1. What action should a network administrator take to enable VTP pruning on an entire management domain?
A. enable VTP pruning on any client switch in the domain
B. enable VTP pruning on every switch in the domain
C. enable VTP pruning on any switch in the management domain
D. enable VTP pruning on a VTP server in the management domain
Answer:D
2. How does VTP pruning enhance network bandwidth? A. by restricting unicast traffic to across VTP domains
B. by reducing unnecessary flooding of traffic to inactive VLANs
C. by limiting the spreading of VLAN information
D. by disabling periodic VTP updates
Answer:B
3. In the hardware address 0000.0c07.ac0a what does 07.ac represent? A. vendor code
B. HSRP group number
C. HSRP router number
D. HSRP well-known physical MAC address E. HSRP well-known virtual MAC address Answer:E
4. When building an IP multicast domain using PIM which mode assumes that other routers do not want to forward multicast packets for the group?
A. PIM-DM B. PIM-SM C. PIM-RP D. CGMP
E. IGMP snooping
Answer:B
5. Which statement describes Dynamic Trunking Protocol (DTP) mode ‘desirable’?
A. The interface is put into permanent trunking mode and negotiates to convert the link into a trunk link.
B. The interface actively attempts to convert the link to a trunk link.
C. The interface is put into permanent trunking mode but prevented from generating DTP frames. D. The interface is put into a passive mode, waiting to convert the link to a trunk link.
Answer:B
6. Which three statements are correct with regard to the IEEE 802.1Q standard? (Choose three.) A. the packet is encapsulated with a 26 byte header and a 4 byte FCS
B. the IEEE 802.1Q frame format adds a 4 byte field to a Ethernet frame
C. the IEEE 802.1Q frame retains the original MAC destination address
D. the IEEE 802.1Q frame uses multicast destination of 0×01-00-0c-00-00
E. protocol uses point-to-point connectivity
F. protocol uses point-to-multipoint connectivity
Answer:BCE
7. In a customer’s network, VLAN Trunking Protocol (VTP) is running with a domain named main1. VLANs
1,2,3,4,5,10,20 are active on the network. Suddenly the whole network goes down. No traffic is being passed on
VLANs 2,3,4,5,10,20, however traffic passes on VLAN 1 and indicates all switches are operational. Right before
the network problem occurred, a switch named TEST1 was added to the network. What three configuration issues
on TEST1 could be causing the network outage? (Choose three.)
A. TEST1 is configured as a VTP server with a different domain name. B. TEST1 is not configured to participate in VTP.
C. TEST1 is configured as a VTP server with the domain name main1.
D. TEST1 has a lower VTP configuration revision than the current VTP revision.
E. TEST1 has a higher VTP configuration revision than the current VTP revision.
F. TEST1 is configured with only VLAN1. Answer:CEF
8. What is correct about the BGP synchronization command? (Choose two.)
A. Synchronization must be enabled when implementing a multi-homed BGP connection to multiple ISPs.
B. If it is turned ON, a prefix learned from IBGP neighbor is valid only if a non-bgp (IGP) route exists for that
prefix.
C. Synchronization is necessary when peering with an EBGP neighbor. D. Synchronization improves BGP routing convergence.
E. Synchronization can be turned off if all the transit routers in an Autonomous system running full mesh IBGP. Answer:BE
9. Drag the appropriate IS-IS routing term to its correct definition
10. Router RTA is configured as follows:
RTA (config)#router rip
RTA(config-router)#network 10.0.0.0
RTA(config-router)#distribute-list 44 in interface BRI0
RTA(config-router)#exit
RTA(config)#access-list 44 deny 172.16.1.0 0.0.0.255
RTA(config)#access-list 44 permit any
What are the effects of this RIP configuration on router RTA? (Choose two.)
A. no routing updates will be sent from router RTA on interface BRI0 to router RTX B. router RTA will not advertise the 10.0.0.0 network to router RTX
C. the route to network 172.16.1.0 will not be entered into the routing table on router RTA D. user traffic from the 172.16.1.0 network is denied by access-list 44
E. the routing table on router RTA will be updated with the route to router RTW Answer:CE
