Correct Answer:

fe80 is correct.

Link-local self-assigned IPv6 addresses begin with fe80.

Incorrect Answers:

ff, hh, and 2001 are incorrect.

The prefix ff indicates IPv6 multicast traffic.

The prefix hh is invalid because hexadecimal uses characters 0–9 and a–f.

2001 is the IPv6 global unicast address prefix.

Correct Answer:

Overcommitting disk space, volumes grow as needed is correct.

Thin provisioning overcommits disk space where volumes use the amount of space as needed, but the physical disk space limits still apply.

Incorrect Answers:

Undercommitting disk space, volumes have fixed size, volumes have fixed size that must be accommodated by disk space, and undercommitting disk space, volumes grow as needed are incorrect.

Undercommitting is not a valid term in this context.

Thin provisioning does not apply to fixed volume sizes equaling total disk space.

Undercommitting is not a valid term in this context.

Correct Answer:

Compression can reclaim additional disk space.

Incorrect Answers:

Back up data and then delete it from the server, enable volume shadow copies, and delete log files are incorrect.

Backing up data and then delete is a good idea but removing it from the server makes it unavailable for use.

Volume shadow copies do not save disk space; this feature is used for backup software, file versions, and file undeleting.

Deleting log files is generally not recommended as it may violate organizational security policy.

Correct Answer:

Social engineering is correct.

Social engineering is a range of malicious activities in which the attacker tricks the user into giving away sensitive information such as a password or making a security mistake such as downloading a malicious attachment.

Incorrect Answers:

Backdoor, mantrap, and insider threat are incorrect.

Backdoors are normally planted by attackers to allow them remote access to a compromised system.

A mantrap is a form of physical access control with two sets of doors. Only one set of doors can be open at a time, thus avoiding a tailgating attack.

An insider threat is a threat that comes from within your organization, such as contractors, employees, or business associates. These people may have insider information that can be used to potentially harm the organization.

Correct Answer:

Read and List Folder Contents is correct.

When combining share and NTFS permissions, the most restrictive permissions apply.

Incorrect Answers:

Full Control, Read, and List Folder Contents are incorrect.

Full Control is not the most restrictive permission, so it does not apply.

Read is not the most restrictive permission, so it does not apply.

List Folder Contents is not the most restrictive permission, so it does not apply.

Correct Answer:

Hashing is correct.

Hashing tools take input data fed into an algorithm that results in a unique value, the hash. This can be repeated in the future to detect changes to files.

Incorrect Answers:

Spoofing, defragmentation, and ACL are incorrect.

Spoofing is forgery and can be performed with network traffic using freely available tools.

Defragmentation places file chunks together for better performance.

An access control list (ACL) controls permissions to a resource.

Correct Answer:

Synchronous is correct.

Synchronous replication writes data to multiple locations concurrently without delay.

Incorrect Answers:

Asymmetric, symmetric, and asynchronous are incorrect.

Asymmetric refers to a different yet related security key.

Symmetric means using a single secret key for encryption and decryption.

Asynchronous replication introduces a slight delay before a data write operation completes at an alternate location.

Correct Answer:

`route print` is correct.

`route print` shows the local Windows routing table.

Incorrect Answers:

`netstat`, `routestat`, and `route show` are incorrect.

`netstat` shows network statistics, including port information on the local host.

`routestat` is an invalid command.

`route show` is an invalid command.

Correct Answer:

Hot site is correct.

Hot sites are the most expensive site type because they have everything ready to go at a moment’s notice, including a location, power, communications links, equipment, up-to-date data, and staff.

Incorrect Answers:

Cool site, cold site, and warm site are incorrect.

Cool site is not valid terminology used in disaster recovery.

Cold sites include only a location, power, and communication links.

Warm sites consist of a location, power, communication links, and equipment—they are missing staff as well as up-to-date data.

Correct Answer:

Full duplex is correct.

Full duplex enables simultaneous transmit and receive using the same communication medium.

Incorrect Answers:

Simplex, full simplex, and half duplex are incorrect.

Simplex is analogous to a one-way broadcast transmission.

Full simplex is an invalid term.

Half duplex enables both transmit and receive, but not at the same time.
