This Exam contains:

-Guarantee passing score -99 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: A technician is configuring a router for a small company with multiple WLANs and doesn't need the complexity of a dynamic routing protocol. What should be done or checked?

Answer:

Create static routes to all internal networks and a default route to the Internet Question 2: A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?

Answer:

To reduce outsiders intercepting data or accessing the wireless network by using a well-known address range Question 3: After a host has generated an IPv6 address by using the DHCPv6 or SLAAC process, how does the host verify that the address is unique and therefore useable?

Answer:

The host sends an ICMPv6 neighbor solicitation message to the DHCP or SLAAC-learned address and if no neighbor advertisement is returned, the address is considered unique

Question 4: A static route has been configured on a router. However, the destination network no longer exists. What should an administrator do to remove the static route from the routing table?

Answer:

Remove the route using the no ip route command Question 5: Refer to the exhibit. Based on the exhibited configuration and output, why is VLAN99 missing?

Answer:

Because VLAN99 has not yet been created Question 6: Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?

Answer:

broadcast DHCPREQUEST

Question 7: Match the link state to the interface and protocol status

Answer:

Disabled- Administratively down Layer 1 problem- down/down Layer 2 problem- up/down Operational- up/up Question 8: What action takes place when a frame entering a switch has a unicast desitnation MAC address appearing in the MAC address table?

Answer:

The switch forwards the fame out the specified port

Question 9: Which network attack is mitigated by enabling BPDU guard?

Answer:

Rouge switches on a network Question 10: Refer to the exhibit. What is the metric to forward a data packet with the IPv6 destination address 2001:db8:acad:3:240:bff:fed4:9dd2?

Answer:

2682112

Question 11: The exhibit shows two PCs called PC A and PC B, two routes called R1 and R2, and two switches. PC A has the address 172.16.1.1/24 and is connected to a switch and into an interface on R1 that has the IP address 172.16.1.254. PC B has the address 172.16.2.1/24 and is connected to a switch that is connected to another interface on R1 with the IP address 172.16.2.254. The serial interface on R1 has the address 172.16.3.1 and is connected to the serial interface on R2 that has the address 172.16.3.2/24. R2 is connected to the internet cloud. Which command will create a static route on R2 in order to reach PC B?

Answer:

R2(config)# ip route 172.16.2.0 255.255.255.0 172.16.3.1 Question 12: Which command will start the process to bundle two physical interfaces to create an EtherChannel group via LACP?

Answer:

interface range GigabitEthernet0/4-5 Question 13: Refer to the exhibit. A network administrator has added a new subnet to the network and needs hosts on that subnet to receive IPv4 addresses from the DHCPv4 server.What two commands will allow the hosts on the new subnet to receive addresses from the DHCPv4 server?

Answer:

R1(config)#interface g0/0 R1(config-if)#ip helper-address 10.2.0.250

Question 14: Refer to the exhibit. Host A has sent a packet to Host

• What will be the source MAC and IP address on the packet when it arrives at Host B?

Answer:

Source MAC: 00E0.FE91.7799 (last router before destination)

Source IP: 10.1.1.10 (original host IP)

Question 15: Which two statements are characteristics of routed ports on a multilayer switch?

Answer:

-In a switched network, they are mostly configured between switches at the core and distribution layers -They are not associated with a particular VLAN Question 16: A company is deploying a wireless network in the distribution facility in a Boston suburb. The warehouse is quite large and it requires multiple access points to be used. Because some of the company devices still operate at 2.4GHz, the network administrator decides to deploy the 802.11g standard. Which channel assignments on the multiple access points will make sure that the wireless channels are not overlapping?

Answer:

Channel 1, 6, 11 Question 17: What network attack seeks to create a DoS for clients by preventing them from being able to obtain a DHCP lease?

Answer:

DHCP starvation Question 18: Refer to the exhibit. All the displayed switches are Cisco 2960 switches with the same default priority and operating at the same bandwidth. Which three ports will be STP designated ports?

Answer:

-fa0/13 -fa0/21 -fa0/10 Question 19: What action takes place when a frame entering a switch has a multicast destination MAC address?

Answer:

The switch will forward the frame out all ports except the incoming port Question 20: Which type of static route is configured with a greater administrative distance to provide a backup route to a route learned from a dynamic routing protocol?

Answer:

Floating static route

Question 21: Select the three PAgP channel establishment modes.

Answer:

-Auto -Desirable -On Question 22: 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
