CCNA 200-301 OBJECTIVES EXAM
QUESTIONS WITH CORRECT ANSWERS
1.1a What is the role and function of a Router? - Correct Answers -- Determines the
best path to available networks
- Forwards actual production traffic to those networks
1.1b What is the role and function of L2 switches - Correct Answers -ex> Bridges,
Modems, Network cards, 2-layer switches.
ROLE:
- Performs switching and forwarding of information and uses the mac addresses table
to make the forwarding decisions. The unit of data at this stage is called FRAMES, so
frames are transmitted at this level.
FUNCTION:
- Learning MAC addresses
- Filtering and forwarding frames
- Preventing loops on the network
1.1b What is the role and function of L3 switches - Correct Answers -ROLE:
- They are like L2 switches, but L3 switches can perform as routers. (Multiple Ethernet
ports)
FUNCTION:
- able to segregate ports into separate VLANs and perform the routing between them, a
function which a layer 2 switch cannot perform.
- forwarding is performed by specialized hardware called ASICs (Application Specific
Integrated Circuit)
- can only perform routing on ethernet ports
1.1c What is the role and function of NGFW (Next-Gen Firewalls) ? - Correct Answers -
NGFW requirements:
- Standard firewall capabilities such as stateful inspection
-An integrated IPS
-Application-level inspection (to block malicious or risky apps)
, - The ability to leverage external security intelligence to address evolving security
threats.
ROLE:
- It is a network security device that monitors incoming and outgoing network traffic. It
allows/blocks traffic by performing simple packet filtering and stateful inspection based
on ports and protocols.
FUNCTION:
- In addition to providing standard firewall functionality, can also block threats such as
advanced malware and application-layer attacks
1.1c What is the role and function of IPS (Intrusion Prevention System) ? - Correct
Answers -ROLE:
- An intrusion prevention system (IPS) provides real-time detection and blocking of
attacks.
1.1d What is the role and function of Access Point Devices? - Correct Answers -ROLE:
- An access point is a device, such as a wireless router, that allows wireless devices to
connect to a network.
FUNCTION:
- They have at least two network interfaces: a wireless interface that understands the
details of 802.11 and a second interface to connect to wired networks.
1.1e What is the role and function of Controllers? (Cisco DNA Center)? - Correct
Answers -ROLE:
- The controller in a network that uses Cisco SDA (Cisco DNA centre and SDA are
associated closely in the context of network automation)
- The controller in a non-SDA network management platform for traditional network
devices.
FUNCTION:
- Provides a centralized management platform for complete management and control
over the enterprise network.
- It is a software-based application that is installed in centralized Cisco DNA appliances
to manage the whole network from a single place.
1.1e What is the role and function of Controllers? (WLC)? - Correct Answers -ROLE:
- The device or the software loaded on the server that manages and controls the
wireless access points and the wireless device, thereby ensuring the seamless
connectivity when you move from one floor to the other floor of the office building.
FUNCTION:
