(Based on a topology shown with one core, two distribution and two access switches on each distribution switch, with redundant links and bandwidth mentioned.)
A. ASW1 to DWS1 to core
B. ASW1 to DWS2 to core
C. ASW1 to DSW1 to DSW2 to core

Answer: B
Real Questions
If HSRP group number is 45 what would be the MAC address?
(Basically conversion of digit to hexadecimal with group of 16.)
A. 00-00-0C-07-AC-2D
B. 0000-0C07-AC45
C. 0000-070C-AC2D
D. 0000-C004-ACD2
Answer: A
Explanation:

CISCO_ID :HSRP_ID:GROUP_ID
2d=45
Real Questions
Select a valid VRRP configuration from a list of possible configurations. (Choose three.)
A. vrrp [group-number] ip [ip-address]
B. vrrp [group-number] priority [priority]
C. vrrp [group-number] preempt
D. standby [group number] priority [priority]
E. standby [group number] preempt
Answer: ABC
Explanation:
You can eliminate configurations with the word `standby’, as that would be HSRP, not VRRP. Also, I think the options that put things like vrrp group 1 ip x.x.x.x are wrong.
You don’t need the word `group’ in the configuration line. The number 1 is the group number. Anyway, just take a good look a t a few valid VRRP configuration examples so that you will be able to recognize invalid ones.
Real Questions
Which two secondary VLAN types of Private VLANs (PVLANs)? (Choose Two)
A. community
B. isolated
C. promiscuous
D. host
Answer: AB
Explanation:
Secondary VLANs provide Layer 2 isolation between ports within the same private VLAN domain.
There are two types of secondary VLANs:
• Isolated VLANs – Ports within an isolated VLAN cannot communicate with each other at the Layer 2 level.
• Community VLANs – Ports within a community VLAN can communicate with each other but cannot communicate with ports in other communities at the Layer 2 level
Real Questions
What types of SDM templates you can use in switch? (Choose four)
A. Access
B. Default
C. Routing
D. VLANs
Answer: ABCD
Explanation:
+ Access – The access template maximizes system resources for access control lists (ACLs) to accommodate a large number of ACLs.
+ Default – The default template gives balance to all functions.
+ Routing – The routing template maximizes system resources for IPv4 unicast routing, typically required for a router or aggregator in the center of a network.
+ VLANs – The VLAN template disables routing and supports the maximum number of unicast MAC addresses. It would typically be selected for a Layer 2 switch.

Real Questions
There was another Exhibit about port priority- Core switch connected to 2 dis switches which connected 2 ASW. PC1 is connected to DSW1 and DSW2 (Root Bridge). Link connected from PC1 to DSW2 is 4Gbps and DSW1 is 10Gbps. There is etherchannel trunk between DSW1 and DSW2. Default port prioirty is configured.
Change in port priority so traffic goes through DSW1 to DSW2
A. DSW1: spanning-tree port priority 16
B. DSW1: interface g1/0
C. DSW2: spanning-tree port priority 16
D. DSW2: interface g1/0
E. DSW1: spanning-tree port priority 0
Answer: AB
