VTPv3 Sim
You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.
Question 1
You are connecting the New_Switch to the LAN topology; the switch has been partially configured and you need to complete the rest of configuration to enable PC1 communication with PC2. Which of the configuration is correct?
A. vtp domain CCNP_TEST
vtp password cisco123
vtp version 3
vtp mode server
interface e0/0
switchport mode access
switch port access vlan 100
B. vtp domain CCNP_TEST
vtp password cisco123
vtp version 3Revision
vtp mode client
interface e0/0
switchport mode access
switchport access vlan 200
C. vtp domain CCNP_TEST
vtp password cisco123
vtp version 2
vtp mode client
interface e0/0
switchport mode access
switchport access vlan 100
D. vtp domain CCNP
vtp password cisco
vtp version 3
vtp mode client
interface e0/0
switchport mode access
switchport access vlan 100
E. vtp domain CCNP
vtp password cisco
vtp version 2
vtp mode transparent
interface e0/0
switchport mode access
switchport access vlan 200
Answer: D
لمعرفة إعدادات الـVTP ناخذها من أحد السويتشين Sw1 أو Sw2 بأستخدام اﻷمر :-
show vtp status
SW1#sh vtp status
VTP Version capable : 1 to 3
VTP version running : 3
VTP Domain Name : CCNP
VTP Pruning Mode : Enabled
VTP Traps Generation : Disabled
Device ID : aabb.cc00.0b00
Feature VLAN:
VTP Operating Mode : Server
Number of existing VLANs : 8
Number of existing extended VLANs : 0
Maximum VLANs supported locally : 4096
Configuration Revision : 12
Primary ID : aabb.cc00.0b00
Primary Description : Sw1
MD5 digest : 0xFF 0xC5 0x69 0xEC 0x2E 0xD6 0xAA 0x3C
0xA8 0x12 0x8D 0x4D 0x17 0x5D 0x74 0xB9
من المخرجات للأمر show vtp status على السويتش sw1 :-
+ VTP is running version 3
+ VTP Domain is “CCNP”
+ Sw1 is the VTP Server
ولمعرفة الرقم السري لـVTP ننفذ اﻷمر sh vtp password على أحد السويتشين Sw1 أو Sw2
SW1#sh vtp password
VTP Password: cisco
وبمأن السويتش الجديد سيكون عميل client فلذلك تكون إعداداته كما يلي:-
vtp domain CCNP
vtp password cisco
vtp version 3
vtp mode client
لاحظ أيضا أنه بامكنك تشغيل السويتش الجديد على vtp version 2 or 3 لكن السويتش الجديد متصل به جهاز كمبيوتر على vlan 100 لذلك الجواب الصحيح خو D
Question 2
Refer to the configuration. For which configured VLAN are untagged frames sent over trunk between SW1 and SW2?
A. VLAN1
B. VLAN 99
C. VLAN 999
D. VLAN 40
E. VLAN 50
F. VLAN 200
G. VLAN 300
Answer: B
بتنفيذ اﻷمر show interfaces trunk على السويتشين Sw1 & Sw2
SW1#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Et1/2 on 802.1q trunking 99
Et1/3 on 802.1q trunking 99
Et2/0 on 802.1q trunking 99
Et2/1 on 802.1q trunking 99
Et2/2 on 802.1q trunking 99
Et2/3 on 802.1q trunking 99
SW2#show interfaces trunk
Port Mode Encapsulation Status Native vlan
Et1/2 on 802.1q trunking 99
Et1/3 on 802.1q trunking 99
Et2/0 on 802.1q trunking 99
Et2/1 on 802.1q trunking 99
Et2/2 on 802.1q trunking 99
Et2/3 on 802.1q trunking 99
السويتشين Sw1 & Sw2 متصلين مع بعض عن طريق المنفذين E2/3 & E2/3 لذلك يجب أن يكون كلا الطرفين لهما نفس native vlan 99
Question 3
You are adding new VLANs: VLAN500 and VLAN600 to the topology in such way that you need to configure SW1 as primary root for VLAN 500 and secondary for VLAN 600 and SW2 as primary root for VLAN 600 and secondary for VLAN 500. Which configuration step is valid?
A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2
B. Configure VLAN 500 and VLAN 600 on SW1 only
C. Configure VLAN 500 and VLAN 600 on SW2 only
D. Configure VLAN 500 and VLAN 600 on SW1 ,SW2 and SW4
E. On SW2 configure VTP mode as off and configure VLAN 500 and VLAN 600; configure back to vtp server mode.
Answer: A
أولا سنقوم بتنفيذ اﻷمر show vtp status على السويتشين SW1 & SW2 سنلاحظ أن كلاهما “Server” mode لذلك الخيار :-
A. Configure VLAN 500 & VLAN 600 on both SW1 & SW2.
صحيح
ملاحظة هامة :-
In practical we only need to create VLANs on one of the “Server” switch and these VLANs will be propagated automatically to others “Server” and “Client” switch. But maybe it is not the answer Cisco wants (as it makes both answers B & C are correct).
Question 4
Examine the VTP configuration. You are required to configure private VLANs for a new server deployment connecting to the SW4 switch. Which of the following configuration steps will allow creating private VLANs?
A. Disable VTP pruning on SW1 only
B. Disable VTP pruning on SW2 only
C. Disable VTP pruning on SW4 only
D. Disable VTP pruning on SW2, SW4 and New_Switch
E. Disable VTP pruning on New_Switch and SW4 only.
Answer: C
لكي نقوم بإنشاء private vlans على الـsw4 الذي هو ملاحظة هامة :-حاليا في وضع vtp client لابد تغييره إلى VTP Transparent mode لكن هذا ليس ضمن الخيارات لذلك Disable VTP pruning on SW4 only تعتبر اجابه صحيحة ﻷنه يتم تعطيلها قبل تحويله إلى VTP Transparent mode
ملاحظة هامة :-
Note: Unlike VTP version 1 and 2 in which VTP pruning is enabled on VTP Server only, VTP version 3 requires VTP pruning must be enabled on all the switches in the VTP domain so we can also disable VTP pruning on each switch separately. Here is the link for your reference: http://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12-2_55_se/configuration/guide/3750xscg/swvtp.html
“With VTP versions 1 and 2, when you enable pruning on the VTP server, it is enabled for the entire VTP domain. In VTP version 3, you must manually enable pruning on each switch in the domain.”
