Which statement identifies the functionality of virtual machines?

The hypervisor can virtualize physical components including CPU. memory, and storage

Virtualized servers run most efficiently when they are physically connected to a switch that is separate from the hypervisor

The hypervisor can virtualize physical components including CPU. memory, and storage

Each hypervisor can support a single virtual machine and a single software switch

The hypervisor communicates on Layer 3 without the need for additional resources

Which option about JSON is true?

used to describe structured data that includes arrays

uses predefined tags or angle brackets () to delimit markup text

used to describe structured data that includes arrays

similar to HTML, it is more verbose than XML

How do TCP and UDP differ in the way they provide reliability for delivery of packets?

TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking for sequencing

TCP is a connectionless protocol that does not provide reliable delivery of data, UDP is a connection-oriented protocol that uses sequencing to provide reliable delivery.

TCP does not guarantee delivery or error checking to ensure that there is no corruption of data UDP provides message acknowledgement and retransmits data if lost.

TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking for sequencing

TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake

Which two command sequences must you configure on switch to establish a Layer 3 EtherChannel with an open-standard protocol? (Choose two )

interface GigabitEthernet0/0/1 channel-group 10 mode active

interface port-channel 10 no switchport ip address 172.16.0.1.255.255.255.0

interface GigabitEthernet0/0/1 channel-group 10 mode on

interface GigabitEthernet0/0/1 channel-group 10 mode active

interface GigabitEthernet0/0/1 channel-group 10 mode auto

interface port-channel 10 switchport switchport mode trunk

interface port-channel 10 no switchport ip address 172.16.0.1.255.255.255.0

What is an advantage of Cisco DNA Center versus traditional campus device management?

It supports numerous extensibility options including cross-domain adapters and third-party SDKs.

It supports high availability for management functions when operating in cluster mode.

It enables easy autodiscovery of network elements m a brownfield deployment.

It is designed primarily to provide network assurance.

By default, how Does EIGRP determine the metric of a route for the routing table?

it uses the bandwidth and delay values of the path to calculate the route metric

it uses a default metric of 10 for all routes that are learned by the router

it uses a reference Bandwidth and the actual bandwidth of the connected link to calculate the route metric

it counts the number of hops between the receiving and destination routers and uses that value as the metric

What is a difference between local AP mode and FiexConnet AP mode?

Local AP mode creates two CAPWAP tunnels per AP to the WLC

FiexConnect AP mode fails to function if the AP loses connectivity with the WLC

FlexConnect AP mode bridges the traffic from the AP to the WLC when local switching is configured

Local AP mode causes the AP to behave as if it were an autonomous AP

Which function does the range of private IPv4 addresses perform?

allows multiple companies to each use the same addresses without conflicts

provides a direct connection for hosts from outside of the enterprise network

ensures that NAT is not required to reach the internet with private range addressing

enables secure communications to the internet for all external hosts

What event has occurred if a router sends a notice level message to a syslog server?

An ICMP connection has been built

An interface line has changed status

Refer to the exhibit. What two conclusions should be made about this configuration? (Choose two )

The spanning-tree mode is Rapid PVST+

The spanning-tree mode is Rapid PVST+

The spanning-tree mode is PVST+

The root port is FastEthernet 2/1

It allows multiple operating systems and applications to run independently on one physical server.

It allows a physical router to directly connect NICs from each virtual machine into the network

It requires that some servers, virtual machines and network gear reside on the Internet
