Real Question from LPIC-1 102-500

What is true about the Hop Limit field in the IPv6 header?

A. The field is not changed during the transport of a package.
B. The field is transmitted within a hop-by-hop extension header.
C. Each router forwarding the packet increases the field's value.
D. Each router forwarding the packet decreases the field's value.
E. For multicast packages, the field's value is always 1.

Answer below 👇

D. Each router forwarding the packet decreases the field's value.

In IPv6, the Hop Limit field serves the same purpose as the Time To Live (TTL) field in IPv4. Each time a router forwards the packet, it decrements the Hop Limit by 1. If the value reaches zero, the packet is discarded to prevent infinite loops in the network.

Real Question from LPIC-1 101-500

Which is the default percentage of reserved space for the root user on new ext4 filesystems?

A. 10%
B. 3%
C. 15%
D. 0%
E. 5%

Answer below 👇

[DailyDebian @daily_debian]

Correct Answer: E. 5%

Explanation: By default, new ext4 filesystems reserve 5% of the total space for the root user. This reserved space helps prevent system failures by allowing essential processes to function even when the filesystem is nearly full.

Real Question from CCNA 200-301

What is a benefit of using a Cisco Wireless LAN Controller?

A. It eliminates the need to configure each access point individually.
B. Central AP management requires more complex configurations.
C. Unique SSIDs cannot use the same authentication method.
D. It supports autonomous and lightweight APs.

Answer below 👇

[DailyDebian @daily_debian]

The correct answer is:

A. It eliminates the need to configure each access point individually.

A Cisco Wireless LAN Controller (WLC) allows centralized management of all connected lightweight access points. Instead of configuring each AP manually, you configure them from the controller, which simplifies deployment and maintenance across the wireless network.

Real Question from CCNA 200-301

Which IPv6 address block sends packets to a group address rather than a single address?

A. 2000::/3
B. FC00::/7
C. FE80::/10
D. FF00::/8

Answer below 👇

[DailyDebian @daily_debian]

The correct answer is:

D. FF00::/8
The FF00::/8 block is reserved for multicast addresses in IPv6. Multicast sends packets to multiple destinations in a group, not just a single address. Devices that are members of the multicast group receive the packets.

Real Question from CCNA 200-301

Which IPv6 address type provides communication between subnets and cannot route on the Internet?

A. link-local
B. unique local
C. multicast
D. global unicast

Answer below 👇

[DailyDebian @daily_debian]

The correct answer is:
B. unique local
Unique local addresses (ULA) in IPv6 are designed for communication within a site or between internal subnets but are not routable on the public Internet. They are similar to private IPv4 addresses (like 192.168.x.x). The prefix for ULA is fc00::/7.

Real Question from CompTIA SecAI+ CY0-001

An organization recently created a custom model that integrates with a language model (LLM). The developer notices that the application programming interface (API) costs have increased.

Which of the following is the best control to reduce cost?

A. Implementing prompt templates
B. Increasing central processing unit (CPU) and memory
C. Reducing the model size
D. Adjusting token limits

Answer below 👇

[DailyDebian @daily_debian]

Correct Answer:

D. Adjusting token limits. API costs for LLMs are primarily based on the number of tokens processed (input + output). Reducing token limits directly lowers usage and therefore cost, making it the most effective control.

Real Question from CompTIA SecAI+ CY0-001

A security operations center (SOC) has a very high volume of logs and alerts. The manager proposes implementing a machine learning (ML) system to help with triage. Which of the following tasks is most suitable?

A. Applying filters to specific alerts
B. Automatically patching vulnerable systems
C. Identifying and classifying alerts
D. Summarizing the content of alerts

Answer below 👇

[DailyDebian @daily_debian]

Correct Answer:

C. Identifying and classifying alerts. Machine learning is well suited for analyzing large volumes of SOC data to detect patterns, group similar alerts, and prioritize them. This directly supports triage by helping analysts focus on the most relevant or high-risk alerts.
