Question # 1 A systems administrator wants to verify the word "qwerty" has not been used as a password on any of the administrative web consoles in a network. Which of the following will achieve this goal?
A. A service availability scanB. An agent-based vulnerability scanC. A default and common credentialed scanD. A network port scan
Click for Answer
C. A default and common credentialed scan
Answer Description Explanation:
A default and common credentialed scan is what the administrator should use to verify the word “qwerty” has not been used as a password on any of the administrative web consoles in a network. A credentialed scan is a type of vulnerability scan that uses valid credentials or accounts to access and scan target systems or devices. A credentialed scan can provide more accurate and detailed results than a non-credentialed scan, as it can perform more actions and tests on target systems or devices. A default and common credentialed scan is a type of credentialed scan that uses default or common credentials or accounts, such as admin/admin, root/root, etc., to access and scan target systems or devices. A default and common credentialed scan can help to identify weak or insecure passwords on administrative web consoles, such as “qwerty”, and recommend stronger passwords.
Question # 2 A cloud administrator is reviewing the annual contracts for all hosted solutions. Upon review of the contract for the hosted mail solution, the administrator notes the monthly subscription rate has increased every year. The provider has been in place for ten years, and there is a large amount of data being hosted. Which of the following is a barrier to switching providers? A. Service_level agreement
B. Vendor lock-in
C. Memorandum of understanding
D. Encrypted data
Click for Answer
B. Vendor lock-in
Answer Description Explanation :
The correct answer is B. Vendor lock-in. Vendor lock-in is a situation where a customer becomes dependent on a certain cloud provider and cannot easily switch to another provider without significant costs or disruptions. This can happen when the customer uses features or services that are only available from that specific provider, or when the customer has a large amount of data stored with the provider that is difficult to migrate. According to the web search results, vendor lock-in is a common concern in cloud computing1234. A service level agreement, a memorandum of understanding, and encrypted data are not barriers to switching providers, as they do not create a dependency on a specific provider or make it difficult to move data. For more information on vendor lock-in and how to avoid it, you can refer to the Cloudflare website1 or the Seagate blog4.
Question # 3 A systems administrator needs to migrate email services to the cloud model that requires the least amount of administrative effort. Which of the following should the administrator select? A. DBaaSB. SaaSC. IaaSD. PaaS
Click for Answer
B. SaaS
Answer Description Explanation :
The cloud model that requires the least amount of administrative effort to migrate email services is software as a service (SaaS). SaaS is a cloud model that provides applications or software that are hosted and managed by a cloud provider and delivered to users over the internet. SaaS eliminates the need for installing, configuring, updating, or maintaining the software or its underlying infrastructure, as these tasks are handled by the cloud provider. The systems administrator only needs to subscribe to the email service and configure the user accounts and settings.
Question # 4 A DevOps administrator is designing a new machine-learning platform. The application needs to be portable between public and private clouds and should be kept as small as possible. Which of the following approaches would BEST meet these requirements? A. Virtual machines B. Software as a serviceC. Serverless computingD. Containers
Click for Answer
D. Containers
Answer Description Explanation:
Containers are the best approach to design a new machine-learning platform that needs to be portable between public and private clouds and should be kept as small as possible. Containers are isolated environments that can run applications and their dependencies without interfering with other processes or systems. Containers are lightweight, portable, and scalable, which makes them ideal for machine-learning applications. Containers can be moved easily between public and private clouds without requiring any changes or modifications. Containers can also reduce the size and complexity of applications by using only the necessary components and libraries.
Question # 5 A cloud administrator would like to maintain file integrity checks through hashing on a cloud object store. Which of the following is MOST suitable from a performance perspective? A. SHA-256
B. SHA-512
C. MD5D. AES
Click for Answer
C. MD5
Answer Description Explanation :
The most suitable hashing algorithm from a performance perspective to maintain file integrity checks on a cloud object store is MD5 (Message Digest 5). MD5 is a hashing algorithm that generates a 128-bit hash value for any given input data. MD5 is faster and more efficient than other hashing algorithms, such as SHA-256 or SHA-512, which generate longer hash values and require more computational resources. MD5 can be used to verify the integrity of files by comparing their hash values before and after transmission or storage.
Question # 6 A systems administrator is configuring updates on a system. Which of the following update branches should the administrator choose to ensure the system receives updates that are maintained for at least four years? A. LTSB. CanaryC. BetaD. Stable
Click for Answer
A. LTS
Answer Description Explanation:
LTS (Long Term Support) is the update branch that the administrator should choose to ensure the system receives updates that are maintained for at least four years. An update branch is a category or group of updates that have different characteristics or features, such as frequency, stability, duration, etc. An update branch can help customers to choose the type of updates that suit their needs and preferences. LTS is an update branch that provides updates that are stable, reliable, and secure, and are supported for a long period of time, usually four years or more. LTS can help customers who value stability and security over new features or functions, and who do not want to change or upgrade their systems frequently.
Question # 7 A system administrator is migrating a bare-metal server to the cloud. Which of the following types of migration should the systems administrator perform to accomplish this task? A. V2VB. V2PC. P2PD. P2V
Click for Answer
D. P2V
Answer Description Explanation:
P2V (Physical to Virtual) is a type of migration that converts a physical server into a virtual machine (VM). P2V migration can help to move a bare-metal server to the cloud by creating an image of its disk and configuration and uploading it to a cloud platform that supports VM creation from custom images.
Question # 8 A systems administrator is planning to deploy a database cluster in a virtualization environment. The administrator needs to ensure the database nodes do not exist on the same physical host. Which of the following would best meet this requirement? A. OversubscriptionB. Anti-affinityC. A firewallD. A separate cluster
Click for Answer
B. Anti-affinity
Answer Description Explanation:
Anti-affinity is a rule that specifies that certain virtual machines should not run on the same physical host. This can help to improve availability and performance by avoiding single points of failure and resource contention. For example, if the database nodes are running on the same host and the host fails, the entire database cluster will be unavailable. By using anti-affinity rules, the systems administrator can ensure the database nodes are distributed across different hosts in the virtualization environment.
