Cisco CCST-Networking Exam Syllabus Topics:

Topic
Details

Topic 1

Standards and Concepts: The Cisco CCST-Networking exam assesses network technicians' knowledge of essential networking concepts, including identifying network building blocks, differentiating bandwidth from throughput, distinguishing various network types (LAN, WAN, MAN, CAN, PAN, WLAN), and comparing cloud versus on-premises services. It also measures understanding of common network applications and protocols.

Topic 2

Addressing and Subnet Formats: For aspiring Cisco network technicians, the CCST Networking exam evaluates the ability to compare private and public IP addresses, identify IPv4 addresses and subnet formats, and recognize IPv6 addresses and prefix formats. This ensures they can manage and configure network addressing effectively.

Topic 3

Security: Aspiring Cisco Network technicians taking the CCST-Networking Exam need to describe firewall operations, foundational security concepts, and configure basic wireless security on home routers (WPAx). This ensures they can implement and understand essential security measures within a network.

Cisco Certified Support Technician (CCST) NetworkingExam Sample Questions (Q24-Q29):

NEW QUESTION # 24
Which wireless security option uses a pre-shared key to authenticate clients?

A. 802.1x
B. WPA2-Personal
C. 802.1q
D. WPA2-Enterprise

Answer: B

Explanation:
WPA2-Personal, also known as WPA2-PSK (Pre-Shared Key), is the wireless security option that uses a pre-shared key to authenticate clients. This method is designed for home and small office networks and doesn't require an authentication server. Instead, every user on the network uses the same key or passphrase to connect1.

*What is a Wi-Fi Protected Access Pre-Shared Key (WPA-PSK)?
*Exploring WPA-PSK and WiFi Security
*WPA2-Personal: This wireless security option uses a pre-shared key (PSK) for authentication. Each client that connects to the network must use this key to gain access. It is designed for home and small office networks where simplicity and ease of use are important.
*WPA2-Enterprise: Unlike WPA2-Personal, WPA2-Enterprise uses 802.1x authentication with an authentication server (such as RADIUS) and does not rely on a pre-shared key.
*802.1x: This is a network access control protocol for LANs, particularly wireless LANs. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
*802.1q: This is a networking standard that supports VLAN tagging on Ethernet networks and is not related to wireless security.

* single building or home.
* MAN (Metropolitan Area Network): Covers a larger geographical area than a LAN, typically a city or campus.
* PAN (Personal Area Network): Connects devices within the range of an individual person, such as connecting a phone to a Bluetooth headset.
* WAN (Wide Area Network): Spans large geographical areas, connecting multiple LANs across cities, countries, or continents.

Answer:

Explanation:

Explanation:
* Three virtual machines are connected by a virtual network in the cloud.
* Model: IaaS (Infrastructure as a Service)
* Explanation: IaaS provides virtualized computing resources over the internet, including virtual machines, storage, and networks.
* Users access a web-based graphics design application in the cloud for a monthly fee.
* Model: SaaS (Software as a Service)
* Explanation: SaaS delivers software applications over the internet, typically on a subscription basis, accessible via a web browser.
* A company develops applications using cloud-based resources and tools.
* Model: PaaS (Platform as a Service)
* Explanation: PaaS provides a platform allowing customers to develop, run, and manage applications without dealing with the infrastructure.
* IaaS (Infrastructure as a Service): Provides virtualized hardware resources that customers can use to build their own computing environments.
* PaaS (Platform as a Service): Offers a platform with tools and services to develop, test, and deploy applications.
* SaaS (Software as a Service): Delivers fully functional applications over the internet that users can access and use without managing the underlying infrastructure.

NEW QUESTION # 27
Which address is included in the 192.168.200.0/24 network?

A. 192.168.200.13
B. 192.168.201.13
C. 192.168.199.13
D. 192.168.1.13

Answer: A

Explanation:
*192.168.200.0/24 Network: This subnet includes all addresses from 192.168.200.0 to 192.168.200.255. The
/24 indicates a subnet mask of 255.255.255.0, which allows for 256 addresses.
*192.168.199.13: This address is in the 192.168.199.0/24 subnet, not the 192.168.200.0/24 subnet.
*192.168.200.13: This address is within the 192.168.200.0/24 subnet.
*192.168.201.13: This address is in the 192.168.201.0/24 subnet, not the 192.168.200.0/24 subnet.
*192.168.1.13: This address is in the 192.168.1.0/24 subnet, not the 192.168.200.0/24 subnet.

NEW QUESTION # 28
In the network shown in the following graphic, Switch1 is a Layer 2 switch.

PC-A sends a frame to PC-C. Switch1 does not have a mapping entry for the MAC address of PC-C. Which action does Switch1 take?

A. Switch1 sends an ARP request to obtain the MAC address of PC-C.
B. Switch1 floods the frame out all active ports except port G0/1.
C. Switch1 drops the frame and sends an error message back to PC-A.
D. Switch1 queries Switch2 for the MAC address of PC-C.

Answer: B

Explanation:
Understanding How Layer 2 Switches Handle Unknown MAC Addresses
Switches operate atLayer 2 (Data Link Layer)of the OSI model and maintain aMAC address table (CAM table)to forward frames efficiently.
* When a switch receives a frame, itchecks its MAC address tableto see if it knows the destination MAC address.
* If the destinationMAC address is not in the table(meaning the switch does not know which port leads to PC-C), the switch follows theflooding behavior.
What Happens When Switch1 Receives a Frame from PC-A to PC-C?
* Switch1 checks its MAC table:
* The source MAC (PC-A) is recorded in the table on portG0/1.
* The destination MAC (PC-C)is not in the table.
* Switch1 does not know where PC-C is:
* Itfloodsthe frame out of allactive ports except the port it was received on (G0/1).
* This means the frame is sent to:
* Switch2 (via G0/23)
* PC-B (via G0/2)
* Switch2 receives the frame and follows the same process:
* If Switch2 has PC-C's MAC in its table, it forwards the frame appropriately.
* If not,it floodsthe frame again until PC-C replies.
* Once PC-C responds, Switch1 and Switch2 learn its MAC address and update their tables.
Why Other Options Are Incorrect:
#A. Switch1 queries Switch2 for the MAC address of PC-C.
* Incorrect:Switches do not query other switches directly for MAC addresses. Instead, they rely on learning MAC addresses dynamically through frame forwarding.
#B. Switch1 drops the frame and sends an error message back to PC-A.
* Incorrect:Switchesdo not drop frames for unknown MAC addresses. Instead, theyfloodthe frames out all ports except the incoming port.
#D. Switch1 sends an ARP request to obtain the MAC address of PC-C.
* Incorrect:
* ARP (Address Resolution Protocol)is only used to resolve IP addresses to MAC addresses.
* Since PC-A issending a frame (Layer 2), not an IP packet (Layer 3), ARP isnot involvedhere.
Conclusion
Since Switch1does not know the destination MAC address, itfloods the frame out all active ports except the port it was received on. This is the default behavior of Layer 2 switches when they encounter an unknown MAC address.
Thus, thecorrect answer is:#C. Switch1 floods the frame out all active ports except port G0/1.
