A network engineer is configuring a GRE tunnel to connect two remote sites over the internet. What additional security mechanism should they consider implementing to protect the data?
- IPsec
- SSL
- TLS
- SSH
When configuring a GRE tunnel, additional security can be provided by implementing IPsec to encrypt the data transmitted between the remote sites over the internet.
If a network administrator is configuring a router to connect different IP networks, which layer of the TCP/IP model are they primarily working with?
- Application
- Data Link
- Network
- Transport
The network layer of the TCP/IP model (equivalent to the OSI model's Layer 3) is primarily responsible for routing and connecting different IP networks.
To avoid overlapping subnets in VLSM, network administrators must ensure ________ between subnet boundaries.
- Consistency
- Continuity
- Separation
- Synchronization
To avoid overlapping subnets in VLSM, network administrators must ensure separation between subnet boundaries.
A network engineer needs to configure a device to send real-time alerts for specific events. Which SNMP component should they configure?
- SNMP Manager
- SNMP Agent
- SNMP Trap
- SNMP Get
To send real-time alerts for specific events, the SNMP Trap component should be configured on the device. SNMP Trap allows devices to send unsolicited messages (traps) to a central SNMP manager.
What is the primary purpose of DHCP in a network?
- Assigning IP addresses dynamically
- Resolving domain names to IP addresses
- Managing network security
- Establishing physical connections
DHCP (Dynamic Host Configuration Protocol) is primarily used for dynamically assigning IP addresses to devices on a network.
In an organization, an auditor requires a system that can report on all individual user activities across network devices. Which aspect of AAA should be emphasized?
- Authentication
- Authorization
- Accounting
- Auditing
The Accounting aspect of AAA (Authentication, Authorization, and Accounting) is emphasized when reporting on individual user activities across network devices.
A company's security policy requires masking the internal IP addresses when accessing external websites. What configuration should the network engineer implement?
- Dynamic NAT
- NAT Overload
- PAT
- Static NAT
Static NAT should be implemented to mask internal IP addresses when accessing external websites, as it provides a one-to-one mapping of internal and external addresses.
An IPv4 address is typically divided into two parts: the ________ and the host identifier.
- Gateway
- Network portion
- Prefix
- Subnet portion
An IPv4 address is typically divided into two parts: the network portion and the host identifier. The network portion identifies the network to which the host belongs.
