QUESTION 11

All secure domain routers (SDRs) have shared attribute and resources. Which three resources are shared all SDRs? (Choose three.)

 

A.

privilege-level configuration

B.

fabric cards

C.

SNMP traps

D.

admin-level configuration

E.

exec-level configuration

 

Correct Answer: BCD

Explanation:

1.4. SP high end product

There are shared attributes and resources common to all SDRs. It is important to note that the shared resources are critical to the system’s overall operation. Some examples of shared resources that are common to SDR are:

 

Environmental resources.

Power supplies.

Fan trays.

Fan controllers.

Fabric cards.

 

Software related:

* Exec-level configuration. Configuration in admin mode can affect all SDRs.

* Admin-level configuration. Admin-level command can impact owner SDR and non-owner SDRs.

* Process instances. A few processes are shared, systemwide processes such as LRd (SDR Deamon).

 

Management:

* SNMP traps. For example, shared power, fans, and fabric-related traps.

* SNMP polling. Shared for power, fans, and fabric-related MIBS.

* Syslogs. Some non-owner SDRs are logged to the owner SDR.

* Shared environment variables.

 

 

QUESTION 12

B.

The fabric and system controller module are shared by all logical routers.

C.

Each logical router has a distinct fabric and system controller module

D.

QUESTION 13

There are two cabling schemes to choose from when implementing a Cisco CRS-1 multi shelf system:single module cabling and multi module cabling. What is the maximum capacity of the LCCs that are supported in multi module cabling?

 

A.

9 LCCs

B.

7 LCCs

C.

10 LCCs

D.

6 LCCs

E.

8 LCCs

 

Correct Answer: A

Explanation:

1.4. SP high end product

A single card or multiple cardscan be grouped as a fabric plane. Single-module cabling requires eight S2 cards in the fabric card chassis. In this mode, each S2 is dedicated to a plane number and cabled to the appropriate line card chassis plane. If your network requires more than three LCC in the multi shelf system, this is achieved using the multi module configuration. Multi module configuration provides capacity to add up to nine LCCs.

 

 

QUESTION 14

Process-level redundancy is implemented by a system manager process that creates the standby process. What two functions are provided by the system-level process called Qnet Symlink Manager (QSM)? (Choose two.)

 

A.

backing up the information for the broken connections

B.

provides common information for connecting processes and services

C.

detection of a failed connection

D.

provides an abstract name for a process or service

E.

distribution of symbolic link information

 

Correct Answer: DE

Explanation:

Process-Level Redundancy

Process-level redundancy is implemented by a system manager process creating the standby process.

Because the active process created the standby process, the active process has all the information that it needs to communicate with the standby process. The active process uses a checkpoint database to share running state with the standby process. Symbolic links and abstract names are used to identify the processes. Clients do not see the standby process until the active goes away. If a process fails and it has created a standby process, asystem-level process called QNet Symlink Manager (QSM) and a library called Event Connection Manager (ECM) are used to re-establish links from the clients to the processes.

 

QSM provides:

Distribution of symbolic link information

Abstract name for a process or service

ECM provides:

Common information for connecting processes and services

Detection of broken connections

Only processes considered essential by development engineers are designated to support process-level redundancy. This is not auser-configurable option. Clients have to reconnect to the “new” active process (the “original” standby process) when they detect that the active process has failed. Clients can connect to it using the symbolic links and abstract names. The new active process creates a new standby process.

The general steps in process redundancy are:

The active process dies.

The standby process becomes the active process.

A new standby process starts.

The new active process begins sending updates to the new standby process. Clients begin using the new active process through the symbolic links and abstract names.

 

 

QUESTION 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

 

Correct 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.

QUESTION 20

What three major tasks are performed by a Designated Intermediate System in an ISIS pseudonode environment? (Choose three.)

 

A.

updating the pseudonode LSP

B.

maintaining pseudonode link-state information

C.

creating the pseudonode LSP

D.

flooding LSPs over the LAN

E.

election of the pseudonode

 

Correct Answer: ACD

Explanation:

Two major tasks are performed by the DIS:

Creating andupdating pseudonode LSP for reporting links to all systems on the broadcast subnetwork. See the Pseudenode LSP section for more information.

Flooding LSPs over the LAN.

 

Flooding over the LAN means that the DIS sends periodic complete sequence numberprotocol data units (CSNPs) (default setting of 10 seconds) summarizing the following information:

 

LSP ID

Sequence Number

Checksum

Remaining Lifetime

 

The DIS is responsible for flooding. It creates and floods a new pseudonode LSP for each routing level in which it is participating (Level 1 or Level 2) and for each LAN to which it is connected. A router can be the DIS for all connected LANs or a subset of connected LANs, depending on the IS-IS priority or the Layer 2 address.

 

The DIS will also create andflood a new pseudonode LSP when a neighbor adjacency is established, torn down, or the refresh interval timer expires. The DIS mechanism reduces the amount of flooding on LANs.
