What is a DHCP client?
A.
a host that is configured to request an IP address automatically
B.
a server that dynamically assigns IP addresses to hosts
C.
a workstation that requests a domain name associated with its IP address
D.
a rooter that statically assigns IP addresses to hosts
a host that is configured to request an IP address automatically
What causes a port to be placed in the err-disabled state?
A.
latency
B.
port security violation
C.
shutdown command issued on the port
D.
nothing plugged into the port
port security violation
Explanation: This mode is the default violation mode; when in this mode, the switch will
automatically force the switchport into an error disabled (err-disable) state when a violation
occurs. While in this state, the switchport forwards no traffic. The switchport can be brought
out of this error disabled state by issuing the errdisable recovery cause CLI command or by
disabling and reenabling the switchport.
Which technology allows for multiple operating systems to be run on a single host
computer?
A.
virtual routing and forwarding
B.
network port ID visualization
C.
virtual device contexts
D.
server visualization
server visualization
Refer to the exhibit.
When PC-A sends traffic to PC-B, which network component is in charge of receiving the
packet from PC-A verifying the IP addresses, and forwarding the packet to PC-B?
A.
Layer 2 switch
B.
Router
C.
Load balancer
D.
firewall
Router
Explanation: PC-A and PC-B are not in the same network. Switches send traffic in layer 2
and within the same VLA while routers route traffic to different subnet and at layer 3.
What is a network appliance that checks the state of a packet to determine whether the packet is legitimate?
A.
Layer 2 switch
B.
load balancer
C.
firewall
D.
LAN controller
firewall
How does QoS optimize voice traffic?
A.
reducing bandwidth usage
B.
by reducing packet loss
C.
by differentiating voice and video traffic
D.
by increasing jitter
by differentiating voice and video traffic
Which two capacities of Cisco DNA Center make it more extensible as compared to traditional campus device management? (Choose two)
A.
adapters that support all families of Cisco IOS software
B.
SDKs that support interaction with third-party network equipment
C.
customized versions for small, medium, and large enterprises
D.
REST APIs that allow for external applications to interact natively with Cisco DNA Center
E.
modular design that is upgradable as needed
SDKs that support interaction with third-party network equipment
REST APIs that allow for external applications to interact natively with Cisco DNA Center
Explanation: Cisco DNA Center offers 360-degree extensibility through four distinct types
of platform capabilities:+ Intent-based APIs leverage the controller and enable business
and IT applications to deliver intent to the network and to reap network analytics and
insights for IT and business innovation.+ Process adapters, built on integration APIs, allow
integration with other IT and network systems to streamline IT operations and processes.+
Domain adapters, built on integration APIs, allow integration with other infrastructure
domains such as data center, WAN, and security to deliver a consistent intent-based
infrastructure across the entire IT environment.+ SDKs allow management to be extended
to third-party vendor’s network devices to offer support for diverse environments.
