For a software development company looking to implement continuous integration and continuous delivery (CI/CD) pipelines, which cloud computing service would be most effective?
- Amazon EC2
- AWS Lambda
- AWS CodePipeline
- Amazon S3
AWS CodePipeline is a cloud computing service specifically designed for CI/CD pipelines, making it an effective choice for a software development company aiming to implement continuous integration and continuous delivery.
In GRE tunneling, what is a key challenge related to the security of the encapsulated data?
- Lack of Encryption
- Key Management
- Authentication
- Data Compression
A key challenge in GRE tunneling related to the security of the encapsulated data is authentication.
How do reflexive ACLs function differently from standard and extended ACLs?
- Reflexive ACLs are only applicable to IPv6 traffic
- Reflexive ACLs are stateless and filter traffic based on source and destination IP addresses
- Reflexive ACLs are used primarily for routing decisions
- Reflexive ACLs dynamically allow outbound traffic and create temporary entries for inbound traffic
Reflexive ACLs function differently by dynamically allowing outbound traffic and creating temporary entries for inbound traffic, enhancing security by allowing only legitimate responses.
A network engineer is tasked with increasing the bandwidth and redundancy between two core switches. They decide to use EtherChannel. What factors should they consider in this setup?
- DNS configuration, subnet masks, and latency
- IP addressing scheme, routing protocol, and firewall settings
- MAC address table size, spanning-tree configuration, and switch model
- Number of VLANs, load-balancing algorithm, and link speed
In an EtherChannel setup, factors such as the number of VLANs, load-balancing algorithm, and link speed are critical for optimizing bandwidth and redundancy between core switches.
In the TCP/IP model, which layer is responsible for end-to-end data transmission and provides error correction?
- Data Link Layer
- Network Layer
- Physical Layer
- Transport Layer
The Transport Layer in the TCP/IP model is responsible for end-to-end data transmission and provides error correction.
A company is experiencing targeted cyber attacks on its network. Which firewall feature should be implemented for enhanced security?
- Intrusion Prevention System (IPS)
- Stateful Inspection
- Proxy Firewall
- Packet Filtering
An Intrusion Prevention System (IPS) is crucial for detecting and preventing targeted cyber attacks by analyzing network traffic for malicious activity.
________ ACLs are typically used to permit or deny traffic from specific IP addresses.
- Dynamic
- Extended
- Named
- Standard
Standard ACLs are typically used to permit or deny traffic from specific IP addresses.
What mechanism does HSRP use to determine the active and standby routers in a network?
- Priority
- Virtual IP
- MAC Address
- Hello Protocol
HSRP uses priority values to determine the active and standby routers in a network. The router with the highest priority becomes the active router.
In advanced network management, how does SDN (Software-Defined Networking) change the approach to device monitoring?
- Centralized Control
- Increased Latency
- Device-specific Protocols
- Physical Network Isolation
SDN introduces centralized control, allowing for more efficient device monitoring and management by abstracting control from the physical devices.
How does OSPF determine the best route for data packets in its routing table?
- Administrative distance
- Bandwidth
- Cost based on link speed
- Hop count
OSPF (Open Shortest Path First) determines the best route based on the cost, which is calculated using link speed. Lower cost indicates a better route.
