For dynamic EtherChannel configuration, _______ is typically used in a Cisco environment, while _______ is a standard protocol supported by multiple vendors.
- GLBP, HSRP
- HSRP, GLBP
- LACP, PAgP
- PAgP, LACP
For dynamic EtherChannel configuration, LACP (Link Aggregation Control Protocol) is typically used in a Cisco environment, while PAgP (Port Aggregation Protocol) is a standard protocol supported by multiple vendors.
A subnet mask of 255.255.255.192 indicates a ________ subnet size.
- Large
- Medium
- Small
- Variable
A subnet mask of 255.255.255.192 indicates a medium-sized subnet.
What WAN technology is characterized by its ability to provide a scalable and efficient VPN solution?
- MPLS
- Frame Relay
- DSL
- ISDN
MPLS (Multiprotocol Label Switching) is characterized by its ability to provide a scalable and efficient VPN (Virtual Private Network) solution.
________ ACLs are more specific and versatile than standard ACLs, as they can filter packets based on port numbers and protocol types.
- Dynamic
- Extended
- Named
- Standard
Extended ACLs are more specific and versatile than standard ACLs, allowing filtering based on port numbers and protocol types.
Which protocol is used to encrypt management sessions with network devices?
- SNMP
- HTTPS
- Telnet
- ICMP
HTTPS (Hypertext Transfer Protocol Secure) is the protocol used to encrypt management sessions with network devices, ensuring secure communication for managing devices.
A network administrator notices that their AS is receiving suboptimal BGP routes. What BGP attribute should they adjust to influence incoming traffic paths?
- Local Preference
- AS Path
- MED (Multi-Exit Discriminator)
- Weight
The Local Preference attribute in BGP is adjusted to influence incoming traffic paths. It is used within the same AS to set preferences for routes.
In a network with multiple switches, how does the Spanning Tree Protocol (STP) determine the root bridge?
- Highest MAC address
- Highest bridge priority
- Lowest MAC address
- Lowest bridge priority
The Spanning Tree Protocol (STP) determines the root bridge based on the lowest bridge priority. If priorities are the same, it uses the lowest MAC address as a tiebreaker.
In a multi-homed network environment, what BGP strategy could be employed to avoid being a transit AS for other networks?
- Weight
- Local Preference
- AS Path Prepending
- Route Reflectors
AS Path Prepending is a BGP strategy in a multi-homed network to avoid being a transit AS for other networks. It adds the AS number multiple times to make the path less favorable.
IPv6 uses _________ to simplify and improve aspects of IP address assignment and network renumbering.
- Dynamic Host Configuration Protocol (DHCPv6)
- Internet Control Message Protocol version 6 (ICMPv6)
- Routing Information Protocol version 6 (RIPng)
- Stateless Address Configuration (SLAAC)
IPv6 uses Stateless Address Configuration (SLAAC) to simplify and improve aspects of IP address assignment and network renumbering.
The _______ record in DNS is used to point a domain to a physical IP address.
- A
- MX
- CNAME
- PTR
The CNAME (Canonical Name) record in DNS is used to point a domain to a physical IP address.
