1. What does VRRP stand for in the context of network protocols?
Virtual Routing Redundancy Protocol
Virtual Redundancy Routing Protocol
Virtual Router Redundancy Protocol
Virtual Redundant Routing Protocol
2. Which of the following statements correctly defines jamming?
An attacker circumvents the security protections in the company's
network, accessing the network behind the firewall.
An attacker creates false deauthentication or disassociation management
frames that appear to come from another client device, causing the client
to disconnect from the AP.
An attacker intentionally floods the RF spectrum with extraneous RF
signal "noise" that creates interference and prevents communications.
An attacker tries to mimic an authorized AP, so a user's mobile device
such as a laptop or tablet unknowingly connects to the evil twinUnindsetrestaad

test.
SLIP operates at the Data Link layer and does not provide error
correction. Got it
SLIP operates at the Transport layer and ensures reliable delivery.
SLIP operates at the Application layer and manages user sessions.
,4. Which of the following is a small file that contains a user's public key and
identifying information?
Asymmetric encryption
Private key
Digital certificate
Digital signature
5. What is the primary function of a stateful firewall in network security?
To block all incoming traffic
To inspect packets based on predefined rules
To track the state of active connections
To encrypt data during transmission
6. If a company decides to implement HTTPS on its website, which of the following
actions must it take to ensure secure communications?
Obtain an SSL/TLS certificate and configure the server to use TCP port
443.
Disable all firewalls and use TCP port 80.
Only use HTTP without any encryption.
Increase the bandwidth of the server.
7. A denial of service (DoS) attack is:
A security threat that relies on cleartext transmission, whereby the
assailant falsifies the IP addresses of an Internet server by chaning the
address recorded in packets it sends over the internet.
A synchronized attempt to deny service to authorize users by causing a
computer to perform a task over and over.
, A form of social engineering whereby an intruder pretends to be a
legitimate entity and contacts unwary users asking them to reconfirm their
personal information.
A destructive program that's disguised as a legitimate or harmless
program that carries within itself the means to allow the program's creator
to secretly access the user's system.
8. Explain how a hypervisor contributes to the functionality of virtual switches in a
virtualized environment.
It directly connects physical switches to virtual machines.
It manages the allocation of network resources among virtual
machines.
It encrypts data packets sent between virtual machines.
It monitors network traffic for security threats.
9. Which of the following is true about ACLs on Cisco routers?
ACLs are processed in reverse order so place high priority statements last
there is an explicit permit any statement at the beginning of the ACL
ACLs bound to an interface apply to inbound and outbound traffic by
default
there is an implicit deny any statement at the end of the ACL
10. If a company implements a strong password policy that requires passwords to
be at least 12 characters long and include a mix of letters, numbers, and
symbols, how would this affect the effectiveness of a dictionary attack?
It would make the dictionary attack more effective due to the complexity
of the passwords.
It would have no effect on the dictionary attack since it only relies on
common words.
, It would significantly reduce the effectiveness of a dictionary attack by
increasing the number of possible combinations.
It would eliminate the possibility of a dictionary attack entirely.
11. Which of the following activities is implemented to check whether an
organization is following a set of standard policies and procedures in protecting
its network?
Ethical hacking
Vulnerability assessment
Security audit
Penetration testing
12. Which of the following terms best describes a file containing verified
identification information about the user and the user's public key?
Certificate Authority
Private Key
Digital Certificate
Cipher
13. Explain the significance of using CIDR notation for summarizing IP addresses in
a network.
It allows for more efficient routing by reducing the number of entries
in a routing table.
It is used solely for security purposes in network management.
It provides a way to assign static IP addresses to devices on a network.
It is primarily used for defining the maximum bandwidth of a network.
