Hotspot 2: Topology Question
640-802 CCNA Hotspot Topology Exhibit
Question 1:
Note: host 172.30.4.4 is wrongly given in Question the correct host must be 172.30.0.4
Answers: 702
Explanation:The destination layer 2 address is a DLCI for frame-relay network. The destination host packet address is 172.30.0.4 corresponding DLCI is 702.
This can be confirmed by looking at the show frame-relay map output which shows the frame-relay map statements for layer 3 address to its corresponding layer 2 address IP 172.30.0.4 is mapped to DLCI 702 .
Question 2:
Answers: frame-relay map ip 172.30.0.3 196 broadcast
Explanation:
The show frame-relay map command above output provides the dynamic mapping for S-AMER (.3 as per topology the complete address is 172.30.0.3) to DLCI 196.
To create a static frame-relay map on dubai router to S-AMER we use the following command
Syntax: frame-relay map protocol protocol-address dlci [broadcast]
frame-relay map ip 172.30.0.3 196 broadcast
Question 3:
Answers: The serial connection to the MidEast branch office
Explanation:
By seeing the partial running config provided for Dubai router ... We can identify what encapuslation type is configured on each interface
Interface serial 1/0 : encapsulation frame-relay
Interface serial 1/2 and serial 1/3 : Both have encapsulation ppp
Interaface serial 1/1: Has no config info on encapsulation type this determines the default encapsulation (HDLC) is not changed on this interface.
Serial 1/1 is connection to MidEast branch office from Dubai router which has the default encapsulation.
Question 4:
Answers: No password is required.
Explanation: The serial connection between the mideast and Dubai router is having the default WAN encapsulation of HDLC. Since, HDLC requires no password to be set for connection establishment, "no password is required" is the correct answer.

Download Cisco Unified Communications Manager 6.0.1 – Install DVD
Cisco Unified Communications Manager (CUCM), formerly Cisco Unified CallManager and Cisco CallManager (CCM), is a software based IP call agent platform sold by Cisco Systems. Cisco renamed the product to Unified Communications Manager. Version 6 was supposed to merge all features of the Linux appliance (SIP support and licensing requirements) between the Linux platform and Windows version. The released version of Unified Communications Manager will not support the Windows platform.
This version added an intercom feature between endpoints, and integrated Mobility Manager (single number reach to multiple destinations, IP Phone, Cell Phone, etc).

How to Configure Drive on Solaris for Veritas Netbackup
Understanding the SCSI Passthru Drivers
NetBackup Media Manager provides its own driver for communicating with SCSI-controlled robotic peripherals.
This driver is called the SCSA (Generic SCSI passthru driver), also referred to as the sg driver.
To manage the sg driver
Perform the following steps as the root user.
1. Determine if an sg driver is loaded by using the following command:
/usr/sbin/modinfo | grep sg
141 fc580000 2d8c 116 1 sg (SCSA Generic Revision: 3.4d)
153 fc7fa000 1684 49 1 msgsys (System V message facility)
2. Remove the existing driver:
/usr/sbin/rem_drv sg
/usr/bin/rm -f /kernel/drv/sg.conf
Install SG Driver
To install the driver run the following command:
/usr/openv/volmgr/bin/driver/sg.install
Once the driver has been installed, it is not necessary to reboot the system or run the sg.install command during or after each system boot.

Netbackup – How do I expire, delete tapes from the database
NetBackup\bin\admincmd\bpimmedia -mediaid -L
If there are no images that you need, expire the tape:
NetBackup\bin\admincmd\bpexpdate -m -d 0 -host -force
This expires the images in the media database which resides specifically on the media server.
