A cancer diagnostic clinic must transfer a large amount of data to a cloud vendor
to migrate from its on-premises server. However, the amount of data would make
the transfer over the internet take extensive time due to the limited bandwidth
the clinic's internet provides. Instead, it wants to ship an encrypted copy of the
data to the vendor. What type of encryption would BEST fit the clinic's needs?
A.Symmetric algorithm
B.Asymmetric algorithm
C.Plaintext
D.Cryptography
Symmetric algorithm
A security consultant is working with a client to improve security practices. How
can the consultant describe cryptographic hashing so the client is more likely to
accept recommendations?
A.Hashing speeds up the encryption process.
B.Hashing slows down the encryption process.
C.Hashing allows any plaintext length to look the same length as ciphertext.
D.Hashing allows the same length of plaintext to be different lengths of ciphertext.
Hashing allows any plaintext length to look the same length as ciphertext.
Hashing encrypted data makes it much more difficult to break. Hashing takes any
length string and makes it the same length. A hashing algorithm is also useful for
proving integrity.

Which technology replaced NT LAN Manager in Active Directory?
A.Kerberos
B.Virtual Private Network
C.Fast IDentity Online
D.Unique security identifier
Kerberos
The preferred system for network authentication in a Windows environment is
Kerberos, which replaces the legacy system NT LAN Manager (NTLM)
authentication.
The chief information officer (CIO) tasked the network administrator with
redeveloping the credential policy for the company. While working on the new
policy, the chief executive officer (CEO) asked why having more than one factor to
log into the computers was important. Why is just having a password not enough
in today's world?
A.Employees choose poor passwords
B.Employee passwords are always secure
C.Employees dislike using passwords
D.Employees choose strong passwords
Employees choose poor passwords
A software engineer is tasked with identifying vulnerabilities within the network
architecture. When evaluating the use of a particular architecture and selection of
controls, what should not be considered as part of architectural considerations?
A.Port security
B.Costs
C.Availability
D.Risk Transference

Port security
Port Security is not considered an architectural consideration but does prevent a
device attached to a switch port from communicating on the network unless it
matches a given MAC address or other protection profile.
A network administrator conducts an analysis on the company's network in
attempts to determine attack surface, with the intent of reducing exploitable
vectors. When analyzing the potential attack surface, which layer model allows
unauthorized hosts to obtain a valid network address, possibly by spoofing, and
communicate with hosts in other zones?
A.Layer 3
B.Layer 1
C.Layer 4
D.Layer 7
Layer 3
For this scenario, layer 3 allows unauthorized hosts to obtain a valid network
address, possibly by spoofing, and communicate with hosts in other zones.
The security manager at a multinational enterprise is devising a plan to enhance
the physical security of the organization's data center. The data center hosts
critical infrastructure, and a security breach could severely impact operations. The
security manager aims to apply appropriate physical isolation principles to secure
the infrastructure. What critical strategy should the security manager employ to
enhance the data center's physical security through effective physical isolation?
A.Implement biometric security measures at all entry points
B.Install closed-circuit TV surveillance across the office building
C.Establish separate, secure areas for network equipment
D.Increase the number of physical security guards
Establish separate, secure areas for network equipment

A company has expanded its operations to a new location and is setting up its
network infrastructure. A significant part of this setup includes strategically
placing devices for optimal security and efficiency. How should the network
security manager decide the optimal placement of the intrusion detection system
(IDS) in the new network topology to ensure maximum visibility and efficiency
without impacting overall network performance?
A.Place the IDS outside the firewall
B.Place the IDS at the end of the network
C.Place the IDS directly behind the router
D.Place the IDS near the servers
Place the IDS directly behind the router
A network architect at a global financial institution overhauls the company's on-
premises network to enhance security and reduce the attack surface. To
accomplish this, the architect assesses various architecture models and their
respective impact on the on-premises network's security implications. While
redesigning the on-premises network, which architecture derivative/model could
effectively decrease the attack surface?
A.Centralized architecture
B.Peer-to-peer network
C.Content delivery networks
D.Hybrid cloudCentralized architecture
Centralized architecture
Centralized computing architecture refers to a model where all data processing
and storage is performed in a single location, typically a central server. That can
help minimize threat vectors.
