Which protocol is commonly used for VLAN tagging on trunk links in a Cisco environment?
- 802.1Q
- ARP
- ICMP
- STP
The 802.1Q protocol is commonly used for VLAN tagging on trunk links in a Cisco environment.
What is a primary disadvantage of dynamic routing compared to static routing in terms of resource usage?
- Dynamic routing consumes fewer resources as it dynamically adjusts to network changes.
- Dynamic routing protocols require more resources, such as bandwidth and processing power, compared to the simplicity of static routing.
- Resource usage is similar for both dynamic and static routing.
- Static routing consumes more resources due to the manual configuration of routes.
Dynamic routing, due to its continuous exchange of routing information, demands more resources, including bandwidth and processing power, compared to the more static nature of static routing.
In Cisco routers, what is the implicit rule at the end of every ACL?
- Allow all
- Deny all
- Deny any
- Permit any
In Cisco routers, the implicit rule at the end of every ACL is to deny any traffic that has not been explicitly permitted.
When designing a network for a multinational corporation with various branch offices and data centers, which technique is essential to manage the routing tables effectively?
- Border Gateway Protocol (BGP)
- Multi-Protocol Label Switching (MPLS)
- Route Summarization
- Virtual Private Networks (VPNs)
Route summarization is essential when designing a network for a multinational corporation with various branch offices and data centers to manage the routing tables effectively, reducing the size and complexity of routing information.
DNS primarily translates which of the following?
- IP addresses to domain names
- Hostnames to IP addresses
- MAC addresses to IP addresses
- IP addresses to MAC addresses
DNS (Domain Name System) primarily translates hostnames to IP addresses, allowing users to access resources using human-readable names.
The _______ feature of EtherChannel helps in avoiding network loops and provides redundancy.
- Load Balancing
- Loop Guard
- Port Security
- Redundancy
The Loop Guard feature of EtherChannel helps in avoiding network loops and provides redundancy.
Which routing protocol is classful and does not support VLSM or CIDR?
- EIGRP
- OSPF
- RIP
- RIPv1
RIPv1 (Routing Information Protocol version 1) is a classful routing protocol that does not support Variable Length Subnet Masking (VLSM) or Classless Inter-Domain Routing (CIDR).
________ allows for multiple virtual router identifiers (VRIs) to be assigned to different interfaces on the same router.
- HSRP
- GLBP
- VRRP
- OSPF
GLBP (Gateway Load Balancing Protocol) allows for multiple virtual router identifiers (VRIs) to be assigned to different interfaces on the same router.
When configuring EtherChannel on a switch, the ______ of the ports being aggregated must match.
- Duplex
- IP Address
- Speed
- VLAN
When configuring EtherChannel on a switch, the speed of the ports being aggregated must match.
_________ is a protocol that automatically assigns IP, subnet mask, gateway, and DNS information to network devices.
- DHCP
- DNS
- SNMP
- TCP
DHCP (Dynamic Host Configuration Protocol) is a protocol that automatically assigns IP, subnet mask, gateway, and DNS information to network devices.
What is a key advantage of using SDN in data center networks?
- Improved Scalability
- Reduced Latency
- Increased Security
- Enhanced Redundancy
A key advantage of using SDN in data center networks is improved scalability.
How is the coin change problem related to dynamic programming?
- Dynamic programming is employed to solve subproblems efficiently and avoid redundant calculations.
- Dynamic programming is only applicable to certain variations of the problem.
- Dynamic programming is used to count the total number of coins, but not for optimization.
- It isn't related to dynamic programming.
The coin change problem is related to dynamic programming as it involves solving subproblems efficiently and storing their solutions to avoid redundant calculations. Dynamic programming is used to find the optimal combination of coins to minimize the total count.
