Question 141
Refer to the Exhibit.
After the switch configuration the ping test fails between PC A and PC B Based on the output for switch 1. which error must be corrected?
There is a native VLAN mismatch
Access mode is configured on the switch ports.
The PCs are m the incorrect VLAN
All VLANs are not enabled on the trunk
From the output we see the native VLAN of Switch1 on Gi0/1 interface is VLAN 1 while that of Switch2 is VLAN 99 so there would be a native VLAN mismatch.
Question 142
Which 802.11 frame type is association response?
management
protected frame
control
action
Reference: https://en.wikipedia.org/wiki/802.11_Frame_Types
Question 143
Which API is used in controller-based architectures to interact with edge devices?
overlay
northbound
underlay
southbound
Question 144
Which statement identifies the functionality of virtual machines?
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
Question 145
Which type of address is the public IP address of a NAT device?
outside global
outsdwde local
inside global
insride local
outside public
inside public
NAT use four types of addresses:
* Inside local address – The IP address assigned to a host on the inside network. The address is usually not an IP address assigned by the Internet Network Information Center (InterNIC) or service provider.
This address is likely to be an RFC 1918 private address.
* Inside global address – A legitimate IP address assigned by the InterNIC or service provider that represents one or more inside local IP addresses to the outside world.
* Outside local address – The IP address of an outside host as it is known to the hosts on the inside network.
* Outside global address – The IP address assigned to a host on the outside network. The owner of the host assigns this address.
Question 146
Which option about JSON is true?
uses predefined tags or angle brackets () to delimit markup text
used to describe structured data that includes arrays
used for storing information
similar to HTML, it is more verbose than XML
JSON data is written as name/value pairs.
A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value:
"name":"Mark"
JSON can use arrays. Array values must be of type string, number, object, array, boolean or null..
For example:
{
"name":"John",
"age":30,
"cars":[ "Ford", "BMW", "Fiat" ]
}
Question 147
How do TCP and UDP differ in the way they provide reliability for delivery of packets?
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
Question 148
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 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
Question 149
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.
Question 150
Refer to the exhibit.
A router reserved these five routes from different routing information sources.
Which two routes does the router install in its routing table? (Choose two)
RIP route 10.0.0.0/30
iBGP route 10.0.0.0/30
OSPF route 10.0.0.0/30
EIGRP route 10.0.0.1/32
OSPF route 10.0.0.0/16
