CCNA Matching — 10 Questions

Question 1

Match each REST-style method to the most common intent.

Accepted Answer

GET - Retrieve a resource. RESTful methods map to CRUD operations: GET retrieves, POST creates, PUT replaces, PATCH partially updates, DELETE removes, and OPTIONS returns allowed methods.

Answer

GET - Create a new resource

Answer

POST - Retrieve a resource

Answer

PUT - Partially update a resource

Question 2

Match each network service to its primary function.

Accepted Answer

DNS: Translates domain names to IP addresses. Each network service has a distinct primary function: DNS translates names to IPs, DHCP automates IP assignment, NTP synchronizes time, SNMP manages devices, FTP transfers files, and HTTP serves web content.

Answer

DNS: Assigns IP addresses dynamically to devices on a network

Answer

DNS: Synchronizes time across network devices

Answer

DNS: Manages and monitors network devices

Question 3

Match each HTTP method to its common REST API action.

Accepted Answer

GET - Retrieve data. GET retrieves data; POST creates; PUT replaces; PATCH partially updates; DELETE removes; OPTIONS queries available methods.

Answer

GET - Create data

Answer

POST - Retrieve data

Answer

PUT - Partially update data

Question 4

Match each switching feature to its most accurate purpose.

Accepted Answer

STP prevents loops, VTP manages VLANs, EtherChannel aggregates links, Port Security restricts MAC addresses, DTP negotiates trunks, and Rapid PVST+ provides fast per-VLAN convergence.. Which accurately pairs each switching feature with its purpose: Spanning Tree Protocol (STP) prevents loops in a switched network by blocking redundant paths; VLAN Trunking Protocol (VTP) manages the addition, deletion, and renaming of VLANs across the network; EtherChannel aggregates multiple physical links into a single logical link for increased bandwidth and redundancy; Port Security limits the number of MAC addresses allowed on a switch port to prevent unauthorized access; Dynamic Trunking Protocol (DTP) automatically negotiates trunking between switches; and Rapid PVST+ provides fast convergence for each VLAN using multiple spanning tree instances. The other options contain incorrect pairings, such as mixing up STP with VLAN management or EtherChannel with loop prevention.

Answer

STP manages VLANs, VTP prevents loops, EtherChannel restricts MAC addresses, Port Security aggregates links, DTP provides fast per-VLAN convergence, and Rapid PVST+ negotiates trunks.

Answer

STP aggregates links, VTP prevents loops, EtherChannel manages VLANs, Port Security negotiates trunks, DTP restricts MAC addresses, and Rapid PVST+ provides fast per-VLAN convergence.

Answer

STP provides fast per-VLAN convergence, VTP aggregates links, EtherChannel prevents loops, Port Security manages VLANs, DTP restricts MAC addresses, and Rapid PVST+ negotiates trunks.

Question 5

Drag and drop the syslog severity levels on the left to their corresponding names and meanings on the right.

Accepted Answer

Level 0 – Emergency: System is unusable. All four options correctly match syslog severity levels 0-3 with their descriptions. Levels 0 (Emergency), 1 (Alert), 2 (Critical), and 3 (Error) are the highest severity levels.

Question 6

Drag and drop the items on the left to match the descriptions on the right.

Accepted Answer

Access port: Carries traffic for a single VLAN, configured with switchport mode access.. Access ports carry traffic for a single VLAN and are configured with switchport mode access. Voice VLANs are added to an access port with switchport voice vlan to separate voice and data traffic. Trunk ports carry multiple VLANs and are set with switchport mode trunk; allowed VLANs can be restricted with switchport trunk allowed vlan.

Answer

Voice VLAN: Added to a trunk port to prioritize voice traffic.

Answer

Allowed VLANs: Configured with switchport access vlan to restrict VLANs on a trunk.

Question 7

Drag and drop the route types on the left to the correct administrative distance and use case descriptions on the right.

Accepted Answer

Connected routes: AD 0, directly connected networks. All the given pairings are correct. Connected routes use AD 0 because they are directly connected. Static routes use AD 1 as they are manually configured. EIGRP internal routes have AD 90, and OSPF routes have AD 110; both are IGPs used for routing within the same autonomous system.

Question 8

Drag and drop the protocols/technologies on the left to the descriptions on the right.

Accepted Answer

SSH: Provides secure remote access to network devices using encryption, typically on TCP port 22.. SSH (Secure Shell) provides encrypted remote access to network devices, typically using TCP port 22. It is the secure alternative to Telnet. Telnet (port 23) is unencrypted and insecure. HTTP (port 80) is used for web traffic, not remote access. FTP (port 21) is for file transfers and is not designed for remote shell access. Therefore, only SSH matches the description of secure remote access.

Answer

Telnet: Provides secure remote access to network devices using encryption, typically on TCP port 23.

Answer

HTTP: Provides secure remote access to network devices using encryption, typically on TCP port 80.

Answer

FTP: Provides secure remote access to network devices using encryption, typically on TCP port 21.

Question 9

Drag and drop the items on the left to match the descriptions on the right.

Accepted Answer

switchport mode trunk: Configures a trunk port. VLANs segment a switch into multiple broadcast domains. 802.1Q trunking encapsulates frames with a VLAN tag, while the native VLAN carries untagged traffic. 'switchport mode trunk' configures a trunk port, 'show vlan brief' lists VLAN assignments, and inter-VLAN routing enables communication between VLANs typically using a router or Layer 3 switch.

Answer

VLAN: Encapsulates frames with a VLAN tag

Answer

802.1Q trunking: Carries untagged traffic on a trunk

Answer

Native VLAN: Segments a switch into multiple broadcast domains

Question 10

Drag and drop the protocol/model on the left to the correct description on the right.

Accepted Answer

YANG: Data modeling language used to define configuration and state data structures. YANG is a data modeling language used to define configuration and state data. NETCONF is an XML-based protocol over SSH that supports transactional configuration management. RESTCONF is a RESTful API over HTTPS that uses standard HTTP methods like GET, PUT, POST, DELETE. NETCONF <edit-config> is an operation that modifies configuration with options like merge, replace, create, delete. RESTCONF PATCH is an HTTP method used for partial updates to a resource.
