ASCII
base64
binary

An organization has decided to start using cloud-provided services.Which cloud service allows the organization to install its own operating system on a virtual machine?
platform-as-a-service
software-as-a-service
infrastructure-as-a-service
network-as-a-service
What is a benefit of using a Cisco Wireless LAN Controller?
Central AP management requires more complex configurations
Unique SSIDs cannot use the same authentication method
It supports autonomous and lightweight APs
It eliminates the need to configure each accesspoint individually
When configuring IPv6 on an interface, which two IPv6 multicast groups are joined?
2000::/3
2002::5
FF02::1
FF02::2
Which IPv6 address type provides communication between subnets and cannot route on the Internet?
global unicast
unique local
link-local
multicast
Which command prevents passwords from being stored in the configuration as plaintext on a router or switch?
enable secret
service password-encryption
username Cisco password encrypt
enable password
Which type of wireless encryption is used for WPA2 in pre-shared key mode?
TKIP with RC4
RC4
AES-128
AES-256
How do TCP and UDP differ in the way that they establish a connection between two endpoints?
TCP uses synchronization packets, and UDP uses acknowledgment packets.
UDP uses SYN, SYN ACK and FIN bits in the frame header while TCP uses SYN, SYN ACK and ACK bits.
UDP provides reliable message transfer and TCP is a connectionless protocol.
TCP uses the three-way handshake and UDP does not guarantee message delivery.
Which configuration is needed to generate an RSA key for SSH on a router?
Configure the version of SSH.
Configure VTY access.
Create a user with a password.
Assign a DNS domain name.
Which attribute does a router use to select the best path when two or more different routes to the same destination exist from two different routing protocols?
dual algorithm
metric
administrative distance
hop count
Router A learns the same route from two different neighbors, one of the neighbor routers is an OSPF neighbor and the other is an EIGRP neighbor. What is the administrative distance of the route that will be installed in the routing table?
20
90
110
115
What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?
The Layer 2 switch drops the received frame.
The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN.
The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning.
The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table.
Two switches are connected and using Cisco Dynamic Trunking Protocol SW1 is set to Dynamic Desirable. What is the result of this configuration?
The link is in a down state.
The link is in an error disables state
The link is becomes an access port.
The link becomes a trunk port.
When a site-to-site VPN is used, which protocol is responsible for the transport of user data?
IKEv2
IKEv1
IPsec
MD5
A router running EIGRP has learned the same route from two different paths. Which parameter does the router use to select the best path?
cost
adminstrative distance
metric
as-path
Which two are features of IPv6? (Choose two.)
anycast
broadcast
multicast
podcast
allcast
Which command enables IPv6 forwarding on a Cisco router?

: :1
::
2000::/3
0::/10
AAA stands for authentication, authorization, and accounting
False
True
How does STP prevent forwarding loops at OSI Layer 2?
TTL
MAC address forwarding
Collision avoidance
Port blocking
