How is the chip-level security of an IoT device achieved?
- A. By changing the password of the router
- B. By turning off the device when not needed or not in use
- C. By encrypting the JTAG interface
- D. By closing insecure network services
Answer: C
Explanation:
Chip-level security for an IoT device is achieved by implementing measures that protect the device's hardware, particularly against physical attacks and unauthorized access to debugging ports. Encrypting the JTAG (Joint Test Action Group) interface is a critical step in securing an IoT device at the chip level. The JTAG interface is a standard for testing PCBs (Printed Circuit Boards) and widely used for debugging embedded systems. If left unsecured, it can be exploited to reverse engineer the device firmware or to inject malicious code. Encryption of the JTAG interface ensures that even if attackers gain physical access to the JTAG port, they cannot use it to compromise the device without the encryption key.

Which of the following types of transmission is the process of sending one bit at a time over a single
transmission line?
- A. Serial data transmission
- B. Multicast transmission
- C. Unicast transmission
- D. Parallel data transmission
Answer: A
Explanation:
In serial data transmission, one bit is sent after another (bit-serial) on a single transmission line. It is the
simplest method of transmitting digital information from one point to another. This transmission is suitable for
providing communication between two participants as well as for multiple participants. It is used for all long-
haul communication and provides high data rates. It is also inexpensive and beneficial in transferring data over
long distances.
Answer option D is incorrect. In parallel data transmission, several data signals are sent simultaneously over
several parallel channels. Parallel data transmission is faster than serial data transmission. It is used primarily
for transferring data between devices at the same site. For instance, communication between a computer and
printer is most often parallel, allowing the entire byte to be transferred in one operation.
Answer option A is incorrect. The unicast transmission method is used to establish communication between a
single host and a single receiver. Packets sent to a unicast address are delivered to the interface recognized
by that IP address, as shown in the following figure:
Answer option C is incorrect. The multicast transmission method is used to establish communication between
a single host and multiple receivers. Packets are sent to all interfaces recognized by that IP address, as shown
in the figure below:
NEW QUESTION # 64
Which of the following examines Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs) for a disaster recovery strategy?
- A. Business Continuity Plan
- B. Business Impact Analysis
- C. Risk Management
- D. Risk Assessment
Answer: B
Explanation:
Business Impact Analysis (BIA) is the process that determines the potential impacts of business function disruptions and gathers information needed to develop recovery strategies. A critical part of BIA is examining Recovery Point Objectives (RPOs) and Recovery Time Objectives (RTOs) for a disaster recovery strategy. RPOs define the maximum age of files that must be recovered from backup storage for normal operations to resume after a disaster, while RTOs specify the maximum amount of time that a resource can remain unavailable after a disaster.
NEW QUESTION # 65
Brendan wants to implement a hardware based RAID system in his network. He is thinking of choosing a suitable RAM type for the architectural setup in the system. The type he is interested in provides access times of up to 20 ns. Which type of RAM will he select for his RAID system?
- A. SRAM
- B. NAND flash memory
- C. NVRAM
- D. SDRAM
Answer: A
Explanation:
SRAM, or Static Random-Access Memory, is known for its low access time, typically around 20 ns, which makes it suitable for applications requiring high speed, such as cache memory in computers or, in this case, a RAID system. SRAM is faster than DRAM because it does not need to be refreshed as often, which is why it's used where speed is critical. Although SRAM is more expensive and has less density compared to other types of RAM, its speed advantage makes it the preferred choice for Brendan's RAID system requirements.

NEW QUESTION # 80
Mark is monitoring the network traffic on his organization's network. He wants to detect a TCP and UDP ping sweep on his network. Which type of filter will be used to detect this on the network?
- A. Tcp.srcport==7 and udp.srcport==7
- B. Tcp.dstport==7 and udp.srcport==7
- C. Tcp.dstport==7 and udp.dstport==7
- D. Tcp.srcport==7 and udp.dstport==7
Answer: C
Explanation:
To detect TCP and UDP ping sweeps on a network, the appropriate filter would be one that checks for packets directed at port 7, which is commonly used for the 'echo' service. This service is associated with ping functionality for both TCP and UDP protocols. Therefore, the correct filter to use would be Tcp.dstport==7 and udp.dstport==7, which checks for incoming packets where the destination port is 7 for both TCP and UDP traffic. This allows Mark to identify ping sweep attempts, as these would typically send packets to this port to elicit a response from the network.
References: The Certified Network Defender (CND) course material outlines the importance of understanding and utilizing network filters to detect various types of network scans and sweeps, including TCP and UDP ping sweeps1. This is further supported by industry practices and discussions on network security monitoring and defense1.
NEW QUESTION # 81
John works as an Incident manager for TechWorld Inc. His task is to set up a wireless network for his organization. For this, he needs to decide the appropriate devices and policies required to set up the network.
Which of the following phases of the incident handling process will help him accomplish the task?
- A. Recovery
- B. Eradication
- C. Containment
- D. Preparation
Answer: D
Explanation:
Preparation is the first step in the incident handling process. It includes processes like backing up copies of all key data on a regular basis, monitoring and updating software on a regular basis, and creating and implementing a documented security policy. To apply this step a documented security policy is formulated that outlines the responses to various incidents, as a reliable set of instructions during the time of an incident. The following list contains items that the incident handler should maintain in the preparation phase i.e. before an incident occurs:
Establish applicable policies
Build relationships with key players
Build response kit
Create incident checklists
Establish communication plan
Perform threat modeling
Build an incident response team
Practice the demo incidents
Answer option A is incorrect. The Containment phase of the Incident handling process is responsible for supporting and building up the incident combating process. It ensures the stability of the system and also confirms that the incident does not get any worse. The Containment phase includes the process of preventing further contamination of the system or network, and preserving the evidence of the contamination.
Answer option D is incorrect. The Eradication phase of the Incident handling process involves the cleaning-up of the identified harmful incidents from the system. It includes the analyzing of the information that has been gathered for determining how the attack was committed. To prevent the incident from happening again, it is vital to recognize how it was conceded out so that a prevention technique is applied.
Answer option B is incorrect. Recovery is the fifth step of the incident handling process. In this phase, the Incident Handler places the system back into the working environment. In the recovery phase the Incident Handler also works with the questions to validate that the system recovery is successful. This involves testing the system to make sure that all the processes and functions are working normal. The Incident Handler also monitors the system to make sure that the systems are not compromised again. It looks for additional signs of attack.
