virtual Output Queues on ingress Line Cards in a high-end

router?

A. Increases forwarding performance

B. Simplifies configuration

C. Prevents head-of-line blocking

D. Uses less memory

Answer: C

QUESTION NO:31

What is the default SPF throttle timer in OSPF?

A. 5s

B. 10ms

C. 0ms

D. 30s

E. 1s

F. 500ms

Answer: A

QUESTION NO:8

Which statement about Software Maintenance Upgrade is true?

A. CRS-1 SMU can be applied to a different platform, and vice versa.

B. SMU is an executable code for running a process or libraries that are shared between

the different processes.

C. SMUs for each release are individually downloadable from Cisco.com and come in the

form of a tar ball.

D. SMUs provide software fixes for critical network down and qualification blocking issues.

Therefore, every software defect has a corresponding SMU.

E. SMUs are release-specific. If an issue affects multiple platforms or releases, an SMU is

built separately for each release and each platform.

Answer: E

Explanation: 1.4. SP high end product

SMUs for each release are individually downloadable from Cisco.com, whereas the

bootable files and optional PIEs come in the form of a tarball.

SMUs are release specific. If an issue affects multiple platforms or releases, an SMU will

be separately built for each release and each platform depending on the mission-critical

need.

A CRS-1 SMU cannot be applied to a different platform, and vice versa.

SMUs provide software fixes for critical network-down and qualification-blocking issues.

Therefore, every software defect will not have a corresponding SMU.

QUESTION NO:28

Which two statements regarding the IS-IS DIS election process are true? (Choose two.)

A. L1 routers on a broadcast network only establish adjacencies with the DIS.

B. If the DIS becomes unavailable the backup DIS is promoted to DIS.

C. Adding a router with a higher priority than the current DIS will result in the new router

becoming DIS.

D. Separate L1 and L2 election processes are held on a brodcast network.

E. A priority of 0 will prevent a router from becoming a DIS.

F. If there is a tie based on priority, the router whose attached interface has the lowest

MAC address becomes the DIS.

Answer: C,D

Explanation:

Election of the DIS

On a LAN, one of the routers elects itself the DIS, based on interface priority (the default is

64). If all interface priorities are the same, the router with the highest subnetwork point of

attachment (SNPA) is selected. The SNPA is the MAC address on a LAN, and the local

data link connection identifier (DLCI) on a Frame Relay network. If the SNPA is a DLCI and

is the same at both sides of a link, the router with the higher system ID becomes the DIS.

Every IS-IS router interface is assigned both a L1 priority and a L2 priority in the range from

0 to 127.

The DIS election is preemptive (unlike OSPF). If a new router boots on the LAN with a

higher interface priority, the new router becomes the DIS. It purges the old pseudonode

LSP and floods a new set of LSPs.
