You study the exhibit carefully. What can be drawn about VLANs 200 and 202 from the exhibit?

28

A. VLAN 200 carries traffic from promiscuous ports to isolated, community, and other promiscuous ports in the same VLAN. VLAN 202 carries traffic between community ports and to promiscuous ports.
B. VLAN 200 carries traffic from promiscuous ports to isolated, community, and other promiscuous ports in the same VLAN. VLAN 202 carries traffic from isolated ports to a promiscuous port.
C. VLAN 202 carries traffic from promiscuous ports to isolated, community, and other promiscuous ports in the same VLAN. VLAN 200 carries traffic from isolated ports to a promiscuous port.
D. VLAN 202 carries traffic from promiscuous ports to isolated, community, and other promiscuous ports in the same VLAN. VLAN 200 carries traffic between community ports and to promiscuous ports.

QUESTION NO: 27
You administer a network that uses two routers, R1 and R2, configured as an HSRP group to provide redundancy for the gateway. Router R1 is the active router and has been configured as follows:

R1#configure terminal
R1(config)#interface fa0/0
R1(config-if)#ip address 10.10.0.5 255.255.255.0
R1(config-if)#standby 1 priority 150
R1(config-if)#standby preempt delay minimum 50
R1(config-if)#standby 1 track interface fa0/2 15
R1(config-if)#standby 1 ip 10.10.0.20

Which of the following describes the effect the standby preempt delay minimum 50 command will have on router R1? (Select the best answer.)
A. The HSRP priority for router R1 will increase to 200.
B. Router R1 will become the standby router if the priority drops below 50.
C. The HSRP priority for router R1 will decrease to 50 points when Fa0/2 goes down.
D. Router R1 will wait 50 seconds before attempting to preempt the active router.
Answer: D

QUESTION NO: 28
Refer to the exhibit. Consider the following scenario:
Packet A is a TCP packet from host 10.2.2.2., port 65000, going to host 10.1.1.1 on the SMTP port.
Assuming that this ACL is properly applied on the switch, if this packet is fragmented, which two of the following statements are true, based on the configuration shown in the exhibit? (Choose two.)

27
A. The first fragment matches the first ACE because it contains all the Layer 3 information required by the ACE.
B. The first fragment matches the first ACE as if it were a complete packet because all Layer 4 information is present.
C. The remaining fragments also contain the needed Layer 4 information and will be permitted.
D. The remaining fragments also match the first ACE, even though they do not contain the Layer 4 port information, because the first ACE only checks Layer 3 information when applied to fragments.
E. The remaining fragments will be dropped because the needed Layer 4 information is missing in fragmented packets. An additional established keyword needs to be added to the ACE.
Answer: BD

QUESTION NO: 30
A new floor has been added to the enterprise campus network, providing client access for desktop PCs, laptops, and IP phones for employees and guests. During verification, a few desktop PCs have limited corporate access but not Internet access. Most other desktop PCs, all laptops, and IP phones are working correctly. Additional information indicates that the desktop PCs are obtaining IP host addresses from the DHCP server, which is intended for only the IP phones. Where should troubleshooting about this connectivity issue be focused?
A. client network configuration
B. VLAN mapping
C. DHCP server and options
D. DNS
E. routing protocols
F. first-hop redundancy protocol
Answer: B
