Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet to an external server at the IP address 209.165.200.254 across a router R1 that is running dynamic NAT. (Not all options are used.)
A network administrator can successfully ping the server at www.cisco.com, but cannot ping the company web server located at an ISP in another city. Which tool or command would help identify the specific router where the packet was lost or delayed?
traceroute
ipconfig
telnet
netstat

PUT
GET
Match the term to the RESTAPI request http://example.com/update/person?id=42&email=person%40example.com. (Not all options are used.)
Which HTTP status code category is used in the response to indicate that a REST API request contains an error on the client side?
1xx
2xx
3xx
4xx
5xx
Refer to the exhibit. A network administrator is using a Python script to test a REST API request. The traceback message indicates that there is an error in the URI. What is the error?
The protocol is wrong.
The resource path is wrong.
The SSL certificate is invalid.
The destination web host address is invalid.
What are two requirements for an application to communicate with a webhook provider? (Choose two.)
The application must support JSON.
The application must always be running.
The application must register a URL with the webhook provider.
The host where the application is running must have an SSH client installed.
The host where the application is running must have an SSH server running.
A student is learning network automation by using a REST API. The student sends a request to a network device and receives a response with the status code of 202. What does this status code mean?
The request was understood but has been rejected by the server.
The request was successful and typically includes a payload.
The request has been accepted for processing, but the processing has not been completed.
Because of a server error, the request cannot be fulfilled.
What are two characteristics of stateless applications? (Choose two.)
They must run on container orchestrators like Kubernetes.
They can be freely scaled across available capacity without disrupting ongoing customer connections.
They can be scaled only by redeploying them and destroying the data that users or operators previously needed.
They maintain the user state within the local user machine so that automation can work non-destructively.
They can store a user state in an accessible database separate from application servers and other components.
What is a characteristic of the continuous integration component of the CI/CD philosophy for software development?
Code changes are continually merged with the main branch of the application, so change sets are small.
Code changes are tested and integrated with the main branch then tested again before they are deployed into production.
Code is constantly deployed into production where users serve as the final testers.
Application development is performed in short sprints so that enough code is always in a deployable state.
A software development company specializes in being able to use whatever software development method their customer wants to use. One customer company wants to use the Waterfall method. What is a characteristic of this method?
a process that amplifies learning as well as delivers as quickly as possible
a software development process where the highest priority is to satisfy the customer through early and continuous delivery of valuable software
a software development process where a particular phase depends on the results of the previous phase
a process that eliminates anything that does not add value to the project including meetings and documentation
A software development company specializes in being able to use whatever software development method their customer wants to use. One customer company wants to use the Waterfall method. What is a characteristic of this method?
A software development process that prioritizes responding to change over following a plan
A process that eliminates inefficient ways of working like expecting coders to multitask
A software development process that focuses on frequent delivery of working software as well as collaboration between developers and business employees
A software devilment process that can only go forward.
A software development company specializes in being able to use whatever software development method their customer wants to use. One customer company wants to use the Waterfall method. What is a characteristic of this method?
a software development process that has the results of one phase feed into the next phase
a process that eliminates anything that does not add value to the project including meetings and documentation
a software development process that focuses on frequent delivery of working software as well as collaboration between developers and business employees
a process that eliminates inefficient ways of working like expecting coders to multitask
In which SDLC phase is the software product installed into the production environment to decide if it is ready for release?
implementation
deployment
design
testing
Which convention is used in Python to indicate that methods and variables in a class are private and not to be used outside of the class?
by using a single preceding underscore ( _ ) for a method or variable
by using the command class private classname() : to start the class definition
by using two preceding hyphens ( — ) for a method or variable
by declaring a private method or variable in the beginning of the class definition
A packet is received by a server. The packet has a destination port number of 80. What protocol or service is requested?
DHCP
Telnet over SSH
HTTP
RESTCONF

Which type of request is used to send a message to a Webex Teams space using Python and the Messages API?

A network administrator is assigned the 172.16.0.0/24 block of addresses to use in designing an IP addressing scheme. The administrator submits this design for approval:
172.16.0.0/26
172.16.0.64/27
172.16.0.96/26
172.16.0.128/27
What should be the response from the senior network engineer regarding this design?
This design is flawed because the 172.16.0.128/27 network number is invalid.
This design will work for the branch office.
This design is flawed because no design could have two networks that use a /26 mask and are not consecutive blocks of addresses.
This design is flawed because the 172.16.0.96/26 network is not a valid block of addresses.
This design is flawed because the 172.16.0.96/26 network overlaps with other addresses.
Which statement describes a stateful firewall?
It can filter packets based on information at Layers 3, 4, 5 and 7 of the OSI reference model.
It can determine if the connection is in the initiation, data transfer, or termination phase.
It can only filter packets based on limited Layer 3 and 4 information.
It can expand the number of IP addresses available and can hide network addressing design.

a software development process that focuses on frequent delivery of working software as well as collaboration between developers and business employees
a software development process that has the results of one phase feed into the next phase
a software development process that can only go forward
