Oracle Cloud Infrastructure 2024 Networking Professional Sample Questions (Q30-Q35):

NEW QUESTION # 30
You need to assign a static public IP address to a specific instance. What service do you use?

  • A. NAT Gateway
  • B. Public IP Pool
  • C. Internet Gateway
  • D. Service Gateway

Answer: B

Explanation:
Internet Gateway: This service allows communication between your VCN and the internet, but it doesn,t assign IP addresses to instances.
Service Gateway: This facilitates private access to Oracle services, not individual instance public IP assignment.
NAT Gateway: This translates private IP addresses of instances to a single public IP address, not providing dedicated IPs for specific instances.
Public IP Pool: This service holds a pool of reserved public IP addresses. You can create a reserved public IP from this pool and attach it to a specific VNIC associated with your instance, effectively assigning it a static public IP address.


NEW QUESTION # 31
When configuring a bastion service in OCI, which of the following security measures is MOST important to implement?

  • A. Restricting inbound traffic to bastion hosts only from specific IP addresses.
  • B. Disabling SSH access on bastion hosts and using alternative protocols like RDP.
  • C. Configuring bastion hosts with static IP addresses for easy access management.
  • D. Allowing password-based authentication for convenience alongside other security measures.

Answer: A

Explanation:
Here,s why:
A). Restricting Inbound Traffic:This significantly reduces the attack surface by limiting potential access points to a narrow set of authorized sources. Even if an attacker compromises a system with allowed access, they,re less likely to be able to exploit the bastion due to the restricted traffic flow.
This adheres to the principle of least privilege by granting access only to those who genuinely need it, minimizing potential vulnerabilities.
B). Disabling SSH and Using Alternative Protocols:While disabling SSH completely might seem secure, it might restrict legitimate access and require alternative solutions that may not be readily available or offer the same level of security. Evaluating alternative protocols like RDP with strong authentication measures can be considered, but the focus should still be on controlling access, not eliminating protocols entirely.
C). Static IP Addresses:While convenient for management, static IP addresses can make them easier to target for attackers. Dynamic IP allocation with proper management practices can enhance security without sacrificing usability.
D). Password-Based Authentication:This is generally considered less secure than other methods like multi-factor authentication (MFA), which adds an extra layer of verification beyond just a password. Password-based access should be avoided if possible, or only used with very strong password policies and frequent rotations.
Therefore, while all security measures have their roles, restricting inbound traffic holds the highest priority in securing a bastion service. It directly addresses the core purpose of a bastion - acting as a controlled entry point - and significantly reduces the potential for unauthorized access.


NEW QUESTION # 32
Which of the following statements about route advertisement across DRGs is TRUE?

  • A. Route advertisement across DRGs is not possible, and each DRG must have its own set of static routes.
  • B. All routes learned from a DRG are automatically advertised to all other attached DRGs.
  • C. You can configure filters to control which routes are advertised across DRGs, based on prefixes or other criteria.
  • D. DRGs automatically learn and advertise routes from attached VCNs, eliminating the need for route tables in VCNs.

Answer: C

Explanation:
A). All routes learned from a DRG are automatically advertised to all other attached DRGs: This is false. Route advertisement across DRGs is controlled and requires configuration using route filters. Advertising all routes without filtering can lead to routing loops and unintended traffic flow.C. DRGs automatically learn and advertise routes from attached VCNs, eliminating the need for route tables in VCNs: This is partly true. DRGs do import routes from attached VCNs by default, but route tables are still essential in VCNs to manage internal routing within the VCN and control what specific routes get exported to the DRG for further advertisement.D. Route advertisement across DRGs is not possible, and each DRG must have its own set of static routes: This is false. Route advertisement across DRGs is a core functionality, allowing for efficient routing between VCNs across different regions or connected networks. Static routes can be used within DRGs, but relying solely on them can be inflexible and impractical for larger-scale or dynamic network environments.


NEW QUESTION # 33
How can you reserve a block of public IP addresses for future use?

  • A. Enable public IP auto-assignment for your VNICs.
  • B. Configure a NAT Gateway with additional public IP addresses.
  • C. Create a new subnet with a larger CIDR block.
  • D. Allocate public IPs from a Public IP Pool and set them to "Reserved".

Answer: D

Explanation:
A). Create a new subnet with a larger CIDR block: This increases the pool of private IP addresses available within the subnet, but it doesn,t reserve specific public IPs for future use.B. Enable public IP auto-assignment for your VNICs: This automatically assigns dynamic public IPs to your instances, which is the opposite of reserving them.C. Configure a NAT Gateway with additional public IP addresses: This allows multiple instances to share a single public IP for outbound traffic, but it doesn,t reserve specific IPs for future use.Reserving public IP addresses from a Public IP Pool is the most common way to ensure specific IP addresses are available for future use. Most cloud providers offer this functionality, and the specific steps may vary slightly depending on the provider. However, the general process typically involves:
Accessing the Public IP Pool management interface: This is usually found within the networking section of your cloud provider,s console or API.
Selecting the desired number of IP addresses: Specify the number of public IPs you want to reserve.
Choosing a specific IP range (optional): In some cases, you may be able to choose a specific range of IP addresses from within the available pool.
Setting the IP addresses to "Reserved": This marks the selected IPs as unavailable for automatic assignment and ensures they are kept for your future use.


NEW QUESTION # 34
What is the primary function of dedicated endpoints in OCI?

  • A. To provide secure, tenancy-specific access to resources.
  • B. None of the above.
  • C. To increase data transfer speeds.
  • D. To provide a shared endpoint for all OCI customers.

Answer: A

Explanation:
The primary function of dedicated endpoints in OCI is to provide secure, tenancy-specific access to resources.
Here,s why the other options are not correct:
A). To provide a shared endpoint for all OCI customers: This is incorrect. Dedicated endpoints are unique to each individual tenant, offering isolation and enhanced security.C. To increase data transfer speeds: While dedicated endpoints might indirectly improve performance due to potential security optimizations, their primary function is not focused on raw speed increases.D. None of the above: As explained earlier, dedicated endpoints are crucial for secure access within OCI.By offering unique and immutable endpoints for each tenant, dedicated endpoints significantly enhance security by:
Preventing accidental or malicious access: Each tenant,s resources are isolated, minimizing the impact of security incidents.
Reducing the attack surface: By eliminating shared endpoints, attackers have fewer potential targets to exploit.
Supporting stricter security policies: Organizations with stringent security requirements can leverage dedicated endpoints to meet their compliance needs.
