Question 131
Which output displays a JSON data representation?
Option A
Option B
Option C
Option D
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" ]
}
JSON can have empty object like "taskId":{}
Question 132
Which command is used to specify the delay time in seconds for LLDP to initialize on any interface?
lldp timer
lldp holdtimt
lldp reinit
lldp tlv-select
Reference: https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960/software/release/12-2_37_ey/configuration/guide/scg/swlldp.pdf+ lldp holdtime seconds: Specify the amount of time a receiving device should hold the informationfrom your device before discarding it+ lldp reinit delay: Specify the delay time in seconds for LLDP to initialize on an interface+ lldp timer rate: Set the sending frequency of LLDP updates in seconds
Question 133
A network engineer must back up 20 network router configurations globally within a customer environment. Which protocol allows the engineer to perform this function using the Cisco IOS MIB?
CDP
SNMP
SMTP
ARP
SNMP is an application-layer protocol that provides a message format for communication between SNMP managers and agents. SNMP provides a standardized framework and a common language used for the monitoring and management of devices in a network.
The SNMP framework has three parts:
+ An SNMP manager
+ An SNMP agent
+ A Management Information Base (MIB)
The Management Information Base (MIB) is a virtual information storage area for network management information, which consists of collections of managed objects.
With SNMP, the network administrator can send commands to multiple routers to do the backup
Question 134
Refer to the exhibit.
An extended ACL has been configured and applied to router R2 The configuration failed to work as intended Which two changes stop outbound traffic on TCP ports 25 and 80 to 10.0.20 0 26 from the 10.0.10 0/26 subnet while still allowing all other traffic? (Choose two )
Add a "permit ip any any" statement to the begining of ACL 101 for allowed traffic.
Add a "permit ip any any" statement at the end of ACL 101 for allowed traffic
The source and destination IPs must be swapped in ACL 101
The ACL must be configured the Gi0/2 interface inbound on R1
The ACL must be moved to the Gi0/1 interface outbound on R2
Question 135
Refer to the exhibit.
Which type of route does R1 use to reach host 10.10.13.10/32?
floating static route
host route
default route
network route
From the output, we see R1 will use the entry "O 10.10.13.0/25 [110/4576] via 10.10.10.1, …" to reach host 10.10.13.10. This is a network route.
Note: "B* 0.0.0.0/0 …" is a default route.
Question 136
Which mode must be used to configure EtherChannel between two switches without using a negotiation protocol?
on
auto
active
desirable
The Static Persistence (or "on" mode) bundles the links unconditionally and no negotiation protocol is used. In this mode, neither PAgP nor LACP packets are sent or received.
Question 137
Which IPv6 address block sends packets to a group address rather than a single address?
2000::/3
FC00::/7
FE80::/10
FF00::/8
FF00::/8 is used for IPv6 multicast and this is the IPv6 type of address the question wants to ask.
FE80::/10 range is used for link-local addresses. Link-local addresses only used for communications within the local subnetwork (automatic address configuration, neighbor discovery, router discovery, and by many routing protocols). It is only valid on the current subnet.
It is usually created dynamically using a link-local prefix of FE80::/10 and a 64-bit interface identifier (based on 48-bit MAC address).
Question 138
Which two capacities of Cisco DNA Center make it more extensible as compared to traditional campus device management? (Choose two)
adapters that support all families of Cisco IOS software
SDKs that support interaction with third-party network equipment
customized versions for small, medium, and large enterprises
REST APIs that allow for external applications to interact natively with Cisco DNA Center
modular design that is upgradable as needed
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.
Question 139
What is the primary effect of the spanning-tree portfast command?
it enables BPDU messages
It minimizes spanning-tree convergence time
It immediately puts the port into the forwarding state when the switch is reloaded
It immediately enables the port in the listening state

Question 140
Refer to the exhibit.
Which command provides this output?
show ip route
show ip interface
show interface
show cdp neighbor
