質問 # 10
Which protocol is used by both internet service providers (ISPs) and network service providers (NSPs)?
- A. Border Gateway Protocol (BGP)
- B. Split horizon
- C. Routing Information Protocol (RIP)
- D. Open Shortest Path First (OSPF)
正解：A
解説：
Border Gateway Protocol (BGP) is a protocol that enables ISPs and NSPs to exchange routing information among themselves. BGP is used to determine the best path for sending data packets across the Internet. BGP is also known as the protocol of the Internet backbone, as it connects different autonomous systems (ASes) that form the Internet. BGP is not used by end systems or local networks, but only by routers that operate at the border of ASes. BGP is a complex and dynamic protocol that can handle changes in network topology, traffic load, and policy requirements. BGP is also a scalable protocol that can support the growth of the Internet1234 Reference:

正解：D
質問 # 12
What is a characteristic of the National Institute Standards and Technology (NIST) defined cloud computing model?
- A. defines any network service
- B. enables on-demand network services
- C. requires the use of two or more cloud service providers
- D. requires the use of only one cloud service provider
正解：B
解説：
According to the NIST definition, cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction1. One of the essential characteristics of cloud computing is on-demand self-service, which means that users can request and obtain computing resources as needed, without requiring human intervention from the service provider2. On-demand network services are an example of this characteristic, as they allow users to access network resources such as bandwidth, routing, firewall, or load balancing, on demand and in a scalable manner3.

- A. exploitation
- B. delivery
- C. reconnaissance
- D. weaponization
正解：D
解説：
"Weaponization: Next, attackers determine which methods to use to compromise a target endpoint. They may choose to embed intruder code within seemingly innocuous files such as a PDF or Microsoft Word document or email message."
質問 # 14
What are two disadvantages of Static Rout ng? (Choose two.)
- A. Requirement for additional computational resources
- B. Single point of failure
- C. Manual reconfiguration
- D. Less security
正解：B、C
解説：
Static routing is a form of routing that occurs when a router uses a manually-configured routing entry, rather than information from dynamic routing traffic 1. Static routing has some advantages, such as simplicity, low overhead, and full control, but it also has some disadvantages, such as:
* Manual reconfiguration: Static routes require manual effort to configure and maintain. This can be time-consuming and error-prone, especially in large networks with many routes. If there is a change in the network topology or a link failure, the static routes need to be updated manually by the network administrator 23.
* Single point of failure: Static routing is not fault tolerant. This means that if the path used by the static route stops working, the traffic will not be rerouted automatically. The network will be unreachable until the failure is repaired or the static route is changed manually. Dynamic routing, on the other hand, can adapt to network changes and find alternative paths 23.
質問 # 15
Which technique changes protocols at random during a session?
- A. hiding within SSL encryption
- B. port hopping
- C. use of non-standard ports
- D. tunneling within commonly used services
正解：B
解説：
Port hopping is a technique that changes protocols at random during a session to evade detection and analysis by security devices. Port hopping can be used by malware or attackers to communicate with command and control servers or to exfiltrate data. Port hopping makes it difficult to identify and block malicious traffic based on port numbers or signatures.

質問 # 16
What does SOAR technology use to automate and coordinate workflows?
- A. Security Incident and Event Management
- B. algorithms
- C. playbooks
- D. Cloud Access Security Broker
正解：C
解説：
Explanation
SOAR tools ingest aggregated alerts from detection sources (such as SIEMs, network security tools, and mailboxes) before executing automatable, process-driven playbooks to enrich and respond to these alerts.
質問 # 17
Which endpoint product from Palo Alto Networks can help with SOC visibility?
- A. AutoFocus
- B. Cortex XDR
- C. WildFire
- D. STIX
正解：B
質問 # 18
Which classification of IDS/IPS uses a database of known vulnerabilities and attack profiles to identify intrusion attempts?
- A. Knowledge-based
- B. Statistical-based
- C. Behavior-based
- D. Anomaly-based
正解：A
解説：
A knowledge-based system uses a database of known vulnerabilities and attack profiles to identify intrusion attempts. These types of systems have lower false-alarm rates than behavior-based systems but must be continually updated with new attack signatures to be effective.
* A behavior-based system uses a baseline of normal network activity to identify unusual patterns or levels of network activity that may be indicative of an intrusion attempt.
These types of systems are more adaptive than knowledge-based systems and therefore may be more effective in detecting previously unknown vulnerabilities and attacks, but they have a much higher false-positive rate than knowledge-based systems.
質問 # 19
On an endpoint, which method is used to protect proprietary data stored on a laptop that has been stolen?
- A. endpoint-based firewall
- B. periodic data backups
- C. operating system patches
- D. full-disk encryption
正解：D
解説：
Full-disk encryption is a method of protecting data on a laptop that has been stolen by encrypting the entire hard drive, making it unreadable without the correct password or key. This prevents unauthorized access to the proprietary data stored on the laptop, even if the thief removes the hard drive and connects it to another device. Full-disk encryption can be enabled using built-in features such as BitLocker on Windows or FileVault on macOS, or using third-party software such as Absolute Home & Office12.

質問 # 20
A user is given access to a service that gives them access to cloud-hosted physical and virtual servers, storage, and networking.
Which NIST cloud service model is this?
- A. SaaS
- B. IaaS
- C. CaaS
- D. PaaS
正解：B
解説：
According to the NIST definition of cloud computing, Infrastructure as a Service (IaaS) is a cloud service model that provides "the capability to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications" 1. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, and deployed applications; and possibly limited control of select networking components (e.g., host firewalls) 1. In other words, IaaS gives the user access to cloud-hosted physical and virtual servers, storage, and networking, as stated in the question. Reference: 1: SP 800-145, The NIST Definition of Cloud Computing | CSRC 2
質問 # 21
Which technique changes protocols at random during a session?
- A. hiding within SSL encryption
- B. port hopping
- C. use of non-standard ports
- D. tunneling within commonly used services
正解：B
解説：
Port hopping, in which ports and protocols are randomly changed during a session.
質問 # 22
In an IDS/IPS, which type of alarm occurs when legitimate traffic is improperly identified as malicious traffic?
- A. True-negative
- B. True-positive
- C. False-positive
- D. False-negative
正解：C
解説：
Explanation
In anti-malware, a false positive incorrectly identifies a legitimate file or application as malware. A false negative incorrectly identifies malware as a legitimate file or application. In intrusion detection, a false positive incorrectly identifies legitimate traffic as a threat, and a false negative incorrectly identifies a threat as legitimate traffic.
質問 # 23

- A. containers and developers
- B. infrastructure and containers
- C. connectors and interfaces
- D. data center and UPS
正解：C
質問 # 24
A doctor receives an email about her upcoming holiday in France. When she clicks the URL website link in the email, the connection is blocked by her office firewall because it's a known malware website. Which type of attack includes a link to a malware website in an email?
- A. pharming
- B. whaling
- C. spam
- D. phishing
正解：D
解説：
Phishing is a type of attack that involves sending fraudulent emails that appear to be from legitimate sources, such as banks, companies, or individuals, in order to trick recipients into clicking on malicious links, opening malicious attachments, or providing sensitive information12. The link to a malware website in the email is an example of a malicious link, which may lead to the installation of malware, ransomware, spyware, or other malicious software on the user's device, or the redirection to a fake website that mimics a legitimate one, where the user may be asked to enter their credentials, personal information, or financial details34. Phishing emails often use social engineering techniques, such as creating a sense of urgency, curiosity, or fear, to persuade the user to click on the link or attachment, or to reply to the email5. Phishing emails may also spoof the sender's address, domain, or logo, to make them look more authentic and trustworthy6.
Whaling, pharming, and spam are not the correct answers for this question. Whaling is a specific type of phishing that targets high-profile individuals, such as executives, celebrities, or politicians, with the aim of stealing their confidential information or influencing their decisions7. Pharming is a type of attack that involves redirecting the user's web browser to a fake website, even if they enter the correct URL, by modifying the DNS server or the user's hosts file. Spam is the unsolicited or unwanted electronic messages, such as emails, texts, or instant messages, that are sent in bulk to a large number of recipients, usually for advertising, marketing, or scamming purposes.
