Question #:1
A Fibre Channel switch has eight ports and all ports must be operational from 8 AM to 8 PM, Monday through
Friday. However, a failure of Port 7 occurs in the week as follows:
Monday = 11 AM to 12 PM
Wednesday = 4 PM to 9 PM
Thursday = 4 AM to 9 AM
Friday = 2 PM to6 PM
Saturday = 9 AM to 1 PM
What is the availability of Port 7 in that week?
75%
83.3%
80%
68.3%
Answer: B
Explanation
To calculate the availability of Port 7, we need to determine the total downtime during the specified
operational hours and the total operational hours for the week.
Total operational hours:
Monday to Friday: 12 hours/day * 5 days = 60 hours
Total downtime during operational hours:
Monday: 1 hour (11 AM to 12 PM)
Wednesday: 5 hours (4 PM to 9 PM)
Thursday: 0 hours (4 AM to 9 AM is outside operational hours)
Friday: 4 hours (2 PM to 6 PM)
Saturday: 0 hours (Saturday is outside operational hours)
Total downtime = 1 + 5 + 4 = 10 hours

Question #:2
What is a function of the application hardening process'?
Perform penetration testing and validate OS patch management
Disable unnecessary application features or services
Isolate VM network to ensure the default VM configurations are unchanged
Validate unused application files and programs to ensure consistency
Answer: B
Explanation
Application hardening is the process of configuring an application to reduce its attack surface and make it
more secure. The process involves several steps, including removing unnecessary features or services,
enabling security features, configuring access controls, and implementing secure coding practices. By
disabling unnecessary features or services, the application becomes less vulnerable to attacks that exploit these
features or services. For example, an application that does not need to run as a privileged user should be
configured to run with limited privileges. Additionally, disabling or removing unused or unnecessary
application files and programs can help reduce the attack surface. This makes it harder for attackers to exploit
vulnerabilities in the application. Penetration testing and patch management are also important components of
application hardening, but they are not the primary function of the process. Reference: Section 4.2 Security
Hardening and Monitoring, page 228.

B. 
C. 
Answer: C
Explanation
The Network layer (Layer 3) of the OSI reference model is responsible for logical addressing and routing. This
layer provides the functional and procedural means of transferring variable-length data sequences from a
source to a destination via one or more networks while maintaining the quality of service requested by the
Transport layer. Logical addressing is implemented using IP addresses, and routing determines the best path
for data to travel across the network.

Question #:4
What is the effect of implementing link aggregation in an FC SAN environment?
Distributes network traffic over ISLs that ensures even ISL utilization
Yields higher throughput by combing two parallel ISLs into a single physical ISL
Saves bandwidth by restricting traffic to a specific potentially congested ISL
Improves ISL utilization by increasing network traffic on a specific ISL
Answer: A
Explanation
Implementing link aggregation in a Fibre Channel (FC) Storage Area Network (SAN) environment distributes
network traffic over Inter-Switch Links (ISLs), ensuring even utilization of these links. Link aggregation
combines multiple physical ISLs into a single logical link, allowing for balanced traffic distribution and
improved redundancy. This helps to avoid congestion on any single ISL, thus enhancing overall network
performance and reliability.

Backup device
Backup server
Answer: D
Explanation
The backup server is responsible for managing the backup operations, including sending metadata and tracking
information about each backup to the system that maintains this information. This centralized management
ensures that backup processes are monitored, and data integrity is maintained.

Question #:6
In a data archiving environment, which component scans primary storage to find the files that are required to
archive?
Archive stub file
Archive agent
Archive storage
Archive database server
Answer: B
Explanation
In a data archiving environment, the archive agent is responsible for scanning primary storage to identify files
that need to be archived. The agent looks for files based on specific criteria such as age, size, and access
frequency, then initiates the archiving process by moving or copying the files to the archive storage. This helps
in managing storage efficiently by freeing up space on primary storage.References: Dell Information Storage
and Management V5 documents, ExamTopics.
Question #:7
A user lost access to a key VM due to a hardware failure. A proxy server regularly takes PIT snapshots of the
VM to protect the data.
What type of data protection method is this called'?
Agent-based

Local replication
Image-based
Answer: D
Explanation
This is an example of an image-based data protection method. With image-based data protection, a proxy
server regularly takes Point-in-Time (PIT) snapshots of the virtual machine (VM) that is being protected.
These snapshots are then stored in a secure location, allowing the user to quickly restore access to the VM in
the event of a hardware failure. This type of data protection is effective for preserving the state of the VM, as
well as any data stored on it, making it a reliable and secure way to protect data.
Question #:8
What is a benefit of including a Defense-in-depth strategyas part of the data center security strategy?
Optimize application and data storage security controls
Optimize application and network security controls
Reduce the overall cost of deploying security controls
Reduce the scope of an information security risk
Answer: D
Explanation
A Defense-in-depth strategy involves multiple layers of security controls to protect data and IT resources. By
having various defense mechanisms, the risk of a security breach is minimized, as compromising one layer
does not compromise the entire system. This layered approach significantly reduces the overall risk and impact
of potential security threats.

A. 
B. 
C. 
D. 
Answer: B
Explanation
Capacity is a management monitoring parameter that involves examining the amount of infrastructure
resources used. This includes monitoring storage capacity, network bandwidth, CPU utilization, memory
usage, and other resources. Capacity management is important for ensuring that the infrastructure has
sufficient resources to meet the demands of the business or customers. It involves predicting future resource
needs, identifying capacity bottlenecks, and optimizing resource utilization to avoid performance degradation
or service disruptions. Reference: Section 2.2.2 Infrastructure Resource Monitoring, page 76.
Question #:10
What is a function of the metadata service in an OSD storage system?
Generates an object ID from the data to be stored
Manages the file system storage space for all remote clients
Generates the file system namespace from the data to be stored
Manages physical OSD containers on which data is stored
Answer: A
Explanation
In an Object-based Storage Device (OSD) system, the metadata service plays a crucial role by generating a
unique object ID for each piece of data to be stored. This ID is used to manage and retrieve the data objects.
The metadata service also keeps track of the attributes and locations of objects, enabling efficient data access
and management within the storage system.
