Soalan 10
Match each software concept to its purpose.
REST APIs use HTTP, JSON exchanges data, Git controls versions, and repositories store code.
Soalan 11
What does an HTTP GET request do?
GET retrieves resources without side effects. POST creates, DELETE removes, and PUT updates.
Soalan 12
What does an HTTP POST request do?
POST creates resources on a server. GET retrieves, DELETE removes, and PUT updates.
Soalan 13
What does an HTTP PUT request do?
PUT updates or replaces a resource. GET retrieves, DELETE removes, and logs record events.
Soalan 14
What does an HTTP DELETE request do?
DELETE removes a resource. POST creates, GET reads, and PUT updates.
Soalan 15
What does HTTP status code 200 mean?
200 means the request succeeded. 404 is not found, 500 is server error, and 401 is unauthorized.
Soalan 16
What does HTTP status code 404 mean?
404 means the requested resource was not found. 200 is OK, 201 is created, and 3xx redirects.
Soalan 17
What is an API key?
API keys identify clients making requests. Indexes, addresses, and firewall rules are different.
Soalan 18
What is OAuth 2.0?
OAuth 2.0 allows delegated authorization. Routing protocols, formats, and switch models are different.
Soalan 19
What is a webhook?
Webhooks push event notifications over HTTP. DNS records, cables, and backups are unrelated.
Soalan 20
Match each API concept to its purpose.
GET retrieves, POST creates, 404 is not found, and webhooks notify events.
Soalan 21
What is Ansible?
Ansible automates configuration and provisioning. Switches, databases, and firewalls are not automation tools.
Soalan 22
What is an Ansible playbook?
Playbooks define tasks in YAML. Routing tables, DNS zones, and VMs are different.
Soalan 23
What is Terraform?
Terraform manages infrastructure declaratively. Protocols, formats, and switches are different.
Soalan 24
What is an Ansible module?
Modules are reusable automation units. Cables, volumes, and DNS records are not modules.
Soalan 25
What is idempotency in automation?
Idempotent operations can be repeated without harmful changes. Encryption, scaling, and routing are different.
Soalan 26
What is the Cisco DNA Center API?
DNA Center exposes APIs for network management and automation. Protocols, storage, and DNS are different.
Soalan 27
What is the Meraki API?
Meraki APIs manage cloud networks. Switch models, formats, and firewall rules are different.
Soalan 28
What is a controller in networking?
Controllers centralize network management. Cables, subnets, and DNS records are different.
Soalan 29
What is intent-based networking?
Intent-based networking translates business intent into network policy. Manual config, static routes only, and no automation are not intent-based.
Soalan 30
Match each automation platform to its purpose.
Ansible automates config, Terraform manages infrastructure, DNA Center manages campus networks, and Meraki manages cloud networks.
Soalan 31
What is an IP address?
IP addresses identify devices at Layer 3. MAC addresses are hardware, and passwords or cables are different.
Soalan 32
What is a MAC address?
MAC addresses are burned into interfaces. IP addresses are logical, and DNS records or firewalls are different.
Soalan 33
What is a switch used for?
Switches connect LAN devices and forward frames. Routers connect networks, DNS resolves names, and encryption protects data.
Soalan 34
What is a router used for?
Routers forward packets between networks. Switches connect LANs, and storage or printing are unrelated.
Soalan 35
What is a VLAN?
VLANs segment traffic logically. Cables, DNS zones, and firewalls are different.
Soalan 36
What is a subnet?
Subnets divide IP ranges. Ports, DNS records, and backups are different.
Soalan 37
What is DNS used for?
DNS translates names to addresses. DHCP assigns addresses, firewalls filter, and encryption protects.
Soalan 38
What is DHCP used for?
DHCP assigns IP configuration to clients. DNS resolves names, routers forward, and firewalls filter.
Soalan 39
What is a firewall used for?
Firewalls permit or block traffic. DNS resolves, DHCP assigns, and storage stores.
Soalan 40
Match each network concept to its purpose.
