New Questions 1
Which command sequence can you enter to create VLAN 20 and assign it to an interface on a switch?
A. Switch(config)#vlan 20 Switch(config)#Interface gig x/y Switch(config-if)#switchport access vlan 20
B. Switch(config)#Interface gig x/y Switch(config-if)#vlan 20
Switch(config-vlan)#switchport access vlan 20
C. Switch(config)#vlan 20
Switch(config)#Interface vlan 20
Switch(config-if)#switchport trunk native vlan 20
D. Switch(config)#vlan 20
Switch(config)#Interface vlan 20 Switch(config-if)#switchport access vlan 20
E. Switch(config)#vlan 20
Switch(config)#Interface vlan 20
Switch(config-if)#switchport trunk allowed vlan 20
Answer: A

Which option describes a difference between EIGRP for IPv4 and IPv6?
A. Only EIGRP for IPv6 advertises all connected networks.
B. Only EIGRP for IPv6 requires a router ID to be configured under the routing process-
C. AS numbers are configured in EIGRP but not in EIGRPv3.
D. Only EIGRP for IPv6 is enabled in the global configuration mode.
Answer: B
Explanation:
Router ID- Both EIGRP for IPv4 and EIGRP for IPv6 use a 32-bit number for the EIGRP router ID. The 32-bit router ID is represented in dotted-decimal notation and is commonly referred to as an IPv4 address. If the EIGRP for IPv6 router has not been configured with
an IPv4 address, theeigrp router-idcommand must be used to configure a 32-bit router ID. The process for determining the router ID is the same for both EIGRP for IPv4 and IPv6.
New Questions 3
Which three options are types of Layer 2 network attack? (Choose three.)
A. ARP attacks
B. brute force attacks
C. spoofing attacks
D. DDOS attacks
E. VLAN hopping
F. botnet attacks
Answer: A,C,E
New Questions 4
Which entity assigns IPv6 addresses to end users?
A. ICANN
B. APNIC
C. RIR
D. ISPs
Answer: C
New Questions 5
If three devices are plugged into one port on a switch and two devices are plugged into a different port, how many collision domains are on the switch?
A. 2
B. 4
C. 5
D. 6
Answer: B
New Questions 6
Which two switch states are valid for 802.1w? (Choose two.)
A. listening
B. backup
C. disabled
D. learning
E. discarding
Answer: D,E
Explanation: Port States
There are only three port states left in RSTP that correspond to the three possible operational states. The 802.1D disabled, blocking, and listening states are merged into a unique 802.1w discarding state.
New Questions 7
What is the first step you perform to configure an SNMPv3 user?
A. Configure server traps.
B. Configure the server group.
C. Configure the server host.
D. Configure the remote engine ID.
Answer: B
Explanation:
The first task in configuring SNMPv3 is to define a view. To simplify things, we'll create a view that allows access to the entireinternetsubtree:
router(config)#snmp-server view readview internet included
This command creates a view calledreadview. If you want to limit the view to thesystem tree, for example, replaceinternetwithsystem. Theincludedkeyword states that the specified tree should be included in the view; useexcludedif you wanted to exclude a certain subtree. Next, create a group that uses the new view. The following command creates a group calledreadonly;v3means that SNMPv3 should be used. Theauthkeyword specifies that the entity should authenticate packets without encrypting them;readreadviewsays that the view namedreadviewshould be used whenever members of thereadonlygroup access the router. router(config)#snmp-server group readonly v3 auth read readview
New Questions 8
Which option describes how a switch in rapid PVST+ mode responds to a topology change?
A. It immediately deletes dynamic MAC addresses that were learned by all ports on the switch.
B. It sets a timer to delete all MAC addresses that were learned dynamically by ports in the
same STP instance.
C. It sets a timer to delete dynamic MAC addresses that were learned by all ports on the switch.
D. It immediately deletes all MAC addresses that were learned dynamically by ports in the same STP instance.
Answer: D
Explanation:
Rapid PVST+This spanning-tree mode is the same as PVST+ except that is uses a rapid convergence based on the IEEE 802.1w standard. To provide rapid convergence, the rapid PVST+ immediately deletes dynamically learned MAC address entries on a per-port basis upon receiving a topology change. By contrast, PVST+ uses a short aging time for dynamically learned MAC address entries.
The rapid PVST+ uses the same configuration as PVST+ (except where noted), and the switch needs only minimal extra configuration. The benefit of rapid PVST+ is that you can migrate a large PVST+ install base to rapid PVST+ without having to learn the complexities of the MSTP configuration and without having to reprovision your network. In rapid-PVST+ mode, each VLAN runs its own spanning-tree instance up to the maximum supported.
New Questions 9
What should be part of a comprehensive network security plan?
A. Allow users to develop their own approach to network security.
B. Physically secure network equipment from potential access by unauthorized individuals.
C. Encourage users to use personal information in their passwords to minimize the
likelihood of passwords being forgotten.
D. Delay deployment of software patches and updates until their effect on end-user equipment is well known and widely reported
E. Minimize network overhead by deactivating automatic antivirus client updates.
Answer: B
Explanation:
Computer systems and networks are vulnerable to physical attack; therefore, procedures should be implemented to ensure that systems and networks are physically secure. Physical access to a system or network provides the opportunity for an intruder to damage, steal, or corrupt computer equipment, software, and information. When computer systems are networked with other departments or agencies for the purpose of sharing information, it is critical that each party to the network take appropriate measures to ensure that its system will not be physically breached, thereby compromising the entire network. Physical security procedures may be the least expensive to implement but can also be the most costly if not implemented. The most expensive and sophisticated computer protection software can be overcome once an intruder obtains physical access to the network.
