Answer:

To enhance user bandwidth To isolate traffic between segments

Question 2: What is the purpose of the passive-interface command?

Answer:

allows a router to receive routing updates on an interface but not send updates via that interface Question 3: While configuring RIPv2 on an enterprise network, an engineer enters the command network 192.168.10.0 into router configuration mode. What is the result of entering this command?

Answer:

The interface of the 192.168.10.0 network is sending only version 2 updates Question 4: When would it be more beneficial to use static routing instead of dynamic routing protocols?

Answer:

on a network where dynamic updates would pose a security risk

Question 5: A network administrator configures the port security feature on a switch. The security policy specifies that each access port should allow up to two MAC addresses. When the maximum number of MAC addresses is reached, a frame with the unknown source MAC address is dropped and a notification is sent to the syslog server. Which security violation mode should be configured for each access port?

Answer:

restrict Question 6: Which type of address does a switch use to build the MAC address table?

Answer:

source MAC address Question 7: Which two requirements are used to determine of a route can be considered as an ultimate route in a router's routing table? (2)

Answer:

contain an exit interface contain a next-hop IP address

Question 8: What is the effect of using the switchport port-security command?

Answer:

enables port security on an interface Question 9: If one end of an Ethernet connection is configured for full duplex and the other end of the connection is configured for half duplex, where would late collision be observed?

Answer:

On the half-duplex end of the connection Question 10: What is a characteristic of an IPv4 loopback interface on a Cisco IOS router?

Answer:

It is a logical interface internal to the router Question 11: What two pieces of information are needed in a fully specified static route to eliminate recursive lookups?

Answer:

the interface ID exit interface the IP address of the next-hop neighbor

Question 12: What is a disadvantage of using router-on-a-stick inter-VLAN routing?

Answer:

It does not scale well beyond 50 VLANs Question 13: Which network device can server as a boundary to divide a Layer 2 broadcast domain?

Answer:

router Question 14: Which three IOS troubleshooting commands can help to isolate problems with a static route?

• show version
• ping
• tracert
• show ip route
• show ip interface brief
• show arp

Answer:

ping show ip route show ip interface brief Question 15: Which type or route will require a router to perform a recursive lookup?

Answer:

an ultimate route that is using a next hop IP address on a router that is not using CEF Question 16: In which situation would a technician use the show interfaces switch command?

Answer:

when packets are being dropped from a particular directly attached host Question 17: When would it be more beneficial to use a dynamic routing protocols instead of static routing?

Answer:

on a network where there is a lot of topology changes

Question 18: what is the effect of configuring the ipv6 unicast-routing command on a router?

Answer:

to enable the router as an ipv6 router Question 19: A cisco switch currently allows traffic tagged with VLANs 10 and 20 across trunk port Fa0/5. What is the effect of issuing a switchport trunk allowed vlan 30 command on Fa0/5?

Answer:

It allows only VLAN 30 on Fa0/5 Question 20: What happens to a static route entry in a routing table when the outgoing interface associated with that route goes into the down state?

Answer:

the static route is removed from the routing table Question 21: What does a router uses as the MAC address of the destination when constructing the frame that will go from the router to another device?

Answer:

If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, the router sends an ARP request.Question 22: Which action will bring an error-disabled switch port back to an operational state?

Answer:

Issue the shutdown and then no shutdown interface commands Question 23: What is the purpose of the network command when configuring RIPv2 as the routing protocol?

Answer:

It identifies the interfaces that belong to a specific network

Question 24: What is a characteristic of legacy inter-VLAN routing?

Answer:
